A vehicle in a driverless transport system has a drive unit which includes an electric motor, a gearing and a drive wheel with a common axis of rotation, is supported on the underside of the vehicle for pivotal movement about a vertical axis of rotation by a ring bearing, and serves only the driving and steering, the vehicle traveling on separate support wheels. A substantially horizontal bracket projects from both sides of a housing of the motor or gearing parallel to a plane of rotation of the drive wheel, one end of the bracket being supported for pivotal movement about an axis directed parallel with respect to the common axis of rotation on an arm extending downwardly from a support plate supported by the ring bearing, the other end of the bracket being supported with respect to the ring bearing by a substantially vertically acting spring arrangement pivotally supported on the bracket and/or the support plate. The spring arrangement can include an arrangement for changing the spring tension.

A shaft support structure for a rotatable shaft having at least one gear thereon, the shaft and gear being oriented in a transmission housing. The shaft is twice supported: once directly on the transmission housing in one opening, and once in a bearing bracket which is provided in a second opening in the transmission housing. The axially spaced openings for the shaft in the transmission housing are out of alignment. However, the support structure in the transmission housing for the shaft provides an axially aligned support for the shaft. The bearing bracket effects a centering of the shaft support in the transmission housing.

A friction clutch for use in a gear changing transmission for facilitating a power transmission from a rotating shaft of a working exhaust-gas turbine onto a crankshaft of an internal combustion engine, which friction clutch, depending on the engine and/or turbine speed, automatically closes in the direction of engagement and opens in the direction of disengagement, with the friction members of the clutch being able to be compressed in the direction of engagement against a spring force (cup springs) by a piston of a rotating cylinder-piston-unit provided on the drive side of the clutch, such that a fluid conveyed from an external pump into the cylinder applies a fluid pressure onto the piston in response to rotation (centrifugal force). The engine lubricant is preferably used as the fluid.

Apparatus for disengaging a friction clutch which couples an exhaust gas

A pump 11 is provided in a gear-shift mechanism, in particular a boat reversing gear transmission, in order to supply the hydraulically operated friction clutches with pressurized oil. The pump 11 sucks oil through a fine-mesh filter 19 out of the sump 21. The fine-mesh filter 19 is arranged in a separate filter chamber 12 which is connected through a suction pipe 13, 15 to the sump 21 and to the suction side of the pump 11. The two suction pipes are arranged in such a manner with respect to one another that the filter chamber 12 is always filled with oil. A dry running of the pump 11 during starting is avoided in this manner. The fine-mesh filter 19, in the form of a removable filter cartridge 20, allows the flow of oil from the inside thereof to the outside and is arranged for easy access from above.

In a seal arrangement between a stationary and a rotating machine part, for example, between a transmission housing and a hollow sleeve exiting from the housing, there are arranged two V-rings oriented concentrically to one another in the one machine part, the lips of the seals cooperating with the other machine part. To extend the service life of the seal arrangement, a first V-ring is first in an effective position and a second V-ring is supported for movement from a noneffective position (A) into an effective position (B) at a later time by means of a device which can be operated from outside.

A drive unit for a rail vehicle has a motor-gearing unit which is supported on at least one wheel-set axle of a bogie and which includes either a motor which extends in the longitudinal direction of the vehicle and has miter gearing units connected to both ends of a motor which extends parallel to the wheel-set axle and has a spur gearing unit coupled with its drive shaft. Each miter gearing unit or the spur gearing has as its output a hollow shaft which concentrically surrounds the respective wheel-set axle. The hollow shaft is connected to the associated wheel-set axle by an elastic coupling which permits axle dislocations and shaft-angle deviations, and also by an elastic bearing which transmits the weight of the motor-gearing unit to the axle. The elastic bearing can be provided laterally of the gearing unit on the hollow shaft, or can be provided within the hollow shaft. For countering tilting moment and mass-acceleration forces, at least one lever is provided as a support member and is elastically hinged to the motor and to the vehicle frame or the bogie.

A joint coupling, in particular for transmitting the motor output in electrically driven rail vehicles to a drive axle, includes a hollow shaft which is provided on a frame or bogie, and the drive axle is enclosed by the hollow shaft and is arranged radially movably with respect thereto. Each of two linkage elements are hingedly connected both to a first flange member which is rigidly connected to the hollow shaft and also to a second flange member which is connected rigidly to the drive axle. The linkage elements are each with their free ends hingedly connected to an intermediate member which surrounds the drive axle and is radially movable with respect thereto. The intermediate member is divided into two halves in a direction transversely to its axis and the axis of the drive axle, which halves are connected releasably to one another.

Differential coupling

A drive train for a steerable drive wheel of a vehicle includes a spur gear stage and a bevel gear stage in a drive train housing which is supported for pivotal movement about a vertical axis. The drive wheel is driven through a horizontal axis from a vertically arranged motor. The housing is divided so that the axle-base change of the spur gear stage which is necessary when changing the drive wheel width requires different parts only for the part of the drive train housing which surrounds the spur gears. The remaining part of the drive train housing, which contains the bevel gear stage, is always the same. A slewing ring can be integral with the housing part which surrounds the spur gears. Furthermore, an opening for supplying or discharging air to or from the motor chamber can be provided.

A spur gear planetary gearing arrangement capable of a load balance on the teeth of the gears incorporated therein. The sun gear of the planetary gearing arrangement is supported solely on the planetary gears and the planetary gears are, in turn, rotatably supported on a planetary gear carrier. The teeth of the planetary gears are in meshing engagement with an internally toothed ring gear. The ring gear is mounted in a gear box housing. The ring gear is elastically deformable to a specific degree approximately equal with the radial electricity of its tooth system thereon and independent from the housing.

A nonsteerable drive mechanism for a watercraft which includes an upper part arranged within the watercraft and has a drive motor with a downwardly directed driving shaft. A lower part is arranged outside of the hull of the watercraft and has an angled gear arrangement, the driven shaft of which extends horizontally below the waterline in the lower part and has a propeller fixedly secured to its free end. The upper part is resiliently mounted to a base plate and the lower part, independently therefrom, is rigidly secured to the base plate. A fixed closure member closes off an opening through the hull and a part of the base plate encircling the opening of the watercraft, which closure member is sealingly penetrated through by a shaft connection connected to the angled gear arrangement. The power transmission from the upper part to the lower part takes place through an elastic coupling connecting the driving shaft to the shaft connection.

A friction clutch including interleaved compressible friction plates or overlapping conical rings and selectively operable structure effecting engagement thereof. One aspect of the invention relates to the structure for utilizing torque generated between the parts to be clutched for providing the compression force to be applied to the plates or the cone rings. Roller and ramp structure is provided between driving and driven parts responding to torque initially applied to the driving member for generating an axial force which is then applied to the clutch pack compressing structure. The roller has an elongated structure which will permit it to first roll about an axis perpendicular to the axis of rotation of the friction clutch and subsequently slide along its axial length. This structure will prevent or at least considerably reduce the power surges following a complete clutching operation.

Shiftable friction clutch in particular for gear drives

A double axle drive for railway trucks of rail vehicles. The axis of rotation of the drive motor extends parallel to the longitudinal axis of the vehicle and extends between the wheel-set axles. The drive motor drives the wheel sets through a bevel gear arrangement. Each bevel gear arrangement has, on the driven side thereof, a hollow shaft which encircles the respective wheel-set axle. The hollow shaft is connected at its two ends through an elastic coupling to the wheel-set axles. The entire drive system is supported on the two axles through four couplings. Each of the four couplings is composed of rotation-symmetrical members, one being connected to the hollow shaft and the other to the axle, and an interconnecting flexible joint sleeve circumferentially spaced around the periphery of the two coupling halves.
