Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figures 1 to 8, a kind of wheel isolating construction based on U-shaped shift fork, comprise trailing wheel, described trailing wheel comprises about two half wheels 2, arrangement of clutch is provided with in the middle of about two half wheels, described arrangement of clutch comprises two chutes 51 vertically established, chute is connected with U-shaped shift fork 52, slide respectively in chute in U-shaped shift fork two ends, U-shaped shift fork drives two chute parallel motions to realize being separated with U-shaped shift fork two ends during center rotating, close up, thus drive left and right half wheel be separated or close up, realize two to take turns, the switching of three-wheel state, arrangement of clutch is specifically see Fig. 5 and Fig. 6, in Fig. 5, U-shaped shift fork horizontal positioned, the position of two chutes is separated to maximum position by U-shaped shift fork, in Fig. 6, U-shaped shift fork rotates to an angle, U-shaped shift fork stirs two chutes toward middle mobile, the distance of two chutes is narrowed down to minimum, realize two chutes to close up, chute outer wall and slide shaft medial extremity are fixed, chute is separated, slide shaft is driven to be separated when closing up, close up, in addition, in order to driver's handled easily, described U-shaped shift fork is connected with active section 53, one piece of pedal 54 is connected above active section, two connecting rods are connected with between active section and pedal, when stepping on about pedal, drive link is transferred to active section, final driving U-shaped shift fork cw or rotate counterclockwise, U-shaped shift fork two ends are provided with pulley 55 in addition, and pulley also can replace with bearing, and pulley or bearing can reduce the friction coefficient between U-shaped shift fork and chute, increase service life.After adopting the technical program, arrangement of clutch is rotated by U-shaped shift fork and realizes left and right clutch, very laborsaving, when about two half wheels are merged into a trailing wheel, resistance is less, running velocity is fast, when about two half wheels separate, resistance strengthens, speed is relatively slow, and three-wheel take turns traveling than two more stable, utilize this structure driver can switch three-wheel voluntarily according to actual driving environment, two take turns state, three-wheel state can be switched in busy urban district, increase stability during low speed, when road conditions are comparatively smooth and easy, be switched to two and take turns state, reduce resistance, drive speed can be promoted further.
The distance be separated due to left and right half wheel in said structure all relies on the two ends distance of U-shaped shift fork to determine, when U-shaped shift fork two ends distance is larger, two wheels are separated distant, otherwise then segregation ratio is shorter, when wheel is separated far away, U-shaped shift fork is because certain load of bearing, be very easy to bending when the situation lower stress of longer dimension, so very high concerning requiring U-shaped shift fork itself, in order to solve this problem, improve in this programme, about two half wheels slide axially respectively on two slide shafts 3, arrangement of clutch is provided with in the middle of two slide shafts, every root slide shaft external side end is fixed with swivel arm 4, swivel arm front end and vehicle frame 1 hinged, like this, when arrangement of clutch in the middle of slide shaft carries out left and right separation, swivel arm front end is driven to rotate, thus make variable angle between two slide shafts, two slide shafts are finally made to present introversion (interior Eight characters shape) or flare (outer Eight characters shape), the angle between about two half wheels can be made like this to change, when introversion, as shown in Figure 7, about two half wheels produce the component velocity of sliding to both sides, thus automatically partly take turns separation by about two, car load is switched to three-wheel state, when flare, as shown in Figure 8, about two half wheels produce the component velocity of past central slide, about two half wheels are merged into a trailing wheel, thus three-wheel state is switched to two again takes turns state, such structure achieves left and right half wheel after arrangement of clutch regulates, automatic sliding one segment distance can also be continued, what arrangement of clutch then played is the function regulating angle, the distance of the separation of about two half wheels is not at the dimensional restriction by U-shaped shift fork, length between the two ends of U-shaped shift fork can be relatively shorter, larger load can be born do not bend.
Described front-wheel is located at vehicle frame front, and front-wheel is connected with motor and storage battery, is platform slab 7 above described vehicle frame, is provided with bumper 71 and damping spring 72 between platform slab and vehicle frame, swivel arm, increases the car load shock-proof effect of battery-driven car.
Preferably, described slide shaft is spline slide axle, spline bearing 32 is provided with between left and right half wheel and slide shaft, the guarantee of spline slide axle slides axially smooth and easy, spline slide axle adds and smears lubricating oil, and wheel outside, described left and right half is provided with brake disc 21, dust protecting cap 22 is provided with outside brake disc, dust protecting cap can be dust-proof, prevents micronic dust from entering on spline slide axle, when sliding on spline slide axle to avoid spline bearing, stuck phenomenon occurs.
In addition, the extra speed limiting function increasing three-wheel state in this programme, described chute front end is fixed with the metal L bracket 6 of lateral bend outward, the magnet 41 attracting with L bracket external side end is provided with inside described swivel arm, L bracket external side end is provided with push switch 61, when left and right half wheel moves near maximal margin place toward both sides, the external side end of L bracket lateral bend outward just with inside swivel arm is fitted, because have certain angle of inclination inside when swivel arm rotates, laminating degree when constant slope also should be had during L bracket external side end actual design to contact with both increases, by the magnet of swivel arm madial wall and L bracket is attracting presses push switch 61, speed limiting switch starts, car load can be allowed to be in comparatively jogging speed, improve stability, in addition, the described two L brackets wherein madial wall of are also provided with magnet 41 and push switch 61, when left and right half wheel is toward middle movement, push switch 61 is pressed in two L bracket madial wall laminatings, now speed limiting switch is removed, return to normal speed to travel, increase the speed that two take turns traveling.Described L bracket inside is provided with the wire casing passed for wire, the push switch described in wire connects, and wire is built in wire casing and prevents aging, some road surface hard object also can be avoided to clash into, improve safety.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
