摘要： A hydrostatic actuator and an arrangement for attaching it to a receiving component are provided. The hydrostatic actuator has a master cylinder containing a housing and a piston movable axially within the housing which acts on a pressure chamber filled with a pressurizing agent. The piston is driven by a rotary-driven electric motor having a stator and a rotor, by a rolling planetary transmission that converts the rotary drive to an axial motion. In order to be able to produce such a hydrostatic actuator with little need for construction space, cost-effectively and with better quality, a supporting of the rolling planetary transmission is simplified, and the cooling and shielding of an electronic controller and the pressure behavior of the hydrostatic actuator is improved.

摘要： A positive displacement hydraulic pump/motor assembly (1) includes a rotary cylinder block (3) having a central axis (5) and a generally circular array of cylinders (6) disposed in parallel relationship around the axis. A corresponding plurality of axial pistons (10) is reciprocably disposed within the respective cylinders. A drive shaft (12) effects rotation of the cylinder block about the central axis and a drive plate (15) is disposed at one end of the cylinder block (3) to effect sequentially staggered reciprocation of the pistons (10) in response to rotation of the cylinder block. A stationary valve plate (20) is disposed at an opposite end of the cylinder block. The valve plate (20) includes a valve face (21) adapted for sliding rotational engagement with a complementary mating face (22) formed on the cylinder block. The valve plate further includes at least one inlet port (24) adapted for fluid communication with a source of hydraulic fluid and at least one outlet port (26) adapted for fluid communication with an hydraulic load. The ports (24, 26) are disposed such that in use, hydraulic fluid is progressively drawn into the cylinders in sequence as the respective pistons are displaced away from the valve plate and subsequently expelled from the cylinders as the pistons are progressively displaced toward the valve plate. The pump/motor assembly further includes lift-off means in the form of an hydraulic lift-off piston (40) and cylinder (41), selectively operable to displace the cylinder block marginally away from the valve plate, thereby to minimise rotational resistance between the respective mating valve faces (21, 22) under predetermined operational conditions. The pump/motor assembly is adapted for incorporation into an energy management system operable in a driving mode, a braking mode and a neutral motor to provide supplementary drive from regenerative braking in a vehicle.

摘要： A hydromechanical drive assembly having a hydrostatic axial piston motor with a housing and a swash plate and a cylindrical drum located in the housing. A transmission having a housing is located downstream of and coaxial with the axial piston motor and a planetary gear is located in the transmission. A transmission-side driven shaft extends out of each end of the drive assembly. The cylindrical drum and the driven shaft have the same axis of rotation. Spring-actuated hydraulically releasable devices are located in the housing to non-rotatably connect the cylindrical drum of the axial piston motor directly to a ring gear which is non-rotatably connected to the driven shaft.
