Technical Field
The invention relates to an automatic starting and stopping device of an automobile engine.
Background
The traditional automobile engine does not have an automatic start-stop function, the oil consumption and the exhaust emission are large, the emission pollution is more, and when the traditional engine is started, the structure of a starting device is unstable, so that a vehicle body has a pause feeling, and the smoothness of an automobile is reduced; the traditional automobile generator and the traditional starter are generally arranged separately, so that the structure is complex and the cost is high; when the engine stops, a certain nearby cylinder cannot be in a proper working stroke, and the cylinder is not easy to ignite successfully when the engine is restarted, so that the load of the starter is increased, and the service life of the starter is shortened.
Disclosure of Invention
The invention aims to provide an automatic starting and stopping device of an automobile engine aiming at the defects in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: an automatic start-stop device of an automobile engine comprises a crankshaft, wherein the output end of the crankshaft is connected with a planet carrier in a planetary gear mechanism, and a sun gear of the planetary gear mechanism is connected with a permanent magnet rotor in a three-phase synchronous alternating current motor; the system also comprises an electronic control unit powered by a storage battery, wherein a first control end of the electronic control unit is in bidirectional communication connection with the three-phase synchronous alternating current motor, and a second control end of the electronic control unit is in bidirectional communication connection with other control units; the control output end of the electronic control unit is connected with the hydraulic control unit; the first control output end of the hydraulic control unit is connected with a hydraulic brake for braking a gear ring in the planetary gear mechanism, and the second control output end of the hydraulic control unit is connected with a hydraulic clutch for engaging and disengaging a sun gear and the gear ring in the planetary gear mechanism
The invention has the beneficial effects that: (1) the invention is integrated with the starter, simplifies the structure, reduces the cost, greatly reduces the oil consumption and the exhaust emission, improves the economy of the automobile and reduces the emission pollution; (2) the planetary gear mechanism is in a normally meshed structure, and the engine is not subjected to pause and frustration when being started, so that the smoothness of the automobile is improved; (3) the generator and the starter are integrated, so that the structure is simplified, and the cost is reduced; (4) the starter adopts a three-phase synchronous alternating current motor, so that better starting performance is achieved; (5) when the engine stops, a certain nearby cylinder is in a proper working stroke, and the cylinder is ignited successfully when the engine is restarted, so that the load of the starter is lightened, the service life of the starter is prolonged, and the engine is started more easily and smoothly.
Drawings
Fig. 1 is a schematic diagram of the working principle of the present invention.
Detailed Description
Fig. 1 shows an automatic start-stop device of an automobile engine, which comprises a crankshaft 1, wherein the output end of the crankshaft 1 is connected with a planet carrier 3 in a planetary gear mechanism, and a sun gear 6 of the planetary gear mechanism is connected with a permanent magnet rotor 8.1 in a three-phase synchronous alternating current motor 8; the system also comprises an electronic control unit powered by a storage battery, wherein a first control end of the electronic control unit is in bidirectional communication connection with the three-phase synchronous alternating current motor, and a second control end of the electronic control unit is in bidirectional communication connection with other control units; the control output end of the electronic control unit is connected with the hydraulic control unit; a first control output of the hydraulic control unit is connected to a hydraulic brake 2 for braking a ring gear 4 in the planetary gear set, and a second control output is connected to a hydraulic clutch 7 for engaging and disengaging a sun gear 6 and the ring gear 4 in the planetary gear set. The planetary gear mechanism is mainly composed of a planet carrier 3, a ring gear 4, a planetary gear 5 and a sun gear 6. The three-phase synchronous alternating current motor 8 mainly comprises a permanent magnet rotor 8.1 and a stator 8.2.
When the automobile normally runs, the electronic control unit controls the hydraulic control unit to enable the hydraulic clutch to be combined, the crankshaft drives the planetary gear mechanism to drive the permanent magnet rotor to rotate, the three-phase synchronous alternating current motor is in a working state of the generator, the storage battery is charged through rectification of the electronic control unit, and the hydraulic brake does not brake at the moment.
When the automobile runs in a red light or is plugged, when the air conditioner is not started, the electric quantity of the storage battery, the brake vacuum and the water temperature of the engine reach normal values, the driver steps on the brake pedal, the control system can automatically control the engine to be flamed out, and a nearby cylinder is just enabled to be in a proper working stroke at the flameout time point. When the engine needs to be restarted, as long as a driver releases a brake pedal, the electronic control unit controls the three-phase synchronous alternating current motor to work and controls the hydraulic control unit to brake the hydraulic brake, the hydraulic clutch is separated at the moment, the three-phase synchronous alternating current motor drives the engine to ignite a certain cylinder in a proper working stroke, the engine is ignited successfully, after the engine is started successfully, the three-phase synchronous alternating current motor is converted into a power generation working state, and the brake and the hydraulic clutch are released from combination by the hydraulic brake.
When at least one of the electric quantity of the air conditioner or the storage battery is started, the brake vacuum and the water temperature of the engine does not reach a normal value, the automatic starting and stopping device of the engine cannot automatically control the engine to start the engine to flameout.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
