Abstract: The invention relates to a gerotar type rotary piston machine. The casing has a main axis and the gerotor gear set includes an internally toothed ring member with the teeth thereof in the form of rollers and an externally toothed star member which is rotatable about its own axis and orbital about the casing main axis. A main drive shaft is rotatable about the casing axis and a universal type wobble shaft connects the main shaft to the gerotor star member. An insert member is disposed internally of the ring member which has recesses for receiving the rollers of the ring member. The star gear and the insert member have a combined thickness equal to the width of the ring gear. The star gear has a centrally disposed slot and the wobble shaft has a blade shaped portion disposed in the slot. The insert member has a central bore and the blade portion of the wobble shaft extends through the star gear into the central bore. The dimensions of the recesses of the insert member are selected that the axially parallel lines of contact between the rollers and the star gear lie within these recesses.

Abstract: The invention relates to a hydrostatic-steering system having two or more motors for the power steering of two or more wheels, or two or more pairs of wheels. The motors are arranged in parallel in a hydraulic circuit and a metering type control device operated by a steering wheel is used for controlling the distribution pressurized hydraulic fluid to the motors. A fluid stream quantity divider is utilized to supply equal quantities of pressurized fluid to the motors. Each of the motors has valve means associated therewith having two or three operative positions including a neutral or bypass position. The other operative positions facilitate the operation of a motor such that the turning of the steering wheel in one direction effects the operation of the motor in a selected one of two possible directions. With this arrangement, for example, it is possible to have the front wheels of a vehicle turn in one direction and the rear wheels of the vehicle turn in either selected direction as desired.
