Abstract:
A hydraulic device includes a gerotor assembly, a wobble stick, an output shaft, a housing assembly, a first port in the housing assembly, a second port in the housing assembly, first brake disks, second brake disks, a piston, and a biasing member. The gerotor assembly includes a rotor and a stator. The wobble stick connects at a first end to the rotor. The output shaft connects to a second end of the wobble stick. The housing assembly receives the gerotor assembly, the wobble stick and the output shaft. The first port is in communication with the gerotor assembly. The second port is also in communication with the gerotor assembly. The first brake disks connect to the output shaft. The second brake disks connect to the housing assembly. The piston is disposed in the housing assembly adjacent at least one of the brake disks. The piston cooperates with the housing assembly to define a brake pressure chamber. The housing assembly and the first and second ports are configured such that pressurization of either port results in pressurization of the brake pressure chamber. The biasing member is disposed in the housing and contacts the piston. The biasing member urges the piston toward at least one of the brake disks.
