The function of the driving disk is used for outputting power output by the engine; the driven frame is used for outputting the power output by the driving disk; the elliptical wheel, the plane, the elastic pressing plate and the rollers have the functions that the driven frame is driven to rotate by utilizing the extrusion and the expansion of the two rollers; the touch plate and the guide chamfer have the functions that the guide chamfer is utilized to open the two rollers, so that the touch plate is arranged between the two rollers to drive the driven frame to rotate; the limiting round plate is used for limiting the roller and preventing the roller from being separated from the groove of the driving disc.

Further perfection, the surfaces of the two touch plates and the roller are provided with wear-resistant layers. The effect of wearing layer here improves the wearability of touch panel and running roller under high pressure environment, improves the life of touching version and running roller greatly, improves the life of clutch greatly.

Further perfection, the driving disc and the driven frame are both provided with poking blocks. The function of the poking block is that the poking block is used for installing the driving disc and for poking and moving the driven frame.

The utility model has the beneficial effects that: the utility model has ingenious and reasonable structural design, utilizes the driving disk to output the power output by the engine, utilizes the driven frame to output the power output by the driving disk, utilizes the elliptical wheel, the plane, the elastic pressure plate and the roller wheel to be extruded and stretched by the two roller wheels so as to drive the driven frame to rotate, utilizes the touch plate and the guide chamfer to prop the two roller wheels by the guide chamfer so as to install the touch plate between the two roller wheels and further drive the driven frame to rotate, utilizes the limit circular plate to limit the roller wheels so as to avoid the roller wheels from falling out of the groove of the driving disk, has ingenious and reasonable structural design, avoids the situation that the roller wheels are easy to slip or be burnt out by friction and overheating like a traditional friction clutch by utilizing the clamping force of the roller wheels, so that the output shaft has strong power and stable output power, and can bidirectionally drive the driven frame to rotate, the friction clutch is not available in the traditional friction clutch and is worth popularizing and applying.

Description of reference numerals: the device comprises a driving disc 1, an elliptical wheel 1-1, a plane 1-1a, an elastic pressing plate 1-2, a roller 1-3, a driven frame 2, a frame body 2-1, a touch plate 2-2, a guide chamfer 2-2a, a wear-resistant layer 3, a poking block 4 and a limiting circular plate 5.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the equipment or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

With reference to the accompanying drawings: the novel bidirectional driving clutch comprises a driving disc 1, wherein a driven frame 2 is arranged on the side part of the driving disc 1; an elliptical wheel 1-1 is fixed in the driving disc 1, the left side and the right side of the elliptical wheel 1-1 are respectively provided with a plane 1-1a, an elastic pressure plate 1-2 is fixed on each plane 1-1a, and a roller 1-3 is arranged between each elastic pressure plate 1-2 and the outer contour of the elliptical wheel 1-1; the driven frame 2 comprises a frame body 2-1, touch plates 2-2 are fixed at the upper end and the lower end of the frame body 2-1, and guide chamfers 2-2a are arranged on two sides of the head end of each touch plate 2-2; a limiting circular plate 5 for preventing the rollers 1-3 from falling out of the groove of the driving disc 1 is fixed at the driving disc 1.
