Description

The car but the inclination three-wheel with two rear drive sprockets is marked time

Technical field:

But the present invention relates to a kind of inclination three-wheel car of marking time with two rear drive sprockets.

Background technology:

Along with the fast development in city, the contradiction of the vehicle and path resource becomes increasingly conspicuous, and particularly the big and medium-sized cities traffic jam issue is very serious.Developing public transport is the effective way that addresses this problem, but traffic network limited coverage area, need the short distance traffic instrument between passenger and the traffic website,, when the traffic route two ends all need the vehicle, be difficult to meet the demands because bicycle can't carry; Folding bicycle complex operation, volume after folding are still bigger, and portability is relatively poor; Kickboard Scooter is folding convenient, and volume is little, be easy to carry, but major part is two wheel constructions, does not possess foot-operated function, the riding stability and handling relatively poor of driving.

Summary of the invention:

This is the solution of the portable vehicle of a kind of short distance, has improved the portability of vehicle with the similar foldable structure of Kickboard Scooter; A steering front wheel, two tricycle structures that drive trailing wheel make vehicle ' more stable; Driver's forward stand on the car of marking time, sole steps down on two fixed pedestals, heel is put on two Active foot plates, both feet are done the motion of marking time, the weight of health drives Active foot plate by heel, drive two trailing wheels by the drive disk assemblies such as rack drives gear that have the one-way locking function on the Active foot plate, driver's body action amplitude is less, propulsive effort is balanced, and traveling comfort is higher; Adopt parallelogram pivotally connected frame structure, make two trailing wheels and handlebar keeping parallelism, health and handlebar inclination can keep balance when turning, and have higher steering flexibility.

Owing to occupy little space after the present invention is folding, to be convenient to carry, folding storing up rapidly can be used as replenishing of urban transportation tool, improves traffic efficiency, also can be used as the amusement and recreation fitness tool simultaneously.

The specific embodiment:

The three-wheel of the telling car 1 of marking time mainly comprises parts such as vehicle frame, handlebar, wheel.Vehicle frame is made up of two bogie side frames 17 and a middle frame 18, and hinged by two support boxed rods 15 (a, b) and two support lower links 16 (a, b), and frame 18 remains parallel with bogie side frame 17 in making.Wherein connecting rod 15 (a) and connecting rod 15 (b) make connecting rod 15 (a) and connecting rod 15 (b) form an integral body by being rigidly connected through middle frame in-to-in tubing string 14.Two drive trailing wheels 22 and are fixed on two bogie side frames 17 by hind axle 23 respectively, and the parallelogram sturcutre by support, make two wheels remain parallel with vehicle frame.

Two Active foot plates 20 pass through pedal shaft 21 independent stationary on two bogie side frames 17, and can in certain angle, rotate, steel sheet spring 33 1 ends are fixed on the bogie side frame 17, and Active foot plate 20 is formed elastic force upwards, make Active foot plate 20 can forward the top fast to there not being external force to do the time spent.

One end of driving rack 24 has two strip shape locking inclined holes 26, cooperates with two guideposts 25 that are fixed on Active foot plate 20 ends, and driving rack 24 can slide in the end of Active foot plate 20 by locking inclined hole 26.U-shaped bottom one end of U-shaped locking spring 27 is fixed on the bogie side frame 17, and U-shaped opening one end has certain gripping power to tooth bar 24.When Active foot plate 20 moved downward, under the combined action of inclined-plane of locking inclined hole 26 and U-shaped locking spring 27 resistances, tooth bar 24 outwards slided, and cooperates with transmission gear 28, will pass to transmission gear 28 to Active foot plate 20 downward pedal forcees; Otherwise driving rack 24 inwardly slides, and breaks away from transmission gear 28, realizes the one-way locking function.

Transmission gear 28 is fixed on the bogie side frame by sprocket shaft 30 with hinge wheel 29, on hinge wheel 29 and minor sprocket 32, chain 31 is installed, minor sprocket 32 is fixed on the hind axle 23, hinge wheel 29 by chain 31 with transmission of power to minor sprocket 32, and drive trailing wheel 23 and drive the car of marking time and move ahead.

Handlebar folding rack 10 is the U-shaped structure, and an end is fixed on the handlebar axle sleeve 9, and on the frame 18, there was a strip shape support fixed orifice 11 that runs through both sides at the middle part of folding rack 10 during U-shaped opening one end was fixed on by support anchor shaft 13; On the middle frame guide securement hole 19 is arranged, the groove at two ends plays the fixation that handlebar is folding and open, in the support fixed orifice 11 and the guide securement hole 19 on the middle frame 18 of anchor shaft in the folding latching device 12 of similar Kickboard Scooter on the support 10, after unclamping latching device 12, handlebar folding rack 10 can drive handlebar and fold downwards or upwards open, after the anchor shaft in the latching device 12 moves to the two ends in middle frame guide securement hole 19, can move the locking spanner on the latching device 12, handlebar folding rack 10 is fixed on the middle frame 18, the car of marking time is stayed open or folding state.

The handlebar stretching structure is identical with Kickboard Scooter.Handlebar expansion link 6 is installed in the handlebar telescopic tube 8, there is an anchor fitting 7 on the top of telescopic tube 8, when needing to fold, unclamp the back-up wrench on the anchor fitting 7 earlier, handlebar expansion link 6 is inserted in the handlebar telescopic tube 8, move anchor fitting 7 to locked position again, otherwise vertical handgrip 6 can be pulled out and fixed.

Handlebar is made up of fixed part 2 and telescopic section 5, but telescopic section 5 sleeves and lock telescopic location to the similar Spring Card post of folding fixed form by one with Kickboard Scooter in fixed part 2.

The car of marking time is provided with the front-wheel brake, brake sneek 3 is fixed on the handlebar fixed part 2 by brake axle 4, pinching brake sneek 3 makes it to rotate around brake axle 4 when brake, and drive is fixed on the brake cable on the brake sneek 3, brake cable is connected with brake gear on being fixed on front-wheel support by handlebar expansion link 6 and telescopic tube 8, realizes the brake purpose.
