Abstract:
Hydraulic and pneumatic drive systems and fluid motors (12) and fluid pumps (10) therefor are disclosed. In such systems, rotation motion is converted to reciprocating motion or vice versa. In particular, a motion conversion means comprises a portion extending continuously and circumferentially around a central axis and extending in part longitudinally relative to the central axis, and a linking means, wherein the portion and the linking means are relatively rotatable about the central axis and a one of the linking means and the portion is fixedly coupled to a piston means, wherein the linking means and the portion are configured to cooperate whereby the reciprocating movement of the piston means causes relative rotary motion of the other of the portion and the linking means about said central axis. The other of the portion and the linking means may be coupled to a sleeve means to cause rotation thereof.

Abstract:
A hydrostatically driven vehicle has an engine operating a variable displacement propel pump, a displacement of which can vary based on an angle of a rotating swashplate, such that a fluid flow impelled by the pump transfers power to at least one propel motor rotating a wheel of the vehicle. An electronic controller of the vehicle senses an operating parameter of the system, for example, the angle of the rotating swashplate or the direction and speed of rotation of the propel motor with a sensor to yield an actual signal, and relays the actual signal to an electronic controller. The controller determines a desired angle for the rotating swashplate based on the control signal, and compares it to the actual signal from the sensor. Motion of the vehicle is stalled when the angle signal differs from the desired angle by a predetermined extent and for a predetermined period.
Abstract:
A hydrostatically driven vehicle includes an engine operating at a first speed and operably connected to a variable displacement pump in fluid communication with a hydraulic circuit. The pump includes a rotating swashplate being adapted to operate at selective angles, which dictate pump displacement ranging from zero to a maximum displacement. The pump is capable of providing a pump flow rate at the first speed when the pump swashplate is set to the maximum displacement, wherein the pump flow rate is greater than the maximum flow rate that may be received by the hydraulic circuit.
Abstract:
The present invention concerns a method for continuously changing speed ratios with a pressure coupling type of hydraulic device. The invention is based on the principle and the structure of a hydraulic or pneumatic pump, in which the rotor and the stator of the pump are used as the driving and driven elements of the device respectively. With ratios range from 0 to 1, stepless variable drive is realised by controlling the fluid flow discharged owing to the differential speed between the rotor and the stator. It can be also realised with a variable displacement type of hydraulic motor which is used to control the fluid flow and to feed back its output torque to the pump. The present device runs more efficiently than that in the art.
