Abstract:
An automotive motor drive unit includes a breather passage (Q) provided in casings (21a, 21r, 22a, 22r) that form an outer shape of the automotive motor drive unit; an entrance port (48m) that is provided at an inlet side of the breather passage and that connects with an internal space (L) defined by the casings; an exit port (67) that is provided at an outlet side of the breather passage and that connects with a space outside the casings; and obstacles (24, 25, 26) standing to form an inner wall of the breather passage and preventing lubrication oil in the internal space from proceeding straight ahead via the entrance port toward the exit port.
Abstract:
A terminal mounting structure includes a plurality of receive-side terminals, each of which extends from a distal end of each of electrical leads, a mounting stand that includes an electrically-insulating base and a plurality of supply-side conductive bars that are disposed at intervals and extend so as to pass through the base, a plurality of screws, each of which passes through the receive-side terminal in a direction crossing an extending direction of the receive-side terminal, each of which is screwed into a screw hole formed at an end part of the supply-side conductive bar so as to cause each of the receive-side terminals to contact each of the supply-side conductive bars and to fix each of the receive-side terminals to each of the supply-side conductive bars, and a contact prevention mechanism that is provided in the mounting stand so as to prevent adjacent receive-side terminals from contacting with each other.

Abstract:
An in-wheel motor drive unit (11) includes: a motor portion (11A) that is placed on one side in the direction of the axis of the in-wheel motor drive unit; a wheel hub portion (11C) that is placed on the other side in the direction of the axis of the in-wheel motor drive unit; a speed reduction portion (11B) that is placed between the motor portion and the wheel hub portion and that reduces the speed of output rotation of the motor portion to transmit the resultant output rotation to the wheel hub portion; and a first arm portion (34) that is formed integrally with a speed reduction portion casing (33) forming the outer shape of the speed reduction portion, that projects in a direction perpendicular to the axis from the speed reduction portion casing, and that has its tip end pivotally coupled to a vehicle body-side member.

Abstract:
A motor drive assembly for a vehicle is provided and includes an electric motor. A rotor of the electric motor includes a spindle rotatably supported by a first bearing located on a first side of the spindle close to a speed reducer and a second bearing located on a second side of the spindle opposite from the first side of the spindle and remote from the speed reducer. The spindle includes a tubular, hollow, rotor core mounting portion having an inner diameter larger than the diameter of a cylindrical surface on which the first bearing is fitted.
Abstract:
A suspension structure includes a pair of trailing arms (12), a beam member (13) connecting the pair of trailing arms, a bracket (21) connected to a rear end region of the trailing arm, and an in-wheel motor drive device (31) coupled and fixed to the bracket. The in-wheel motor drive device (31) is located above the rear end region of the trailing arm (12), and a lower side of the in-wheel motor drive device (12) is covered by the rear end region of the trailing arm (12) and the bracket (21).
Abstract:
In the link structure linking an in-wheel motor drive device (11) placed in a hollow area of a road wheel (W) of a turnable wheel to a damper (31), a damper bracket (32) extends in the vehicle traverse direction and at least a transversely outer end (321) of the damper (31) is placed in the hollow area of the road wheel (W). A first joint (18) is placed in the hollow area of the road wheel, and rotatably links the transversely outer end (321) of the damper bracket (32) to the in-wheel motor drive device (11). The damper (31) has a lower end (311) coupled to a transversely inner end (322) of the damper bracket (32).
