Description
Technical field
The utility model belongs to vehicle shock absorber technical field, 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, to convert the mechanical energy of body vibrations to thermal energy quilt
Fluid and shell absorb, and then spill into air.Damping force and pass 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 that suspension system is adjusted according to road conditions, running conditions of vehicle or loading capacity, is not achieved ideal effectiveness in vibration suppression
And control stability.
Utility model content
For the utility model in view of the shortcomings of the prior art, providing vehicle shock absorber, this kind of vehicle shock absorber can adjust damping,
So that vehicle preferably adapts to different road surfaces, the comfort of vehicle, handling and safety are improved.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：Vehicle shock absorber, packet
Fixed seat, sliding seat, working cylinder, slide bar and spring are included, several working cylinders are provided in the fixed seat, each work
Inserted with slide bar in cylinder, the slide bar end set in the working cylinder has a piston, the working cylinder and the piston
Section is non-circular, and damping hole is provided on the piston, and the slide bar end set outside the working cylinder has external screw thread,
It is non-to be arranged in a one-to-one correspondence middle part to have the rotating bar of slideway, the cross section of slideway with several slide bars on the sliding seat
Circle is provided in the slideway and has a female sliding sleeve with the matched middle part of the slideway, the external screw thread with it is described interior
Screw-thread fit, 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
Wheel is different from the transmission ratio that the first gear engages.This kind of vehicle shock absorber can be driven when in use by the rotation of motor
Rotating bar rotates, by internal thread and externally threaded cooperation so that sliding over the position on slide bar during rotating bar rotates
Change, since each second gear is different from the transmission ratio that the first gear engages, shakes 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
Some slide over vibration during lower face abut against slideway end face and some slide over vibration during originally freely
Sliding is then abutted against with the end face of slideway, by motor rotation change can in sliding sleeve quantity free to slide in slideway and
The Oscillation Amplitude that sliding sleeve is abutted against with end face, to adjust the damping force of sliding bar, so that vehicle preferably adapts to difference
The comfort of vehicle, handling and safety 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 being connected to the first row stomata on the sliding seat.To slide over not using the structure
Sliding is more smooth when being contacted with slideway end.
The utility model compared with prior art, has the advantages that：This kind of vehicle shock absorber when in use can
Rotating bar rotation is driven by the rotation of motor, is made by internal thread and externally threaded cooperation during rotating bar rotates
The position change on slide bar is slided over, since each second gear is different from the transmission ratio that the first gear engages, from
And upper end abuts against the end face of slideway during making some slide over vibration, some can be in cunning during sliding over vibration
It is free to slide in road, more also slide over vibration during lower face abut against slideway end face and some slide over and shake
Originally free to slide in dynamic process then to be abutted against with the end face of slideway, being changed by motor rotation can be free in slideway
The Oscillation Amplitude that the sliding sleeve quantity and sliding sleeve of sliding are abutted against with end face, to adjust the damping force of sliding bar, so that
Vehicle preferably adapts to different road surfaces, improves the comfort of vehicle, handling and safety.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model embodiment.
Fig. 2 is the partial enlarged view of Fig. 1.
Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 2,
Vehicle shock absorber, including fixed seat 1, sliding seat 2, working cylinder 3, slide bar 4 and spring 5 are provided in the fixed seat 1 several
Working cylinder 3, each inserted with slide bar 4 in the working cylinder 3,4 end set of slide bar in the working cylinder 3 has piston
