Abstract
A converted flexible front folk liquid shake absorption of an auto-bike is provided and is composed of an upper outer canister (2), a front folk tube (8), an outer spring (4), a damper (5), a shake absorption oil, and a mixed air (7). The damper (5) is composed of a cushion spring (12), a piston valve system (6), and a bottom valve system (10). The front folk tube (8) is provided with an outer spring (4) in the end inserting to the upper outer canister (2); and the outer spring (4) is arranged outside a piston rod (3). One end of the piston rod (3) slides on a guide cover (14) with the other end is fixed with the piston valve system (6) through a guide seat (13). The front folk tube (8) is provided with the bottom valve system (10) on the other end. The shake absorption oil and the mixed air (7) is filled in the front folk tube (3) and the upper outer canister (2). A regulation hole (1) on the top of the upper outer canister (2) can regulate the oil pressure and the air pressure in the shake absorber. The shake absorber damper has the advantages of stable impact resistance performance, good shake absorption performance, long service life, and wide range of use.
Description
Technical field
The utility model relates to a kind of damping device, and especially a kind of motorcycle is inverted telescoping tube type front fork liquid gas vibration damper.
Background technique
In order to relax impact and the vibrations that are subjected to because of road is uneven in the process of moving with the decay motorcycle, guarantee the smoothness and the travelling comfort of driving, improve the working life of motorcycle and the stability of manipulation, be provided with dampening arrangement on the motorcycle.In the CN 2621963 Y patents of bulletin on June 30th, 2004, a kind of interior monotubular damper inversed front shock absorber is disclosed.This vibration damper adopts upside-down, and it is poor to solve existing front shock absorber usability, the problem that the friction in pairs resistance is big, but the damping force instability of this vibration damper, and impact resistance is poor, influences the ability and the travelling comfort of the different road conditions of adaptation of motorcycle.
The model utility content
The utility model has overcome the deficiencies in the prior art, provides a kind of damping force stable, and the motorcycle that impact resistance is good is inverted telescoping tube type front fork liquid gas vibration damper.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
This motorcycle is inverted telescoping tube type front fork liquid gas vibration damper and is made of last urceolus 2, front fork tube 8, outer spring 4, damper 5, damping oil and air mixture 7.Damper 5 by damping spring 12, piston valve be 6, bottom valve is 10, damping oil and AIR MIXTURES 7 constitute.Last urceolus 2 tops are provided with guide sleeve 14.Front fork tube 8 one ends are deeply gone up urceolus 2, can to-and-fro motion in last urceolus 2.The end that front fork tube 3 is deeply gone up urceolus 2 has outer spring 4, and outer spring 4 is enclosed within piston rod 3 outsides, the top that outer spring 4 one ends are deeply gone up in the urceolus part near front fork tube 8, an other end and guide holder 13 near.3 one in piston rod slides in guide holder 14, other one pass in the guide holder 13 with piston valve be 6 fixing.Outside guide holder 13 and piston valve are piston rod 3 between 6, also be with damping spring 12.Expose an end of urceolus 2 at front fork tube 8, being provided with bottom valve is 10.At the inner chamber 21 of front fork tube 8 and the inner chamber 23 of last urceolus 2, be full of damping oil and AIR MIXTURES 7.
Compared with prior art, the beneficial effects of the utility model are that damping force is stable, and impact resistance is good, can also conveniently adjust the oil pressure and the air pressure of front damper of motorcycle, and damping performance is good, and the life-span is long, and using scope is wide.
Description of drawings
Fig. 1 is the utility model structural drawing.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
This vibration damper is to adopt the upside-down mode, promptly goes up that urceolus 2 makes progress, front fork tube 8 is downward.When vibration damper is compressed, drive front fork tube 8 under external force and move upward, piston valve is 6 to move downward.Damping oil and AIR MIXTURES 7 are that damping hole in 10 flows to bottom valve chamber 20 from front fork tube 8 inner chambers 21 by bottom valve, produce compression damping power.The damping oil of front fork tube 8 inner chambers 21 and AIR MIXTURES 7 are that damping hole in 6 flows to piston valve pocket 22 by piston valve, produce compression damping power.When last urceolus 2 moved upward, damping oil and be damping hole in 10 flows to front fork tube 8 from bottom valve chamber 20 inner chamber 21 by bottom valve produced recovery damping force.Damping oil in the piston valve pocket 22 is that damping hole in 6 flows to front fork tube 8 inner chambers 21 by piston valve, produces recovery damping force.Damping spring 12 prevents that piston valve from being 6 with guide holder 13 direct collisions to take place.Be provided with adjustment hole 1 on last urceolus 2 tops,, can adjust the compression and the recovery damping force of vibration damper by the damping oil in the last urceolus 2 of adjustment hole 1 adjusting and the pressure of AIR MIXTURES 7.
For adapting to different demands, the recovery damping force of left and right sides vibration damper can be inequality.According to statistics to the motorcycle racing track, it all is to turn left that general motorcycle racing car travels, reseting performance during turning when having improved motorcycle racing, the reset speed of right vibration damper when effective attenuation is turned left, prevent the vehicle body over-tilting, adjust adjustment hole 1, make the recovery damping force of the right vibration damper of motor racing car bigger than left vibration damper.
