DOUBLE CLUTCH TRANSMISSION Russian patent published in 2022 - IPC F16D25/10 F16D21/06 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, and more specifically to vehicle transmission clutches. The transmission double clutch contains friction clutches 2 and 3 of the same size with packages 4, 5 of leading 6, 7 and driven 8, 9 friction discs, pistons 10 and 11 installed in housings 12, 13 on hubs 14, 15 and hydraulic cylinders 26 and 27. The hubs 14 and 15 are connected to the rims 16 and 17, which have protrusions 18 and 19. The protrusions of the leading 6, 7 and pressure disks 31 and 32 are engaged with the protrusions 18 and 19. Wave springs 33 are installed between the leading 6, 7 and pressure disks 31 and 32 Driven disks 8 and 9 are engaged with protrusions 34 and 35 of drums 36 and 37. Drums 36 and 37 have splined bushings 38 and 39. Clutches 2 and 3 are separated by a bearing 42 installed between the ends of the bushings 38 and 39, are mirrored and interconnected cylindrical sleeve 43. The sleeve 43 is made with protrusions 44 engaged with the outer protrusions 45 and 46 of the profile rims 16 and 17, and end slots 47 and 48 on its two sides. Grooves 47 and 48 intersect annular grooves 49. Grooves 47 and 48 are located above the end grooves 50 and 51 made in the rims 16 and 17. The end grooves 50 and 51 intersect the annular grooves 52. The grooves 50, 51, 47 and 48 are protrusions 53 and 54 thrust disks 29 and 30, and in the annular grooves 49, 52 - retaining rings 55, 56. The pistons 10, 11 of the couplings 2, 3 are mounted on the hub 14, 15 connected to the drive shaft 28. The hubs 14 and 15 are equipped with bearings 58 and 59. In the hubs 14 and 15, radial holes 60 and 61 are made, communicating with the working chambers 24 and 25 of the hydraulic cylinders 26 and 27, and inclined holes 62 and 63, communicating with the compensation chambers 20, 21.

EFFECT: simplification of the design with ensuring reliability, manufacturability and maintainability is achieved.
