Abstract

See full text

A braking mechanism is provided for a hydraulic motor driven wheel utilizing a two-piece design of a hub that rotates by means of a drive shaft. A hydraulic chamber is created on the hub in which a piston resides. The piston is grounded (i.e., non-rotatable relative to the motor housing) in the sealed chamber. The piston face inside of the chamber has a radial set of face teeth. These face teeth are similar to the face teeth inside of the hydraulic chamber. When the chamber is pressurized, the piston face teeth are pushed away from the hub face teeth allowing the hub to freely rotate. When pressure is released from the chamber, a spring, or a number of springs, push the piston into the hub causing it to stop rotating relative to the piston.
