Abstract

The invention discloses a vehicle and a shifting impact reduction device thereof. The shifting impact reduction device comprises a first hydraulic oil pipe, a flow controller, a second hydraulic oil pipe, a first check valve, an oil supply pipeline, and an oil drainage pipeline, wherein the first hydraulic oil pipe is used for charging or draining oil for a clutch; the flow controller is arranged at the first hydraulic oil pipe; the two ends of the second hydraulic oil pipe are respectively connected with the first hydraulic oil pipe; the two connecting positions of the first hydraulic oil pipe and the second hydraulic oil pipe are respectively positioned on the two sides of the flow controller; the first check valve is arranged at the second hydraulic oil pipe; when the hydraulic oil in the second hydraulic oil pipe flows towards the clutch direction, the first check valve is turned on; the oil supply pipeline is connected with the first hydraulic oil pipe through a first valve device; the oil drainage pipeline is connected with the first hydraulic oil pipe through a second valve device. Through the arrangement, the shifting impact reduction device provided by the invention can solve the problems that the mechanical structure is complicated and the occupied space is large due to adoption of an energy accumulator under the condition of reducing shifting impact.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle and a gear shifting impact reduction device thereof. Background technique [0002] When the vehicle clutch is engaged, the hydraulic system charges the clutch with oil, and when the clutch is disengaged, the hydraulic system controls the clutch to drain. [0003] When the vehicle is shifting gears or returning to neutral gear, the clutch needs to be filled with oil and drained. In order to enable the clutch to respond quickly, when the clutch is engaged, the hydraulic system needs to quickly fill the clutch with oil. However, when the clutch is disengaged, if the clutch oil drain process is fast, the mechanical parts of the clutch will be disengaged quickly, which will cause an impact on the parts of the clutch, thereby causing the impact of the whole vehicle. [0004] In the prior art, in order to reduce the shock caused to the parts of the clutch during the c...
