Abstract

The invention discloses a knuckle assembly for a pneumatic brake wheel. The knuckle assembly comprises a knuckle mechanism, a wheel axle tube mechanism and an air chamber support mechanism, wherein the end part of the wheel axle tube mechanism is sleeved with the knuckle mechanism, and the knuckle mechanism is detachably connected with the end part of the wheel axle tube mechanism; the air chamber support mechanism is mounted at the side part of the knuckle mechanism and detachably connected with the side part of the knuckle mechanism; and a camshaft yielding hole is formed in the position close to the joint part of the knuckle mechanism and the air chamber support mechanism. According to the knuckle assembly for the pneumatic brake wheel, the problem that the joint part is invalid due to the additional bending moment produced by a push rod of a brake chamber when an air chamber support mechanism is mounted on a brake bottom plate in the prior art is solved; and at the same time, the air chamber support mechanism is mounted at the side part of the knuckle mechanism, so that the mounting height of the outside brake chamber is effectively reduced, and the operation space is saved.

Description

technical field [0001] The invention belongs to the technical field of automobile brakes, in particular to a steering knuckle assembly for air brake wheels. Background technique [0002] The steering knuckle assembly in the air brake steering axle mainly plays the role of bearing and steering, wherein the wheel axle tube body and the steering knuckle arm are installed on the steering knuckle body. In the prior art, the wheel shaft tube body is generally connected to the steering knuckle body by welding. During the use of the axle, the root of the wheel shaft tube body (also where the weld is located) is under the greatest force. Once a quality problem occurs in the weld, it may Cause the wheel axle tube body to break. The air chamber support mechanism is generally installed on the brake floor, and when the air chamber support mechanism is installed on the brake floor, the air chamber support mechanism is a cantilever beam structure, and the air chamber push rod will have a ...
