Abstract

The utility model discloses a two-wheeled vehicle rotated by clamping wheels. A pair of driving discs (1) clamped on the edge of a wheel rim is arranged, a central shaft of each driving disc is connected with a power driving device, a circle of rolling bodies are arranged on the edge of each driving disc, and each driving disc is in contact with the wheel rim through a pressing device and the rolling bodies. The two-wheeled vehicle transfers the power to the wheel rim of the vehicle through the driving discs; and the wheel rim, which has a longer force arm relative to the rotating center, can generate larger torque even under the same force and overcome the defect that the traditional two-wheeled vehicle transfers the torque through the center of the rotating shaft.

Description

The card wheel rotates two-wheel car

Technical field

The utility model relates generally to a kind of vehicle that advances by wheel, and particularly a kind of manpower drives or motor-driven power-actuated two-wheel car.

Technical background

The vehicle that advances by vehicle, particularly a kind of two-wheel car that no matter uses which kind of power, as bicycle, motor bike etc., the required power of drive wheel all is to connect transmission of power with sprocket chain device, general direct with transmission of power to the drive wheel center shaft with sprocket wheel on, because the radius of sprocket wheel is very little, so the arm of force that produces is also little, same power is also very little to the moment of torsion that drive wheel produced, add this type of drive complex structure, driving efficiency is low, is out of order easily, and the structure of therefore improving driving device is necessary.

The utility model content

The purpose of this utility model is to provide a kind of shortcoming that can overcome known technology, and the card wheel that can significantly improve driving efficiency rotates two-wheel car.

For achieving the above object, scheme of the present utility model is: a pair of driving disk that is stuck in the wheel rim edge is set, and the center shaft of driving disk links to each other with power drive, and the edge of driving disk is provided with a circle rolling body, described driving disk utilizes rolling body to contact with wheel rim by pinch device.

Utilize said apparatus, transmission of power is given the wheel rim of vehicle by driving disk, because wheel rim has the long arm of force with respect to center of turn, even so power of identical size, also can produce bigger moment of torsion, overcome the shortcoming of traditional two-wheel car, thereby realized the purpose of this utility model by wheel shaft center transfer torque.

Below in conjunction with diagram and embodiment scheme is described in more detail.

The specific embodiment

Comprise as shown in Figure 1 and be provided with driving disk 1, driving disk has center of gyration 2, the rotational power of driving disk has multiple, comprise manpower, combustion engine powered or electrical motor, preceding two kinds of power can transmit with transmission device, as adopt electrical motor, driving disk 1 can be directly installed on the axle head of electrical motor, and the edge of driving disk is equipped with a circle rolling body 3, and each rolling body has the center of gyration of oneself, be pressed on the wheel rim 4 by rolling body, when driving disk 1 drives rotation by power, rotate with frictional transmission driven wheel circle 4 by rolling body, make driving disk press to wheel rim by tightening device.

Described driving disk 1 is a dish, and the edge of dish has the hole 5 that a circle holds single rolling body 3, also has the hole 6 that a circle holds the stretching device bolt, and the center of driving disk has the hole 7 that transmission shaft is installed.

Single rolling body 3 is a fusiform gyro-rotor, as shown in Figure 3, two ends respectively have the minor axis 8 of a square-section, above-mentioned rolling body is packed in as shown in Figure 5 the structure, minor axis 8 is cooperated with square hole on the axle sleeve 9, the hole 11 of being opened on the outer circumference surface of axle sleeve 9 and the dovetail form bearing seat 10 cooperates, described dovetail form bearing seat 10 is separately positioned on the two ends of single rolling body 5, opening the location benchmark for dovetail form bearing seat 10 is installed at driving disk 1 accordingly and be one looks from card and to be pit, the shape of pit conforms to dovetail form bearing seat 10, the two ends of each single rolling body 5 respectively are with an above-mentioned dovetail form bearing seat 10, the small end of dovetail form bearing seat 10 has screw, after in the positioning pit on the rolling body 5 that bearing seat 10 is installed is packed driving disk into, with bolt 12 fixed axis bearings 10, the mounting means of design rolling body 5 is convenient to Assembly ﹠Disassembly on the card like this, and bolt 12 is in the outside of driving disk usually, does not disturb cooperating between rolling body and the wheel rim.

Fig. 6 is the pinch device of driving disk, comprises one group of bolt 13 that run through two dishes, and the screw 6 that bolt is opened from the driving disk 1 in advance penetrates, cover upper spring 14 backs screw with nut on the screw rod, rely on spring that driving disk is pressed to wheel rim,, can change the effect that driving disk drives wheel rim by regulating tensioning spring.

Fig. 7 is the type of drive when propulsion source is combustion engine, and driving device comprises one group of gear transmission, and Fig. 7 is a gear transmission mode, by one group of gear 15 transmission of power of combustion engine 16 is given in the rotating shaft of

driving disk

1, and 17 are combustion engine suspension axis hole.

Adopt the card wheel of the utility model scheme to rotate two-wheel car, acting point is acted on the wheel rim of two-wheel car, to the power that provides equally, can increase the moment of torsion of several times, therefore can reduce the structure and the power of propulsion source, and transmission performance is stable, and the transmission failure frequency reduces, thereby design is rational.
