The specific embodiment

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Tu

As shown in Figure 1-Figure 3: it comprises, and handlebar, vehicle frame, vehicle seat, brake, pin are stared at, car turns, front and rear wheel and battery, it is characterized in that: two front-wheels 1 and a trailing wheel 2, and foresteerage gear is arranged and fixing braking mechanism on handlebar in the center fixed of two front-wheels 1.Front-wheel 1 is two 12 " wheel, trailing wheel 2 is 18 " wheel, front-wheel 1 has only 1050 millimeters with trailing wheel 2 centre distances, and the center width of two front-wheels 1 is that 480 millimeters stand outs with handlebar are few, and the vehicle body short weight heart is low, good stability; As Fig. 4, shown in Figure 5: foresteerage gear is by two levers 3 at an angle to each other, universal bearing 4, pull bar 5, spindle arm 6 and handlebar front fork 7 constitute, one end of handlebar front fork 7 is connected with handlebar by stem 8, as shown in Figure 8: the other end of handlebar front fork 7 is threaded, its end is welded with the tetragonal prism 9 concentric with handlebar front fork 7, one end of tetragonal prism 9 stretches out is with externally threaded little axle, one end of two levers 3 is inserted on the tetragonal prism 9, the angle that two levers are 3 is 58 ° (being generally 50 °-80 °) and use nut screwing clamping, the other end is connected with pull bar 5 respectively by universal bearing 4, two pull bars 5 are staggered form, the other end of pull bar 5 is fixed on the spindle arm 6 of front-wheel 1, spindle arm 6 Yong Gang Guan Wei become the U font, aperture is flattened and opens at the two ends of U font, then, spindle arm 6 usefulness nuts are captiveed joint with front wheel spindle, the front fork overcoat 17 of two front-wheels 1 and hold-down arm 18 solder togethers as shown in Figure 8, the other end of hold-down arm 18 is welded in the both sides of the front fork overcoat 17 of handlebar front fork 7 outsides, for convenient transportation front fork overcoat 17 and hold-down arm 18 are split type, the side's of having tooth 19 respectively on it, during transportation, the square tooth 19 of interlock staggered to change an angle or take off singly put, then two hold-down arms 18 can parallelly be put into case with front fork overcoat 17, during use square tooth 19 are locked; As shown in Figure 5: when walking is turned, rotate handlebar and drive two front-wheel 1 rotational angles, at this moment, the big hard-over of front-wheel 1 corner of the inside can reach 60 °, and little its hard-over of front-wheel 1 corner of outside is 45 °, thereby can reach turning through minimum, and car does not fall safety and stability; As Fig. 6, shown in Figure 7: braking mechanism is by lock rope 10, troughing plate 11, U-shaped fork plate 12, rope sheave 14 and lock rope 15 are formed, lock rope 10 passes troughing plate 11 soldering tip on it and is fixed on the U-shaped fork plate 12, on the U-shaped fork plate 12 by the fixing rope sheave 14 and pin of little axle 13 with spring cotter, be wound with lock rope 15 on the rope sheave 14, its two ends lead to two left and right sides front-wheels 1 respectively, braking mechanism is pitched on 16 by the lamp that troughing plate 11 is fixed by bolts on the stem 8, the other end of lock rope 10 is fixed on the handlebar, and seal with dustproof with lid 20, the rope sheave 14 that adopts is equivalent to movable pulley, when with a lock rope on the right handlebar 10 pulling rope sheaves 14, on the rope sheave 14 around the two ends of lock rope 15 will transmit equal two front-wheels 1 of pulling force synchronous braking (braking method of trailing wheel 2 is identical with conventional approach).

Its advantage is: active force and thrust are all on the center of gravity of car body, so can not produce deflection torque, vehicle body Lack good stability, even the elderly is by bike also very safe when the ground cunning, and floor space is little, easily moves, Slim and graceful when riding, energy savings, electric power and manual dual-purpose namely still can briskly not advance when having electricity, use model Enclosing extensively is good walking-replacing tool.
