The terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 5 As shown, this utility model discloses a vehicle with damping, including a main frame 1 and a side frame 2. The side frame 2 is located on one side of the main frame 1 and is hinged to the main frame 1. A main wheel 10 is installed at the lower end of the main frame 1, and a side wheel 11 is installed on the side frame 2 to ensure normal vehicle operation. The main frame 1 is connected to a truck bed 3 via a connecting rod 9. The truck bed 3 is installed on a first base 4 and a second base 6. The first base 4 and the second base 6 are hinged to the side frame 2. A first damper is installed on the first base 4, and a second damper is installed on the second base 6. The damping direction of the first damper is opposite to that of the second damper. When the truck bed 3 tilts to the left or right, damping is applied respectively to ensure the stability of the truck bed 3 when tilted and to ensure the safety of vehicle operation.

[0020] The damped vehicle also includes a hydraulic damping rod 8, one end of which is hinged to the main frame 1 and the other end to the side frame 2. The hydraulic damping rod 8 controls the tilt of the main frame 1 during cornering, reducing the speed and angle of tilt, ensuring stability during cornering, and improving vehicle safety.

[0021] In this embodiment, the first base 4 includes two triangular support plates and a connecting plate located between the two support plates. The truck bed 3 is mounted on the connecting plate. The two support plates of the first base 4 are hinged to the side frame 2 via a first hinge shaft. The triangular support plates ensure that the truck bed 3 can tilt synchronously with the main frame 1 when turning, improving the driving experience. The first damper is a first torsion spring 5, which is mounted on the first hinge shaft. The first torsion arm at one end of the first torsion spring 5 is engaged with the support plate of the first base 4, and the second torsion arm at the other end is bent and engaged with the first crossbar 12 of the side frame 2. The first and second torsion arms of the first torsion spring 5 are located on the side away from the main frame 1. When the truck bed 3 tilts to the side away from the main frame 1, i.e., tilts to the right, the first torsion spring 5 applies damping torque to the first base 4, thereby reducing the tilting speed of the truck bed 3. The hydraulic damping rod 8 is subjected to compressive force to form tilt damping, reducing the tilting speed of the main frame 1, ensuring stability when turning, and improving the safety of vehicle driving.

[0022] In this embodiment, the second base 6 is located at the rear end of the first base 4. The second base 6 includes two triangular support plates and a connecting plate located between the two support plates. The truck bed 3 is mounted on the connecting plate. The second base 6 is hinged to the side frame 2 via a second hinge shaft. The second damper is a second torsion spring 7, which is mounted on the second hinge shaft. The first torsion arm at one end of the second torsion spring 7 is engaged with the support plate of the second base 6, and the second torsion arm at the other end is bent and engaged with the second crossbar 13 of the side frame 2. The first and second torsion arms of the second torsion spring 7 are located on the side closer to the main frame 1. When the truck bed 3 tilts towards the main frame 1, i.e., tilts to the left, see [reference needed]. Figure 2 As shown, the first torsion spring 5 is in a stretched state and does not exert a damping effect, while the second torsion spring 7 is compressed and exerts a damping effect. The second torsion spring 7 applies a damping torque to the second base 6, thereby reducing the tilting speed of the truck bed 3. The hydraulic damping rod 8 is subjected to tension to form tilt damping. The hydraulic damping rod 8 applies damping to the main frame 1. By applying damping force to the main frame 1 and the truck bed 3, the stability of the vehicle when turning is ensured, and the safety of the vehicle driving is improved.

[0023] Furthermore, the first torsion spring 5 and the second torsion spring 7 have the same torque value, both being 900-1000 N·m / rad, ensuring the damping effect on the truck bed 3. The first torsion spring 5 and the second torsion spring 7 can assist the hydraulic damping rod 8 in applying damping to the left and right sides of the truck bed 3, ensuring the stability and safety of driving.

[0024] In an optional embodiment, the first torsion arm and the second torsion arm of the first torsion spring 5 are located on the side closer to the main frame 1, and the first torsion arm and the second torsion arm of the second torsion spring 7 are located on the side farther away from the main frame 1, which can also achieve the effect of applying damping to the left and right sides of the truck bed 3.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
