Shock-absorbers on design are divided into two main types: two-pipe and one-pipe shock-absorbers.
1. Atmospheric pressure.
2. The valve regulating resistance to compression.
3. The valve regulating resistance to stretching.
4. Perepusknye of the valve.
1. Atmospheric pressure.
2. Reserve camera.
3. Basic odnotrubna system.
Damper – the additional weight which provides elasticity and muffles fluctuations of the vehicle. The damper assimilates fluctuations of the main system, that is, the main system stops vibrating – the movement is limited to the vibration absorber. Dampers minimize the movements of the case. As a damping element it can be used; as liquid – (oil shock-absorbers), and gas (gas shock-absorbers).
The one-pipe shock-absorber is characterized by high degree of reliability, low sensitivity to overloads, noncriticality to the provision of installation. It is necessary to refer to shortcomings dependence of extent of clearing on compression parameters (which in the last developments compensate by installation of additional perepuskny valves in the piston) and the fact that the one-pipe shock-absorber is the shock-absorber of long type.
The two-pipe shock-absorber is technologically known as the atmospheric, working with a low pressure type of a double pipe.
Advantages: insensitive to external damages. Here, unlike the one-pipe shock-absorber, mechanical influences can be accepted also by an external pipe, the verified position of the machine is limited to area of a design of a body. It is short type of the shock-absorber as the camera of balance is located behind the working cylinder.
Shortcomings: the shock-absorber is sensitive to an overload (damping stops). Only certain provisions of installation, precision accuracy of coordination of diameters of pipes are possible.
Characteristics of damping are result of total function of damping of an opening and the valve loaded by a spring which closes the channel; the spring answers pressure, increasing a free aperture of an opening of an exit. The opening of the piston and a spring can specially adapt to provide linearity and softness of function of clearing. The internal mechanism of regulation is used to receive several performance data for the separate shock-absorber. Values of extent of compression – only 30 is frequent... 50% of ability of return.
Shock-absorbers with the electronic and adjustable characteristic (active completion) are used to expand the range of comfort of the movement and to increase safety. Management of damping parameters, on the other hand, leads to establishment of communication between comfort and safety.
