Abstract
A portal unit of the present invention includes a deceleration gear train and a housing. The housing includes an inner side wall that is formed with an input opening at a position above a rotation axial line of a driving wheel, an outer side wall that is formed with an output opening at a coaxial position with the rotation axial line of the driving wheel, and an intermediate wall that connects peripheral edges of the inner side wall and the outer side wall. The inner side wall is provided, at a radially outward position of the input opening, with mount bolts for the suspension unit. The mount bolts each include a shaft portion protruding inwardly in a vehicle width direction.
Claims9
A portal unit interposed between a suspension unit and a driving wheel in a vehicle, the portal unit comprising:
- a deceleration gear train decelerating a rotational power that is operatively transmitted from a drive source provided in the vehicle;
- and
- a housing accommodating the deceleration gear unit,
- wherein the housing includes an inner side wall that is formed, at a position above a rotation axial line of the driving wheel, with an input opening for inputting the rotational power operatively transmitted from the drive source into the deceleration gear train, an outer side wall that is formed, at a coaxial position with the rotation axial line of the driving wheel, with an output opening for outputting the rotational power, which is decelerated by the deceleration gear train, toward the driving wheel, and an intermediate wall that connects peripheral edges of the inner side wall and the outer side wall so as to form an accommodating space for accommodating the deceleration gear train,
- wherein the inner side wall is provided, at a radially outward position of the input opening, with mount bolts for the suspension unit, and
- wherein the mount bolts each include a shaft portion protruding inwardly in a vehicle width direction.
