Definitions
- the invention relates to an impeller assembly with a hub device and an impeller which is rotatably mounted on the hub device.
- Such wheel assemblies are used, inter alia, in sports equipment, such as inline skates.
- Such wheel assemblies consist in particular of a wheel body, for example made of polyurethane, and a rim firmly connected to this wheel body.
- the rim is in turn rotatably mounted on a hub.
- the hub is attached to a bracket provided on the inline skates by means of an axle.
- a disadvantage of this known wheel arrangement is that impacts on a single wheel of the inline skates cannot be cushioned, but rather are transmitted to the inline skate. Such impacts reduce driving comfort and also lead to heavy stress on the joints.
- the known wheel arrangement tends to vibrate, particularly at high running speeds.
- the object of the invention is to improve the known wheel arrangements.
- a wheel arrangement of the type mentioned at the outset which is characterized in that the hub device has an inner hub and an outer hub which are provided in a substantially rotationally fixed manner and displaceable in the radial direction relative to one another, and a spring device which is provided between the inner hub and the outer hub is included.
- the hub device according to the invention comprises an inner hub, which can be connected to the inline skate by means of an axle, and an outer hub, which is provided in a rotationally fixed manner with respect to the inner hub and can be moved in the radial direction relative to the same, the wheel arrangement can be essentially perpendicular to the Move inline skate.
- the spring device which is provided between the inner hub and the outer hub, can finally cushion impacts against individual wheel arrangements of the inline skates in the direction of movement of the wheel arrangement with respect to the inline skate. This increases driving comfort while protecting the joints of the inline skater.
- vibrations of the wheel arrangement are reduced, particularly at high speed.
- the outer hub can be provided in the inner hub so as to be movable in the radial direction. This avoids a possible tilting in the case of obliquely occurring forces, which occur in particular when driving with inline skates.
- the axes of the outer hub that is to say the axis of rotation of the impeller, and the fastening axis of the inner hub can be parallel and offset from one another.
- the spring device can be designed in the form of an elastic body, preferably made of PU foam.
- Such a spring device is very simple to manufacture, which ultimately leads to an inexpensive implementation of the wheel arrangement.
- the damping can also be adjusted by a suitable choice of material. It is thus possible to optimally adapt the wheel arrangement to corresponding driving situations, for example on the road or on terrain, and to adapt it to the body weight of the inline skater.
- the elastic body can in this case have an opening, that is to say it can be ring-shaped. It is then possible to provide the inner hub with a section for positive engagement in the opening of the elastic body, and to provide the outer hub with a section for positive engagement of the elastic body.
- both sections are expediently designed such that the essentially rotationally fixed arrangement of the inner hub with respect to the outer hub is ensured by the elastic body used.
- the outer hub can have a section for form-fitting engagement in the opening of the elastic body
- the inner hub can have a section for the form-fitting reception of the elastic body, both sections being designed such that the essentially rotationally fixed arrangement of the Inner hub is ensured with respect to the outer hub.
- the spring characteristics of the wheel arrangement in particular the spring strength and the spring travel, can be adjusted by the shape of the opening in the spring element and the shape of the corresponding engagement section, and can thus be adapted to given situations.
- the inner hub can have two halves which can be plugged into one another in the axial direction in such a way that they are provided in a rotationally fixed manner.
- the halves can have claws for forming a rotationally fixed coupling of the two halves.
- the outer hub can also have two halves.
- the spring device can comprise a first spring element and a second spring element, the first spring element being provided between one half of the inner hub and one half of the outer hub, and the second spring element being provided between the other half of the inner hub and the other half of the outer hub.
- This symmetrical arrangement ensures an even distribution of force on the axis of the inline skates. This ultimately leads to the fact that the wheel arrangement of the inline skate is more robust and wears out more slowly.
- this arrangement also corresponds to the structure of the conventional wheel arrangements for inline skates, so that retrofitting conventional inline skates with the wheel arrangements according to the invention is possible without any problems.
- an impeller with a wheel body and a rim firmly connected to it is used.
- the rim By attaching the rim to a bearing device, it is possible to form the bearing between the impeller and the outer hub in a simple manner.
- the rim can advantageously have a web with openings in the radial direction. The wheel center can then be cast around the web and the openings. This ensures a stable attachment of the wheel body to the rim.
- the rim is expediently rotatably supported on the outer hub by means of a ball bearing or a goods store.
- Such bearings represent particularly reliable and inexpensive storage facilities.
- the rim can advantageously be secured to the ball bearing or the roller bearing by means of a securing ring. Since such a circlip can be easily attached and detached, this measure also ensures simple assembly. This makes it possible to exchange individual components, for example the storage device.
- FIG. 1 shows a cross section of a wheel arrangement according to the present invention
- FIG. 2 shows a plan view of one half of an inner hub of the wheel arrangement according to FIG. 1, and
- FIG. 3 shows a plan view of a spring body of the wheel arrangement according to FIG. 1.
- Fig. 1 shows the cross section through a wheel assembly according to the present invention.
- This wheel arrangement comprises a hub device 10 and an impeller 50 which is rotatably mounted on the hub device 10.
- the hub device comprises an inner hub 20 and an outer hub 30. Both the inner hub and the outer hub 30 each consist of two halves, i.e. of two inner hub halves 21 and 22 and two outer hub halves 31 and 32.
- a spring element 41 is provided between the first inner hub half 21 and the first outer hub half 31.
- a spring element 42 is arranged between the second inner hub half 22 and the second outer hub half 32.
- the spring element consists of an elastic body 41 which has an opening 42.
- the inner hub half 21 shown in plan view in FIG. 2 comprises a circular and plate-shaped section 24.
- This circular and plate-shaped section 24 is followed by a section 23 which has a shape which corresponds to the opening 42 in the elastic body 41.
- the section 23 of the inner hub 21 and the opening 42 of the elastic body 41 are formed such that the section 23 engages in the opening 42 in a form-fitting manner.
- another extension 26 which, as can be seen in particular from FIG. 1, is claw-shaped.
- the claws 26 are provided so that they are non-rotatably engaged with a claw 26 'of the second inner hub half 22 when the wheel arrangement is mounted.
- a bore 27 extends through section 26, through which an axis for fastening the wheel arrangement to the inline skate can be guided.
- the special configuration of the opening 42 in the spring element 41 and the section 23 of the inner hub half 21 ensures an essentially rotationally fixed arrangement of the outer hub with respect to the inner hub 21. Consequently, when the wheel arrangement is installed in the inline skate, the outer hub arrangement 30 is also provided in a rotationally fixed manner with respect to the inline skate, so that the impeller 50 can be freely rotated with respect to the inline skate by means of a bearing device 60.
- the outer hub device 30 has to be attached essentially non-rotatably with respect to the inner hub device 20 (and the inline skate firmly connected thereto), it immediately follows how the engagement section 23 of the inner hub half 21 and the corresponding opening 42 of the elastic body 41 are designed have to. With respect to the elastic body 41, the shape of the opening 42 should therefore deviate as much as possible from a radial symmetry. Accordingly, as an opening
- the inner hub halves 21 and 22 are designed such that they have a guide section for the two outer hub halves 31 and 32.
- This guide section is designed such that guidance of the outer hub device 30 in the inner hub device 20 in the vertical direction in FIG. 1 is possible.
- the spring elements 41 and 42 due to the spring elements 41 and 42, this movement is not free, but rather only damped. As a result, shocks applied to the wheel assembly in the vertical direction can be dampened by the spring members 41 and 42.
- the strength of the damping and the spring travel can be used here one by the material used for the spring element 41 and the other by the shape of the opening 42 in the spring element 41.
- the eccentric shape of the opening 42 of the spring element 41 means that the axis 35 of the outer hub device, that is to say the axis of rotation of the impeller, is offset with respect to the fastening axis 35.
- the eccentric asymmetrical shape of the opening 42 in the spring element 41 also leads to the spring element 41 having a wide section 45 and a narrow section 44.
- the wheel assembly is attached to the inline skate so that the narrow portion 44 faces the inline skate while the wide portion 45 faces away from the inline skate. As a result, the spring travel can be increased with the same size of the wheel arrangement.
- the spring element 41 comprises lateral sections 46, which are also thicker than the section 44, these sections ensure that not only shocks are damped, which are given perpendicularly from below to the wheel arrangement built into an inline skate, but also shocks that are placed on the wheel assembly at an angle to the vertical.
- the two outer hub halves 31 and 32 are designed so that they can accommodate a ball bearing.
- the impeller 50 is rotatably supported on the outer hub device 30 by means of this ball bearing.
- the impeller 50 is expediently formed from a wheel body 51 and a rim 52.
- the rim 52 comprises a web 53 which is provided with openings, one of which is shown in FIG. 1 and is designated by the reference number 54.
- the wheel body 51 is cast around the web and through the openings. In this way, a firm connection between the wheel body and the rim can be ensured.
- the fig 51 is in turn provided with a recess for receiving the ball bearing 60.
- the bearing is expediently secured to the rim by a locking ring 55. This makes it possible for the components of the wheel arrangement to be easily assembled and disassembled.
