In order to reach above-mentioned technical purpose, the utility model embodiment provides in a kind of electric car and is flexibly connected multi gear
Position speed changing structure, flexible connection multi gear position speed changing structure includes: in the electric car
Motor a comprising line shaft；
Clutch comprising flywheel, clutch case, pressing plate, frictional disk, spring, clutch pedal and connecting rod, line shaft
Coaxially connected with flywheel, clutch case is connect with flywheel, surrounds to form a clutch chamber, and it is intracavitary that pressing plate is arranged in clutch, passes through bullet
Spring is connect with clutch case, and frictional disk is arranged in that clutch is intracavitary and abut with pressing plate, and connecting rod one end connects clutch pedal, another
End connection pressing plate；
Change gear box a comprising input shaft, it is intracavitary that input shaft one end extends to clutch, and coaxially connects with frictional disk
It connects.
Compared with prior art, the utility model has the following beneficial effects: it is flexible in the electric car of the utility model
The flat of motor energy transmission can be improved using the multi-speed gear box structure of flywheel flexible connection in connection multi gear position speed changing structure
It is pliable, motor can be made to remain at the work of best torque output interval using multi-speed gear box, not only reduce output
Kinetic equation loss promotes the power output efficiency of motor, moreover it is possible to improve the ride experience of passenger.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that multi gear position speed changing structure is flexibly connected in electric car provided by the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Referring to Figure 1, Fig. 1 is the structure that multi gear position speed changing structure is flexibly connected in electric car provided by the utility model
Schematic diagram.
It includes: motor 1, clutch and change gear box 3 that multi gear position speed changing structure is flexibly connected in electric car.
Motor 1 includes a line shaft 11.The effect of motor is to convert mechanical energy for the electric energy of power supply, passes through transmission
Device or direct drive of wheel and equipment.But most start using dc motor, dc motor is due to having commutation fire
Flower, power is small, low efficiency, the big problem of maintenance work amount.With the development of electric machines control technology, gradually by direct current
Replaced brushless motor, switched reluctance motor and AC asynchronous motor.
Clutch includes flywheel 21, clutch case 22, pressing plate 23, frictional disk 24, spring 25, connecting rod 26 and clutch
Pedal 27.Line shaft 11 and flywheel 21 are coaxially connected, and clutch case 22 is connect with flywheel 21, surround to form a clutch chamber.Pressing plate
23 to be arranged in clutch intracavitary, is connect by spring 25 with clutch case 22.Frictional disk 24 is also arranged in that clutch is intracavitary and and pressing plate
23 parallel abuttings.26 one end of connecting rod connects clutch pedal 27, and the other end connects pressing plate 23.
Change gear box 3 includes an input shaft 31 and an output shaft 32.It is intracavitary that 31 one end of input shaft extends to clutch, and
It is coaxially connected with frictional disk 24.
When clutch pedal 27 in the raw when, the elastic force of spring 25 makes 23 pressing friction disk 24 of pressing plate, electronic
The line shaft 11 of machine 1 drives flywheel 21 to rotate, and flywheel 21 is rotated by clutch case 22 with dynamic pressure plate 23, in the effect of frictional force
Under, pressing plate 23 drives frictional disk 24 to rotate, and frictional disk 24 drives the input shaft 31 of change gear box 3 to rotate, and passes through transmission gear
The chronotropic action of case 3, output shaft 32 export suitable revolving speed.When needing to shift gears, driver steps on clutch pedal 27, connecting rod 26
Band 23 compressed spring 25 of dynamic pressure plate, so that pressing plate 23 is separated with friction plate 24, so as to the shift of change gear box 3.
Implement the utility model embodiment, has the following beneficial effects: in the electric car of the utility model and be flexibly connected
The ride comfort of motor energy transmission can be improved using the multi-speed gear box structure of flywheel flexible connection for multi gear position speed changing structure,
Motor can be made to remain at the work of best torque output interval using multi-speed gear box, not only reduce output power damage
Consumption, promotes the power output efficiency of motor, moreover it is possible to improve the ride experience of passenger.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
