Embodiment
[0020]Embodiment: a shifting device of an engineering vehicle with a buffer mechanism, as shown in the figure, comprising a valve body 1 of the shifting device, the valve body 1 is provided with an oil inlet 4, an oil outlet 5 and a solenoid valve 2, The oil inlet 4 and the oil outlet 5 are arranged in parallel, and both are connected with the solenoid valve 2. In order to improve the feedback sensitivity of the buffer mechanism to the oil pressure rise, the oil inlet 4 is set close to the valve. On one side of the outer surface of the body 1, the electromagnetic valve 2 controls the on-off between the oil inlet 4 and the oil outlet 5 by pushing and pulling the spool to move the channel position set on the spool. 4. There is also a connecting channel 18 between the oil outlets 5, and the end of the connecting channel 18 that is closer to the outer surface of the valve body 1 extends outward and runs through the outer surface of the valve body 1. The connecting channel 18 The d...
