Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a steering knuckle. Background Art

[0002] The steering knuckle, also called the horn, is one of the main parts of the steering axle of the car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the load of the front of the car, support and drive the front wheel to rotate around the kingpin to make the car turn. When the car is in motion, the steering knuckle, as an important part of the suspension system, bears the force and torque brought by the control arms, brake calipers, and wheel hub bearings, and bears high alternating loads during the driving of the car.

[0003] When installing a shock absorber on a traditional steering knuckle, the shock absorber needs to be installed in the shock absorber installation hole of the steering knuckle; the installation hole is pre-tightened using a pre-tightening device, and bolts and nuts are installed. Since the contact surface between the shock absorber installation hole of the steering knuckle and the shock absorber is designed in an arc shape, the step of installing the shock absorber into the shock absorber installation hole requires workers to have a certain level of proficiency or use special assembly equipment to ensure that the shock absorber is installed to the set position and size accurately. It is too dependent on manual judgment and has poor stability. The use of special assembly equipment for installation results in cumbersome assembly steps, difficulty in improving assembly efficiency, and increased production costs.

[0004] Therefore, it is necessary to optimize the structure of the existing steering knuckle so that the shock absorber and the steering knuckle can be accurately positioned during assembly while ensuring the strength and stiffness of the steering knuckle, thereby simplifying the assembly process steps and improving assembly efficiency.
