Abstract
The utility model discloses a single-handle double-brake mechanism for a bicycle, wherein a structure that a front brake and a rear brake are controlled simultaneously by a brake rod is adopted, when a rider presses a press brake rod with a single hand, the front brake and the rear brake of the bicycle brake a front wheel and a rear wheel respectively, and the rear brake brakes before the front brake; the brake lines of the front brake and the rear brake are integrally connected, and wrapped by a line divider shell, and then the front brake, the rear brake and the brake rod are connected; because the two brake lines are integrally combined, the two brake lines are dragged when the brake rod is pressed to drag the brake lines, and the line divider shell is used for providing a brake rubber for middle fixation as a substitute; the front brake line is finally connected with the front brake, the rear brake line is finally connected with the rear brake, and when the brake rod is pressed by adjusting the adjustment bolt, the rear brake brakes before the front brake; in this way, the burden of operating the two brake rods with both hands is reduced and the safety guarantee of the rider is increased, and the single-handle double-brake mechanism can be used as an independent fitting for a bicycle and assembled on a common bicycle. The single-handle double-brake mechanism has the advantages of being small in volume, simple in structure, and convenient to debug; and after two brakes are changed into one brake, the components of one brake can be saved.
Description
Affiliated technical field
The utility model relates to front brake and back brake and brake lever structural development and the mode that simplifies the operation on former bicycle.
Background technology
Bicycle can produce inertia when riding, and the faster inertia of riding speed is larger.When bicycle need to stop, need force wheel to stop operating by braking mechanism and realize.When using front wheel brake, between front brake and front wheel hub, by producing larger friction force, cause front-wheel to stop rolling, between front-wheel and ground, also produce larger friction force this moment, but under the effect of inertia, because bicycle and bicyclist's center of gravity is higher, rotation centered by front axle can occur, people from the company of causing is with the car danger of overturning forward, especially when descending is ridden fast, once use front wheel brake, tumble injury may occur at any time.There is above-mentioned accident when avoiding by bike, so must first brake with trailing wheel when riding fast.Particularly, when emergency situation occurs, by mechanical system, carry out voluntarily the trailing wheel of first stopping, then the front-wheel of stopping is very important.
On ordinary bicycle, have two brake handles, control respectively front brake and the back brake of bicycle, and two brake handles are also controlled respectively by two hands.If need brake when usually riding, both hands are controlled the brake handle trailing wheel front-wheel of stopping again of should first stopping and are had very large safety control.But in case of emergency, bicyclist is because for the moment flurried, there is no the trailing wheel of first stopping of the science front-wheel of stopping again while often pressing two brake handles, causes like this danger coefficient to raise, even cause this avoidable accident, and bicyclist often can not note these potential risks.And both hands are controlled two brake handles and are gone brake meeting very loaded down with trivial details.
Summary of the invention
Two hands coordination inconsiderate and trouble that two hands are controlled when overcoming bicycle brake.The utility model adopts a brake handle to control the structure of back brake and front brake simultaneously, when bicyclist's one hand is pressed a brake handle, bicycle back brake and front brake are checked respectively trailing wheel and front-wheel, and assurance back brake is stopped down prior to front brake, has greatly controlled and cut down the injury risk of motional inertia for people and Che.It is characterized in that: comprise the joint that is 1. connected into a brake cable by two brake cables, 2. frog metal case, 3. locating bush and 4. hollow adjustment bolt.Wherein, this frog metallic shell wall is provided with brake cable hole, and rear brake cable separates frog betal can from brake cable hole, connects back brake, and front brake cable is straight stretches out connection front brake from the hollow adjustment bolt in frog betal can bottom.That brake cable that two brake cables are linked to be stretches out from frog betal can top locating bush, connects single brake handle, and the adjustment bolt of this frog betal can bottom is directly connected to front brake bracket.The front brake connecting by brake cable and back brake are without changing.
the utility model solves the technical scheme that its technical matters adopts
The brake cable of front brake and back brake is connected into one by the mode of knitting or welding, with a metal sleeve, encase, be connected on the brake handle of handlebar.Because two brake cables have been connected into one, so can catch hold of two brake cables when pressing brake handle and pulling brake cable simultaneously.The effect of metal sleeve is that the antagonistic force producing when pressing brake handle is transmitted in the adjusting bolt of front and rear brake incessantly.Therefore connect and can not interspace between metal sleeve and the metal sheath of each brake cable, otherwise power cannot be applied on front brake and back brake by bicycle list handle double brake mechanism.The front brake cable passing through from bicycle list handle double brake mechanism will finally be connected with front brake, the rear brake cable passing through from bicycle list handle double brake mechanism will finally be connected with back brake, when adjusting bolt on front and rear brake and make to press brake handle by regulating respectively, while realizing brake, back brake is stopped down prior to front brake.
the beneficial effects of the utility model
The trailing wheel of first stopping carried out voluntarily by physical construction when this structure has not only ensured brake stop again before wheel mode, got rid of the risk that error in judgement artificial when emergency situation may cause, and alleviated the burden that both hands are controlled two brake lever.The most important thing is to increase bicyclist's safety control.
The use of bicycle list handle double brake mechanism will have two brake handles to be reduced to one on traditional bicycle, greatly saved the material for brake, reduced the cost of bicycle, once China is applied and will produce very considerable economic benefit as country's bicycle list handle double brake mechanism of bicycle use amount maximum.
Bicycle list handle double brake mechanism, by an individual components that is bicycle, has simple installation, feature easy to use, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
figure mono-
Bicycle list handle double brake mechanism is an individual components of bicycle.It is comprised of 4 parts:
1. the steel rope of one-to-two
2. frog shell
3. metal locating bush
4. hollow adjusting bolt
1. be that the brake cable of front brake and back brake is connected into steel cable by the mode of knitting or welding, and encase with a metal sleeve.
2. be metal sleeve, its effect is that the antagonistic force producing when pressing brake handle is transmitted in the adjusting bolt of front and rear brake incessantly.2. left end is connected with 3. inserting.Apart from 15 millimeters of places of right output port, have a circular hole as the use that derives rear brake cable, steel rope therefrom passes.
3. by guaranteeing that brake cable makes brake cable and metal sleeve keeping parallelism while entering 2., effectively avoid producing friction drag because scratching metal sleeve.3. left port is inserted directed for brake cable overcoat.
4. can be by the hollow bolt of steel wire penetrating centered by, having in the middle of bolt external diameter local is hexagon, for adjustment brake.
4. left end is connected with 2. inserting, and right-hand member is threaded into front brake of bicycle bracket.
This figure is the assembly drawing of bicycle list handle double brake mechanism.
