Abstract
Official abstract text for this publication.
A vehicle drive apparatus having a drive unit where the drive unit includes a motor that generates a driving force in a vehicle with a ladder frame, a transmission that changes the driving force transmitted from the motor, and a differential that splits the driving force transmitted from the transmission and transmits forces split to driving wheels of the vehicle. The vehicle drive apparatus includes a drive unit housing that houses at least part of the drive unit, a motor-side support coupling the drive unit housing to the ladder frame by two couplers arranged in a motor-side end region of the drive unit housing, and a differential-side support coupling the drive unit housing to the ladder frame in a differential-side end region of the drive unit housing. The two couplers of the motor-side support are arranged father outside in a vehicle width direction than the differential-side support.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle drive apparatus having a drive unit, wherein the drive unit includes: a motor that generates a driving force in a vehicle with a ladder frame; a transmission that changes the driving force transmitted from the motor; and a differential that splits the driving force transmitted from the transmission and transmits forces split to driving wheels of the vehicle, the vehicle drive apparatus comprising: a drive unit housing that houses at least part of the drive unit; a motor-side support coupling the drive unit housing to the ladder frame by two couplers arranged in a motor-side end region of the drive unit housing; and a differential-side support coupling the drive unit housing to the ladder frame in a differential-side end region of the drive unit housing, the two couplers of the motor-side support being arranged father outside in a vehicle width direction than the differential-side support; wherein the differential-side support couples the drive unit housing to the ladder frame by two couplers arranged in the differential-side end region of the drive unit housing; wherein the two couplers of the motor-side support and the two couplers of the differential-side support are arranged such that a virtual line connecting the two couplers of the motor-side support and the two couplers of the differential-side support forms a trapezoid that is line symmetric in the vehicle width direction with a line between the two couplers of the motor-side support being a lower base in plan view from above the vehicle. 2. The vehicle drive apparatus of claim 1 , wherein a virtual line connecting the two couplers of the motor-side support is parallel to the vehicle width direction. 3. The vehicle drive apparatus of claim 1 , wherein the motor-side support is arranged at a lower position in a vehicle height direction than the differential-side support. 4. The vehicle drive apparatus of claim 1 , wherein the motor-side support is arranged at a higher position in a vehicle height direction than the differential-side support.
