Device for delivery motion switch to bicycle driving device

Abstract

The invention relates to the transmission of switching movements into a multi-speed transmission. The switching rod or a steel cable section is introduced into the sleeve drive from the outside, ie between the wing and the outer end of the frame, through an opening extending axially between the bearing cone and the shaft. The linear switching movement on the cable is thus transmitted directly and without conversion to the transmission. In order to guide the steel cable in the sleeve, a groove is provided on the bearing cone and / or on the inner diameter of the bearing cone. The cables are deflected from the axial direction to the frame into cable guide grooves of convex profile on a fixed element, preferably on the bearing cone or on the shaft.

Description

technical field

[0001] The invention relates to a device for introducing and subsequently transmitting a shifting movement in a bicycle transmission, in particular to a device for axial displacement of transmission and clutch elements in a multi-speed sleeve transmission according to the preambles of the independent claims installation. Background technique

[0002] A multi-speed sleeve is formed from at least one planetary gear set arranged around the fixed shaft. The rotational torque is transmitted via a wing to the drive and via one of the transmission paths of the planetary gear to the sleeve housing. The corresponding selected transmission path is implemented by a component of the transmission, which rotates or moves relative to the shaft. The gear is selected via a switch in the region of the guide rod and is further guided, for example mechanically, by a linear movement of a steel cable to the multi-speed sleeve. The shifting movement corresponding to the selected...
