Unit component

Electronically controlled variable-gear-ratio steering

Outline

  • The steering gear ratio can be varied according to the vehicle speed, so that a smaller steering angle produces a larger tire steering angle during low-speed travel or parking motions while the steering motion produces a smaller steering angle of the tire during high-speed travel, thereby increasing stability.
  • The function of this product is also used in the automobile collision avoidance support system, steering control at vehicle skid, and lane maintenance support system.

Variable flow control pump (V.F.C pump)

Outline

  • A small solenoid valve installed on the hydraulic pump controls the delivery flow according to the information about the vehicle speed and steering angle.
  • The steering feel improves and the energy saving property improves because the delivery flow is limited when the wheel is not steered.

Steering column

Outline

  • Supports energy absorption at tilting and telescopic motions as well as at collision.

Intermediate shafts

Outline

  • A linkage shaft between the steering wheel and steering gear needs large torsional rigidity.
  • The gap at the joint and slide is reduced, reserving calmness even during travel on rough terrains.

Power steering pump/Hydraulic hose/Reservoir tank

Outline

  • A pump generating a hydraulic power needed for the hydraulic steering system, transmission hose, reservoir tank and other components are provided in an optimized system.
