Abstract
The utility model discloses a hub speed-reduction drive axle which comprises a hub speed reducer, a wheel hub, a brake air chamber and a disc-type brake, wherein the disc-type brake comprises a brake caliper and a brake disc; the first side of the wheel hub is connected with the hub speed reducer; the second side of the wheel hub is connected with the brake disc; and the brake air chamber is connected with the brake caliper so as to clamp the brake disc selectively. Because the disc-type brake is configured, the thermal stability and water stability of the brake are enhanced, the brake torque is improved, and the reliability and safety of a vehicle are improved.
Description
Technical field
The utility model relates to a kind of automobile drive axle, relates in particular to a kind of hub reduction drive axle that comprises plate disc brake.
Background technology
Be equipped with the hub reduction drive axle in, the heavy type commercial vehicle is widely used in engineering construction and logistics transportation, traffic safety receives extensive concern.Wherein, the performance of brake system is to weigh the important indicator of safety performance.Present stage: in, employed hub reduction drive axle adopts drum brake more in the heavy type commercial vehicle.The drum brake mechanism own characteristic has determined that under specific operation and environment, the deceleration and stopping performance of car load can descend to some extent, can't satisfy the requirement of safe driving.
The utility model content
In view of the deficiency of above-mentioned technology, the utility model aims to provide a kind of hub reduction drive axle that is equipped with plate disc brake.
The hub reduction drive axle of the utility model comprises: wheel reduction gear, wheel hub, compressed air brake cylinder, plate disc brake; Said plate disc brake comprises brake clamp and brake disc; First side of wheel hub is connected with wheel reduction gear, and second side of wheel hub is connected with brake disc; Compressed air brake cylinder is connected in brake clamp, with clamping brake disc selectively.
Preferably, outer form is partially adopted in the installation of compressed air brake cylinder, and outer drift angle is 3 °-15 °.
Preferably, said wheel hub is equipped with unit bearing, and the internal diameter of said unit bearing is Φ 100mm-Φ 110mm.
Preferably, the reduction ratio of said wheel reduction gear is 3-4.
Owing to disposed plate disc brake, strengthen heat stability, water stability, the raising lock torque of drg, promote the reliability and the safety of vehicle.
