Abstract
The invention relates to a double-drive speed reducer for an electric automobile. The speed reducer comprises a left speed reduction box body (1), a left speed reduction box body (2) and a middle speed reduction box body (3). By the speed reducer, the speed reducer is connected with a motor and a wheel transmission device, the electric automobile is decelerated, and special speed reduction equipment is provided for the electric automobile; and the requirements of the electric automobile on the performance and the noise of the speed reducer are met, and power transmission from the motor to a wheel is finished.
Description
Technical field
The present invention relates to a kind of speed reduction gearing, be applied to electronlmobil, be connected the two retarders that drive of the electronlmobil of realizing deceleration and differential with DC motor.
Background technology
At present, no matter international or domestic, also be in the starting stage for manufacturing and designing of electronlmobil, each main engine plants is to the performance requriements of retarder disunity also, but requiring of drive mechanism is roughly the same, promptly realizes slowing down and differential.Slowing down is one-level or double reduction, and differential is realized by diff.Because the propulsion source of electronlmobil is a wheel hub electric motor, therefore require design-calculated retarder noise low, to satisfy the low noise requirement of car load.
Summary of the invention
Purpose of the present invention is to overcome above-mentioned deficiency of the prior art exactly and a kind of low noise that can guarantee is provided, and can satisfy the two retarders that drive of electronlmobil of the torque demand of electronlmobil again.
For achieving the above object, the present invention adopts following scheme to be achieved in that the two retarders that drive of a kind of electronlmobil, comprise left deceleration box (1), left deceleration box (2), intermediate reduction gear casing (3), it is characterized in that: left deceleration box (1) is provided with left motor mount (4), and right deceleration box (2) is provided with right motor mount (5); Left input shaft (6), right input shaft (7) in the middle of a left side motor mount (4), the right motor mount (5) is provided with and can allows input shaft and motor bonded assembly axis hole; Left output shaft (8), right output shaft (9) in the middle of a left side motor mount (4), the right motor mount (5) is provided with and can allows output shaft and motor bonded assembly axis hole.Left side motor mount (4), right motor mount (5) can be installed motor.
The present invention has realized being connected of retarder and motor and wheel drive and the function that electronlmobil slows down, and a kind of retarder equipment of special use is provided for electronlmobil.The present invention adopts the combination of dual input, dual output, left and right drop-gear box individual drive, independent output, and a motor breaks down, and power system still can be worked, and has improved the dynamic property and the reliability of power system of electric automobile; Retarder adopts left and right drop-gear box integrative-structure, and it is little, in light weight to take up room, and is convenient to the retarder installation, thereby a kind of retarder equipment of special use is provided for battery-driven car.
Left and right sides motor mount is used for fixing the installation wheel hub motor, and retarder and wheel hub electric motor adopt double reduction, left and right sides mouth and wheel component direct connection by housing and adapter sleeve direct connection.Input shaft in the middle of the left and right sides motor mount is provided with and can allows input shaft and motor bonded assembly axis hole, the output shaft of the left and right sides is provided with and can allows output shaft and left and right half bonded assembly axis hole, thereby has realized making things convenient for being connected and function that electronlmobil slows down of retarder and motor and wheel drive.
The invention has the beneficial effects as follows, realized performance and the noise requirements of electronlmobil, finish by the transmission of power of electrical motor to wheel to retarder.
Description of drawings:
Fig. 1 is the invention structural representation
The specific embodiment:
Left and right sides motor mount is used for fixing the installation wheel hub motor, and retarder and wheel hub electric motor adopt double reduction, left and right sides mouth and wheel component direct connection by housing and adapter sleeve direct connection.Input shaft in the middle of the left and right sides motor mount is provided with and can allows input shaft and motor bonded assembly axis hole, the output shaft of the left and right sides is provided with and can allows output shaft and left and right half bonded assembly axis hole, thereby has realized making things convenient for being connected and function that electronlmobil slows down of retarder and motor and wheel drive.
Claims (2)
