It is known that the dismantling of the wheels of motor vehicles,

for example, as a result of a flat tire, is an often tedious process for the driver of the vehicle. The tightening of the screws that fix the wheel on the corresponding stub axle has mostly been carried out by a specialist who has improved tools that are able to develop a considerable expenditure of force, which is greater than that which the driver uses on board the vehicle can exercise the tool accessories. In addition, this first tightening and holding of the loading | fixing screws under increased angular momentum by the in \ rolling of the vehicle on the screws applied rotational effect and the more or less strong oxidation of the threaded bolt.

The object of the innovation is a device to simplify the removal process listed above, so that it can be used by everyone Motor vehicle driver is feasible "

The device according to the innovation is essentially characterized in that it contains a housing which has a reduction gear encloses, the drive pinion is designed so that it is in motion with the help of a suitable tool can be set, while the output pinion is firmly connected in the direction of rotation with a socket, which is the Can adjust the fastening nuts of the wheels in use. The housing is provided with a tilt stand that is inclined on the floor to determine the arrangement against twisting.

The attached drawing with an embodiment allows a better understanding of the innovation, its features and of the advantages to be offered by it, namely shows

Fig. 1 shows a removal device according to the innovation in the operational position on the wheel of a vehicle and

Fig. 2 is an axial section of the housing of this device on a larger scale.

In Fig. 1, the reference numeral 1 denotes the wheel of a vehicle, its rim 2 on the corresponding axle journal with egg fastened by nuts 3 screwed onto suitable threaded spindles is. The device according to the innovation essentially comprises a housing 4, a key 5 and a tilt stand 6 are assigned.

In * "ig. 2 it is assumed that the housing 4 consists of two Flanges 7 is composed of a round profile, which are connected to one another by a cylindrical center piece 8. These flanges 7 support two shaft ends 9 and 10 which are directed parallel to the general axis 4 of the housing 4; A small pinion 11 is wedged on the shaft end 9, which meshes with a large pinion or gear wheel 12, which on the Shaft end 10 is keyed. The latter is firmly connected to a socket 13 which is arranged outside the housing 4 and is profiled so that it can be fitted or slipped onto the nuts 3 of the wheel 1; otherwise is on the opposite side of this socket 13, the shaft end 9 extended in the form of a ferrule 14, which receive the operating key 5 suitable is.

To the räuiichen extent of the device on Transportscellen To reduce, the tubular support of the center stand 6 is advantageously releasably attached to the housing 4. For this purpose one can As shown, place a sleeve 15 on the housing 4, onto which one of the ends of the pipe support 6 is then pushed can.

The use and operation of the device according to the innovation are easy to understand. Holds to remove the wheel the operator adjusts the housing in such a way that the socket 13 is pushed onto one of the screws 3. He then pushes the pipe support 6 so in the sleeve 15 that it is in the direction of the rear

The end of the vehicle touches the ground. It is then sufficient to close the clamp 14 with the aid of the removable key 5 rotate.

¹ T It is evident that the device 11-12 has a considerable

j Reduction causes, in such a way that a relatively small,

Force exerted on the key 5 in the amount of Socket 13 is implemented in a very large effort. The loosening of the nuts 3 is so easy to carry out, which The nature of the degree of clamping and the physical strength of the user of the device. Besides is too note that the device can also be used to reinstall the wheels, although it has less advantages for this offers and is then conveniently operated in such a way that any excessive tightening of the nuts 3 is taken into account the achieved reduction is avoided, as with the operation of the usual jacking winch.

Of course, the above description is only given by way of example required. It does not restrict the innovation area in any way and does not exceed its scope, if the described execution details by other equivalents be replaced. In particular, it is possible that the built-in reduction gear in the housing 4 from any Number of pinions can exist.
