Description

Two movable sprocket drive-type Tricycles

Technical field: the utility model relates to a kind of novel three-wheeled bicycle, particularly a kind of pair of movable sprocket drive-type Tricycle.

Background technology: existing tricycle, generally be to adopt to be seated to ride, power driven also is to trample pedal with both feet around axis, changes flywheel by the sprocket wheel on the crank by the chain band tricycle is moved ahead, and the utility model is that a kind of mode of riding and structure that is different from this will be provided.

Summary of the invention: the purpose of this utility model provides a kind of new mode of riding---and stand and ride, can a pin trample pedal and make it to move ahead, also can trample pedal by two castor streams, the two movable sprocket drive-type Tricycles that make it to move ahead.The technical issues that need to address are: provide two covers to utilize the movable sprocket driver train of assembly pulley principle.The technical solution of the utility model is: two movable sprocket drive-type Tricycles, comprise vehicle body, handlebar, front-wheel, two trailing wheels and two cover movable sprocket driver trains etc., it is characterized in that: two cover movable sprocket driver trains are arranged on the rear portion of vehicle body, and two cover movable sprocket driver trains comprise two treadles, two stands, two chains, two pedals, two extension springs, two flywheels and two movable sprockets; About dividing, two stands is fixed on the both sides of body tail, the middle part of two treadles by about do movable the connection with left and right sides support respectively, one end of two treadles is installed two pedals respectively, the other end of two treadles is installed two movable sprockets respectively, inboard at two trailing wheel centers is installed two flywheels respectively, one end of two chains by about be installed in the both sides of body tail respectively, and respectively on two movable sprockets and two flywheels of two trailing wheel inboards, the other end of two chains connects an end of two extension springs respectively, and the other end of two extension springs connects the both sides of vehicle body below respectively.

The beneficial effects of the utility model are: having changed is seated rides the mode of tricycle, and any pin of bipod this car of can both riding also can be trampled this car of riding by bipod in turn, has simple structure, the random advantage such as strong of riding.

Scheme drawing when Fig. 4 lifts for the utility model right crus of diaphragm

Among the figure: 1---vehicle body, 2---handlebar, 3---front-wheel, 4---trailing wheel, 5---the movable sprocket driver train; 5a---treadle, 5b---support, 5c---chain, 5d---pedal, 5e---extension spring, 5f---flywheel, 5g---movable sprocket.

The specific embodiment: with reference to Fig. 1,2,3,4, two movable sprocket drive-type Tricycles, comprise that vehicle body 1, handlebar 2, front-wheel 3, two trailing wheels 4, two movable sprocket driver trains, 5, two movable sprocket driver trains 5 comprise two treadle 5a, two stands 5b, two chain 5c, two pedal 5d, two extension spring 5e, two flywheel 5f and two movable sprocket 5g; About dividing, two stands 5b is fixed on the both sides at vehicle body 1 rear portion, the middle part of two treadle 5a by about do movable the connection with left and right sides support 5b respectively, the end of two treadle 5a is installed two pedal 5d respectively, the other end of two treadle 5a is installed two movable sprocket 5g respectively, inboard at two trailing wheels, 4 centers is installed two flywheel 5f respectively, the end of two chain 5c by about be installed in the both sides at vehicle body 1 rear portion respectively, and respectively on the two movable sprocket 5g and two flywheel 5f of two trailing wheels, 4 inboards, the other end of two chain 5c connects the end of two extension spring 5e respectively, and the other end of two extension spring 5e connects vehicle body 1 below respectively.In the time will riding two movable sprocket drive-type Tricycle, right crus of diaphragm is trampled right pedal 5d, the other end of right treadle 5a can be with right movable sprocket 5g to upwarp, moving on the right movable sprocket 5g can be to move two-fold apart from pull right chain 5c on it, make right chain 5c drive right flywheel 5f twirl, and make off hind wheel 4 twirl, make two movable sprocket drive-type Tricycle fast driving (referring to Fig. 2); Left foot is stepped on left foot again pedal 5d, the other end of left side treadle 5a can be with left movable sprocket 5g to upwarp, moving on the movable sprocket 5g of a left side can be to move two-fold apart from pull left chain 5c on it, make left chain 5c drive left flywheel 5f twirl, and make left rear wheel 4 quicken to rotate, make two movable sprocket drive-type Tricycles quicken to move ahead (referring to Fig. 3); When on lift right crus of diaphragm, under the effect of right extension spring 5e, pulling back of right chain 5c can make right treadle 5a be with homing at once such as right pedal 5d, trample right pedal 5d once more for right crus of diaphragm and done necessary preparation (referring to Fig. 4), right crus of diaphragm continues to trample right pedal 5d, makes two movable sprocket drive-type Tricycles continue to move ahead fast; Equally, when lifting left foot, under the effect of Zola's spring 5e, left side treadle 5a inconjunction with left foot is pedaled homing at once such as 5d, trampling left foot once more for left foot pedals 5d and has done necessary preparation (referring to Fig. 2), so, left and right sides bipod is trampled left and right sides pedal 5d in turn, and two movable sprocket drive-type Tricycles are moved ahead continuously and healthily.
