Description
Technical field
The invention belongs to vehicle shock absorber technical field, specifically a kind of vehicle shock absorber.
Background technology
Vehicle shock absorber operation principle is to work as vehicle frame to make reciprocal relative movement with vehicle bridge, and piston moves back and forth in cylinder barrel
When, fluid in damper hole narrow on by valve back and forth flows between two mutually isolated inner cavities, due to hole wall with
The interior friction of friction and fluid molecule between fluid forms damping force, so as to which the mechanical energy of body vibrations is converted into thermal energy quilt
Fluid and housing absorb, and then spill into air.Damping force is with passing through the sectional area of oil passage, valve spring rigidity and fluid
Viscosity is related.
Currently, passive suspension generally use is common double-cylinder hydraulic damper, since its damping is non-adjustable, so cannot
The damping characteristic of suspension system is adjusted according to road conditions, running conditions of vehicle or loading capacity, ideal effectiveness in vibration suppression is not achieved
And control stability.

It closes.This kind of vehicle shock absorber can drive rotating bar to rotate by the rotation of motor when in use, in the process of rotating bar rotation
In position change on slide bar slided over by internal thread and externally threaded cooperation so that some slide over vibration
Upper end abuts against the end face of slideway in the process, some can be free to slide in slideway during sliding over vibration, more also
Slide over vibration during lower face abut against slideway end face and some slide over vibration during it is originally free to slide
It is then abutted against with the end face of slideway, being changed by motor rotation can be in sliding sleeve quantity and sliding sleeve free to slide in slideway
The Oscillation Amplitude abutted against with end face, so as to adjust the damping force of sliding bar, so that vehicle preferably adapts to different road surfaces,
Improve the comfort of vehicle, handling and safety.
In above-mentioned technical proposal, it is preferred that be provided with bearing between the rotating bar and the sliding seat.Using the structure
So that the rotation between rotating bar and sliding seat is more smooth.
In above-mentioned technical proposal, it is preferred that one end in the rotating bar close to the sliding seat is provided with first exhaust
Hole is provided with the second row stomata connected with the first row stomata on the sliding seat.To slide over not using the structure
It is slided when being contacted with slideway end more smooth.
Compared with prior art, the present invention it has the advantages that：This kind of vehicle shock absorber can pass through when in use
The rotation of motor drives rotating bar rotation, passes through internal thread and externally threaded cooperation sliding sleeve during rotating bar rotates
Position change on slide bar, so that some slide over the end face that upper end during vibrating abuts against slideway, some sliding sleeves
Can be free to slide in slideway during vibration, lower face abuts against slideway during more also sliding over vibration
End face and some slide over vibration during it is originally free to slide then abutted against with the end face of slideway, rotated by motor
Change the Oscillation Amplitude that can be abutted against in sliding sleeve quantity and sliding sleeve free to slide in slideway and end face, so as to adjust slide bar
The damping force of slip so that vehicle preferably adapts to different road surfaces, improves the comfort of vehicle, handling and safety.
