Abstract
The utility model discloses a motor drive assembly for an electric vehicle. The motor drive assembly is characterized in that a hub is fixed to a main shaft through a shaft sleeve in the center; one side surface of the hub is fixedly provided with a concentric ring gear; an inner round surface of the ring gear is provided with gear teeth; a direct-current motor is disposed on the one side where the ring gear of the hub is located; an output shaft of the direct-current motor is provided with a drive gear that is engaged with the ring gear; and the direct-current motor is fixed onto the main shaft through a motor base. The motor drive assembly is simple in structure and small in energy loss, has a function of deceleration, enables the electric vehicle to have larger power and stable starting, reduces the power consumption of the motor, and is easy to maintenance and overhaul.
Description
Technical field
The utility model relates to electric automobiles, relates in particular to a kind of electric vehicle motor and drives assembly.
Background technology
At present, the wheel hub motor that adopts on the electric bicycle is generally the permanent magnetic DC low-speed motor, and its motor speed is low, and power consumption is big, because it does not establish reducing gear usually, so differential force.Also have the wheel hub motor inside in the technical scheme to be provided with epicyclic reduction gear unit, its structure is comparatively complicated, the cost height, and energy consumption is higher during running, not by penetration and promotion.In addition, the wheel hub motor that present electric motor car adopts is owing to design for one with wheel hub, and the motor part can not be taken off separately, brings very big inconvenience for maintenance of motor, maintenance.
The utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of energy consumption low, and power is big, and the simple electric vehicle motor of reducing gear drives assembly.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of electric vehicle motor drives assembly, comprise direct current machine and wheel hub, it is characterized in that: wheel hub is fixed on the main shaft by the axle sleeve at center, fixedly there is a concentric ring gear wheel hub one side, and the ring gear inner headed face is provided with the gear teeth, and a side at the ring gear place of wheel hub is provided with a direct current motor simultaneously, the output shaft of direct current machine is provided with the driven wheel with the ring gear engagement, and direct current machine is fixed on the main shaft by motor cabinet.
The utlity model has following beneficial effect: it is simple in structure, has deceleration, makes electric motor car power bigger, and starting has steadily reduced the power consumption of motor; Its deceleration realizes that by driven wheel and wheel hub transmission is simple, and energy loss is little; Simultaneously, because direct current machine is positioned at wheel hub one side, convenient disassembly is easy to safeguard and maintenance.
