Problems solved by technology

In some configurations, due to the angle at which the bolt is inserted into the caliper and interference with the caliper body, the tool cannot wrap around the nut for proper installation
If the actuator is not flush with the caliper, it may result in reduced function or loss of function of the air disc brake assembly

Embodiment Construction

[0012] figure 1 A cross-section of the actuator assembly 12 as part of the prior art brake assembly 10 is shown mounted on an air disc brake caliper 16 . The actuator assembly 12 may be an Endurasure TM Spring Brake Housing, available from Bendix Spicer Foundation Brake LLC of Elyria, Ohio. Caliper 16 can be ADB22X TM Parts of an air disc brake, also available from Bendix Spicer Foundation Brake, LLC. The actuator assembly 12 includes at least one fixed fastener 14 . Fastener 14 may be welded or otherwise permanently secured to the housing of actuator assembly 12 . Fastener 14 is typically a threaded bolt secured parallel to the central axis of actuator assembly 12 .

[0013] The angle θ is established so that the pushrod (not shown) of the actuator assembly 12 acts on the lever 15 inside the air disc brake caliper 16 . Face 13 of caliper 16 is generally at an angle θ relative to the axis of brake assembly 10 to receive actuator assembly 12 . The angle Θ is typically be...

Abstract

A braking assembly (10) for an air disc brake comprises an actuator assembly (21) having a service portion (23), at least one mounting stud (22a, 22b) attached to the service portion, and an air disc brake caliper (27) having a bore (28) for receiving the at least one mounting stud (22a, 22b). The mounting stud is pivotable with respect to the service portion for installation on the air disc brake caliper.

Description

technical field [0001] The present invention relates to an embodiment of a device for mounting an actuator assembly to an air disc brake caliper for an air brake equipped vehicle. Background technique [0002] Air disc brakes convert air pressure into braking force. When the driver applies the vehicle brake pedal, air enters the service brake chamber of the actuator assembly through the supply port. The pressure expands the diaphragm, which moves the pressure plate and pushrod of the actuator assembly forward. When the actuator assembly is mounted to the air disc brake assembly, the pushrod acts on the inner lever of the air disc brake, causing the inner brake pads to move towards the rotor. Further movement of the bridge on the inside of the air disc brake forces the caliper away from the rotor, which in turn pulls the outer brake pads into the rotor. Proper alignment of the actuator assembly relative to the caliper body of the air disc brake is necessary to ensure prope...
