Abstract

A hydraulic coupling type limited-slip differential has two gear functions, i.e. a common gear differential gear and a hydraulic coupler differential gear. The hydraulic coupling type limited-slip differential is in the common gear differential gear in a usual state, can develop the high efficiency of the common gear differential gear to carry out transmission under a better road condition and can shift gears under a poorer road condition so that the hydraulic coupler type limited-slip differential is in a work state of the transmission of a hydraulic coupler differential, thereby a transmission shaft can distribute more torques to a half shaft with a larger drag torque according to the torsion conditions of two half shafts; and in addition, the invention enhances the passing ability of an automobile by driving the automobile to go forwards.

Description

Hydraulic coupler type limited-slip differential
Technical field
The present invention relates to a kind of diff, be applicable to automobile and other equipment.
Background technology
The ordinary gear diff that uses on the present various automobile can not be applicable to special road surface, promptly when monolateral tyre skidding, the wheel that makes other one side can not be obtained propulsive effort and automobile can not be advanced, and the crossing ability of automobile is bad; For existing various anti-skid final drives, ubiquity complicated operation, occur easily single semiaxis bear excessive machine torque and damage semiaxis and two-semiaxle can not relatively rotate and make automobile turn to defectives such as difficulty.
Cross-country car and the goods carrying vehicle and the part passenger vehicle that travel under the relatively poor road conditions, urgent especially for the demand of High Performance anti-skid final drive.
Summary of the invention
The object of the invention is to provide a kind of anti-skid final drive of hydraulic coupler type, when running car during in different road conditions, can change the mode of operation of diff as required, adapts to different road conditions.
The present invention adopts hydraulic coupler type transmission of torque mode, when relatively poor road conditions, use the anti-skidding shelves of this diff, the torque that can distribute transmission shaft according to the required torque situation of wheel, improve the crossing ability of vehicle, when satisfying skid-resistance requirements, can avoid the serious overload of semiaxis and the damage semiaxis; When road conditions condition preferably, can switch to common shelves, use the ordinary gear diff, thereby make vehicle obtain very high transmission of torque efficient, improve the road mobility of automobile.
In sum, advantage of the present invention has:
1. this diff has two kinds of mode of operations, and a kind of is the ordinary gear diff that uses on road surface preferably, can obtain good transmission of torque efficient; A kind of is the hydraulic coupler type diff that uses on relatively poor road surface, can improve the crossing ability of automobile according to the needs distribution of torque of wheel.
2. this diff has utilized the advantage of hydraulic transmission: flexible transmission.When using fluid power differential shelves, can not damage driving system because of mechanical vibration and enforceable transmission of torque, give two-semiaxle with certain feedback transmission space, increased the efficient and the alerting ability of transmission.
3. the easy switching between two grades of this difies does not need to stop and just can realize.
4. the manufacturing of this diff is simple, and each part is gauge member, and cost is low.Because be a kind of knockdown structure, thus can reequip upgrading to existing ordinary gear diff easily, and the volume of whole diff is less.

Fig. 2 is hydraulic coupler differential shelves work structuring figure of the present invention.
Fig. 3 is a hydraulic coupler shaft coupling constructional drawing of the present invention.
Among Fig. 1: 1. right axle shaft, 2. left half axle, 3. transmission shaft, 4. gear shift slide block, 5. left half axle finishing bevel gear cuter, 6. right axle shaft finishing bevel gear cuter, 7. shaft gear, 8,9. turbine finishing bevel gear cuter, 10,11. pump impeller gears, 12,13. hydraulic couplers.
The specific embodiment
Below in conjunction with diagram 26S Proteasome Structure and Function of the present invention is illustrated
Referring to Fig. 1, left half axle (2), right axle shaft (1) and transmission shaft (3) constitute the ordinary gear diff.
On left half axle (2), fix finishing bevel gear cuter (5), on right axle shaft (1), fixing finishing bevel gear cuter (6), on transmission shaft (3), fixing gear (7).
The hydraulic coupler shaft coupling is connected with car body by bearing, makes it under normal conditions by retracing spring, finishing bevel gear cuter (5) and finishing bevel gear cuter (9), finishing bevel gear cuter (6) and finishing bevel gear cuter (8) jump out of mesh, gear (7) and gear (10), (11) jump out of mesh.
Gear shift slide block (4) promotes the hydraulic coupler shaft coupling by gear shift action, makes finishing bevel gear cuter (5) and finishing bevel gear cuter (9), finishing bevel gear cuter (6) and finishing bevel gear cuter (8), and gear (7) and gear (10), (11) enter engagement simultaneously.Enter fluid power differential shelves.
Return when gear shift slide block (4), the hydraulic coupler shaft coupling is return the home position under the effect of retracing spring, and automobile changes to ordinary gear differential shelves.

Claims (5)

1, a kind of hydraulic coupler type limited-slip differential comprises left half axle (2), and right axle shaft (1) and transmission shaft (3) constitute the ordinary gear diff; Comprise the hydraulic coupler shaft coupling, gear shift slide block (4), left half axle finishing bevel gear cuter (5), right axle shaft finishing bevel gear cuter (6), shaft gear (7), turbine finishing bevel gear cuter (8), (9), pump impeller gear (10), (11), hydraulic coupler (12), (13).
2, hydraulic coupler type limited-slip differential as claimed in claim 1, it is characterized in that: under normal circumstances, this diff is in ordinary gear diff gear, under road conditions preferably, can bring into play the high-efficiency characteristics of ordinary gear diff and carry out transmission.At this moment, retracing spring promotes the hydraulic coupler shaft coupling, and finishing bevel gear cuter (6) does not mesh with finishing bevel gear cuter (8), and finishing bevel gear cuter (5) does not mesh with finishing bevel gear cuter (9), and gear (7) does not mesh with gear (10) and gear (11).
