A disadvantage of the known technical solution is its low maneuverability indicators.

The task was set to increase the vehicle's maneuverability by reducing the wheelbase. This indicator is very important for cars designed for utility needs, when you need to perform a U-turn on as small an area as possible.

The problem is solved due to the fact that the low-frame chassis of the delivery vehicle, made with a 4 × 2 wheel arrangement, contains a folding double cab, under which the engine is located, a frame with front and rear overhangs, made of spars of a constant channel section and cross members and equipped with a front and rear underrun safety bars, front and rear suspensions made on leaf springs and having anti-roll bars, an air intake fixed to the rear cab, air a cleaning device connected to it and located above the engine, a battery box mounted on the right side member of the frame behind the cabin, a silencer located on the left under the side member of the frame, the exhaust pipe of which goes to the left side of the chassis, receivers fixed to the side members of the frame, a fuel tank fixed in the front of the frame on the left side member, gearbox, cardan gear, towing device or towing eye, mounted on the rear cross member, the chassis is made with a wheelbase of 3500 mm, contains four ie the receiver, two of which are combined into a block and placed under a box of batteries, and the transmission can be performed with the power take-off and the cabin - sleeper.

According to the second embodiment, in addition, the rear suspension is made on trailing arms with a pneumatic strut.

According to the third embodiment, the chassis is made with a wheelbase of 4200 mm, contains four receivers, two of which are combined into a block and placed under the battery box, while the gearbox can be made with a power take-off, and the cab can sleep.

According to the fourth embodiment, in addition, the rear suspension is made on trailing arms with a pneumatic strut.

In the claimed technical solution by reducing the size of the wheelbase, as well as the use of air suspension, high rates of maneuverability of the automobile chassis are achieved.

An additional technical result for the second and fourth versions is to increase the comfort of the car chassis.
