Abstract

A mounting system for a powertrain of a vehicle may secure a sufficient installation space inside of vehicle body frames and greatly reduce a height difference between the center of gravity of a motor-reducer assembly and insulators, thus greatly improving NVH performance of the vehicle. The mounding system includes: mounting units to mount the powertrain of the vehicle to the vehicle body frames. Each mounting unit includes: a vehicle body-side bracket coupled to the vehicle body frame, a powertrain-side bracket coupled to the powertrain, and an insulator installed between the vehicle body-side bracket and the powertrain-side bracket. The vehicle body-side bracket as coupled to an outer surface of the vehicle body frame extends downwards from the vehicle body frame, and thus, the vehicle body-side bracket and the insulator are located in an outer space of the vehicle body frame.

Dependent claims

A mounting system for a powertrain of a vehicle, the mounting system comprising:

mounting units configured to mount the powertrain to a first vehicle body frame and a second vehicle body frame, which are disposed on both sides of the vehicle and extended in a forward and backward direction of the vehicle,
wherein each mounting unit of the mounting units comprises:
a vehicle body-side bracket,
a powertrain-side bracket and
an insulator installed between the vehicle body-side bracket and the powertrain-side bracket and configured to insulate a vibration,
wherein the vehicle body-side bracket and the powertrain-side bracket are fixed to a corresponding vehicle body frame among the first and second vehicle body frames, and
wherein the vehicle body-side bracket as coupled to an outer surface of the corresponding vehicle body frame is configured to extend in a downward direction of the corresponding vehicle body frame, and the vehicle body-side bracket and the insulator are located in an outer space of the corresponding vehicle body frame.
