Abstract
The utility model discloses an effort-saving bicycle which is an improvement based on the existing bicycle. The utility model of effort-saving bicycle arranges a lever beam on the bicycle frame; the lever beam is divided into two which are connected with each other by hinging holes; the front end is a fixed body welded on the front fork tube; the back end is a lever body; the support arm of the lever is welded under the pin axel hole of a flashboard; the back end of the flashboard is welded with the lever body; the other end of the lever support arm is arranged on the top board; the up end of the top board is welded on the fixed body of the lever beam and the lower end is welded on the front beam of the bicycle; the back end of the lever beam is welded with a fixed upright tube of the fixed frame; and the lower end of the upright tube is separated from the back beam. The frame upright tube of the utility model of bicycle is separated from the frame, thus when the body of a rider is on the bicycle frame, the gravity changes the force transmission direction through the bicycle seat, lever support point, support arms, and the top board to make the gravity directly act on the front frame and give the bicycle a forward force to achieve the effort-saving effect and set a absorber below the lever beam. The utility model of bicycle has the advantages of effort-saving, good shake absorption effect, and strong comfort feeling.
Description
Technical field
The utility model relates to a kind of technical field of bicycle.
Background technology
China is bicycle big country, and bicycle is in the history of the existing last 100 years of China, and near perfect degree, the bicycle of various models and style is complete technically for bicycle.People are doing further improvement to bicycle aspect laborsaving and the damping in recent years, all because of structure is complicated, original bicycle is changed greatly, and implemented.
The utility model content
The purpose of this utility model is to provide a kind of labour-saving bicycle simple in structure, and this car acts on auxiliary power in advancing with cyclist's self gravitation, thereby makes bicycle labor saving.
The utility model is a kind of improvement to existing bicycle, the utility model labour-saving bicycle comprises handlebar, vehicle frame, vehicle seat, front-wheel, trailing wheel and transmission device, the lever beam is set on the vehicle frame, the lever beam is that two bodies connect by hinge hole, front end is that fixed body is welded on the vertical tube of front fork, the rear end is a lever body, the lever support arm is welded on below the plate body pin shaft hole, plate body rear end and lever body welding, the lever support arm other end is arranged on the top board, the top board upper end is welded on the lever beam fixed body, and the lower end is welded on the front beam of frame; Lever beam rear end and the fixedly fixed riser welding of vehicle seat, the lower end of standpipe and the vehicle frame back rest disconnect.
Below the lever beam buffer beam is set, two ends are separately fixed between the front and rear beam of vehicle frame, and the centre is provided with damping spring.
The utility model labour-saving bicycle, vehicle seat standpipe and vehicle frame disconnect, when cyclist's health is sitting on the bike saddle, his gravity changes the power transmission direction by bike saddle, balance pivot, support arm, top board, makes gravity directly act on front frame, gives power forward of bicycle, this power one is the foot-operated power that alleviates the cyclist, the 2nd, the buffering bicycle front fork reaches the labour-saving purpose to ground-surface application force, makes the people in flat road surface down-hill sensation be arranged by bike the time.Simultaneously can below the lever beam, buffer beam be set, improve cyclist's comfort.
