Benefits of technology

The technical feature described in this patented technology allows for more efficient use of space while preventing too much or insignificant energy from being transferred between two parts that move relative to each other during movement. This improves how well an impact-absorbing device works effectively without overloading its components.

Problems solved by technology

This technical problem addressed in this patented describes two types of conventional bumper shockabsorbers (BSA). One type uses a single-piece or double-section design, which allows fluid communication between different chambers within one component called the main body. Another type utilizes multiple components separated by partitions to allow more flexibility during operation. However both these designs have their own drawbacks such as limited adjustment range caused by the size of the reservoir and slower response compared to other methods like liquid spring systems.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 2 As shown, an automobile cylinder type hydraulic shock absorber of the present invention comprises an axially vertical hydraulic cylinder block 1, and a partition plate is arranged in the hydraulic cylinder block 1 to divide the interior of the hydraulic cylinder block 1 into upper and lower sections. The interior of the hydraulic cylinder 1 above the plate is used as a working chamber filled with hydraulic oil, and the interior of the hydraulic cylinder 1 below the partition is used as a pressure relief compensation chamber 8 .

[0022] The first piston 2 is vertically slid in the working chamber. The first piston divides the working chamber into the lower part A of the working chamber and the upper part B of the working chamber. Body, the bottom of the hydraulic cylinder block 1 is connected to the automobile suspension. The fir

Abstract

The invention discloses a barrel type hydraulic shock absorber of an automobile. The barrel type hydraulic shock absorber comprises a vertical hydraulic cylinder body, a partition plate is arranged in the hydraulic cylinder body, a working cavity is formed above the partition plate and filled with hydraulic oil, a pressure relief compensation cavity is formed below the partition plate, a first piston is vertically assembled in the working cavity in a sliding mode, and a circulation valve and a rebound valve are installed on the first piston. The partition plate is provided with a compression valve and a compensation valve, a second piston is vertically assembled in the pressure relief compensation cavity in a sliding mode, and a spring is connected between the second piston and the inner bottom of the pressure relief compensation cavity. The problem that damping attenuation of the shock absorber is too fast can be avoided, and meanwhile the damping recovery speed can be increased.
