Example two
The first difference between the present embodiment and the embodiment is that the working chamber of the present embodiment is an upper oil chamber, specifically:
As shown in fig. 11-20, the piston 502 divides the cylinder 501 into an upper oil cavity 504 and a lower oil cavity 505, when the working cavity is the upper oil cavity 504, the head end of the damping branch 3 is communicated with the upper oil cavity 504, the tail end of the damping branch 3 is communicated with the oil tank 6, the piston also comprises a sixth pipeline 16 for connecting the lower oil cavity 505 and the oil tank 6, a valve is arranged on the sixth pipeline 16, a one-way valve seven 506 for flowing from the lower oil cavity 505 to the upper oil cavity 504 is arranged on the piston 502, and the volume of hydraulic oil flowing from the lower oil cavity 505 to the upper oil cavity is larger than the stroke volume of the piston 502 of the upper oil cavity 504 under the same stroke of the piston 502.
The valve is a check valve five 17 which is communicated from the oil tank 6 to the lower oil cavity 505.
The above arrangement of the present invention can ensure that when the working chamber is the upper oil chamber 504 and hydraulic oil is circulated in one direction in the upper oil chamber 504, the hydraulic oil passes through the damping branch 3 in one direction, and a smooth damping force can be ensured after passing through the throttle valve 19.
As shown in fig. 12, when the piston 502 moves downward, hydraulic oil in the lower oil chamber 505 flows into the upper oil chamber 504 through the one-way valve seven 506, meanwhile, under the same stroke of the piston 502, the volume of hydraulic oil flowing into the upper oil chamber 505 is larger than the stroke volume of the piston 502 of the upper oil chamber 504, and the hydraulic oil flowing out of the upper oil chamber 504 flows into the head end of the damping branch 3, and one or more throttle holes 402 in the plurality of throttle electromagnetic valves 4 are selected to be in a communication state according to requirements, and finally flows into the oil tank 6 from the tail end of the damping branch 3; as shown in fig. 13, when the piston 502 moves upward, hydraulic oil in the upper oil chamber 504 passes through the head end of the damping branch 3, and one or more throttle holes 402 in the plurality of throttle solenoid valves 4 are selected to be in a communication state according to requirements, and finally flow into the oil tank 6 from the tail end of the damping branch 3, and meanwhile, the lower oil chamber 505 absorbs oil from the oil tank 6 through the pipeline six 16 and the check valve five 17.
When the working oil cavity is the lower oil cavity, the connection and pipelines among the shock absorber 5, the integrated seat 18 and the oil tank 6 are relatively complex, and the valve is more, so that the integrated seat 18 is positioned below the damping vibration reduction device, the electromagnet connecting cable of the throttle solenoid valve 4 is easy to access, and a dust cover is easy to be arranged above the damping device; when the working oil cavity is the upper oil cavity, the connection and the pipeline between the shock absorber 5, the integrated seat 18 and the oil tank 6 are relatively simple, and the valve is smaller, so that the integrated seat 18 is positioned above the damping vibration reduction device, the electromagnet connection cable of the throttle solenoid valve 4 is longer, a dust cover is difficult to set above the damping device, the hydraulic damping device further comprises a base 20, and the base 20 is used for sealing the lower end of the cylinder 501 and installing a pipeline six 16 and a one-way valve five 17.
