Abstract: A differential lock-up assembly for vehicles with a differential gear set has a main drive housing,a driving pinion gear being rotatable in the main drive housing,a ring gear engaging the pinion gear, a planet carrier secured to the ring gear and rotatably supported in the main drive housing,a set of pinion gears journalled in the planet carrier and a set of bevel gears engaging the pinion gears and journalled in the planet carrier and engaged to output shafts of the differential gear set,and a lockout clutch assembly with a pack of interleaved discs locking the planet carrier to one of the output shafts on the impact of pressurized fluid with the intermediation of a piston and cylinder assembly.

Abstract: A driven axle assembly for vehicles has an axle housing with a main drive, wheel hub units fixed to both sides of the axle housing and being driven by a drive shaft with different rotational movements on both sides of the main drive, within each wheel hub unit, a planetary gearing and a multi-plate friction type wet brake both being coupled to the drive shaft as well as to a drive unit of the vehicle, wherein the multi-plate friction type wet brake is arranged within a ring gear support member, and around planetary gears of the planetary gearing a ring gear is connected to them.The improvement achieved by this invention is that a driving assembly is coupled to the ring gear of the planetary gearing of each and every wheel hub unit arranged on the driven axle whereas a difference between the rotational speeds of the ring gear within the wheel hub units, respectively, are proportional to a difference between the rotational speeds of the wheel hub units arranged on the driven axle of the vehicle.

Abstract: An eccentric pump with lock valve and with bidirectional rotational operation, mainly for lubricant circulation of drives comprises a stationary outer casing having two parallel side walls and a cylindrical inner surface between the side walls, and further having inlet and outlet openings being sealingly separated and terminating in the cylindrical inner surface, a middle shaft arranged within the casing concentrically to the cylindrical inner surface and having a cylindrical surface being eccentric to the middle shaft as well as to the cylindrical inner surface of the casing, a circular sealing ring being sealingly displaceable in respect of the eccentric surface of the shaft as well as to inner wall portions of the casing, and further having a radial slot sealingly engaging a stationary pin with its both limiting surfaces.

Abstract: A driven axle assembly for vehicles has a lubricant circulation system, and the axle assembly comprises an axle housing with a main drive and a lubricant liquid in its inside, hollow axle casings fixed to both sides of the axle housing, a hollow wheel hub rotatably connected to each axle housing, the wheel hub having a flange for carrying a vehicle wheel rim as well as, in its inside, a planetary gearing and a multi-plate friction type wet brake, the main drive and the planetary gearing as well as the multi-plate wet brake being interconnected with a drive shaft on both sides of the main drive, respectively, and mechanism for making a lubricant flow within the axle assembly.
