Abstract
Provided is a bicycle with a faster self-propelled device. The bicycle comprises a front wheel, a rear wheel and a bicycle frame used for supporting and fixing the front wheel and the rear wheel. Pedals are arranged on the lower portion of the bicycle frame and fixed on a drive shaft which is driven to the rear wheel through a first chain. The bicycle is characterized in that an elastic middle shaft for bearing gravity of a bicycle seat is arranged in a sleeve cylinder disposed under the bicycle seat in sleeved mode. Straight teeth are arranged under the middle shaft and drive a second chain through driving of a gear series. The second chain is meshed with a one-way wheel which drives the rear wheel and rotates in a single direction. Through the action of gravity, the middle shaft drives the straight teeth to drive the one-way wheel so as to drive the bicycle to move forwards. The bicycle can be speeded with a little strength, and effort of people to step on the pedals to move the bicycle is eliminated. The gravity of the people can be effectively converted into driving power of the bicycle to move forwards, and the bicycle brings convenience to the life of the people. The effort for riding the bicycle is saved.
Description
[technical field]

[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
A kind of bicycle with acceleration motorized cart, comprise front-wheel, trailing wheel and support be the vehicle frame of front-wheel trailing wheel fixedly, has pedal at bottom of frame, pedal is fixed on the axle drive shaft, axle drive shaft drives to trailing wheel by the first chain 16, it is characterized in that, having one in the below-seat sleeve bears vehicle seat 1 gravity and flexibly is sleeved on axis 2 in the sleeve, described axis below has straight-tooth 8, and described straight-tooth 8 with by train of gears transmission and the second chain gear, and described the second chain and one-way wheel 13 engagements of can only single direction rotating that drive trailing wheel, from constructional drawing 1, can find out that described bicycle has two cover power systems simultaneously, trailing wheel can be stepped on the first chain that brings by pedal simultaneously as driving wheel and rotate and drive, and also can be driven by the rotation of the second chain 12 of straight-tooth transmission.
Described flexibly suit refers to that axis 2 is enclosed within the sleeve 6, and at axis 2 sheathed springs 4, spring 4 one ends are stuck on the middle joint 5 on the axis, and an end is stuck on the ring-shaped baffle 7 in the sleeve.Spring 4 makes axis 2 up and down springing in sleeve 6 under gravity and the continuous exchange interaction of elastic force.
Axis is provided with linear bearing 3 in two ends about in the of 2 in sleeve, and described spring is the bumper and absorbing shock spring.
Described train of gears comprises that one is realized being in transmission connection with gear 9 coaxial rotation/disengaging the sprocket wheel 11 of two states switching with straight-tooth 8 gears in meshs 9 with by power-transfer clutch 10.
Described gear 9 is installed on the same turning cylinder with sprocket wheel 11, on both relative end faces, has the corresponding wedging position that can mesh, has the external tooth 14 of protrusion at gear, and at sprocket wheel the internal tooth 15 that caves in is arranged.
Described power-transfer clutch 10 parts are pressed on sprocket wheel 11 lateral surfaces, and another part loosens ground mode driven gear axial direction by Compress Spring compression and moves, and switch to break away from sprocket wheel internal tooth engagement/with the sprocket wheel internal tooth to mesh two states.At power-transfer clutch a Compress Spring 17 is arranged, internal tooth 15 at the effect lower sprocket 11 of Compress Spring 17 is meshing with the external tooth 14 of gear 9, to be passed by the power steering that straight-tooth 8 transmits with sprocket wheel promotion wheel and march forward, steel wire in power-transfer clutch is to cooperate with spring to mesh and the power position of separating with two parts of dynamic clutch, the first steel wire 18 is connected to right brake working with brake one, when drag, also simultaneously disengaging of clutch has been opened and guaranteed emergency, the second steel wire 19 is connected to the separation handwheel 20 on the handlebar left side, separation handwheel 20 tensions the second steel wire 19 of going around when the walking go-cart separates power-transfer clutch so that go-cart, unclamp in the time of by bike and separate handwheel by the power-transfer clutch return, internal tooth and external tooth mesh and people's the gravity that moves downward can be changed into the power that promotes wheel fully.
Described sprocket wheel 11 and the second chain 12 keep engagement constantly, and the Bidirectional Conduction motion.
In this utility model, the resistance of bicycle is mainly from cyclist's oneself body weight, when people's gravity pressure is on seat board, because Action of Gravity Field, with past the pressing down of axis that is enclosed within the sleeve, at this moment, the straight-tooth of axis below is snapped to gear, the driven gear circular-rotation, by the external tooth engagement of gear and the internal tooth of sprocket wheel, the gear that is in engagement must drive the rotation of sprocket wheel 11, and sprocket wheel 11 transmissions are to chain 12, and the rotating torque on the chain 12 has finally driven the one-way wheel 13 on the bicycle rear.
Figure cathetus bearing 3 is parts of guaranteeing that axis 2 and straight-tooth 8 move up and down all the time, keeps the closely meshing of straight-tooth 8 and gear 9, and reduces the friction of axis 2 and straight-tooth 8 up-and-down movements, increases motion frequency, improves power; Its effect of manying that the external diameter of middle joint 5 is larger than the internal diameter of spring 4 is that the power that spring 4 makes progress resilience is passed to vehicle seat 1 to realize crank motion; Plate washer 7 blocks and is unlikely to glide increase resilience dynamics when spring 4 presses down; Sleeve 6 is the original gusseted pipes of bicycle, and above accessory is installed in pipe, and realization is simplified, simplification, lighting.
