Caster is the forward or backward tilt of the steering axis. Caster is measured in degrees from the steering axis to vertical as viewed from the side. Backward tilt from the vertical line is called “positive Read more Caster and Caster Trail
Steering Axis Inclination
The axis around which the wheel rotates as it turns to the right or left is called the “steering axis”. This axis is found by drawing an imaginary line between the top of the shock absorber’s upper Read more Steering Axis Inclination
Toe (Toe Angle, Toe-in and Toe-out)
Toe is the inclination of the wheel front and rear as seen from above the vehicle. The wheel installation angle is called the toe angle. When the front of the wheels are closer than the rear of the wheels, Read more Toe (Toe Angle, Toe-in and Toe-out)
Wheel Alignment Service
Frequent inspection and correction of wheel alignment are ordinarily not necessary under normal conditions of use. However, if the tires are worn unevenly, if steering is unstable, or if the suspension Read more Wheel Alignment Service
What is an Impact-absorbing Mechanism?
When a vehicle involved in a collision, this mechanism helps prevent the steering main shaft from injuring the driver in two ways: by the breaking at the time of the collision (primary shock); and by reducing Read more What is an Impact-absorbing Mechanism?
What is an Automotive Gear Housing
1. Description
The piston in the power cylinder is positioned on the rack, and the rack moves due to fluid pressurized by the vane pump acting on the piston in either direction. Fluid pressure leakage Read more What is an Automotive Gear Housing
The idea of New PPS (Progressive Power Steering)
1. Description
The new PPS(Progressive Power Steering) varies, the steering operation effort in accordance with the vehicle speed. The steering effort is lighter at low speed and heavier at high speed.
2. Read more The idea of New PPS (Progressive Power Steering)
What is EPS (Electric Power Steering) ?
1. Description
EPS (Electric Power Steering) generates the assist torque by the motor for steering operation and reduces the steering effort. Hydraulic power steering uses the power of the engine to Read more What is EPS (Electric Power Steering) ?
Outline of an Automotive Brakes
In order to decrease the speed of a running vehicle and bring it to a stop, it is necessary to generate force to slow the rotation of the tires. When the driver operates the brake pedal, the brake device Read more Outline of an Automotive Brakes
