Abstract
A first electric motor cooling flow passage (120A) and a first electric motor lubrication flow passage (121A) supply oil from an electric oil pump (70) through the outer side of one end (E1) of the first electric motor (2A) to the portions (A1, A2) of the first electric motor (2A) which are to be cooled/lubricated. A second electric motor cooling flow passage (120B) and a second electric motor lubrication flow passage (121B) supply oil from the electric oil pump (70) through the outer side of the other end (E2) of the second electric motor (2B) to the portions (B1, B2) of the second electric motor (2B) which are to be cooled/lubricated.
Claims22
A vehicle driving device comprising:
- an electric motor connected to a wheel of a wheel;
- a liquid medium supply device configured to supply a liquid medium to a portion to be cooled/lubricated, which is at least one of a portion of the electric motor to be cooled and a portion of the electric motor to be lubricated;
- and
- a case which accommodates the electric motor and comprises:
- a reservoir for reserving the liquid medium;
- a cooling/lubrication flow passage through which the liquid medium supply device and the portion of the electric motor to be cooled/lubricated are communicated with each other,
- wherein the liquid medium supply device discharges the liquid medium sucked from the reservoir and supplies, via the cooling/lubrication flow passage, the liquid medium to the portion of the electric motor to be cooled/lubricated,
- wherein the vehicle driving device further comprises:
- a separate member which is detachably provided to the case and on which the liquid medium supply device is provided,
- wherein the case comprises an opening which is opened outward, and
- wherein in an attached state where a separate member fixation portion of the case and a case fixation portion of the separate member are fixed to each other, the opening of the case is closed by the separate member, and a discharge-side flow passage of the liquid medium supply device, which is provided on the separate member, and the cooling/lubrication flow passage of the case are connected to each other.
