A wheel hub with integral planetary gear mechanism and multidisk brake, in which the outer plates of the brake are actively connected directly to the wheel hub and the inner plates are connected to the axle body via a brake carrier, is to be of simple design and easy to install and to be of small structure. According to the invention, the brake carrier (,), together with the brake piston (,) and its seals (,), the brake plates (,), a brake support ring (,) and the integral gear (,) being attached to this first installation assembly (M,) and the brake carrier (,) having an internally arranged attachment flange (,) which can be connected to the axle body (,) via attachment elements (,) for attaching the entire first installation assembly (M,), and that the cup-shaped wheel hub (,), together with the planet gears (,) and their bearings (,), is designed as a second installation assembly (M,), this second installation assembly (M,) being designed in such a manner that it can be pushed over the first installation assembly (M,).

Wheel hub with integral planetary gear mechanism and multidisk brake

A two-speed transmission with hydraulic actuation of the shifting operations under load for hydrostatically operated work machines, particularly caterpillar-track excavators, having a planetary gearing provided with double planet gears, and having packs of discs which are arranged coaxially around the axis of the sun gear of the planet gearing and which act as a clutch or as a brake, respectively. The planet carrier of the planetary gearing is formed as a flywheel and the shifting step of the transmission which serves for starting the work machine is shifted by means of compression springs, and the parking brake, biased by springs, connects the clutch and the brake non-rotatably relative to the housing of the transmission.
