New energy electric axle

Abstract

The invention relates to the technical field of motor vehicle axles, in particular to a new energy electric axle. The new energy electric axle comprises an axle main shaft, a brake disc is fixedly connected to one side of the axle main shaft, an axle shell is movably connected to the outer surface of the axle main shaft through a bearing, a brake caliper support is fixedly connected to the right end of the side, close to the brake disc, of the axle shell, and two sliding pins are symmetrically and fixedly connected to the upper end and the lower end of the outer surface of the rear end of the brake caliper support. According to the new energy electric axle, a friction mechanism is arranged, and a friction plate and the brake disc make contact with each other, so that the purpose of decelerating a vehicle is achieved; and the vehicle is braked emergently through a front brake pad and a rear brake pad, due to the fact that the front brake pad and the rear brake pad do not make contact with the brake disc when the vehicle is decelerated, the front brake pad and the rear brake pad are protected, the replacement frequency of the front brake pad and the rear brake pad is reduced, the use cost is reduced for a user, and meanwhile the maintenance time of an operator is shortened.

Description

technical field [0001] The invention relates to the technical field of motor vehicle axles, in particular to a new energy electric axle. Background technique [0002] The automobile axle (also known as the axle) is connected to the frame (or load-bearing body) through the suspension, and the wheels are installed at both ends. The role of the axle is to bear the load of the car and maintain the normal driving of the car on the road. The axle can be integral, like a huge barbell, and the two ends support the body through the suspension system, so the integral axle usually cooperates with the non-independent suspension; the axle can also be disconnected, like two Umbrellas are inserted on both sides of the vehicle body, and then each supports the vehicle body through the suspension system, so the disconnected axle is used with the independent suspension; [0003] A good braking system is the key factor to determine driving safety. At present, the braking system of motor vehic...

Problems solved by technology

[0005] The above comparative patents increase the contact area with the brake pads during braking by setting the upper brake caliper and the lower brake caliper, increase the braking efficiency and reduce the braking distance , improve the braking performance, thereby increasing the safety of the vehicle, but because the vehicle braking system relies on the huge friction generated by the mutual fit of the brake disc and the brake pad to stop the brake disc from rotating, so as to achieve the purpose of vehicle braking, Brake discs and brake pads will wear due to friction. In order to ensure the normal operation of the braking system, the brake discs and brake pads need to be replaced regularly, which increases the cost of use. Compared with brake discs, brake pads are more prone to wear , the replacement frequency is higher, which increases the user's use cost and increases the operator's maintenance time
