7. a kind of method of work of electric automobile rubber belt type energy-accumulated electric switched machine assembly according to claim 2, its feature
It is：
Comprise the following steps：
A, Brake energy recovery process
When being braked during electric automobile advance, the first electromagnetic clutch (41) and electromagnetic brake (30) are in be powered and engaged
Working condition, the second electromagnetic clutch (42) no power is in off working state, is connect because the first electromagnetic clutch (41) is powered
Close so that the first electromagnetic clutch (41) drive end is bonded together with the first electromagnetic clutch (41) driven end, the 3rd gear
Axle (40f) is rotated together with the 5th gear shaft (40h)；
Inertia force produced by electric vehicle brake is inputted by motor output shaft (100A), through gear (10), the
Three gears (40a), the first electromagnetic clutch (41), the 5th gear (40c) and the second idler gear (40d) are transferred to accumulation of energy conversion
Unit (20), drives ball-screw (20a) rotation, because ball nut (20b), sliding panel (20c), guide block (20d) three connect
One is connected in, and guide block (20d) can only be for linear motion along guide rail (20e), so ball nut (20b) is together with sliding panel
(20c) is for linear motion along guide rail (20e) to the direction away from fixed plate (20g) together, makes to be located at sliding panel (20c) and fixed
Elastic rubber band (20f) stretching between plate (20g), the kinetic energy of electric automobile is stored into the form of rubber strip elastic potential energy
In elastic rubber band (20f)；
B, braking energy release process：
When electric automobile discharges accumulator energy in starting-up process, the second electromagnetic clutch (42), electromagnetic brake (30)
It is powered, electromagnetic brake (30), which is in, releases braking operation state, ball-screw (20a) is rotated, while first
The engagement of electromagnetic clutch (41) no power is in off working state, is engaged because the second electromagnetic clutch (42) is powered so that the
Two electromagnetic clutch (42) drive end is bonded together with the second electromagnetic clutch (42) driven end, the 4th gear shaft (40g) with
6th gear shaft (40j) is rotated together；
Under elastic rubber band (20f) pulling force effect, ball nut (20b) is together with sliding panel (20c) to close to fixed
The direction of plate (20g) is for linear motion along guide rail (20e), makees ball-screw (20a) opposite with Brake energy recovery process
Rotary motion, ball-screw (20a) is by power through the second idler gear (40d), the 6th gear (40e), the second electromagnetic clutch
(42), the 4th gear (40b), the 3rd gear (40a), gear (10) are transferred on motor output shaft (100A), this
When, the direction of rotation of accumulation of energy converting unit (20) release accumulation of energy is identical with the direction of rotation of motor output shaft (100A), accumulation of energy
The elastic potential energy of storage is converted into the kinetic energy of electric automobile in converting unit (20), electric automobile during traveling is driven, until releasing completely
Untill the elastic potential energy for putting elastic rubber band (20f) storage；
C, braking energy keep process：
When vehicle is in non-brake energy recovery process or in non-brake energy release process, the first electromagnetic clutch
(41), the second electromagnetic clutch (42) and electromagnetic brake (30) no power, electromagnetic brake (30) is in on-position, rolling
Ballscrew (20a) does not rotate, and the energy of elastic rubber band (20f) keeps constant.
