Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is illustrated:
As shown in Figure 1, the utility model provides a kind of electric automobile energy storage device, a large amount of kinetic energy storage during for electric automobile is braked, use during in order to starting to walk, raise speed or climb next time, concrete comprises motor 1, this motor 1 is two output shaft electric machines, its one end output shaft is connected with accumulator 2, accumulator 2 is for getting up the kinetic energy storage of motor 1, the output shaft of motor 1 other end is connected with clutch 3, described clutch 3 is connected to gearbox 4, and the car load for electric automobile is walked;
In the present embodiment, accumulator 2 comprises the flywheel 21 be set in successively on the output shaft of motor 1 one end, closes from sheet 22, platen 23 and release bearing 24, closing is fixedly installed in flywheel 21 from sheet 22, close and be provided with return spring 25 from sheet 22 both sides, platen 23 is connected with shift fork 26, and shift fork 26 is connected to and closes from pedal.The specific works principle of accumulator 2 is as follows:
When stepping on conjunction from pedal, drive platen 23 to press to from the shift fork 26 of pedal linkage by release bearing 24 to close from sheet 22 with closing, platen 23 produces frictional force with conjunction mutually from sheet 22, and rotated from sheet 22 and flywheel 21 (flywheel 21 is with dynamic circuit connector from sheet 22) with conjunction by this frictional force, now return spring 25 is pushed down by platen 23 and is in compressive state, and accumulator 2 is in thermal energy storage process; When lifting conjunction from pedal, platen 23 is separated from sheet 22 with conjunction under the drive of return spring 25, and accumulator 2 is in non-energy storage state.
Further, flywheel 21 connects the side of closing from sheet 22 and is provided with the first groove 211, closes and is all placed in described first groove 211 from sheet 22 and return spring 25.And first the width of groove 211 be more than or equal to the diameter of platen 23, when platen 23 press to close from sheet 22 time, platen 23 can be placed in described first groove 211, and interacting from sheet 22 with conjunction produces frictional force.
