Description

The utility model relates to vehicle suspensions, in particular to the balancing suspension of vehicle bridges.

Known rear balancing suspension of vehicle bridges, containing rocker rods, brackets with pressed axles of balancers, a transverse coupler fastened in brackets, at the ends of which two-bearing rubber-metal joints of rocket rods connecting brackets with vehicle bridges are fixed through spacers, and connecting the transverse brace to the brackets made by welding (see patent RU No. 43498, IPC7 B62G 5/00, publ. 27.01.2005).

The closest to the claimed technical solution for the purpose, the set of essential features and the technical result achieved is the rear balancer suspension of the vehicle’s bridges, containing longitudinal leaf springs, fixed with the middle part using step-ladders to the shoe, and the ends mounted on bridge supports through elastic elements having rubber-metal hinges of the upper reaction rods mounted at one end on the axle housing of the gearbox of the bridge, and at the other end with the bracket e frames, and lower reaction rods, brackets with pressed axles of balancers, a transverse coupler rigidly fixed in brackets, at the ends of which, through the spacers, two-bearing rubber-metal hinges of lower reaction rods connecting the balancing brackets to the vehicle bridge beams are fixed (see patent RU No. 148755 MPK7 B62G 5/00, published on December 10, 2014).

Known rear axles of the vehicle axles have insufficient suspension travel.

The task was set: to construct the rear suspension of the vehicle axles, providing increased suspension travel.

The problem is solved due to the fact that the rear suspension of the vehicle’s axles, containing longitudinal leaf springs, fixed with the middle part using ladders to the shoe, and the ends mounted on the bridge platforms, upper reaction rods, lower reaction rods, brackets, with pressed axles of balancers, a transverse coupler rigidly fixed in brackets, at the ends of which rubber-metal hinges of the lower reaction rods are fixed, connecting the balance arms to the bridge beams a means mounted on the bridge stabilizer bar, the ends of springs made sliding, and the upper torque arms attached directly to the rocker arm. In the particular case of execution, the transverse coupler of the balancers can be made curved.

The set of distinctive features, namely, that the ends of the leaf springs are sliding, the upper reaction rods are attached directly to the balancer arm, and the transverse coupler of the balancers is curved, which allows to increase the suspension travel by increasing the ride height and eliminating the contact of the transverse coupler with the driveshaft.

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

The claimed technical solution is illustrated by drawings, which depict:

FIG. 1 - rear suspension of vehicle bridges, general view;

FIG. 2 - the same, top view;

FIG. 3 - the same front view.

The rear suspension of the vehicle bridges contains two longitudinal leaf springs 1, upper and lower reaction rods, 2 and 3, respectively, brackets 4 with pressed axles of the balancers 5 and anti-roll bars 6.

Leaf springs 1 are fixed by the middle part with the help of step-ladders 7 to the shoe 8. On the upper part of the beams of the middle and rear axles 9, a platform 10 is attached with pins, on which the ends of the springs 1 rest and slide along.

The upper reaction rods 2 are made at the ends with rubber-metal hinges 11, and are installed at one end on an arm 12, mounted on the crankcase 13 of the bridge gear, and the other end on the arm 4 of the balancers. The upper reaction rods 2 can be made V-shaped.

In the brackets 4 of the balancers, a transverse coupler 15 is rigidly fixed, at the ends of which, through the spacer elements, two-bearing rubber-metal hinges of the lower reaction rods 3 are connected, connecting the brackets 4 of the balancers with the beam of the bridge 9 of the vehicle.

On the rear and middle axles mounted stabilizers 6 lateral stability, consisting of racks and a U-shaped rod.

This layout solution allows you to increase the suspension travel and the angular stiffness of the suspension in the transverse direction and protects the vehicle from tipping over.

The rear axle suspension of the vehicle operates as follows.

When moving road irregularities, vertical movements of the bridges 9 occur, the balancers 5 rotate around the axes and their deformation. Longitudinal reaction rods, lower 2 and upper 3, transmit traction and braking forces from the bridges 9 to the vehicle frame through the arms 4 of the balancer. When spring 1 is deflected, their ends glide along platforms 10. Since the longitudinal movement of the ends of the springs 1 in the suspension elements is not limited within the suspension travel, it is unloaded from the transmission of longitudinal forces and moments acting in the longitudinal plane. For the perception of pushing and reactive forces, the bridge beams 9 are connected by jet rods 2 and 3 with the frame of the vehicle. The anti-roll bars 6 provide minimal lateral roll.

The technical solution meets the requirements of industrial applicability and is possible for implementation on standard processing equipment.
