CHASSIS CAR

The invention relates to a car chassis designed for installing various add-ons on them, in particular, a unit for repairing wells.

A car chassis for a mobile pumping unit is known, having a three-axle chassis with a frame made with an extended rear overhang, mounted on the right frame side member, on a rack, an exhaust pipe with a spark arrester pointing upward, a spare wheel mounted vertically behind the cab, fuel tanks located in the middle parts of the frame on both sides (see application N 2000103772/20, IPC 6 F 04 B 23/00).

The closest set of essential features to the claimed technical solution is an automobile chassis made with a wheel arrangement of 6 x 4 with the following geometric parameters:

B / A - 0.66 - 0.70; K / A - 0.66 - 0.70; S / A-B - 0.41 - 0.50;

E / B - 0.41 - 0.50, where:

A is the overall length of the automobile chassis;

B - mounting length of the frame behind the car;

B is the distance from the rear end of the frame to the axis of the intermediate bridge;

K is the distance between the axles of the front and rear axles;

C - front overhang of the frame;

E - rear overhang of the frame,

equipped with a front-mounted hinged cab, under which the engine is located, a frame with front and rear overhangs, five hundred (options1)

IPC 6 V 62 D 61/10

a gear transmission (see ev-in the Russian Federation N 2790, Code of Criminal Procedure 6 V 62 D 21/00, 61/10).

A disadvantage of the known chassis is that its geometrical parameters do not allow placing the unit for well repair on it, as well as insufficient rigidity of the frame and safety during operation.

The problem is solved due to the fact that in an automobile chassis made with a wheel arrangement of 6 x 4 with certain geometric parameters, equipped with a hinged cab under which the engine is located, a frame with front and rear overhangs, the chassis is made with the following geometric parameters:

B / A - 0.74, C / B - 3.39, C / A-B - 0.54. E / B + E - 0.62 where:

A is the overall length of the automobile chassis;

B - mounting length of the frame behind the cab;

B is the distance between the axles of the middle and rear axles;

K is the distance between the axles of the front and middle axles;

C - front overhang of the frame;

E - rear overhang of the frame,

the frame in the front part is made with expansion towards the cab and at the beginning of the expansion is equipped with an additional cross-beam rigidly fixed on it, made arcuate and having a cross-section in the form of a shape, and in the middle part of the frame under the right side member there is a spare wheel located horizontally behind the cab an exhaust pipe directed upward is installed on the right side member of the frame, made curved and significantly protruding above the level of the cab roof; the cream of this chassis can also be equipped with a selection box generality, mounted on removable brackets fixed to the frame for further cross-bar.

s

The analysis of the prior art, including a search by patent and scientific and technical sources of information, made it possible to establish that an analogue characterized by features identical to all the essential features of the claimed technical solution was not found. The definition from the list of identified analogues of the prototype, as the closest in the set of essential features of the analogue, allowed us to establish the set of essential distinguishing features in relation to the technical result in the claimed technical solution, set forth in the claims. Therefore, the claimed technical solution meets the condition of novelty.

The proposed technical solution is illustrated by drawings:

Fig, G drawing to the abstract.

The automobile chassis is made with a 6x4 wheel arrangement. The chassis contains a frame 1 formed by spars of variable cross section and cross members, a cabin that is double and is located above the engine. For ease of engine maintenance, the cab leans forward. Three axles are installed on the chassis: front axle 2, middle axle 3 and rear axle 4, while axle 3 and axle 4 are leading. Bridges are equipped with a cross-axle differential locking mechanism.

The chassis is made with the following geometric parameters:

B - mounting length of the frame behind the cabin 7014 mm;

In - the distance between the axles of the middle and rear axles 1320 mm -

K - the distance between the axles of the front and middle axles is -4470 mm;

C - front overhang of the frame - 1320 mm;

E - rear overhang of the frame - 2190 mm.

The frame 1 is made with expansion towards the cab, at the beginning of the expansion of the frame an additional cross member 5 is installed, which increases the rigidity of the frame 1. The additional cross member 5 is made curved to Jlj in cross section. The additional cross member 5 is rigidly attached to the brackets, which in turn are bolted rigidly to the side members of the frame 1, while the brackets are installed in the place of expansion of the frame 1, their side adjacent to the surface of the side member of the frame, is made at an angle corresponding to the angle frame extensions 1.

In front of the frame 1, a buffer 6 is fixed, having cutouts in which the low and high beam headlights and turning lights are placed.

In front of the frame on four supports is installed a power unit 7, consisting of an engine, a clutch with a pneumatic booster and a five-speed manual gearbox.

Cardan drive 8 consists of three cardan shafts: two shafts connected to each other through a cross and located between the power unit 7 and the middle axle 3 and the rear axle drive shaft 4.

Behind the cab, an air intake 9 and an air cleaner 10 are installed. The air intake 9 is mounted on the cab with clamps. An exhaust pipe And with a spark arrester is installed on the right side member of frame 1. The exhaust is carried out upwards. To ensure installation on the chassis of the unit for well repair and

- 4 to ensure the safety of its operation, the exhaust pipe 11 is made curved and protruding above the roof level of the cabin by 690 mm, and its lower part is placed in a protective casing.

The chassis is equipped with working, parking, spare and auxiliary brake systems having common elements, but working independently of one another.

On the right side member of the frame 1, a box 12 with batteries is fixed to the cab. For the accumulation of compressed air and power supply devices pneumatic brake systems and other consumers with compressed air are receivers connected in two blocks. One block 13, consisting of three receivers, is fixed to the cab on the left side member, and the other block 14, consisting of two receivers, is fixed under the box 12.

In the middle part of the frame 1, a fuel tank 15 with a capacity of 500 l is installed on the left side member, and a spare wheel 16 is mounted horizontally under the right side member on the holder.

A towing eye 17 is fixed on the rear cross member of the frame 1.

The chassis can be equipped with an IS power take-off, which is designed to mount a two-stage power take-off on its upper hatch. The power take-off box is mounted on removable brackets, which are mounted on the frame 1 for an additional cross-member 5. A cardan drive with a power take-off consists of three cardan shafts: a shaft between the power unit 7 and the power take-off 18, the drive shaft of the middle bridge 3 and the drive shaft rear axle 4.

The inventive automotive chassis provides compact placement of the unit for repairing wells and the safety of its operation while the chassis frame has sufficient rigidity.

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