Definitions
- the invention initially relates to a hub arrangement for a hub for a bicycle wheel according to the preamble of claim 1.
- the hub assembly comprises: a) an axle and a hub body, the axle extending through the hub body in a longitudinal direction, the hub body being rotatably mounted relative to the axle via at least one roller bearing, and an inner ring of the roller bearing being arranged on the axle and an outer ring of the roller bearing is arranged on or in the hub body, with a bearing section of the hub body facing the roller bearing viewed in the longitudinal direction being arranged on the outer ring of the roller bearing, and b) an end body which is on the side of the roller bearing facing away from the hub body is fixed to or on the axle, with a bearing section of the end body facing the roller bearing viewed in the longitudinal direction being arranged on the inner ring of the roller bearing.
- the invention according to claim 30 relates to a compensating element for a hub arrangement, according to claim 31 to a hub for a bicycle wheel with a hub arrangement, and according to claim 34 to a bicycle wheel with a hub.
- EP 2 559 569 A2 shows in FIGS. 3 and 6 a hub assembly and a hub (rear wheel hub) for a bicycle wheel.
- the axis of the hub arrangement has a shoulder in each case towards the inside, against which the inner ring of the roller bearing rests. This means that the inner ring cannot migrate on the axle in the direction of the inside of the hub assembly.
- Such an arrangement can therefore be described as having little or no play.
- the position of the brake disc and sprocket set changes only slightly in relation to the respective counterparts, brake pad and rear derailleur, depending on a possible compression of the axle, which promotes precise shifting and friction-free brake operation.
- the roller bearings can tend to be stressed here when the impeller is installed, which can lead to increased friction and more wear.
- the object of the present invention is to overcome the disadvantages arising from the prior art.
- the object is to achieve a light and low-wear operation in the aforementioned hubs for bicycle wheels with reduced play and a reduced tendency to vibrate at the same time.
- the hub arrangement is further developed in such a way that a compensating element is arranged between the bearing section of the end body and the inner ring of the roller bearing and/or between the bearing section of the hub body and the outer ring of the roller bearing, which has a variable expansion seen in the longitudinal direction.
- a compensating element according to claim 30 for a hub arrangement according to the invention also contributes to solving the above-mentioned problems.
- the compensating element is able to improve the shifting and braking performance, because the position of the brake disc and the sprocket set does not change as much as with a hub arrangement that is subject to play. This minimizes the occurrence of shifting errors and grinding brake discs.
- the compensating element has a vibration-damping effect and minimizes vibrations, which is very beneficial when braking, shifting gears and traction.
- the change in width of a gap, usually between the end body and the inner ring of the roller bearing, due to compression of the axle by the quick release or the quick-release axle, can be compensated for by the compensating element. This prevents the roller bearing from being distorted or even destroyed, without the axis being able to move back and forth unhindered due to the presence of a gap.
- the inner side is understood to mean the side facing the interior of the hub arrangement, viewed in the longitudinal direction (axial direction).
- the outside is understood to be the side facing the outside of the hub arrangement, viewed in the longitudinal direction.
- the inner ring of the rolling bearing is - as usual - of the two Bearing rings always use the ring of the roller bearing with the smaller diameter.
- the outer ring of the bearing is always the ring of the bearing with the larger diameter.
- a hub body within the meaning of the present invention is understood to be a body which is mounted via at least one roller bearing so that it can rotate with respect to the axis of the hub arrangement and through which the axis extends in a longitudinal direction.
- this relates to a body conventionally referred to as a hub body, to which the spokes of the impeller are fastened.
- an optional body which is more conventionally referred to as a freewheel body, is also understood as a hub body.
- the hub body to which the spokes are assigned can be referred to as the first hub body, while an optional freewheel body can be referred to as the second hub body.
- a freewheel body is usually associated with a hub arrangement or a hub for a rear bicycle wheel and serves to accommodate a power transmission means, in particular a sprocket set.
- a first and a second hub body are arranged next to one another, viewed in the longitudinal direction of the axle. Furthermore, the rotation of the second hub body (freewheel body) can be decoupled from the rotation of the first hub body.
- a first hub body is usually mounted so as to be rotatable relative to the axle via two roller bearings spaced apart from one another, and an optional second hub body (freewheel body) is usually mounted so as to be rotatable relative to the axis via two further roller bearings spaced apart from one another.
- a rolling bearing within the meaning of the present invention is understood to mean a bearing which is suitable for the rotatable mounting of a hub body relative to the axis of a hub arrangement under discussion here and which has an inner ring and an outer ring. Therefore, in the present case, in addition to conventional roller bearings with roller bodies, plain bearings and, in particular, spherical plain bearings, which correspond to this definition, are summarized under the term roller bearing, even if such bearings are not usually referred to as roller bearings.
- the aspects according to the invention are discussed further below, for which purpose reference is made in part to non-limiting advantageous configurations and developments of the invention. The features of advantageous developments can be realized individually or in any combination, whereby further advantageous developments of the invention are created.
