Description

Technical Field

[0001] The utility model relates to the technical field of all-in-one starting machines, in particular to a disc-type all-in-one starting motor for an automobile. Background Art

[0002] The automotive helical integrated machine is located at the front end of the engine and is connected to the engine through a belt drive. This product belongs to weak hybrid technology, which is a hybrid technology with idling stop and start functions. It can stop the engine at red lights and in traffic jams. When the vehicle recognizes that the driver intends to start, the system quickly starts the engine through the automotive helical integrated machine system, thus eliminating the fuel consumption, emissions and noise of the engine when idling, reducing environmental pollution and energy consumption.

[0003] At present, when using an integrated initiator for automobiles, most of them directly use a motor to directly drive a belt to start the engine. When the vehicle is idling and starting, it is only driven by electricity. When the vehicle speed exceeds a certain speed, the gasoline engine starts to work. Since the torque of the integrated initiator for automobiles is fixed, electric drive cannot be achieved when the air-conditioning system of the vehicle is turned on. Therefore, an integrated initiator for automobiles is proposed. Utility Model Content

The inner wall of the sliding ring 701 is provided with a convex block, which corresponds to the connecting groove 103 one by one and can be slidably arranged in the corresponding connecting groove 103, so that the sliding ring 701 can not only slide along the axial direction of the rotating shaft 101, but also rotate with the rotating shaft 101. A connecting block 804 is slidably installed in each through slot 104, and the connecting block 804 is fixedly connected to the corresponding protrusion, and the connecting block 804 can slide relative to the sliding column 803, and can rotate relative to the sliding column 803.

[0035] Specifically, an arc groove is arranged around the middle of the sliding column 803, and a slider is arranged on the inner side of each connecting block 804. The slider is slidably arranged in the arc groove, so that the connecting block 804 can rotate relative to the sliding column 803, and slide synchronously with the sliding column 803 along the axial direction of the rotating shaft 101.

[0036] The first transmission assembly 4 includes a first fixed frame 401, a first sun gear 402, a fixed pipe 403, a first connecting disc 405 and a first planetary gear 406. The first connecting disc 405 is fixedly mounted on the fixed plate 202, and the first sun gear 402 is fixedly mounted in the middle of the first fixed disc 405, that is, the first sun gear 402 is fixedly arranged. The first fixed frame 401 is arranged on a side of the first sun gear 402 away from the first fixed disc 405, and the fixed pipe 403 is fixedly mounted on the first fixed frame 401. One end of the fixed pipe 403 is fixedly connected to the first fixed frame 401 and keeps synchronous rotation, and the other end of the fixed pipe 403 can be rotatably extended into the first sun gear 402, so that the first fixed frame 401 and the first sun gear 402 can rotate relative to each other. The first fixed frame 401 is the planetary frame of the first transmission assembly 4. The first planetary gears 406 are rotatably mounted on the first fixing frame 401. At least three first planetary gears 406 are evenly spaced around the first sun gear 402, and all the first planetary gears 406 are meshed with the first sun gear 402. The first planetary gears 406 are located inside the gear ring 203 and meshed with the gear ring 203. The gear ring 203 is the outer gear ring of the first transmission assembly 4.

[0037] A first limiting groove 404 cooperating with the second limiting block 703 is provided on the end face of the fixed tube 403 close to the sliding ring 701. When the sliding ring 701 slides toward the fixed tube 403 and the second limiting block 703 engages with the first limiting groove 404, the first fixed frame 401 keeps synchronous rotation with the sliding ring 701, and then keeps synchronous rotation with the rotating shaft 101.

[0038] The second transmission assembly 5 includes a second fixed frame 501, a second fixed disk 502, a second sun gear 503, a connecting pipe 505, a second limiting gear ring 506 and a second planetary gear 507. The connecting pipe 505 is fixedly connected to the second fixed disk 502, and the second fixed disk 502 and the fixed column 204 can rotate relative to each other. The second sun gear 502 and the second planetary gear 507 are both arranged between the second fixed disk 502 and the fixed column 204, and the second sun gear 503 is rotatably connected to the fixed pipe 505. The second planetary gear 507 is rotatably installed on the second fixed frame 501. At least three second planetary gears 507 are arranged around the second sun gear 503 at intervals, and each second planetary gear 507 is meshed with the second sun gear 503. A second limiting groove 504 that matches with the first limiting block 701 is provided on the end surface of the second sun gear 503 near the sliding ring 701. When the first limiting block 701 matches with the second limiting groove 504, the second sun gear 503 and the rotating shaft 101 remain relatively fixed. A second limiting gear ring 506 is fixedly mounted on the fixing tube 505. The limiting gear 606 on the connecting rod 601 near the fixing tube 505 can penetrate into the second limiting gear ring 506 and mesh with the second limiting gear ring 506.

[0039] The second planetary gear 507 is located inside the gear ring 203 and meshes with the gear ring 203, which also serves as the outer gear ring of the second transmission assembly 5. Both ends of the second planetary gear 507 are rotatably connected to the second fixed plate 502 and the second fixed frame 501, respectively, so that the second fixed plate 502 and the second fixed frame 501 are combined into a planetary carrier of the second transmission assembly 5.

[0040] When the engine needs to be started, the connecting rod 601 is first controlled to move by the electric push rod, so that the limiting gear 602 at the bottom is connected to the second limiting gear ring 506, and at the same time, the electromagnetic clutch limits the fixed column 204 and the gear ring 203 to prevent the gear ring 203 from rotating during use. At this time, the sliding ring 701 moves synchronously and makes the first limiting block 702 mesh with the second limiting groove 504, so that the second sun gear 503 is connected to the rotating shaft 101 through the cooperation of the second limiting groove 504 and the first limiting block 702. The rotating shaft 101 rotates under the drive of the integrated motor body 1, and the rotating shaft 1 01The second sun gear 503 is driven to rotate under the connection of the sliding ring 701 and the first limit block 702. Since the gear ring 203 is fixed relative to the fixed shell 2, the second sun gear 503 is engaged with the second planetary gear 507 and drives the second fixed frame 501 and the second fixed disk 502 to rotate. The rotating second fixed disk 502 drives the connecting rod 601, the sliding column 803 and the connecting shaft 801 to rotate through the cooperation of the connecting tube 505, the second limit gear ring 506 and the limit gear 602, and then the connecting shaft 801 starts the engine through the pulley 805 and the belt to ensure stability when starting the engine.

[0041] When the engine is started, the electromagnetic clutch is used to release the limit on the fixed column 204. At the same time, the electric push rod pushes the connecting rod 601 to move, so that the limit gear 602 at the top of the connecting rod 601 is connected to the first limit gear ring 206, so that the limit gear 602 at the bottom of the connecting rod 601 is separated from the second limit gear ring 506. During the movement of the connecting rod 601, the sliding ring 701 is pushed to move by the sliding column 803 and the connecting block 804, so that the first limit block 702 at one end of the sliding ring 701 is separated from the second limit groove 504, and the second limit block 703 is pushed into the first limit groove 404, so that the rotating shaft 101 is connected to the first fixed frame 401. Then the belt passes through The pulley 805 drives the connecting shaft 801, the sliding column 803 and the connecting rod 601 to rotate. Since the limiting gear 602 is fixed to the connecting rod 601, when the connecting rod 601 rotates, the fixing column 204 and the gear ring 203 are driven to rotate through the limiting gear 602. When the gear ring 203 rotates, the first fixing frame 401 is driven to rotate through the engagement with the first planetary gear 406. Since the first fixing frame 401 is connected to the rotating shaft 101 through the sliding ring 701 and the second limiting block 703, the rotating first fixing frame 401 drives the rotating shaft 101 and the integrated motor body 1 to generate electricity, thereby avoiding the unstable power generation caused by the heavy load of the integrated motor body 1 when the engine is at a low speed.
