A device for mounting the wheel on the hub (Fig. 1) is mounted on the hub 1, to which the brake disk 2 is connected. The device is mounted on the hub 1 using the fastening means 3 (nuts or bolts) and is used to connect the wheel rim 4 to the hub 1. The device includes an adapter 5 having a disk connected to the hub 1 and a protruding part made at the same time with the disk (Figs. 3-7). In the adapter disk 5, holes 6 are made for the fastening means 3, pressing the adapter disk 5 to the hub 1. On the adapter disk 5, pins 7 are installed on the outside of the adapter, located in the holes 8 of the wheel rim 4 when it is mounted on the hub 1. On the protruding part of the adapter 5 from its outer side there is a thread 9 (Fig. 3), and at the end of this part there are a lot of protrusions 10, between which there are recesses 11 under the latch 12 (Figs. 1, 2).

The pins 7 (Fig.11-13) are located with the possibility of their free entry into the holes 8 of the rim 4 of the wheel (Fig.1). The thread 9 of the protruding part of the adapter 5 is made under the thread 13 of the castellated nut 14 interacting with it (Figs. 8-10), screwed onto the protruding part of the adapter 5 and secured to it by the latch 12. At the outer end of the nut 14 there are many protrusions 15, between which recesses 16 are located under the latch 12. The nut 14 is externally made conical for its conical surface 17 to interact with the mating landing conical surface 18 of the wheel rim 4 (FIGS. 1, 21). In the working position of the device, the recesses 16 of the nut under the latch and the recesses 11 of the protruding part of the adapter 5 are aligned and the latch 12 is located in them (Fig. 21).

The latch 12 (Fig.14-17) is made in the form of a figured plate with a Central hole 19 in its more developed middle part, and tapered ends 20 on the peripheral parts, and the tapered ends 20 of the plate should be located in opposite recesses 16 of the nut and combined opposite the recesses 11 of the protruding part of the adapter 5 (Fig.1, 2). The latch 12 interacts with the plug 21 (Fig. 18-21) having a centering protrusion 22 that is included in the Central hole 19 of the latch in the working position of the device, and the plug 21 has a means 23 of its fixation in the cavity of the protruding part of the adapter 5.

In the cavity of the protruding part of the adapter 5, an inwardly extending belt 24 (Fig. 3) is made for interacting with it of the means 23 (Fig. 19, 20) for fixing the plug 21 (Fig. 2). Each tool 23 is made in the form of an elastic protrusion with a beard 25 at the end (Fig. 18-20), interacting with the belt 24 of the protruding part of the adapter in the working position of the device.

Each pin 7 is fixed in the adapter hole 26 (FIG. 2), inside the pin 7 (FIGS. 11–13) there is a recess 27 with key faces 28, and on the outside the pin has a belt for fixing the pin on the adapter disk 5 in the working position. The pin 7 has a thread 29 at the end and it is preferably screwed into the adapter hole 26, otherwise the pin has a smooth end and is pressed into the hole 26 with its smooth fitting part (not shown). The belt 30 of the pin 7 is located approximately in the middle of the pin.

Installation of the device is as follows. Connect the adapter 5 to the hub 1 by means of 3 connections (figure 1). The pins 7 are fixed on the adapter disk in the holes 26 of the adapter (Fig. 21). Put on the pins 7 of the rim 4 of the wheel by inserting the pins 7 into the holes 8 of the rim (figure 1) and screw the nut 14 on the thread 9 of the protruding part of the adapter. In this case, the conical surface 17 of the nut interacts with the conical surface 18 of the rim 4, the rim is centered on the adapter and pressed against the disk of the adapter 5. The nut 14 is screwed with a removable (not included in the device structure) toothed head 31 (figure 2, 21), the teeth 32 of which the nuts 14 are inserted into the recesses 33 (Figs. 8-10). The head 31 is rotated with a key (not shown) inserted into the faceted hole 34 of the head. The rotation of the head 31 is carried out until the recesses 16 of the nut 14 are aligned with the recesses 11 of the protruding part of the adapter 5 (Fig.1, 2). After the wheel rim 4 is pressed to the adapter disk 5 and the indicated recesses are combined, the ends 20 of the latch 12 are located in these recesses, which occupies the position shown in Figs. 1, 2 and 21. Then, the end of the protruding part of the adapter 5 is closed with a plug 21, for which the centering the protrusion 22 (Fig. 19) of the plug is inserted into the hole 19 of the latch 12 (Fig. 2) and move with effort, a light blow, the plug 21 towards the adapter 5. As a result of the fixing means 23, the plugs are bent to the central axis of the adapter, and the beards 25 of these funds are engaged with the belt 24 of the adapter. Dismantling is carried out in the reverse order.

The device operates as follows. When the wheel hub rotates, the torsion force is transmitted to the fastening means 3 (pins or bolts), from them to the adapter 5, from the adapter to the pins 7, and from the pins 7 to the wheel rim 4. In this case, the pins 7 take on the main torsion load and work on a cut, and the connection means 3 work mainly on separation. When the sign of the torsion moment changes to the opposite sign, for example, when the disk 2 is braked, the indicated loads change their direction.

This device improves the reliability of the connection of the rim with the hub and allows you to change the reach of the rim 4 of the wheel relative to the hub 1, as well as relative to the longitudinal axis of the car, by the thickness t of the adapter disk (Fig. 3), which allows you to install a wheel with a wider rim and tire on the car hub another profile. If necessary, install another adapter, with a different, larger or smaller thickness t of the disk and get another departure of the wheel rim relative to the hub and the longitudinal axis of the car. Taking into account the safety requirements, it was found that the increase in the reach for cars is possible by 5-40 mm, which significantly expands the possibility of using different tires with different wheel rim profiles on the same model of car. This significantly increases the versatility of the device.

The design of the device is greatly simplified due to the special orientation of its thread, eliminating the loosening of the nut, since the device uses the more reliable, relatively well-known analogues, principle of its fixation in the working position.

Due to the simplification of the design of the device, its reliability is increased and the possibility of reliable fastening to standard hubs of many sizes of wheels with different profiles of rims and tires is provided.
