Two-wheeled vehicle with rear-wheel suspension
First Claim
1. A two-wheeled vehicle having a rear-wheel suspension arrangement, comprisinga) a frame with at least one frame tube;
- b) a swing arm assembly, which is mounted on the frame, for the suspension of a rear wheel;
c) a linear spring/damper element;
d) a transmission mechanism which is operatively connected at one side to the spring/damper element and at the other side to the swing arm assembly;
whereine) the spring/damper element is received in a receiving chamber within the frame tube; and
f) the transmission mechanism comprises a rotary axis which runs through an axial opening in the frame tube, the axis having an axle element being mounted so as to be rotatable in a bearing that is formed by an axial opening in the frame tube, wherein the transmission mechanism is designed, and mounted on the frame, such that it transmits a force between the spring/damper element and swing arm assembly via the rotary axis; and
whereing) the spring/damper element is articulated on the axle element eccentrically with respect to the rotary axis.

Abstract
The invention relates to a two-wheeled vehicle with rear-wheel suspension, comprising a frame (602) with at least one frame tube (603, 604, 605), a swingarm assembly (620) mounted on the frame (602) for the purpose of suspending a rear wheel (613), a linear spring/damper element, and a transmission mechanism (630) that is functionally connected to both the spring/damper element and to the swingarm assembly (620). The spring/damper element is received in a receiving chamber inside the frame tube (603). The transmission mechanism (630) is designed and mounted on the frame (602) such that it transmits a force between the spring/damper element and the swingarm assembly (620) by means of a rotational axis that extends through an axial opening in the frame tube (603). Arranging the spring/damper element inside the frame (602) avoids soiling. The rotational axis of the transmission mechanism (630) can also be designed to have relatively small dimensions in order to achieve a high degree of frame stability. In addition, the rotational axis can be arranged at different points in the frame and the spring/damper element can be housed in different regions of the frame in order for the transmission mechanism to be combinable with conventional rear-wheel suspension systems.
