Abstract
A subframe arrangement is configured for a mobile vehicle chassis assembly to enhance isolation of the subframe platform and drive mechanism from flex in the chassis assembly caused by dynamic forces associated with operation of the chassis assembly. The chassis assembly includes a frame having a front and a rear frame support, and a pair of elongated frame side supports interconnected therebetween. The subframe arrangement includes a subframe platform configured to receive the drive-unit, and a plurality of subframe mounting couplings operable to attach the subframe platform to the pair of elongated frame side supports. Each of the plurality of subframe mounting couplings is located along a generally isosceles triangular-shaped arrangement that enhances isolation of the subframe arrangement and attached drive unit.
