Description

[0001] The present invention relates to a rolling contact type inhibitor switch,

The present invention relates to an inhibitor switch for a transmission, and more particularly to a rolling contact inhibitor switch to which a free rotation roller is applied.

Generally, the inhibitor switch mounted on the automatic transmission housing controls the transmission signals P, R, N, D of the automatic transmission by the shift lever operation to the TCU (Transmission Control Unit) (or MCU The MCU determines whether or not the angle control valve is operated according to the transmission signal transmitted from the TCU, and the angle control valve determines the supply direction of the working fluid supplied through the solenoid valve Thereby selectively supplying the working fluid to the plurality of friction elements.

Fig. 6 shows an example of an axial contact inhibitor switch. As shown in the figure, the axial contact type inhibitor switch 1-1 includes a manual control shaft 100 rotating in conjunction with a shift lever, a control shaft 100 and a fixed moving block 200, a moving block 200 A moving contactor 300 which is installed vertically to the moving connector 300 and receives the axial spring force Fdown, a terminal 400 which maintains contact with the moving contactor 300 under the moving connector 300, And a cover 600 that shields the housing 500 from the outside, while the terminal 500 is provided with a space for accommodating the moving block 200 coupled to the terminal 400.

Korean Patent Laid-Open Publication No. 10-2000-0066788 (November 15, 2000)

However, the axial contact inhibitor switch 1-1 has the following disadvantages.

First, the silver plating of the moving contactor 300 may cause abrasion due to abrasion to deteriorate contact performance with the terminal 400. Second, since the contact state between the moving contactor 300 and the terminal 400 is supported by the cover 600 together with the axial spring force Fdown, the application of the aluminum cover 600 for securing a sufficient rigidity increases the cost. Third, when the cover 600 is not assembled to the housing 500, the contacting force between the moving contactor 300 and the terminal 400 is affected, thereby deteriorating the contact performance between the moving contactor 300 and the terminal 400 . Fourthly, the axial spring force Fdown for pressing the moving contactor 300 is directly formed by the spring, resulting in a contact imbalance between the moving contactor 300 and the terminal 400 according to the spring seating state. Fifth, When the manual control shaft 100 is bolted to the transmission case, the manual control shaft 100 is also tilted and assembled, resulting in excessive operation force during assembly. Sixth, since the spring mounting space of the moving block 200 is short, it is difficult to attach the long spring, so that it is inevitably affected by the contact force depending on the mounting length change.

In view of the above, the present invention minimizes contact wear due to rolling contact between the moving contactor and the terminal in the circumferential direction for switching the contact signal for each gear position, and in particular, the contact state between the moving contactor and the terminal is controlled by the circumferential spring force Contact type inhibitor switch in which the contact performance is maintained firmly.

In order to achieve the above object, the rolling contact inhibitor switch of the present invention includes a moving block, a manual control shaft connected to a shift lever, A moving contactor arranged in the circumferential direction of the moving block and rotated together with the moving block; A terminal forming a turning radius for rolling contact with the moving contactor and forming a transmission ON / OFF signal pattern by a rotation angle change of the moving contactor; Is included.

In a preferred embodiment, the moving contactor is inserted into a sliding groove formed in a circumferential direction of the moving block, the moving contactor having a contact roller that is out of the sliding groove, the contact roller is in rolling contact with the terminal, The contact roller is engaged with a contact guide inserted into the sliding groove, and the contact guide is elastically supported in the sliding groove by a spring pushing the contact roller toward the terminal by a circumferential spring force Fside.

In a preferred embodiment, the contact guide forms a free rotation structure of the contact roller with a tridentally-shaped coupling end, and receives the spring with a spring groove. The center portion of the trident shape of the coupling end is formed longer than both the left and right portions.

 In a preferred embodiment, the contact roller and the terminal are respectively silver plated.

In a preferred embodiment, the transmission ON / OFF signal pattern is input to a TCU (Transmission Control Unit).

In a preferred embodiment, the manual control shaft and the moving block are coupled through a coupler, and the coupler is inserted into a shaft hole opened in the center of the moving block.

In a preferred embodiment, the rolling contact inhibitor switch accommodates the moving block in a receiving space forming a turning radius of the moving contactor, and the terminal, which is in rolling contact with the moving contactor, An arrayed housing; And a cover coupled with the housing to block the accommodation space from the outside.

In a preferred embodiment, the housing is bolted to the transmission case. The cover is made of a plastic material.

In the present invention, the rolling contact inhibitor switch has the following advantages and effects as compared with the conventional axial contact inhibitor switch.

First, rolling contact between the moving contactor and the terminal minimizes the wear of the surface silver plating, thereby maximizing durability of the contact performance and reducing the cost by a thin silver plating thickness. Secondly, while the moving contact is rotated in a state where it is in contact with the terminal parallel to the axial direction, the travel distance with the terminal is the same, and in particular, the contact radius between the contact roller and the contact guide of the moving contactor is smaller than the contact radius with the terminal There is almost no wear caused by friction during running due to rolling contact with the roller. Third, since the cover is not subjected to the force, it is possible to apply the plastic material instead of the aluminum material, thereby reducing the cost. Fourth, since the cover assembly does not affect the contact performance between the moving contactor and the terminal, the quality can be improved by easy quality control of the inhibitor switch. Fifth, the contact guide of the moving contactor can prevent the contact force imbalance with the terminal by pressing the center portion of the contact roller. Seventh, when the manual control shaft is assembled under the force of the parking detent spring, the operating force is increased when bolts are fastened to the housing and the transmission case, and the external force applied to the moving contactor is easily prevented by the coupler associated with the moving contactor . Eighth, the use of a long spring in the circumferential direction of the moving block makes it easy to implement robustness by reducing the change in contact force against the change in spring length.

2 is a detailed configuration of a moving block and a moving contactor of a rolling contact inhibitor switch according to the present invention, and Fig. 3 is a view showing a detailed structure of a rolling contact inhibitor switch according to the present invention 4 is a state in which the spring-loaded spring force of the rolling contact inhibitor switch according to the present invention is in the Fside side, and Fig. 5 is a view showing the state of the rolling contact inhibitor switch according to the present invention, 6 is a configuration diagram of a conventional down-pressure inhibitor switch according to the related art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The present invention is not limited to these embodiments.

Fig. 1 shows a configuration of a rolling contact inhibitor switch according to the present embodiment. As shown in the figure, the rolling contact inhibitor switch 1 includes a manual control shaft 10, a moving block 20, a coupler 20-1, a moving contactor 30, a terminal 40, a housing 50 ), And a cover 60.

For example, the manual control shaft 10 is fixed to the moving block 20 through the coupler 20-1.

For example, the moving block 20 is coupled to the manual control shaft 10 via a coupler 20-1 provided at the center, and the moving contactor 30 is incorporated in the moving block 20, And the terminal 40 is arranged on the wall surface of the housing 50 and is kept in contact with the moving contactor 30. Particularly, the moving block 20 can arrange the moving contactor 30 in the circumferential direction, so that the moving contactor 30 can form a spring force in the circumferential direction.

For example, the housing 50 defines an internal space for receiving the moving block 20, the coupler 20-1, the moving contactor 30, and the terminal 40 as internal components, Are arranged as inner walls of the inner space to form vertical terminals. The cover 60 is fitted to surround the upper portion of the housing 50 and is coupled with the housing 50 to block external exposure of the internal component.

2 and 3 show the detailed structure of the terminal 40 provided in the moving block 20, the moving contactor 30 and the housing 50, respectively.

Referring to FIG. 2, in one moving block 20, the moving contactor 30 is arranged in four first, second, third, and fourth moving contactors so that the contact of the terminal 40 is uniform . For example, the arrangement angle for each of the first, second, third and fourth moving contactors is equal to 90 degrees, but the arrangement angle may not be uniform if necessary. In particular, the moving contactor 30 may be arranged in three, two, three, or two moving contactors, Can be changed to the accuracy of electrical contact.

The moving block 20 is composed of a cylindrical block body 23 and a concentric body 21 concentric with the inside of the block body 23 is formed at the center of the block body 23 in the block body 23 As shown in Fig. Particularly, in the center of the concentric body 21, a shaft hole 21-1 for inserting a coupler 20-1 having a long hole is formed in a rectangular shape. In this case, the sliding groove 23-1 is formed in a shape of a rectangular parallelepiped shape in the circumferential direction of the block body 23. In this case, A total of four sliding grooves are formed.

Specifically, the moving contactor 30 is composed of a contact roller 31, a contact guide 33, and a spring 35. The contact roller 31 has a contact radius smaller than the contact radius with the terminal 40 so that the contact roller 31 and the terminal 40 are in rolling contact with each other while the contact roller 31 The contact guide 33 can make frictional contact.

For example, the contact roller 31 is formed as a pair of upper and lower rollers 31-3 and 31-5 integrally formed with a roller shaft 31-1 acting as a rotary shaft during free rotation, Each of the upper roller 31-3 and the lower roller 31-5 is formed concentrically with the roller shaft 31-1.

For example, the contact guide 33 is formed in a rectangular shape and is received in the sliding groove 23-1, and the coupling end 33-1 is provided in a trident shape on one side so that the contact roller 31 is freely rotated And the spring 35 is accommodated by providing the spring groove 33-2 in a circular shape on the opposite side. Particularly, a concave groove is formed in the trident shape end of the coupling end 33-1 so that the upper and lower rollers 31-3 and 31-5 are held by the terminal 40 The contact roller 31 can freely rotate. In addition, the middle portion of the trident shape of the coupling end 33-1 is formed longer than both the left and right portions, so that the contact guide 33 presses the central portion of the contact roller 31 to make contact force imbalance between the terminals 40 . As a result, since the contact roller 30 rotates in contact with the terminal 40 in parallel with the axial direction, it is possible to maximize the durability by minimizing the occurrence of abrasion due to friction at the time of travel while the travel distance of the contact terminal is the same, 30 and the surface of the terminal 40 can be minimized and the silver plating thickness can be made thinner.

For example, the spring 35 is inserted into the spring groove 33-2 and integrated with the contact guide 33, and the contact guide 33 is inserted into the sliding groove 23-1 to be integrated with the moving block 20 , A circumferential spring force Fside that pushes the contact roller 31 toward the terminal 40 is formed. Particularly, since the spring 35 is mounted horizontally in the circumferential direction and the long spring can be applied, the change in the contact force against the change in length can be reduced, and thus it is easy to strengthen the spring.

3, the terminal 40 is composed of upper and lower terminals 41 and 42, and the upper terminal 41 and the lower terminal 42 are connected to a receiving space 50-1 so as to be arranged in a vertical terminal. In particular, the upper and lower terminals 41 and 42 are merely examples, and the structure and shape of a terminal applied to a general inhibitor switch can be applied as it is.

4 shows the assembled state of the rolling contact inhibitor switch 1 and the operating state of the spring-loaded spring in the circumferential direction.

As shown in the figure, the manual control shaft 10 is fixed to the moving block 20 through the coupler 20-1, and is rotated by the operation of a cable-connected shift lever, thereby rotating the moving block 20. [ Particularly, the coupler 20-1 is assembled in a state in which the manual control shaft 10 is subjected to the force by the parking detent spring, thereby preventing the external force received by the moving block 20 from rising and the operation force at the time of bolt fastening. The moving block 20 arranges the moving contactor 30 in the circumferential direction so that the moving contactor 30 forms a spring force Fside in the circumferential direction. Therefore, when the moving block 20 is rotated by the manual control shaft 10, the moving contactor 30 is rotated together with the moving block 20 so that the moving contactor 30 The ON / OFF signal pattern for each gear position in accordance with the shift lever operation is formed by the change of the contact position.

The housing 50 includes at least two bolt flanges for bolt-tightening with the transmission case, and an output terminal for externally outputting an electric signal generated at the terminal 40 (see FIGS. 1 and 3). The cover 60 is fitted to surround the upper portion of the housing 50 and is coupled with the housing 50 to block external exposure of the internal component. Particularly, since the cover 60 is constructed so as not to receive a force in a state of being coupled with the housing 50, it is possible to apply the plastic cover, and the quality of the cover can be easily controlled since the cover assembly does not affect the contact performance.

5 shows an example of a contact switching circuit for each shift position of the rolling contact inhibitor switch 1 according to the present invention.

As shown in the figure, the contact switching circuit is formed by a change in the contact state between the moving contactor 30 and the terminal 40 due to the rotation of the moving block 20, and is connected to an electrical circuit (TCU) And a contact switch 70 which forms a contact switch 70. Here, the contact switch 70 is divided into four S1, S2, S3, and S4 in total, which is connected to P-R-N-D, which illustrates a conventional contact switch configuration of the inhibitor switch 1. [

Therefore, when the moving block 20 of the habit position 1 is rotated in accordance with the rotation of the manual control shaft 10, the moving contactor 30 rotates according to the rotation of the moving block 20, S1, S2, S3, and S4 of the contact switch 70 that are pulled down to the GND are switched on according to the contact state, thereby making the ON / OFF signal pattern by contacting the terminal 40 at a specific angle. A voltage (12V) signal is input to the TCU 80. At this time, if a signal other than the input pattern is held for 4 seconds or more, it is judged as a failure.

As described above, the rolling contact inhibitor switch according to the present embodiment includes a moving block 20 in which a manual control shaft 10 connected to a shift lever passes through a center and acts as a rotating shaft, A terminal for forming a transmission ON / OFF signal pattern by a rotation angle change of the moving contactor 30 in a rolling contact state with the moving contactor 30; A housing 50 in which the moving block 20 is housed in a receiving space 50-1 having an inner wall in which a terminal 40 is arranged and a cover 60 coupled with the housing 50, The contact between the moving contactor 30 and the terminal 40 is minimized by the rolling contact between the moving contactor 30 and the terminal 40 for switching the contact point signal, So that the contact performance is maintained firmly.
