Abstract
The utility model relates to a laborsaving and chainless transmission gear for bicycles, which is technically characterized in that a centre shaft is arranged inside a bearing of a gearbox body, and a front drive gear is fixed to a geared sleeve and is meshed with two guide gears which are inlaid and sheathed on a guide shaft. The front drive gear is provided with a bevel gear. The bevel gear is meshed with a cone gear inside the gearbox. A shaft lever of the cone gear is matched with a cross shaft. The back cone gear at the cross shaft end is meshed with a back driving cone gear which is arranged on a back shaft. A flywheel is driven by the back driving cone gear to move forward. The laborsaving and chainless transmission gear for bicycles has the advantages of simple structure, convenient installation and operation, low manufacture cost, big transmission output torque, laborsaving climbing, high speed, etc.
Description
The utility model belongs to technical field of bicycles, particularly a kind of labour saving chainless driving device for bicycle.
Traditional bicycle type of drive adopts the wheel chain structure, and this bicycle grade climbing performance is relatively poor, and it is painstaking to ride.
The purpose of this utility model is to change traditional type of drive, and a kind of labour saving chainless driving device for bicycle is provided, and this device has the advantages that rotating torque is little, laborsaving, speed is fast, grade climbing performance is higher.
The purpose of this utility model is achieved through the following technical solutions: labour saving chainless driving device for bicycle is made up of change speed gear box, axis, the axis of guide, gear transmission structure, wherein axis is installed in the bearing of gearbox body, driving gear is fixed on an end of axis, and with the axis of guide on leading to gear mesh, geared sleeve is by bearing and axis bearing fit, front drive gear is fixed on the geared sleeve, and with the axis of guide on two guide gears engagements of edge cover.Front drive gear has a bevel gear, garden finishing bevel gear cuter engagement in bevel gear and the change speed gear box, garden finishing bevel gear cuter axostylus axostyle cooperates with center cross, and the back garden finishing bevel gear cuter of cross axle head and the rear drive garden finishing bevel gear cuter engagement that is installed on the rear axle drive freewheel in forward motion by rear drive garden finishing bevel gear cuter.
The utlity model has relatively simple for structure, easy to install, manufacturing cost is lower, the transmission output torque is big, climbing is laborsaving, speed is fast.
In conjunction with the accompanying drawings structure of the present utility model is described further.
Fig. 1 is the utility model structural principle section-drawing.
Fig. 2 is the utility model rear drive configuration scheme drawing.
Fig. 1, the 2nd, embodiment of the present utility model.
With reference to Fig. 1,2, labour saving chainless driving device for bicycle is by change speed gear box 1, axis 9, the axis of guide 5, gear transmission structure is formed, wherein axis 9 is installed in the casing bearing 2 of change speed gear box 1, driving gear 10 is fixed on an end of axis 9, geared sleeve 9 is by bearing 22 and axis 9 bearing fits, front drive gear 12,11 are fixed on the geared sleeve 9, with front drive gear 12, the other end of 11 one is umbrella teeth 13, the axis of guide 5 devices are in the bearing 21 on change speed gear box 1 top, guide gear 3 is fixed on an end of the axis of guide 5, mesh to gear 3 with leading, also be fixed with guide gear 6 on the axis of guide 5,7, guide gear 6 or 7 and front drive gear 12 or 11 the engagement, sleeve pipe 4 is sleeved on the other end of the axis of guide 5, spacing guide gear 7, the umbrella tooth 13 of front drive gear and garden finishing bevel gear cuter 14 engagements that are installed on change speed gear box 1 bottom by bearing 19, the axostylus axostyle of garden finishing bevel gear cuter 14 cooperates with center cross 15, the garden finishing bevel gear cuter 18 of center cross 15 ends and rear drive garden finishing bevel gear cuter 17 engagements that are installed on the rear axle 20, rear drive garden finishing bevel gear cuter 17 cooperates with flywheel 16 on being installed on rear axle 20, drives flywheels 16 by rear drive garden awl tooth 17 and rotates forward.
