Inertial engine with an electric drive
The invention relates to traction engines of vehicles equipped with electric batteries. Inertial engine contains kinematically associated with the transmission of the vehicle, the flywheel housing, which has a rechargeable battery. The latter is connected with an electric motor designed to rotate the flywheel housing. The difference between the proposed device is known is that the motor is connected with the flywheel housing kinematic chain that transmits motion through frictional forces in the bearing. The power of the motor is chosen with regard to overcome the frictional forces in the above-mentioned bearing. The parameters mentioned bearing, such as the type, dimensions, materials, parts, lubricants and others, are selected from the conditions optimal resistance to its rotation. The proposed inertial engine is characterized by a simplified construction and increased operating time between charges of the battery. 2 C.p. f-crystals, 1 Il. The invention relates to transport and can be used on vehicles with a power source used, accumulates is tentatively produce mutual alignment of shafts of the mechanical inertia of the battery and the charger, connect them when not included the charger and after alignment of their velocities include charger (Ed. mon. THE USSR 615302, F 16 H 33/02, 1976).The disadvantage of this method and device for its realization is the fact that the vehicle is driven only by the energy accumulated by the inertial battery during recharging. The result is a small distance, which is able to pass such vehicle, and the necessity of its location constantly in the vicinity of stations with the above charger.Known inertial drive containing spermaholic kinematically associated with the output shaft of the Autonomous drive, made in the form of a detonation combustion engine with piston hydraulic cavities provided with a turbine is installed on the output shaft (RF Patent 2078252, F 03 G 3/08, 1994).The disadvantage of this engine is the complexity of its design, the unreliable due to problems with ensuring the tightness of the highways of the working fluid and non-compliance ecologists the VA, containing an electric motor with internal fixed stator and outer rotor with the coil anchor bearing flywheel housing, which contains a battery, the supply anchor the rotor winding (Ed. mon. THE USSR 1364508, B 60 L 11/16, 1985).The disadvantage of this motor is that the power of the motor must not be much less than the power of the electric drive, which uses the battery to mechanical energy of the flywheel. This is because the rotation of the rotor occurs through the interaction of magnetic fields, which do not allow significant mutual slippage.The considerable power of the motor reduces the service life of the batteries and, therefore, the mileage of the vehicle from the charging to the charging of these batteries.The last analogue is taken as a prototype, since most of its essential features the same characteristics of the proposed inertial engine.The purpose of the invention is to simplify the design and increase the time of operation of the inertial engine with an electric drive between charges of the battery.Specified the config with the transmission of the vehicle, the flywheel housing, in which you installed rechargeable battery is connected with an electric motor designed to rotate the flywheel housing, the electric motor is connected with the flywheel housing kinematic chain that transmits motion through friction in the bearing, the major part of the power of the motor is chosen with regard to overcome the frictional forces in the above-mentioned bearing.The present invention is illustrated in the drawing, where Fig.1 is a schematic diagram of one possible embodiment of the inertia of the engine with an electric drive.Inertial engine with an electric drive includes a frame 1, on which through the thrust ball bearing 2 mounted sleeve 3 with the bore under the thrust ball bearing 4 and the ring gear 5. On the bearing 4 has a housing 6 of the flywheel mounted on its periphery batteries 7. The flywheel housing through the shaft 8 is connected with the transmission of the vehicle (not shown). The electric motor 9 mounted on frame 1, and a toothed wheel 10 is engaged with the ring gear 5 of the sleeve 3. Current from the battery 7 is supplied to the motor through the brushes 11 and mounted on the housing flywheel the conditions optimal resistance to its rotation.The power of the electric motor 9 is selected so that the bulk of it was not much more than is necessary to overcome the frictional forces in the bearing 4.Works inertial engine with electric drive are as follows.In position, when the shaft 8 is not connected with the transmission of the vehicle (squeezed the clutch in neutral position the gear lever), rechargeable battery 7 are connected with the motor through the brushes 11 and collector rings 12, and the motor starts to rotate, transmitting the rotation of the toothed wheel 10 on the ring gear 5 of the sleeve 3. Last, rotating on the bearing 2, rotates installed in the boring part of the bearing 4, which passes through friction rotating part of the bearing 4 mounted in the bore of the flywheel housing 6. The housing of the flywheel 6 is gradually unwound, gaining momentum and storing the kinetic energy required for rotation of the wheels 13 of the vehicle.When turning on the clutch and gearbox, the vehicle begins to move, and the promotion of the flywheel continues through friction in the bearing 4. Due to the low power of the motor 9 and nautically circuit, transmitting motion through frictional forces in the bearing 4, the engine speed remain constant, it is not overloaded, and to the flywheel housing is continuously fed kinetic energy needed to propel the vehicle.Compared with conventional motors, where rechargeable batteries are an additional load, which reduces the amount of payload in the proposed engine battery, as part of the flywheel, be a useful cargo. It is also possible the connection to the flywheel generator, which is used to recharge batteries. The proposed inertial engine with electric drive can be widely used in electric vehicles, especially for movement in an urban environment, when there are frequent and long interruptions, unwanted noise and pollution of the exhaust gases.
