Abstract
The utility model pertains to a tricycle, more particularly, a front-wheel drive tricycle via the skip step, comprising a saddle, a front fork, a front wheel, the rear wheels, a bodywork, an axis, a crank, a wheel plate, a chain, a flywheel and the pedals so as to form the drive unit which is characterized in that the said drive unit is the front-wheel drive unit arranged on the front fork; the permanent connection is made among the front-wheel drive unit, the stand and the stiffener. One end of the stand is connected with the front fork and the front axle, while the end thereof is copulated with the lower end of the stiffener and fixed with the axle, the wheel plate, the crank and the pedal of the drive unit. The wheel plate of the drive unit is connected with the flywheel drive via the chain. Such flywheel drive is fixed on the front axis. The upper part of the stiffener is connected with the shoulder of the front fork. This utility model has the advantages that the riding posture is changed, so that the partial straining is decentralized to the entire body. Therefore, safety, coziness, small resistance force and fast speed are achieved.
Description
Technical field
The utility model belongs to three-wheel vehicle, relates in particular to a kind of f-w-d three-wheel vehicle that scrunches mode.
Background technology
Now, three-wheel vehicle is that the actuating device that five-way connects axis, crank and wheel disc and pedal composition is set in the middle part of vehicle frame, the people is sitting on the saddle that is fixed in central frame beam position higher position, get rid of the pedal tap pedal with vertical posture, drive the flywheel that is provided with on the rear axle by chain and adopt back-wheel drive, vehicle is advanced.Because the rider body erect, car is subjected to wind in advancing resistance is big, and running speed is slow, and it is big to consume one's strength.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of small portable quick, laborsaving, safe f-w-d three-wheel vehicle.
The utility model for achieving the above object, by the following technical solutions: a kind of f-w-d three-wheel vehicle, comprise saddle, front fork, front-wheel, trailing wheel, saddle, vehicle frame, by axle, crank, wheel disc, chain, the actuating device that flywheel and pedal are formed, it is characterized in that: described actuating device is the front-wheel drive that is arranged on the front fork, front-wheel drive is captiveed joint with stirrup with support, described support one end is connected with front fork and front axle, its other end and stirrup lower end join and with actuating device the axle, wheel disc, crank, and the pedal assembly is affixed, the wheel disc of actuating device is in transmission connection by chain and the flywheel that is fixed on the front axle, and the upper end of described stirrup is connected with the front fork shoulder.
The wheelspan of described two trailing wheels is 450～550mm; The wheelbase of front axle, rear axle is 700～1100mm, and the setting of rear axle makes the parallel or inwardly symmetry inclination of upper limb of two trailing wheels horizontal by 0～15 degree angle.
Described saddle can be regulated front and back on vehicle frame, and saddle height is apart from ground 450～650mm.
Before and after being provided with, described saddle arranges two on vehicle frame.
The beneficial effects of the utility model: change the attitude of riding, the part firmly can be distributed to whole body firmly.Safe, comfortable, resistance is little, speed is fast.
