Definitions

  • a dual-clutch transmission system for a vehicle comprises a first input shaft configured with a first set of input gears connectable to a crankshaft of an engine through a first clutch member.
  • a second input shaft configured with a second set of input gears is mounted concentrically to the first input shaft and connectable to the crankshaft of the engine through a second clutch member.
  • a first layshaft and a second lay shaft are mounted parallel to the first input shaft and are configured with a first set of driven gears and a second set of driven gears. Each of the first set of driven gears and the second set of driven gears are meshed to the corresponding first set of input gears and the corresponding second set of input gears.
  • the second input shaft (9) is mounted concentrically to the first input shaft (8) and is connectable to the crankshaft of the engine through a second clutch member (13).
  • the second input shaft (9) includes a second set of input gears (104), wherein the second set of input gears (104) are configured with predetermined gear tip diameters and are arranged in a predetermined sequence for transmitting torque at different gear ratios, based on the power demand.
  • the first set of input gears (103) may include odd numbered gears i.e. first gear (1), third gear (3), fifth gear (5) and seventh gear (7).
  • the second set of input gears (104) may include even numbered gears i.e. second gear (2), fourth gear (4) and sixth gear (6).
  • the first set of input gears (103) may include even numbered gears and the second set of input gears (104) may include odd numbered gears.
  • a first layshaft (10) is mounted parallel to the first input shaft (8) and includes a first set of driven gears (105), positioned sequentially along the first layshaft (10).
  • the first set of driven gears (105) which are positioned such that, each driven gear of the first set of driven gears (105) are in mesh with the corresponding input gear of the first and the second set of input gears (103 and 104).
  • the meshing of the first set of driven gears (105) with the corresponding first and the second input gears (103 and 104) provides the corresponding gear ratio, based on which the torque received from the engine is transmitted to the wheels.

Abstract

La présente invention porte sur un système de transmission à double embrayage destiné à un véhicule. Le système comprend un premier arbre d'entrée (8) agencé avec un premier ensemble de pignons d'entrée (103) pouvant être relié à un vilebrequin d'un moteur. Un second arbre d'entrée (9), agencé avec un second ensemble de pignons d'entrée (104), est monté de manière concentrique sur le premier arbre d'entrée et peut être relié au vilebrequin du moteur. Un premier arbre intermédiaire (10) et un second arbre intermédiaire (11) sont montés parallèlement au premier arbre d'entrée et sont agencés avec des pignons menés (105, 106). Chacun des pignons menés est en prise avec les pignons d'entrée correspondants. Un arbre intermédiaire (19) est monté parallèlement au second arbre intermédiaire et comprend un premier pignon intermédiaire (17) et un second pignon intermédiaire (19). Le premier pignon intermédiaire (17) est en prise avec l'un des pignons d'entrée du second ensemble de pignons d'entrée (104). Cette configuration offre au système un montage compact, éliminant ainsi les contraintes de conditionnement.
