Embodiment

With reference to specific embodiment, the invention will be further described, the illustrative examples and explanation invented herein For explaining the present invention, but it is not as a limitation of the invention.

As shown in Figure 1 to Figure 3, a kind of endless-track vehicle bogie wheel torque arm damping, including chassis 1, bogie wheel 2nd, locking nut 3, wheel shaft 4, axle sleeve 5, support arm 6, rotating shaft 7, shim liner 8, outer end lock-screw 9, rocking arm 10, lock screw 11st, sliding block 12, connecting rod 13, gripping block 14, clamping screw group 15, torsion bar fixing clip 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, and the wherein big hexagonal column cap of rotating shaft 7 is towards underbody The outside of disk 1, support arm 6 are installed on the big hexagonal column cap of rotating shaft 7 by hexagon ring thereon, and adjust support arm 6 with The angle of horizontal plane, support arm 6 and rotating shaft 7 are tightly locked together by shim liner 8 and outer end lock-screw 9, prevent from disengaging；Wheel Axle 4 is installed on the cylindrical hole of support arm 6, and axle sleeve 5 is set with the wheel shaft 4, and the rolling of bogie wheel 2 dress on the wheel shaft 4, and passes through locking Nut 3 coordinates the screw thread spinning locking of the outer end of wheel shaft 4, prevents bogie wheel 2 from coming off；Rocking arm 10 is installed on rotating shaft by its hexagon ring On 7 small hexagonal column cap, and with good position is adjusted, the plane-parallel with chassis 1 of the two-arm of rocking arm 10 is kept, and passed through Inner lock-screw 18 locks rocking arm 10, prevents from disengaging, and two sliding blocks 12 are sliding in the two-arm of rocking arm 10 respectively, require simultaneously The small pull head of the stretching of two sliding blocks 12 is in the horizontal plane towards on the contrary, and the middle vertical plane of position on rocking arm 10 both guarantee （Pass through the central axis of its own hexagon ring and perpendicular to the face of car body horizontal plane）Symmetrically, while in two sliding blocks 12 Upper respective one lock screw 11 of spinning, on the small pull head for the stretching that connecting rod 13 is hinged on to sliding block 12 by one section of column cap, The small pull head of gripping block 14 is hinged on the other end column cap of connecting rod 13；Torsion bar fixing clip 16 passes through screw thread spinning on its small column cap In the positioning hole of chassis 1, torsion bar 17 is installed in the circular hole of torsion bar fixing clip 16, and passes through stove bolt and primary nut group Pinned into clamping screw group 15, two gripping blocks 14 are embraced by its cylindrical hole and are clipped on two relevant position of torsion bar 17, then Adjustment position, makes that the external part of the articulated linkage 13 of two gripping blocks 14 is parallel to each other and direction is on the contrary, simultaneously in two connecting rods 13 Then mandrel line forms clamping screw group 15 by stove bolt and primary nut and tightly locks two gripping blocks 14 perpendicular to horizontal plane Tightly, it is firmly embraced and clamp torsion bar 17.

The present invention operation principle be：Load is passed to rotating shaft 7 by bogie wheel 2 by wheel shaft 4 and support arm 6, is changed into turning Torque load is passed to rocking arm 10 by the torque load of axle 7, rotating shaft 7 by hexagonal column cap, and rocking arm 10 is again by both ends sliding block 12 are changed into torque load to pressure, the pulling force that itself is subject to by two connecting rods 13 at pulling force at the one of two connecting rods 13, one Or pressure is changed into the moment of torsion of torsion bar 17 by gripping block 14, torsion bar 17 is elastic torsion material, reaches flat by internal stress Horizontal stroke, torque load is balanced, and because torsion bar 17 is only acted on by moment of torsion, on the vertical plane stress balance, so torsion bar geometrical clamp The stress very little of block 16, to the active force of chassis 1 also very little, the life and reliability used is greatly increased, while torsion bar 17 is more Change also extremely convenient and simple, widened use condition significantly.
