Description

[0001] The invention relates to a track plate for a segmented wheel hub, which makes it possible to distance the wheel of a motor vehicle by means of this track plate, according to the preamble of claim 1.

[0002] A wheel spacer, also called a track widening plate, is designed for use between a wheel rim and the corresponding wheel hub of a motor vehicle. Such wheel spacers have been known for some time and serve, in particular, to widen the standard track width of a motor vehicle without modifying the wheel hub and without using special wheels or wheel hubs designed for a wider track.

[0003] This track plate is placed on the contact surface of the wheel hub, for which purpose it is provided with holes to accommodate the screws that hold the wheel to the wheel hub.

[0004] To center the wheel rim on the wheel hub, the wheel hub is provided in its center with a centering collar or individual circumferentially arranged centering ribs.

[0005] With known wheel spacers, the spacing is either correspondingly small, so that centering on the actual wheel hub is still possible, or correspondingly large, so that the wheel spacer can be centered on the wheel hub, which in turn enables the centering of the wheel.

[0006] There is currently no way to space wheels using wheel spacers by an amount that is only slightly less than or equal to the centering height of the wheel hub. This is primarily because the centering point for the wheel on the wheel spacer and the centering point of the base plate on the hub must have the same diameter.

[0007] From DE 195 07 773 A1 a track plate is known which has radial recesses on the inner diameter into which the wheel pins engage.

[0008] From the track plate, referred to there as a spacer, centering ribs project radially inwards into the central opening. The outer circumference of these ribs, together with that of the wheel hub's centering ribs, lies on a common, imaginary cylindrical outer surface, which, however, is not a closed ring. Such a ring possesses only limited stiffness, which is insufficient in many practical applications.

[0009] DE 195 07 773 A1 discloses a track plate with a base body with openings.

[0010] DE 299 08 651 U1 discloses a spacer washer with different sets of through holes for different sets of screw bolts.

[0011] The object of the invention is to overcome the disadvantages of the prior art and to provide a track plate which, in particular, makes it possible to space wheels by means of a track plate by an amount that is only slightly less than or equal to the centering height of the wheel hub. Furthermore, the stiffness of the track plate is to be increased in order to allow for higher loads.

[0012] The problem of the invention, which has existed for a long time without any third party being able to present such a solution, is solved by a track plate with the features according to claim 1.

[0013] This technical solution is implemented in a surprisingly simple way and is also suitable for mass use in industrial mass production.

[0014] The embodiment shown in the figures demonstrates that the track plate has a completely closed connecting ring, and several openings are arranged between the plate-shaped base of the track plate and the connecting ring. When the track plate is mounted and centered on the wheel hub, the wheel hub journals engage in and / or engage with these openings. The selected shape of a completely closed ring for the connecting ring significantly stiffens the wheel centering and thus opens up additional application possibilities.

[0015] The mounting points or openings in the track plate allow the track plate to be centered on the wheel hub pins of the wheel hub.

[0016] The track plate can be manufactured in the usual way, for example by forging or casting with subsequent usual finishing.

[0017] Dependent claims 2 to 10 contain advantageous embodiments of the invention without limiting it.

[0018] Preferably, the wheel hub journals engage axially from below on the connecting ring.

[0019] Alternatively, it is preferred that the outer contour of a wheel hub pin, in particular radially and laterally, engages in a recess 8 of an opening of the track plate in a form-fitting manner.

[0020] Alternatively, it is preferred that at least two of the wheel hub pins rest on the supports of the connecting ring and that the contour of the wheel hub pin, in particular radially and laterally, engages positively in the contour of one of the openings of the track plate.

[0021] The invention will now be explained in more detail with reference to the drawings, which do not limit it. They show: Fig. 1 a perspective view of a track plate attached to a wheel hub, and Fig. 2 a partial cross-sectional view through a track plate.

[0022] Fig. Figure 1 shows a perspective view of a track plate in an operating condition in which the track plate 1 is mounted on the wheel hub 2 in the usual manner and centered according to the invention.

[0023] The track plate 1 has a plate-shaped base body, which rests flat on the flat surface of the wheel hub 2 with one of its two outer surfaces and has five fastening points 4 distributed around the circumference, here designed as bores.

[0024] The track plate 1 has a central opening, with a closed connecting ring 7 arranged axially from the plate-shaped base body and spaced apart from the other of the two outer surfaces of the plate-shaped base body. Five webs 6 are arranged on the circumferential outer surface of the connecting ring 7, which serve to center the wheel (not shown in the figure).

[0025] The upper outer flat surface of the connecting ring 7 lies parallel to the two outer surfaces of the plate-shaped base body. The physical connection between the plate-shaped base body and the connecting ring 7 is made by five struts 5.

[0026] Between the struts 5 there is thus an opening, which is bounded by two adjacent struts 5 and in the axial direction by a flat support 9 of the connecting ring 7 and the plate-shaped base body. There are recesses 8 on the inner wall of the opening, in Fig. 1 not shown, arranged, into which the respective wheel hub pin 3 engages with its outer contour there in a form-fitting manner.

[0027] The wheel hub pin 3 rests against or engages with the flat support 9.

[0028] The holes at connection points 4 serve to attach the track plate 1 via screws passing through these holes. Fig. 1 not shown, to be placed on the wheel hub of a vehicle as a base for a wheel rim to be attached to the wheel hub.

[0029] Fig. Figure 2 shows a partial sectional view through a track plate 1 in an operating condition in which the track plate 1 is mounted on the wheel hub 2 in the usual manner and centered according to the invention.

[0030] This alternative design differs from the one in Fig.1. The embodiment shown is particularly distinguished by the fact that the wheel hub pin 3 does not engage with the flat support 9.

[0031] Recesses 8 are arranged on the inner wall of the opening, into which the wheel hub pins 3 engage in a form-fitting manner with their outer contour there.
