Abstract: Disclosed is a transmission having an input shaft coupled to a motor unit on one side of the transmission and a braking device located on the other side of the unit. Planetary gear trains are located together on one side of the gear box with shafts coupled to the drive wheels or tracks extending through the braking unit on one side and through the gear box on the other. The gear box is connected to the planetary gear train by an output shaft and housing which is also connected to the braking device. Finally, a steering device is located within the transmission housing and serves to controllably interconnect the planetary gear of the planetary gear trains. This advantageously permits the brake unit to be mounted outside of the transmission housing which includes the planetary gear trains, the gear box and the steering device.

Abstract: A driven wheel hub suitable for industrial vehicles, agricultural machine civil engineering equipment and materials handling equipment is closed by a removable cover independent of a flange enabling a wheel to be attached to it. It comprises a hollow body within which is a gear assembly and at least one brake disk constrained to rotate with the wheel shaft, the clamping of which is controlled by a hydraulic control unit. The hydraulic control unit is entirely accommodated within a housing formed for this purpose within the corresponding stub axle, and this housing is open in the axial direction on the same side as the cover.

Abstract: The invention provides a modification to a wheel hub of the kind comprising hollow body housing a wheel speed reducer having a pinion carrier which is locked for rotation with the hollow body. According to the invention, splined mounting means is provided between the pinion carrier and the hollow body for locking the pinion carrier in rotation with the hollow body. Mounting means of this kind require only a small radial space, and the radial bulk of the assembly can therefore be reduced with this arrangement. The invention is particularly applicable to the hubs of driving wheels for industrial vehicles, agricultural machines, public works machines and load-handling machines.

Abstract: A hub for a wheel having a built-in brake assembly and suitable for use in ndustrial vehicles, agricultural machinery, civil engineering plant and materials handling plant comprises a stub axle on which is rotatably mounted a hollow body forming a casing to contain a lubricating and cooling fluid. A brake assembly with fixed and rotatable disks is disposed within the hollow body inside an annulus constrained to rotate with the stub axle. Associated with the annulus is a scooping device adapted to provide communication between the interior of the annulus and the annular space between the annulus and the hollow body, for improved supply of the lubricating and cooling fluid to the interior of the annulus.

Abstract: The invention is applicable to a wheel hub of the kind comprising within a hollow body closed by a cover, a reducer having a pinion-carrier, and a brake with a brake disc capable of being subjected to an axial clamping force which is counter-supported by the cover. According to the invention, the pinion-carrier forms a part which is separate both from the hollow body and from the cover and which bears axially on an abutment itself locked axially on the hollow body, thereby itself closing the hollow body transversely immediately before the cover. The result is that in order to unclamp the brake manually, it is simply necessary to act on the cover. The invention is applicable, in particular, to industrial vehicles, agricultural machines, public works machines and load-handling machines.

Abstract: A wheel hub suitable for industrial vehicles, having, in a hollow body a uction gear and a brake being located at the end of the shaft of the reduction gear. The brake has, alternating with interpolated discs rotationally fast on the hollow body, a plurality of brake discs rotationally fast on the shaft of the reduction gear, the interpolated discs being mounted to rotate freely on a single support column which is parallel to the said shaft, is offset in relation to the latter and is fixed to the hollow body.
