Steering and Suspension Parts


Steering and Suspension Parts

Rod End

The rod end connect the center link to the steering knuckle on cars with conventional suspension systems and recirculating ball steering gears. On cars with MacPherson strut suspension and rack-and pinion steering gears, the rod ends connect the end of the rack to the steering knuckle. A rod end consists of an inner and an outer end. The rod end transmits force from the steering center link or the rack gear to the steering knuckle, causing the wheels to turn. The outer rod end connects with an adjusting sleeve, which allows the length of the rod end to be adjustable. This adjustment is used to set a vehicle’s toe a critical alignment angle.

Ball joint

Ball joints are the moveable link that connects the whole suspension system together, allowing for turning and road situation. Ball joint is used for he connection between pitman arm and upper or lower control arm. So Ball joints cause to direct wheel rotating through vertical axis. If the boot was teared Ball joint should be replaced with the new one.

Drag Link-Rod Arm

Drag Links consist of a long bar that provides a means of connecting the tie rods together, forming one big moveable linkage system. The reason it's called a Drag Link is because it "drags" the whole steering linkage from right to left on commercial vehicle.

Axial Joint

Axial Rod is used for the linkage of rack and pinion steering gears and wheel spindle assemblies. Axial rod passes the rotating movement of the steering wheel to the tie rod ends and causes the steering knuckles to turn the wheels.

Track Control Arm

Track control arm provide a connection between Pitman arm (wheel spindle) and chassis to maintain caster and camber angle of wheel. Pitman arm (wheel spindle) is supported by tarck control arm which can be divided into two main part; upper control arm and lower control arm. Ball joint has to be used to tie track control arm to the wheel spindle.

Torque Rod

Torque Rod is a connection rod used for tying of axle to chassis frame. Uncontrolled movement on an axle of vehicle going forward through road is transmitted to chassis frame on the dependence of rough road. A small portion of these uncontrolled movements (vibrations) is conveyed to the chassis by the torque rod as the rest great portion is damped by suspension system and tires. Beside the traction power of engine is transmitted to the wheel by the transmission system of vehicle. The inertia of vehicles weight and negative impression of the traction of wheels is conveyed on chassis frame of vehicle. Torque rod is connected firmly by bolt and nut between axle and chassis frame to maintain axle restraining from a bump or bounce on a road. This vital part damps the vibration by converting limited oscillation and small amplitude.

V-Torque Rod

V-Torque Rod has the same features of Torque Rod. Uncontrolled movement on an axle of vehicle going forward through road is transmitted to chassis frame on the dependence of rough road. A small portion of these uncontrolled movements (vibrations) is conveyed to the chassis by the v-torque rod as the rest great portion is damped by suspension system and tires. Beside the traction power of engine is transmitted to the wheel by the transmission system of vehicle.The difference between torque rod and v-torque rod is that ; v-torque rod offers future technology and is connected to one center ball pin.

Stabiliser Link

Stabiliser link provide comfortable ride for the passengers. Stabilizer bars are used to control body roll. The one end of the stabilizer link is tied to center link and the other end is tied to control arm or body of the vehicle or helezon coil according to design.

Idler Arm

The idler arm is used on vehicles with conventional suspension systems and parallelogram steering. This type of suspension and steering arrangement is used on virtually all rear-wheel-drive vehicles and many light trucks. Essentially, the idler arm is a pivoting support for the steering linkage. The idler arm consists of a bracket, an arm that connects the bracket to the center link of the steering linkage, and an internal pivot bearing. A few vehicles use two idler arms. The idler arm assists the pitman arm by supporting the steering linkage as it moves in the direction controlled by the steering gear.

Pitman Arm

A pitmann arm is used on vehicles with conventional suspension systems and parallelogram steering. This type of suspension and steering arrangement is used on virtually all rear-wheel-drive vehicles and many light trucks. The pitman arm consists of a splined arm that connects with the steering gear and a threaded bearing stud and seat. The lower part of the threaded bearing stud is covered with a protective dust boot that prevents dirt entry into the bearing and seat. The upper part of the bearing stud connects to the center link of the steering linkage. The steering gear shaft turns in direct relation to input from the driver. The pitmann arm attaches to the steering gear shaft and acts as a lever, converting torque from the steering gear to mechanical force for movement of the steering linkage.
