Description

Pedal three-wheel sport car

[technical field]

The utility model relates to the bicycle field, specifically a kind of pedal three-wheel sport car.

[background technology]

As everyone knows, existing three-wheel vehicle drives the front and back wheel motion by big miniature gears by chain and rotating mechanism, but can not speed change, and speed is unhappy like this, and waste is physical easily.

[summary of the invention]

The purpose of this utility model designs a kind of three-wheel sport car of novel structure, by moving of cliding gear, changes the speed change of three-wheel vehicle transmission, saves muscle power, satisfies the daily life needs, enriches perambulator market.

For achieving the above object, design a kind of pedal three-wheel sport car, comprise halter front-wheel combination (1), main (2), turriform gear cluster (3), carrier gear (4), rear axle gear (5), flywheel (6), gear case (7), trailing wheel (8), mudwing (9), governing screw (10), back bracket (11), regulate seat cushion (12), sliding tray (13), left and right sides ratchet (14), ratchet hook (15), pull back spring (16), left and right sides pedal stake (17), left and right sides pedal (18), chain bar (19), pull back spring (20), chain lever pin (21), chain bar groove compositions such as (22) is characterized in that drive transmission device: a. main (2), turriform gear cluster (3), carrier gear (4), rear axle gear (5), parallel to each other and the engagement of flywheel (6); B. the tower gear cluster is made up of 2 gears of size, can slide along self axis by the front and back gear, changes the transmitting ratio between main (2) and the carrier gear (4); C. pedal (18) connection chain bar (19), chain linkage in the gear case (7) connects the ratchet hook, the ratchet hook connects ratchet (14), make main (2) main (2) with coaxial ratchet, turriform gear cluster (3), carrier gear (4), rear axle gear (5), parallel to each other and the engagement of flywheel (6), main (2) connects the miniature gears of turriform gear cluster (3), coaxial big gear wheel by turriform gear cluster (3) connects carrier gear (4) again, can slide along self axis by the front and back gear, change the transmitting ratio between main (2) and the carrier gear (4), last carrier gear (4) connects rear axle gear (5) and coaxial with it flywheel (6) and trailing wheel (8) again.

The utility model is compared with prior art, mainly be to use external force to drive first group of gear by pedal, drive the multiplying power of quickening second group of cone pulley raising revolution through first group, more than as drive the 3rd group again and make the 3rd group to drive carrier gear with several times rotating speed, make it land wheel and flywheel twirl with the same axle of carrier gear, as with per 40 times/minute pedals, it can walk 10.36 meters, as just walking 15.5 meters with per 60 times/minute, can walk 20.7 meters with per 80 times/minute, just can on average walk 25.4 meters with per 100 times/minute, can walk 31 meters with per 120 times/meter, it is 17.5 meters/minute that five kinds of speed drive sport cars average velociity that advances can be arranged, and in the process of pedal, can be interrupted pedal by the coaxial flywheel of land wheel on behalf of serving, can save certain amount of exercise has the rest halt of interruption, regain one's strength, this car can be played for about 4 years old to 10 years old, because the seat can be adjusted highly for different ages child's needs, and the shelves seat of seat cushion is partly much longer than bicycle, make a little bit smaller children also can seat steady, for sport car can safety in the process of running, stop before, on the front-wheel top is that the pressure lock is equipped with in the front fork bottom, because the braking potential of this lock is stronger than general pincers lock, and left and right sides brake lever is the same lock of stopping when holding with a firm grip, holds the power deficiency to satisfy the child, so braking force is very high.The anti-sheath of wounding is housed in case the child runs into obstacle by bike the time jumps on crossbeam and hindering on the handlebar crossbeam.The weight of car load is no more than 7KG, 0.71 meter * 0.45 meter * 0.4 meter of the overall dimensions of sport car (length), crack, ground height between car bottom plate and the ground is 0.22 meter, and base plate and seat height are 0.2 meter, the highlyest transfers to 0.3 meter high, height between ground and seat cushion is 0.42 meter, the highlyest can be 0.52 meter, this car firm and durable, steadily safety, light and flexible, center of gravity are low, and very suitable child plays and takes exercises the racing bicycle of holding between the child.Invest for a short time, cost is low, is worthy of promotion and application.
