detailed description

The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

As shown in Figures 1 to 8, a portable electric vehicle with clutchable wheels includes a vehicle frame 1, a front wheel 11 and a rear wheel. The rear wheel includes a left half wheel and a right half wheel, and a left half wheel and a right half wheel. The half-wheels are all represented by a label 2, the left half-wheel and the right half-wheel slide axially on two sliding shafts 3 respectively, a clutch device is arranged in the middle of the two sliding shafts, and a rotating arm 4 is fixed on the outer end of each sliding shaft to rotate The front end of the arm is hinged with the frame 1, and the clutch device combines the rotating arm to drive the angle change between the two sliding shafts to realize inclination (inward splayed) or outward inclination (outward splayed), and finally make the left half The wheel and the right half wheel are automatically separated or closed. When inclining, as shown in Figure 7, the left half wheel and the right half wheel generate a sliding speed to both sides, thereby automatically separating the left half wheel and the right half wheel, and the whole vehicle Switch to the three-wheel state, when the camber, as shown in Figure 8, the left half-wheel and the right half-wheel produce a partial speed that slides toward the center, and the left half-wheel and the right half-wheel are combined into one rear wheel, so that the three-wheel The state is re-switched to the two-wheel state. Using this structure, the driver can switch between the three-wheel and two-wheel states according to the actual driving environment. In busy urban areas, it can switch to the three-wheel state to increase the stability at low speeds. When smooth, switch to the two-wheel state to reduce resistance and further increase driving speed.

The clutch device includes two vertical chute 51, the chute is connected with a U-shaped shift fork 52, the two ends of the U-shaped shift fork slide in the chute respectively, when the U-shaped shift fork rotates at the center, two The two chutes are separated and closed, see Figure 5 and Figure 6 for details. In Figure 5, the U-shaped shift fork is placed horizontally, and the positions of the two chutes are separated to the maximum position by the U-shaped shift fork. In Figure 6, the U-shaped shift fork Rotate at a certain angle, the U-shaped fork moves the two chutes to the middle, and the distance between the two chutes is reduced to the minimum, so that the two chutes are closed, the outer wall of the chute is fixed to the inner end of the sliding shaft, and the chute is separated. When closing, drive the sliding shaft to separate and close; in addition, for the convenience of the driver, the U-shaped shift fork is connected with a movable joint 53, a pedal 54 is connected above the movable joint, and two connecting rods are connected between the movable joint and the pedal. , when the pedal is stepped left and right, the drive connecting rod is transmitted to the movable joint, and finally the U-shaped shift fork is driven to rotate clockwise or counterclockwise. In addition, the two ends of the U-shaped shift fork are provided with pulleys 55, and the pulleys can also be replaced by bearings. Or the bearing can reduce the coefficient of friction between the U-shaped shift fork and the chute to increase the service life.

The front wheels are arranged in front of the vehicle frame, and the front wheels are connected with a motor and a storage battery. Above the vehicle frame is a platform plate 7, and a shock absorber 71 and a shock absorber spring are arranged between the platform plate, the vehicle frame, and the rotating arm. 72. Increase the shock absorption effect of the electric vehicle.

Preferably, the sliding shaft is a splined sliding shaft, splined bearings 32 are arranged between the left half wheel, the right half wheel and the sliding shaft, the splined sliding shaft ensures smooth axial sliding, and the splined sliding shaft is wiped Lubricating oil; the outside of the left half wheel and the right half wheel is provided with a brake disc 21, and the outer side of the brake disc is provided with a dust cover 22, which can prevent dust and prevent dust from entering the splined sliding shaft to avoid splines. Seizure occurs when the key bearing slides on the splined slide shaft.

In addition, in this solution, the speed limiting function of the three-wheel state is additionally added. The front end of the chute is fixed with a metal L-shaped bracket 6 bent outward, and the inner side of the rotating arm is provided with a suction ring that is attracted to the outer end of the L-shaped bracket. Magnet 41, L-shaped bracket outer end is provided with push-type switch 61, when left half-wheel and right half-wheel move to both sides when approaching the maximum edge, the outer end of L-shaped bracket bent outward just fits with the inner side of rotating arm, because When the rotating arm rotates, there will be a certain inclination angle on the inner side, and the actual design of the outer end of the L-shaped bracket should also have a certain slope to increase the degree of fit when the two are in contact. The magnet on the inner wall of the rotating arm is attracted to the L-shaped bracket. Press the push switch 61, and the speed limit switch is activated, which can make the vehicle at a slower speed and improve stability; in addition, the inner side wall of one of the two L-shaped brackets is also provided with a magnet 41 and a push switch 61 , when the left half-wheel and the right half-wheel moved to the middle, two L-shaped support inner walls fit and pressed the push-type switch 61, and now the speed limit switch was removed, returned to normal speed, and increased the speed of two-wheel travel. The inside of the L-shaped bracket is provided with a wire groove for the wire to pass through. The wire is connected to the push switch. The wire is built into the wire groove to prevent aging, and can also avoid some hard objects on the road to improve safety.

The above is only an illustration of the preferred examples of the present invention, but should not be construed as a limitation on the claims. The present invention is not only limited to the above examples, its specific structure allows changes, and those skilled in the art can make various changes and deformations according to the present invention, as long as they do not depart from the spirit of the present invention, all should belong to the definition of the appended claims of the present invention scope.
