Abstract: A wheel hub for vehicles has a built-in brake assembly for stopping and parking the vehicle. A parking piston and a spring assembly of the parking brake are arranged within the ring gear support member, and impact on the brake piston of the multi-plate friction type wet brake, and the ring gear support member. The parking brake has a device for manually de-activating the parking brake from outside the hub. The device includes a screw that overrides spring pressure to move the parking piston away from the brake piston to manually release the parking brake.

Abstract: A differentially steered work vehicle is provided with a driving axle having a axle housing with an access opening. An access plate is secured to the access opening and is provided with steering components. The access plate is provided with a steering motor mount that passes through the access plate. A steering motor is mounted to the steering motor mount on the exterior side of the access plate. The interior side of the access plate is provided with a rotatable steering shaft having a first toothed end and a second toothed end. The first toothed end drives a first spur gear which is operatively coupled to the ring gear of a first planetary set. The second toothed end of the steering shaft is operatively coupled to a reverser gear that is also rotatably mounted to the interior side of the access plate. The reverser gear is mounted on a pin mounted to the interior side of the access plate.

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.
