Embodiment Construction

[0023] exist figure 1 In the illustrated embodiment, a disc brake 1 for a commercial vehicle comprises a brake disc 2 and a brake caliper 3 straddling the brake disc 2 . The caliper 3 is usually attached via a torque plate or brake mount (not shown) to a caliper mounting bracket 4 which in turn is secured to the vehicle axle. The caliper 3 is actuated by an actuator 5, in this embodiment a spring brake actuator, controlled by the vehicle's pneumatic pressure. The actuator 5 acts on a brake pad application mechanism contained within the caliper 3 to press the brake pad 6 against the brake disc 2 to decelerate the vehicle. The invention is not limited to pneumatic actuators (e.g. electrically driven actuators could be used) or to particular types of brake caliper / mechanism arrangements (e.g. fixed bracket and sliding caliper with single sided brake pad application mechanism, or with fixing brackets and fixing calipers for the brake pad application mechanism on both sides). In...

Abstract

A system and method are provided for installing, removing and retaining brake pads in disc brakes, such as pneumatic disc brakes for commercial vehicles, in a manner that provides reliable retention of the brake pads while eliminating the need for a separate brake pad retainer. A preferred embodiment comprises a brake caliper mechanism having a brake pad abutment surface with radially positioned transverse grooves allowing brakes with corresponding protrusions on their transverse sides. The rotor is inserted through the opening of the brake caliper into the radially located groove until the back plate protrusion is aligned with the transverse groove, and the brake actuator behind the brake pad is advanced to place the brake pad in the operating position, in In this operative position, the actuator prevents the pads from realigning with the radially located grooves until the actuator is retracted to allow extraction of the pads.

Description

technical field [0001] The present invention relates to a disc brake for a vehicle, and in particular to a system and method for installing, removing and retaining brake pads in a disc brake, such as a pneumatic disc brake for a commercial vehicle type brake. Background technique [0002] Pneumatic disc brakes have undergone development and application on commercial vehicles since at least the 1970s and have begun to replace drum brakes due to advantages in areas such as cooling, fade resistance, and reliability in use. German patent application DE 40 32 886 Al, and in particular the document's figure 1 , discloses an example of such an air disc brake. In this design, a pneumatic diaphragm chamber (pneumatic actuator) is attached to the rear surface of the disc brake caliper housing, and the brake actuation force is applied to the brake actuator rod inside the caliper through a linear actuator rod. The brake's actuator rod in turn multiplies and transmits the force exerte...
