Description

Technical Field

[0001] The utility model belongs to the technical field related to steering knuckles, in particular to a disc brake front axle steering knuckle. Background Art

[0002] The front axle steering knuckle of a disc brake is an important part of the front axle of the vehicle. It connects the wheels and the steering system to ensure that the vehicle can turn accurately. The steering knuckle can withstand the driving force and steering force from the wheels, while allowing the wheels to turn relative to the front axle. In the configuration of the disc brake, the steering knuckle can provide a stable support surface so that the brake can work effectively, but it still has the following disadvantages in actual use:

[0003] When the disc brake front axle steering knuckle is working, the steering knuckle arm and the steering knuckle are directly installed together through the mounting earrings on it. After installation, the mounting earrings are subjected to impacts and other effects, which will cause damage and other faults. After damage, it can only be replaced as a whole. During the replacement process, the operation is not convenient enough;

[0004] The disc brake front axle steering knuckle is directly installed between the shaft neck and the steering shaft. During the installation process, the corresponding structure is directly installed, but in the working process, additional pins are required for cooperation, which is not convenient enough.
