[0034] In order to adapt to the complex working environment, the rear axle of the telescopic arm forklift usually adopts a free swinging form. In order to avoid direct collision between the vehicle body and the bridge body, the prior art provides a vehicle bridge frame with a body shock absorber to absorb side collision energy. Buffer plates are placed on the front and rear sides of the bottom of the vehicle bridge frame. The buffer plates are arranged on the vehicle body. When the bridge frame swings relative to the vehicle body, the buffer plates provide buffering to avoid direct collision between the vehicle body and the bridge frame. However, there is a problem that with the direct collision between the vehicle body and the bridge frame, the connection between the buffer plate and the vehicle body is easily loosened, and since the buffer plate is subjected to a large impact force, it is also easy to cause the buffer plate to tear.
[0035] In view of the above problems, the present embodiment provides an axle swing limit structure to solve the problem in the prior art that the connection between the buffer plate and the vehicle body is easily loosened due to the direct collision between the vehicle body and the bridge frame, and the buffer plate is easily torn due to the large impact force. The structure can be used in the field of vehicle technology, specifically in telescopic arm forklifts or other types of vehicles.
[0036] Reference Figure 1 The axle swing limit structure is used to limit the swing amplitude of the axle 200 relative to the vehicle body 100. The axle swing limit structure specifically includes a first limit block 1 and a second limit block. The first limit block 1 is used to be set on the vehicle body 100. The first limit block 1 has two installation surfaces set at intervals. The two installation surfaces are used to be installed on both sides of the vehicle body 100 respectively, so that when the first limit block 1 is installed on the vehicle body 100, the connection structure strength between the first limit block 1 and the vehicle body 100 is enhanced. The second limit block is used to be set on the axle 200. The axle 200 can swing relative to the vehicle body 100 and has an initial position and a set swing position. The designer can set the set swing position according to the swing amplitude allowed by the axle 200. When the axle 200 is located at the set swing position, the first limit block 1 abuts against the second limit block, so that when the axle 200 moves to the set swing position, the first limit block 1 can limit the second limit block to prevent the axle 200 from continuing to move. At the same time, the axle 200 will not directly contact the first limit block 1. When the axle 200 is at the initial position, the first limit block 1 is separated from the second limit block. The swing limit structure of the axle can enhance the strength of the connection structure between the first limit block 1 and the vehicle body 100, and prevent the first limit block 1 from being damaged and torn when subjected to a large impact force; at the same time, the axle 200 will not directly contact the first limit block 1, and damage to the axle 200 and the components on the axle 200 can be avoided.
[0037] Reference Figure 1-Figure 2The first limit block 1 has a mounting groove 11, the mounting groove 11 has two side walls 112 arranged at intervals and a bottom wall 111 located between the two side walls 112, the mounting surface is the side wall 112, the two side walls 112 are used to be installed on both sides of the vehicle body 100 respectively, and the bottom wall 111 is used to be installed on the vehicle body 100, so that the three groove walls of the mounting groove 11 are connected to the vehicle body 100, so as to further increase the connection structure strength between the first limit block 1 and the vehicle body 100.
[0038] Continue to refer to Figure 1-Figure 2 The bottom wall 111 and the two side walls 112 are welded to the vehicle body 100 , and a solder receiving groove 113 is opened between the bottom wall 111 and any side wall 112 , and the solder receiving groove 113 is used to receive solder to improve the welding effect.
[0039] Continue to refer to Figure 1 The first limit block 1 has a first abutting surface, and the second limit block has a second abutting surface. When the axle 200 is at the set swing position, the first abutting surface fits with the second abutting surface, so that when the first limit block 1 abuts with the second limit block, the contact area between the two is increased to reduce the impact. The designer can set the maximum swing angle θ of the axle 200 according to the actual situation. That is, when the axle 200 swings from the initial position to the preset swing position, the swing angle of the axle 200 is θ, then when the axle 200 is at the initial position, the angle between the first abutting surface and the second abutting surface is also θ.
[0040] Continue to refer to Figure 1 There are two first limit blocks 1 and two second limit blocks. The set swing position of the axle 200 includes a left swing position and a right swing position. When the axle 200 moves from the left swing position to the right swing position, it passes through the initial position. When the axle 200 is at the left swing position, one of the first limit blocks 1 abuts against one of the second limit blocks. When the axle 200 is at the right swing position, the other first limit block 1 abuts against the other second limit block, thereby limiting the swing of the axle 200 in the left and right directions to improve the adaptability of the axle 200 to the driving road surface.
[0041] Continue to refer to Figure 1 , a buffer pad is provided on the side of the first limit block 1 close to the second limit block; and / or a buffer pad is provided on the side of the second limit block close to the first limit block 1 to further reduce the impact force generated when the two contact. The first limit surface or the second limit surface is the surface of the buffer pad. This embodiment exemplarily provides a solution in which both the first limit block 1 and the second limit block are provided with a buffer pad.
[0042] Reference Figure 1 as well as Figure 3One structure of the second limit block is a pad 2 provided on the axle 200, the surface of the pad 2 away from the first limit block 1 is in contact with the axle 200, and the surface of the pad 2 close to the first limit block 1 is the second limit surface. Optionally, the pad 2 is provided with a threaded hole and can be connected to the axle 200 by bolts. Optionally, round chamfers are provided between the surfaces of the pad 2 to reduce the wear of the pad 2 on the wiring harness near the axle 200.
[0043] Reference Figure 1 as well as Figure 4 Another structure of the second limit block is a shield 3 arranged on the axle 200. The shield 3 has a receiving groove 301. The receiving groove 301 is used to receive components arranged on the axle 200. When other components are arranged at the position corresponding to the first limit block 1 on the axle 200, the shield 3 can replace the pad 2. While being able to abut against the first limit block 1 to limit the axle 200, it can also play a role in protecting the components.
[0044] Continue to refer to Figure 1 as well as Figure 4 The shield 3 includes a mounting plate 31 and a U-shaped plate 32 arranged on the mounting plate 31. The U-shaped plate 32 includes two side plates 322 and a bottom plate 321 arranged between the two side plates 322. The bottom plate 321 and the two side plates 322 form a receiving groove 301. The arrangement of the U-shaped plate 32 facilitates the laying of the component harness. Two mounting plates 31 are provided. The two side plates 322 are respectively connected to the two mounting plates 31. Both mounting plates 31 are used to be installed on the axle 200. Among them, the second limiting surface is located on the bottom plate 321, which is used to abut against the first limiting surface of the first limiting block 1. Optionally, both mounting plates 31 are provided with threaded holes and can be connected to the axle 200 by bolts. The U-shaped plate 32 is correspondingly provided with bolt installation avoidance holes. Optionally, round chamfers are provided between the two side plates 322 and the bottom plate 321 of the U-shaped plate 32 to reduce the wear of the U-shaped plate 32 on the harness near the axle 200.
[0045] The present embodiment also provides a vehicle, including the above-mentioned axle swing limiting structure, and also including a vehicle body 100 and an axle 200, wherein the axle 200 can swing relative to the vehicle body 100, and the axle swing limiting structure is used to limit the swing amplitude of the axle 200 relative to the vehicle body 100. The axle 200 can swing relative to the vehicle body 100 and has an initial position and a set swing position, when the axle 200 is at the set swing position, the first limit block 1 abuts against the second limit block, and when the axle 200 is at the initial position, the first limit block 1 is separated from the second limit block. The axle swing limiting structure can enhance the strength of the connection structure between the first limit block 1 and the vehicle body 100, and prevent the first limit block 1 from being damaged and torn when subjected to a large impact force; at the same time, the axle 200 will not directly contact the first limit block 1, and damage to the axle 200 and components on the axle 200 can be avoided.
