Joint crosses for trucks and buses
The DT Spare Parts brand offers a complete range with more than 30 000 different spare parts for trucks, trailers and buses, including all standard joint crosses. In addition, the DT brand carries all appropriate component parts for the respective drive shaft, including flanges and central bearings.
The propeller-shaft is used to transmit the drive torque from the gearbox to the axle drive. The length of the drive shaft depends on the wheelbase of the vehicle. It consists of a metal shaft which transfers the drive torque and engine speed and compensates for length variations through spring movements of the vehicle.
With the help of the joint cross, the drive shaft can rotate in any angle position which is determined by the movement between the transmission and the rear axle. A diffraction angle of up to 25° is possible. The joint cross consists of a steel cross which runs in needle bearings between the drive shaft and the connecting flange bracket.
A distinction is made between maintenance-free and non-maintenance-free joint crosses. Non-maintenance-free joint crosses have standardised grease nipples for lubrication when required.
