The flexible anti-torsion trailer frame has the advantages of scientific design, strong torque resolving capability, difficult cracking of the joint and long service life.

Description

Flexible anti-torsion trailer frame

Technical Field

The utility model relates to a special vehicle frame, in particular to a flexible anti-torsion trailer frame.

Background

In the traditional semitrailer and other special vehicles, longitudinal beams and cross beams on the frame are all in welded structures, and in the transportation and operation processes, due to reasons such as road jolt, the torque borne by the frame is easily improved, so that the welding seams between the longitudinal beams and the cross beams are cracked and welded, and the service life of the frame is influenced.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides a flexible anti-torsion trailer frame which is scientific in design, strong in torque resolving capability, not easy to crack at a joint and long in service life.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a flexible antitorque trailer frame, includes the bottom plate, sets up two longerons and many crossbeams of bottom plate bottom, every the crossbeam all includes interlude and two end sections, two the end section one-to-one is fixed two on the longeron, the interlude both ends and two the end section adopts non-rigid fixed mode to be connected, makes the interlude with reserve certain activity between the end section.

Based on the above, the end head section and the longitudinal beam are welded and fixed or integrally formed.

Based on the above, the end section is provided with the transverse slot, two ends of the middle section are inserted into the transverse slot, and a movable gap is reserved between the end part of the middle section and the bottom of the transverse slot in a natural state.

Based on the above, the side surface of the end part of the middle section is connected with the side surface of the end head section through a bolt mechanism, and the screw hole at the end part of the middle section and/or the screw hole on the end head section are transverse long holes.

Based on the above, the bolt mechanism comprises two bolts, one bolt above the other bolt below the other bolt.

Compared with the prior art, the split type frame has substantive characteristics and progress, and particularly, the cross beam is arranged into a split type structure, the end head section is fixedly connected with the longitudinal beam, the middle section and the end head section are connected in a non-rigid fixed mode, a certain amount of activity is reserved, so that when the torque borne by the frame is increased, the middle section can be dissolved through the activity of the middle section, the conditions of fracture and welding are avoided, and the split type frame has the advantages of scientific design, strong capacity of dissolving the torque, difficulty in cracking of the connection part and long service life.

Further, the end section with the longeron can be the welding also can be integrated into one piece, the interlude with both can adopt slot structure grafting also can bolted connection between the end section, when adopting slot structure, clearance has guaranteed the activity of interlude, when adopting bolted connection, horizontal slot hole has guaranteed the activity of interlude, bolt mechanism adopts two bolts one on the other, can avoid the slope takes place at the interlude both ends.

Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments.

Example 1

As shown in fig. 1 and 2, the flexible anti-torsion trailer frame comprises a bottom plate 1, two longitudinal beams 2 arranged at the bottom of the bottom plate 1, and a plurality of cross beams 3, wherein each cross beam 3 comprises a middle section 4 and two end sections 5, in this embodiment, the two end sections 5 are welded on the two longitudinal beams 2 in a one-to-one correspondence manner, and in other embodiments, the end sections 5 and the longitudinal beams 2 may also be of an integrally formed structure.

The end head section 5 is provided with a transverse slot 6, two ends of the middle section 4 are inserted into the transverse slot 6, and in a natural state, a movable gap 7 is reserved between the end part of the middle section 4 and the bottom of the transverse slot 6, so that a certain amount of movement is reserved between the middle section 4 and the end head section 5.

The working principle is as follows:

crossbeam 3 is set up to split type structure, use end section 5 with 2 fixed connection of longeron, interlude 4 and end section 5 adopt slot structure butt joint to reserve certain activity, when the trailer traveles on the road of jolting like this, the big moment of torsion that the frame received can pass through the mobilization of interlude 4 is solved, thereby avoids the condition of fracture, welding.

Example 2

As shown in fig. 3 and 4, the present embodiment is different from embodiment 1 in that: 4 tip side of interlude with 5 sides of end head section pass through bolt mechanism and connect, bolt mechanism includes two bolts 8 one on the other to avoid 4 inclinations in interlude, the screw of 4 tip in interlude and/or screw on the end head section 5 is horizontal slot hole, so that the formula makes interlude 4 with certain activity is left between the end head section 5. When the bicycle frame is used, the relative movement of the bolt 8 and the transverse long hole can relieve the torque applied to the bicycle frame.

Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
