In the description of the present application, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "disposed" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in this application will be understood to be a specific case for those of ordinary skill in the art.

The GST platform car in this application drags frock, drags the removal to the GST platform car in the mainly used autopilot test field. The current in-process of dragging is specifically used for solving because the trailer emergency brake, the striking of GST platform truck and trailer afterbody under the inertia to and GST platform truck's passive trail of dragging unrestricted, there is great skew problem with the trailer route.

Referring to fig. 1-3, the utility model provides a GST platform truck pulls frock, the main part pulls the structure and includes dead lever 10 and slide bar 20, and dead lever 10 connects at the afterbody of trailer, and slide bar 20 connects the front end at GST platform truck. The fixed rod 10 mainly outputs the towing force of the trailer, and the sliding rod 20 plays a role of passive towing.

When the trailer is normally dragged, the fixed rod 10 and the sliding rod 20 extend to the maximum length, when the speed of the trailer is reduced or the trailer is braked, the sliding rod 20 slides forwards relative to the fixed rod 10 along with the inertia of the GST platform vehicle, so that the length between the fixed rod and the sliding rod is contracted, and when the trailer normally runs forwards again, the sliding rod 20 passively extends and slides and is reset to the maximum extending state.

Dead lever 10 articulates with the trailer, and slide bar 20 articulates with GST platform car, and based on foretell pull the walking process, the transition process of trailer in different travel state, slide bar 20 can stretch out and draw back the removal in dead lever 10, accomplishes normal traction and pulls.

Be provided with the elastic component that can supply 20 tip butts of slide bar in the inside of dead lever 10, can make the flexible buffering of rigidity striking that produces between 20 tip of slide bar and the dead lever 10 with GST platform truck inertia antedisplacement to guarantee to drag the security of process, reduce the influence that rigidity striking caused GST platform truck performance.

In one specific embodiment, the movable end of the sliding rod 20 is inserted into the fixed rod 10, so that the sliding rod 20 and the fixed rod 10 can be kept on the same straight line, and the trailer can be kept dragging the GST platform car straight, and the sliding rod 20 can be moved in the axial direction of the fixed rod 10, i.e. the straight line direction formed by the two.

The elastic assembly is disposed inside the fixing lever 10, and specifically, the fixing lever 10 includes a cavity therein, and the elastic assembly includes a cylindrical elastic member disposed in the cavity. Can make the movable end that slide bar 20 was located in dead lever 10 inner chamber butt when the shrink slides on the column elastic component, turn into the flexible buffering with the rigidity striking, reduce the influence that the rigidity striking caused trailer and GST platform truck.

The sliding fit between the fixed rod 10 and the sliding rod 20 is performed through a bolt and a sliding groove on the sliding rod 20, the sliding groove is specifically a closed groove with a certain length and arranged in the length direction of the sliding rod 20, the movable end of the sliding rod 20 is a closed end, and the sliding groove is a through groove 21 arranged in the radial direction of the sliding rod 20.

Furthermore, a fixing bolt 40 is installed at the end of the fixing rod 10 connected to the sliding rod 20, the fixing bolt 40 is inserted in the sliding slot of the sliding rod 20 in the radial direction of the fixing rod 10, and the fixing bolt 40 is fixed by a fixing nut 50. The sliding rod 20 can be telescopically slid with respect to the fixing rod 10 by the clearance fit between the fixing bolt 40 and the sliding groove. At the same time, the relative movement of the sliding rod 20 and the fixing rod 10 can be prevented from slipping out by fastening the fixing bolt 40 by the fixing nut 50. The fixing bolt 40 and the fixing nut 50 adopt a bolt and a matching nut of standard M12, and are convenient to disassemble.

In a specific use process, based on the sliding of the sliding rod 20 relative to the fixing rod 10, the sliding slot, i.e. the through slot 21 on the sliding rod 20, extends along the axial direction of the sliding rod 20, and the sliding slot is arranged between the movable end and the hanging end on the sliding rod 20. The slide rod 20 can be made to slide in a telescopic manner in a linear direction formed by the fixed rod 10 and the slide rod 20, and the sliding range is limited to the length of the through groove 21. The arrangement mode can set the length of the through groove 21 according to actual working conditions in specific application so as to achieve the purpose of controlling the sliding range of the sliding rod 20.

According to the flexible buffer formed by the cylindrical elastic member, the cylindrical elastic member in the present embodiment includes the compression spring 30 disposed in the inner cavity of the fixing rod 10. The diameter of the compression spring 30 in the embodiment is larger than that of the sliding rod 20, so that the sliding rod 20 is prevented from being inserted into the compression spring 30 during sliding, and the stretching and resetting of the sliding rod 20 are prevented from being influenced.

The compressed spring 30 is used as a damping spring, and can be placed in an inner cavity of the fixing rod 10 through an end opening of the fixing rod 10 connected with the sliding rod 20, then the sliding rod 20 is placed in the fixing rod 10, and the angle is adjusted to ensure that the fixing bolt 40 can penetrate out of the bolt hole 11 in the fixing rod 10 and the through groove 21 of the sliding rod 20. The two ends of the pressure spring 30 are respectively provided with a bearing surface, the bearing surfaces can be attached to the cavity wall at the inner side end of the inner cavity of the fixed rod 10 and the movable end of the sliding rod 20, and the damping function of the dragging tool is given.

In addition to the form of the compression spring 30, the columnar elastic member may be a silica gel column having a diameter larger than that of the slide rod 20, and the effect of converting rigid impact into flexible buffering can also be achieved.

Referring to fig. 4-5, in another embodiment, the hanging ends of the fixed rod 10 and the sliding rod 20 are respectively connected with a hook 60, and the trailer and the GST platform cart are both connected with a hanging assembly 70, and the fixed rod 10 and the sliding rod 20 are connected to the trailer and the GST platform cart by connecting the hook 60 to the hanging assembly 70.

The hook 60 in this embodiment is specifically installed at the hanging end of the fixing rod 10 and the sliding rod 20 in a detachable screw connection manner, the hook 60 includes an annular ring 61 and a connecting rod 62, wherein the annular ring 61 is connected with the hanging component 70, the outer side wall of the connecting rod 62 is provided with a thread, the threaded connecting rod 62 forming the hook 60 is provided with a threaded hole 80, and the hanging end of the fixing rod 10 and the sliding rod 20 is provided with a threaded hole 80.
