Abstract
Diversify the types of motorcycle shock absorber, and its role in the rapid attenuation of motorcycle shock is to improve the smooth running of a motorcycle, which, good or bad shock absorbers and their importance is also the embodiment of the grade of a motorcycle, a excellent shock absorber section can be improved maneuverability and stability of motorcycle, car body parts to reduce the load, extend the life of a motorcycle.
This paper introduces the present-day types of motorcycle shock absorber, it focuses on the post-shock absorber-type airbags, which make use of air inside the shock absorber of the high-pressure nitrogen-bit features to make more obvious the effect of damping, the main including tanks, piston, piston rod, upper and lower connector, shock absorber spring-oriented sets of regulators and the oil seal in the fuel tank on top and between the connector and fixed connections are airbag shell, the cavity with tanks cavity connected to pass, in the shell cavity balloon inflated with air, using high-pressure nitrogen gas inside, the fuel tank under the oil chamber to quickly stop the downward movement of the piston, both stop the rapid recovery of the shock absorber spring or shells, so that damping spring slow recovery, reducing the shock absorber of a motorcycle riding on the staff and the impact of the shock absorber damping effect so that more desirable, but also reduces the damage caused to the motorcycle.
At the same time, under the subject to the parameters of the request, access to a large number of the corresponding basis of reference to determine the shock absorber damping, including the selection of the key factors; shock absorber performance eva luation; as well as the damping Spring Design and Calculation of their airbags. Finally, through the combination of calculated and literature, focusing on the hydraulic cylinder design and calculation, and the mapping of the corresponding parts of assembly drawings and plans. The airbag is designed to shock absorber damping coefficient calculation and the choice of damping spring, hydraulic cylinder design and calculation in order to achieve better understanding of airbag-type understanding of the purpose of shock absorber.
