DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-4 As shown, the embodiment of the utility model provides a tractor chassis dual-machine loading running-in test bench, comprising:

[0026] The running-in test bench body 1, the bottom surface of the running-in test bench body 1 is fixedly connected to the support base 2, the starting component, the starting component includes a No. 1 rotating shaft 3 and two No. 2 rotating shafts 4 arranged in the support base 2, the No. 1 rotating shaft 3 is rotatably connected to the side walls of the support base 2 through a bearing, and the two No. 2 rotating shafts 4 are rotatably connected to the side walls of the support base 2 through bearings, the No. 1 rotating shaft 3 and the two No. 2 rotating shafts 4 are circumferentially fixedly connected with synchronous wheels 5, and a synchronous belt 6 is engaged between the three synchronous wheels 5. A rotating handle is fixedly connected to either end of the No. 1 rotating shaft 3 for convenience of operation by the staff, and the two No. 2 rotating shafts 4 are symmetrically arranged about the No. 1 rotating shaft 3, so that the running-in test bench body 1 has good stability when moving, and the three synchronous wheels 5 are concentrically arranged with the No. 1 rotating shaft 3 and the two No. 2 rotating shafts 4, respectively, to ensure that the three synchronous wheels 5 can perform meshing transmission;

[0027] Four telescopic moving components, all of which are located in the support seat 2, the telescopic moving component includes a worm 7 circumferentially fixedly connected to the second rotating shaft 4, the top surface of the support seat 2 is rotatably connected to a threaded rod 8, the threaded rod 8 is circumferentially fixedly connected to a worm wheel 9, the worm 7 and the worm wheel 9 are meshed, and a nut 10 is threadedly connected to the threaded rod 8, the bottom surface of the nut 10 is fixedly connected to two support columns 11, the bottom ends of the two support columns 11 are fixedly connected to a base plate 12, and a universal wheel 13 is provided on the bottom surface of the base plate 12, the side walls of the four nuts 10 are fixedly connected to a limit plate 14, the bottom surface of the support seat 2 is fixedly connected to four limit rods 15, and the four limit plates 14 are respectively slidably sleeved on the four limit rods 15 to ensure that the nut 10 and the threaded rod 8 can be threadedly engaged, and the four telescopic moving components are respectively located at the four corners inside the support seat 2, so that the running-in experimental table body 1 has good stability when moving.

[0028] The detailed working process of this utility model is as follows:

[0029] Before use, when the running-in test bench body 1 needs to be moved, the first rotating shaft 3 is rotated by turning the handle, thereby driving the synchronous wheel 5 on the first rotating shaft 3 to rotate, and the other two synchronous wheels 5 and the second rotating shaft 4 are driven by the synchronous belt 6 to rotate, thereby driving multiple telescopic moving components, so that the running-in test bench body 1 has convenient mobility;

[0030] Here we take a telescopic moving component as an example. The four components operate synchronously. The No. 2 rotating shaft 4 rotates, which in turn drives the worm 7 to rotate, thereby driving the worm wheel 9 and the threaded rod 8 to rotate through the meshing transmission. The threaded rod 8 rotates, and under the restriction of the limit plate 14 and the limit rod 15, the nut 10 engages with the threaded rod 8, and then moves up and down along the threaded rod 8. When the running-in test bench body 1 needs to move, the nut 10 moves downward, and drives the bottom plate 12 and the universal wheel 13 to move downward through the two support columns 11. The universal wheel 13 gradually contacts the ground and supports the support seat 2. At this time, the running-in test bench body 1 has convenient movement capability. After the movement is completed, the No. 1 rotating shaft 3 is reversed. Similarly, the nut 10 will move upward, thereby causing multiple universal wheels 13 to retract into the support seat 2, so that the support seat 2 contacts the ground again, so that the running-in test bench body 1 still has good stability, thereby ensuring the stable progress of subsequent tests.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
