The utility model for the technical scheme that solves its technical matters and adopt is: a kind of novel flywheel locking gear, comprise motor wheel hub, flywheel body, the motor wheel hub of flywheel body inboard is provided with limiting and fixing device, limiting and fixing device is fixed on motor wheel hub, and flywheel body spline is connected in limiting and fixing device.
Further technical scheme of the present utility model is:
Limiting and fixing device is: anti-DNA releaxed circular DNA, locking ring set is located on the motor wheel hub flywheel end, anti-DNA releaxed circular DNA extends to form the facade flanging towards all sides of flywheel body one facade to its center, the facade flanging is provided with at least one tommy, the flywheel body is provided with the dowel hole that matches with tommy, tommy places dowel hole, like this flywheel body with regard to spline in anti-DNA releaxed circular DNA, be provided with at least one lock screw again, lock screw is rotated with and passes locking surrounding place side limit and press closer motor wheel hub, anti-like this DNA releaxed circular DNA just and the motor wheel hub stationkeeping, thereby the flywheel body just can not relatively rotate with motor wheel hub, and the flywheel body also just can not meet accident and motor wheel hub gets loose.
Limiting and fixing device is: anti-DNA releaxed circular DNA, locking ring set is located on the motor wheel hub flywheel end, anti-DNA releaxed circular DNA extends to form the facade flanging towards all sides of flywheel body one facade to its center, the facade flanging is provided with at least one tommy, the flywheel body is provided with the dowel hole that matches with tommy, tommy places dowel hole, like this flywheel body with regard to spline in anti-DNA releaxed circular DNA, an anti-DNA releaxed circular DNA facade of flywheel body dorsad extends to form facade button limit to its center, motor wheel hub is provided with the annular groove with facade button limit coupling, facade button limit is closely buckled in the annular groove, anti-like this DNA releaxed circular DNA just and the motor wheel hub stationkeeping, thereby the flywheel body just can not relatively rotate with motor wheel hub, and the flywheel body also just can not meet accident and motor wheel hub gets loose.Be closely buckled in the annular groove for the ease of facade button limit, form a slit on locking surrounding place side limit, gap opening is in motor wheel hub.
Anti-DNA releaxed circular DNA, locking ring set is located on the motor wheel hub flywheel end, anti-DNA releaxed circular DNA extends to form the facade flanging towards all sides of flywheel body one facade to its center, the facade flanging is provided with at least one tommy, the flywheel body is provided with the dowel hole that matches with tommy, tommy places dowel hole, like this flywheel body with regard to spline in anti-DNA releaxed circular DNA, establish breach on the motor wheel hub, locking surrounding place side limit is covered in breach, be pressed in the breach under all sides of part on the anti-DNA releaxed circular DNA, anti-like this DNA releaxed circular DNA just and the motor wheel hub stationkeeping, thereby the flywheel body just can not relatively rotate with motor wheel hub, and the flywheel body also just can not meet accident and motor wheel hub gets loose.
The beneficial effects of the utility model are: because the motor wheel hub of flywheel body inboard is provided with limiting and fixing device, limiting and fixing device is fixed on motor wheel hub, flywheel body spline is connected in limiting and fixing device, and the position is just fixing between motor wheel hub and flywheel body like this.After battery-driven car was ridden for a long time like this, flywheel can not get loose with motor wheel hub all the time.And the utility model is dismantled easily, and it is very convenient to change flywheel as need, so the utility model is simple and practical, safe and effective.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The STRUCTURE DECOMPOSITION scheme drawing of one of Fig. 1 the utility model embodiment;
Two STRUCTURE DECOMPOSITION scheme drawing of Fig. 2 the utility model embodiment;
Three STRUCTURE DECOMPOSITION scheme drawing of Fig. 3 the utility model embodiment.
The specific embodiment
A kind of novel flywheel locking gear comprises motor wheel hub 1, flywheel body 2, and the motor wheel hub of flywheel body inboard is provided with limiting and fixing device 3, and limiting and fixing device is fixed on motor wheel hub, and flywheel body spline is connected in limiting and fixing device.
Embodiment 1:
Limiting and fixing device is: anti-DNA releaxed circular DNA, locking ring set is located on the motor wheel hub flywheel end, anti-DNA releaxed circular DNA extends to form facade flanging 31 towards all sides of flywheel body one facade to its center, the facade flanging is provided with at least one tommy 32, the flywheel body is provided with the dowel hole 21 that matches with tommy, tommy places dowel hole, like this flywheel body with regard to spline in anti-DNA releaxed circular DNA, be provided with at least one lock screw 33 again, lock screw presses closer motor wheel hub after being rotated with and passing locking surrounding place side limit 34, anti-like this DNA releaxed circular DNA just and the motor wheel hub stationkeeping, thereby the flywheel body just can not relatively rotate with motor wheel hub, and the flywheel body also just can not meet accident and motor wheel hub gets loose.
Embodiment 2: limiting and fixing device is: anti-DNA releaxed circular DNA, locking ring set is located on the motor wheel hub flywheel end, anti-DNA releaxed circular DNA extends to form facade flanging 31 towards all sides of flywheel body one facade to its center, the facade flanging is provided with at least one tommy 32, the flywheel body is provided with the dowel hole 21 that matches with tommy, tommy places dowel hole, like this flywheel body with regard to spline in anti-DNA releaxed circular DNA, an anti-DNA releaxed circular DNA facade of flywheel body dorsad extends to form facade button limit 35 to its center, motor wheel hub is provided with the annular groove 11 with facade button limit coupling, facade button limit 35 is closely buckled in the annular groove 11, anti-like this DNA releaxed circular DNA just and the motor wheel hub stationkeeping, thereby the flywheel body just can not relatively rotate with motor wheel hub, and the flywheel body also just can not meet accident and motor wheel hub gets loose.Be closely buckled in the annular groove for the ease of facade button limit, form a slit 36 on locking surrounding place side limit, gap opening is in motor wheel hub.
Embodiment 3: anti-DNA releaxed circular DNA, locking ring set is located on the motor wheel hub flywheel end, anti-DNA releaxed circular DNA extends to form facade flanging 31 towards all sides of flywheel body one facade to its center, the facade flanging is provided with at least one tommy 32, the flywheel body is provided with the dowel hole 21 that matches with tommy, tommy places dowel hole, like this flywheel body with regard to spline in anti-DNA releaxed circular DNA, establish breach 12 on the motor wheel hub, locking surrounding place side limit 34 is covered in breach, be pressed on that (locking in this case surrounding place side limit 34 needs thin slightly in the breach part week on the anti-DNA releaxed circular DNA under the side, when dismantling as need, with screwdriver all sides are prized from breach again and get final product), anti-like this DNA releaxed circular DNA just and the motor wheel hub stationkeeping, thereby the flywheel body just can not relatively rotate with motor wheel hub, and the flywheel body also just can not meet accident and motor wheel hub gets loose.
The structure of present embodiment 1, embodiment 2, embodiment 3 makes flywheel be easy to dismounting in the time of need changing.
In this example, can set a position pin on the flywheel body, then: set a position pin-and-hole on the anti-DNA releaxed circular DNA facade flanging, same tommy places dowel hole, but the flywheel body just spline in fact need only a recessed male structure and can realize both splines in anti-DNA releaxed circular DNA.
