Embodiment Construction
[0016] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.
[0017] See figure 1 and figure 2 As shown, the electromagnetically controlled anti-skid device A for light truck drive wheels in this embodiment includes an electromagnetic coil cone sleeve 3 , an electromagnetic coil 4 , a damping sleeve 5 , a spring leaf 6 and an inner cone friction ring 7 . The electromagnetically controlled anti-skid device A for light truck drive wheels is connected between the differential 1 and the wheels 2 on both sides, that is, one wheel 2 corresponds to one anti-skid device A for electromagnetically controlled light truck drive wheels. The specific structure is such that an inner cylindrical groove 8a is provided on the inner side of the drive axle housing 8 between the differential 1 and the wheel 2, and the outer cylindrical surface of the electromagnetic coil cone sleeve 3 cooperates with the inner c...

The invention discloses an electromagnetic-controlled light truck driving wheel anti-skid device which is connected between a differential and wheels, and comprises an electromagnetic coil cone sleeve, an electromagnetic coil, a damping sleeve, a spring sheet and an inner cone friction ring. The electromagnetic coil cone sleeve is fixedly arranged on the inner side of a drive axle housing and is provided with a central through hole for penetrating a drive shaft, the electromagnetic coil is arranged on one side of the electromagnetic coil cone sleeve, a friction conical convex boss is arrangedon the other side of the electromagnetic coil cone sleeve in an enclosing manner, the damping sleeve is connected to the drive shaft through a retaining ring and a spline, and is positioned on one side of the electromagnetic coil cone sleeve, the inner cone friction ring sleeves the damping sleeve and slidably cooperates with the damping sleeve, the end, facing the friction conical convex boss, ofthe inner cone friction ring is provided with a conical opening matched with the outer conical surface of the friction conical convex boss, and the other end of the inner cone friction ring is connected with the damping sleeve through the spring sheet. The device increases the torque of the drive shaft on the slipping side through the friction between the inner cone friction ring and the electromagnetic coil cone sleeve, so that the drive shaft on the other side obtains a larger torque, and the automobile can run normally.
Description
technical field [0001] The invention relates to a driving wheel anti-skid device, in particular to an electromagnetically controlled light truck driving wheel anti-skid device. Background technique [0002] The internal friction torque of the symmetrical bevel gear differential in the light truck drive axle is very small, its locking coefficient K=0.05-0.15; torque ratio Kb=1.1-1.4. Therefore, regardless of the differential speed or not, the ordinary planetary gear differential has the characteristics of equal torque distribution. The equal distribution characteristic of ordinary differential gear is very unfavorable when the car is driving on the road with poor road conditions. Because one wheel slips, the resulting torque is very small, while the other wheel can only be distributed to get a small torque. It is difficult for the car to leave the road. [0003] In order to improve the passing ability of cars on slippery roads, anti-skid differentials are installed on some ...
