Abstract
The utility model discloses a motor driving device of an electric vehicle, which comprises a motor (2), a speed reducing mechanism (3), a power output shaft (4) and wheel hubs (5), wherein the rear end cover of the motor (2) is fixedly provided with a left half axle (1); brake drums (6) arranged on the wheel hubs (5) are internally provided with half axle seats (9); the power output shaft (4) is installed on the half axle seats (9) by bearings (10); the half axle seats (9) are provided with a right half axle (8) extending outside the brake drums (6); braking mechanisms (7) are respectively arranged between the brake drums (6) and the half axle seats (9); and the wheel hubs (5) are installed on the power output shaft (4) by nuts (11). By adopting the structure, the motor driving device has the characteristics of compact structure, simple installation and disassembly, convenient repair and replacement, large transmission torsion, strong climbing ability, long driving mileage and the like.
Description
Technical field
The utility model relates to the motor driver of a kind of battery-driven car, particularly a kind of battery-driven car.
Background technology
Along with the development of society and the progress of science and technology, people's living standard is further enhanced, battery-driven car has been come into huge numbers of families as the traffic means of transport of environmental protection and energy saving, become the main substitute of bicycle gradually, in the vehicle, play a part very important, along with the raising of battery life and the maturation day by day of electron controls technology, the market outlook of battery-driven car are wide.
The powered version of battery-driven car mainly contains two classes at present, and a kind of is the electric wheel hub that motor and wheel hub are connected as a single entity; The weak point of its existence is the restriction that is subjected to constructional feature and principle, and complex structure, driving torque is little, hill climbing ability is poor, travelled distance is short, difficulty of processing is big, productive costs is high, and particularly motor or wheel hub damage in the time of can't repairing, and can only integral body scrap.
Another kind is that motor is installed on the vehicle frame by chain belt motor-car wheel, is replaced by electric wheel hub gradually; Be characterized in simple in structure, productive costs is low, easy to maintenance; Its weak point be chain wear big, can elongation, service life is short, driving efficiency is low, not attractive in appearance.
At the problems referred to above, many manufacturers and knowledgeable people research and develop, but do not have desirable product to emerge on market so far as yet.
Summary of the invention
For overcoming the above-mentioned disadvantage of existing battery-driven car existence, the purpose of this utility model provides a kind of compact conformation, installing/dismounting is simple, the repairing transposing is convenient, driving torque is big, hill climbing ability is strong, the electric vehicle motor actuating device of travelled distance length.
The technical scheme that its technical matters that solves the utility model adopts, it comprises motor, speed reduction gearing, power take-off shaft, wheel hub, be fixed with left half axle on the rear side housing of described motor, the semiaxis seat is installed in the brake drum on the wheel hub, power take-off shaft by bearing installation on the semiaxis seat, the semiaxis seat is provided with the right axle shaft that stretches out brake drum, is provided with braking mechanism between brake drum and semiaxis seat.
First kind of mounting means of the utility model wheel hub, described wheel hub is installed on the power take-off shaft by nut.
Second kind of mounting means of the utility model wheel hub is equipped with flange by nut on the described power take-off shaft, and wheel hub is fixed on the flange.
After adopting said structure, the utility model has following advantage and effect: the one, when the wheel hub damage can't be repaired, motor can be dismantled reuse, when motor damages, wheel hub can be dismantled reuse, can be by requirement repairing or transposing separately, easy accessibility, economic loss can be dropped to minimumly, saving of work and time is laborsaving again; The 2nd, adopt this structure type of drive, driving efficiency height, driving torque is big, hill climbing ability is strong; The 3rd, braking mechanism acts directly on the semiaxis seat during brake, and mechanical wear is little, and braking effect is good.
