Description

Two driving folding tricycles

The utility model relates to a kind of three-wheel vehicle, particularly a kind of two folding tricycles that drive.

At present and since three-wheel vehicle, loading manned with it all can, characteristics such as easy to use be subjected to liking of ordinary consumer, but known three-wheel vehicle volume are big, center of gravity is high, the speed of a motor vehicle is slow, safety factor is low, have influenced its sales volume again.

The utility model purpose provides a kind of two folding tricycle that drives, and the little speed of a motor vehicle of its volume is fast, takes advantage of seat comfortable, the safety factor height.

The two folding tricycles that drive of the utility model design-calculated comprise a front-wheel as wheel flutter, two trailing wheels as drive wheel, insert before being connected with in turn on the front-wheel, bogie truck and bearing circle, bogie truck is provided with slide, slide is fixed on the vehicle frame front end, slide is provided with sliding thick stick and downslide thick stick, also is provided with lock seat and brake lever under the vehicle frame upper saddle, and institute's bonded assembly brake cable one is through to the trailing wheel place; The vehicle frame rear portion is connected with folding following and lazyback by rotating shaft, on the following seat spring is housed, and following seat front end is provided with handle, in the lazyback lower end, on promptly following the plane cushion is housed; All captive joint with trailing wheel in vehicle frame rear portion, the described left and right sides, Flywheel disc is housed on the hind axle, be provided with drawstring in the long mouth of Flywheel disc, the drawstring other end is fixed on the accelerator with stagnant band, accelerator is installed on the accelerator seat, the accelerator seat is fixed on an end that has pedal of rocking arm, and the other end of rocking arm is fixed on the rocker stand on the vehicle frame.

The two folding tricycles that drive of the utility model design-calculated can also comprise that with following former rear center line be that the center is folding.

The two folding tricycles that drive of the utility model design-calculated can also comprise soft bicycle shed.

The two driving of the utility model design-calculated folding tricycle has 1, low center of gravity is anti-skidding prevents turning over, and brake is reliable; 2, peripheral double-disk vehicle frame, anticollision can fold; 3, deposit after folding that to stablize volume little; 4, have roomy spring seat cushion and backrest, take advantage of the comfortable shock-absorbing of seat good; 5, drive mechanism is simple, repairs easily, and it is fast to pedal the laborsaving speed of a motor vehicle; 6, the profile garden is sliding, and anti-collision is scraped; 7, turn radius is little, maneuverability; 8, it is sun-proof, rainproof bicycle shed to be housed; 9, stop conveniently in the way, start characteristics such as fast.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is two left side, the folding three-wheeled vehicle carriage rear portion structural representations that drive of the utility model design-calculated;

Fig. 2 for the A of accompanying drawing 1 to structural representation (comprising front-wheel);

Transmission and the variable-speed motor structural representation of Fig. 3 for amplifying.

Number in the figure 1 is a vehicle frame, and 2 is slide, and 3 is last sliding thick stick, and 4 are the downslide thick stick, 5 are following, and 6 are handle, and 7 is rocker stand, and 8 is rocking arm, 9 is the accelerator seat, and 10 is accelerator, and 11 is pedal, 12 is bogie truck, and 13 is bearing circle, and 14 is preceding inserting, 15 is front-wheel, and 16 is trailing wheel, and 17 is cushion, 18 is Flywheel disc, and 19 is the lock seat, and 20 is brake lever, 21 is frame, and 22 is soft canopy, and 23 is pincerlike lock, 24 is brake cable, and 25 is end cap, and 26 is reed, 27 is drawstring, and 28 are the band that stagnates, and 29 is the speed change thick stick, 30 is the speed change spring, and 31 is bolt, and 32 is rear axle, 33 is afterburning circle, and 34 is backrest, and 35 are a following extension spring, 36 are the sliding thick stick position signal of folding back, and 37 are folding aftercarriage line of centers, and 38 for putting signal in the seat down in folding back.

As shown in the figure, the utility model is a tricycle structure, and drive mechanism is reciprocating type.Folding exsert biplate symmetric form vehicle frame, vehicle seat is equipped with extension spring, and lazyback has the sponge cushion again, and vehicle frame is equipped with soft bicycle shed.

Vehicle frame 1 usefulness rigid material is made.The vehicle frame front end has been manufactured slide 2, and slide is installed on the bogie truck 12, inserts on 14 before bogie truck is installed in, and preceding slotting lower end is installed on the front-wheel.Preceding inserting in the standpipe is fixed with bearing circle 13, and steering wheel rotation can be finished turning to of car body on the go.The vehicle frame rear portion is equipped with what rotating shaft connected and is done following 5 that amounts to motion upwards, backward, backrest 34, and following seat is equipped with 35 some of extension springs, with backrest cushion 17 is housed together, and human body improves the comfort property of taking advantage of seat to the impulsive force of vehicle frame in being used for reducing to drive a vehicle.With downslide thick stick 4 is the axle center, promotes bogie truck forward and makes sliding thick stick 3 two ends align the slide hole, upwards lifts handle 6, and seat and backrest are made progress, amount to backward, drive left and right sides vehicle frame along the slide down thick stick to bogie pivot center move finish folding.After folding, the car load volume reduces half, makes storage area less than two wheel bicycle storage area.And after folding, in stable condition, move freely, lock conveniently.

Vehicle frame rear portion, the left and right sides is fixed with hind axle 32, trailing wheel 16 is installed on the hind axle, on the axle skin Flywheel disc 18 is installed, in the long mouth of Flywheel disc drawstring 27 is installed, the drawstring other end is fixed on the accelerator 10 with stagnant band 28, and accelerator is installed on the accelerator seat 9, and the accelerator seat is fixed on the rocking arm 8; rocking arm is installed on the rocker stand 7, and rocker stand is fixed on the vehicle frame.Pedal and shake arm bottom pedal 11, rocking arm is swung forward, drives the drawstring on the Flywheel disc, and trailing wheel is rolled forward; Rocking arm unclamps drawstring when swinging backward, drawstring is the wraparound Flywheel disc under the effect of reseting leaf 26.Load onto or take off afterburning circle 33, changed the diameter of drawstring on the Flywheel disc, just changed the size of tension on trailing wheel of drawstring, thereby realized adding, subtracting the effect of power.Change the position that accelerator speed change thick stick is positioned at long mouth on the accelerator seat, just changed the position of drawstring force position on rocking arm, under the situation that the rocking arm movement angle equates, the drawstring movement length changes, thereby realizes the function of speed change.Another effect of accelerator is the variation of moment in the rocking arm motion.
