Electronic rear drive module with split halfshaft flange

摘要

The present teachings provide for a vehicle drive module including a housing, an electric motor, a transmission gear set, a differential assembly, and a pair of output members. The transmission gear set can transmit rotary power between a motor output shaft and an output of the transmission gear set. The differential assembly can include a case, a pair of pinion gears, and a pair of side gears. Each of the side gears can be meshingly engaged with the pair of pinion gears. Each output member can include a driven body and an outer flange. The driven body can have a first end drivingly coupled to one of the side gears. The outer flange can have a first side that is releasably coupled to the second end of the driven body, and a second side that is adapted to be releasably coupled to a constant velocity joint.

1. A vehicle drive module comprising:
a housing; an electric motor coupled to the housing and having a motor output shaft; a transmission gear set received in the housing and coupled to the motor output shaft for transmission of rotary power between the motor output shaft and an output of the transmission gear set; a differential assembly including:
a case supported within the housing for rotation about a first axis and drivingly coupled to the output of the transmission gear set;a pair of pinion gears received in the case and rotatable relative to the case about a second axis that is perpendicular to the first axis; anda pair of side gears received in the case and rotatable about the first axis, each of the side gears being meshingly engaged with the pair of pinion gears; and a pair of output members, each output member including:
a driven body having a first end and a second end, the first end is drivingly coupled to a respective one of the side gears to receive rotary power therefrom, and the second end defines a circumferential lip; andan outer flange having an inner surface that defines a first inner cavity, the first inner cavity being adapted to receive a first portion of a constant velocity joint, and wherein the inner surface is releasably mounted about the circumferential lip; wherein the driven body has an outboard surface that is radially outward of the circumferential lip and configured to abut an inboard surface of the outer flange; wherein the driven body defines a plurality of first bores spaced circumferentially about the outboard surface of the driven body, and the outer flange defines a plurality of second bores, each of the second bores aligning with a respective one of the first bores; and wherein the first and second bores are adapted to receive a corresponding fastener therein to releasably couple the driven body and the outer flange for common rotation.
