Abstract
An auxiliary device for the treading power transmission shaft of a bicycle comprises a vehicle frame, two pedals, two cranks, a flywheel shaft, a sprocket wheel, a chain and a trailing axle member. When a user treads the bicycle, the power is transmitted to a trailing axle through the cranks, the flywheel shaft, the sprocket wheel and the chain, drives a rear wheel and moves the bicycle forward. The left and right sides of the vehicle frame are each provided with a leg pedal, and the leg pedals are arranged under the thighs of a rider in such a manner that one is situated above the other. Each leg pedal is connected with a first rotating shaft through a leg pedal connecting rod, and one end of the first rotating shaft is connected with a second rotating shaft on the vehicle frame through a pole. Bevel gears at the upper and lower ends of a transmission shaft in the vehicle frame are respectively engaged with gears of the second rotating shaft and the flywheel shaft. The length of the leg pedal connecting rod is adjustable, and the length of the pole is adjustable. Speed of the bicycle and the endurance of a rider are improved. The auxiliary device is laborsaving.
Description
Technical field
The leg that the utility model relates to a kind of bicycle steps the power transmission shafr auxiliary device, relates in particular to
The left and right leg pedal of new clothes on a kind of bicycle is transmitted in stretcher with shank power by second rotating shaft and transmission shaft and produces power, drives the efficient and the endurance of bicycle with increase.
Background technology
General bicycle more has the function of motion concurrently except for the instrument of riding instead of walk, therefore receives popular liking deeply; And bicycle is to utilize foot-operated forcing on the pedal; Drive wheel with chain, become to making bicycle to advance, this kind is prone to cause that rider's lap and Calf muscle crowd's is tired out for the mode of power; Not only can influence rider's endurance ability, more can influence rider's speed.
Because the thigh muscle group is one of the strongest muscle of human body, and be the basis of whole body strength, when trampling bicycle and make potential energy and change, if can suitably stress on back crowd's leg flesh, can alleviate the load of anterior muscle of thigh flesh and muscles of leg; If use leg muscle, just can increase strength and efficient that potential energy changes, and then increase speed and the endurance that drives as kinetic energy.
The utility model content
The utility model technical problem underlying to be solved is, overcomes the above-mentioned defective that prior art exists, and provides a kind of leg of bicycle to step the power transmission shafr auxiliary device, and its increase drives the speed and the endurance of bicycle, reaches the labour-saving effect.
The utility model solves the technical scheme that its technical matters adopted:
A kind of leg of bicycle steps the power transmission shafr auxiliary device; Comprise vehicle frame, two stretchers, two cranks, flywheel shaft, sprocket wheel, chain and hind axle member; Wherein step on bicycle via crank, flywheel shaft, sprocket wheel and chain with manpower; Be passed on the hind axle, drive trailing wheel bicycle is advanced; It is characterized in that: the vehicle frame left and right side is respectively established a leg pedal; This leg pedal is arranged on the bottom of rider's thigh with mode one on the other; Each leg pedal is to be connected with first rotating shaft with the leg pedal rod; First rotating shaft, one end utilizes pole to be connected with second rotating shaft on the vehicle frame, the crowngear of vehicle frame in-to-in transmission shaft upper and lower end respectively with the gear mesh of second rotating shaft and flywheel shaft.
The leg of aforesaid bicycle steps the power transmission shafr auxiliary device, and wherein the length of leg pedal rod is adjustable structure.
The leg of aforesaid bicycle steps the power transmission shafr auxiliary device, and wherein the length of pole is adjustable structure.
The leg of the utility model bicycle steps the power transmission shafr auxiliary device, mainly is left and right each leg pedal of one of new clothes on general bicycle, and this leg pedal is to utilize second rotating shaft and transmission shaft etc. to link structure; Mode one on the other is arranged on rider's thigh downside; The upper-lower interactive motion drives rotating shaft in the time of down and transmission shaft rotates, and wheel disc like flying dallies in the time of up; The kinetic energy that produces with thigh strength is passed on the stretcher of general bicycle; Relend and be passed to hind axle by crank, flywheel shaft, sprocket wheel and chain and produce kinetic energy, drive the speed and the endurance of bicycle, increase the efficient that drives and also reach the labour-saving effect with increase.
