Abstract

The utility model relates to a bicycle with a vibration boosting device, and is composed of a shock absorber, a chain connected with an extension spring, a flywheel, etc. The shaking force produced by the bumpiness of a bicycle can be changed into the auxiliary driving force for driving the bicycle to travel forward. The universal components of a bicycle are used for the components of the boosting device of the utility model. The utility model has the advantages of simple structure, light structure, low cost, easy application and easy popularization.

Description

Bicycle with auxiliary vibration power device

The utility model is a kind of bicycle that can the shaking force when travelling changes propulsive effort into, particularly a kind of bicycle that shakes work-saving device that has.

Often because of Uneven road shakes, especially under the relatively poor situation of road conditions, evil is more encouraged in vibrations to bicycle, the people is not felt well, and influence road speed in advancing.Once the someone wanted to utilize bumper to add improvement to body construction eliminate the influence of shaking force to the cyclist as far as possible, but this to be a kind of way of passiveness.The innovation and creation of Chinese patent No. 89200875 " semiautomatic bicycles " by name, utilize arc-shaped rack, flywheel, bumper etc. to change the vehicle body shaking force that is taken place that advances into propulsive effort, though structure is also uncomplicated, but process special parts, easy not enough for producing new car and improving existing bicycle, and this structure seems heavy.

The purpose of this utility model is to provide a kind of and mainly utilizes existing bicycle universal component as the vibrations work-saving device, make and process the easier bicycle that shakes work-saving device that has, this bassinet structure is lighter, shaking force can be changed into the auxiliary driving force in advancing.

The utility model is achieved in that by constituting the vibrations work-saving device with extension spring bonded assembly chain, flywheel, bumper.Spring terminal and chain end in this device respectively with vehicle body or vehicle body extension on 2 be connected, one of them point of connection should be located on the position that as far as possible is higher than this flywheel.For the work of the original driving wheel disc of not overslaugh, flywheel, the flywheel of work-saving device can be loaded on the wheel left side.Chain is connected on the flywheel.For loss of weight and cost-cutting, available cable wire replaces not having with flywheel in the chain part of meshing relation.At the front-wheel or the trailing wheel mounting shock absorber of needs installation servo-unit, this bumper can be installed between front axle and handlebar; Or be installed between rear axle and the vehicle seat.

The bicycle of vibrations work-saving device is installed, and distance can change between the bumper upper and lower side when the vehicle body vertical tremor.When this distance shortened, extension spring shrank, and affected chain movement and drove flywheel idle running, when bumper resets, forced extension spring to stretch, and affected gear to travel forward, and for the bicycle in travelling increases propulsive effort, made the cyclist feel laborsaving.Influence the speed of a motor vehicle when particularly road conditions are bad, have the bicycle that shakes work-saving device and be subjected to jolting big more, the auxiliary driving force of generation is big more, can alleviate the driving difficulty of road conditions when bad.This work-saving device used unit is the common commodity of bicycle universal component or market, and weight and volume is all little, is favourable to transforming existing bicycle or producing new car, implements easily.

Be described in further detail below in conjunction with accompanying drawing.

Fig. 1 has the bicycle structure scheme drawing that shakes work-saving device.

Fig. 2 is used to install three orifice plates of front-wheel bumper.

In accompanying drawing 1, three orifice plates (5) are for connecting the connecting device of the bumper (1) about stem (being vertical tube of front fork originally) and front-wheel.Flywheel (2) is installed on the front wheel spindle skin, extension spring (4) one ends link to each other with three orifice plate fronts, the other end links to each other with chain (3), the chain other end links to each other with three orifice plate rear portions, chain middle part and flywheel (2) engagement, when vehicle body vibrations handlebar presses down, bumper (1) shortens, spring (4) contraction affects chain and makes the flywheel reversing, but it is inoperative to front-wheel, after bumper resets, spring (4) reset and affect chain (3) make flywheel forward rotary flywheel promptly drive front-wheel and rotate forward.When trailing wheel is installed this work-saving device, can be at Li Liang (6) top installation shaft bolster (11), and be connected lever (7) with axle by bearing.Lever (7) rear end connects vehicle seat support (8), vehicle seat support (8) is gone up vehicle seat (10) is installed, near the vehicle body of the front portion of lever (7) extension spring bumper (9) the connection axis; Perhaps connect vehicle seat support (8) and rear wheel fork with bumper (1 '), also can adopt simultaneously by two kinds of bumpers in the trailing wheel left and right sides.Flywheel (2 ') is installed on the backshaft skin of the left side of rear wheel, and chain (3 ') end is loaded on the front end of lever (7), and an end is connected with extension spring, and the other end of spring is loaded on the upright beam (6).When vibrations pressed down vehicle seat, the lever front end affected chain forward, and the chain driven gear rotates forward, for trailing wheel increases propulsive effort.Can also be the other installation side by side of flywheel (2 ') flywheel (2 "); extension spring is loaded on the vertical shaft (6); (2 ") bonded assembly chain, one end is loaded on the vehicle seat support (8), and like this, (power when 2 ") can be risen vehicle seat support (8) changes the power that trailing wheel advances that drives into to flywheel with flywheel.In order to increase the rider traveling comfort backrest (11) can be installed behind vehicle seat, backrest (11) can with a rod hinge connection, connecting rod and vehicle seat support are hinged, and be provided with a support hook is installed, so that backrest can be upright, can make backrest when this backrest is upright, overturning can play the effect of covering vehicle seat forward, prevents to expose to the sun and rain; Turn over backward and can sit the people and increase carrying capacity.Fig. 2 is three orifice plates that are used to install the front-wheel bumper.(12) be the bumper connecting bore, (13) are the stem connecting bore, can establish two apertures that connect extension spring and chain (or cable wire) on three orifice plates.
