Abstract
A hydraulic coupler type coupling limited slip differential comprises two shift functions: a common gear differential shift and a hydraulic coupler coupling differential shift. In the normal condition, the differential is at the common gear differential shift; in the better road conditions, the differential can bring high efficiency of the common gear differential to drive; in the poor road conditions, the shift can be changed, so that the differential is at the working state of the hydraulic coupler coupling differential drive, therefore, the driving shaft can automatically transmit more torques to a half-shaft with low rotation speed according to the rotation speed of two half-shafts at the transmission characteristic of the hydraulic coupler condition so as to drive the car and improve the trafficability characteristic.
Description
Technical field
The present invention relates to a kind of limited slip differential, be applicable to automobile and other equipment.
Background technique
The ordinary gear differential mechanism that uses on the present various automobile can not be applicable to special road surface, promptly when monolateral wheel-slip, will make the non-slip wheel of another side can not obtain driving force and automobile can not be advanced, and the passing ability of automobile is bad; For existing various limited slip differential, ubiquity operation and processing is comparatively complicated, occur easily single semiaxis bear excessive mandatory machine torque and damage semiaxis and two-semiaxle when Vehicular turn, can not relatively rotate and make automobile turn to defective such as difficulty.
Go-anywhere vehicle and the cargo vehicle and the part passenger vehicle that travel under the relatively poor road conditions, urgent especially for the demand of high-performance limited slip differential.
Summary of the invention
The object of the invention is to provide a kind of limited slip differential of hydraulic coupler type, when automobile running during in different road conditions, can change the mode of operation of differential mechanism as required, adapts to different road conditions.
The present invention adopts hydraulic coupler type coupling limited transmission of torque mode.When relatively poor road conditions, use the anti-skidding shelves of this differential mechanism, the torque that can distribute transmission shaft according to the required torque situation of wheel improves the passing ability of vehicle; Because fluid coupling has flexible transmission, so when satisfying skid-resistance requirements, can avoid the serious overload of semiaxis and the damage semiaxis; When road conditions condition preferably, can switch to the open differential shelves, use the ordinary gear differential mechanism, thereby make car obtain very high transmission of torque efficient, improve the road mobility of automobile.
In sum, advantage of the present invention has:
1. this differential mechanism has two kinds of working staties, and a kind of is the ordinary gear differential shelves that use on road surface preferably, can obtain good transmission of torque efficient; A kind of is the hydraulic coupler type coupling limited differential shelves that use on relatively poor road surface, can be according to the rotating speed of wheel, and distribution of torque flexibly improves the passing ability of automobile.
2. this differential mechanism has utilized the advantage of hydraudynamic drive: flexible transmission.When using fluid coupling shaft coupling differential shelves, can not damage transmission system because of mechanical vibration and enforceable transmission of torque, give two-semiaxle with certain feedback transmission space, improved the efficient and the flexibility of transmission.
3. the easy switching between two grades of this differential mechanisms does not need to stop and just can realize.
4. the manufacturing of this differential mechanism is simple, and each part is standard piece, and cost is low, the fluid coupling volume of small dimension is little, can reequip upgrading to existing open differential easily, directly become coupler type coupling limited slip differential, and the volume of whole differential mechanism is less.

Among Fig. 1: 1. fluid coupling shaft coupling right axle shaft, 2. fluid coupling shaft coupling left half axle, 3. fluid coupling, 4. vehicle bridge left half axle, 5. vehicle bridge right axle shaft, 6. transmission shaft, 7,8,9,10. gear.
Embodiment
Below in conjunction with diagram 26S Proteasome Structure and Function of the present invention is illustrated
Referring to Fig. 1, vehicle bridge left half axle (4), vehicle bridge right axle shaft (5) and transmission shaft (6) constitute the ordinary gear differential mechanism.
Fluid coupling shaft coupling right axle shaft (1), fluid coupling shaft coupling left half axle (2) and fluid coupling (3) constitute the fluid coupling shaft coupling, during two semiaxis work of shaft coupling by gear (9), (10) respectively with axle half shafts on gear (7), (8) mesh and carry out transmission.
Make by gearshift gear (9) on two semiaxis of shaft coupling, (10) respectively with axle half shafts on gear (7), (8) break away from engagement, then differential mechanism works in ordinary gear differential mechanism state, to adapt to road conditions preferably.
Two semiaxis that make shaft coupling by gearshift by gear (9), (10) respectively with axle half shafts on gear (7), (8) engagement, then differential mechanism works in fluid coupling shaft coupling differential state,, wheel relatively poor to adapt to be one-sided road conditions of skidding easily.
