Description

Technical Field

[0001] This utility model relates to the technical field of suspension device structure for semi-trailer tractors, and in particular to a suspension device structure for a pure electric semi-trailer tractor. Background Technology

[0002] The suspension is a general term for all force-transmitting connection devices between the car frame and the axle. Its function is to transmit the force and torque acting between the wheels and the frame, and to buffer the impact force transmitted from uneven road surfaces to the frame or body, and reduce the vibration caused thereby, so as to ensure that the car can drive smoothly.

[0003] As electric vehicle sales are gradually increasing, and considering that the energy density of batteries used in electric vehicles is much lower than that of traditional gasoline vehicles, and that the introduction of batteries significantly increases the overall weight of the vehicle, pure electric semi-trailer tractors often adopt lightweight structures.

[0004] The existing suspension system structure for pure electric semi-trailer tractors reduces weight, thus reducing load-bearing capacity. Therefore, it is necessary to design a lightweight suspension system structure that can bear more weight. Utility Model Content

[0005] Therefore, it is necessary to provide a suspension device structure for a pure electric semi-trailer tractor to address the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides a suspension device structure for a pure electric semi-trailer tractor, including a body, an upper support plate, and a lower support plate. The upper and lower support plates are connected by a connecting rod. A pressure block is installed on the upper support plate, and a sliding groove is provided on the body. The pressure block is slidably engaged in the sliding groove. Two sliders are slidably connected in the sliding groove, with the sliders facing each other. The pressure block and sliders abut against each other. A pressure block is installed on the lower support plate, and a sliding groove is provided on the body. The pressure block is slidably engaged in the sliding groove. Two sliders are slidably connected in the sliding groove, with the sliders facing each other. The pressure block and sliders abut against each other.

[0007] Preferably, there are two of each of the first and second slides, and both are through slides. The first pressure block is threadedly mounted on the upper support plate by a bolt, and the second pressure block is threadedly connected to the lower support plate by a bolt.

[0008] Preferably, it also includes abutting block one and abutting block two, with both ends of abutting block one abutting block one and both ends of abutting block two abutting block two.

[0009] Preferably, the connecting rod can be a threaded rod, and a limit nut is installed on the connecting rod.

[0010] Preferably, both bolt one and bolt two are countersunk bolts.

[0011] Preferably, the pressure block is provided with a pressure-resistant layer.

[0012] Preferably, each of the pressure blocks is provided with a pressure-resistant layer.

[0013] Preferably, the main body is provided with a plurality of supporting inclined plates, which are located between the upper support plate and the lower support plate.

[0014] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0015] 1. By cooperating with the first pressure block and the first slider, and the second pressure block and the second slider, the pressure on the suspension can be converted into a lateral force by the first pressure block squeezing the second slider and the second pressure block squeezing the second slider, thereby improving the load-bearing capacity of the suspension.

[0016] 2. The upper and lower support plates are movably mounted on the main body, which facilitates their replacement. Furthermore, the load-bearing pressure on the upper support plate is reduced so that the lower support plate no longer bears the pressure only at the welded end near the connecting rod during welding, but rather the entire lower support plate bears the pressure. This further improves the load-bearing capacity of the suspension. Attached Figure Description

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 3 This application provides a suspension device structure for a pure electric semi-trailer tractor, including a body 1, an upper support plate 2, and a lower support plate 3. The body 1 adopts a hollow structure to maintain its lightweight. The upper support plate 2 and the lower support plate 3 are connected by a connecting rod 4. A pressure block 5 is installed on the upper support plate 2. The body 1 is provided with a sliding groove 6. The pressure block 5 is slidably engaged in the sliding groove 6. Two sliders 7 are slidably connected in the sliding groove 6. The sliders 7 are arranged opposite to each other. The pressure block 5 abuts against the sliders 7. A pressure block 8 is installed on the lower support plate 3. The body 1 is provided with a sliding groove 9. The pressure block 8 is slidably engaged in the sliding groove 9. Two sliders 10 are slidably connected in the sliding groove 9. The sliders 10 are arranged opposite to each other. The pressure block 8 abuts against the sliders 10.

[0023] In this embodiment, the frame can be welded onto the upper support plate 2. Part of the pressure from the frame is transmitted to the body 1 via the upper support plate 2, and another part of the pressure is transmitted to the lower support plate 3 via several connecting rods 4 installed between the upper support plate 2 and the lower support plate 3. Compared to traditional U-shaped welded connections, this allows the pressure on the upper support plate 2 to be transmitted to the lower support plate 3, rather than only the welded side of the lower support plate 3 being stressed. When the upper support plate 2 is under pressure, it drives the pressure block 5 downwards, causing the pressure block 5 to exert pressure on the two opposing sliders 7 within the slide groove 6. Through the inclined structure of the pressure blocks 5 and 7, part of the pressure on the slider 7 is transmitted downwards to the body 1, and part is transmitted horizontally to the body 1 through the contact between the slider 7 and the inner wall of the slide groove 6. Thus, by distributing the pressure vertical to the body 1, the load-bearing capacity is improved. The downward pressure from the lower support plate 3 is distributed horizontally through the special inclined structure of the pressure block 28 and the slider 20. The pressure block 28 squeezes the slider 20, and then the slider 20 squeezes the inner wall of the groove 29 on the body 1, thereby further improving the load-bearing capacity of the body 1.

[0024] In some embodiments, to facilitate the insertion of pressure block 5 and pressure block 8 into slide groove 7 and slide groove 9, two slide grooves 6 and 9 are provided, and both are through grooves. Pressure block 5 is threadedly mounted on the upper support plate 2 by bolt 11, and pressure block 8 is threadedly connected to the lower support plate 3 by bolt 212. The through grooves 6 and 9 allow pressure block 5 and pressure block 8 to be inserted into them from the center, thus enabling contact with slider 7 and slider 10. Furthermore, to facilitate the connection between pressure block 5 and pressure block 8 and the upper and lower support plates 2 and 3 after installation, bolts 11 and 22 are used to thread them onto the upper and lower support plates 2 and 3.

[0025] In some embodiments, to facilitate the connection between pressure block 5 and pressure block 8 and bolts 11 and 12, abutment block 13 and abutment block 24 are also provided. Both ends of abutment block 13 abut against pressure block 5, and both ends of abutment block 24 abut against pressure block 8. After installing the two pressure blocks 5 or pressure blocks 8 into the slide groove 6 or slide groove 9, abutment blocks 13 and abutment blocks 24 are pressed down to insert them between the two upper support plates 2 and lower support plates 3. Thus, abutment blocks 13 and abutment blocks 24 can abut against pressure blocks 5 and pressure blocks 8, thereby avoiding affecting the force transmission effect of pressure blocks 5 and pressure blocks 28 and facilitating alignment of the mounting holes of bolts 11 and 12.

[0026] In some embodiments, to facilitate the transmission of pressure by the connecting rod 4, the connecting rod 4 can be a threaded rod, and a limiting nut 18 is installed on the connecting rod 4. In this case, the connecting rod 4 is threadedly connected to both the upper support plate 2 and the lower support plate 3, so force can be transmitted through the connecting rod 4. Welding can also be used, and the limiting nut 18 facilitates the threaded connection or welding of the connecting rod 4.

[0027] In some embodiments, to facilitate the installation of the frame on the upper support plate 2, bolts 11 and 12 are both countersunk bolts.

[0028] In some embodiments, to prevent the pressure block 5 from being damaged during the transmission of extrusion pressure, a pressure-resistant layer 17 is provided on the pressure block 5.

[0029] In some embodiments, to prevent the pressure block 8 from being damaged during the transmission of extrusion pressure, a pressure-resistant layer 18 is provided on each pressure block 8.

[0030] In some embodiments, in order to improve the load-bearing strength of the body 1 itself, a plurality of supporting inclined plates 17 are provided on the body 1, and the supporting inclined plates 17 are located between the upper supporting plate 2 and the lower supporting plate 3.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
