Japanese pressure spring standard parts:

. Compression springs are the most common metal spring structures. Helical compression springs are the most common configuration of metal springs. These coil springs can operate independently, although they are usually mounted on a guide bar or in a hole. When you put a load on a compression coil spring to make it short, it will have resistance and try to return to its original length. Compression spring is an open coil or pressed helical spring, used to resist the axial force generated by compression, compression spring will produce resistance to linear pressure (thrust), in fact, the spring is the most efficient storage of energy.

Network optimization materials:

Absorber, the shock absorber is critical for damping the fluctuations of professional butterfly springs that bounce back after absorbing earthquakes and the impact of the absorber from the ground. Although the rip-resistant projectile can worry about the vibration of the ground, the professional torsional projectile itself will continue to have repeated motion when it passes through the rough ground, and the shock absorber is used to restrain the bounce of such projectile [1]. If the shock absorber is too soft, the car body will bounce up and down. If the shock absorber is too hard, it will produce great friction resistance, preventing the normal operation of the elastic yellow. In the whole process of modification of the suspension system, the hard shock absorber should be matched with the hard elastic yellow, and the strength of the professional butterfly elastic yellow is closely related to the weight of the car, so the heavy car generally chooses the hard shock absorber. A device connected to the crankshaft of a jolting engine to match the twisting vibration of the engine crankshaft (that is, the shaking of the engine crankshaft by the impact of the cylinder fire).

The very simple shock absorber that has been described all over the world was invented in 1897 by two men named Jimin. They put the vulcanized rubber shock block and leaf bullet yellow at the top of the connection, when the suspension system is completely reduced, the vulcanized rubber shock block is connected to a anchor bolt on the car girder, causing stop. This kind of shock absorber and many contemporary car suspension system is still applied, professional torsion spring but its actual shock absorber effect is not big.
