Abstract
The utility model discloses a driving device for electric vehicles, which comprises a DC motor and a gear reducer. The utility model is characterized in that the DC motor is connected and integrated with the gear reducer by a base seat (15) and a bolt (14); a clutch with a double-way engaging and disengaging function is composed of the central shaft (30) of the gear reducer and an output shaft sleeve (36) through a coupler (31, 33) with two clutches (28, 34). The utility model has the advantages of compact and reasonable structure, reliable performance, convenient installation, easy maintenance, beautiful appearance and strong practicability. The utility model is an ideal upgrading and improved product for bicycles.
Description
The utility model relates to Electrical Bicycle technical field, specifically electric motor car driver.
Mostly existing light-weight electric motor vehicle drive system is motor and reductor are separated design and installation, with regard to making that volume subject matter excessive, that in use occur is can not make things convenient for, be installed in deftly on bicycle and the battery-operated motor cycle, influenced motor driver promoting the use of on light-duty vehicle like this.
The purpose of this utility model provide a kind of simple in structure, compact, be convenient to install, for ease of maintenaince, economical and practical electric motor car driver.
Utility model is achieved in that and comprises DC machine and gear reduction unit, it is characterized in that DC machine and gear reducer are one by support and bolted connection, axis and output sleeve are combined into a power-transfer clutch with two-way clutch function by the coupler that has two power-transfer clutchs on the gear reduction unit.The ingenious combination of two overriding clutchs organically combines motor-driven the driving with strength of one's legs.
The utility model is described in further detail below in conjunction with accompanying drawing, but be not limited to shown in the accompanying drawing.
Fig. 1 looks complete section figure for the utility model master
Fig. 2 is the utility model left view
Fig. 3 is a utilization example one of the present utility model
Fig. 4 is a utilization example two of the present utility model
Among the figure, 1-push bolt, 2-bearing, 3-axle sleeve, the 4-key, 5-motor cover, 6-motor gear axle, 7-key, 8-armature plate pallet, 9-brush holder, 10-carbon brush, 11-magnet steel, the 12-armature plate, 13-yoke, 14-bolt, 15-support, the 16-bolt, 17-bearing, 18-back-up ring, 19-bearing, 20-first order big gear wheel, 21-bearing, 22-key, 23-first order pinion shaft, 24-second stage big gear wheel, 25-sprocket wheel, 26-cover, 27-bolt, 28-power-transfer clutch (bicycle flies for a short time), 29-key, 30-axis, 31-coupler, the 32-plain bearing, 33-coupler, 34-power-transfer clutch (bicycle flies for a short time), 35-bearing, the 36-output sleeve, 37-key, 38-cover, 39-stretcher.
As shown in Figure 1, 2, the utility model partly is made up of motor and reductor two.
1, motor.Motor cover 5 is fixed on the support 15 by bolt 14.With Bolt Connection yoke 13, the two has constituted motor supporting member partly on the support right flank.Motor gear axle 6 is fixed in the input through hole of support 15 by bearing 17 and 19, back-up ring 18, can rotate.Armature plate 12 is adhesively fixed on the armature plate pallet 8, and armature plate pallet 8 is fixed in the left end of motor gear axle 6 by key 7 and back-up ring 18.Magnet steel 11 evenly is bonded on the motor cover 5, with the yoke 13 formation motor flux paths on the right side on the support 15.Brush holder 9 is fixed on the motor cover 5, and wherein the both positive and negative polarity lead can be with current delivery to armature plate 12 by carbon brush 10.
2, reductor.Support 15 is one with cover 38 by bolted connection, is the supporting part of reducer gear transmission.First order pinion shaft 23 combines as a whole by key 22 with first order big gear wheel 20, is supported on respectively on support 15 and the cover 38 by bearing 21 again, can be around rotational.Second stage big gear wheel 24 combines as a whole by key 4 and axle sleeve 36, can drive output sleeve 36 around rotational; And by key 37 power is passed on the power-transfer clutch 34, again by being connected sprocket wheel 25 on the power-transfer clutch 34 by bolt 27 and cover 26 takeoff output.Axis 30 is fixed the position by bearing 2 and bearing 32.When using manpower to drive tread plate 39, manpower is just passed on the power-transfer clutch 28 by key 29 by axis 30, by spiral shell inspection 27 and axle sleeve 26, manpower is passed on the sprocket wheel 25, thus manpower is exported.Because power-transfer clutch 28 and power-transfer clutch 34 are connected as one and have formed a special clutch: when electronic, the tread plate 39 on the axis 30 can be motionless, also can arbitrarily rotate; When manpower drives tread plate 39, can not make that motor rotates thereupon.One breach (A) and installation foot (B) are arranged, so that be installed on the vehicle on support 15.
The utility model has multiple utilization example: example sees Fig. 3, and example two is seen Fig. 4.In above-mentioned two embodiment, electric motor car driver all is installed in the middle and lower part of electric assisted bicycle vehicle frame.
Compact conformation of the present utility model is reasonable, and dependable performance is convenient to install, for ease of maintenaince, good looking appearance, practical, be the desirable upgraded product of bicycle.
