Detailed Description
Referring to fig. 1-4, the utility model provides a buffer type traction rod for a vehicle, which comprises a pull rod barrel 1 with a cavity, a pull rod 2 with one end extending into the cavity of the pull rod barrel 1, and a buffer component arranged between the pull rod 2 and the pull rod barrel 1. The other end of the pull rod barrel 1 is provided with a connecting rod 3, and the connecting rod 3 is hinged with the pull rod barrel 1 by a pin shaft 4. The pull rod 2 is provided with a first joint 5, and the connecting rod 3 is provided with a second joint 6. The two joints are respectively connected with the towed and towed vehicles, wherein the second joint 6 and the pull rod barrel 1 can relatively rotate, so that the two joints can be smoothly connected with the corresponding vehicles even if the parked positions of the towed vehicles deviate.
The buffer assembly comprises an end cover 11 which is in threaded connection with the pull rod barrel 1 and is used for closing the cavity, two support sleeves 12 which are respectively arranged on the inner side of the end cover 11 and the inner end surface of the cavity, two sliding gaskets 13 which are arranged between the two support sleeves 12, a plurality of disc spring groups which are arranged between the two sliding gaskets 13, and a nut 14 which is arranged on the outer side of the sliding gaskets 13 and is in threaded connection with the pull rod 2. The bidirectional buffering can be realized by arranging the nut 14 and the shaft shoulder on the pull rod 2, two sliding gaskets 13 positioned between the nut 14 and the shaft shoulder and a disc spring group positioned between the two gaskets. Each disc spring group comprises at least two disc springs 15 which are arranged side by side, and the adjacent disc spring groups are arranged in series or in parallel. The disc springs are adopted as elastic elements, and the bearing capacity is improved by connecting different numbers of disc springs in parallel, so that the bearing capacity of the elastic elements is more than 10-20 tons for realizing the traction of large-tonnage vehicles; in the concrete implementation, the rigidity can be reduced and the buffer effect can be improved by connecting different numbers of disc springs in series; in general, a series-parallel combined structure is adopted to realize variable rigidity so as to adapt to different working condition requirements.
A sealing ring 16 is provided between the end cap 11 and the pull rod 2 to prevent dust from entering the cavity.
Embodiment one: referring to fig. 1, in this embodiment, a limiting assembly for limiting the rotational degree of freedom of the connecting rod 3 is provided between the draw-bar barrel 1 and the connecting rod 3. The limiting component comprises a pressure spring 7 sleeved on the pull rod barrel 1, and a limiting sleeve 8 sleeved at one end of the pull rod barrel 1 and positioned at the hinge joint of the pull rod barrel 1 and the connecting rod 3 under the acting force of the pressure spring 7.
Specifically, a hinge rod 9 is arranged at the end part of the pull rod barrel 1, a groove 9-1 and a hinge hole at the end part of the limit pin 4 are arranged at the free end of the hinge rod 9, a boss 3-1 positioned in the groove 9-1 is arranged at one end of the hinge rod 9, and a hinge hole for the pin 4 to pass through is arranged on the boss 3-1. The outer diameters of the hinged end of the hinged rod 9 and the hinged end of the connecting rod 3 are equal, and the length of the pin shaft 4 is smaller than the inner diameter of the limit sleeve 8. The connecting rod 3 is provided with a limiting table 3-2 which is used for limiting the limiting sleeve 8 at the hinge joint of the hinge rod 9 and the connecting rod 3 and is annular. When the connecting rod 3 and the pull rod barrel 1 need to rotate relatively, the limiting sleeve 8 is pushed inwards to leave the hinged position (the pressure spring 7 is compressed in the process), and the connecting rod 3 is no longer positioned in the limiting sleeve 8, so that the connecting rod 3 can rotate relatively with the pull rod barrel 1 to realize connection with a vehicle. When two vehicles are connected, the connecting rod 3 is gradually positioned on the same axis with the pull rod barrel 1 in the traction process, and the limiting sleeve 8 automatically moves to the hinge under the acting force of the compression 7 to limit the rotational freedom degree of the connecting rod 3 again.
Embodiment two: referring to fig. 2 and 3, unlike the embodiment, in this embodiment, a limit screw 10 is fixed to a hinge rod 9 to be limited in a limit groove 8-1 of a limit sleeve 8, and the limit groove 8-1 is L-shaped. When the connecting rod 3 and the pull rod barrel 1 need to rotate relatively, the limiting sleeve 8 is pushed inwards to enable the pressure spring 7 to be compressed, the limiting screw 10 slides to the turning part of the pressure spring along the limiting groove 8-1, then the limiting sleeve 8 is rotated to enable the limiting screw 10 to enter the groove on the other side, and at the moment, the connecting rod 3 is not located in the limiting sleeve 8 any more, so that the connecting rod 3 and the pull rod barrel 1 can rotate relatively. When two vehicles are connected and then the connecting rod 3 is gradually positioned on the same axis with the pull rod barrel 1 in the traction process, and the rotation of the connecting rod 3 is required to be limited again, the limiting sleeve 8 is horizontally rotated at first so that the limiting screw 10 is positioned at the turning part of the limiting groove 8-1, and then the limiting sleeve 8 automatically moves to the hinging position under the acting force of the compression 7 to limit the rotation freedom degree of the connecting rod 3 again.
The traction rod can be used as a conventional traction rod and also can be used as a push rod. Taking the first embodiment as an example, when the traction rod is used, the limiting sleeve 8 is pushed inwards to enable the pressure spring 7 to be compressed and simultaneously leave the hinge, at the moment, the connecting rod 3 is no longer positioned in the limiting sleeve 8, and the connecting rod 3 can rotate relative to the hinge rod 9. The two joints connect the two vehicles respectively, and the towing vehicle pulls the towed vehicle through the towing bar. When the push rod is used, the limiting sleeve 8 is pushed inwards firstly so that the pressure spring 7 is compressed and leaves the hinge position, the connecting rod 3 is not positioned in the limiting sleeve 8, and the connecting rod 3 can rotate relative to the hinge rod 9. The two joints are respectively connected with the two vehicles, then the traction vehicles move backwards to enable the connecting rod 3 and the hinging rod 9 to be basically positioned on the same axis, and at the moment, the limiting sleeve 8 moves towards the connecting rod 3 under the action of the pressure spring 7 and limits the connecting rod again. The vehicle located at the rear can push the vehicle ahead by the traction lever.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same; while the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present utility model or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the utility model, it is intended to cover the scope of the utility model as claimed.
