[0022] In one embodiment, see Figure 1 to Figure 2 As shown, the utility model provides a test bench for reliability testing of a communication vehicle, comprising a lower base 1 and four groups of symmetrically arranged wheel body support modules, the wheel body support module comprising a telescopic drive cylinder 2 and a support frame 3 mounted on the lower base 1 along a vertical sliding manner, the telescopic drive cylinder 2 and the lower base 1 are fixedly connected by bolts, the telescopic end of the telescopic drive cylinder 2 and the support frame 3 are fixedly connected by bolts, a transverse support wheel group 4 and a side support wheel group 5 are fixed on the support frame 3, the rotation center line of the transverse support wheel group 4 is arranged along the length direction of the support frame 3, and the rotation center line of the side support wheel group 5 intersects with the rotation center line of the transverse support wheel group 4. Among them, the transverse support wheel group 4 is used to support the outer ring of the wheel of the communication vehicle so that the wheel of the communication vehicle can rotate; the side support wheel group 5 is used to support the side wall of the wheel of the communication vehicle to prevent the wheel from deflecting, so that the wheel of the communication vehicle can remain in the transverse support wheel group 4.

[0023] Specifically, the cooperation between the lateral support wheel group 4 and the side support wheel group 5 of the utility model realizes the support of the communication vehicle, and serves as a carrier for the reliability test of the communication vehicle.

[0032] As an example, see Figures 1 to 4 As shown, a first side connecting plate 32 is fixed to one side of the accommodating groove 31 , and the first side connecting plate 32 is fixedly connected to the first bearing seat 43 by bolts.

[0033] In general, the utility model supports the communication vehicle through the cooperation of the lateral support wheel group 4 and the side support wheel group 5. It has good structural strength and less spatial structure, which ensures the detection accuracy and safety performance of the reliability test of the communication vehicle.
