(5) INDEPENDENT TORSION SUSPENSION OF TRACKED MACHINE

one

The invention relates to the field of transport engineering, primarily to tracked vehicles. .

The independent torsion suspension is known, containing arms that support the trunnions of the wheels, the torus (ions pivotally mounted in one row on the vehicle frame. Above the arms of the axles of the wheels a rocker arm with elastic elements interacting with the supports Cn is mounted.

The disadvantages of such a suspension are low power consumption and rigidity due to insufficient torsion length.

Also known is an independent torsional suspension of a tracked vehicle, containing frames located in a transverse beam, installed in two rows, and one-arm balancers connected to them, supporting the supporting rollers of the engine 2.

A vehicle with such a suspension has several advantages, however, it has limited maneuverability due to reduced ground clearance, limited by the crossbar.

The aim of the invention is to increase the permeability by increasing the road clearance.

This is achieved by the fact that the axes of the torsions are located at the vertices of an equilateral trapezium facing downward with a small base, and the rollers of one side are connected by the indicated balancers with torsions located along the diagonal of the trapezium.

70 links of the frame 2 of the caterpillar machine, bushings 3 and j are pressed in which the torsion bar S is pressed by the size of its course, lever 6 with the supporting roller 7 In each bar 1, four torsions are installed. Torsion bar 5 is installed on the one hand in the arms of the arm 6, and on the other in the slots of the lid 8 of the beam 1 and is secured from axial shears with a nut 9 and a bolt 10 fixed by the washer 11 against turning. The cover 8 is mounted on the sleeves 3 and screwed to the bar 1 bolts 12 through the gasket 13. These bolts are locking the TC with spring washers. The surfaces of the axis of the lever 6 work in oil and are sealed on one side by the pack / arm 15 installed in the lid 8 and on the other side by the ring 16. For axial adjustment and installation along the tracks of the rollers 7 with the lever 6, gaskets 17 are provided. These rollers, to obtain the desired elastic characteristics of the suspension and to reduce the blows to the tractor frame at the end of the stroke of each roller on the frame 2, are provided with a stop 18, for example, of a spring telescopic type. When the torsions are located on the vertices of the isoscale trapezium facing the small base down, when the rollers of one side are connected to the torsion weights located diagonally, with the same characteristic of the torsion elasticity, the ground clearance is increased and, as a result, the patency of the vehicle is improved. Suspension works as follows. . When an obstacle is hit by the roller 7, the corresponding torsion is twisted through the lever 6. The magnitude of the spin stroke of a torsion located in the upper row of the trapezium is slightly less than the magnitude of the spin motion of the torsion located in the lower row. Due to the difference in the spin characteristics of the torsions on one side of the machine, an increased smoothness of the suspension and better conditions for its operation are achieved, since by applying various characteristics, the optimum total performance of the entire suspension is achieved. By placing the torsions diagonally at the corners of the trapezoid, with the same characteristic of the elasticity of the suspension, the vehicle’s increased permeability by increasing the ground clearance. Claims of the invention Independent torsional suspension of a tracked vehicle, comprising torsions frames arranged in a cross-beam, installed in two rows, and one-arm balancers connected to them, carrying the support rollers of the drive, characterized in that, in order to increase maneuverability by increasing ground clearance, the axle torsions are located at the vertices of an equilateral trapezium with the small base facing downwards, and the rollers of one side are connected by the specified balancers with torsions located along the diagonal of the trapezium.
