| 20100178188 | GEROTOR MOTOR AND BRAKE ASSEMBLY - 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. | 07-15-2010 |
| 20090008988 | CONTROL COMPONENT FOR HYDRAULIC CIRCUIT INCLUDING SPRING APPLIED-HYDRAULICALLY RELEASED BRAKE - A control for use in a hydraulic circuit where the control can act as a valve and an auxiliary pressure source for the hydraulic circuit. | 01-08-2009 |
| 20080307784 | HYDRAULIC TRANSMISSION ASSEMBLY - The present disclosure relates to a hydraulic transmission assembly for a ground vehicle comprises a pump unit and a hydraulic motor assembly connected to the pump unit. The pump unit includes a driven shaft configured to operably connect to a motor of the ground vehicle. The hydraulic motor assembly includes a motor housing configured to rotatably mount to a wheel assembly of the ground vehicle. The housing has a central opening. A stationary output shaft has a first end section received in the central opening and a second end section configured to rigidly attach to a frame of the ground vehicle. The output shaft includes at least one internal fluid passage in fluid communication with at least one fluid passage of the pump unit. Pressurization of the hydraulic motor assembly via the pump unit rotates the motor housing relative to the stationary output shaft which, in turn, rotates the wheel assembly in one of a first direction and second direction. | 12-18-2008 |
