Abstract

The invention discloses a power assembly suspension structure for a light commercial vehicle. The structure comprises a suspension support, a suspension cushion assembly and a suspension bracket, wherein the two sides of the suspension support are fixedly connected with an upper framework of the power assembly and an upper framework of the suspension cushion assembly respectively, a fixing bolt isarranged on the bottom face of a lower framework of the suspension cushion assembly, and a suspension bracket is of a V-shaped plate-shaped structure; a fixing device comprises a first connecting plate and a second connecting plate, the first connecting plate is fixedly connected with a longitudinal member, the upper end of the second connecting plate is fixedly connected with the lower end of the first connecting plate, the middle of the second connecting plate is fixedly connected with a fixing bolt through a longitudinally-formed long circular through hole, and the position where a lower semicircle of the long circular through hole is located is a fixing point; The fixing bolt is inserted into the long circular through hole during assembly, slides to the position of the lower semicircle under the action of gravity, and then is fixed; assembly efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of light commercial vehicles, and in particular relates to a power assembly suspension structure for light commercial vehicles and an assembly method thereof. Background technique [0002] The automotive powertrain suspension system is installed between the powertrain and the frame assembly. It is mainly used to support the powertrain, reduce and isolate the vibration energy of the powertrain from being transmitted to the side of the frame, and improve the driving comfort of the drivers and passengers. . The majority of light commercial vehicle engines are four-cylinder engines, and the powertrain mounting system mostly adopts a 3-point or 4-point mounting structure. [0003] The production line of light commercial vehicles has a fast pace, and has high requirements for the convenience of assembly of various system components. The powertrain assembly station is particularly demanding, so the design of the ...
