Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Specific implementations of the utility model are described in detail below in connection with specific embodiments.
As shown in fig. 1, the multifunctional nitrogen shock absorber of a longitudinal nitrogen cylinder provided by an embodiment of the utility model comprises an oil storage cylinder 7, wherein an upper connecting seat 2 is arranged at the top of the oil storage cylinder 7, a piston rod 11 is arranged at the lower end of the oil storage cylinder 7, the piston rod 11 is inserted into the oil storage cylinder 7 and is connected with a piston valve system 8 arranged in the oil storage cylinder 7, one side of the upper connecting seat 2 is provided with a nitrogen cylinder 5, a floating piston 6 for separating shock absorber oil from high-purity nitrogen is arranged in the nitrogen cylinder 5, a high-speed regulating valve 4 and a low-speed regulating valve 3 are also arranged on the upper connecting seat 2, and a plurality of oil through holes are arranged in the upper connecting seat 2, so that the interior of the oil storage cylinder 7 is respectively communicated with the high-speed regulating valve 4 and the low-speed regulating valve 3 and finally communicated with the nitrogen cylinder 5;
The bottom of the piston rod 11 is provided with a lower connecting seat 14, and the lower connecting seat 14 is also provided with a rebound adjusting valve 13.
In the embodiment of the utility model, when the device is in a compression working condition, the piston valve system 8 moves forwards (namely, near one side of the upper connecting seat 2), and part of oil in the oil storage cylinder 7 passes through the high-speed regulating valve 4 and the low-speed regulating valve 3 from an oil path in the upper connecting seat 2 and finally enters the nitrogen cylinder 5. At the same time, the floating piston 6 moves backward, compressing the nitrogen. When the device is in a recovery working condition, the piston valve system 8 moves backwards, the high-pressure nitrogen pushes the floating piston 6 to move forwards, so that oil is pushed to flow into the oil passing hole, and then the oil passes through the high-speed regulating valve 4 and the low-speed regulating valve 3 and enters the oil storage cylinder 7 again. A portion of the oil in the reservoir 7 passes through the rebound adjustment valve 13 and is allowed to pass from the rear of the piston valve train 8 to the front of the piston valve train 8. Therefore, the flow rate of the oil in the oil reservoir 7 flowing through the high speed adjusting valve 4 and the low speed adjusting valve 3 in the compression condition can be controlled by adjusting the high speed adjusting valve 4 and the low speed adjusting valve 3, thereby controlling the compression damping force. Similarly, by adjusting the rebound adjusting valve 13, the flow rate of the oil flowing through the piston valve train 8 under the recovery condition can be controlled, thereby controlling the rebound damping force.
As shown in fig. 1, as a preferred embodiment of the present utility model, a limiting gasket 9 for limiting a piston rod 11 is disposed at the bottom of the oil storage barrel 7, and a sealing assembly 10 is further disposed at the bottom of the oil storage barrel 7, so as to isolate and seal the inside and the outside of the oil storage barrel 7.
As shown in fig. 1, as a preferred embodiment of the present utility model, the upper connecting seat 2 is provided with an upper rubber bushing 1, and the lower connecting seat 14 is provided with a lower rubber bushing 15.
In the embodiment of the present utility model, the upper and lower connection seats 2 and 14 are connected to the related components through the upper and lower rubber bushings 1 and 15, respectively.
As shown in fig. 1, as a preferred embodiment of the present utility model, a buffer block 12 is connected between the lower connecting seat 14 and the piston rod 11 for buffering and adjusting.
Working principle: when the device is in use, when the device is in a compression working condition, the piston valve system 8 moves forwards (namely, near one side of the upper connecting seat 2), and part of oil in the oil storage cylinder 7 passes through the high-speed regulating valve 4 and the low-speed regulating valve 3 from an oil path in the upper connecting seat 2 and finally enters the nitrogen cylinder 5. At the same time, the floating piston 6 moves backward, compressing the nitrogen. When the device is in a recovery working condition, the piston valve system 8 moves backwards, the high-pressure nitrogen pushes the floating piston 6 to move forwards, so that oil is pushed to flow into the oil passing hole, and then the oil passes through the high-speed regulating valve 4 and the low-speed regulating valve 3 and enters the oil storage cylinder 7 again. A portion of the oil in the reservoir 7 passes through the rebound adjustment valve 13 and is allowed to pass from the rear of the piston valve train 8 to the front of the piston valve train 8. Therefore, the flow rate of the oil in the oil reservoir 7 flowing through the high speed adjusting valve 4 and the low speed adjusting valve 3 in the compression condition can be controlled by adjusting the high speed adjusting valve 4 and the low speed adjusting valve 3, thereby controlling the compression damping force. Similarly, by adjusting the rebound adjusting valve 13, the flow rate of the oil flowing through the piston valve train 8 under the recovery condition can be controlled, thereby controlling the rebound damping force.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
