Abstract
The utility model belongs to an improved structure for bicycles. The utility model aims to design a mainspring aided bicycle. The utility model utilizes the pressure of the human body on the seat to give the existing bicycle with an auxiliary boosting force, and then the bicycle is rode in labor-saving. In order to achieve the goal, the lower end of the seat is provided with a seat spring to drive a drive rod, a transverse rod and a ratchet pawl drive a ratchet wheel to tighten a spring mainspring which is positioned in a ratchet wheel sleeve, the spring mainspring drives a rotor shaft to drive a chain wheel which is arranged on the rotor shaft, a chain drives a fly wheel, and then the riding auxiliary force boosting is completed. The labor saves 25%. The structure is simple, and the design is reasonable.
Description
The utility model relates to a kind of improvement structure to bicycle.
Traditional bicycle drives flywheel by sprocket wheel by chain and drives car body and advance, its power main source in the pedal of human body, can not utilize other position application force of human body.
Therefore, the purpose of this utility model is: design a kind of spring Bicycl with booster, utilize human body to give existing a kind of auxiliary reinforcing of bicycle to the pressure of stand so that ride and save labour.
The utility model is made up of vehicle frame and stand, the stand lower end is provided with the root spring, the stand lower end is connected with drive link, drive link drives cross bar, cross bar fuses with vehicle frame by the axle nail, the cross bar one end ratchet that is coupling, the body pawl drives ratchet, and ratchet is positioned on the ratchet sleeve, the ratchet sleeve middle-end is provided with rotor and rotor shaft is linked to be one, be provided with the spring of screw winding in the ratchet sleeve, an end of spring is positioned on the fastening nail of ratchet sleeve the inner, and the other end of spring is positioned on the epitrochanterian fastening nail, rotor shaft one end is established sprocket wheel, sprocket wheel is connected with flywheel by chain, and the car rear axle is provided with two flywheels, also is provided with a directed ratchet on the ratchet.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that: can utilize the pressure of body weight stand, especially car body jolts in getting on the bus or riding, the fluctuating of human body on stand, the pressure that stand is produced drives the ratchet rotating ratchet and tightens up spring and then drive the chain wheel drive flywheel to the bicycle reinforcing, when common this reinforcing can make cycling laborsaving about 25%.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Fig. 2 is the afterburning structural representation of the utility model sprocket wheel
Fig. 3 is the utility model ratchet sleeve and spring scheme drawing
The utility model is made up of vehicle frame 1 and stand 10, the stand lower end is provided with root marshall springs 11, the stand lower end is connected with drive link 15, drive link drives cross bar 7, cross bar fuses by axle nail 8 and vehicle frame, the cross bar one end ratchet 6 that is coupling, and ratchet drives ratchet 19, wheel is positioned on the ratchet sleeve 32, and ratchet sleeve 32 middle-ends are provided with rotor 29 and rotor shaft 20 fuses.Be provided with the spring 28 that screw thread curls up in the ratchet sleeve, one end of spring is positioned on the fastening nail 25 of ratchet sleeve the inner, the other end of spring is positioned on the epitrochanterian fastening nail 31, rotor shaft one end is established sprocket wheel 21, and sprocket wheel is connected with flywheel 17 by chain 18, and the car rear axle is provided with two flywheels, also be provided with a directed ratchet 23 on the ratchet, ratchet sleeve is coupling on fixed mount 22 by rotor shaft and bearing seat 26,30, is provided with spring 16 between cross bar and the ratchet.
During concrete the making, fixed mount is to be fixed on the vehicle frame by 3-4 fixation clamp 5 and screw 4 that is fixed as one with vehicle frame.Two ends, the center fixed bearing block 26,30 of fixed mount, the rotor shaft that is coupling in the bearing seat, fixed ratchet wheel cover and rotor on the rotor shaft, the ratchet sleeve periphery is provided with all ratchets 19.Rotor shaft one end is provided with sprocket wheel, be connected by one in the flywheel on two on chain and the car rear axle, the other end of rotor shaft can be provided with a brake disc 27, cooperate its outer end to be fixed on brake band on the car body, when stopping, check rotor shaft, for conventional confguration is identical with three-wheel vehicle rear wheel brake structure, so be not repeated.For ratchet one-way is rotated, with the fixing fixation clamp of car body on establish the pin 2 manual boosting-rod 3 that is coupling on it, manually the boosting-rod lower end directed ratchet 23 that is coupling is established spring 24 between the two and is resetted.Can play with hand reinforcing and orientation and block ratchet effect, manually the front end of boosting-rod is stuck on the edge of fixation clamp, can not move forward above the edge of fixation clamp.
The stand front end is provided with guide rod 9 makes the stand can not sway, the bottom of the fastening marshall springs of one end of screw rod 12, the expand tube 13 that the other end passes on the screw rod is connected the seat pipe that is arranged in the vehicle frame rear end jointly with the mother 14 of expanding, tighten screw rod, and female expand tube that enlarges that expands is fixed on screw rod on the vehicle frame.
During use, the conventional drive structure of bicycle is constant, when stand be subjected to human body gravity different press up and down the time, drive link moves down and drives ratchet by cross bar and lead ratchet and tighten up spring in it gradually, human body gravity jolts, and marshall springs 11 resets stand when alleviating, repeat to tighten up gradually spring, when spring is tightened to when being enough to tend to act flywheel, need not use the traditional sprocket wheel of pedal, the power of spring drives rotor shaft by rotor and then drives sprocket wheel and drives the flywheel car of tending to act by chain and advance, with laborsaving.
In a word, the utility model structure is comparatively simple, and the laborsaving convenience of riding is a kind of desirable spring Bicycl with booster.
