Abstract

Both hands move bicycle booster is one kind and installs in the mechanical device of bicycle handlebar with the front truck fork. Use both arms to push down the handle in turn and as the power input, through the gear drive who forms by semi - circular gear, change -speed gearing, carrier gear, bevel gear group etc. Amplify power and export in the bicycle front axle, assist to ride, and do not influence the former driving system normal use of bicycle. The device can improve riding speed, reduces the climbing degree of difficulty, alleviates the low limbs fatigue that the long distance was ridden and is brought, through the alternative action that pushes down the handle of two arms in order to lighten the discomfort of riding passerby's upper limbs and riding and being brought because of the long distance.

Detailed description of the invention

This Accelarators for bicycles work process is divided into two stages: pressure handle handle (1) left end under a., semi-circle gear (3) rotates counterclockwise, path change-speed gearing B (5) turns clockwise, link with inner ring in flywheel A (6) outer ring, big footpath change-speed gearing B (9) turns clockwise, carrier gear A (10) rotates counterclockwise, carrier gear B (11) turns clockwise, carrier gear C (12) rotates counterclockwise, bevel gear B (15) rotates counterclockwise, bevel gear A (14) rotates forward, chain wheel (13) rotates forward, the flywheel C (17) on bicycle front axle is driven to rotate forward by roller chain (16), and then offer onward impulse；Meanwhile, carrier gear B (11) turns clockwise and drives big footpath change-speed gearing A (8) to rotate counterclockwise, flywheel B (7) inner ring does not links with outer ring, semi-circle gear (3) drives path change-speed gearing A (4) to turn clockwise, not linking with inner ring in flywheel B (7) outer ring, therefore this transmission process is unaffected.B. pressure handle handle (1) right-hand member is descended, semi-circle gear (3) turns clockwise, path change-speed gearing A (4) rotates counterclockwise, link with inner ring in flywheel B (7) outer ring, big footpath change-speed gearing A (8) rotates counterclockwise, carrier gear B (11) turns clockwise, carrier gear C (12) rotates counterclockwise, bevel gear B (15) rotates counterclockwise, bevel gear A (14) rotates forward, chain wheel (13) rotates forward, drives the flywheel C (17) on bicycle front axle rotate forward and then provide onward impulse by roller chain (16)；Simultaneously, carrier gear (11) turns clockwise and drives carrier gear A (10) to rotate counterclockwise, carrier gear A (10) drives big footpath change-speed gearing B (9) to turn clockwise, flywheel A (6) inner ring does not links with outer ring, semi-circle gear (3) turns clockwise and drives path change-speed gearing B (5) to rotate counterclockwise, not linking with inner ring in flywheel A (6) outer ring, therefore this transmission process is unaffected.

This Accelarators for bicycles and the adaptability of bicycle motive power system: during pressure handle handle (1), power input is installed on the flywheel C(17 of bicycle front axle instantly), separate driving with rear axle, do not affect motive power system function.Fixed plate (2) top is arranged on former handlebar crossbeam stage casing, and bottom is arranged on the crown portion of bicycle fore fork.Can twist left and right while the most lower pressure handle handle (1), normal direction of rotation uses.Handle is symmetrically installed pulley on (1), pulley base is rigidly connected with handle (1), fixed plate (2) is close to by pulley, and alternately during lower pressure handle handle (1), pulley is close to fixed plate (2) and is slided, and then more for stability when making left and right turn.
