At present, the drive configuration of most battery-driven cars normally adopts universal-joint, or chain etc. drives diff, the drive connection more complicated of this structure, stability of structure is not strong, for example chain easily takes off chain, and universal-joint is fragile, respectively organize gear is easy to generate phenomenons such as wearing and tearing, and said structure has caused loss than macro-energy because of the complexity of drive connection when work simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of power of motor waste, electric vehicle direct driving device simple in structure avoided.
The purpose of this utility model is achieved in that
A kind of direct-drive type structure of battery-driven car, it is characterized in that: comprise drive motor, retarder and the diff of linearly arranging, the motor shaft of described drive motor is connected with retarder, described motor shaft parallels with the output shaft of retarder or is positioned on the coaxial line, the output shaft of described retarder is connected with diff, in the housing that described retarder, diff are installed in drive motor is captiveed joint.
In the direct-drive type structure of above-mentioned a kind of battery-driven car, described housing is to be spirally connected by two half symmetrical housings to form, the inner gear housing that comprises differential casing and retarder, described differential casing is connected with the inner gear housing one of retarder, the described inner gear housing outside is connected with the side with the electric motor end cap coupling, offers bolt hole on the side and fixes by bolt and electric motor end cap.
In the direct-drive type structure of above-mentioned a kind of battery-driven car, described retarder is epicyclic reduction gear, the center gear of described motor shaft connection reducer, the center of described planetary gear carrier is connected with reducer output shaft, and the driving gear that drives the diff driven gear is installed on the described reducer output shaft.
The utility model outstanding and beneficial technical effects compared to existing technology is:
The utility model has adopted driven gear or drive motor that drive motor is directly driven in the diff directly to drive retarder, retarder drives diff, driven gear is a transmission left side again, the right axle shaft gear is realized driving battery-driven car and is travelled, this structure has been avoided the degradation of energy that causes because of the drive connection complexity, make integral structure more simple, the transmission speed of response is fast, simultaneously that the inner gear housing of differential casing and retarder is one-body molded, the utility model novel structure, drive connection is simple and clear, improved the Occupation coefficient of transmission speed of response and energy when having saved productive costs, product is durable in use, greatly improved service life.
