Description

Technical Field

[0001] The utility model belongs to the technical field related to vehicle auxiliary components, and in particular relates to a mechanical connector for a tracked vehicle. Background Art

[0002] The traveling transmission principle of the crawler vehicle mainly depends on the structural design of the crawler track, which enables the crawler vehicle to travel stably on various terrains. Its traveling structure includes driving wheels, guide wheels, follower wheels, supporting wheels and crawler tracks. The engine provides power to the driving wheels, and the driving wheels drive the vehicle forward or backward through the movement of the crawler tracks, which makes the vehicle body move similarly to the way a caterpillar moves, with a large turning angle, which is different from the flexible rotation structure of the four-wheeled vehicle in the prior art. This makes it necessary to have higher requirements for synchronization and coordination when connecting two crawler vehicles. However, the existing trailer connection structure is mostly relatively simple, and the operation requirements of the front and rear vehicles are generally met through universal joints.

[0003] However, when the universal joint structure commonly available on the market is used to connect two tracked vehicles, the universal joint has a short up and down swinging range, which limits the travel of the front and rear tracked vehicles and is inconvenient to use. Utility Model Content

[0029] Example 1:

[0030] Reference Figure 1 and Figure 2As shown, this embodiment provides a mechanical connector for a tracked vehicle, comprising two sets of V-shaped base frames 101 and a middle connecting member 102. The outer ends of the two sets of V-shaped base frames 101 are respectively hinged to the two connected tracked vehicles through movable members 103, so that the two tracked vehicles are connected end to end.

[0031] In the above embodiment, the movable member 103 enables the ends of the two sets of V-shaped base frames 101 to be hinged on the outer shell of the crawler vehicle, providing a swing space. At the same time, the V-shaped structure also effectively limits the safe swing space.

[0032] The middle connecting part 102 includes a No. 1 hinge 104, a No. 1 bolt 105, an inner rotating shaft 106 and an outer shaft 107. The No. 1 hinge 104 is arranged at the internal connection end of the V-shaped base 101 on the right side. One end of the inner rotating shaft 106 is inserted into the No. 1 hinge 104 in a horizontal swinging manner through the No. 1 bolt 105. The other end of the inner rotating shaft 106 is inserted into one end of the outer shaft 107 in a 360-degree rotation manner. The other end of the outer shaft 107 is arranged at the internal connection end of the V-shaped base 101 on the left side.

[0033] In the above embodiment, the two groups of V-shaped base frames 101 are connected by a middle connecting member 102. Since the inner rotating shaft 106 of the middle connecting member 102 is hinged to the No. 1 hinge member 104 through the No. 1 bolt 105, the two groups of V-shaped base frames 101 can swing up and down with the middle connecting member 102 as the fulcrum; since the inner rotating shaft 106 of the middle connecting member 102 is rotatably inserted in the outer shaft 107, the two groups of V-shaped base frames 101 can rotate to different angles with the middle connecting member 102 as the fulcrum, and the two ends of the two groups of V-shaped base frames 101 are respectively hinged to the outer shell of the tracked vehicle through movable parts 103. While ensuring that the turning angles of the front and rear tracked vehicles are not affected, it can be applied to the situation where the left and right groups of tracks have different driving speeds during the turning process of the existing tracked vehicle.

[0034] Example 2:

[0035] In combination with the above embodiments, refer to Figure 1 and Figure 2 As shown, this embodiment provides a mechanical connector for a tracked vehicle, comprising two sets of V-shaped base frames 101 and a middle connecting member 102.

[0039] like Figure 3 and Figure 4 As shown, by setting the movable part 103 and the middle connecting part 102, the different turning angles of the front and rear tracked vehicles, the uneven road surface, and the different driving heights of the left and right tracks are simultaneously satisfied. The overall structure is simple and reasonable. The movable part 103 and the middle connecting part 102 are set separately, the swing and rotation angles are more flexible, and the collision of vehicles can be effectively avoided. In actual use, the connector is also suitable for assembling and connecting two or more tracked vehicles.

[0040] Moreover, if Figures 5 to 7 As shown, when at least two tracked vehicles are assembled together using the above connector, it is suitable for a variety of terrains, including but not limited to uphill, downhill or wavy terrains, and the assembly connection is more stable.
