Description

Side-mounted power driver

The utility model relates to a kind of transmission device with electrically driven vehicle.

At present, electric bicycle, the power driver that motor vehicle such as Moped Scooter and battery-operated motor cycle is commonly used all be hub-type or middle, I also have close place at rim type power driver and this class power driver of invention, they all are that permanent magnet direct current motor and variable speed drive are installed in the wheel hub, wheel hub is bearing on the dead axle, adopt planetary reducer as variable speed drive, the employing freewheel clutch that the clutch mode has, the employing single roll bearing that has, adopt the freewheel clutch person also the roller pressing plate need be arranged, and be mostly color with braiding width of cloth bar as being connected between wheel hub and the tyre rim.Because it adopts planetary gear speed-reduction, thereby its structure is still complicated.Noise is still bigger, and life-span and mechanical efficiency are still not high enough, and power driver itself is difficult for being provided with brake apparatus, nor is convenient to Fast Installation.

Task of the present utility model is the shortcoming that will overcome above-mentioned power driver, provides a kind of structure simpler, and noise is littler, the side-mounted power driver that useful life and mechanism efficiency are all higher.

Task of the present utility model is finished like this: permanent magnet direct current motor and mechanical reduction gear are not to be contained in the wheel hub, but are contained in the special actuator housing; This actuator housing is made up of an open-ended cavity that has a biasing flange base plate and a flange shrouding disc and a chamber lid, makes two cavity shells of a biasing control tower shape of housing formation; Flange shrouding disc and base plate synthesize flat big chamber, permanent magnet direct current motor wherein is installed, chamber lid and the synthetic long loculus of open-ended cavity, the motor shaft in the big chamber stretches in the loculus, the pinion of axle head and the gear wheel on the output shaft in the loculus directly or indirectly mesh, and constitute the roller gear deceleration device.

The roller gear deceleration device can be directly to mesh the primary cylinder gear speed reduction gearing that constitutes by pinion on the motor reel and the gear wheel on the output shaft, also can be the secondary roller gear speed reduction gearing that is made of pinion on the pinion on the motor reel and engagement of the gear wheel on the jack shaft and the jack shaft and the engagement of the gear wheel on the output shaft.

Cover also in the chamber of actuator housing brake shoe bolster and camshaft can outwards be set, supporting on bolster and the camshaft has a pair of brake shoe with the extension spring tension, stretch out outside the lid of chamber the outer end of output shaft, is shaped on spline on it, and the spline axle journal of output shaft is fixed with brake rim.Also can directly burn-on on the brake rim or the steel ring of tire is installed with bolted.

Because the utility model is that permanent magnet direct current motor and mechanical reduction gear are contained in the special actuator housing, and mechanical reduction gear is the one-level or the secondary column gear transmission of external toothing, thereby compare with original hub-type or rim type power driver, gear or gear shaft reduce 40%-60%, noise reduces about 6 decibels, mechanical efficiency improves about 2-3%, also increase useful life, and driver itself can directly be installed brake apparatus, adaptability is strengthened, its installation on the vehicle is also easy especially.

Be elaborated below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the schematic appearance that the utility model has brake apparatus.Fig. 2 is the structural representation of the A-A section among Fig. 1.

With reference to accompanying drawing, actuator housing is made up of the open-ended cavity 2 of the flange base plate 1 that has biasing and peviform shrouding disc 3 and chamber lid 4.Shrouding disc 3 is fastening with base plate 1 usefulness screw, synthetic flat big chamber 5, and chamber lid 4 is fastening with cavity 2 usefulness screws, synthetic long loculus 6.Big chamber is parallel with the center line of loculus and be offset certain distance, thereby makes whole housing form control tower shape two cavity shells of a biasing.The permanent magnet direct current motor that is made of motor shaft 7, rotating disk 8, printing winding armature 9, yoke plate 10, magnet steel 11, carbon brush 12 and lead 13 is housed in the big chamber 5.Motor shaft 7 is gear shafts, and it is bearing on the two bearings 14 of base plate 1.Its end that stretches in the big chamber 5 is fixed with rotating disk 8, and an end that stretches in the loculus 6 has pinion 15.The central lines in the center line of motor shaft 7 and big chamber 5.In the loculus 6, bearing 16 and 17 is supporting output shaft (being driving shaft) 18, the central lines of this center line and loculus.The single roll bearing 19 of freewheel clutch effect has been housed on this interior end-journal, be fixed with the gear wheel 20 that constitutes the primary cylinder gear deceleration transmission with pinion 15 engagements of motor shaft end on the bearing, stretch out outside the chamber lid 4 outer end of axle, and spline 21 is arranged on it.The both sides of output shaft also is equipped with brake shoe bolster 22 and camshaft 23 respectively on the lid 4 of chamber, and a pair of brake shoe 24 usefulness two extension springs 25 tensions are supported on bolster and the camshaft.The brake rim 26 with nut 25 lockings also is equipped with at the spline 21 axle journal places of output shaft, is welded with the steel ring 27 that can adorn rubber tyre on the brake rim.Can see that by Fig. 2 cavity 2 has a recess 28 at the position of camshaft 23, be used on camshaft, the rocking arm 30 that has pull bar 29 being installed.Also can see simultaneously, also can utilize remaining space that a jack shaft (not drawing among the figure) parallel with motor shaft 7 and output shaft 18 and triangularity is arranged is set in the loculus 6, allow gear wheel engagement on pinion 15 and the jack shaft on the motor shaft, allow pinion and 20 engagements of the gear wheel on the output shaft on the jack shaft, thereby form secondary roller gear deceleration device.In addition, the outside of flange base plate 1 also has installation base 31 and the screw hole 32 of whole power driver being installed, also can be play the reinforcement effect on the vehicle, the hangers 33 that is connected with the vibration absorber of vehicle in addition.

The utility model can directly weld or be connected the left side or the right side of wheel rim with screw, forms side-mounted power driver, directly drives the wheel rim rotation.It can form electric bicycle, battery-operated motor cycle or electric automobile with the vehicle frame of bicycle, motorcycle or car.This motor vehicle is simple in structure, cost is low, non-exhaust emission, can not cause environmental pollution, and noise is little, can carry out infinitely variable speeds, handle easily, and be a kind of comparatively ideal environmental-protecting type electric car.
