Description

Technical Field

[0001] This utility model relates to the field of clutch gearbox technology, specifically a clutch gearbox mechanism. Background Technology

[0002] A clutch is a device installed between the drive shaft and the driven shaft, located in the flywheel housing between the engine and the gearbox, used to separate or engage the rotational motion of the two shafts. Clutches are primarily in the form of gearboxes. However, current gearbox mechanisms for clutches use push-pull gears for frictional meshing to switch power speeds, resulting in high wear, reduced transmission meshing accuracy, and increased jerking. Therefore, this paper proposes a new clutch gearbox mechanism to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide a clutch gearbox mechanism to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a clutch gearbox mechanism, including a gearbox body, a cylinder brake part, a double-layer sub-gear, an upper master gear, a lower master gear, and a power input shaft. The upper master gear and the lower master gear are respectively arranged at the middle position inside the gearbox body, and the upper master gear and the lower master gear are connected by a double-layer sub-gear transmission. An unlocking and locking part is provided between the upper master gear and the lower master gear, and the unlocking and locking part is connected to the power input shaft. An output gear plate mounting part is fixedly connected to the middle of the outer side of the upper master gear, and a through hole is opened in the middle of the output gear plate mounting part.

[0005] In a further technical solution, the double-layer sub-gear is in a start-stop control state through a cylinder brake part located inside the gearbox, and the power execution cylinder located in the cylinder brake part is installed outside the gearbox.

[0006] In a further technical solution, one side of the middle part of the power input shaft is rotatably connected to the bottom of the gearbox via a bearing, and one end of the power input shaft is connected to an external electric drive device.

[0007] A further technical solution is that the unlocking and locking part includes a linear bearing and a locking block. The linear bearing is installed at the other end of the power input shaft, and the top of the linear bearing is connected to the cylinder output end installed at the through hole. The locking block is installed on the side wall of the top of the linear bearing.

[0008] In a further technical solution, the locking block switches between slot 2 and slot 1 by moving up and down. Slot 1 is located on the upper female gear, and slot 2 is located on the lower female gear.

[0009] As stated above.

[0010] Compared with the prior art, the advantages of this utility model are as follows: a double-layer sub-gear is connected between the upper master gear and the lower wooden gear with two transmission ratios. At the same time, a lock block that can be driven to rotate can be switched between slot one and slot two to realize the function of adjusting the transmission speed ratio. Moreover, the speed switching is completed without the need for frictional meshing between gears. Furthermore, the difference in speed between the front and back switching is large, which can form a distinct power difference impact effect during high-frequency switching. This can meet the power switching requirements of mixing, conveying end connection, etc. Attached Figure Description

[0017] Please see Figure 1-4 As shown, a clutch gearbox mechanism includes a gearbox body 1, a cylinder brake part 3, a double-layer sub-gear 4, an upper master gear 5, a lower master gear 6, and a power input shaft 8. The upper master gear 5 and the lower master gear 6 are respectively arranged at the middle position inside the gearbox body 1, and the upper master gear 5 and the lower master gear 6 are connected by the double-layer sub-gear 4. An unlocking and locking part is provided between the upper master gear 5 and the lower master gear 6, and the unlocking and locking part is connected to the power input shaft 8. An output gear plate mounting part 2 is fixedly connected to the middle of the outer side of the upper master gear 5, and a through hole 210 is opened in the middle of the output gear plate mounting part 2. The unlocking and locking part includes a linear bearing 7 and a locking block 710. The linear bearing 7 is installed at the other end of the power input shaft 8, and the top of the linear bearing 7 is connected to the cylinder output end installed at the through hole 210. The locking block 710 is installed on the side wall of the top of the linear bearing 7. The locking block 710 switches between slot 2 610 and slot 1 510 by moving up and down. Slot 1 510 is opened on the upper female gear 5, and slot 2 610 is opened on the lower female gear 6.

[0018] The double-layer sub-gear 4 is in a start-stop control state through the cylinder brake part 3 located inside the gearbox 1, and the power execution cylinder 310 located in the cylinder brake part 3 is installed outside the gearbox 1.

[0019] The middle side of the power input shaft 8 is rotatably connected to the bottom of the gearbox 1 via a bearing, and one end of the power input shaft 8 is connected to an external electric drive device.

[0020] Working principle: The rotation of the power input shaft 8 can cause the locking block 710 connected by the linear bearing 7 to move together. When the locking block 710 is pushed down and inserted into the slot 610 on the lower master gear 6, the lower master gear 6 rotates. At the same time, the lower master gear 6 rotates through the driven upper master gear 5 connected by the double-layer sub-gears 4 with different transmission ratios, which further drives the output gear plate mounting part 2 and the external gear plate connected to the upper master gear 5 to rotate. When the locking block 710 is pulled up and inserted into the slot 510 on the upper female gear 5, the upper female gear 5 is rotated as the driving gear, and the lower female gear 6 is in the driven state, thereby realizing the function of adjusting the transmission speed ratio. Among them, the cylinder brake section 3 has the effect of instantly stopping the rotation of the double-layer sub-gear 4.

[0021] Compared with existing technologies, the difference lies in the use of a double-layered sub-gear 4 connected between the upper master gear 5 and the lower wooden gear 6 with two transmission ratios. At the same time, a lock block 710 that can be driven to rotate can be switched between slot one 510 and slot two 610 to achieve the function of adjusting the transmission speed ratio. Moreover, the speed switching is completed without the need for frictional meshing between gears. Furthermore, the difference in speed between the front and back switching is large, which can form a distinct power difference impact effect during high-frequency switching, and can meet the power switching requirements of mixing, conveying end connection, etc.
