Description
Technical field
The utility model relates to electric bicycle technical field, more particularly, relates to a kind of cassette motor and a kind of electric bicycle.
Background technology
Along with socioeconomic fast development, energy shortage problem is increasingly serious, has accelerated the research steps of people to the new forms of energy vehicles, and thus, energy-conserving and environment-protective, economy and durability, electric bicycle time saving and energy saving and light and fast arise at the historic moment.
For preventing that electric bicycle from cannot continue to travel in the time losing supply of electric power, existing electric bicycle has all retained moveable endless, but in the time running into the operating mode of upward slope or Uneven road, pedal travels and requires great effort very much, therefore on the rear-mounted motor of most of electric bicycle, cassette multistage flying wheel is often installed, to realize the foot pedal speed changing function of electric bicycle.
Widely used rear-mounted motor (also claiming cassette motor) mainly contains two kinds in the market.For a kind of cassette motor wherein, though the cassette overcoat of cassette body is quick detachable, the bearing of motor end cap can not be taken into account the supporting of cassette body, and therefore cassette body still needs built-in two bearings, thereby has increased the axial installation dimension of cassette motor.Although and another cassette motor can not increase the axial installation dimension of cassette motor, it is to adopt to be threaded with motor end cap that the card of cassette body flies fuse, can ride tighter and tighter in the process of riding, and is difficult to dismounting in the time that cassette body damages.
Thus, need the Novel clamped motor of developing a kind of cassette body convenient disassembly and can not increasing axial installation dimension badly.
Utility model content
In view of this, the utility model provides a kind of cassette motor and a kind of electric bicycle, to realize in the case of the axial installation dimension that does not increase cassette motor, reaches the easily object of dismounting cassette body.
A kind of cassette motor, comprises motor body and cassette body, wherein:
Described motor body comprises the motor end cap of outputting power;
Described cassette body comprises: the card of fast demountable on described motor end cap flies fuse; Rotatingly be arranged on described card and fly the cassette overcoat on fuse; Be installed on described card and fly on fuse, ensure that the relatively described card of described cassette overcoat flies the very heavy of fuse one-directional rotation and spring silk; And be arranged at motor shaft and described card flies the bearing between fuse;
Described bearing comprises the clutch shaft bearing shared with described motor end cap.
Alternatively, described cassette body also comprises that being fixed on described card flies the breach silk shelves on fuse, and described bearing also comprises the second bearing being installed between described breach silk shelves inwall and described motor shaft.
Wherein, the end that described card flies fuse is designed with ring flange, and described ring flange is fixed on the installation locating shoulder of described motor end cap by screw.
Wherein, described clutch shaft bearing is installed between described ring flange inwall and described motor shaft.
A kind of electric bicycle, comprises above-mentioned any cassette motor.
Can find out from above-mentioned technical scheme, the utility model improves by the syndeton that card is flown between body and motor end cap, make described card fly body fast demountable on described motor end cap, therefore when described card fly body damage time get final product easy removal, reduced cassette motor maintenance cost, saved maintenance time; Meanwhile, share a bearing because motor end cap and described card fly fuse, therefore also just can not increase the axial installation dimension of cassette motor.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the disclosed a kind of cassette motor configuration schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment discloses a kind of cassette motor, to realize under the prerequisite of axial installation dimension that does not increase cassette motor, reaches the object of light dismounting cassette body, and this cassette motor comprises motor body and cassette body, wherein:
Described motor body comprises the motor end cap 1 of outputting power;
Described cassette body comprises: the card of fast demountable on motor end cap 1 flies fuse 2; The rotating card that is arranged on flies the cassette overcoat 3 on fuse 2; Be installed on card and fly on fuse 2, ensure that cassette overcoat 3 blocks very heavy 4 and the spring silk 5 that fly fuse 2 one-directional rotation relatively; And be arranged at motor shaft 7 and block the bearing flying between fuse 2;
Described bearing comprises the clutch shaft bearing 6 shared with motor end cap 1.
Wherein, the end that card flies fuse 2 is designed with ring flange, and described ring flange is fixed on by screw on the installation locating shoulder of motor end cap 1; In addition, described cassette body also comprises that being fixed on card flies the breach silk shelves 8 on fuse 2, and described bearing also comprises the second bearing 9 being installed between breach silk shelves 8 inwalls and motor shaft 7.Clutch shaft bearing 6 and the second bearing 9 have supported described cassette body jointly, and this structure has realized rapid-assembling and the dismounting of described cassette body.
Wherein, clutch shaft bearing 6 is installed between the ring flange inwall and motor shaft 7 that card flies fuse 2, because clutch shaft bearing 6 is the bearing of motor end cap 1 simultaneously,, motor end cap 1 flies fuse 2 with card and shares a bearing, therefore this structure can avoid increasing the axial installation dimension of cassette motor, makes it be applicable to the standard of vehicle frame after electric bicycle and opens gear.
General cassette multistage flying wheel can be installed in the market on described cassette body, and cassette overcoat 3 can be set with the cassette multistage flying wheel with 5 grades, 6 grades, 7 grades, 8 grades, 9 grades or 10 grades film flyings; Due to the easy dismounting of film flying of described cassette multistage flying wheel, therefore can realize the monolithic of cassette multistage flying wheel and exchange, the maintenance cost of saving described cassette multistage flying wheel.
