Abstract
The utility model relates to a device of gravity drive for bicycle, belonging to the improvement of the existing bicycle drive systems. The technical characteristic of the utility model is that a power lever which can move up and down is connected under a vehicle seat, and the power lever drives the power to a big chain wheel by an umbrella-shaped spur gear, and umbrella-shaped pinion, two star wheel chain wheels and chains connected with the star wheel chain wheels on the end of the fulcrum to match with the original drive system to drive the bicycle forward solely or unitedly. The utility model uses weight of the human body to drive the bicycle forward to ease people's physical output and make the cycling lowering.
Description
The utility model relates to a kind of bicycle Gravity transmission equipment, belongs to the improvement of bicycle transmission system.
Existing bicycle, its type of drive has foot pedal type, shaking, and they realize bicycle forward, all will consume cyclist's muscle power.
The purpose of this utility model is: providing a kind of serves as the transmission device that drives power with human body self gravity, cooperates existing transmission mechanism of bicycle, thereby makes the people laborsaving by bike.
The technical solution of the utility model is: a kind of bicycle Gravity transmission equipment, comprise vehicle seat, transmission device on vehicle frame and the vehicle frame, it is characterized in that: on vehicle frame, be fixed with two groups of bearings, they are supporting gear wheel shaft and sprocket shaft respectively, wherein be connected with the umbellate form spur gear on the gear wheel shaft, gravity lever and pull back spring, be fixed on the sprocket shaft with umbellate form spur gear ingear miniature gears, have two identical their interior covers of ratchet sprocket wheel of structure to be separately fixed on the sprocket shaft and axis on, with two in cover ingear two overcoats link together by the chain of a closure, ratchet sprocket wheel overcoat on the axis is captiveed joint by adapter sleeve with the hinge wheel of bicycle, and vehicle seat is fixed on the end of power lever.
The bicycle other parts that match with the utility model Gravity transmission equipment all are prior arts.It is convenient for Gravity transmission equipment is installed, this programme design-calculated chassis frame part is generouser, the umbellate form spur gear is coaxial the connection with the gravity lever on the vehicle frame, two ratchet sprocket wheels that structure is identical, the one-way only operation that is meshing with each other of their inside and outside cover, two teeth that put outward cooperate with the chain of a closure, and two ratchet sprocket wheels are linked together.Pull back spring one end that is wrapped on the gear wheel shaft is fixed on the gear wheel shaft, and the other end is fixed on the vehicle frame, and it can promote gear wheel shaft and rotate return, when power lever is not done work, and self-return, the arc length of umbellate form spur gear is the length of the upper and lower motion of power lever.People's seat is on vehicle seat the time, the gravity of human body moves downward the power lever on the vehicle seat, the power lever other end is that fulcrum moves downward with the gear-bearing, coaxial umbellate form spur gear rotates identical angle thereupon, rotate with umbellate form spur gear pinion in mesh, driving overcoat with cover in the coaxial ratchet sprocket wheel of miniature gears rotates simultaneously, chain gear by cooperating again with overcoat, ratchet sprocket wheel overcoat on the axis is rotated simultaneously, because this overcoat and interior cover individual event work, this overcoat and coupling sleeve and hinge wheel are fixedly connected, and institute drives the driving system work in the prior art so that hinge wheel rotates.When human body gravity leaves vehicle seat and is placed on the pedal, spring promotes the gear wheel shaft return, make coaxial umbellate form spur gear, power lever return, turn round simultaneously with umbellate form spur gear ingear miniature gears and with the interior cover of the coaxial ratchet sprocket wheel of miniature gears, because interior cover and overcoat are ratchet one-way work, so overcoat does not rotate with interior cover during return, vehicle seat is with entering the work of gravity transmission next time after the lever return.When with the pedal car, axis and the interior cover rotation of fixing with axis, with cover ingear overcoat in this, coupling sleeve and the hinge wheel fixing with overcoat rotate, hinge wheel rotates by original transmission system drives rear wheel, two kinds of propulsive efforts can work independently respectively, also can work simultaneously, when working simultaneously, the interior cover of ratchet sprocket wheel and overcoat are rotated by the effect of two kinds of power respectively in the same way, when inside and outside cover meshes rotational synchronization, drive hinge wheel jointly and rotate, when asynchronous, slide between the interior overcoat.
Because seat relies on the upper and lower activity of gravity of human body self on the vehicle seat of bicycle, bicycle is advanced, it drives bicycle jointly in conjunction with existing type of drive with pedal and advances, can realize labour-saving purpose by bike, in addition, because power lever compares the lever of connection pedal to four times of the youthful and the elderlys, they all are by the hinge wheel chain power to be passed on the rear wheel, so the working power lever has strengthened the moment of power, make driving laborsaving.
Fig. 1 is the structural representation of the utility model bicycle Gravity transmission equipment.
Fig. 2 is that the B of the utility model Fig. 1 is to view.
An accompanying drawings embodiment of the present utility model.
Vehicle seat among the figure (17) is installed in an end of power lever (9), power lever (9) is that the pipe grafting of two rank forms, its length is adjustable, the other end of power lever (9) is fixed on the gear wheel shaft (2), two bearings (23) (24) of support teeth wheel shaft (2) are fixed on the vehicle frame (8), bearing (23) (24) is the fulcrum of power lever (9), also be connected with umbellate form spur gear (3) and pull back spring (5) on the gear wheel shaft (2), the bearing (22) (25) that is fixed on the vehicle frame (8) is supporting sprocket shaft (26), miniature gears (7) is arranged on the sprocket shaft (26), miniature gears (7) and umbellate form spur gear (3) engagement, sprocket shaft (26) is affixed with the interior cover of ratchet sprocket wheel (4), the one-way only operation that is meshed with the overcoat of (4) of the interior cover of ratchet sprocket wheel (4), on the axis (11) of bicycle, be connected with the interior cover of ratchet sprocket wheel (14), (14) interior cover is meshed with the overcoat of (14), one-way only operation, the overcoat of the overcoat of (4) and (14) is linked together by the chain (6) of a closure.Rotate synchronously, the overcoat of (14) and hinge wheel (10) are fixed together by adapter sleeve (15).(1) is handlebar in this accompanying drawing, and (12) are the pedal thighs, and (13) are pedals, and (16) are change-speed boxs, and (18) are shelf, and (19) are tower speed change ratchets, and (20) are trailing wheels, and (21) are front-wheels.These all are prior arts.
