Description
Technical field
The invention belongs to vehicle suspension system technical field, more particularly to a kind of shock absorber, vehicle suspension and vehicle.
Background technology
Shock absorber is important part in vehicle suspension system, plays buffering road shocks, decay suspension and vehicle body vibrations
Effect, directly affects the handling and comfortableness of vehicle.The performance of shock absorber can pass through F-V curves (damping force-speed
Curve) specifically quantify.
Generally, the damping force effect of shock absorber is mainly reflected in the damping force (resistance brought by piston that bottom valve is brought
Buddhist nun's power can be ignored), and when considering the damping force of shock absorber, generally only consider damping force during compression travel, thus, vibration damping
The usual damping force by the bottom valve of shock absorber in compression travel of the performance of device changes to describe.
The structure that existing shock absorber is used is substantially dual-tube shock absorber.As shown in figure 1, being a kind of existing bitubular vibration damping
Device, in the dual-tube shock absorber, the damping force in compression travel is main by unique bottom valve assembly 1a in cylinder bottom portion is Lai real
Existing (F-V curve of the produced F-V curves close to shock absorbers compression stroke in bottom valve compression travel), such structures shape
Bottom valve is in the piston 2a high speeds of shock absorber or the tribute of low-speed motion (it has been generally acknowledged that piston movement speed is low speed less than 0.1m/s) institute
The damping force offered reaches unanimity；That is, (dotted line and solid line respectively represent a kind of bottom valve of shock absorber in compressed line in figure as shown in Figure 2
F-V curves during journey), it can be seen that the damping force low speed of the bottom valve of the shock absorber represented by solid line is big, also big (i.e. high at a high speed
Damping force when fast is not gentle), the damping force low speed of the bottom valve of the shock absorber represented by dotted line is small, at a high speed also it is small (i.e. high speed when
Damping force tend towards stability).The big high speed of damping force low speed of shock absorber also big vehicle, its handling is good, but ride comfort
Property is poor；The small high speed of damping force low speed of shock absorber also small vehicle, its riding comfort is good, but handling is poor.
