Abstract
Description
Technical Field
[0001] The utility model relates to the field of motor supporting devices, in particular to a driving machine with an inertia wheel. Background Art
[0002] When the motor of a new energy vehicle is running, the on-board battery provides electricity to the motor to drive the output shaft of the motor to rotate. When the power supply to the motor stops, the new energy vehicle will continue to move forward a certain distance due to inertia, and the new energy vehicle will generate electricity by driving the output shaft of the motor to rotate through the transmission mechanism.
[0003] However, when the motor is powered off and performs the above-mentioned power generation steps, voltage and current are generated in the motor. The voltage and current will generate a magnetic field in the motor. The magnetic field will produce resistance to the output shaft of the motor during rotation, making the gliding distance of the new energy vehicle short, resulting in very low motor power generation efficiency and poor conversion of mechanical energy into electrical energy.

[0012] The beneficial effects of the driving machine with an inertia wheel disclosed in the utility model are:
[0013] After the external new energy vehicle releases the ignition switch and enters the coasting state, it is necessary to increase the rotational inertia of the motor's output shaft, start the electromagnetic coil to attract the metal disk, so that the metal disk pulls the elastic ring to elastically deform, and the metal disk touches the counterweight wheel.

[0029] Please refer to Figure 3-Figure 6 .
[0030] An electromagnetic coil 11 is provided on the other end of the bracket 1. In this embodiment, the electromagnetic coil 11 is preferably annular, and the electromagnetic coil 11 is fixedly connected to the bracket 1 by bolts.
[0031] A counterweight wheel 12 is rotatably connected to the bracket 1; an annular groove 121 is provided on the counterweight wheel 12, and the annular groove 121 can reduce the thickness of a part of the counterweight wheel 12, and a through groove is provided at the bottom of the annular groove 121, and the through groove passes through the counterweight wheel 12, and the electromagnetic coil 11 is located in the annular groove 121, and the electromagnetic coil 11 can absorb the metal disk 324 through the thinner part of the counterweight wheel 12, and the through groove can enhance the adsorption force of the electromagnetic coil 11 on the metal disk 324, and the other end of the bracket 1 is sleeved with a first bearing 122, and the other end of the bracket 1 is clamped with a first retaining spring, and the first retaining spring fixes the first bearing 122 to the bracket 1, and the counterweight wheel 12 is sleeved on the outer ring of the first bearing 122, and the counterweight wheel 12 is coaxial with the first bearing 122, and the counterweight wheel 12 is rotatably connected to the bracket 1 through the first bearing 122.
[0032] The main shaft 3 passes through the counterweight wheel 12, and the main shaft 3 is coaxial with the counterweight wheel 12. A second bearing 311 is embedded in the bracket 1, and the inner ring of the second bearing 311 is sleeved on the outside of the main shaft 3. The other end cover of the bracket 1 is provided with a protective shell 13, and the main shaft 3 passes through the protective shell 13. A third bearing 312 is embedded in the protective shell 13, and the inner ring of the third bearing 312 is sleeved on the outside of the main shaft 3. The second bearing 311 and the third bearing 312 are both coaxial with the main shaft 3; a second retaining spring and a third retaining spring are sleeved on the main shaft 3, and the second bearing 311 and the third bearing 312 are limited between the second retaining spring and the third retaining spring, so that the main shaft 3 can be restricted by the second retaining spring and the third retaining spring to rotate on the bracket 1.
[0033] Please refer to Figure 3-Figure 5 and Figure 7 、 Figure 8 .
[0034] A friction wheel 32 is provided on the main shaft 3. The counterweight wheel 12 and the friction wheel 32 are both located in a protective shell 13. The protective shell 13 can prevent external foreign matter from approaching the counterweight wheel 12 and the friction wheel 32 and affecting their operation. The friction wheel 32 is composed of a connecting wheel 321, an elastic ring 322 and a connecting wheel 323.
[0035] The cam 322 is fixed on the cam 323 and is fixed on the cam 324. When the cam 323 is in a state of being worn, the cam 322 is loosened and the washer 323 is tightened.
[0036] Furthermore, the counterweight wheel 12 is located between the electromagnetic coil 11 and the metal disk 324, and the metal disk 324 is close to the through slot. In this embodiment, the distance between the metal disk 324 and the counterweight wheel 12 is preferably 1MM, so that under the adsorption of the electromagnetic coil 11, the metal disk 324 only needs to move 1MM to contact the counterweight wheel 12. The metal disk 324 pulls the elastic ring 322 to perform elastic deformation with a small amplitude, thereby preventing the elastic ring 322 from detaching from the connecting wheel 321.
[0037] By passing current through the electromagnetic coil 11, the electromagnetic coil 11 attracts the metal disk 324 to contact the counterweight wheel 12, and the main shaft 3 uses the friction between the metal disk 324 and the counterweight wheel 12 to drive the counterweight wheel 12 to rotate synchronously. The method of using friction to drive the counterweight wheel 12 to rotate can reduce the impact force brought to the motor 2 when the counterweight wheel 12 and the main shaft 3 are instantly started; by disconnecting the current of the electromagnetic coil 11, the metal disk 324 loses the adsorption of the electromagnetic coil 11, and the metal disk 324 is pulled back by the elastic ring 322 away from the counterweight wheel 12, allowing the counterweight wheel 12 and the main shaft 3 to rotate separately.
[0038] Please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 7 .
[0039] When the motor 2 is just started, it needs to consume more electric energy. At this time, the electromagnetic coil 11 is turned off. When the metal disk 324 loses the adsorption of the electromagnetic coil 11, the elastic ring 322 pulls the metal disk 324 to reset, and the main shaft 3 will not drive the counterweight wheel 12 to rotate synchronously, so that the output shaft of the motor 2 can be started more easily, and the electric energy consumption of the motor 2 at the time of just starting can be reduced; after the motor 2 is started, the electromagnetic coil 11 starts to run, and the metal disk 324 approaches and contacts the counterweight wheel 12 under the adsorption of the electromagnetic coil 11, and the metal disk 324 pulls the elastic ring 322 to elastically deform, and the main shaft 3 drives the counterweight wheel 12 to rotate synchronously through the friction between the metal disk 324 and the counterweight wheel 12; when it is necessary to increase the rotational inertia of the output shaft of the motor 2, the counterweight wheel 12 can intervene and rotate synchronously; when it is not necessary to increase the rotational inertia of the output shaft of the motor 2, the friction wheel 32 is disconnected from the counterweight wheel 12, so that the rotational inertia of the counterweight wheel 12 will not be transmitted to the output shaft of the motor 2;
[0040] When the external new energy vehicle enters high-speed driving, the electromagnetic coil 11 starts to operate, and the rotational inertia of the counterweight wheel 12 is transmitted to the output shaft of the motor 2. Driven by the rotational inertia of the counterweight wheel 12, the operating efficiency of the motor 2 is improved while increasing the gliding distance of the external new energy vehicle. Moreover, when the external new energy vehicle releases the ignition switch and stops supplying power to the motor 2, the rotational inertia of the counterweight wheel 12 drives the output shaft of the motor 2 to rotate for a longer time, thereby improving the effect of the motor 2 in converting mechanical energy into electrical energy.
[0041] When the external new energy vehicle enters a hilly section, the electromagnetic coil 11 starts to run, and the rotational inertia of the inertia wheel drives the output shaft of the motor 2 to rotate, so that the output shaft of the motor 2 increases its power without increasing its speed output, thereby improving the torque of the external new energy vehicle when it is moving. The increase in the torque of the external new energy vehicle can play a stabilizing role when the car encounters water and slips.
[0042] The utility model provides a driving machine with an inertia wheel. After the external new energy vehicle releases the power switch and enters the coasting state, it is necessary to increase the rotational inertia of the output shaft of the motor, start the electromagnetic coil to attract the metal disk, so that the metal disk pulls the elastic ring to elastically deform, and the metal disk is allowed to contact the counterweight wheel. The motor drives the main shaft to rotate, and the main shaft drives the elastic ring, the connecting wheel and the metal disk to rotate in sequence through the connecting wheel. The metal disk uses friction to drive the counterweight wheel to rotate synchronously, thereby increasing the rotational inertia of the output shaft of the motor; after the motor is powered off, the output shaft of the motor continues to rotate driven by the counterweight wheel, which increases the coasting distance of the external new energy vehicle and improves the effect of the motor in converting mechanical energy into electrical energy.
[0043] Since the motor consumes more electricity when it is just started, it is necessary to stop the operation of the electromagnetic coil. The elastic ring pulls the metal disk to reset, disconnecting the counterweight wheel from the motor output shaft so that the counterweight wheel does not affect the starting of the motor, thereby reducing the power consumption required by the motor when it is just started.
[0044] When a new energy vehicle enters a hilly section, the electromagnetic coil is activated to attract the metal disk, allowing the motor output shaft to drive the counterweight wheel to rotate synchronously. The rotational inertia of the counterweight wheel can act on the motor output shaft, increasing the torque of the motor output shaft when climbing.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
