Description
Technical field
The invention belongs to vehicle shock absorber technical fields, are specifically 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, preferable effectiveness in vibration suppression is not achieved
And control stability.
The content of the invention
For the present invention in view of the shortcomings of the prior art, providing vehicle shock absorber, this kind of vehicle shock absorber can adjust damping, so as to
So that vehicle preferably adapts to different road surfaces, the comfort of vehicle, handling and security are improved.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：Vehicle shock absorber, including solid
Reservation, sliding seat, working cylinder, slide bar and spring are provided with several working cylinders in the fixed seat, in each working cylinder
Inserted with slide bar, the slide bar end set in the working cylinder has the section of piston, the working cylinder and the piston
It is non-circular, damping hole is provided on the piston, the slide bar end set outside the working cylinder has external screw thread, described
Several slide bar one-to-one corresponding, which are provided with middle part, on sliding seat has the rotating bar of slideway, and the cross section of slideway is not rounded
Shape is provided with middle part matched with the slideway in the slideway and has female sliding sleeve, the external screw thread and the interior spiral shell
Line coordinates, and the slideway height is identical, and motor is provided on the sliding seat, the first tooth is provided on the motor output shaft
It takes turns, second gear is both provided in the rotating bar, the first gear is engaged with the second gear, each second tooth
It takes turns different from the gearratio of first gear engagement.This kind of vehicle shock absorber can be driven when in use by the rotation of motor
Rotating bar rotates, and position on slide bar is slided over by internal thread and externally threaded cooperation during rotating bar rotates
Change, since each second gear is different from the gearratio that the first gear engages, shake so that some are slided over
Upper end abuts against the end face of slideway in dynamic process, some can be free to slide in slideway during sliding over vibration, also has
Some slide over vibration during lower face abut against slideway end face and some slide over vibration during originally freely
End face then with slideway is slided to abut against, rotated by motor change can in sliding sleeve quantity free to slide in slideway and
The Oscillation Amplitude that sliding sleeve is abutted against with end face, so as to adjust the damping force of sliding bar, so that vehicle preferably adapts to difference
The comfort of vehicle, handling and security are improved in road surface.
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 to rotate, and passes through internal thread and externally threaded cooperation sliding sleeve during rotating bar rotates
Position on slide bar changes, since each second gear is different from the gearratio that the first gear engages, so that
Some slide over vibration during upper end abut against the end face of slideway, some can be in slideway during sliding over vibration
It is free to slide, also have some slide over vibration during lower face abut against slideway end face and some slide over vibration
The end face originally free to slide then with slideway abuts against in the process, and rotating change by motor can be free to slide in slideway
Sliding sleeve quantity and the Oscillation Amplitude that abuts against of sliding sleeve and end face, so as to adjust the damping force of sliding bar, so that vehicle
Different road surfaces are preferably adapted to, improve the comfort of vehicle, handling and security.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the embodiment of the present invention.
Fig. 2 is the partial enlarged view of Fig. 1.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 2, automobile
