Abstract
The utility model provides a caterpillar torsion bar elastic suspension device, which mainly consists of a solid torsion bar, a hollow torsion bar, a trolley axle bed, a swing arm joining piece, a thrust wheel and so on. The solid torsion bar is telescoped in the hollow torsion bar. The swing arm joining piece is enclosed on the hollowing torsion bar and is connected with the solid torsion bar by means of telescoping. The thrust wheel is fixedly connected with the swing arm joining piece through the shaft of the thrust wheel. The trolley axle bed is fixedly connected with the hollow torsion bar; the torsion bar suspension device is connected with a carriage through the trolley axle bed. When the caterpillar torsion bar elastic suspension device works, the thrust wheel moves upwards and downwards under external force, and the swing arm joining piece rotates clockwise or counterclockwise around the axle center of the torsion bar suspension. The swing arm joining piece rotates to drive one end of the solid torsion bar connected with the swing arm joining piece by means of telescoping to rotate in the same way, thus causing the torsional deflection of the torsion bar, absorbing the vibration energy and damping vibration.
Description
(1) technical field
The utility model belongs to the trac. field, relates to a kind of crawler-tread tractor torsion bar resilient suspension device.
(2) background technology
At present, the crawler-tread tractor that uses in China trac. field adopts resilient suspension more, and its resilient suspension generally adopts coil spring as the buffer shock-absorbing element, and this device mainly comprises: coil spring, internal and external equilibrium arm and two caterpillar wheels.This springing in use runs into when impacting, and realizes buffer shock-absorbing by compression spring.But the coil spring of this device exposes, and in use need often maintenance, and it is bigger to take up room, and ride comfort was relatively poor when work speed was higher.
(3) summary of the invention
The purpose of this utility model is to provide a kind of structure advanced person, reliable operation, use crawler-tread tractor torsion bar resilient suspension device easy to maintenance.
The technical solution of the utility model is: torsion bar resilient suspension device mainly comprises: solid torsion bar 1, hollow torsion bar 2, chassis axle bed 3, combination of arm swing 4, caterpillar wheel 5.It is characterized in that: solid torsion bar 1 is sleeved in the hollow torsion bar 2, chassis axle bed 3 and hollow torsion bar 2 Joints, combination of arm swing 4 one end arm borehole jacks be contained on the hollow torsion bar 2 and with the other end suit of solid torsion bar 1, the axle of combination of arm swing 4 other end arm holes and caterpillar wheel 5 is affixed, combination of arm swing 4 can be made cw or left-hand revolution around the torsion bar suspension axle center, does identical rotation with an end of the solid torsion bar 1 of hollow torsion bar 2 suits together with combination of arm swing 4.Solid torsion bar 1 two ends are fixed with catch.
Symmetry is installed two caterpillar wheels 5 on the affixed supporting wheel shaft in swing arm 4 other end arm holes.
Torsion bar resilient suspension device is the even number symmetric arrangement, and is connected with vehicle frame by the chassis axle bed.
The utility model can reach following beneficial effect:
Crawler-tread tractor in use torsion bar spring utilizes the torsional deflection of torsion bar generation to realize bumper and absorbing shock.Unit mass torsion bar spring institute energy energy stored is bigger than coil spring, so but adopt torsion bar spring saving in material, minimizing quality under same load.It takes up room little than coil spring, arrange more convenient.Simultaneously to make non-spring carry the part quality little for torsion bar spring, helps improving the riding comfort of trac..Because the two ends of torsion bar are connected with hollow torsion bar with adjustable combination of arm swing respectively, thereby can realize vehicle body height adjustment within the specific limits, regulate the crack, ground by the pre-torsional angle of different assemblings.The connection structure of torsion bar spring and combination of arm swing and hollow torsion bar is simple, service-free requirement in maintenance.
(4) description of drawings
Accompanying drawing 1 is the structural front view of the utility model crawler-tread tractor torsion bar resilient suspension device.
Accompanying drawing 2 is the structure birds-eye view of the utility model crawler-tread tractor torsion bar resilient suspension device.
(5) specific embodiment
As shown in Figure 1, 2, crawler-tread tractor torsion bar resilient suspension device mainly comprises: solid torsion bar 1, hollow torsion bar 2, chassis axle bed 3, combination of arm swing 4, caterpillar wheel 5.Solid torsion bar 1 is sleeved in the hollow torsion bar 2, chassis axle bed 3 and hollow torsion bar 2 Joints, combination of arm swing 4 one end arm borehole jacks be contained on the hollow torsion bar 2 and with the other end suit of solid torsion bar 1, the axle of combination of arm swing 4 other end arm holes and caterpillar wheel 5 is affixed, combination of arm swing 4 can be made cw or left-hand revolution around the torsion bar suspension axle center, does identical rotation with an end of the solid torsion bar 1 of hollow torsion bar 2 suits together with combination of arm swing 4.Solid torsion bar 1 two ends are fixed with catch.
During work, when caterpillar wheel 5 runs into external force and moves up or down, coupled combination of arm swing 4 is made cw or left-hand revolution around the torsion bar suspension axle center, the drive that rotatablely moves of combination of arm swing 4 is done identical rotation with an end of the solid torsion bar 1 of its suit, cause the distortion that twists of solid torsion bar 1, thereby realize the purpose of buffer shock-absorbing.
