Detailed description of the invention

Below in conjunction with specific embodiment, the invention will be further described, is used for explaining the present invention in this illustrative examples of inventing and explanation, but not as a limitation of the invention.

As shown in Figure 1 to Figure 3, a kind of continuously tracked vehicle bearing wheed torsion bar damping, comprise chassis 1, bearing wheed 2, jam nut 3, wheel shaft 4, axle sleeve 5, hold-down arm 6, rotating shaft 7, shim liner 8, outer end lock screw 9, rocking arm 10, lock screw 11, slide block 12, connecting rod 13, clamp 14, lock bolt group 15, torsion bar fixes fixture block 16, torsion bar 17, inner lock screw 18, it is characterized in that: rotating shaft 7 is installed in the corresponding circular hole of the both sides of chassis 1, the large hexagonal column cap of its shaft 7 is towards the outside of chassis 1, hold-down arm 6 is installed on the large hexagonal column cap of rotating shaft 7 by the hexagon ring on it, and adjust the angle of hold-down arm 6 and horizontal surface, by shim liner 8 and outer end lock screw 9, hold-down arm 6 and rotating shaft 7 are tightly locked together, prevent from throwing off, wheel shaft 4 is installed on the cylindrical hole of hold-down arm 6, and axle sleeve 5 is set with on the wheel shaft 4, and bearing wheed 2 rolls dress on the wheel shaft 4, and coordinates the screw thread spinning of wheel shaft 4 outer end to lock by jam nut 3, prevents bearing wheed 2 from coming off, rocking arm 10 is installed on the little hexagonal column cap of rotating shaft 7 by its hexagon ring, and with adjusting position, keep the two-arm of rocking arm 10 with the plane-parallel of chassis 1, and lock rocking arm 10 by inner lock screw 18, prevent from throwing off, two slide blocks 12 respectively cunning are contained in the two-arm of rocking arm 10, require that the little pull head stretched out of two slide blocks 12 is towards the opposite in the horizontal plane simultaneously, and position both ensureing about rocking arm 10 middle vertical plane (namely pass through himself hexagon ring central axis and perpendicular to the face of car body horizontal surface) symmetrically, respective spinning lock screw 11 on two slide blocks 12 simultaneously, connecting rod 13 is hinged on the little pull head stretched out of slide block 12 by the column cap of a section, the little pull head of hinged clamp 14 on the other end column cap of connecting rod 13, torsion bar fixes fixture block 16 by screw thread spinning on its little column cap in the knock hole of chassis 1, torsion bar 17 is installed on torsion bar and fixes in the circular hole of fixture block 16, and pinned by stove bolt and primary nut composition lock bolt group 15, two clamps 14 are embraced by its cylindrical hole and are clipped on the relevant position, two of torsion bar 17, then position is adjusted, the external part of the articulated linkage 13 of two clamps 14 is parallel to each other and towards the opposite, and two connecting rod 13 central axis upright are in horizontal surface, then by stove bolt and primary nut composition lock bolt group 15, two clamps 14 are tightly locked, make it firmly embrace and clamp torsion bar 17.

Principle of work of the present invention is: load is passed to rotating shaft 7 by wheel shaft 4 and hold-down arm 6 by bearing wheed 2, become the torque load of rotating shaft 7, torque load is passed to rocking arm 10 by hexagonal column cap by rotating shaft 7, torque load to be changed into the place's pulling force to two connecting rods 13 by two ends slide block 12 by rocking arm 10 again, one place's pressure, the pulling force that self is subject to by two connecting rods 13 or pressure change the moment of torsion of torsion bar 17 into by clamp 14, torsion bar 17 is elastic torsion material, reach flat horizontal by internal stress, balance torque load, again because torsion bar 17 is by torsional interaction, stress balance on the vertical plane, so torsion bar to fix fixture block 16 stressed very little, also very little to chassis 1 application force, greatly increase the life and reliability of use, the replacing of torsion bar 17 is also extremely convenient and simple simultaneously, greatly widen usage condition.
