POWER STEERING SYSTEM DETAILS


  1. CONSTRUCTION


    1. Vane Pump Assembly


      1. A compact and lightweight vane pump, which uses die-cast aluminum as the material for its housing, is used.

      2. A belt drive type vane pump is used.

      3. Models with 2TR-FE engine use a type of vane pump with a built-in reservoir tank.

    2. Power Steering Link Assembly


      1. A low friction rack shaft is used in order to achieve a steering operation feeling at the center position.

      2. Steering rack bushes are used to mount the steering gear on the vehicle. Accordingly, the rigidity in the left and right directions has been optimized and the vertical rigidity and the rigidity in the forward and rearward directions have been enhanced to optimize compliance steering and eliminate vibration from the ground.

      3. A check valve is provided at the high pressure port in order to reduce the extent of shocks applied from the road surface.
