Abstract

The invention discloses an automobile power assembly suspension device, which comprises two assembly suspensions, and the two assembly suspensions are symmetrically installed on the engine. Device, core and bottom plate, the elastic main spring and the core are fixed by vulcanization, a cavity is formed between the elastic main spring and the bottom plate, the buffer device is installed inside the core, and the outside of the bottom plate A fixed plate is installed, the fixed plate is connected to the frame by welding, the core is installed in the limit cover, and the powertrain suspension can effectively reduce vibration and noise under various working conditions, especially Especially in idling conditions and general acceleration and cruising conditions, the vibration and noise reduction effect is good, especially the use of a new type of elastic main spring can better reduce vibration and noise, and the service life is greatly improved, making the driving environment comfortable for drivers and passengers The degree is more perfect, and the service life of vehicle components is greatly improved.

Description

technical field [0001] The invention belongs to the field of suspension systems, in particular to a vehicle power assembly suspension device. Background technique [0002] The powertrain mount is a part of the vibration of the whole vehicle. It has a great influence on the vibration of the body and the noise level in the cabin. The design of the mount will directly affect the vibration and noise level of the whole vehicle. An important factor for ride comfort. The main vibration source of the vehicle powertrain mount is the reciprocating unbalanced inertial force and moment fluctuations generated by itself during the working process. The excitation will also have an impact on the powertrain mount, so the main function of the automotive powertrain mount can be divided into two aspects, reducing the transmission of powertrain vibration to the body and controlling the displacement of the powertrain. [0003] The patent with the publication number CN102691746A and titled "A Hyd...
