Long tie-rod transmits the actions transmitted by short tie-rod to the axle located on the other side. Long tie-road connected to selector lever and right/left rods transmits the action of selector level to the rods. It is used for transmission of steering actions to the front wheels and for optimum handling. Long tie-rod provides a precise direction and secure driving. A centrally located part allows for optimal adjustment of both wheels.
Short tie rod
Short tie-rod directs the steering action initiated in the steering gearbox, finally transmitting action of steering arm to the wheel. Short tie rot connects the joint to the gooseneck. It acts like a joint which transmits left or right action of selector lever backwards and forwards.
Tie rod end
Tie rod ends are the parts which transmit the movement occurring when you turn the steering to the wheels. Tie rod end is composed of a joint and a body. It transmits the action of steering tie-rod to the slant neck. The resulting push force enables wheel to turn vertically to the road axis. Length of tie-rod-end can be changed and adjusted during the assembly.
Tie-rod-ends located on the short tie-rods and short tie-rods transmits the force to fittings and enables movement on both axes. Tie-rod-ends are produced with state-of-art technology with the use of special housings or rubber parts. Subjected to continuous optimization, the structure of the tie-rod-end plays a significant role in safe driving, making it a safety part.
Ball joint is a part used for connecting the king pin to wishbones. Ball joint is used for connecting upper and lower wishbones arms to pitman rod. The part connecting king pin to upper wishbone is called as upper ball joint and the part connecting it to lower wishbone as lower ball joint. Ball joints are lubricated to make them ready-to-assembly during the production and cannot be lubricated later.
Axial joint is used for connection between the hydraulic cylinder and the tie rod end fixed to the wheel. It is the fitting which transmits the action of steering wheel to the tie rod end, enabling wheels to rotate horizontally. Axial joint must have a swinging angle which enables maximum rotational motion of the wheels.
Uncontrolled movements, which occurred on the wheels depending on the form of the road as a result of motion of the vehicle, are transmitted to axle body. In commercial vehicles, torque rod used for connecting the axes to the chassis dampens on the wheels a part of such uncontrolled movements and vibrations, while large parts of them are transmitted to axle.
Rod / Strut, Link Stabilizer
For driving comfort purposes, Rod / Strut, Stabiliser is a coupling element of suspension system that control the horizontal and vertical swaying motions of vehicle body. Depending on the design, one end of the stabilizing tie rod is connected to balance rod, the other end is to wishbones arms, vehicle body and coil spring. Thanks to this connection, control on the steering wheel in sharp turns increases, preventing vehicle from drift, skid and wobbling.
