Apparatus for storing the braking energy of a vehicle, in particular of a bicycle

摘要

Apparatus for storing the braking energy of a vehicle, in particular of a bicycle, for mounting in a wheel which has a stationary axle (10) and a hub casing (12) which rotates about the axle (10) and bears the wheel rim, if applicable via spokes, a spiral spring (14) which takes up the braking energy and means for selecting the operating positions "normal", "brake", "accelerate" with couplings which can be engaged and disengaged and at least one freewheel, an axle sleeve (16) which is arranged adjacent to the axle (10) so as to be rotatable about the latter and a hub sleeve (18) which is arranged adjacent to the hub casing (12) being provided, the inner end of the spiral spring (14) being fixedly connected to the axle sleeve (16) and the outer end of the spiral spring (14) being fixedly connected to the hub sleeve (18), and the means for setting the operating positions having a coupling (20) between the axle (10) and the axle sleeve (16) and a coupling (22) between the hub casing (12) and the hub sleeve (18), which are engaged in the operating position "brake", a freewheel coupling (24) between the hub casing (12) and the axle sleeve (16) and a coupling (26) between the axle (10) and the hub sleeve (18), which are engaged in the operating position "accelerate", and a freewheel coupling (28) between the axle sleeve (16) and the hub sleeve (18), which is disengaged in the operating position "accelerate". <IMAGE>
