Definition
The steering knuckle arm, also called the trapezoidal arm, is the last stage of the power transmission component of the steering transmission device. The steering knuckle arm is installed on the left and right steering knuckles, and the other end is connected by a ball pin and a tie rod.
The steering knuckle is the final steering component, but how to connect the fan-shaped motion generated by the steering arm to the left steering knuckle, so the steering knuckle arm is installed on the left steering knuckle, and it is connected by the steering longitudinal tie rod. Connect with the steering rocker arm and realize the steering function.
Effect
When a car is driving, it often needs to change its driving direction (steering). Usually, when the vehicle is turning, the driver applies a steering torque to the steering wheel. This torque is amplified by the steering shaft, transmission shaft, and steering gear. After that, the torque is transmitted to the steering rocker arm, and then transmitted to the steering knuckle and the steering knuckle arm on the steering knuckle through the steering straight rod, and finally transmitted to the wheel hub to deflect the wheels. It can be seen that the structure requirements of the steering knuckle arm have the function of connecting the straight rod and the wheel hub, and have the steering function.
