The spring has the characteristics of extensibility and compression, it can absorb and release the bounce when the vehicle passes through the uneven road surface, reduce the bounce range of the vehicle, and make the wheel keep contact with the road surface as much as possible. The energy produced during the stretching process is converted into heat by the shock absorber and diffused into the air.
The basic introduction of progressive springs the original car models usually use progressive springs, which are of a different thickness and density, the advantage is that it can absorb the fluctuation of the road surface through the part with lower elastic coefficient when the pressure is not big, and ensure the comfortable feeling of riding. When the pressure increases to a certain extent, the spring of the thicker part can play the role of supporting the car body, but this kind of spring`s shortcoming is the control feeling is not direct, the accuracy is poor. The basic introduction of linear spring the thickness and density of linear spring from top to bottom are invariable and the elastic coefficient is fixed. This kind of spring can make the vehicle get more stable and linear dynamic response, which is helpful for the driver to control the vehicle better. It is often used in performance-oriented modified vehicles and competitive vehicles. In other cars and cars, a smaller, softer secondary spring is added to the harder linear spring, which in addition to increasing comfort reduces the force of the spring when the main spring is pressed back, prevent the main spring from disengaging from the spring seat. Short spring introduction short spring is shorter than the original spring, and more robust, the installation of short spring, can effectively reduce the body center of gravity, reduce the roll when cornering, making cornering more stable and smooth, improve vehicle cornering handling. The damping setting of the original shock absorber is biased towards comfort, so the short spring and the original shock absorber are not very stable in coordination. It can not effectively restrain the rebound and compression of the short spring. When driving on a bumpy road, there will be an uncomfortable feeling of jumping, in the long run, the life of shock absorbers will be greatly reduced, and there is the possibility of oil leakage. Of course, these conditions are relatively speaking, the day-to-day driving would not have such serious damage, and try not to drive hard, after all, the original shock absorber can not withstand high load pressure. Replacing the short spring is the most economical way to reduce the height of the car body. It is a good choice for those who do not have a large budget. Of course, a price is a good price. The short spring has very limited improvement in handling performance, and there are still many disadvantages, so in the purchase must be clear about their purpose, or when the installation will not achieve the desired effect, resulting in unnecessary waste on the tragic.

Butterfly spring overload protection for jaw crusher
Butterfly spring overload protection for jaw crusher
Longitudinally connected to the high-strength mill developed in the early days, the slewing trolley and the slewing reducer are in contact with the end face. The end faces are pinned and bolted longitudinally. This type of connection is simple in structure, reliable in connection, and the bolt only withstands tension.
Lateral connection, some rare earth mine dryer rotary car and rotary reducer side contact. With horizontal Bolts, the bolts withstand shear forces. In order to improve the state of the bolts, the Zhengzhou Hammer Crusher is connected in the form of lateral tangential keys and bolts, which is a good form of connection.
Anti-fall braking device is a broken chain protection device. When a chain break occurs, it can brake the drive shaft of the slewing car in time to prevent the slewing car from falling and avoid accidents. Anti-fall braking devices are essential safety devices on drilling rigs. The anti-dropping braking device of magnetic separator manufacturers adopts a pair of normally-closed belt brake structures. The rock drill has large torque, high impact frequency, compact structure, and precise matching of internal parts.
