Abstract
The utility model discloses a kind of New type detachable rotation-prevention propelling rod structure being mainly used in cross-country car, comprising: the first propelling rod, outer tube and the second propelling rod, the first propelling rod is solid construction, and the second propelling rod is hollow steel pipe structure; Be provided with the 3rd screw thread at the inwall of outer tube, be provided with the first screw thread at the outside face of the first propelling rod and outer tube contact jaw, be provided with the second screw thread at the outside face of the second propelling rod and outer tube contact jaw; By rotary sleeve pipe, the first propelling rod and the second propelling rod can be made to move near direction or move away simultaneously; First propelling rod inserts the second propelling rod part and is provided with boss, and the second propelling rod and the first propelling rod contact portion are provided with spacing groove.The beneficial effects of the utility model are: by rotating jacket pipe, the first propelling rod and the second propelling rod are moved laterally, realize the release of the pulling force suffered by propelling rod, thus facilitate propelling rod dismounting.
Description
Technical field
The utility model relates to a kind of split type rotation-prevention propelling rod structure, relates to a kind of New type detachable rotation-prevention propelling rod structure being mainly used in cross-country car in particular.
Background technology
Propelling rod is mainly used in cross-country car independent rear suspension, and its one end is connected with vehicle body, and the other end is connected with suspension, and due to tare, the propelling rod after assembling is all subject to the effect of preloaded in traction, is therefore difficult to carry out disassembling, assembling and replacing to it.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of rational in infrastructure, the New type detachable rotation-prevention propelling rod structure being mainly used in cross-country car of easy disassembly.
This New type detachable rotation-prevention propelling rod structure being mainly used in cross-country car, comprising: the first propelling rod, outer tube and the second propelling rod, the first propelling rod is solid construction, and the second propelling rod is hollow steel pipe structure; Be provided with the 3rd screw thread at the inwall of outer tube, be provided with the first screw thread at the outside face of the first propelling rod and outer tube contact jaw, be provided with the second screw thread at the outside face of the second propelling rod and outer tube contact jaw; By rotary sleeve pipe, the first propelling rod and the second propelling rod can be made to move near direction or move away simultaneously; First propelling rod inserts the second propelling rod part and is provided with boss, and the second propelling rod and the first propelling rod contact portion are provided with spacing groove.
As preferably: be provided with the first tangent plane outside described outer tube, be provided with the second tangent plane outside the second propelling rod.
As preferably: described first propelling rod overall diameter is less than the second propelling rod interior diameter, is free-running fit mutually, is also free-running fit between boss and groove, prevent from outer tube from rotating producing locked.
The beneficial effects of the utility model are: by rotating jacket pipe, the first propelling rod and the second propelling rod are moved laterally, realize the release of the pulling force suffered by propelling rod, thus facilitate propelling rod dismounting.This structure first propelling rod and the second propelling rod only produce large rotation in moving process, avoid causing extrusion damage to lining, and after assembling, the first propelling rod and the second propelling rod can not exist moment of gyration in axial-rotation direction.
Accompanying drawing explanation
Fig. 1 is the utility model mounting structure schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the A-A cutaway view of Fig. 2.
Description of reference numerals: the first propelling rod 1, first nut 2, first tangent plane 3, back axle 4, second tangent plane 5, second propelling rod 6, shock absorber 7, clamp 8, brake disc 9, spring 10, vehicle frame 11, second nut 12, outer tube 13, limiting stopper 14, boss 15, groove 16, first screw thread 17, second screw thread 18, the 3rd screw thread 19.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, improved type and equivalent.
As shown in Figure 1 to Figure 3, the distance rod assembly of the present embodiment is made up of upper first propelling rod 1, outer tube 13 and the second propelling rod 6 three part, and the first propelling rod 1 is solid construction, and the second propelling rod 6 is hollow steel pipe structure.
Be provided with the 3rd screw thread 19 at the inwall of outer tube 13, be provided with the first screw thread 17 at the first propelling rod 1 with the outside face of outer tube 13 contact jaw, be provided with the second screw thread 18 at the second propelling rod 6 with the outside face of outer tube 13 contact jaw.By rotary sleeve pipe 13, the first propelling rod 1 and the second propelling rod 6 can be made to move or move away near direction, Fig. 2 simultaneously.
First propelling rod 1 inserts the second propelling rod 6 part and is provided with boss 15, second propelling rod 6 and the first propelling rod 1 contact portion are provided with groove 16, first propelling rod 1 external diameter and the second propelling rod 6 are free-running fit, it is also free-running fit between boss 15 and groove 16, when ensureing rotary sleeve pipe 13, can not produce locked between first propelling rod 1 and the second propelling rod 6, Fig. 2, Fig. 3.
By boss 15 and groove 16 position-limiting actions between first propelling rod 1 and the second propelling rod 6, during rotary sleeve pipe 13, the second tangent plane 5 is blocked with spanner, realize can not producing large rotation when the second propelling rod 6 and the first propelling rod 1 move, thus extruding can not be caused to propelling rod both sides lining, and after assembling, moment of gyration can not be there is in axial-rotation direction, Fig. 2, Fig. 3.
When tearing propelling rod open, a hand spanner blocks at the first tangent plane 3 place, prevents outer tube 13 from rotating, and then another hand spanner unclamps the first nut 2 and the second nut 12.Then block the second tangent plane 5 with spanner, rotary sleeve pipe 13 makes the first propelling rod 1 and the second propelling rod 6 away, thus the pulling force suffered by propelling rod is discharged.
During installed thrust bar, rotary sleeve pipe 13 makes the first propelling rod 1 and the second propelling rod 6 move near direction, after moving to design attitude, the pulling force suffered by propelling rod is applied, fastening first nut 2 and the second nut 12.
