Automotive energy feedback type shock absorber

Abstract

The invention provides an energy feedback type shock absorber, and relates to the technical field of automotive parts. The inner wall of a cylinder body is in clearance fit with the radial surface ofa piston body, a piston rod is arranged on the lower end face of the piston body, and the piston rod penetrates through a through hole formed in the center of a lower cover plate to be fixed to a lower hanging ring; a pair of bearing pedestals are perpendicularly arranged on the bottom face of an upper cover plate, one end and the middle of a main shaft are fixed to the bearing pedestals through deep groove ball bearings separately, and the other end of the main shaft penetrates through the side wall of the cylinder body and is connected with an input shaft of an electric generator through a coupler; inner rings of a first overrun clutch and a second overrun clutch are matched with each other through a key in parallel and fixed to the main shaft, an outer ring of the first overrun clutch is fixed to one end of a first horizontal connecting rod, and an outer ring of the second overrun clutch is fixed to one end of a second horizontal connecting rod; and the lower portion of a first lower connecting rod and the lower portion of a second lower connecting rod are each sleeved with a spring, and the upper ends and the lower ends of the springs make contact with the lower surface of an intermediate plate and the upper end face of the piston body.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a structure of a shock absorber. Background technique [0002] With the development of the economy in recent years, my country has become the second largest country in the world in terms of car ownership. As of 2018, the number of cars is about 190 million. The amount of petroleum consumed by traditional automobiles accounts for about 1 / 3 of the total petroleum consumption every year, and automobile emissions have caused serious harm to air quality. In this context, my country vigorously advocates the development of new energy vehicles. In recent years, under the background of a series of preferential policies such as government financial subsidies and restrictions on purchasing and driving in first-tier cities that have pushed up the cost of holding traditional car licenses, new energy vehicles have ushered in rapid growth. It is expected that the sales of new energy vehicle...

Problems solved by technology

[0005] Among the above-mentioned two technical schemes of the device utilizing automobile shock absorbers to generate electricity, the first technical scheme has the following deficiencies: 1. The hydraulic circuit is adopted, and the structure is complicated, the volume is large, the weight is heavy, and the failure rate is high

The transmission chain is too long, the transmission efficiency is not high

2. Multiple shock absorbing components are arranged side by side, making it inconvenient to connect the upper end of the shock absorbing component to the suspension of the car

For the second technical solution, there are the following deficiencies: one, a group of gear trains is used, which causes the diameter of the working cylinder of the shock absorber to be too large, the structure is complicated, and the energy is transmitted through multiple stages, resulting in too low energy conversion efficiency

2. The price of the ball screw is too expensive, and the cost of gear processing is too high, which leads to the high cost of the scheme, which is not conducive to the large-scale application of the scheme
