[0026] The following is a combination of the appended examples of the present invention Figure 1-Figure 5 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figure 1-Figure 5 As shown, the utility model provides a trailer frame with a suspension, including a frame body, the frame body including a main frame 1, a wheel support frame 2 and a flat bracket 3, wheel support frames 2 are installed on both sides of the bottom of the main frame 1, and wheel bodies 4 are installed inside the wheel support frames 2. The wheel support frames 2 are connected to the main frame 1 through a connecting shaft 5, and the main frame 1 is equipped with a flat bracket 3 on the upper part of the wheel support frame 2. The wheel support frames 2 located on both sides of the main frame 1 are separately connected and supported with the wheel bodies 4, which is not only stable in connection but also convenient for maintenance of the wheels. The connecting shaft 5 facilitates connecting the wheels to the main frame 1, has high connection stability, and can play a buffering role. The axle is not easy to break, and the vehicle has good service life and safety performance.

[0029] The wheel support frame 2 includes a U-shaped connecting rod 21 and a support rod 22. The opening of the U-shaped connecting rod 21 is connected to the connecting shaft 5. The wheel body 4 is installed in the middle of the U-shaped connecting rod 21, and the support rod 22 is installed above the U-shaped connecting rod 21. The longitudinal section of the support rod 22 is triangular. The top of the support rod 22 is connected to the main frame 1 through the shock absorbing assembly 6. The U-shaped connecting rod 21 can play a good connecting and supporting role and protect the wheel body 4, ensuring that the two wheels move independently during movement without interfering with each other. In addition, the triangular connecting rod has a good supporting effect, and the shock absorbing assembly 6 can play a good shock absorbing effect, further improving the stability of the trailer.

[0030] The connecting shaft 5 is connected to the main frame 1 via a fixing frame 7, and the middle part of the fixing frame 7 is connected to the connecting shaft 5 via a bearing 8. A torsion balancing shaft 51 is provided in the middle part of the connecting shaft 5. The connection between the connecting shaft 5 and the main frame 1 connected via the fixing frame 7 has high connection stability, and the connection via the bearing 8 facilitates movement. The torsion balancing shaft 51 in the middle part of the connecting shaft 5 is beneficial to improving the anti-roll capability of the trailer.

[0031] The shock absorbing assembly 6 includes a shock absorber 61 and a shock absorbing spring 62. One end of the shock absorber 61 is hinged to the main frame 1, and the other end is hinged to the support rod 22. The shock absorbing spring 62 is installed on the outside of the shock absorber 61. Through the cooperation between the shock absorber 61 and the shock absorbing spring 62, the vibration of the vehicle during driving can be greatly alleviated, and the stability of the vehicle movement can be improved.

[0032] Through the above structure, a semi-independent suspension connection is achieved between the wheel support frame 2 and the wheel body 4 and the main frame 1.

[0033] The vehicle as a whole is connected to the left and right wheel bodies 4 through the wheel support frames 2 on the left and right sides, and is then connected to the main frame 1 through the shock-absorbing assembly 6 on the wheel support frame 2, thereby forming a buffering effect of such a shock-absorbing assembly 6. On the one hand, the wheel support frame 2 is connected to the main frame 1 through the shock-absorbing assembly 6 and has relative independence when in use. During movement, the connecting shaft 5 and the shock-absorbing assembly 6 jointly play a role in resisting torque, and play a role in supporting anti-roll when turning with shock absorption.

[0034] Example 2:

[0035] Reference Figure 4 and Figure 5The difference between this embodiment and embodiment 1 is that a front wheel frame 9 is provided on the front side of the main frame 1, and the front wheel frame 9 includes a front wheel connecting frame 91, a suspension link 92 and a front wheel support frame 93. Suspension links 92 are provided on both sides of the front wheel connecting frame 91. The front wheel support frame 93 is installed on the side of the suspension link 92 away from the front wheel connecting frame 91. The wheel body 4 is installed inside the front wheel support frame 93. The front wheel connecting frame 91 and the front wheel support frame 93 are connected together by the suspension link 92, which has a good buffering and shock absorption effect.

[0036] A shock absorbing assembly 6 is also provided between the front wheel support frame 93 and the front wheel connecting frame 91. The use of the shock absorbing assembly 6 can further improve the vehicle's buffering and shock absorption effect. The shock absorbing assembly 6 has the same structure as the shock absorbing assembly 6 in Example 1. One end of the shock absorber 61 is hinged to the front wheel support frame 93, and the other end is hinged to the front wheel connecting frame 91.

[0037] A rotation support platform 94 is provided above the front wheel connecting frame 91 , and the rotation support platform 94 is connected to the main frame 1 . The front wheel connecting frame 91 and the main frame 1 are connected together by the rotation support platform 94 , and the connection stability is high.

[0038] Through the above structure, a completely independent suspension connection is achieved between the front wheel support frame 93, the wheel body 4 and the front wheel frame 9.

[0039] In summary, the independent suspension of the front and rear wheels of the trailer frame ensures complementary interference between the wheels, and ensures the independent operation of the wheels through the wheel support frame 2, thereby improving the stability of the vehicle's driving, and improving the stability of the frame through the shock absorbing assembly 6 and the torsion balance shaft 51.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
