DETAILED DESCRIPTION

[0024] The vehicle suspension device is an important part of the automobile chassis. It connects the axle and the frame through the stabilizer bar assembly to limit the roll and torsion of the vehicle. At present, the connection between the stabilizer bar assembly and the frame is at a high position, there are many obstacles near the connection, and the reserved operating space is small, which makes the installation and maintenance convenience of the stabilizer bar assembly poor. The present application provides a vehicle suspension device and a vehicle to solve the above problems.

[0025] like Figure 1 As shown, the present application provides a vehicle suspension device, including a frame 10, an axle 20 and a stabilizer bar assembly 30. The frame 10 includes a chassis 11 and a frame 12 extending downward from the chassis 11, and the axle 20 is located below the chassis 11 and disposed on one side of the frame 12.

[0026] The frame 12 is provided with a frame connection position 120, and the frame connection position 120 is located between the top and the bottom of the frame 12. In the vehicle height direction, the distance between the frame connection position 120 and the bottom is smaller than the distance between the frame connection position 120 and the top.

[0027] The stabilizer bar assembly 30 includes a stabilizer bar 31 , axle connectors 32 disposed at both ends of the stabilizer bar 31 , and a frame connector 33 disposed between the two ends of the stabilizer bar 31 . The frame connector 33 is connected to the frame connection position 120 , and the axle connector 32 is connected to the axle 20 .

[0028] Since the distance between the frame connection position 120 and the bottom of the frame 12 is smaller than the distance between the frame connection position 120 and the top of the frame 12, the height of the connection between the stabilizer bar assembly 30 and the frame 10 is reduced, avoiding positions with many interfering parts, and improving the convenience of disassembly and assembly of the vehicle suspension device, making it easy to install and maintain.

[0029] On the other hand, the frame connection position 120 is located between the top and the bottom of the skeleton 12, and is at a certain distance from the bottom of the skeleton 12, thereby preventing the connection between the stabilizer bar assembly 30 and the frame 10 from being too low, preventing the stabilizer bar assembly 30 from scraping against the ground during movement, and improving the safety of the vehicle suspension device.

[0030] The distance between the frame connection position 120 and the top of the frame 12 may refer to: in the height direction, the distance between the midpoint of the frame connection position 120 and the top of the frame 12, that is, Figure 1 The distance between the frame connection position 120 and the bottom of the frame 12 may refer to: the distance between the midpoint of the frame connection position 120 and the bottom end of the frame 12 in the height direction, that is, Figure 1 The L2 distance is shown.

[0031] like Figure 1 As shown, the skeleton 12 may include a first section 121 and a second section 122. One end of the first section 121 is connected to the chassis 11, the second section 122 connects the first section 121 and the chassis 11, and the frame connection position 120 is arranged at the second section 122. The chassis 11 may be arranged horizontally, the first section 121 may be arranged vertically, and the second section 122 may be obliquely connected between the chassis 11 and the first section 121. The frame connection position 120 may be a plane area on the second section 122.

[0032] By connecting the second section 122 between the first section 121 and the chassis 11, the second section 122 can strengthen the vehicle suspension device and improve the strength of the vehicle suspension device. The frame 12 can be welded from a rod structure. To further improve the strength of the vehicle suspension device, a plurality of reinforcing rods with different inclination angles can be arranged between the chassis 11 and the first section 121. The specific structural form of the frame 12 is not limited.

[0033] The frame connection position 120 can be tilted downwardly at the second section 122. The axle 20 is provided with a fixing surface 220 tilted upwardly. The frame connection member 33 is connected to the frame connection position 120, and the axle connection member 32 is connected to the fixing surface 220, so that the stabilizer bar 31 is tilted.

[0034] If the stabilizer bar 31 is set horizontally, when the vehicle is impacted in the front-to-back direction, the force on the stabilizer bar 31 is in the horizontal direction, lacking the force component in the vehicle height direction, making it difficult for the stabilizer bar 31 to rotate quickly. Similarly, if the stabilizer bar 31 is set vertically, when the vehicle is impacted in the height direction, the force on the stabilizer bar 31 is in the vertical direction, lacking the force component in the vehicle front-to-back direction, making it difficult for the stabilizer bar 31 to rotate quickly. When the stabilizer bar 31 is set at an angle, the stabilizer bar 31 can rotate quickly when it is subjected to forces in both the horizontal and vertical directions, thereby increasing the efficiency of the stabilizer bar assembly 30 in absorbing impacts and improving the vibration isolation effect of the vehicle suspension device.

[0035] like Figure 1 As shown, the axle 20 may include a main body 21 and a pair of arms 22 extending from the main body 21 toward the frame 12. The arm 22 is provided with an upward fixing surface 220, and the axle connector 32 is connected to the fixing surface 220. Since the axle connector 32 is connected to the fixing surface 220 of the arm 22, the stabilizer bar 31 is located above the arm 22, which increases the height of the stabilizer bar 31, further preventing the stabilizer bar 31 from scratching the ground during movement, and improving the safety of the vehicle suspension device.

[0036] At the same time, the stabilizer bar 31 is located in the space between the chassis 11 and the arm body 22, so that the distance between the stabilizer bar 31 and the arm body 22 is small, reducing the size of the axle connector 32 connected between the stabilizer bar 31 and the arm body 22, saving materials and reducing costs.

[0037] like Figure 2 As shown, the stabilizer bar 31 may be U-shaped. When impacted, the U-shaped stabilizer bar itself will bend to a certain extent to absorb a certain amount of energy and improve the vibration isolation effect of the vehicle suspension device. The specific shape of the stabilizer bar 31 is not limited.

[0038] The stabilizer bar 31 and the axle connection member 32, and the stabilizer bar 31 and the frame connection member 33 can be rotatably connected through a bolt, nut and washer structure. The stabilizer bar 31 can rotate with the left and right directions of the vehicle as the axis to absorb the bounce caused by the impact of the axle 20. Damping parts such as rubber bushings are provided between the stabilizer bar 31 and the axle connection member 32, and between the stabilizer bar 31 and the frame connection member 33 to further absorb the bounce caused by the impact of the axle 20.

[0039] The axle connector 32 may include a connecting plate 321 and a fixing block 322. The fixing block 322 includes a fixing plate 3221 and a fixing boss 3222 formed by protruding from the fixing plate 3221. The two ends of the connecting plate 321 are rotatably connected to the fixing boss 3222 and the stabilizer bar 31, respectively, and the fixing plate 3221 is connected to the axle 20. Specifically, the connecting plate 321 and the fixing boss 3222, and the connecting plate 321 and the stabilizer bar 31 may be rotatably connected through a bolt, nut and washer structure. The fixing plate 3221 may be connected to the fixing surface 220. The axle connector 32 is composed of a plurality of plate-type parts, and the structure of the plate-type parts is simple, which reduces the difficulty of processing the vehicle suspension device.

[0040] The axle connector 32 may include two connecting plates 321. The end of the stabilizer bar 31 and the fixing boss 3222 are clamped between the two connecting plates 321. By providing two connecting plates 321, the strength of the vehicle suspension device is improved, so that it can absorb more impact energy, and the vibration isolation effect of the vehicle suspension device is improved. In other embodiments, on each axle connector 32, the number of connecting plates 321 may also be set to only one. The specific number of connecting plates 321 is not limited.

[0041] The frame connector 33 may include a first portion 331 and a second portion 332. The first portion 331 is fixed to the frame 12. The second portion 332 is assembled to the first portion 331. The first portion 331 and the second portion 332 are surrounded to form a receiving hole 330, and the stabilizer bar 31 is disposed through the receiving hole 330. The first portion 331 and the second portion 332 may be semicircular and assembled to form a whole.

[0042] During manufacturing, the first part 331 can be pre-fixed to the frame 12, and then the stabilizer bar 31 and the second part 332 are installed, which improves the assembly efficiency of the vehicle suspension device. The first part 331 can be fixed to the frame 12 by carbon dioxide shielded welding, and the specific fixing method is not limited.

[0043] The frame connector 33 may further include a screw 333, and the first portion 331 and the second portion 332 are fixed by the screw 333. The first portion 331 and the second portion 332 are installed by a threaded structure, which has high connection strength and assembly efficiency, and is convenient for later disassembly and maintenance.

[0044] The first part 331 is provided with a threaded hole (not shown in the figure), and the second part 332 is provided with a through hole (not shown in the figure). The threaded hole and the through hole are arranged in alignment, and the screw 333 passes through the through hole and is fixedly connected to the threaded hole. The through hole can play a positioning role. The screw 333 first extends into the through hole and then cooperates with the threaded hole to be fixed, which can further improve the assembly efficiency of the vehicle suspension device.

[0045] The present application also provides a vehicle, including the above-mentioned vehicle suspension device. Since the above-mentioned vehicle suspension device has high disassembly and assembly convenience and safety, the vehicle of the present application also has high disassembly and assembly convenience and safety. The vehicle of the present application can be a low-floor bus with high passenger passability. The specific type of the vehicle is not limited.
