Abstract
The utility model discloses a split-type shock absorber with adjustable damping, which comprises a shock absorber body, an external foot valve and an oil circuit passage; the shock absorber body is communicated with the external foot valve through the oil circuit passage; and an electronic control valve is arranged on the oil circuit passage. Different open states of the electronic control valve can be selected according to different road conditions and driving conditions; the flow rate of damping oil passing through the oil circuit passage is controlled to change the damping characteristic of the shock absorber; during normal driving in cities, the damping of the shock absorber can be reduced, so that the driving is more reposeful; and when the road is uneven, the damping of the shock absorber can be increased to buffer the shock of the road, thereby improving the driving comfort.
Description
Technical field
The utility model relates to a kind of vibration damper, particularly a kind of damping adjustable split type vibration damper.
Background technique
Vibration damper is mainly used in field of vehicles and absorbs and alleviate that wheel contacts with road in driving, is delivered to the swing or the vibrations of vehicle body.
Vibration damper commonly used is when design, no matter be hydraulic damping or spring damping, in case after selected, damping characteristic just determines, this structure can be in the travelling comfort of certain vibrations scope with the interior assurance traffic tool, but the adaptability of this structure is limited, in case pavement behavior exceeds scope of design, the effect of vibration damper will be had a greatly reduced quality so, influences the travelling comfort of the traffic tool.
In order further to improve the ride quality and the operational stability of the traffic tool, according to road conditions, vehicle driving state etc. correspondingly carries out suitable adjustment to the vibration damper damping, in the prior art, China Patent No. is 200720038009.7 to disclose the multistage damping shock absorption device of a kind of split type adjustable gas chamber pressure, its structure is that the piston rod of vibration damper body is a hollow-core construction, and spool is set in piston rod, and the through hole that is provided with on spool and the piston rod forms radially adjustable orifice.This structure more complicated, and be to regulate by adjusting knob to the adjusting of spool, be unfavorable for the automatic control that damping is regulated.
Therefore, need a kind of damping adjustable split type vibration damper, can control by circuit, make the driver can regulate the damping of vibration damper at any time according to the road surface situation, vibration damper all has damping performance preferably under different road surface situations, guarantee that the traffic tool have good comfort level always, and simple in structure, easy for installation.
The model utility content
In view of this, the utility model provides a kind of damping adjustable split type vibration damper, can control by circuit, make the driver can regulate the damping of vibration damper at any time according to the road surface situation, vibration damper all has damping performance preferably under different road surface situations, guarantee that the traffic tool have good comfort level always, and simple in structure, easy for installation.
Damping adjustable split type vibration damper of the present utility model comprises vibration damper body, external bottom valve and asphalt channel, and described vibration damper body and external bottom valve are communicated with by asphalt channel, and described asphalt channel is provided with electric control valve.
Further, described vibration damper body comprises active chamber, is arranged on piston and the piston rod that is connected with piston in the active chamber;
Further, be provided with floating piston in the described external bottom valve, floating piston is divided into oil pocket and air cavity with external bottom valve, and oil pocket is connected with the vibration damper body by asphalt channel, compressed air suits in the air cavity;
Further, described asphalt channel is a hose construction, and the joint of asphalt channel end and vibration damper body or external bottom valve is provided with electric control valve.
The beneficial effects of the utility model: according to different road surface situations and driving situation, select the different opening state of electric control valve, the damping oil flow that passes through in the asphalt channel is controlled, to change the damping characteristic of vibration damper, when cruising in the city, reduce the damping of vibration damper, make driving more steady; When running into when jolting the road surface, increase the damping of vibration damper, the buffering road shocks improves the comfort level of driving.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion partial enlarged drawing of Fig. 1.
Embodiment
