Specific embodiment
As Figure 1-Figure 4, a kind of fixed car damping device, including including lower connecting block 10, the lower connecting block
Lower lifting lug 11, the affixed outer cylinder 13 in the top of the lower connecting block 10,13 inner vertical of the outer cylinder setting oil is arranged in 10 bottom
Cylinder 1, is step-like structure at the top of the oil cylinder 1, and hollow piston rod 2, the piston rod 2 is arranged in 1 inner vertical of oil cylinder
The affixed piston 4 on the side of bottom, the bottom surface of the piston 4 is flushed with the bottom surface of the piston rod 2, on the piston 4
Through at least one damping hole 5 of setting;Vertical piston interior bar 3,3 top of piston interior bar are set inside the piston rod 2
Higher than 2 top of piston rod, bottom surface is flushed with 2 bottom surface of piston rod, 3 outer wall of piston interior bar and the piston rod 2
Interior wall seamless connect, the affixed baffle 6 in 3 bottom surface of piston interior bar;Sealing cover 7 is set on the step-like structure of the oil cylinder 1,
The top of the piston rod 2 passes through the sealing cover 7, and affixed upper link block 8, the top surface of the piston rod 2 and the upper company
It connects 8 top surface of block to flush, upper lifting lug 12 is set on the side of the upper link block 8;The top of the piston interior bar 3 passes through on described
Link block 8 and affixed handle 9, the bottom surface of the handle 9 are contacted with the top surface of the upper link block 8;It is arranged outside the outer cylinder 13
Spring 14, the affixed upper link block 8 in 14 upper end of spring, the affixed lower connecting block 10 in lower end.
In the installation of damper and in use, the outer cylinder 13 shields to the oil cylinder 1.
When mounting shock absorber, the sealing cover 7 is mounted on the step of the oil cylinder 1, in the sealing cover 7 and described
Hydraulic oil is filled in the oil pocket that oil cylinder 1 is encircled a city.The upper lifting lug 12 is mounted on vehicle frame, the lower lifting lug 11 is mounted on vehicle bridge
