Embodiment Construction

[0021] 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 base bracket 4 which in turn is secured to the vehicle wheel 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 / mount arrangements (e.g. fixed bracket and sliding caliper with single sided pad application mechanism, or with fixing brackets and fixing calipers for the brake pad application mechanism on both sides). In this em...

Abstract

A disk brake having a brake caliper mount (4) having brake pad abutment surfaces having radially-oriented (11) and lateral (12) grooves which permit a brake pad (6) with corresponding projections (16) on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves (11) until the backing plate projections are aligned with the lateral groove (12), and advancing the brake actuator behind the brake pad (6) to place the brake pad (6) in an operating position in which the actuator prevents the brake pad (6) from realigning with the radially-oriented grooves (11) until the actuator is retracted to permit brake pad extraction.

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 for commercial vehicles 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 A1, 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 transmits and multiplies the force exerted by th...
