ABSTRACT:
A spur gear transmission for a drive unit of an industrial truck having an integrated wet running disk brake. A first disk carrier is arranged on one of the spur gears. First braking disks are mounted on the disk carrier. A second disk carrier is fastened in the transmission housing, second braking disks being mounted on the second disk carrier, such that the first and the second braking disks are arranged alternately and cooperate. The spur gear having the first disk carrier is axially movable against the force of a spring by a pressure pin extending through the transmission housing and operable from outside, with the braking disks being pressed against one another between the spur gear and a bearing surface in the transmission housing. A two-arm lever is provided, one lever arm of which can be operated by the driver and the other lever arm of which lever rests on the pressure pin. A hydraulic cylinder with a movable piston therein is housed in the lever arm and is connected through a pipeline, for example, to a brake pedal, to be operated by the driver. The cylinder yields when the piston is loaded with pressure and operates thereby the pressure pin. Besides this hydraulic brake operation intended for the travelling operation there is also provided a mechanical operation through a cable line, which is, for example, connected to a brake lever, as a locking brake.
