Abstract
The utility model relates to an auxiliary component for a bicycle, particularly an antivibrator with a flat steel spring and the antivibrator with a flat steel spring is used for reducing vibration generated in the running process of the bicycle. The utility model comprises an outer pipe, a spindle head and a damping spring sheathed on the spindle head. The utility model is characterized in that the damper spring is the flat steel spring which is wound to form a helical shape; outer screw threads are processed on the outer surface of the outer pipe which is sheathed with an adjusting ring and is connected with the fixed end of the damping spring. When used, the antivibrator with a flat steel spring of the utility model has the advantages of small spring permanent deformation, big stroke and further bicycle damping property improvement.
Description
Technical field:
The utility model relates to a kind of bicycle use accessory, is specifically related to a kind of damping device that is used for reducing the vibrations that produce in the bicycle running process.
Background technique:
Shock absorber is the part of bike suspension, and it is one of important driven unit of bicycle.Its main function is exactly to eliminate the vibrations that bicycle is produced when the conduct uneven road surface by damping spring, concussion when suppressing bounce-back after the damping spring shock-absorbing by vibration damper then and absorb the energy that passes the road shocks of coming by wheel, allow bicycle in brake or cross when curved simultaneously, situation that can run-off the straight.Shock absorber and bicycle usability are closely bound up, and what directly influence this performance is the performance of damping spring itself.All the time, the damping spring structure does not have any variation on the general shock absorber, and mainly focus on the hardness of damping spring, the research on the spring ratio, require simultaneously to have enough fatigue lives, its permanent deformation is little, promptly anti-relaxation property will be within the limits prescribed, otherwise vehicle body centre-of gravity shift will take place.And band steel generally all is to use as plane spring.
The model utility content:
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, provides that a kind of permanent deformation is little, stroke is big, can further improve the shock absorber of the band strip steel spring of bicycle damping performance.
The technological scheme that the utility model proposed comprises outer tube, main tapping and cover damping spring thereon, it is characterized in that described damping spring is around the strip steel spring of forming helical.
For regulating the pretightening force of damping spring, described outer tube outer surface is processed with outside thread, and regulating ring overlaps thereon, links to each other with the damping spring fixed end.
The utility model is by adopting by flat section steel bar around forming spiral helicine strip steel spring, compare with existing damping spring, its spring permanent distortion is little, stretching or compression stroke are big, can improve the hardness of spring itself and the tolerance of spring relatively, simultaneously, the pretightening force of set regulating ring adjustable springs on the outer tube, to regulate the elasticity of damping spring, prolonged the working life of spring, can obtain damping performance preferably by lower cost, meet the designs direction of present bicycle use damping spring.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1, the utility model comprises outer tube 2, main tapping 6 and damping spring 4, outer tube 2 and main tapping 6 are on same axis, its outer end is respectively equipped with the aluminium insert 1 that can link with other parts of bicycle, damping spring 4 is placed on outer tube 2 and the main tapping 6, the one end can be fixed on the outer tube 2, the other end with link to each other with main tapping 6 by spring seat 7, can under the drive of main tapping 6, stretch and compress; Between outer tube 2 and main tapping 6, be provided with impact bag 5, the concussion when may command damping spring 4 rebounds after car runs into the uneven road surface shock-absorbing, when avoiding curved simultaneously because damping spring about in the of 4 concussion and cause the forfeiture of tire earth-grasping force and tracking.The utility model is characterised in that described damping spring 4 is around the strip steel spring of forming helical, and its circle is apart from can be equidistant or unequal-interval.The spring that this spring pulls into respect to general round wire, its permanent deformation is little, the stroke that stretches or compress increases greatly, and weight reduces greatly, has tolerant preferably performance, simultaneously, its flat shape can make the spring external diameter become big, more meets long shock-absorbing stroke requirement, and the shock-absorbing performance of damping spring 4 is improved, the vibrations of bicycle have been alleviated, the working life of also having improved spring simultaneously.
As further improvement of the utility model, described outer tube 2 outer surfaces are processed with outside thread, regulating ring 3 covers thereon, its side end face and damping spring 4 fixed ends are fitted, by the position of turn regulating ring 3 on outer tube 2, the pretightening force of can regulate damping spring 4 and elastic force make it and outer tube 2 and main tapping 1 better matching, improve the usability of shock absorber.
The utility model not only can be used for the shock-absorbing of bicycle, equally also can be suitable for the equipment of small motor vehicle.
Claims (2)
1, a kind of shock absorber with strip steel spring comprises outer tube (2), main tapping (1) and cover damping spring (4) thereon, it is characterized in that described damping spring (4) is around the strip steel spring of forming helical.
2, the shock absorber of band strip steel spring according to claim 1 is characterized in that described outer tube (2) outer surface is processed with outside thread, and regulating ring (3) overlaps thereon, links to each other with damping spring (4) fixed end.
