Description

Description of the invention

The utility model refers to the bodies of passenger motor vehicles of general use 2 (buses) and other motor vehicles, in particular to devices for installing and securing their spare wheel.

A known device for installing and securing a spare wheel on vehicles (US patent

Mo4174797 dated 20.11.1979 Or., patent of Ukraine Mob7849 C2 dated 15.07.2004, which contains a spare wheel holder, equipped with guide rollers to facilitate the movement of the holder with the wheel along rectangular guide 70 profiles for installation and fastening in the compartment of the vehicle body.

Disadvantages of these devices are a fairly complex design and the inconvenience of carrying out the operation of dismounting and mounting the spare wheel on the device and its attachment to the vehicle body, which is connected with the placement of the device in the lower part of the bus body.

The basis of the useful model is the task of improving the design of the device for installing and fastening 72 spare wheels in a special compartment of the bus body, reducing effort and laboriousness, and improving the ease of carrying out operations on dismounting and mounting the wheel on the holder and its attachment to the frame of the bus body.

The essence of a useful model is as follows. In order to improve the convenience of removing and installing the wheel on the holder and attaching it to the frame of the bus body, the spare wheel holder is installed horizontally in a special compartment of the bus body on the right or left side above the wheels of the rear drive axle. Access to the holder is provided through a door, respectively, in the right or left side panels. In order to simplify the design of the holder and reduce the forces applied during disassembly and assembly of the wheel on the holder and its installation and fastening to the frame of the bus body in the transport position, the holder is connected to the frame of the bus body by rollers that move along horizontal 22 guide profiles and horizontal hinges that ensure rotation of the holder up to the stop with the surface of the road surface for dismounting and mounting the spare wheel on the holder. At the same time, the maximum force required for lowering the holder and its subsequent lifting and fixing in the bus body is reduced by 2 times. Thus, the design and place of installation of the spare wheel holder ensure the driver to perform the necessary operations when replacing the spare wheel in the most convenient positions - vertical for the initial and final operations, and in a bent state on the side of one or another side of the bus body when disassembling and installing the wheel on the holder

The location of the device for installing and fixing the spare wheel in the engine compartment of the bus and its M design are shown in the drawings, where on: Ge)

The device for installing and fastening the spare wheel 1 (see Fig. 1 and 2) contains a holder 2 of the spare wheel c, which is installed in the guide frame, placed in the compartment above the wheels of the driving bridge of the bus, which is accessed through the door 3. In the transport position the spare wheel is installed on the holder horizontally, i.e. parallel to the road surface. The spare wheel holder consists of two 29 risers 4 (see Fig. 3-9), each of which is made of five sections of pipes of rectangular section, which are rigidly connected to each other by tubular crossbars 5, 6 and 7 of rectangular section using a welded connection. In the middle part, the risers are rigidly connected by crossbar 8 of channel section. The wheel through any two opposite holes of attachment to the hubs of the front axles or rear driving axles is installed on two bolts 9, which are welded to the crossbar 8 and fixed with nuts 10 (see Fig. 10-12). The spare wheel holder 60 in the rear part is equipped with rollers 11, which are placed on the sides of the risers and can freely rotate around the axes 12, which are screwed to the risers. In the front part of the holder, two handles 13, made of a round pipe, are welded. Two rubber buffers 14 are installed in the crossbar 7 on the outside, designed for gapless fastening of the spare wheel holder to the guide frame 15 (see Fig. 10-15), welded to the frame 16 of the bus body. The spare wheel holder can freely move perpendicular to the longitudinal axis of the bus on the rollers 11, which move in the guide grooves formed by the corners 17, and on the rollers 18, which are screwed near the sidewall to the longitudinal elements 19, made of a rectangular pipe. The spare wheel holder in the transport position is fixed to the frame of the bus body with bolts 20 through brackets 21 of the channel profile, which are welded to the longitudinal elements 15 of the guide frame.

The device for installing and securing the spare wheel in the compartment above the wheels of the bus drive bridge works as follows. When it is necessary to replace the spare wheel, the driver opens the door C (see Fig. 1) in the side panel to access the compartment in which the spare wheel holder is installed, and unscrews two bolts 20 of the holder's fastening to the guide frame, which is welded to the frame of the bus body. After that, the driver, applying the necessary force to the handles 13, pulls the holder from the compartment to the stop in the brackets 21 and lowers it around the 7/0 horizontal axis of the fingers 12 until the holder rests on the road surface 22 (see Fig. 16).

Next, the driver unscrews the nuts 10 and, lifting the spare wheel 1, removes it from the holder 2. The damaged wheel is installed on bolts 9 and fastened with nuts 10. Next, the holder is lifted by the driver, installed horizontally in the compartment to the stop of the rubber buffers 14 in the brackets 23 welded to the guide frame, and is fixed with 20 bolts.

The device for installing and fixing a spare wheel in the engine compartment of bus bodies, which is claimed, is characterized by a fairly simple design and ease of use, contributes to a significant reduction in time and physical costs for removing or installing a spare wheel on its fastening bolts, since the driver when performing these operations is in a more advantageous position. In addition, the installation of a spare wheel in the compartment above the wheels of the driving bridge of the bus ensures the achievement of larger trunk volumes, which is especially important for buses intended for intercity and tourist transportation of passengers.
