TOYOTA COROLLA steering gear introduction

TOYOTA COROLLA steering gear is a key component in the vehicle steering system. Its main function is to assist the driver to control the direction of the vehicle more easily and improve driving comfort and safety. This model 45510-02490 is suitable for Toyota Corolla 1.8L left-hand drive manual transmission models. It adopts hydraulic power steering (HPS) to reduce the force required by the driver to turn the steering wheel through the pressure of hydraulic oil.

Working principle of TOYOTA COROLLA steering gear

The core components of the power steering include the rotary valve, the rack and pinion mechanism and the hydraulic system. Its main working process is as follows:

When the vehicle is driving straight

    ● The steering wheel is stationary, and the oil pump supplies hydraulic oil through the oil inlet.

    ● The hydraulic oil flows into the two working chambers of the steering gear through the gap to maintain the oil pressure balance.

    ● Since the rotary valve is not moving at this time, the rack piston is not under force, and the hydraulic oil directly returns to the tank, and the vehicle maintains a straight driving state.

When the vehicle is turning

    ● When the steering wheel is turned, the valve core of the rotary valve moves, allowing the hydraulic oil to enter the corresponding working chamber.

    ● There is a difference in the oil pressure of the two working chambers, and the pressure acts on the rack piston, causing it to move in the direction of the rack.

    ● The rack drives the front wheels to rotate through the pinion gear to achieve vehicle steering.

Return process

    ● When the driver stops applying steering force, the force on the steering wheel disappears.

    ● Due to the return torque of the internal torsion bar and the front wheel, the oil pressure difference between the two working chambers disappears.

    ● The steering wheel returns to its original position and the vehicle returns to the straight-ahead state.
