Abstract
The utility model discloses a transmission system of an electric automobile, which comprises a drive axle power input device, a transmission system output device and a transmission shaft. The transmission system of the electric automobile is characterized in that the central line of a transmission system output shaft of the transmission system output device is nonparallel to the central line of a drive axle power input shaft of the drive axle power input device. In the transmission system of the electric automobile, the central line of the transmission system output shaft and the central line of a drive axle power input flange can form a certain angle, thereby making the arrangement of the transmission system more flexible and increasing the peripheral space of a power system and the transmission system while guaranteeing the constant speed drive characteristic of the transmission system.
Description
Technical field
The utility model relates to a kind of electronlmobil, especially a kind of transmission system of electric automobile.
Background technology
The driving system of general battery-driven car is with reference to the layout of traditional fuel combustion vehicle, and driving system output shaft line of centers becomes to be arranged in parallel with drive axle power input shaft line of centers, to guarantee the constant speed drive characteristic of driving system.Because need to guarantee being arranged in parallel of driving system, the installation site of power system and driving system is limited to, and causes power system and driving system periphery to be limited to.
The utility model content
The utility model purpose is: provide a kind of simple in structure, easy to use, when guaranteeing driving system constant speed drive characteristic, make driving system arrange transmission system of electric automobile more flexibly.
The technical solution of the utility model is: a kind of transmission system of electric automobile, comprise drive axle power input device, driving system output unit and transmission shaft, it is characterized in that the drive axle power input shaft line of centers of the driving system output shaft line of centers of described driving system output unit and described drive axle power input device is not parallel.
Further, the angle of described driving system output shaft line of centers and the projection line of center transmission shaft line on perpendicular is α 3, the angle of described drive axle power input shaft line of centers and the projection line of center transmission shaft line on perpendicular is α 4, α 3=α 4; The angle of described drive axle power input shaft line of centers and the projection line of center transmission shaft line on horizontal surface is α 1, and the angle of described driving system output shaft line of centers and the projection line of drive axle power input shaft line of centers on horizontal surface is α 2, α 2=2 α 1.
The utility model has the advantages that:
Driving system output shaft center and drive axle power input flange line of centers can have a certain degree, and when guaranteeing driving system constant speed drive characteristic, it is more flexible to make driving system arrange, has increased power system and driving system peripheral space.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a transmission system of electric automobile front view of the present utility model.
Fig. 2 is a transmission system of electric automobile birds-eye view of the present utility model.
Wherein: 1 drive axle power input shaft line of centers; 2 driving system output shaft line of centerss; 3 center transmission shaft lines.
The specific embodiment
Embodiment: transmission system of electric automobile as shown in Figure 1 and Figure 2, comprise drive axle power input device, driving system output unit and transmission shaft, the driving system output shaft line of centers 3 of driving system output unit and the drive axle power input shaft line of centers 1 of drive axle power input device are not parallel.Driving system output shaft line of centers 2 is α 3 with the angle of the projection line of center transmission shaft line 3 on perpendicular, and drive axle power input shaft line of centers 1 is α 4 with the angle of the projection line of center transmission shaft line 3 on perpendicular, α 3=α 4; Drive axle power input shaft line of centers 1 is α 1 with the angle of the projection line of center transmission shaft line 3 on horizontal surface, and driving system output shaft line of centers 2 is α 2 with the angle of the projection line of drive axle power input shaft line of centers 1 on horizontal surface, α 2=2 α 1.More than the system of Bu Zhiing is when guaranteeing driving system constant speed drive characteristic, and it is more flexible to make driving system arrange again, has increased power system and driving system peripheral space.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
