Description

A kind of mountain region morpet

The utility model relates to a kind of bicycle, particularly a kind ofly is suitable for the morpet of riding in the mountain region.

China is known as bikedom, and the importance of bicycle in people's life, work has been well imagined.Though the quantity of China's bicycle is quite huge, thousand people one side, the existing bicycle that generally uses mostly is and prolongs the traditional design of having attacked decades, can not utilize bicycle running process medium power fully, to alleviate bicyclist's labour intensity.This respect shows that mainly people are when ride in the mountain region: when the bicycle descending, in order to control the speed of a motor vehicle of accelerating day by day, people often adopt the brake measure; When bicycle goes up a slope, keep certain speed in order to have kept car, people risk one's life to pedal again.

The purpose of this utility model provides and a kind ofly can make full use of the kinetic energy that descending produced in the bicycle running process, alleviates the novel mountain region morpet of bicyclist's exercise intensity.

The purpose of this utility model is achieved in that it comprises bicycle, is characterized in that: on the front axle of bicycle brake accumulator is installed, is fixed with power-transfer clutch on the front fork; Power-transfer clutch is made up of casing, expansion plate and driving gear set in it, casing is fixed on the front fork, be rotationally connected on the casing and have the pull bar of retracing spring, pull bar links to each other with expansion plate, slide on the expansion plate driving gear set is arranged, input gear in the driving gear set can be meshed with the wheel gear ring, transmits gear mesh on the hollow shaft of output gear and brake accumulator; Brake accumulator comprises the hollow shaft that is set on the axletree, hollow shaft is fixedly connected with the transmission gear near power-transfer clutch, the outside near this end is rotatably connected to the wheel gear ring by a thousand pieces of gold, the hollow shaft other end is provided with ratchet and matches with ratchet on the housing, housing and front fork are fixed, and the hollow shaft middle part is fixed with spiral type spring by baffle plate.

The utility model adopts by power-transfer clutch mutual action fixing on the brake accumulator of preceding axle mounting and the front fork, during the bicycle descending, car body glides under the effect of gravitional force, by the closed power-transfer clutch of pull bar, the input of the driving gear set in the power-transfer clutch at this moment, output gear transmits gear mesh with wheel gear ring and hollow shaft respectively, under its effect, hollow shaft produces rotate opposite with the wheel rotation direction, and then make on the hollow shaft by the fixing spiral type spring accumulation of energy of block, spiral type spring is realized self-locking by pawl-and-gearing in the process of accumulation of energy, thereby finish the accumulation of energy process, loosen the clutch; During cruising, power-transfer clutch is in the release position; When bicycle went up a slope or need power-assisted to ride, the rotation brake pull bar made ratchet separate with ratchet, so just rotated under the spiral type spring effect after the accumulation of energy, finally drove wheel by a thousand pieces of gold; The realization of whole operation realizes that by the brake accumulator and the power-transfer clutch that are installed on the car body whole apparatus structure is simple, and is easy for installation, can make full use of the kinetic energy that produces in the bicycle descent run process, practical, and repacking easily, is suitable for promoting.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model brake accumulator installation site figure.

Fig. 3 is the utility model power-transfer clutch installation site figure.

As shown in the figure, the utility model comprises bicycle 31, be fixed with power-transfer clutch 33 and brake accumulator 32 on it, outside the power-transfer clutch 33 is casing 1, pull bar 3 is rotationally connected on casing 1 sidewall, be fixed with retracing spring 4 between pull bar 3 and the casing 1, be used to realize resetting again after pull bar 3 actions, also be fixed with retracing spring 10 between expansion plate 7 and the casing 1, an end is fixed with slide block 5 in pull bar 3 casings 1, slide block 5 realizes that by the spinning in and out in expansion plate 7 sinks hole 8 the horizontal direction equipotential moves in casing 1, expansion plate 7 is fixed in horizontal motion on the slide shaft 6, slide shaft 6 is fixed on the casing 1 by screw 2 and nut 11, sliding on the expansion plate 7 has by input gear 13, the driving gear set that intermediate gear 12 and output gear 29 are formed, input gear 13 and intermediate gear 12 are fixed on the transmission shaft 19, output gear 29 is fixedly installed on the transmission shaft II30, driving gear set can wait displacement movement at next same work in the horizontal direction of effect of expansion plate 7, to realize the folding of power-transfer clutch 33, input gear 13 can mesh with wheel gear ring 25, output gear 29 can mesh with the transmission gear 27 on brake accumulator 32 hollow shafts 26, transmits horizontal throw and transmission shaft I between gear 27 and the wheel gear ring, the last input of II, horizontal throw is identical between the output gear; The core component of brake accumulator 32 is a hollow shaft 26 that is set on the axletree, hollow shaft 26 is provided with transmission gear 27 near an end of power-transfer clutch 33, the outside of this end is rotationally connected by a thousand pieces of gold 24 and wheel gear ring 25, the direction of a thousand pieces of gold 24 is consistent with the rotation direction of the working direction of wheel, the outside, middle part of hollow shaft 26 is fixed with spiral type spring 15 by block 23, the outside sealing cover of spiral type spring 15 has spring enclosing cover 14, spring enclosing cover 14 is fixed by back-up ring 17 and front fork, the other end of hollow shaft 26 is provided with ratchet 19, ratchet 19 is rotationally connected by bearing 18 and axletree, ratchet 19 be connected in the ratchet 20 that spring covers outward and match, realization is to the self-locking of the spiral type spring in the accumulation of energy process 15, ratchet 20 is fixed with retracing spring 22 with spring enclosing cover 14 places of being rotationally connected by nut 21, is beneficial to its normal playback.

Use the utility model, when the bicycle descending, car body glides under the effect of gravitional force, by pull bar 3 closed power-transfer clutchs 33, the input gear 13 of the driving gear set in the power-transfer clutch 33, output gear 29 transmit gears 27 engagements with wheel gear ring 25 and hollow shaft 26 respectively at this moment, under its effect, hollow shaft 26 produces rotate opposite with the wheel rotation direction, and then make on the hollow shaft 26 by fixing spiral type spring 15 accumulation of energys of block 23, spiral type spring 15 is realized self-locking by ratchet 20 and ratchet 19 in the process of accumulation of energy, thereby finish the accumulation of energy process, loosen the clutch 33; During cruising, power-transfer clutch 33 is in the release position; When bicycle goes up a slope or need power-assisted to ride, the pull bar that rotation is fixed on the nut 21 makes ratchet 20 separate with ratchet 19, so just, under 15 effects of the spiral type spring after the accumulation of energy, rotate, finally drive wheel, be released into kinetic energy by spiral type spring 15 savings by a thousand pieces of gold 24.
