The utility model relates to the chassis of trucks designed to install various add-ons on them.

A car chassis is known, made with a 6x4 wheel arrangement with certain geometric parameters, equipped with a front-folding hinged cab under which it is placed; an engine, a frame with front and rear overhangs, a five-speed gearbox (certificate of the Russian Federation No. 2790, IPC V 62 D 21/00 61/10).

The closest in terms of land; natural features to the claimed technical solution is a three-axle truck chassis (two options), made with a 6x4 wheel arrangement, with geometric parameters: A / (B + A) 1.70 (1.62); C / (B + C) 0.38 (0.30), where A is the overall length of the chassis;

B - the distance between the axles of the front and middle axles; B is the distance between the axles of the middle and rear axles; C - rear overhang of the frame.

The chassis contains a hinged cab, under which there is an engine, a frame with front and rear overhangs, made of side members and cross members with an extension to the side of the cabin, mounted on the left side member of the frame frame; IR batteries with two receivers and three receivers integrated into a unit, fuel tank mounted on the right side member; silencer with exhaust pipe mounted on the right

Car chassis vertically on a strut with strut, spark arrester installed between

silencer and exhaust pipe, a spare wheel located under the side member in the rear of the frame, plastic wings placed above the wheels of the middle and rear axles (certificate No. 25309 MPK7 V62D 61/10).

A disadvantage of the known technical solution is that the optimum load on the vehicle axles is not ensured when special superstructures with specified technical parameters are installed on the chassis.

The task was to provide optimal load on the axis of the car when installing special superstructures on the chassis.

The problem is solved due to the fact that in a car chassis made with a 6x4 wheel arrangement containing a hinged cab, under which the engine is located, a frame with front and rear overhangs made of side members and cross members with expansion towards the cabin, mounted on the left side member of the frame a battery box with two receivers located under it and three receivers combined in a block, a fuel tank mounted on the right side member, a muffler, an exhaust pipe, a spare wheel located under the side member in the rear Asti frame chassis configured to increased distance between the axes of front and middle axles, with the following geometrical parameters: A / (B + C) 1.57; C / (B + C) 0.27, where: A is the overall length of the chassis; B - the distance between the axles of the front and middle axles;

2 In - the distance between the axles of the middle and rear axles;

C - rear overhang of the frame,

At the same time, the frame is equipped with an additional crossbar located between the front and middle axles, the silencer is installed on the left side member in the middle of the frame with the outlet pipe to the left, and metal shields are installed over the wheels of the middle and rear axles.

Analysis of known technical solutions for scientific, technical and patent documentation showed that the set of essential features of the proposed solution was not previously known, therefore, it meets the condition of “novelty.

The claimed technical solution is illustrated by drawings: FIG. 1 - car chassis, side view; FIG. 2 - the same, top view; FIG. 3 - the same front view; figure 4 is the same, rear view; FIG. 5 - drawing to the abstract.

An automobile chassis made with a 6x4 wheel arrangement comprises a cab 1, a load-carrying frame 2 formed by side members and cross members. Frame 2 is made with the extension towards the cab.

Three axles are installed on the chassis: front axle 3, middle axle 4 and rear axle 5, while axles 4 and 5 are leading. Bridges 4 and 5 have a central final drive, wheel gears, a cross-axle differential lock mechanism.

3 The chassis is made with an increased distance between the axles of the front

bridge 3 and the middle bridge 4 with the following geometric parameters: A / (B + C) 1.57; C / (B + C) 0.27, where:

A - overall length of the chassis 8680 mm;

B - the distance between the axles of the front and middle axles is 4100 mm;

B - the distance between the axles of the middle and rear axles is 1440 mm;

C - rear overhang of the frame 1520 mm.

Cabin 1 is located above the engine and is configured to tilt forward to service the engine. An aerodynamic visor is installed on the roof of the cab. In the front part of the frame 2, a power unit consisting of an engine, a clutch with a hydraulic booster and a ten-speed gearbox is installed on three supports.

The engine air supply system consists of an air intake 6, nozzles and pipes connecting the air intake 6 and the air purifier 7 to the intake manifolds. The air purifier 7 is attached to the engine, and the air intake 6 is fixed to the rear of the cab 1 with clamps.

The muffler 8 is installed in the middle of the frame 2 under the left side member with the outlet pipe 9 to the left.

In the middle part of the frame 2, the fuel tank 10 is installed on the right, and the battery box 11 is installed on the left. The receivers 12 are combined into blocks and are located: two under the box 11 batteries, and three on the frame 2, on the left.

4

Between the axes of the front axle 3 and the middle axle 4 an additional cross member 13 is installed, increasing the rigidity of the frame 2.

In the rear part of the frame 2, under the side members, a spare wheel 14 is mounted horizontally along the axis of the car. In addition, in the rear of the frame 2 there is a safety beam 15 with rear lights installed therein. The safety beam 15 is made of a profile and fixed to the frame 2 rigidly, metal shields 16 are installed above the wheels of the bridges 4 and 5.

The claimed technical solution provides optimal load on the axis of the car when installing special superstructures on the chassis.

The claimed technical solution meets the requirement of industrial applicability and is possible for implementation on standard technological equipment using modern technologies.
