Abstract
The utility model relates to a reciprocating driven pedal cycle, comprising wheels, a frame, a reciprocating driving mechanism, a main driving chain wheel, a driving chain and a rear driving flywheel, is characterized in that a clutch mechanism is provided between the main driving chain wheel and the rear driving flywheel. The utility model alters the circular motion of a running pedal cycle to reciprocating motion, reducing the blank area of the driver's force application and especially making the backing easy and convenient; the foot rest lever will not sway following the backing, so the failure rate is reduced. The utility model applies to all prior manpower pedal cycles, in particular to three-wheel manpower pedal cycles.
Description
Technical field:
The utility model relates to a kind of bicycle, especially a kind of bicycle of reciprocating type driving.
Background technology:
The pedal of present bicycle is a circular movement, when pedal the highs and lows of circumference and near the time, bicyclist's both feet just are difficult to firmly, Gu and cause a clear area of exerting oneself, especially need in the firmly bigger bicycle like this at three-wheel vehicle, this clear area of exerting oneself is just fairly obvious, make troubles to the user, and some present reciprocating type bicycles, because the deficiency in its design, when bicycle is moveed backward, foot-driven lever is swung up and down with reversing, be very easy to damage driver train.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can reduce the bicyclist clear area of exerting oneself, and is easy and convenient when especially moveing backward, and can not make foot-driven lever with reversing swing, the reciprocating type driving bicycle that fault is few.
The utility model comprises wheel, vehicle frame, reciprocating drive mechanism, main drive sprocket, chain drive-belt and rear drive flywheel, it is characterized in that being provided with engaging and disengaging gear between main drive sprocket and the rear drive flywheel, this engaging and disengaging gear comprises two driving chain wheels that link to each other with the rear drive flywheel with main drive sprocket respectively, one in two driving chain wheels is fixed on the axle, another driving chain wheel then is located at one can be on the axle sleeve that rotates on this, described axle sleeve is provided with axial slide rail, axle sleeve has outward and is provided with the slideway that coincide with the axle sleeve slide rail, and can be along the clutch slider of axle sleeve slide rail direction slip, the slide block middle part is provided with clutch yoke, by the end of being fixed in driving chain wheel one end on the axle protruding engagement post is arranged, be fixed with drive block on the axle with described engagement post ingear pit.
Circular movement changed crank motion into when the utility model was ridden bicycle, reduced the clear area that the bicyclist exerts oneself, easy and convenient when especially moveing backward, foot-driven lever is swung with reversing, fault rate reduces, be applicable to present various manpower bicycles, be particularly suitable for the manpower bicycle of three-wheel.
Description of drawings:
Fig. 1 is the utility model embodiment 1 main structural representation of looking.
Fig. 2 is the structural representation of clutch slider.
Fig. 3 is the structural representation with clutch slider engagement post ingear drive block.
The utility model comprises wheel, vehicle frame, reciprocating drive mechanism, main drive sprocket 4, chain drive-belt 10 and rear drive flywheel, reciprocating drive mechanism is by foot-driven lever 1, unidirectional flywheel 5, foot-driven lever return pulley 3 and return rope 2 are formed, between main drive sprocket 4 and rear drive flywheel, be provided with engaging and disengaging gear, this engaging and disengaging gear comprises two driving chain wheels 9 that link to each other with the rear drive flywheel with main drive sprocket 4 respectively, one in two driving chain wheels is fixed on the axle 16, another driving chain wheel then is located at one can be on the axle sleeve 17 that rotates on this, described axle sleeve 17 is provided with axial slide rail 15, axle sleeve 17 is outer to be had and is provided with the slideway that coincide with axle sleeve slide rail 15, and can be along the clutch slider 18 of axle sleeve slide rail direction slip, the slide block middle part is provided with clutch yoke 8, clutch yoke 8 is provided with pull back spring 7 and control backguy 6, the shift fork head of clutch yoke 8 places in the fork slot 14 on the clutch slider 18, by the end of being fixed in driving chain wheel one end on the axle 16 protruding engagement post 13 is arranged, be fixed with drive block 11 on the axle with described engagement post ingear pit 12.
The specific embodiment:
With reference to accompanying drawing, structural representation for Cui embodiment of the present utility model, comprise wheel, vehicle frame, reciprocating drive mechanism, main drive sprocket, chain drive-belt and rear drive flywheel, reciprocating drive mechanism is made up of foot-driven lever, unidirectional flywheel, foot-driven lever return pulley and return rope, be provided with engaging and disengaging gear between main drive sprocket and rear drive flywheel, two driving chain wheels of engaging and disengaging gear divide with chain and are connected with the rear drive flywheel with main drive sprocket.
