ABSTRACT:
A rotary hydraulic piston transmission located within an axle housing is provided that includes reduction gearing and a mechanical differential for the purpose of compactness and simplicity of manufacture. The axle housing comprises two main elements which, when attached together, form internal cavities, one cavity expressly used for the hydraulic transmission which comprises a hydraulic pump and a hydraulic motor mounted on either side of a partition member, and where the partition member divides the cavity into an upper and lower chamber for location of the hydraulic pump and hydraulic motor, respectively. The remaining cavities contain the reduction gearing and mechanical differential, and where the cavity containing the hydraulic transmission is purposely segregated from the remaining cavities in order to prevent material worn from the gears from entering the oil chambers of the hydraulic transmission.
