Abstract
The invention discloses a left suspension assembly for an engine. The left suspension assembly for the engine comprises a left suspension and a left suspension support. The left suspension comprises a vehicle body connecting frame, a supporting arm and a rubber bush. The rubber bush comprises an annular shell, a metal core, first rubber and second rubber. The first rubber comprises an annular part and a splayed part. The inner walls of the portions, opposite to the upper left portion and the upper right portion of the metal core, of a rubber part of the second rubber are serrated. The vehicle body connecting frame comprises an upper left suspension support, a lower left suspension support and a left suspension limiting board. The upper left suspension support, the lower left suspension support and the left suspension limiting board are all sheet metal parts. The left suspension support is a casting and comprises three suspension installation columns and three transmission installation columns. By the adoption of the left suspension assembly for the engine, the situation that a suspension static rigidity curve is bent when a transmission vibrates violently can be avoided; second-stage and fourth-stage excitation of the engine can be avoided, so that resonance is prevented from occurring in the use process, and the modality requirement of the left suspension support and the carrying boundary requirements of the engine and a whole vehicle are met; and the vehicle body connecting frame is a combined frame formed by welding the sheet metal parts and the air filter installation function is integrated.
