Description

The utility model relates to the field of engineering, namely to vehicles intended for the transportation of large-sized cargo.

It is known the chassis of a heavy-duty car made with a 6x4 wheel arrangement, containing a hinged cab, under which there is an engine, a frame of spars and cross members, made with expansion towards the cab and with a reduced width in the rear, an air intake, an air cleaner, a silencer mounted to the left under spar outlet pipe, battery box, five receivers combined in blocks: one of the two receivers is located under the battery box, and the other of the three receivers is located on frame on the right side (RF patent No. 21574, IPC 6 V 62 D 61/10, BIMP. No. 3, 2002).

The closest analogue in terms of the set of essential features to the claimed technical solution is the chassis of an off-road truck, made with a 6x6 wheel arrangement, containing a hinged cab, under which there is an engine, a frame made of side members and cross members, made with expansion towards the cab and with a reduced width of the rear part, fixed with a bracket and a rack to the rear wall of the cab, a multi-cyclone air purifier with an intake pipe attached to it, box

batteries, five receivers, two of which are combined into a block and placed under the battery box, and three - are combined into a block and placed on the frame on the right side, a silencer mounted to the right under the frame in front of the middle bridge, an exhaust pipe led above the middle universal joint shaft to the left to the gas bypass box, after which the release is carried out either up or to the left, the fuel tank, cross-axle differentials, a safety beam mounted in the rear of the frame (RF patent No. 37974, MPK ⁷ B 62 D 61/10, BIMP No. 14, 2004).

Problem to be solved: layout improvement of the chassis, which allows for the transportation of bulky goods.

The problem is solved due to the fact that in a truck tractor for transportation of bulky goods containing a chassis made with a 6 × 6 wheel arrangement, a hinged cab under which the engine is located, a frame with front and rear overhangs, a cardan gear, final drive, cross-axle differentials, brake chambers located in the upper part of the bridges inside the frame, front and rear suspensions, a transfer box installed between the gearbox and the middle axle, an air cleaner, an air intake, a silencer installed d the middle bridge with the exhaust pipe pointing to the left, the battery box, five receivers two of which are combined in a block and placed under the battery box, and three are combined in a block and placed on the frame on the right side, a fuel tank mounted on the left on the frame, the cabin is made with a berth, on a frame between the middle and

rear axles have a subframe mounted on it with a fifth wheel coupling, capable of turning back and forth, left-right, while the axis of the fifth wheel coupling is shifted relative to the axis of the rear suspension balancer in the direction of the middle bridge, in front of which a mud floor is mounted on the frame and on the right side, on the frame between the battery box and the block of three receivers, a ladder is fixed for lifting onto the mentioned mud floor, in addition, the air purifier is installed on the left on the frame by means of ronshtein.

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 the drawings:

figure 1 - truck tractor for transportation of bulky goods, side view;

figure 2 is the same, a top view;

A truck tractor for transportation of bulky goods, contains a chassis made with a 6x6 wheel arrangement, a cab 1, a frame 2 formed by side members and cross members with front and rear overhangs. Frame 2 is made with expansion towards the cab and a reduced width at the rear. In front of the frame, a towing cross member is installed, to which the headlight panel, spoiler and additional steps are attached.

Cabin 1 is located above the engine and is configured to tilt forward to service the engine. Cabin 1 is made with a berth. The power unit is installed in front of the frame 2 on three legs and a support leg.

The chassis has three driving axles: front axle 3, middle axle 4, rear axle 5.

Bridges 4 and 5 have a central final drive, cross-axle differentials. Brake chambers are located in the upper part of the bridges inside the frame 2.

A transfer box is installed between the gearbox and the middle bridge 4. The cardan drive consists of four cardan shafts: the main shaft between the gearbox and the transfer case 6, the front axle drive shaft 3, the middle axle drive shaft 4, and the rear axle drive shaft 5.

On the left side under the frame 2 in front of the bridge 4 there is a muffler 7 with an exhaust pipe 8 directed to the left.

The engine air supply system consists of an air intake 9, an air cleaner 10 nozzles and pipes connecting the air intake, an air cleaner and engine cylinders. The air cleaner 10 is mounted using the bracket on the left of the frame 2.

In the middle part of the frame 2, a fuel tank 11 with a capacity of 500 liters is installed on the left. To the right of frame 2 is a box of 12 batteries. Receivers 13 are combined in blocks of two and three receivers, which are placed

respectively, on the right under the box 12 batteries and on the right on the frame 2.

A frame 14 is mounted on the frame 2 between the bridge 4 and the bridge 5, providing a loading height equal to 1885 mm for the semi-trailer with the gross vehicle weight. On the subframe 14, a fifth wheel coupling 15 is fixed having the ability to turn back and forth and left-right. The axis of the fifth wheel coupling 15 is offset relative to the axis 16 of the balancing device in the direction of the middle bridge 4 by 400 mm.

To connect the pneumatic and electrical outputs of the chassis and semitrailer, a mud deck 17 is mounted on the frame 2 in front of the bridge 4, and a ladder 18 is mounted on the right side between the battery box 12 and the block of three receivers 13 to climb the mud deck 17.

The inventive truck tractor for transportation of bulky goods has a chassis with an improved layout, allowing for the transportation of bulky goods.

The inventive truck tractor for transportation of bulky goods meets the requirement of industrial applicability and is possible for implementation on standard processing equipment using modern technologies.
