A buffer assembly 4 is installed between the fixed platform 2 and the chassis 1. Suspension assemblies 5 are installed on both sides of the chassis 1.

[0026] See Figures 2-4 Furthermore, the buffer assembly 4 includes two sets of polyurethane blocks 6, which are respectively installed at the front and rear ends between the chassis 1 and the fixed platform 2. Two linear bearings 7 are installed at the front end between the chassis 1 and the fixed platform 2. Rectangular springs 8 are installed on the outside of the linear bearings 7. A support frame 9 is fixedly installed at the bottom of the chassis 1. Ground wheels 10 are movably installed on both sides of the bottom of the support frame 9. An obstacle-crossing wheel 11 is movably installed in the center of the bottom of the support frame 9.

[0027] The chassis 1 and the fixed platform 2 are equipped with identical linear bearings 7 and rectangular springs 8 at the rear end. There are two polyurethane blocks 6 in each group. The polyurethane blocks 6 are sandwiched between the chassis 1 and the fixed platform 2 to provide support and cushioning.

[0028] The two linear bearings 7 at the front end are located on both sides of the two polyurethane blocks 6, and the linear bearing 7 at the rear end is located between the two polyurethane blocks 6. The linear bearings 7 slide vertically through the rectangular springs 8, forming an elastic energy-absorbing damping.

[0029] The obstacle-crossing wheel 11 is located between the two ground-touching wheels 10. The height of the obstacle-crossing wheel 11 is higher than that of the two ground-touching wheels 10, thereby improving the overall obstacle-crossing capability.

[0030] Specifically, the fixed platform 2 is supported on the top of the chassis 1 by two sets of polyurethane blocks 6, the linear bearing 7 slides through the rectangular spring 8 to provide vertical freedom, so that the chassis 1 and the fixed platform 2 form elastic energy-absorbing damping to reduce the vibration of the radar body 3, the ground wheel 10 contacts the ground for rolling support, and the obstacle-crossing wheel 11 provides obstacle-crossing capability.

[0031] Example 2

A damper 15 is installed between the rear end of the suspension frame 12 and the chassis 1.

[0033] The suspension frame 12 is movably connected to the chassis 1 via a connecting shaft 13. The suspension frame 12 rotates on the outside of the chassis 1, causing the drive wheel 14 to be suspended on the outside.

[0034] The drive wheel 14 is connected to the suspension frame 12 via a pivot shaft. The drive wheel 14 is connected to the damper 15 to provide damping, so that the drive wheel 14 is independently suspended, reducing the impact of tire tread.

[0035] Specifically, the drive wheel 14 is driven to rotate by an internal drive system, the suspension frame 12 is connected by a connecting shaft 13, and the damper 15 is used to provide damping so that the drive wheel 14 is independently suspended and connected to the chassis 1, reducing the impact of tire treads on the radar body 3.
