Universal joint for Lorain LRT 400

The universal joint, part number 211514, acts as a mechanical link within the drivetrain of heavy machinery. Its primary function is to transmit torque and rotary motion between two shafts that are not coaxially aligned, allowing for variable operating angles. This component is integrated into the drive shaft assembly, connecting the transmission to the differentials or wheel axles to ensure consistent power delivery to the drivetrain.

This component is compatible with Lorain LRT 400 and Lorain LRT Serie 445 rough-terrain cranes. It serves as a critical junction point where the powertrain must accommodate independent movement of components due to chassis design or suspension travel. By maintaining this connection, the joint ensures the mobility and traction of the crane during operation.

Universal joints typically consist of two yokes joined by a cross-shaped central element equipped with needle bearings. In a drivetrain system, these joints allow for the necessary angular flexibility between the transmission output and the driven axles. Proper function of this assembly is necessary to prevent excessive vibration or mechanical noise during rotation, ensuring that power is transferred efficiently from the engine through the transmission to the final drive units.
