Embodiment
[0031] refer to Figure 1~5 , The differential lock of the present invention includes a differential lock shaft 1 , a gate seat 2 , a bearing fixing seat 3 , a bearing 4 and a housing 5 . The brake seat 2 is cylindrical, which can cooperate with the differential lock shaft 1 , and the housing is also cylindrical, which can cooperate with the bearing holder 3 .
[0032] A symmetrically arranged brake block 7 is connected to the surface of one end of the brake seat 2, and the brake block 7 can rotate around the axis of the end. The brake blocks 7 are connected together by an elastic member 8, and the elastic member 8 is preferably a spring member. One end of the differential lock shaft 1 is provided with a fixed seat 6 , the brake seat 2 is fitted and connected to the differential lock shaft 1 , and one side of the brake block 7 is in clearance fit with the fixed seat 6 . The bearing 4 is arranged in the bearing fixing seat 3, and the bearing 4 is sleeved and connected on the ...

The invention relates to the technical field of driving of automobiles, in particular to a differential lock. The differential lock comprises a differential lock shaft, a cylindrical gate seat, a bearing fixing seat, a bearing and a cylindrical shell, wherein a fixing seat is arranged at one end of the differential lock shaft; symmetric gate blocks are arranged on the surface of the gate seat, are close to an end of the gate seat, are connected with each other together by elastic components arranged along the surface of the gate seat, and can rotate around the axis of the end of the gate seat; the gate seat is connected to the differential lock shaft in a sleeved manner; one sides of the gate blocks are matched with the fixing seat; the other sides of the gate blocks are matched with the bearing which is connected to the gate seat in a sleeved manner; the bearing is arranged in the bearing fixing seat; the bearing fixing seat is arranged in the shell; and ends of the gate blocks are higher than the outer surface of the shell. The differential lock is simple in structure; because friction plates are replaced by the gate blocks, and the gate blocks cannot rub like the friction plates for a long time, are not easy to damage and are not required to be replaced frequently, using cost is reduced.
Description
technical field [0001] The invention relates to the technical field of automobile drive, in particular to a differential lock. Background technique [0002] The power of the car engine is transmitted to the drive axle through the clutch, transmission, drive shaft, and then distributed to the left and right axle drive wheels. In this power transmission path, the drive axle is the last assembly, and its main components are reducer and differential. [0003] Ordinary differentials are composed of planetary gears, planetary gear carriers (differential case), side gears and other parts. The power of the engine enters the differential through the transmission shaft, directly drives the planetary gear carrier, and then the planetary gear drives the left and right half shafts to drive the left and right wheels respectively. When the car is going straight, the speeds of the left and right wheels and the planetary wheel carrier are equal and in a balanced state, but when the car tur...
