Abstract
A dual clutch transmission for a vehicle is provided. The transmission includes a first input shaft driven by a first clutch and a second input shaft driven by a second clutch. An output shaft or shafts are driven by the input shafts having selective mesh torsional force transferring gear contact therewith. A differential input gear is driven by the output shaft or shafts. At least one of the input shafts has at least one input gear that torsionally engages with the output shaft via an idler shaft having an idler input shaft torsionally connected on the idler shaft with an idler shaft output gear through a one-way clutch and wherein the idler shaft output gear is meshed with another gear on the one input shaft.
Claims15
A dual clutch transmission for a vehicle comprising:
- a first input shaft driven by a first clutch;
- a second input shaft driven by a second clutch;
- output shaft(s) driven by said input shafts having selective meshed torsional force transferring gear contact therewith;
- a differential input gear driven by said output shaft(s);
- and
- wherein at least one of said input shafts has at least one input gear that torsionally engages with said output shaft via an idler shaft having an idler shaft input gear torsionally connected on said idler shaft with an idler shaft output gear through a one way clutch and wherein said idler shaft output gear is meshed with another gear on said one input shaft.
A dual clutch transmission for a vehicle comprising:
- a first input shaft driven by a first clutch, said first input shaft having even gear ratio input gears mounted thereon;
- a second input shaft driven by a second clutch said second input shaft having odd gear ratio input gears located thereon;
- an output shaft driven by said input shafts having selective meshed torsional force transferring gear contact therewith;
- a differential input gear driven by said output shaft;
- and
- wherein at least one of said input shafts has at least one input gear that torsionally engages with said output shaft via an idler shaft having an idler shaft input gear torsionally connected on said idler shaft with an idler shaft output gear through a one way clutch and wherein said idler shaft output gear is meshed with another gear on said one input shaft.
A dual clutch transmission for a vehicle comprising:
- a first input shaft driven by a first clutch said first input shaft having second, fourth, sixth and reverse gear input gears mounted thereon;
- a reverse idler shaft with input and output gears torsionally connected to one another;
- a second input shaft driven by a second clutch, said second input shaft having first, third and fifth input gears located thereon;
- an output shaft driven by said input shafts having selective meshed torsional force transferring gear contact therewith;
- a differential input gear driven by said output shaft;
- and
- wherein said first input shaft has said first input gear that torsionally engages with an output gear on said output shaft via an idler shaft having an idler shaft input gear torsionally connected on said idler shaft with an idler shaft output gear through a one way clutch and wherein said idler shaft output gear is meshed with said third gear on said one input shaft.
