A ball ramp caliper brake is disclosed. The brake can include a housing having an actuator side with a first pad nearer thereto and a carrier side with a second pad nearer thereto; the actuator side including ball ramps on an inner part, and threaded holes, the carrier side including housing holes therethrough; bolts respectively passing through one of the housing holes and respectively threaded into one of the threaded holes, to thereby compress a respective spring against the first pad; a lever having ball ramps facing the actuator side ball ramps; and a plurality of balls each being between respective ones of the ball ramps; wherein the springs are positioned coplanar with a radial center of the ball ramps, such that force of the springs provides constant compressive load on the ball ramps, and such that the force does not cause the first pad to tip.

Brake housing

A spring applied, hydraulically released brake includes a housing having an open end adapted to align with a vehicle surface and an internal ring extending from an inner perimeter of the housing; a piston; a disc stack including a thicker stationary disc including a tab with a hole therethrough, the hole receiving a slotted spring pin, the slotted spring pin slidably receiving a pin spring over a portion thereof; and a spring assembly adapted to urge the piston into contact with the thicker stationary disc to establish a default position of the brake; where, in a released position of the brake, the piston is not in contact with the thicker stationary disc, and the pin spring urges the thicker stationary disc into contact with the internal ring of the housing to thereby prevent the thicker stationary disc from free floating.

A caliper brake () includes a housing () formed of a first housing portion () and a second housing portion (). Each of the first housing portion and second housing portion include a channel () extending therethrough. The channels () include pins () for receiving one or more shims () thereon. Brake () includes a first stator assembly () and a second stator assembly () that are separated by a first distance when no shims () are on the pins (). The first stator assembly () and the second stator assembly () are separated by a second distance less than the first distance when one or more shims () are on the pins ().

A brake () includes a piston () housing one or more springs () therein. The one or more springs () are adapted to urge an extension () of the piston () into contact with a disc stack () in a default position of the brake (). Piston body () may be latitudinally offset from disc stack () by a distance (). The brake () includes a manual release feature ().

A brake () includes a housing () formed from a first housing portion () capable of receiving a second housing portion (). The first housing portion () houses a piston () and a plurality of springs (), and the second housing portion () houses an alternating arrangement of discs () for enacting a braking function. The second housing portion () further includes torque pin holes () for receiving torque pins () therein. Each torque pin () is secured with a plug () to secure stationary discs (A,B,C) in place. The stationary discs (A,B,C) have extending ears () positioned between torque pin grooves (), which further receive the torque pins ().

Spring applied, hydraulically released wheel-mount brake having improved stationary disc support

A brake assembly adapted to be mounted to the flange of an axle housing. The brake assembly includes a stationary plate having a plurality of threaded holes therein. The brake assembly also includes a mounting sleeve positioned adjacent to the axle housing flange opposite the stationary plate. A plurality of holes are provided through the mounting sleeve and are aligned with the threaded holes in the stationary plate. A bolt is received through each of the holes in the mounting sleeve and the aligned holes in the axle housing flange and the threaded holes in the stationary plate to secure the brake to the axle housing. The mounting sleeve may be provided in two or more separate pieces in order to facilitate installation.

Brake

A parking brake system includes an engine oil pressure switch normally controlling the activation of a parking brake. The controller is actuated to temporally ignore a communication from the engine oil pressure switch so that the brake may be released even when the engine is disabled.

A caliper brake () is adapted to act upon a stator () to engage a rotor of a vehicle. A housing () carries both a spring applied hydraulically released piston assembly () and a pressure intensifying piston assembly (). The assemblies () are in fluid communication with each other. The assembly () includes a piston () and a spring assembly () which urges the piston () into a first position engaging the stator (). The piston assembly () includes a pressure intensifying (PI) piston () which is in a first position when the piston () is in the first position. When the PI piston () moves from a first position to a second position, the fluid acts upon the piston () thereby disengaging the piston () from the stator ().
