Problems solved by technology

The radial size of the outer ball of the steering knuckle of the steering drive front axle of the car is not less than 180mm. If the air brake is used, the center distance between the camshaft and the wheel axle is generally 120mm, and the outer diameter of the position where the camshaft is installed on the air brake seat is about 70mm. Interference will occur, resulting in failure to install
Therefore, people can only use hydraulic brakes with poor braking effect.

Abstract

The invention discloses a braking mechanism of an automobile steering driving front axle, comprising a brake, an air brake seat, a brake adjusting arm, an air chamber and a cam shaft. The brake is provided with a brake soleplate which is provided with a cam shaft mounting hole; the air brake seat is mounted on the brake soleplate and is provided with air chamber mounting holes; the distance between the center of the cam shaft mounting hole and the center of the brake soleplate is 122-135mm; the miner axial distance between an air chamber mounting hole and the brake soleplate is 100-120mm; and the radial distance between the air chamber mounting holes and the center of the cam shaft is 110-130mm. The invention has the advantages that the distance between the center of the cam shaft mounting hole and the center of the brake soleplate is increased, and the novel air brake seat is designed so that the distance between the air brake seat and a steering knuckle external ball is larger, and the air chamber can obtain an enough mounting space to finally realize pneumatic brake.

Description

technical field [0001] The invention relates to an automobile, in particular to an automobile steering drive front axle braking mechanism. Background technique [0002] Existing automobile steering drive front axle braking mechanism mainly contains two kinds, and a kind of is pneumatic braking, and a kind of is hydraulic braking. Pneumatic braking is a main way of automobile braking at present, and its braking effect is better than that of hydraulic braking. The radial size of the outer ball of the steering knuckle of the steering drive front axle of the car is not less than 180mm. If the pneumatic brake is used, the center distance between the camshaft and the wheel axle is generally 120mm, and the outer diameter of the position where the camshaft is installed on the air brake seat is about 70mm. Interference will occur and installation will not be possible. Therefore, people just can only use the relatively poor hydraulic brake of braking effect. Contents of the invent...
