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...

The invention discloses an engineering vehicle shifting device with a buffering mechanism. The engineering vehicle shifting device comprises a valve body, wherein an oil inlet and an oil outlet are formed in the valve body, a communicating channel is arranged between the oil inlet and the oil outlet, and one end of the communicating channel penetrates through the outer surface of the valve body; a piston rod is arranged in the communicating channel, the piston rod is provided with an oil passing channel capable of enabling the oil inlet or the oil outlet to communicate, a control rod is arranged on the piston rod, and the diameter of the control rod is smaller than that of the piston rod; a control cover is arranged on the outer surface of the valve body, and a blind hole is formed in the control cover; and the control rod is sleeved with a control spring, one end of the control spring abuts against the end face of the piston rod, the other end of the control spring abuts against the bottom face of the blind hole, and a micro-channel communicating with the two ends of the oil inlet is formed in the piston rod. Due to the fact that the shifting mechanism is provided with the buffering mechanism, the service life of a power transmission mechanism part of an engineering vehicle can be prolonged, and the driving comfort and controllability of the engineering vehicle are improved.
Description
technical field [0001] The present invention relates to a buffer mechanism, more specifically, the present invention relates to a buffer mechanism used in a shifting device of an engineering vehicle. Background technique [0002] Engineering vehicles need to switch between forward and backward frequently during work. The engineering vehicles in the prior art have the following defects when switching between forward and backward. The vehicle shakes violently and emits a large impact noise. These two defects Seriously affect the service life of the power transmission mechanism of the engineering vehicle and the driving comfort and controllability of the driver of the engineering vehicle. Contents of the invention [0003] In order to overcome the above-mentioned defects, the technical problem to be solved by the present invention is to provide a buffer mechanism of a shifting device that can prolong the service life of the power transmission mechanism of the engineering vehi...
