GENERAL





  • The support method of the steering gear to the crossmember is realised by the left and right internal bushings with inner cylinders. This support method achieves higher rigidity and bilateral symmetrical design of the steering gear and improves the steering feeling.
  • Configuring the optimum flow characteristics and gear valve feature improves the handling stability.
  • Appropriate application of friction to the steering gear cuts off the disturbance from the road surface and improves the stability during the straight-ahead driving.
  • One-way check valve for the power steering fluid has been added in the steering gear. By reducing the kickback due to the disturbance from the uneven road surface, the handling stability has been improved.
  • Optimisation of the flexible tube in the high pressure hose reduces the pump noise.
