Background
In the existing light truck, heavy truck and other vehicles, a gear shifter is divided into a manual operation and a manual operation, and is used for a driver to carry out speed change control on a gearbox of the vehicle in the driving process, and the gear shifter generally has 2 main functions, namely gear selection and gear shifting. The handle is pulled by hand, the gear shifting rod connected with the handle can drive the ball head below to rotate, so that the hard shaft below is driven to rotate and stir. The hard shaft is also provided with a supporting point of a ball head connecting rod. The supporting point has different structural designs for different vehicle types. The automobile gear shifting assembly refers to a gear shifter assembly and a hard shaft assembly which is connected with the gear shifter and a gearbox, generally, gear selection is carried out by pushing and pulling a hard shaft, and gear selection is carried out by swinging the hard shaft.
The current analog loads are generally unidirectional loads and single loads; the simulation load adopts a spring which can only bear force in one direction, namely tension or pressure, can not be loaded in two directions, and has tension and pressure output; and the actual vehicle state is selected and shifted by both pushing and pulling. The single load means that a gear selection endurance test is selected, and the simulated load is added; after the gear selection is finished and the gear selection is durable, a gear shifting endurance test is carried out, and the simulated load is added. The gear selecting and shifting endurance test cannot be carried out simultaneously due to the influence of the structure. Therefore, the shifter with the hard shaft assembly can simulate a load mechanism in a real vehicle state and is very important; only the test of gear selection and gear shifting linkage is closer to the real vehicle state, and only the test that the bidirectional stress loading is met is closer to the real vehicle state.
