Background technique
DE 195 42 726 A1 disclose a kind of cone ring transmission, and wherein, the cone friction wheel that oppositely is provided with is contained on the parallel axle each other.By friction wheel axle axially on move velocity ratio that can the step-less adjustment cone ring transmission.
Outer contacting rotating, outside work that friction ring on the cone ring transmission has inner contact surface surperficial and rotating, that radially inwardly work.Inner contact surface this with by friction ring around the contact surface of cone friction wheel constitute first contact area, this contact surface of cone friction wheel is the conical outer surface of cone friction wheel.Second contact area be in the outer contacting surface of friction ring and cone friction wheel can't help friction ring around contact surface between.Because friction ring clamps between two opposed cone friction wheels, so torque can be transmitted between two cone friction wheels by first and second contact areas by it.
For transmitting torque between revolving part (cone friction wheel and friction ring), use suitable friction drive liquid usually, should be separately by it with the obedient each other contact surface that leans in the contact area.If thisly separately produce, then carry out in the gap that the shearing stress of the transmission of torque by friction drive liquid produces between the revolving part that participates in by friction drive liquid.If torque is successfully transmitted by the shearing of friction drive liquid purely, then can avoid being generally the abrasive wear of the contact surface of metal ideally fully.Be the effective connection between the revolving part that designs two non-conformalities, can use the theory of elastohydrodynamics.
Because velocity ratio can steplessly change, on automobile, use cone ring transmission to have lot of advantages.Like this by stepless speed variator can the optimum utilization internal-combustion engine torque conditions and efficient.Can also have the physical dimension of speed changer by the peak torque of speed changer transmission, loss in the speed changer is a crucial factor in this regard, and they interdepend, and part is opposite and therefore makes the design of the cone ring transmission difficulty that becomes.For example, though can cause lowering efficiency by strengthening the impacting force raising peak torque between friction ring and the cone friction wheel, doing like this, and, do not separate as long as reach completely between the revolving part that participates in, also can cause the wearing and tearing in the speed changer to increase by friction drive liquid.
Summary of the invention
Therefore purpose of the present invention is that a kind of cone ring transmission is provided, and it can not have transfer high torque under the situation that efficient is high as far as possible of wearing and tearing as far as possible.
This purpose utilizes the feature of claim 1 to be achieved according to the present invention.The preferred embodiments of the present invention are consulted dependent claims.
Cone ring transmission of the present invention is characterised in that at least one contact surface of the contact surface of at least one cone friction wheel and/or friction ring has the traverse furrow groove, and they extend transverse to the sense of rotation of cone friction wheel or friction ring with certain angle.Therefore can make all contact surfaces of cone ring transmission according to the present invention, just the contact surface of two cone friction wheels and the outer contacting surface and the inner contact surface of friction ring are provided with the traverse furrow groove.Can have the traverse furrow groove by only single contact surface: for example can make the conical outer surface that uses as contact surface of a cone friction wheel only have traverse furrow groove transverse to sense of rotation, friction ring and another cone friction wheel then do not have this traverse furrow groove yet.Also can stipulate, only the outer contacting of friction ring surface or only the inner contact surface of friction ring have according to traverse furrow groove of the present invention.
Notion " traverse furrow groove " be interpreted as on the contact surface at vertical upwardly extending those recesses.Should be vertically with respect to the sense of rotation of the revolving part (cone friction wheel or friction ring) that when cone ring transmission work, rotates with an angle around its spin axis, according to preferred embodiment, this angle is 90 °.But also can be to be not equal to 90 ° angle.For example the traverse furrow groove can have the angle of 30 °, 45 ° or 60 ° with respect to sense of rotation.
Can under the given situation of the extruding force between the revolving part, improve the pressure of the friction drive liquid that is in the there by the traverse furrow groove on the contact surface that is preferably metal.For friction drive liquid, pressure raises and causes viscosity to increase usually, thereby friction drive liquid can absorb bigger shearing stress.Because shearing stress improves, therefore can transmit higher torque by friction drive liquid.
These traverse furrow grooves can be divided into first group of traverse furrow groove and second group of traverse furrow groove, and wherein, the traverse furrow groove can be straight or also can be crooked.Key be the traverse furrow groove at least in the zone of contact area under certain angle transverse to the sense of rotation extension of the revolving part of correspondence.
At least one contact surface of the contact surface of at least one cone friction wheel and/or friction ring can have the groove that extends on sense of rotation.Groove and traverse furrow groove form grid at this on the contact surface of corresponding rotation part.
In a preferred embodiment, contact surface has high desk-top surface structure.The desk-top surface structure of this height for example can be realized thus: the dimpling point that will produce by the cutting of contact surface is removed by suitable method.The miniature ditch that cutting by contact surface produces or little groove obtain keeping when removing the dimpling point, wherein, constitute the zone or the high platform that scabble between two adjacent grooves.
If contact surface has the groove that extends on sense of rotation and transverse to this traverse furrow groove, then one high by two adjacent grooves and two adjacent traverse furrow groove limited boundaries.Thus according to traverse furrow groove and the different formation rectangles of angle between the groove or the high platform of parallelogram.Process under the situation on the contact surface with the angle different with respect to sense of rotation at the traverse furrow groove, high platform also can be triangle.
By the desk-top surface structure of height, the film height of the friction drive liquid in the contact area between two contact surfaces against each other can reduce, and wherein, the contact between the contact surface keeps clearly separating.Can produce higher pressure by reducing in the film high friction transmission fluid, improving thus can be by the shearing stress of friction drive liquid absorption.
The basic roughness of cone friction wheel contact surface cone friction wheel axially on can change.For example, the average space of the groove on the sense of rotation and/or mean depth can be adjusted targetedly, so that change the carrying ratio and therefore change compressive load per unit area according to the axial position of velocity ratio or friction ring.The basic roughness that changes on the sense of rotation for example can realize by the feed speed that changes machining tool relatively with axial position.
The invention still further relates to a kind of method, be used to process the contact surface of the friction ring of using according to the described cone ring transmission of one of claim 1 to 8.The method is characterized in that, when ring axis rotates, the traverse furrow groove is worked on inner contact surface and/or the outer contacting surface by brush at friction ring around the rotation of brush axis by a brush or similar device, wherein, between the ring axis of friction ring and brush axis, enclose at an angle.At this, make the traverse furrow groove by brush, they with respect to the sense of rotation of friction ring with an angle, this angle dependence in the rotational speed of the rotational speed of friction ring, brush and the spin axis of friction ring with brush the angle that surrounds between the axis.The traverse furrow groove also can be worked on the contact surface of cone friction wheel in a similar manner.
In the method according to the invention, preferably can be removing the dimpling point on the contact surface of friction ring and/or on the contact surface at least one cone friction wheel, to obtain to improve the high desk-top surface structure of carrying ratio.

Embodiment
Fig. 1 illustrates the cone ring transmission of an integral body with 1 mark.Cone ring transmission 1 has one first cone friction wheel 2 and one second cone friction wheel 3.Cone friction wheel 2,3 oppositely is provided with each other, wherein, and the parallel distribution of their spin axis and the distance that separates each other.The spin axis of cone friction wheel 2,34,5 illustrates by a dotted line.
Except cone ring transmission 1, Fig. 1 also illustrates the clutch 6 of an automobile that does not further illustrate here.Clutch 6 is not connected with first cone friction wheel 2 by axle 7 with relatively rotating.Clutch 6 is delivered to torque on first cone friction wheel 2 by axle under closed state.For torque is delivered on second cone friction wheel 3 from first cone friction wheel 2, be provided with a friction ring 8, it acts on two cone friction wheels 2,3 and mutually around first cone friction wheel 2.Friction ring 8 can move axially abreast by the spin axis 4,5 of a controlling mechanism that does not illustrate here and cone friction wheel 2,3.The velocity ratio of regulating cone ring transmission 1 that moves axially by friction ring 8.Because the axial position of friction ring 8 can step-less adjustment, so cone ring transmission 1 has the infinitely variable velocity ratio.
Be delivered on second cone friction wheel 3 torque by one by gear 9 and with gear mesh that the ring gear 10 of this gear 9 engagements the is formed output unit 11 that leads.Output unit 11 is made up of a differential mechanism 11a and two axle 11b, 11c.Differential mechanism 11a will act on torque distribution on the gear 10 on axle 11b, 11c.On the cone ring transmission shown in Fig. 11, first cone friction wheel 2 can be called wheel for inputting and second cone friction wheel 3 is called output wheel corresponding to torque flow.
As appreciable from Fig. 1, inner contact surface abuts on the outer surface 16 of cone friction wheel 2 in a contact area 17.When cone ring transmission 1 work, form the narrow film of friction drive liquid in the contact area 17, thereby the inner contact surface 12 of the contact surface 16 of cone friction wheel 2 and friction ring 8 is separated from each other by friction drive liquid and not directly roll extrusion mutually.Because high pressure and the consequent high viscosity of friction drive liquid contact area 17 in, friction drive liquid based on can by the shearing stress of friction drive liquid absorption with the transmission of torque of cone friction wheel 2 to friction ring 8.
Corresponding with first contact area 17, second contact area 18 produces between the outer contacting surface 13 of contact surface 19 and friction ring 8, and this contact surface 19 is conical outer surfaces of cone friction wheel 3.During cone ring transmission 1 work, in second contact area 18, between contact surface 13 and contact surface 19, also form the film of friction drive liquid, thereby two facing surfaces also are separated from each other here.Torque is here also ideally only by the friction drive liquid transmission.
Fig. 2 illustrates a section 20 of the inner contact surface 12 of friction ring 8.This is a circular piece that reclines with it above section 20, a section of the contact surface 16 of its expression cone friction wheel 2.Do not see the tapering of section 20,21 from Fig. 2, but section 21 is illustrated as cylindrical body with the section 20 of the inner contact surface 12 of friction ring 8 plate as the plane.Therefore Fig. 2 does not illustrate the curvature of annular contact surface 12 equally.
