Description
[technical field]
The utility model belongs to vehicle drive system technical field, particularly relates to the automatic transmission case technical field of vehicle drive system, specifically refers to a kind of self shifter electric vehicle gear box.
[background technique]
Pure electric vehicle is a kind of new energy traffic tool of alternative traditional combustion engine automobile.Current most of electric vehicle transmission only possesses a gear, and an existing this gear electric motor car exists following technical disadvantages:
1) speed ratio of a gear is difficult to the requirement ensureing Automobile Maximum climbable gradient, maximum speed and maximum acceleration;
2) when automobile high-speed cruises (speed per hour is greater than 100 kilometers/hour), motor and gear rotational speed close to or exceed 10,000 turns per minute.The accuracy of manufacturing of so high rotating speed to bearing and gear requires very high, greatly will improve fabricating cost;
3) when motor speed is close to 10,000 turns per minute, efficiency rating value relative to moment of torsion greatly reduces, and noise greatly improves simultaneously, and transmission system part life greatly reduces.
So people start again to make improvements, and slowly produce the electric motor car of many gears, but there is again motor rotor rotary inertia greatly in this many gears electric motor car, and smooth gear shifting is poor, the problem that during gearshift, power often interrupts.
Given this, be necessary to provide a kind of new self shifter electric vehicle gear box to overcome above-mentioned defect in fact.
[model utility content]
The purpose of this utility model is to provide a kind of simplicity of design, can realizes the self shifter electric vehicle gear box of level and smooth gearshift.
To achieve these goals, the utility model provides a kind of self shifter electric vehicle gear box, described electric vehicle gear box comprises casing, the main drive shaft, the output shaft parallel with main drive shaft, described main drive shaft and the output shaft that be provided with main drive motor in casing, extend from main drive motor are provided with engageable gear train, described main drive shaft is also provided with gearshift, angular position sensor and ECU (Electrical Control Unit), and at least one free end of described output shaft is coaxial with small electromotor.
One as the utility model self shifter electric vehicle gear box is improved, and described engageable gear train comprises five pairs of main driven gears, five gears of the corresponding electric motor car of its difference.
One as the utility model self shifter electric vehicle gear box is improved, described gearshift comprises shift motor, block selecting motor and the block selecting axle for connecting shift motor and block selecting motor, and described shift motor is connected to the synchronizer between two driving gears by selector fork.
One as the utility model self shifter electric vehicle gear box is improved, and described angular position sensor is arranged at block selecting the tip of the axis, and described angular position sensor is monitored the position of selector fork in real time and its position signal is fed back to ECU (Electrical Control Unit).
One as the utility model self shifter electric vehicle gear box is improved, and when selector fork departs from synchronizer, small electromotor starts.
Compared with prior art, the benefit that the utility model self shifter electric vehicle gear box has is: the 1) selection of many gears, can meet the requirement of Automobile Maximum climbable gradient, maximum speed and maximum acceleration; 2) angular position sensor is monitored the position of selector fork in real time and its position signal is fed back to ECU (Electrical Control Unit), and when selector fork departs from synchronizer, small electromotor starts, and during the startup supplementing motor can ensure to shift gears, power does not interrupt.
[accompanying drawing explanation]
Fig. 1 is the utility model self shifter electric vehicle gear box structural representation;
[embodiment]
In order to make, the purpose of this utility model, technological scheme and Advantageous Effects are more clear to be understood, below in conjunction with the drawings and specific embodiments, is further elaborated to the utility model.Should be understood that, the embodiment described in this specification is only used to explain the utility model, is not to limit the utility model.
Please refer to shown in Fig. 1, a kind of self shifter electric vehicle gear box, described electric vehicle gear box comprises casing, is provided with main drive motor 10, the main drive shaft 48 extended from main drive motor 10, the jack shaft 45 parallel with main drive shaft 48 and the output shaft 20 that extends to form from jack shaft 45 in casing.Correspondingly respectively on described main drive shaft 48 and output shaft 20 be provided with engageable gear train, gearshift, angular position sensor 47 and ECU (Electrical Control Unit), at least one free end of described output shaft is coaxial with small electromotor 30.The two ends of main drive shaft 48 are installed on casing by spring bearing 46.
Engageable gear train comprises five pairs of main driven gears, five gears of the corresponding electric motor car of its difference.Gearshift comprises shift motor 42, block selecting motor 44 and the block selecting axle 441 for connecting shift motor 42 and block selecting motor 44, and described shift motor 42 is connected to the synchronizer 41 between two driving gears by selector fork 421.Angular position sensor 47 is arranged at the end of block selecting axle 441, and described angular position sensor 47 is monitored the position of selector fork 421 in real time and its position signal is fed back to ECU (Electrical Control Unit).
The utility model self shifter electric vehicle gear box is when shifting gears, the selector fork 421 be arranged on synchronizer 41 drives selector fork 421 to rotate by block selecting motor 44 and realizes gearshift, angular position sensor 47 is monitored the position of selector fork in real time and its position signal is fed back to ECU (Electrical Control Unit), ECU (Electrical Control Unit) adjusts the driving force of drive motor 10 according to the signal received thus realizes level and smooth gearshift, when selector fork 421 departs from synchronizer, small electromotor 30 starts, thus ensures the gearshift not interrupting power.
The utility model self shifter electric vehicle gear box, be not restricted to described in specification and mode of execution, therefore additional advantage and amendment can easily be realized for the personnel of familiar field, therefore when not deviating from the spirit and scope of the universal that claim and equivalency range limit, the utility model is not limited to specific details, representational equipment and illustrates here and the examples shown described.
