Abstract
The present disclosure describes a gearshift mechanism for adjusting a gear ratio between a traction means, such as a chain, and a multi-sprocket gear set which can be rotated around an axle. The gearshift mechanism is configured to move the traction means in relation to the sprockets, such that an adjustment element is moved into the rolling motion of the traction means, thereby causing movement off of one sprocket and movement onto another sprocket.
Claims14
A gearshift for adjusting a traction means (140) on a gear set which can be rotated around an axle (4), the gear set including two or more sprockets (110, 120) around which the traction means (140) may loop, the gearshift comprising:
- at least one adjustment element that co-rotates with the gear set, wherein the at least one adjustment element is configured to be moved into a rolling motion of the traction means (140) to cause movement of the traction means (140) from one of the sprockets (110, 120) of the gear set to another of the sprockets (110, 120) of the gear set;
- wherein the adjustment element is pivotable around an axis of rotation that extends in a radial direction relative to the axle (4);
- and
- wherein the adjustment element comprises a switch (130) having a rotating shaft (320) that extends along the axis of rotation and wherein the switch (130) extends from a side of the rotating shaft (320).
A gearshift for adjusting a traction means (140) on a gear set which can be rotated around an axle (4), the gear set including two or more sprockets (110, 120) around which the traction means (140) may loop, the gearshift comprising:
- at least one adjustment element that co-rotates with the gear set, wherein the at least one adjustment element is configured to be moved into a rolling motion of the traction means (140) to cause movement of the traction means (140) from one of the sprockets (110, 120) of the gear set to another of the sprockets of the gear set (110, 120);
- and
- an electrical co-rotating control configured to adjust the adjustment element.
