Abstract
The utility model provides a rocker arm type vibration damper of a main supporting beam of a bicycle, which is mainly composed of a main (fixed) bicycle frame and a rocker arm type bicycle beam, wherein the main bicycle frame comprises a main steering pin sleeve, a seat cushion, a connecting valve, a regulating valve of the seat cushion, an inclined valve and a middle axle sleeve, and the rocker arm type bicycle beam comprises a rocker arm fulcrum, a supporting beam, a rear flat fork and a spring. The rear flat fork is connected with a supporting beam of a rocker arm as a whole, a rear wheel axle is taken as a starting point, a movable fulcrum connected via the rear flat fork and the front end of the supporting beam of a rocker arm is fixed to the back side of the main steering pin sleeve of the main bicycle frame or any position on the inclined valve between the main steering pin sleeve and the middle axle sleeve, and the supporting beam of a rocker arm is connected with the main bicycle frame by one to two springs. The structure extends a jumping radius and enhances the jumping freedom degree of the wheels. The utility model has the advantages of simple structure and convenient installation and maintenance without the need of special tools and professional maintainers, the rocker arm type vibration damper of a main supporting beam of a bicycle can be freely disassembled, assembled and maintained by people who slightly know mechanical common sense, and particularly damping effect is obvious; riders can feel comfortable.
Description
Technical field:
The utility model relates to a kind of shock absorbing apparatus of bicycle, the especially a kind of bearing beam of car owner voluntarily rocker-arm shock absorbing apparatus.
Background technology:
Being seen on the market at present frame shock absorbing apparatus, mostly be flat/tiltedly pitch the back vent rocker-arm shock absorbing apparatus of combination, the rocking arm fulcrum of this kind device is all before and after bottom bracket axle, (fulcrum and wheel base from) is nearer because the rocking arm radius, the spring length that adopts is short and hard, so this kind shock-absorbing sensory effect in practice process is not very desirable.
Summary of the invention:
In order further to improve the damping effect of frame, the utility model provides a kind of prolongation rocking arm fulcrum, strengthens the new structure of the radius of beating, and this structure can be brought into play the shock-absorbing effect to greatest extent and the vibrations that make the road surface reach vehicle body reduce to minimum.
The technical solution of the utility model is:
The utility model mainly is made up of master's (fixing) vehicle frame, rocker-arm car beam two parts.Main car frame partly comprises steering yoke bolt cover, seat cushion, logical, logical, oblique logical, the bottom bracket axle of seat cushion adjusting of connection; Rocker-arm car beam comprises rocking arm fulcrum, bearing beam, back chain stay and spring.Back chain stay and rocking arm bearing beam fuse, make starting point with hind axle, through after chain stay, rocking arm bearing beam front end bonded assembly moving fulcrum be fixed on any place on tiltedly logical between the steering yoke bolt cover back of main car frame or steering yoke bolt cover and the bottom bracket axle, be connected with 1～2 spring between rocking arm bearing beam and the main car frame.This structure to prolong the radius of beating, strengthened the degree of freedom of wheel bounce.
Rear wheel fork has been abandoned traditional flat/oblique fork in conjunction with coefficient structure, has only kept the reinforcement chain stay that fuses with the rocking arm beam.Embodied the terseness of body structure.
All adopt a public female intersection if any crossplot point between vehicle frame and the movable rocking arm.Moving fulcrum adopts bearing or axle sleeve structure.
The beneficial effects of the utility model are:
Simple in structure, installation and maintenance convenience need not special tool and specialized maintenance personnel, understand that slightly mechanical general knowledge is detachable and maintenance, and especially damping effect is obvious, makes the rider feel more comfortable.
Description of drawings:
Fig. 1 is conventional triangular frame and rocking arm beam partial structure scheme drawing;
Fig. 2 is single straight-through vehicle frame and rocking arm beam partial structure scheme drawing.
Fig. 3 is single curved be open to traffic frame and rocking arm beam partial structure scheme drawing.
Among the figure, steering yoke bolt cover 1, connect logical 2, tiltedly logical 3, bottom bracket axle 4, seat cushion are regulated logical 5, rocking arm bearing beam 6, moving fulcrum 7, back chain stay 8, spring 9.
The specific embodiment:
As figure; the moving fulcrum 7 of rocking arm bearing beam 6 front ends is connected in fixedly that the frame-steering stub overlaps in the pin sleeve of 1 back; the rear end connects back chain stay 8 and is installed on the hind axle; so just formed and can freely press close between master's (fix) vehicle frame and the rocking arm girder or the hinge type structure of diastole, between connection spring 9 just can support main car frame and absorb, weakens the vibrations that the road surface reaches main car frame to greatest extent.
Bottom bracket axle is fixed on tiltedly logical 3 lower ends of main car frame in the usual way, and as Fig. 1, the extending beam that also can directly be fixed on back chain stay 8 is certain point of rocking arm beam 6, as Fig. 2.
Shock-proof spring 9 comprises top spring or extension spring, optionally can be installed on any position between main car frame and the rocking arm beam.Both can see Fig. 2,3 with one or two top springs 9 connections; Also can connect, see Fig. 1 with extension spring 9.
When main car frame adopts conventional spider; rocking arm bearing beam 6 extends to the tiltedly any place on logical 3 between main car frame steering yoke bolt cover 1 and the bottom bracket axle 4; with moving fulcrum 7 with tiltedly lead to 3 or be close to steering yoke bolt and overlap 1 and be connected; form long rocker structure, be connected with 1～2 top spring or extension spring 9 between rocking arm beam 6 and the main car frame.
When main car frame adopted the single-pass vehicle frame, rocking arm bearing beam 6 extended to steering yoke bolt and overlaps 1 back, was close to steering yoke bolt cover 1 with moving fulcrum 7 again and connected, and bottom bracket axle 4 is fixed on the extending beam place of back chain stay 8 or is fixed on single curved logical lower end.
The utility model also is applicable to electric power mini-motorcycle, manual tricycle, motor-driven or electric wheel-chair vehicle, be a kind of purposes load-bearing widely, be used for the new structure of Light-duty Vehicle damping.
