Abstract
A brake actuator assembly may comprise a housing, a piston disposed in the housing and slidably engaged therewith, a resilient member disposed within the housing and coupled to the piston, and a deformable member disposed within the housing a coupled to the piston, wherein each of the deformable member and the resilient member are disposed radially between a piston rod of the piston and the housing.
Claims20
A brake actuator assembly, comprising:
- a housing;
- a piston disposed in the housing and slidably engaged therewith;
- a resilient member disposed within the housing and coupled to the piston;
- and
- a deformable member disposed within the housing and coupled to the piston, wherein each of the deformable member and the resilient member are disposed radially between a piston rod of the piston and the housing.

A wheel and brake assembly for mounting on an axle, comprising:
- a friction stack;
- a wheel comprising a hub coupled to the axle;
- a torque bar configured to engage with the wheel and rotate a brake rotor of the friction stack;
- and
- an actuator assembly configured to apply a brake pressure to the friction stack, comprising:
- a housing;
- a piston disposed in the housing and slidably engaged therewith;
- a resilient member disposed within the housing and coupled to the piston;
- and
- a deformable member disposed within the housing a coupled to the piston, wherein each of the deformable member and the resilient member are disposed radially between a piston rod of the piston and the housing.
7 more elements
A method of dynamically adjusting an actuator piston clearance, the method comprising:
- disposing a piston within a housing;
- coupling a deformable member to the piston radially between a piston rod and the housing;
- coupling a resilient member to the deformable member;
- and
- permanently deforming the deformable member in response to applying a brake pressure to the piston.
