RU237832U1 - Chassis for a vehicle with a cargo platform - Google Patents

Abstract

This utility model pertains to transport engineering, specifically to a chassis for a vehicle with a cargo platform, featuring front steerable drive wheels and rear drive wheels. The technical result achieved by this utility model consists of increasing the number of operating modes of a winch mounted on the chassis of a vehicle with a cargo platform. This result is achieved by the chassis for a vehicle with a cargo platform, which includes a frame with transmission components and assemblies mounted thereon, containing guide rollers that direct the cable both with and against the vehicle's travel, and a winch mounted on the frame crossmember, ensuring the cable passes over the deck of the cargo platform.

Description

The utility model relates to the field of transport engineering, namely to the chassis of vehicles with a cargo platform, with front driving steerable wheels and rear driving wheels.

The prototype of the claimed utility model is a chassis for a vehicle with a cargo platform (EP Patent No. 3173316, dated May 31, 2017), comprising a frame, transmission components and assemblies mounted on the frame, and a winch located at the front of the vehicle, below the radiator assembly. The winch cable extends forward of the vehicle via a guide roller. Thus, the winch, located at the front of the vehicle, is used to recover the vehicle when traversing difficult terrain in only one direction, relative to the vehicle's travel.

The disadvantages of the prototype are

the inability to self-extract a vehicle in two directions, in the direction of travel and against the direction of travel of the vehicle;

the inability to load heavy loads onto the vehicle's cargo platform using a winch.

The technical result achieved by the utility model consists of increasing the number of operating modes of a winch installed on a chassis for a vehicle with a cargo platform.

The specified result is achieved by the fact that the chassis for a vehicle with a cargo platform, including a frame with transmission units and assemblies installed on it, contains guide rollers that set the direction of movement of the cable both along and against the movement of the vehicle, a winch mounted on the crossbar of the frame, ensuring the passage of the cable over the flooring of the cargo platform.

The utility model provides for the use of a winch not only for self-extraction of a vehicle when overcoming difficult sections of the road both with and against the direction of the vehicle, but also for loading heavy loads onto the cargo platform of the vehicle.

The utility model is illustrated by drawings.

The chassis for a vehicle with a cargo platform comprises a frame (Fig. 1, item 4) with a gasoline engine (Fig. 1, item 1) mounted on it, with a cooling system (Fig. 1, item 11), working in tandem with a mechanical five-speed gearbox (Fig. 1, item 2). The torque from the gearbox is transmitted via a cardan shaft to the transfer case (Fig. 1, item 3), and from there the torque is distributed to the front (Fig. 1, item 8) and rear (Fig. 1, item 5) axles.

The chassis frame for a vehicle with a cargo platform contains a front (Fig. 1 pos. 9) and rear (Fig. 1 pos. 6) spring suspension with installed off-road wheels (Fig. 1 pos. 7).

The steering mechanism (Fig. 1 pos. 10) is attached to the frame via a bracket.

A winch with an electric drive (Fig. 2 pos. 12) is installed through the crossbar of the frame (Fig. 2 pos. 13) on the chassis for a vehicle with a cargo platform, which, depending on the design of the vehicle body, can be located under the passenger seat (Fig. 5 pos. 12).

For correct operation of the winch, guide rollers are installed (Fig. 2 pos. 14, 15, 16), which set the direction of movement of the cable.

Guide rollers, which set the direction of movement of the cable in the direction of movement of the vehicle, can be installed on the frame crossbar (Fig. 2 pos. 14), on the frame bracket (Fig. 2 pos. 15) and can be included in the design of the chassis power bumper (Fig. 2 pos. 16).

The winch cable with the hook passes through the guide rollers (Fig. 2, pos. 14, 15, 16) and is led out to the right side of the front bumper of the vehicle.

The direction of movement of the cable against the movement of the vehicle, namely over the flooring of the flatbed platform, for self-pulling of the vehicle against the movement or for facilitating the loading of cargo onto the flatbed platform, is ensured either by a guide roller installed at the rear (Fig. 3 pos. 17), which can be located either on the chassis for a vehicle with a cargo platform, or on other elements of the vehicle, or the direction of movement of the cable can be ensured by other structural elements.

In particular, a guide roller that sets the movement of the cable against the movement of the vehicle may be installed on the chassis of a vehicle with a cargo platform in the area where the cargo platform is installed and above the level of the cargo platform flooring.

The chassis for a vehicle with a cargo platform functions as follows: in the event of unforeseen situations during operation in severe off-road conditions, when the vehicle is unable to extricate itself, a winch is used. Guide rollers allow the winch to be used in both forward and reverse directions, and its location on the vehicle's crossbar allows the vehicle to be pulled out of various road surfaces. The winch can also be used for loading heavy loads onto the cargo platform (pulling them onto the platform).

If a single-drum winch is used, to self-recover the vehicle against the direction of travel or to load heavy loads onto a cargo bed, the winch cable is routed to the rear of the vehicle. To do this, first remove the hook from the winch cable by removing the cotter pin from the hook pin. The free end of the winch cable should be routed to the rear of the vehicle through the rear-mounted guide roller, then the hook should be reinstalled on the cable.

If a winch with two drums is used, the winch cable is routed to both the front and rear of the vehicle.
