The utility model relates to the foot-operated three-wheel vehicle that power is provided by the people.
Existing three-wheel vehicle is to step on pedal repeatedly by the people, and rotates by the rear axle of a chain drive driving three-wheel vehicle, to obtain required tractive force and speed.Because sprocket wheel, chain be wearing and tearing constantly in use, when three-wheel vehicle advances, when especially heavy duty, upward slope, latch often occurs, take off chain and chain rupture.Also have, the three-wheel vehicle of chain gear has only a fixing transmitting ratio, and the cyclist can not be according to road with from the situation of body forces change speed and tractive force artificially, and during upward slope, if shortage of manpower or brake failure, car load then might fall back along the slope.During turning, can not realize differential, very easily occur overturning because the speed of left and right driving wheel is identical.
Task of the present utility model is: design a kind of foot-operated three-wheel vehicle, its driving system under any circumstance can both be effectively, work reliably; Three-wheel vehicle when advancing, the cyclist can be at any time change speed and tractive force easily; During upward slope, need not brake just can prevent falling back of three-wheel vehicle effectively; During turning, can realize reliably that left and right differential of taking turns travels.
The technical solution of the utility model is: hinged a pair of crank throw on its vehicle frame, the hinged stretcher of a certain radius of relative crank throw axis of revolution, driving system by driving the rotation of three-wheel vehicle rear axle changes the upper and lower motion of crank throw into rear axle rotatablely move, and realizes the left and right differential motion of taking turns by connecting speed-changing mechanism and the left and right clutch brake mechanism of taking turns of three-wheel vehicle.It is characterized in that: two crank throws (1) should be hinged separately, install, and pointed driving system is made up of steel cable driving system and shifting slide gear change speed gear box (3).Wherein, after steel cable (4) level of striding across is installed in fixed pulley (6) on the vehicle frame (5), two ends are installed on the both sides of vehicle frame (5) more respectively, and on the drum (7) of same horizontal axis, twine in the same way, and the two ends (8) of its steel cable (4) is separately fixed on the crank throw (1), two ratchets (2) are fixed on the sour jujube arbor wheel (9) with drum (7) coaxial line, and, inside face (10) by drum (7) is contained respectively, be equipped with between ratchet (2) and drum inside face (10) and make drum (7) and ratchet (2) one folk prescription also be the motion input shaft of shifting slide gear change speed gear box (3), retaining ratchet device (13) and conical clutch braking mechanism (23) are housed on the three-wheel vehicle rear axle (12) to ratchet (11) ratchet shaft (9) that rotates.When the cyclist steps on left-hand tread plate (20), the steel cable (4) that is fixed on the crank throw (1) makes drum (7) rotate along direction (21), by ratchet (11) ratchet (2) and ratchet shaft (9) are rotated with drum (7) one direction, steel cable (4) is by fixed pulley (6), after drum (7) break-in, right-hand tread plate (20) is risen, since can only folk prescription between drum (7) and ratchet (2) to transmitting movement, so, when drum (7) under the effect of steel cable (4), when direction (22) is rotated, ratchet (2) then rotates along direction (21) with ratchet shaft (9), ratchet (11) is inoperative, can not move interference, when left-hand tread plate (20) end position of down stepping on, right-hand tread plate (20) also rises to end position.When stepping on right-hand tread plate (20) again, in like manner, make that ratchet shaft is equidirectional to be rotated further, left-hand tread plate (20) rises again, so circulation, the equidirectional all the time rotation of ratchet shaft (9), the motion input shifting slide gear change speed gear box (3) of ratchet shaft (9) by operating mechanism, is selected different ratios of number of teeth, be that exportable different rotating speed and tractive force are to rear axle (12), to drive the three-wheel vehicle motion.The retaining ratchet device of installing on the three-wheel vehicle rear axle (13), the principle of also having utilized the ratchet device unidirectional delivery to move can prevent effectively that the three-wheel vehicle upward slope from falling back.During right-hand corner, output shaft of gear-box (12) and right driving wheel (24) shape clutch brake mechanism of bonded assembly class (23) are broken away from, simultaneously, right wheel is slowed down become flower wheel, revolver (24) still keeps original speed for driving wheel, this has just realized the left and right differential motion of taking turns, and three-wheel vehicle is right-hand turning easily just also.In like manner, output shaft of gear-box (12) and left driving wheel (24) bonded assembly conical clutch braking mechanism (23) are broken away from, and left driving wheel (24) is slowed down to flower wheel, also just realized the differential motion of turnon left.
Further improvement of the utility model is also to be provided with steel cable tension wheel (16) between crank throw (1) and drum (7), regulate nervous wheel (16) at diverse location, both the scalable tensile force guaranteed that drum (7) and steel cable (4) failure-free are synchronized with the movement, and can regulate the initial position of crank throw (1) again.
Shortcomings such as the latch that adopts the utility model to eliminate to occur in the chain gear, chain dropping type chain rupture, owing to increased speed-changing mechanism, control rate and tractive force easily, retaining ratchet device can prevent effectively that three-wheel vehicle from going up a slope and fall back; Differential motion when the conical clutch braking mechanism on the rear axle can be realized the three-wheel vehicle turning reliably.
