Description

Technical Field

[0001] The utility model relates to the technical field of tractor saddles, in particular to a coupling adjustment type tractor saddle for a semitrailer. Background Art

[0002] With the rapid development of my country's road transport and the popularization of automobile trailer transport, semi-trailers have become the main means of transport for road freight. A semi-trailer tractor is a commercial vehicle equipped with special devices for towing a semi-trailer, including a tractor with driving ability and a trailer without driving ability towed by the tractor. There are two ways to connect the tractor and the trailer, namely semi-trailer and full-trailer. The semi-trailer is a trailer with the front part placed on the tractor saddle at the rear of the tractor, and the bridge behind the tractor bears part of the weight of the trailer.

[0003] After searching, it was found in the Chinese Utility Model Patent Publication No. CN219115599U that a high-strength tractor saddle is disclosed, in which a long wing plate is arranged at the front frame plate which is subjected to greater stress to share more stress; a short wing plate is arranged at the rear frame plate which is subjected to relatively less stress to share relatively less stress; the long wing plate and the short wing plate are arranged according to the stress distribution, and while achieving the same effect, the mass of the reinforcing plate is reduced, the weight of the saddle is reduced, and the arrangement is reasonable; and weight-reducing holes are opened on the plate body which is subjected to the least stress distribution to further reduce the weight of the saddle. However, most existing traction saddles are of an integrated structure, so that the saddle needs to be replaced as a whole after being damaged, which increases the maintenance cost. At the same time, the position of the saddle cannot be adjusted during docking, and the installation speed is slow. Therefore, a combined and position-adjustable saddle is needed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-7 As shown, a coupled adjustment type semi-trailer tractor saddle includes a mounting platform 1, a saddle 2 is fixedly connected to the upper surface of the mounting platform 1, a cover plate 3 is fixedly connected to the upper surface of the saddle 2, a wear-resistant sleeve 4 is fixedly connected to the inner wall of the cover plate 3, a movable seat 6 is fixedly connected to the lower surface of the mounting platform 1, and a slide rail 7 is movably connected to the inner wall of the lower surface of the movable seat 6.

[0028] During specific use, the tractor saddle is composed of the saddle 2, the cover plate 3 and the wear-resistant sleeve 4 through the arrangement of the mounting platform 1, the saddle 2, the cover plate 3, the wear-resistant sleeve 4, the groove 14, the protrusion 15, the fixing hole 16 and the fixing nail 17. The wear-resistant sleeve 4 is mainly in contact with the connecting pin. After the saddle and the connecting pin are installed, the contact position is easily worn, so the wear-resistant sleeve 4 is in contact with the connecting pin, which not only improves the wear resistance of the saddle, but also makes it more convenient to replace it separately after subsequent damage. The protrusion 15 under the cover plate 3 is inserted into the groove 14 of the saddle 2. After the two are fitted together, the fixing holes 16 correspond to each other. The fixing nail 17 is used in the fixing hole 16 to fix the two together. The wear-resistant sleeve 4 is fixed in the cover plate 3. Therefore, after the saddle is damaged, a certain component of the saddle can be replaced separately, and there is no need to replace the entire saddle as a whole, thereby reducing the maintenance and replacement cost.

[0029] In this embodiment, the outer surface of the mounting platform 1 is movably connected to a housing 5 , and a top groove 22 is formed on the upper surface of the housing 5 .

[0030] During specific use, the top groove 22 is provided to facilitate movement of the mounting platform 1 .

[0031] In this embodiment, a mounting groove 23 is formed on the lower surface of the housing 5 , and the inner wall of the mounting groove 23 is fixedly connected to the bottom plate 8 .

[0032] During specific use, the base plate 8 is installed through the installation groove 23 .

[0033] In this embodiment, an insertion hole 9 is formed on the inner wall of the movable seat 6 , a hydraulic rod 10 is fixedly connected to the inner wall of the insertion hole 9 , and a fixing sleeve 11 is fixedly connected to the outer surface of the hydraulic rod 10 .

[0034] During specific use, the hydraulic rod 10 is used to push the movable seat 6 to move.

[0035] In this embodiment, a fixing groove 12 is formed on the upper surface of the movable base 6 , and a sliding groove 13 is formed on the lower surface of the movable base 6 .

[0036] During specific use, the sliding groove 13 is provided to facilitate the sliding of the movable seat 6 .

[0037] In this embodiment, a groove 14 is formed on the upper surface of the saddle 2 , and a protrusion 15 is fixedly connected to the lower surface of the cover plate 3 .

[0038] During specific use, the saddle 2 and the cover plate 3 are connected together by the arrangement of the groove 14 and the protrusion 15 .

[0039] In this embodiment, fixing holes 16 are formed on the upper surfaces of the saddle 2 and the cover plate 3 , and fixing nails 17 are fixedly connected to the inner walls of the fixing holes 16 .

[0040] During specific use, the saddle 2 and the cover plate 3 are fixed together by setting the fixing nails 17.

[0041] In this embodiment, a pin 20 is fixedly connected to the side of the housing 5, and a through hole 21 is defined on the upper surface of the pin 20; a pin 2 18 is fixedly connected to the side of the base plate 8, and a through hole 2 19 is defined on the upper surface of the pin 2 18.

[0042] During specific use, the housing 5 is fixed by setting the pin 1 20 .

[0043] Working principle: The tractor saddle is composed of a saddle 2, a cover plate 3 and a wear-resistant sleeve 4. The wear-resistant sleeve 4 is mainly in contact with the connecting pin. After the saddle and the connecting pin are installed, the contact position is easily worn, so the wear-resistant sleeve 4 is in contact with the connecting pin, which not only improves the wear resistance of the saddle, but also facilitates the subsequent replacement after damage. The protrusion 15 under the cover plate 3 is inserted into the groove 14 of the saddle 2. After the two are well fitted, the fixing holes 16 correspond to each other. The fixing nails 17 are used in the fixing holes 16 to fix the two together. The wear-resistant sleeve 4 is fixed in the cover plate 3, so after the saddle is damaged, a certain component can be replaced separately; hydraulic rods 10 are fixed in the two sockets 9 on the moving seat 6, and the two hydraulic rods 10 are opposite. When adjusting the position of the saddle, one hydraulic rod 10 contracts and the other extends to make the moving seat 6 move on the slide rail 7. The movement drives the mounting platform 1 and the saddle to move at the same time, which is convenient for the saddle and the connecting pin to be connected together.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
