Detailed Description

The attached figure 1 of the specification is as follows: the guide seat assembly 6 and the outer cylinder barrel assembly 1 are connected together by threads.

The attached figure 1 of the specification is as follows: the inner cylinder 4 axially connects and fixes the guide holder assembly 6 and the discharge valve assembly.

The attached figure 1 of the specification is as follows: the piston assembly 3 and the piston rod 7 are connected together by screw threads.

The attached figure 1 of the specification is as follows: the dust cover assembly 5 and the connecting ring 8 are connected together by welding.

The attached figure 1 of the specification is as follows: the spherical plain bearing 10 is positioned in the inner bore of the connection ring 8, and the retainer ring 9 positions the spherical plain bearing 10 on the connection ring 8 in the axial direction.

The attached figure 1 of the specification is as follows: a rod chamber 11 is formed in the cavity between the piston assembly 3, the guide shoe assembly 6, the piston rod 7 and the inner cylinder 4.

The attached figure 1 of the specification is as follows: the hollow spaces between the discharge valve assembly 2, the piston assembly 3 and the inner cylinder 4 form a rodless chamber 13.

The attached figure 1 of the specification is as follows: the cavity between the outer cylinder barrel assembly 1, the guide seat assembly 6 and the inner cylinder barrel 4 forms an oil storage cavity 12.

The specification is as follows in figure 2: the guide seat assembly 6 consists of a guide seat 61, a sliding bearing 62, a piston rod sealing ring 63, a dustproof ring 64 and an O-shaped ring 65

The accompanying 3 and 4 of the specification show: the guide holder 61 is provided with a guide holder conical surface 611, a guide holder inclined hole 612, and an inner groove 613, and the guide holder inclined hole 612 communicates the inner groove 613 with the guide holder conical surface 611.

The working process of the hydraulic shock absorber with the guide sleeve provided with the inclined hole is as follows: when a piston rod of a hydraulic shock absorber with a guide sleeve provided with inclined holes is pulled by external force, a piston assembly moves towards a rod cavity, a compression valve core is closed, oil in the rod cavity pushes away a recovery valve core, so that the oil enters a rodless cavity, the volume of the rod cavity is smaller than that of the rodless cavity in the same stroke, the oil flowing out from a rod of the rod cavity is not enough to fill the space of the rodless cavity, a true degree can be formed in the rodless cavity, the pressure of the oil in an oil storage cavity pushes away a compensation spring piece, so that the oil in the oil storage cavity enters the rodless cavity, when the piston rod is pressurized, the piston assembly in the shock absorber moves towards the rodless cavity, the volume of the rodless cavity is reduced, the oil pushes away the compression valve core, the recovery valve core is closed, the oil enters the rod cavity, and a part of the oil pushes away a discharge valve of the discharge valve assembly, so that the oil flows back to the oil storage oil cylinder 4 to input pressure oil. The hydraulic shock absorber with the inclined hole in the guide sleeve has the shock absorption effect due to the opening of the valve and the arrangement of the damping hole in the stretching and compressing processes of the piston. The hydraulic shock absorber with the guide sleeve provided with the inclined hole is reasonable in design, compact in structure and stable in performance. The vibration absorber is widely applied to vibration reduction of automobile wheels.
