A subframe assembly, includes subframe body and for the above-mentioned any one shock absorbing bushing of auxiliary connection vehicle frame body and vehicle body.
A power actuated vehicle, described vehicle uses above-mentioned subframe assembly.
Useful technique effect of the present invention is:
1, the absorption portion vibrating noise of can decaying, reduces the vibrating noise that is delivered to vehicle body, improves the traveling comfort of car load;
2, bush structure of the present invention, on mount pad between rubber and lining main body, lining main body lower surface rubber and install between washbowl and all have rubber filling, can play soft position-limiting action;
3, the pad on mount pad can carry out larger area with vehicle body mounting hole and contacts, when there is some deviations in body cutout position form and position tolerance, can be by rubber infinitesimal deformation in body of rubber, subframe and vehicle body can be fitted better, thereby solve the problem of moment decline, bolt looseness and abnormal sound.
4, when position degree, planeness and the squareness of vehicle body mounting hole site have certain deviation, shock absorbing bushing of the present invention can make up this defect, makes the zero-lash laminating of subframe and vehicle body, solves the problems such as Bolt Torque decline, loosening, abnormal sound.
