The problem to be solved by the claimed technical solution is to ensure the reliability of the vehicle.

The problem is solved by the fact that the balancing leaf spring suspension of the vehicle, containing leaf springs, fixed by the middle part with the help of ladders to the shoe, and the ends - on the bridge supports, the upper V-shaped reaction rods installed at one end on the bridge, and the other with the help of the bracket - on the frame, lower reaction rods, brackets with balancer axles, travel stops fixed to the lower flanges of the frame side members above the middle and rear axles, an anti-roll bar, consisting of struts and a U-shaped bar, fixed with bent ends through the lower arms with the rear axle , additionally contains shock absorbers, fixed with the lower part to the lower arms, and the upper part through the bracket - to the side walls of the frame side members, an anti-roll bar fixed through the lower arms with the middle axle, while the anti-roll bars are connected to the side wall of the frame, and the lower jet rods are fixed through bosses to the balancer axle bracket.

The set of distinctive features, consisting in the fact that, the balance spring suspension of the vehicle additionally contains shock absorbers, fixed with the lower part to the lower arms, and the upper part through the bracket - to the side walls of the frame side members, an anti-roll bar fixed through the lower arms with the middle axle, in this case, the struts of the anti-roll bars are connected to the side wall of the frame, and the lower reaction rods are fixed through the lugs to the arm of the balancer axle, which makes it possible to ensure the reliability of the structure during operation on a vehicle.

The essence of the utility model is illustrated by the following drawings:

fig. 2 - the same, top view assembled with a frame and bridges (isometric);

fig. 3 - the same, side view (isometric);

fig. 4 - fastening of the arm of the axis of the balancer and the shoe, section B-B of Fig. 1 (in isometric view).

The balance leaf spring suspension of the vehicle contains leaf springs 1, which are fixed in the middle part through pads 2, ladders 3 and nuts 4 with shoes 5, which have silent blocks 6 at the ends, which are most reliable and durable due to the rubber-metal composition. Shoes 5 of the springs 1 are fixed on the brackets 7 of the axle 8 of the balancer. The ends of the springs 1 are mounted on supports 9, fixed with the middle axle 10 and the rear axle 11 on the right and left with the lower levers 12 using bolts 13. The middle axle 10 and the rear axle 11 are connected to the bracket 7 by means of the lower reaction rods 14 through bolts 15 and nuts 16. The lower reaction rods 14 are fixed with the balance bar axis 8 through the bosses of the bracket 7. This fastening through the bosses eliminates the use of additional parts, in addition, it frees up space in the front of the bracket between the bosses. The balance spring suspension also contains the upper V-shaped rocket rods 17, mounted at one end on the middle axle 10 and the rear axle 11, and at the other end using the bracket 18 to the side walls of the frame side members 19 using bolts 20. In this case, in the middle part of the middle axle 10 and rear axle 11, upper levers 21 are fixed from above with bolts 22. Anti-roll bars are installed to the front part of the middle axle 10 and the rear part of the rear axle 11, consisting of struts 23 and U-shaped rods 24, fixed with bent ends through the lower levers 12 with the middle axle 10 and the rear axle 11 using bolts 25 and nuts 26. In this case, the struts 23 of the anti-roll bars are fixed to the side wall of the frame 19 through the brackets 27 using bolts 28 and nuts 29, which makes it possible to increase the distance between them, thereby holding the suspension falls on a large area of the middle part of the U-shaped bar, that is, the distance between the posts is obtained more than between the frame side members, which allows for better support of the frame on the anti-roll bar during roll, thereby increasing reliability when operating on a vehicle. In addition, the suspension contains shock absorbers 30, which are fixed with the lower part to the lower levers 12 using bolts 31, and the upper part through the bracket 32 to the side walls of the frame side members 19 using bolts 33. The balance suspension also contains travel stops made in the form of rubber buffers 34, fixed to the lower flanges of the frame side members 19 through the support 35 above the middle axle 10 and the rear axle 11 using bolts 36 and nuts 37.

The principle of operation is as follows.

When the vehicle is moving, the suspension of the middle axle 10 and the rear axle 11 dampens vibrations with the help of shock absorbers 30, providing smooth movement due to landing on elastic elements - springs 1, which, together with the lower reaction rods 14 and the upper reaction rods 17, are also guiding elements ... The upper reaction rods 17, in addition to the guiding function, also provide the upper lateral retention of the vehicle from roll when making a turn. The lower lateral restraint of the car from the roll is performed by the anti-roll bar, that is, when turning to the right, the car tends to lean to the left, while it rests on the right side of the frame 19 on the left sides of the bridges 10 and 11 through the left struts 23 and the left sides of the U-shaped rods 24 of the stabilizer lateral stability and is simultaneously held by the right sides of the bridges 10 and 11 through the right sides of the lower reaction rods 14 and the right struts 23. The smooth return of the car to its original position is provided by the shock absorbers 30, preventing the spring 1 from vibrating, providing a smooth landing due to its elastic properties.

The design of this technical solution ensures reliability during its operation on a vehicle.

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