The advantage of fruit.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the invention.
Specific embodiment
Below with reference to accompanying drawing, the present invention is described in detail.As shown in figure 1, self-adjustable automobile hydraulic of the invention is outstanding
Put, including top end opening housing, set and be plugged in the rubber spring 2 at housing tip opening and be arranged at case inside bottom
The rubber counterdies 4 in portion, are provided with base on the rubber spring, the housing is made by every magnetic aluminum alloy materials, the base
It is made up of metal materials such as copper, iron, fluid injection steam vent is provided with base, fluid injection steam vent runs through rubber spring, rubber spring
Fixed by fluid technology between upper shell and rubber spring and base, using having the big of two kinds of functions of fluid injection and exhaust concurrently
Diameter pore structure simplifies the structure of suspension as fluid injection steam vent, and sealing property is more preferable, the also connection including being connected with engine
Bar 3, the connecting rod upper end is fixedly connected by the center screw thread of base with base, and the housing includes what is be bolted
Upper shell 101 and lower house 102, form closed and full of the chamber of ethylene glycol liquid between the rubber spring and rubber counterdies
Room, is provided with the dividing plate 6 that chamber is divided into upper chamber body 501 and lower chamber body 502 in the chamber, the dividing plate middle part is provided with out
Mouth groove 7, the open slot is connected by inertia channel 8 with lower chamber body, and the work being slidably socketed with open slot is provided with open slot
Dynamic plate 9, the portable plate is connected by spring 10 with opening trench bottom, forms circumferential between portable plate edge and opening groove sidewall
Damp channel 11, forms the radial direction damp channel 12 connected with circumferential damp channel between portable plate bottom and opening trench bottom.
The self-adjustable automobile hydraulic suspension of the structure, when vehicle is in Acceleration of starting, shifts gears or run into road shocks operating mode, low frequency is big
Amplitude vibration occurs, and the distance that portable plate is moved down is bigger, and radial direction damp channel width is narrower, so as to provide larger damping
Power, suspension show the big damping characteristic of big rigidity, can effective attenuation vibration, suppress engine displacement, when vehicle be in idling or
