Description
Technical Field
The invention relates to a clutch, in particular to a clutch mechanism and a clutch.
Background
Chinese patent discloses a clutch mechanism and a friction plate type overrunning clutch with the application number 201610765079.6. The clutch mechanism comprises a driving piece, a driven piece axially opposite to the driving piece, a limiting piece sleeved on the driving piece and/or the driven piece to limit the relative rotation angle of the driving piece and the driven piece, and a rolling body arranged between the driving piece and the driven piece. The driving part is provided with a plurality of first V-shaped slopes facing one side of the driven part, a plurality of second V-shaped slopes matched with the first V-shaped slopes are arranged facing one side of the driven part, and the rolling bodies are arranged between the first V-shaped slopes and the second V-shaped slopes. Although the clutch mechanism reduces the friction between the first V-shaped slope surface and the second V-shaped slope surface to a certain extent when the driving piece and the driven piece perform relative rotation movement through the design of the rolling bodies, the clutch mechanism still has the following defects:
1) The rolling bodies only play a role in reducing friction between the first V-shaped slope surface and the second V-shaped slope surface, the layout mode of all the rolling bodies is designed by matching the shapes of the first V-shaped slope surface and the second V-shaped slope surface, the rolling bodies cannot replace the roles of the first V-shaped slope surface and the second V-shaped slope surface, and the layout after the rolling bodies are installed is completely determined according to the shapes of the first V-shaped slope surface and the second V-shaped slope surface, so that the installation work of all the rolling bodies is troublesome, the processing precision requirement is very high, the production cost is improved, meanwhile, in order to facilitate the installation, only the rolling bodies are separated from the first V-shaped slope surface and the second V-shaped slope surface, all the rolling bodies are installed on one retainer, and when the driving piece and the driven piece relatively rotate, the retainer relatively moves with the driving piece and the driven piece at the same time, so that the rotation between the driving piece and the driven piece is not smooth, and the rolling piece still have certain friction with the rolling bodies or the retainer, and the rolling bodies are easy to fall off from the retainer, and the service life of the driving piece and the driven piece is short;
2) The processing precision of the first V-shaped slope surface and the second V-shaped slope surface is higher, so that the processing cost is higher;
3) Because the first V-shaped slope surface and the second V-shaped slope surface are required to provide a processing foundation, the axial size of the driving piece and the driven piece is larger after the driving piece and the driven piece are together, and the size of the whole clutch is increased.

In order to achieve the above purpose, the present invention adopts the following technical scheme:
The present invention first provides a clutch mechanism, comprising: a first rotating member and a second rotating member;

The second rotating piece is provided with a first rolling body, the first rotating piece is provided with an action surface for contacting with the first rolling body, and the first rolling body provides an arc surface contacting with the action surface;
when the first rotating piece and the second rotating piece rotate relatively, the action surface provides a motion track for the first rolling body; and is also provided with
The second rotating member can relatively displace with the first rotating member in the axial direction only through the cambered surface.
As a preferred embodiment of the invention, the first rolling element is fixed to the second rolling element.
As a preferred embodiment of the present invention, the first rolling body is capable of rotating.
As a preferred embodiment of the present invention, the first rolling element is mounted on the second rotating member through a mounting sleeve fixed to the second rotating member, the mounting sleeve and the second rotating member forming a rotation hole through which the first rolling element rotates; the first rolling bodies are arranged in the rotating holes of the mounting sleeve.
As a preferred embodiment of the present invention, the first rolling element is mounted on the second rotating member by a mounting assembly comprising: the mounting sleeve is fixed on the second rotating piece, and a rotating hole for the first rolling body to rotate is formed between the mounting sleeve and the second rotating piece; the first rolling body comprises a rolling ring and a mounting ring, the mounting ring is fixed relative to the second rotating piece, the rolling ring surrounds the mounting ring, the rolling ring can rotate relative to the mounting ring, and the mounting ring extends out of the rolling ring.
As a preferred embodiment of the invention, the first rolling bodies further comprise a number of second rolling bodies, which are arranged between the rolling ring and the mounting ring.
In a preferred embodiment of the present invention, the action surface is a V-shaped slope surface, and the V-shaped slope surface includes a first contact surface and a second contact surface, and the first rolling element is displaced on the first contact surface or the second contact surface.
In a preferred embodiment of the present invention, the acting surface is an arc surface, and the arc surface is formed by recessing a side surface of the first rotating member, which is close to the second rotating member.
The invention also provides a clutch which comprises the clutch mechanism, wherein the clutch mechanism is used as the clutch mechanism of the clutch and is also used as a transmission mechanism of a driving device force, and the force of the driving device is transmitted to a piece to be driven through a separation and combination structure.
Further, the clutch further comprises a limiting piece, a central shaft and a driven friction disc, wherein a friction plate is arranged between the first rotating piece or the second rotating piece and the driven friction disc, and the limiting piece is used for limiting the relative rotation direction of the first rotating piece and the second rotating piece and limiting the rotation angle of the first rotating piece relative to the second rotating piece.
Compared with the prior art, the invention has the following beneficial effects:
1) Because the relative movement between the rolling bodies with the retainers and the first rotating piece and the second rotating piece is also carried out in the process of relative rotation between the first rotating piece and the second rotating piece, and the rolling bodies with the retainers and the first rotating piece and the second rotating piece can be damaged due to the friction between the rolling bodies with the retainers, the application prolongs the service life; in addition, the interference of each rolling body with the retainer on the relative movement between the first rotating piece and the second rotating piece enables the sliding of the first rolling body on the v-shaped surface to be smoother, namely when the first rotating piece and the second rotating piece rotate relatively, and after the larger first rolling body is arranged on the second rotating piece, the first rolling body can rotate more smoothly, the axial displacement generated between the first rotating piece and the second rotating piece is faster, namely the sensitivity is higher, the rolling body with the retainer is arranged between the two v-shaped surfaces and is difficult to predict, and the sensitivity is higher to meet the actual requirements;
2) The conventional rolling bodies are only arranged in the first rotating member and the second rotating member (namely in the driving member and the driven member) to reduce friction, but in the prior art, the first rolling body has the function of one v-shaped surface in the application number 201610765079.6, and in the patent with the application number 201610765079.6, the rolling bodies replace the function of one v-shaped surface, so that the processing of one v-shaped surface can be reduced, and the processing cost is reduced; because each small rolling body in the prior art needs to be arranged on a retainer, and all rolling bodies need to be enclosed into a shape matched with the rolling bodies, the processing difficulty of all the rolling bodies in the prior art is high, the shape of two v-shaped surfaces is identical, and the processing difficulty is quite difficult, the application discovers the difficult problem, and the processing step is greatly simplified by processing the first rolling body instead of processing one v-shaped surface, only one action surface (which is equivalent to the v-shaped surface in the prior art), and the installation of the larger first rolling body is quite convenient;
3) In the prior art, the rolling bodies are arranged between two v-shaped surfaces, two solid foundations are needed for the arrangement of the two v-shaped surfaces, and only one v-shaped surface is needed for the arrangement of the two v-shaped surfaces, so that the axial sizes of the first rotating member and the second rotating member are reduced;
4) In the prior art, the combination and disconnection of the two friction plates are driven by the action of the rolling bodies and the smooth grooves, but the power for driving the combination and disconnection of the two friction plates is driven by external force, a control device (used for controlling the combination and disconnection of the two friction plates) is added, the use cost is increased, a clutch structure is increased by adding one control device, the rotating output does not need to pass through the rolling bodies, and the control device can not drive the friction plates to rotate through the rolling bodies and the grooves after the friction plates are combined.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention more clear and easy to understand, the present invention is further described below with reference to the accompanying drawings and the detailed description:
example 1:
A clutch mechanism comprising: a first rotating member 11 and a second rotating member 12;
The first rotating member 11 is used for connecting a driving device (the driving device is typically an output shaft of an engine) or a member to be driven (the member to be driven is typically an active friction plate), and the second rotating member 12 is connected to the member to be driven when the first rotating member 11 is connected to the driving device; the second rotating member 12 is connected to the driving device when the first rotating member 11 is connected to the member to be driven; (it will be appreciated that the first rotating member 11 may be a driving member as in claim 201610765079.6 or a driven member as in claim 201610765079.6, where the first rolling element 13 is on one of the driving member and the driven member, and the first rolling element 13 is on the other of the driving member and the driven member)
The second rotating member 12 is provided with a first rolling element 13, the first rotating member 11 is provided with an action surface 111 for contacting the first rolling element 13, and the first rolling element 13 provides an arc surface contacting the action surface 111 (this is a main difference point from the prior art);
when the first rotating member 11 and the second rotating member 12 relatively rotate, the acting surface 111 provides a motion track for the first rolling element 13; and the second rotating member 12 can be displaced relative to the first rotating member 11 in the axial direction only through the cambered surface.
The number of the first rolling elements 13 and the number of the working surfaces 111 are preferably three, because three points form one surface, and the number is more than three, which leads to improvement of processing accuracy. The number of the friction plates is less than three, and the geometrical relationship between the joint surface of the friction pair and the central shaft is not easy to control because a plane cannot be determined, so that the problem that the friction plates are not thoroughly separated or are not well combined is caused.
In order to further increase the sensitivity, the first rolling elements 13 are capable of rotating. (of course, it is also possible that the first rolling element is fixed relative to the second rotating member 12, the first rolling element protrudes out of the second rotating member 12, and the first rolling element is in a shape of a partial cylinder, so that there are various fixing modes of the first rolling element and the second rotating member 12, and the first rolling element and the second rotating member may be integrally formed or may be mounted together by means of an external member)
There are many ways in which the first rolling bodies 13 are mounted on the second rolling member 12, and the first rolling bodies 13 may be integrally formed with or separately mounted from the second rolling member 12. Referring to fig. 8, the first rolling elements 13 are integrally mounted on the second rotating member 12 or detachably mounted on the second rotating member 12.
In this embodiment, referring to fig. 2, the first rolling element 13 is mounted on the second rotating element 12 through a mounting assembly;
the mounting assembly includes: a mounting sleeve 14, a mounting sleeve 14 is fixed on the second rotating member 12, the mounting sleeve 14 and the second rotating member 12 form a rotating hole for the first rolling element 13 to rotate, in order to conveniently mount the first rolling element 13, the mounting sleeve 14 and the second rotating member 12 are integrally formed, if the first rolling element 13 can rotate, the first rolling element 13 must be separately processed with the second rotating member 12, the mounting sleeve 14 is provided for providing a mounting space for the first rolling element 13, and a bolt is provided for realizing the connection between the first rolling element 13 and the mounting sleeve 14, of course, the bolt is not provided, and the first rolling element 13 and the mounting sleeve can be in interference connection (this is one mounting mode of the first rolling element 13 and the mounting sleeve 14, of course, other mounting modes are also available);
The first rolling element 13 includes a rolling ring 131, a mounting ring 132, and a second rolling element 133, the mounting ring 132 is fixed relative to the second rotating member 12 (the fixing manner is that the mounting ring 132 is connected with the mounting sleeve 14 through a bolt, and of course, other fixing manners are also possible), the rolling ring 131 surrounds the mounting ring 132, a plurality of second rolling elements 133 are disposed between the rolling ring 131 and the mounting ring 132, the rolling ring 131 can rotate relative to the mounting ring 132, and the mounting ring 132 extends out of the rolling ring 131. So that the rolling ring 131 can rotate on the mounting ring 132 more smoothly by the second rolling bodies 133.
The action surface 111 is a V-shaped slope, the V-shaped slope is formed by recessing one side surface of the first rotating member 11, which is close to the second rotating member 12, the V-shaped slope comprises a first contact surface and a second contact surface, one edge of the first contact surface is close to the other edge of the second contact surface, and the first rolling body 13 walks on the first contact surface or the second contact surface. ( That is, the V-shaped slope has two farthest positions (i.e. the distance between the position of the first rolling element 13 and the side surface of the first rotating element 11 facing away from the second rotating element 12 is farthest), the two farthest positions are respectively located at two sides of the nearest position, the two farthest positions respectively correspond to one gear, such as a reverse gear and a forward gear, the first rolling element 13 can only move back and forth between the two farthest positions, so that when the first rolling element 13 reaches a farthest position, the continuous relative movement of the first rotating element 11 and the second rotating element 12 can be limited, and finally, the purpose that the first rotating element 11 drives the second rotating element 12 to rotate or the second rotating element 12 drives the first rotating element 11 to rotate is achieved; when the first rolling element 13 reaches the nearest position (i.e., the position of the first rolling element 13 reaches the side surface of the first rotating element 11 facing away from the second rotating element 12 closest to the first rotating element), the first rotating element 11 does not force the driving friction plate to contact with the driven friction plate through the first rolling element 13 and the contact portion, so that the purpose of reaching the neutral position can be achieved. )
Example 2:
This embodiment differs from embodiment 1 only in that: the first rolling body is fixed with the second rotating piece. The surface of the first rolling body, which is used for being in contact with the acting surface, is a curved surface, and the curved surface is a side wall when the first rolling body is a cylinder, or can be a side wall when the first rolling body is an elliptic cylinder.
Example 3:
this embodiment differs from embodiment 1 only in that: the shape of the active surface is different.
The action surface is a slope surface, the slope surface is formed by a convex part of the first rotating piece, which is close to the second rotating piece, and an included angle is formed between the plane of the slope surface and the axial direction of the first rotating piece. That is, the slope surface has only one farthest position, one farthest position and one nearest position correspond to one gear, for example, one neutral position and one forward gear, and the first rolling element can only move back and forth between the farthest position and the nearest position, so that when the first rolling element reaches the farthest position, the continuous relative movement of the first rolling element and the second rolling element can be limited, and finally, the purpose that the first rolling element drives the second rolling element to rotate or the second rolling element drives the first rolling element to rotate is achieved; when the first rolling element reaches the nearest position, the first rotating element does not force the driving friction plate to be in contact with the driven friction plate through the first rolling element and the contact part, so that the aim of reaching the neutral position can be fulfilled. )
Example 4:
this embodiment differs from embodiment 1 only in that: the shape of the active surface is different.
The action surface is an arc surface which is formed by recessing the side surface of the first rotating piece, which is close to the second rotating piece. (namely, the arc surface has two farthest positions, the two farthest positions are respectively positioned at two sides of the nearest position, the two farthest positions respectively correspond to a gear, such as a reverse gear and a forward gear, the first rolling body can only move back and forth between the two farthest positions, so that when the first rolling body reaches the farthest position, the continuous relative movement of the first rolling body and the second rolling body can be limited, the purpose that the first rolling body drives the second rolling body to rotate or the second rolling body drives the first rolling body to rotate is finally achieved, when the first rolling body reaches the nearest position, the first rolling body does not force the driving friction plate to contact with the driven friction plate through the first rolling body and the contact part, the purpose of reaching the neutral position can be achieved, the shape of the arc surface is more attached to the shape of the first rolling body, the first rolling body rolls more smoothly in a groove taking the arc surface as the bottom surface, and the service life is further prolonged).
Example 5:
As shown in fig. 1 and 2, a clutch includes: the limiting member 15, the driving friction plate 16, the driven friction plate 17 and the clutch mechanism as described in any one of embodiment 1 to embodiment 4 are disposed beside the first rotating member 11 and the second rotating member 12, so as to limit the relative rotation direction of the first rotating member 11 and the second rotating member 12 and limit the rotation angle of the first rotating member 11 relative to the second rotating member 12.
It should be emphasized that, referring to fig. 5, the force of the conventional clutch driving device is transmitted in a direction in which the power is directly transmitted to the tire (to-be-driven member) through the transmission mechanism of the gearbox. The disconnecting and coupling mechanism only acts as a disconnecting switch, and is not responsible for the transmission of the drive force itself. In addition, the conventional clutch needs to introduce other power sources, such as an external force source such as manual stepping or external electromagnetic force, for controlling the separation and combination of the separation and combination mechanism, so that the conventional clutch has a complex structure, high cost and low reaction speed and is easy to fail.
Referring to fig. 6, the direction of the driving device of the clutch of the present invention is that the power is transmitted to the tire (the member to be driven) through the separation and combination mechanism and the transmission mechanism. The separation and combination mechanism not only plays a role of a separation switch, but also plays a role of transmitting a driving device, and the force of the driving device can directly transmit main driving force through the separation and combination mechanism. The separation and combination mechanism utilizes the rotation speed difference of the first rotating piece and the second rotating piece, so that the axial displacement of the first rotating piece and the second rotating piece is caused, and the separation and combination are realized. Compared with the traditional clutch, the clutch does not need to introduce other external force sources to control the separation and combination, so that the clutch has a simple structure, is greatly reduced in cost and is not easy to fail.
With continued reference to FIG. 7, FIG. 7 is an assembled view of the clutch of the present invention. In the clutch, the transmission direction of the drive force is shown by the arrow direction in fig. 7. The positional connection relationship of the separation coupling device 203, the driven friction plate 202, and the center shaft 201 is shown.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
