Steering housing
The steering gear transmits the rotational movement of the steering wheel via the tie rod to the front axle of the vehicle. The steering torque is transmitted via a rack and pinion in the steering housing. The trend towards steer-by-wire systems enables improved driving and steering characteristics. This technology also lays the foundation for self-driving cars by enabling more direct and precise steering. Overall, the steering gear plays a central role in the vehicle’s steering ability and safety.
