Abstract
The utility model relates to a variable-speed gear, particularly a variable-speed gear of an electric booster tricycle. The utility model is provided with a box body 1, wherein, the front end of the box body 1 is provided with a shaft coupling 4 and a motor 5, the rear end of the box body 1 is provided with a chain wheel 6, and the inner part of the box body 1 is provided with a spline shaft 2 and a bridge piece shaft 3; the front end of the spline shaft 2 is connected with the shaft coupling 4, the rear end of the bridge piece shaft 3 is connected with the chain wheel 6, the spline shaft 2 is provided with gears 21, 22 and 23, and the bridge piece shaft 3 is provided with gears 31, 32 and 33; the box body 1 is also provided with a declutch shift shaft 7 which is connected with a declutch shift handle 8 and a declutch shift lever 9 which is provided with a shift fork 10. Due to the added variable-speed gear, an electric booster tricycle can run at different speeds in different cases with high safety, improved work efficiency and long service life.
Description
The utility model relates to a kind of transmission system, particularly the electric boosted tricycle transmission system.
Existing electric boosted tricycle, motor directly drives the rear axle rotation by sprocket wheel, chain, and three-wheel vehicle advances.But in the process of moving, can not speed governing, inefficiency.When load-carrying and climbing, speed obviously reduces, and motor load increases, and the battery cell discharge amount is big.Sometimes climbing does not become, and is sliding behind the three-wheel vehicle, can burn out the motor circuit.
The purpose of this utility model provides a kind of electric boosted tricycle transmission system that electric boosted tricycle is travelled according to the different situations speed change.
The purpose of this utility model is achieved in that the electric boosted tricycle transmission system, has casing 1, casing 1 front end has coupler 4 and motor 5, there is sprocket wheel 6 casing 1 rear end, castellated shaft 2 is arranged and the axle 3 of passing a bridge in the casing 1, castellated shaft 2 front end even couplings 4, the axle 3 rear end chain linking wheels 5 of passing a bridge, gear 21,22,23 is arranged on the castellated shaft 2, on the axle 3 of passing a bridge gear 31,32,33 is arranged.Declutch shift shaft 7 is arranged on the casing 1, be connected with shift fork handle 8 and shifting fork bar 9 on the declutch shift shaft 7, shift fork 10 is arranged on the shifting fork bar 9.
The utility model has the advantages that: owing to increased transmission system, electric boosted tricycle is travelled according to the different situations speed change, economical and practical, driving safety has improved work efficiency, has prolonged service life.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the cutaway view of Fig. 1.
The electric boosted tricycle transmission system has casing 1, castellated shaft 2 is arranged and the axle 3 of passing a bridge in the casing 1, coupler 4 is arranged before the castellated shaft 2, is motor 5 before the coupler 4, and there is sprocket wheel 6 axle 3 rear ends of passing a bridge, gear 21,22,23 is arranged on the castellated shaft 2, on the axle 3 of passing a bridge gear 31,32,33 is arranged.Declutch shift shaft 7 is arranged on the casing 1, be connected with shift fork handle 8 and shifting fork bar 9 on the declutch shift shaft 7, shift fork 10 is arranged on the shifting fork bar 9.
During the electric boosted tricycle cruising, motor 5 drives castellated shaft 2 and rotates, and drives the axle 3 of passing a bridge by gear 22 and gear 32 engagements and rotates, and sprocket wheel 6 rotates the three-wheel vehicle rear axle by chain, and three-wheel vehicle travels with 35km/h speed.
During heavy duty, stir shift fork handle 8, stir castellated shaft 2 by shift fork 10, make gear 21 and gear 31 engagements, three-wheel vehicle travels with 25km/h speed, during climbing, and gear 23 and gear 33 engagements, three-wheel vehicle travels with 13km/h speed.
