Description

Technical Field

[0001] This invention relates to the field of gasoline engine starting system technology, and in particular to a plug-in hybrid gasoline engine starter. Background Technology

[0002] In the field of gasoline engine starting systems, the starter, as a core power output component, directly affects the starting reliability and service life of the gasoline engine. Existing gasoline engine starters mostly employ a single motor drive or a simple mechanical energy storage structure, generally suffering from low power transmission efficiency, insufficient protection against reverse impacts, and poor coordination between energy storage and release. Traditional starter reduction mechanisms are mostly single-stage transmissions, which not only make it difficult to match the reduction ratio to different operating conditions but also lack an effective unidirectional limiting structure, making them susceptible to reverse force impacts from the flywheel after the gasoline engine starts, leading to internal gear wear, jamming, or even damage. Simultaneously, existing energy storage devices mostly use a direct spring drive, resulting in significant energy loss during storage and unstable power output during release, making efficient starting difficult. Furthermore, existing release devices mostly use mechanical locking structures, resulting in slow trigger response, uneven switching between locking and disengagement states, and a tendency for false triggering or incomplete unlocking, affecting starting reliability. In plug-in hybrid drive scenarios, the starter also needs to be adapted to the coordinated operation of the motor and energy storage mechanism. The existing structure is difficult to balance the stability of power transmission and the comprehensiveness of protection, and cannot meet the starting requirements of gasoline engines for high efficiency, reliability and long life. Therefore, there is an urgent need for a plug-in hybrid drive gasoline engine starter with efficient deceleration transmission, reliable one-way protection, stable energy storage release and coordinated protection functions to solve the above problems.

The left side of the transmission sleeve 51 is fixedly connected to the right side of the energy storage device 4, and the right side of the transmission sleeve 51 is movably connected to the inside of the annular cavity 54.

[0033] like Figure 8 As shown, the protective device 6 includes a connecting shaft 3 61, a clutch 1 62, a connecting shaft 4 63, a clutch 2 64, a connecting shaft 5 65, and a fixed housing 66. The fixed housing 66 is externally fixedly connected to the inside of the connecting sleeve 8, and the fixed housing 66 contains clutch 1 62 and clutch 2 64. The right side of clutch 1 62 is connected to the starting gear 7 via connecting shaft 3 61, and the left side of clutch 1 62 is connected to the right side of clutch 2 64 via connecting shaft 4 63. The left side of clutch 2 64 is connected to the center right side of the energy storage device 4 via connecting shaft 5 65.

[0034] Among them, clutch one 62 and clutch two 64 are an overrunning clutch and an electromagnetic clutch, respectively.

[0035] The invention is used in the following way: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, first, the motor 3 is started. The output shaft on the right side of the motor 3 transmits power to the input end of the reduction mechanism 22 of the one-way reduction device 2 (i.e., the center of the left side of input shaft 221), driving input shaft 221 to rotate synchronously. The small gear 222 outside input shaft 221 rotates with the shaft, driving the meshing large gear 223 to rotate. The small gear 224 on the center shaft to the right of large gear 223 rotates synchronously, driving the meshing large gear 228. The large gear 228 rotates; the transmission gear 227 on the right side of the central shaft drives the meshing transmission gear 225 to rotate, and then transmits the reduced power to the energy storage device 4 through the transmission shaft 226. During this process, the connecting gear 234 of the one-way mechanism 23 meshes with the small gear 224 and moves accordingly. The connecting shaft 233 forms a one-way transmission fit with the fixed housing 231 through the one-way bearing 232, ensuring that the power is transmitted only in the direction of "motor 3 → reduction mechanism 22" to avoid interference from reverse forces. The right side of the transmission shaft 226 drives the connecting shaft 225 of the energy storage device 4. 44 rotates, and the outer side of the connecting shaft 44 pulls the inner end of the energy storage coil spring 42 to rotate; since the outer end of the energy storage coil spring 42 is fixed to the inner wall of the rotating housing 41, and the rotating housing 41 is limited and movably connected to the center of the outer housing 1 by the fixed cover plate 43, the energy storage coil spring 42 gradually tightens and stores elastic potential energy until the preset energy storage threshold is reached, the motor 3 stops working, and the energy storage stage is completed. At this time, the release device 5 is in an untriggered state, and the movable ring 56 remains stationary in the initial state of the oil cylinder 55, and its outer conical surface 57 is perpendicular to the inner wall of the transmission sleeve 51. When the inner conical surface 53 is in a locked state, the release device 5 activates several hydraulic cylinders 55. The piston rod on the left side of the hydraulic cylinder 55 pushes the movable ring 56 to move laterally to the right within the annular cavity 54 of the annular housing 52. The outer conical surface 57 of the movable ring 56 gradually separates from the inner conical surface 53 of the inner wall of the transmission sleeve 51, so that the transmission sleeve 51 and the annular housing 52 are separated. Then the elastic potential energy of the energy storage coil spring 42 of the energy storage device 4 is released, which drives the rotating housing 41 to rotate. The right side of the rotating housing 41 transmits power through the connecting shaft 55 of the protective device 6.At this time, clutch 64 (electromagnetic clutch) of protective device 6 is energized and engaged. Power is transmitted sequentially through connecting shaft 65 → clutch 64 → connecting shaft 63 → clutch 62 (overrunning clutch) → connecting shaft 61 to starter gear 7, driving starter gear 7 to rotate at high speed. Starter gear 7 meshes with the flywheel ring gear of the gasoline engine, transmitting power to the crankshaft of the gasoline engine, driving the crankshaft to rotate and completing the ignition and starting of the gasoline engine. During this process, clutch 62 (overrunning clutch) of protective device 6 plays a one-way protection role, preventing the high-speed reverse power of the flywheel after the gasoline engine starts from being transmitted to the internal components of the starter. After the gasoline engine starts successfully, its flywheel speed is higher than the speed of starter gear 7, and clutch 62 (overrunning clutch) automatically disengages, cutting off the reverse power transmission from "gasoline engine → starter", preventing damage to the internal gears of the starter due to high-speed reverse impact. At the same time, clutch 64 (electromagnetic clutch) is de-energized and disengaged, interrupting energy storage. Device 4 is connected to the starting gear 7. Then, the piston rod of the hydraulic cylinder 55 extends to drive the outer conical surface 57 to be locked with the inner conical surface 53 of the inner wall of the transmission sleeve 51. If restarting is required, the motor 3 restarts and repeats the energy storage stage process, and the energy storage coil spring 42 tightens again to store energy. If restarting is not required, the energy storage device 4 remains stationary, waiting for the next trigger. When power overload or jamming occurs during the starting process, the clutches 62 and 64 of the protection device 6 work together: clutch 62 avoids hard impact through its overrunning characteristic, and clutch 64 can quickly cut off power transmission by disconnecting the power. At the same time, the one-way bearing 232 of the one-way reduction device 2 prevents the gear set (small gear 222, large gear 223, etc.) of the reduction mechanism 22 from being damaged by reverse force. The outer shell 1 and the fixed housings of each component (such as fixed housing 231 and fixed housing 66) provide overall protection to prevent internal components from falling out or being damaged by external impact.
