Abstract
The utility model relates to a turning prevention device of an electric bicycle wheel hub. A unique turning prevention profile nut which can be conveniently arranged on a rear shaft of the electric bicycle reinforces tightening torque, effectively prevents the rear shaft of the electric bicycle from sliding, and prevents the wheel hub of the electric bicycle from rotating in load weighting. The utility model has the advantages of simple and easy operation, easy installation and good turning prevention effect.
Description
The utility model relates to the manufacturing field of Electrical Bicycle.
The structure of Electrical Bicycle all is that electrical motor is contained in the wheel hub at present, driving flywheel when electrical motor rotates rotates, wheel hub and flywheel all are fixed on the rear axle of Electrical Bicycle, and rear axle is fastening by vehicle frame chain stay and nut, wheel hub and rear axle any rotation that all do not have when the motor drives flywheel rotates.Yet vehicle frame chain stay frame is on rear axle, shaft diameter is limited behind the general Electrical Bicycle, only there is the twice nick to rise as high as the banks above, the constant moment of vehicle frame chain stay and nut also has certain limit like this, when Electrical Bicycle starting and climbing need bigger twist moment, causes the fixedly shakiness of rear axle sometimes, produce stripped thread, and once stripped thread is arranged, then can cause wheel hub and rear axle to slide very soon or rotate, cause the damage of Electrical Bicycle.
The purpose of this utility model is exactly the wheel hub anti-rotation device of a kind of Electrical Bicycle of design, is installed on the rear axle, can strengthen Tightening moment greatly, prevents that effectively Electrical Bicycle produces rear axle stripped thread and wheel hub rotation when load increases the weight of.
The purpose of this utility model is to realize like this, specially design a spline abnormity nut, this nut one end is the plane, the other end has two protruding reinforcing ribs, each reinforced rib width is consistent with shaft diameter behind the battery-driven car, and highly being about 1/3 of spline abnormity nut height, two protruding reinforcing ribs are just in time lived by vehicle frame chain stay mounting board when being contained on the Electrical Bicycle rear axle, screw with plain nut again.Leave the lock screw hole in spline abnormity nut both sides in addition, can be fixed on the rear axle with lock screw, design has increased the fastening force between each parts greatly like this, and actv. has prevented the unnecessary rotation of wheel hub.
Below in conjunction with accompanying drawing its concrete structure and installation position are described.
Fig. 1 is the scheme drawing of this spline abnormity nut, wherein 1 is protruding reinforcing rib, each reinforced rib width is consistent with shaft diameter behind the battery-driven car, and highly is about 1/3 of spline abnormity nut height, and its upper end and two sides all are the plane, the 2nd, set screw hole, two sides respectively have one, penetrate into centre hole in this nut, and two holding screw hole site lines are just in time vertical with two protruding reinforcing rib position lines, the 3rd, negative thread just in time meshes with the Electrical Bicycle rear axle.
Fig. 2 is the front view after the wheel hub anti-rotation device of this Electrical Bicycle is installed.Wherein 4 is wheel hubs, the 5th, and flywheel, the 6th, vehicle frame chain stay, the 7th, spline abnormity nut, the 8th, plain nut, the 9th, spring washer, the 10th, flat gasket, the 11st, Electrical Bicycle support, the 12nd, rear axle.The spline abnormity nut screws on the Electrical Bicycle rear axle, with the end on plane to flywheel, it is parallel with the vehicle frame chain stay that the other end is torqued-up to the position that makes two protruding reinforcing ribs, make the vehicle frame chain stay just in time clamp this two protruding blocks reinforced rib, again the Electrical Bicycle support is loaded onto, fastening good with flat gasket, spring washer and plain nut, the holding screw of spline abnormity nut both sides is tightened on the rear axle, then install.
Design and the wheel hub anti-rotation device of this Electrical Bicycle is installed after, strengthened the anti-rotation ability of wheel hub and rear axle greatly, the phenomenon that wheel hub and rear axle can slide or rotate when occurring load never again and increasing the weight of.
Claims (2)
1. wheel hub anti-rotation device that is used for Electrical Bicycle, it is characterized in that on the Electrical Bicycle rear axle, installing additional the spline abnormity nut, this helical one end is the plane, the other end has two protruding reinforcing ribs, the width of each reinforced rib is consistent with shaft diameter behind the Electrical Bicycle, and highly is about 1/3 of spline abnormity nut height.
2. by the wheel hub anti-rotation device of the described Electrical Bicycle of claim 1, it is characterized in that there is the lock screw hole spline abnormity nut two sides.
