Abstract
Abstract A rear wheel control unit for a two-wheeled vehicle with universal drive mechanism, such as a motorcycle, is disclosed. The rear wheel control unit comprises an axle housing for accommodating a drive unit of the universal drive mechanism of the two-wheeled vehicle in operative connection with the rear wheel of the vehicle. The axle housing has a connecting member for accommodating a shaft of the universal drive mechanism and is pivotably mounted to the frame of the two-wheeled vehicle by first and second wheel control arms arranged in a four-bar linkage. The first wheel control arm is formed as a one-armed oscillating lever articulated on the wheel side with the connecting member of the axle housing. The second wheel control arm serves as a moment support member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A rear-wheel control for two-wheel vehicles, especially a motorcycle, comprising a driven wheel controlled by a one-armed oscillating lever pivoted at the frame and connected to a gear wheel and pinion of a ring/gear pinion gearing so that the driven wheel is fixed with respect to rotation, the gear wheel and the pinion being disposed in an axle housing relative to the one-armed oscillating lever by means of an arm and a moment support flexibly connected to said arm and the frame, said housing adapted to be pivoted, the pinion being disposed so that said pinion is aligned with the one-armed oscillating lever at the connecting member of the housing, said pinion being connected to a universal shaft arranged in said lever, said universal shaft, in the area of the pivot point of said lever at the frame, being provided universal joint means and the lever is also flexibly connected to the housing.
Claim 2
Dependent Claim
153 words
A rear-wheel control for two-wheel vehicles, especially a motorcycle, comprising a driven wheel controlled by a one-armed oscillating lever pivoted at the frame and connected to a gear wheel and pinion of a ring/gear pinion gearing so that the driven wheel is fixed with respect to rotation, the gear wheel and the pinion being disposed in an axle housing relative to the one-armed oscillating lever by means of an arm and a moment support flexibly connected to said arm and the frame, said housing adapted to be pivoted, the pinion being disposed so that said pinion is aligned with the one-armed oscillating lever at the connecting member of the housing, said pinion being connected to a universal shaft arranged in said lever, said universal shaft, in the area of the pivot point of said lever at the frame, being provided universal joint means and the lever is also flexibly connected to the housing.
Claim 3
Dependent Claim
40 words
A rear wheel control unit according to claim 1, wherein means are provided for covering the point of articulation of the one-armed oscillating lever at the connecting member of the axle housing means, said means for covering is a bellows.
Claim 4
Dependent Claim
38 words
A rear wheel control unit according to claim 1, wherein said axle housing has a bracket for connecting a shock absorber means thereto and an arm for the connection of the moment support member to said axle housing.
Claim 5
Dependent Claim
40 words
A rear wheel control unit according to claim 1, wherein the connecting member is arranged separately at the axle housing and is equipped with brackets for connecting a shock absorber means and the moment support member to said axle housing.
Claim 6
Dependent Claim
44 words
The rear-wheel control according to claim 1, wherein the housing has a connecting member and said connecting member is connected to said lever, and means being provided for the tight covering of the pivoting point which tightly enclose the connecting member and said lever.
Claim 7
Dependent Claim
212 words
A rear-wheel control for two-wheel vehicles, especially a motorcycle comprising a driven wheel being controlled by a one-armed oscillating lever pivoted at the frame and connected to a gear wheel and pinion of a ring gear/pinion gearing so that the driven wheel is fixed with respect to rotation, the gear wheel and the pinion being disposed in a housing relative to said oscillating lever by means of an arm and a moment support that is flexibly connected to said arm and said frame, said housing adapted to be pivoted, the pinion being disposed so that said pinion is aligned with the oscillating lever at the connecting member of the housing, said pinion being connected to a universal shaft arranged in said lever, said universal shaft, in the area of the pivot point of said lever at the frame, being provided universal joints means, the lever being connected with the housing and that a moment support member is arranged in its pivot point within a slotted oblong hole, and the moment support member adapted to be transversely moveable with respect to said lever so that said moment support member is movable and lockable in said slotted oblong hole, and said moment support member can be variable in its length between the pivoting points.
