XCMG Road Roller Universal Joint Assembly 860146798

The universal joint, also known as a U-joint, in a road roller is a crucial component of the machine's drivetrain system. Here's a detailed overview:

Function:

The universal joint is designed to transmit torque and rotational motion between shafts that are not in a straight line with each other.
In a road roller, universal joints are typically used to connect the transmission or drive shaft to the axle shafts or wheels.
They allow for power transfer while accommodating the vertical movement of the axle or wheels due to road irregularities, ensuring smooth operation and minimizing stress on the drivetrain components.
Construction:

Road roller universal joints consist of a cross-shaped or spider-shaped component with needle bearings at each end.
The ends of the cross or spider are connected to yokes or flanges on the shafts being joined.
The bearings allow the cross or spider to pivot and accommodate angular misalignment between the shafts while transmitting torque.
Operation:

As the transmission or drive shaft rotates, torque is transmitted through the universal joint to the axle shafts or wheels, allowing the road roller to move forward or backward.
The universal joint allows for smooth power transmission even when the angles between the shafts change, such as during turns or when the roller encounters uneven terrain.
