Dual clutch transmission

A dual clutch transmission comprising:

• an input shaft;
• an output shaft;
• an odd-numbered speed gear train group including at least one odd-numbered speed gear train for transmitting power from the input shaft to the output shaft;
• an even-numbered speed gear train group including at least one even-numbered speed gear train for transmitting power from the input shaft to the output shaft;
• a first clutch for selectively making or interrupting power transmission from the input shaft to the output shaft via any one odd-numbered speed gear train selected from the odd-numbered speed gear train group;
• a second clutch for selectively making or interrupting power transmission from the input shaft to the output shaft via any one even-numbered speed gear train selected from the even-numbered speed gear train group;
• a housing including first and second end portions mutually opposite in an axial direction of the input shaft, the housing being formed therein with a gear chamber close to the first end portion of the housing, and with a clutch chamber close to the second end portion of the housing,
• wherein the input shaft, the output shaft, the odd-numbered speed gear train group, and the even-numbered speed gear train group are disposed in the gear chamber,
• wherein the first clutch and the second clutch are disposed in the clutch chamber,
• wherein a first end portion of the input shaft projects outward from the first end portion of the housing so as to be connected to a prime mover, and a second end portion of the input shaft is extended into the clutch chamber so as to be connected to the first and second clutches, and
• wherein the clutch chamber has an opening at the second end portion of the housing;
• and
• a cover detachably attached to the second end portion of the housing so as to close the opening of the clutch chamber.
