A cylinder roller (9) can be added among the non-cylinder wedge clutch particles (3), a clutch particle separator (10) can be equipped between the exterior circular level of the spline housing (6) and the interior circular level of the nosing (2), and a non-cylinder wedge clutch particle (3) is arranged in the clutch particle separator (10). The utility model realizes the freewheeling clutch between the spine housing (6) and the nosing (2), transports relatively large torque under the conditions of limited radial size and bears relatively high freewheeling revolution speed, thereby being suitable for industrial volume-production.
Description
Technical field:
The utility model relates to clutch driven disk for automobile manufacturing technology field, especially a kind of automobile semi-automatic free wheel device driven disc of wedge block type.
Background technique:
The clutch driven plate that existing automobile is used from vehicle starting, parking or gear shift, all wants stepping on clutch just can finish, and has so not only increased machine members and impact, also makes driver's complicated operationization, and labor intensity is big.For this reason, the patent documentation that name is called unilateral bearing check free wheel device driven disc (patent No. ZL00212283.9) discloses the improvement design of a kind of automobile with clutch driven plate, the spline bead of automobile clutch is resolved into spline housing and two parts of bead, circular roller clutch dog and supported spring are housed between the two, the surface of contact of circular roller clutch dog and bead is a curved surface, make the spline bead become a free wheel device, make automobile not need stepping on clutch just can realize mechanical gear shift under steam, thereby reduce the programmed sequence of operations of driver, increased the working life of clutch system simultaneously.Be called all to have adopted in the patent documentation of a kind of automobile with clutch driven plate (patent No. ZL02241019.8) and clutch driven disk for automobile (patent No. ZL03208639.3) in name and on spline housing outer surface or bead internal surface, process a radius increasing or decreasing curved surface, and the method for the cylindrical rollers of packing into therein realizes the overdrive clutch function, and clutch dog is a cylindrical body.These several patents all have advantage separately, but its common shortcoming is: under the same radial dimension situation, the clutch dog number that can pack into is less, and the clutch dog contact radius is less, so bearing capacity is low; The high-speed slide friction can be produced between spring and the clutch dog, the higher speed that surmounts can't be born, so limit speed is low.
The model utility content:
In order to solve the problem of above-mentioned existence, the purpose of this utility model provides a kind of automobile semi-automatic free wheel device driven disc of wedge block type, and to be implemented under the limited radial dimension situation, transfer larger torque is born the higher rotating speed that surmounts.
The utility model is to adopt following technological scheme to realize: a kind of automobile semi-automatic free wheel device driven disc of wedge block type, comprise pressure spring plate, friction plate, damping spring, spline housing, bead up and down, between the periphery of described spline housing and the inner headed face of bead non-cylindrical voussoir clutch dog and preloading spring are housed.
Between described non-cylindrical voussoir clutch dog, be provided with cylindrical rollers.
Between described spline housing periphery and bead inner headed face, the clutch dog separator is set, the non-cylindrical voussoir clutch dog of in the clutch dog separator, packing into.
The obtained effect of the utility model is as follows: because the utility model allows the more non-cylindrical voussoir clutch dog of along the circumferential direction packing in the gap between spline housing and bead, so under the comparable size situation, can realize the transmission than high pulling torque; Because of this clutch dog is a non-cylindrical voussoir clutch dog, clutch dog is bigger than cylindrical clutch dog with the contact radius of spline housing and bead contacting point, so can reduce contact stress, improves the life-span; No matter spline housing and bead are surmounting or bonding state, and non-cylindrical voussoir clutch dog has only revolution, does not have rotation, and the revolution rotating speed is lower, thereby can bear the higher speed that surmounts; Because spline housing outer surface and bead internal surface are the cylndrical surface, easy to process, cost is low, is suitable for industrialized mass.

Embodiment:
Embodiment 1:
In Fig. 1,2,5, up and down pressure spring plate of the present utility model 7 links together by rivet, link to each other with friction plate 1 by spring sheet 8 then, in pressure spring plate 7 corresponding four spring grooves several damping springs 4 are housed jointly up and down, the spline bead that spline housing 6 and bead 2 constitute is up and down between the pressure spring plate 7, non-cylindrical voussoir clutch dog 3 is housed between the inner headed face of the periphery of spline housing 6 and bead 2, and with spring 5 pretensions, to realize the overdrive clutch between spline housing 6 and the bead 2.Spline housing 6 and bead 2 are the cylndrical surface with the contacting point of non-cylindrical voussoir clutch dog 3.
The utility model is work like this: when automobile is desired the conversion gear under steam, without stepping on clutch, unclamp throttle, the bead 2 and the engine crankshaft of driven disc rotate synchronously, its rotating speed is less than spline housing 6 rotating speeds synchronous with the gearbox input shaft, pressure angle between spline housing 6 and the non-cylindrical voussoir clutch dog 3 is greater than friction angle, be in separated state between spline housing 6 and the non-cylindrical voussoir clutch dog 3, thereby make spline housing 6 and bead 2 be in separated state, clutch is realized separating automatically, and this moment can light free conversion gear.After the gear shift if will improve the speed of a motor vehicle, directly step on the gas this moment, engine speed improves gradually, when engine speed reaches spline housing 6 rotating speeds, because the pressure angle between spline housing 6 and the non-cylindrical voussoir clutch dog 3 is less than friction angle at this moment, spline housing 6 enters bonding state with bead 2 automatically by non-cylindrical voussoir clutch dog 3, realizes that engine-driven car quickens, and needn't trample clutch.This shows no matter automobile needs speed change or gear shift, all can not need manually to trample clutch, thereby realizes semi-automatic clutch gearshift.
Embodiment 2:
In order to bear the higher speed that surmounts, can on the basis of the foregoing description, between non-cylindrical voussoir clutch dog 3, add several cylindrical rollers 9, referring to Fig. 3.Cylindrical rollers 9 can play the centering effect between spline housing 6 and bead 2, and can force non-cylindrical voussoir clutch dog 3 to improve revolution speeds, reduces the relative rotation speed of itself and spline housing 6, thereby makes it can bear higher limit speed.Its working principle is identical with the foregoing description 1.
Embodiment 3:
According to the actual conditions of automobile, on the basis of the foregoing description 1, also can between spline housing 6 peripheries and bead 2 inner headed faces, clutch dog separator 10 be set, the non-cylindrical voussoir clutch dog 3 of packing in clutch dog separator 10 is referring to Fig. 4.Its working principle is identical with the foregoing description 1.
