Abstract
The utility model belongs to the field of automobile traction tools, and particularly relates to a three-point type vehicle traction rod. The three-point type vehicle traction rod is characterized by comprising a front traction ring, a first buffering damping oil cylinder traction rod, a second buffering damping oil cylinder traction rod, a first back hinging device, a second front hinging device and a second back hinging device, wherein each of the first buffering damping oil cylinder traction rod and the second buffering damping oil cylinder traction rod comprises a piston rod and a cylinder body; the piston rod of the first buffering damping oil cylinder traction rod is connected with the front traction ring; the piston rod of the second buffering damping oil cylinder traction rod is connected with the front traction ring through the second front hinging device; the first rear hinging device and the second rear hinging device are respectively arranged on the cylinder body of each of first buffering damping oil cylinder traction rod and the second buffering damping oil cylinder traction rod. The three-point type vehicle traction rod has the advantages that the traction is safe and reliable, and the application range is wide. The three-point type vehicle traction rod can be widely used for vehicle traction when the road condition is not good.
Description
Technical field
The utility model belongs to vehicle traction field of tool, is specifically related to a kind of bikini vehicle drawing pull bar.
background technology
Vehicle traction pull bar is a kind of conventional vehicle traction instrument, but conventional drafting tool is the two hard draw bars of single hard draw bar or trigonometric expression now, simplex pull rod is no problem in when traction, is pushed away and adjusts buttocks to knock into the back but exist rear car tune or front truck in the time of emergency braking; The two hard draw bars of trigonometric expression are safe and reliable in the time that traction is kept straight on or braked, but while turning in left and right, because car the turn track that moves ahead in front and back cannot be realized coincidence, cause rear car front-wheel laterally to drag, cause the stressed overweight damage wheel of inside tire and tire, turn radius is excessive, and complex road surface is difficult to use.In the extraordinary situation of road conditions, use special tractor truck at present, but bad or while needing to draw there is no special tractor truck in the situation that at road conditions, drafting tool has just become subject matter, particularly just must consider that this drafting tool has been equipped with when now army's long-distance raid manoeuvre.
utility model content
The purpose of this utility model is to solve prior art vehicle traction pull bar to use the defect dangerous, Applicable scope is little, and a kind of safe, applied widely, retractable bikini vehicle drawing pull bar with damping buffering function that uses is provided.
Basis is practical to be newly achieved through the following technical solutions:
It is a kind of bikini vehicle drawing pull bar, it is characterized in that comprising front haulage ring, the first buffer damping oil cylinder draw bar, the second buffer damping oil cylinder draw bar, the first rear splicer, the second front splicer and the second rear splicer, the first buffer damping oil cylinder draw bar, the second buffer damping oil cylinder draw bar includes piston rod and cylinder body, the piston rod of described the first buffer damping oil cylinder draw bar is connected with front haulage ring, the piston rod of described the second buffer damping oil cylinder draw bar is connected with front haulage ring by the second front splicer, the cylinder body of described the first buffer damping oil cylinder draw bar and the second buffer damping oil cylinder draw bar is respectively equipped with the first rear splicer, the second rear splicer.
As a preferred version of the present utility model: piston rod and the eye hitch of the first buffer damping oil cylinder draw bar are fixed together by screw thread.
The first rear splicer of the present utility model is connected with the special hook of pulling that is pulled automotive front with the second rear splicer again.
Principle of the present utility model is as follows:
When automobile normal straight when operation in traction, two buffer damping oil cylinder draw bars are simultaneously stressed, when turning, the buffer damping oil cylinder draw bar in outside is stressed, along with the variation of angle of turn, the piston rod free-extension of the buffer damping oil cylinder draw bar of inner side, can make the freely servo-actuated turning of rear car and front truck, piston rod buffering retraction oil cylinder when emergency braking, can make rear car slow down and stop, reducing impact.
The utlity model has safe and reliable, the applied widely advantage of traction.The utility model can be widely used in the vehicle traction of road conditions when bad.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Shown in accompanying drawing: 1-front haulage ring; The front splicer of 2-second; 3-the first buffer damping oil cylinder draw bar; 4-the second buffer damping oil cylinder draw bar; The rear splicer of 5-first; The rear splicer of 6-second.
Detailed description of the invention
As shown in Figure 1: the piston rod of the first buffer damping oil cylinder draw bar 3 is threaded by one section of double-screw bolt with front haulage ring 1, the piston rod of the second buffer damping oil cylinder draw bar 4 is flexibly connected with front haulage ring 1 by the second front splicer 2, and the cylinder body of described the first buffer damping oil cylinder draw bar 3 and the second buffer damping oil cylinder draw bar 4 is respectively equipped with the first rear splicer 5, the second rear splicer 6.
When the utility model uses, front haulage ring 1 is articulated in the rear dragging hanging device of tractor truck, and the first rear splicer 5, the second rear splicer 6 are connected to and are pulled the pulling on hook of car.When automobile normal straight when operation in traction, two buffer damping oil cylinder draw bars are simultaneously stressed, the buffer damping oil cylinder draw bar that is in outside when turning is stressed, along with the variation of angle of turn, the piston rod free-extension of the buffer damping oil cylinder draw bar of inner side, can make the freely servo-actuated turning of rear car and front truck, piston rod buffering retraction oil cylinder when emergency braking, can make rear car slow down and stop, reducing impact.
