Utility Vehicle Disc Brake Pad Resetting to Prevent Rubbing Torque

The resetting device is segmented into two separate V-shaped spreading elements, each independently mounted on the brake carrier and acting on opposite brake linings. This segmentation allows for simpler individual component design and manufacturing compared to a single complex resetting mechanism, while collectively achieving the function of preventing residual rubbing torques on both sides of the brake disk.

Instead of using a complex multi-component resetting device as proposed in prior art, the invention inverts the approach by using simple V-shaped spring elements that passively reset the brake linings through elastic deformation. The spring legs of the V-shaped elements are held at their ends on the brake linings, and their natural elasticity provides the resetting force without requiring complex actuation mechanisms.

The V-shaped spreading elements provide periodic action by alternately compressing and expanding. During braking, the spring legs are compressed as brake linings are pressed against the brake disk. After brake release, the springs expand to actively push the brake linings away from the brake disk, creating a periodic reset action that prevents continuous rubbing and reduces energy loss.

The resetting function is achieved through self-service by utilizing the elastic properties of the V-shaped spring elements themselves. The springs automatically compress during braking and expand during release without requiring external actuation or complex resetting mechanisms, thereby preventing residual rubbing and reducing fuel consumption through a self-regulating elastic recovery process.
