Abstract

The invention provides a powertrain mount structure of a vehicle, capable of performing positional adjustment of an elastic roller of the powertrain withnot reducing the rigidity of the vehicle body.The powertrain mount structure comprises mount support portions (A, B) to attach a powertrain (13) to a pair of right-and-left front side frames (2), wherein the mount support portions (A, B) includemount rubbers (32, 33) and mount brackets (30, 31, 42), respective longitudinal distances between plural attaching points of the right-and-left vehicle-body-side mount brackets (32, 33) are set to belonger than those of the right-and-left mount rubbers, and the mount rubbers (32, 33) are configured such that longitudinal positions thereof are changeable in a range between the plural attaching points of the mount brackets (31, 42).

Description

technical field [0001] The present invention relates to a powertrain assembly structure of a vehicle. In the powertrain assembly structure of a vehicle, left and right front side frames extending in the front-rear direction of the vehicle are provided on the left and right sides of the engine compartment. The side frame is provided with an assembly support portion for assembly and support of the power assembly. Background technique [0002] In general, a powertrain includes an engine and a transmission, and the powertrain is mounted and supported by left and right front side frames serving as vehicle body strength members via mounting support portions. [0003] In addition, the above-mentioned assembly support part is equipped with assembly rubber pads and assembly brackets, and the elastic roller of the power assembly determined by the rigidity of the assembly pad and the assembly support position is inconsistent with the inertial axis determined by the mass distribution of...
