Abstract
The utility model relates to a starting and accelerating booster for a bicycle and a tricycle, and the utility model is composed of a flywheel, pinch wheels, a spiral spring, and a box body. The flywheel is fixedly connected at a large end of a main shaft sleeve, and the spiral spring is fixedly connected at a small end of the main shaft sleeve through a connection sleeve; the main shaft sleeve is sheathed on a main shaft supporting on the box body, and the box body is arranged on a bicycle frame of a connection back wheel at the right side of the bicycle; the bicycle chain is embedded with the flywheel and is guided by the pinch wheels at both sides. When the chain of the bicylce is rotated backwardly, the flywheel is transmitted by the chain, and the spiral spring is fastened to store energy; when the bicycle is started or accelerated, the spiral spring releases the energy, the elastic force of the spiral spring and the pedal force of a rider are combined, and the ride of the bicycle is easy. The utility model has the advantages of convenient installation, easy and labour saving ride, favorable for the traffic safety, etc.
Description
The utility model relates to bicycle, refers in particular to a kind of for starting and accelerating booster that bicycle, three-wheel vehicle use.
China has the maximum country of rickshaw in the world, comprising: bicycle, derailleur, large and small three-wheel vehicle etc.; Car is many, the people is many, crowded traffic, so the traffic jam of being brought, and traffic accident constantly occurs, with regard to the unpowered vehicle accident, except that other reason, starting or quickening of unpowered vehicle all needs than the effort of normally riding, this fact, perhaps be to cause that the bicyclist should quicken, this is ridden soon and powerless, this is slow, this stops and be reluctant to stop, and embraces idea of leaving things to chance, the basic reason that causes the accident, and be the arch-criminal that ought to do not scolded.Particularly variable speed bicycle is when selecting for use fast gear or three-wheel vehicle load-carrying to ride, all the more so, frequent the brake reduction of speed or the parking that are forced to because who is unwilling, produce thus some by force, rob and go, turn suddenly, bore suddenly, this evitable accident takes place, and go slowly or with stopping in helpless following, during with the cycling that starts, more be difficult to walk.
The purpose of this utility model, exactly in order to overcome above-mentioned deficiency, the servo-unit that provides a kind of bicycle, three-wheel vehicle to start and quicken, make the anti-resistive enhancing of car, make the performance of car more perfect, make car start or when any scanning frequency, all can be at any time, give one a leg up everywhere, make the bicyclist feel the brisk effect of riding that the sort of former incompetence reaches of maybe can experiencing freely.
The purpose of this utility model is achieved in that a kind of bicycle, three-wheel vehicle start and accelerating booster, are made up of flywheel, pinch roller, volute spiral spring, casing etc.
A. bicycle freewheel is fixedly mounted on the big end external diameter of main brass of ladder shaft part, and described main brass is loaded on the main shaft with normal-running fit, and described main shaft supporting is in the axis hole of casing;
B. volute spiral spring, its the inner is fixed in adapter sleeve, this adapter sleeve is fixed on the small end external diameter of main brass, locating piece is equipped with in the outer end of described volute spiral spring, this locating piece is corresponding with the protruding pin position in the protruding pin frame that is contained on the casing circumferential outer edge face, is subjected to the spacing of this protruding pin, and there is the oblique angle described locating piece end, the orientation of this volute spiral spring is: when the bicycle jack, volute spiral spring screws;
C. in the appropriate location of the casing of described flywheel both sides, respectively there is one to be contained in pinch roller on the wheel pressing shaft with normal-running fit, this wheel pressing shaft is contained in the axis hole of casing, and described pinch roller edge has and the corresponding to teeth of flywheel, and its teeth centre plane and flywheel teeth centre plane coincide.
In preferred embodiment, protruding pin in the described protruding pin frame that is loaded on the casing circumferential outer edge face is cylindrical, there is radially outstanding locating convex block its appropriate location, middle part, described protruding pin frame is divided into three ply board, flaggy lower plywood has circular hole corresponding with the protruding pin diameter on it, the circular hole of its intermediate plate has vertical fluting to pass through to allow protruding pin and radial location projection thereof, the spacing of the spacing of described top plate and intermediate plate and intermediate plate and lower plywood can allow that the locating convex block of protruding pin rotates, when the radial projection of protruding pin is between intermediate plate and lower plywood, the locating piece that the casing inner peripheral surface suitably highly blocks the volute spiral spring top is stretched in the lower end of described protruding pin, when volute spiral spring together rotates with the main brass that flywheel is housed, this locating piece limitation of movement system and volute spiral spring is screwed, when the radial projection of protruding pin is between intermediate plate and top plate, the lower end of described protruding pin is concordant with the casing inner peripheral surface, make the motion of volute spiral spring top locating piece unrestricted, and make volute spiral spring ineffective.
Described casing is circular, is cooperated with seam by the two halves of middle branch to form, and flywheel and pinch roller are installed in its outer side box body, and volute spiral spring is installed in side box body in it, along four jiaos in casing parting face the lug of adorning bolt is arranged, and bolt up becomes demountable connection.
The top of the outer side box body of described dress flywheel is connected with screw rod, this screw rod and centering block are to be threaded, described centering block is articulated in the middle part of link span with lateral pin, there is clip at the two ends of described link span, this clip is connected in the vehicle frame of bicycle, but become demolition to be connected so that screw is fastening with vehicle frame, casing has been possessed have with because of reach about the blockchain that speed change produced angle correcting with closing property.
In another embodiment, the described bicycle freewheel structure that is loaded on main brass is substituted by following structure; Be shaped on unidirectional ratchet on the big end external diameter of step-like main brass, ratchet is housed in the Case of fly-wheel, between inboard slideway of Case of fly-wheel and left and right shelves lid ball is housed, the big end diameter of axle of left and right shelves lid with the stepped appearance main brass is fixed together with screw.
The utility model has following positive beneficial effect:
1. this servo-unit internal cause has volute spiral spring to participate in drive mechanism, has had that storage, exoergic and institute's storage power thereof convert elastic force to and with the large and small function of swinging to release of power.Because of elastic force has widely with closing property, so no matter with any chain drum storage power of reversing at a slow speed, it all can just change chain drum power mutually and unification with any fast speed, so the same usefulness of two power is this kind phase and not only reinforcing, the also characteristic of Jia Suing.This is that other (energy is changed mutually) change-speed box (reinforcing must reduction of speed) is beyond one's reach effect.
2. simple installation, the custom that serviceability is fit to ride is dynamic, and power is fast, power-assisted is timely, power-assisted is large and small arbitrarily, whenever back-pedal all can, like this when riding, before waiting to open, start, quicken, hinder by force, hinder in advance, stopping in advance, had the power that own this incompetence reaches very easily, fallen obviously, just same usefulness, maximum power-assisted can surpass cyclist former accessible a times.
3. move axially the protruding pin that is installed in the protruding pin frame, can servo-unit be worked or inoperative, for choosing at random when riding.
4. have self-safety guard-safeguard: when volute spiral spring exceeds predeterminedly when screwing scope, the locations of wind spring upper end can automatic slippage, avoids spring to twist off.
