Definitions

  • the present invention relates to a double clutch system applicable to vehicles in which the primary axle is parallel to the motor axle, such as, for example, in motorcycles.
  • Dual clutch systems can be defined as two partial manual gearboxes whose clutches work in parallel and are mechanically actuated.
  • a gearbox has two gear shafts. The axis through which the engine power enters and the axis through which the power leaves the drive wheels.
  • a dual-clutch system has two coaxial primary gear shafts through which power arrives and a secondary shaft.
  • One of the primary axes has the odd relations (first, third and fifth) and the other the even ones (second, fourth and sixth), and each axis has its own clutch. That is, there are two clutches instead of one. Every time a gear is engaged, the following relationship is also involved, so that when moving to a higher gear it is not necessary to carry out the entire disengagement and engagement process, but only to disengage one clutch and engage the other at the same time. .
  • Dual-clutch systems were introduced years ago in automotive engines, where the primary shaft is usually aligned with the drive shaft.
  • the double clutch is a complex unit of coaxial shafts so that the two clutches act on two coaxial primary shafts.
  • the first applications that have been made of double clutch in motorcycles its philosophy is the same as in the automotive industry, but applied on the primary axle as usual in motorcycles.
  • the double clutch systems for motorcycles applied on the primary shaft have the same configuration as those applied in the automotive sector and maintain their complexity of coaxial shafts to allow the two clutches to act.
  • the objective of the double clutch according to the present invention is to solve that complexity for its application in typical motorcycle engines, that is, with the primary axis and the motor axis parallel to each other.
  • the dual clutch system comprises a primary shaft, a first clutch assembly and a second clutch assembly, wherein said first clutch assembly is disposed at one end of the primary shaft and said second clutch assembly it is arranged at the other end of the primary shaft.
  • the first clutch assembly and the second clutch assembly are equal to each other.
  • the dual-clutch system according to the present invention also comprises a first transmission assembly integral with rotation with the first assembly of clutch and a second transmission assembly integral with rotation with the second assembly of clutch.
  • the first transmission set has a different relationship than the second transmission set, although the first transmission set and the second transmission set may be the same with each other.
  • the primary shaft comprises a six-speed gear box, with three duplicate gear sets.
  • the primary shaft comprises a six-speed gearbox, with six gear sets.
  • the primary shaft comprises a six-speed gear box, with three sets of gears.
  • Fig. 1 is a sectional view of the dual clutch system according to a first embodiment of the present invention
  • Figure 2 is a sectional view of the dual clutch system according to a second embodiment of the present invention.
  • Fig. 3 is a sectional view of the double clutch system according to a third embodiment of the present invention.
  • This double clutch system comprises a primary shaft 1, a first clutch assembly 2 and a second clutch assembly 3, the first clutch assembly 2 being arranged at one end of the primary shaft 1 and said second clutch assembly 3 being arranged in the other end of the primary shaft 1, as seen in figure 1. Furthermore, the first clutch assembly 2 and the second clutch assembly 3 are equal to each other.
  • the double clutch system according to the present invention also comprises a first transmission assembly 4 integral in rotation with the first clutch assembly 2 and a second transmission assembly 5 integral in rotation with the second clutch assembly 3.
  • the first transmission set 4 has a different relationship than the second transmission set 5, and the primary shaft 1 comprises a six-speed gear box 6, which is formed by three gear sets 7, 8, 9 duplicates.
  • This configuration allows to have two gears coupled at the same time to have a faster selection of speeds.
  • a second embodiment of the double gear system according to the present invention is shown in Figure 2.
  • the same reference numbers are used to identify the same elements, and only the differences from the first embodiment will be described.
  • One of the differences between this second embodiment and the first embodiment is that the first transmission set 4 is the same as the second transmission set 5, with the same relationship.
  • the six-speed gearbox 6 comprises six gear sets 10, 11, 12, 13, 14, 15 that are different from each other.
  • This option is best for a competition engine.
  • FIG. 3 A third embodiment of the double gear system according to the present invention is shown in Figure 3.
  • the same reference numbers are used to identify the same elements, and only the differences from the first embodiment will be described.
  • the six-speed gearbox 6 comprises three sets of gears 16, 17, 18.
  • This embodiment is the cheapest and also the one with the least weight, because using fewer components you can also achieve six speeds, achieving a compact engine.

Abstract

Selon l'invention, le système d'embrayage double comprend un axe primaire (1), un premier ensemble d'embrayage (2) et un second ensembe d'embayage (3), ledit premier ensemble d'embrayage (2) étant placé à une extrémité de l'axe primaire (1) et ledit second ensembe d'embrayage (3) étant disposé à l'autre extrémité de l'axe primaire. Ce système permet d'utiliser des embrayages sans axes co-axiaux, d'avoir deux relations distinctes dans les transmissions primaires, et de dupliquer les mêmes engrenages dans le changement de rapport et de simplifier ainsi la production du changement de rapport.
