Problems solved by technology

However, large-displacement motorcycles have large engine power, high speed, and heavy body. The disadvantages of the three-barrel formal structure are gradually emerging. It only has a fixed damping force at a fixed speed, and cannot adapt to the driving requirements of different roads and different loads. At higher driving speeds, the shock absorber's response to the road's shock absorption is delayed, resulting in insufficient grip of the tires and accidents

Abstract

The invention relates to the technical field of shock absorbers, in particular to an aluminum alloy double-adjustment inflatable inverted front shock absorber. The aluminum alloy double-adjustment inflatable inverted front shock absorber comprises an aluminum barrel assembly, a front fork pipe assembly, a working cylinder assembly, a piston rod assembly, a circulating valve assembly, a recovery adjusting valve assembly, an inflation bottle assembly and a compression adjusting valve assembly, wherein the aluminum cylinder assembly is provided with a first cavity along the axis; and one end of the front fork pipe assembly extends into the first cavity from one end of the first cavity. According to the aluminum alloy double-adjustment inflatable inverted front shock absorber provided by the invention, the front shock absorber is more sensitive to the road surface and high in structural strength, compared with a common inverted front shock absorber in low-speed running and high-speed running, shock of a vehicle body can be well reduced, the road holding force of tires in the running process of a locomotive is enhanced, side slip is prevented, and the safety and comfort of high and lowspeed riding of two-wheeled motorcycles and electric vehicles are guaranteed.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to an aluminum alloy double-adjustable inflatable inverted front shock absorber. Background technique [0002] The shock absorber is a device composed of a hydraulic damper and a spring, which is used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface, so as to improve the ride comfort (comfort) of the vehicle. Today's small-displacement motorcycle front shock absorbers usually have a three-tube formal structure, which is mainly composed of aluminum tubes, front fork tubes, positioning tubes and shock absorbing springs, and has the advantages of simple structure and low cost. However, large-displacement motorcycles have large engine power, high speed, and heavy body. The disadvantages of the three-barrel formal structure are gradually emerging. It only has a fixed damping force at a fixed speed, and cannot adapt to t...
