Embodiment

[0028] The powertrain suspension device shown in FIG. 4 and FIG. 5 includes an inner tube 1 , an outer tube 2 arranged outside it, and an intermediate tube 3 is arranged between the inner tube 1 and the outer tube 2 . The outer tube 2 is cylindrical, the middle tube 3 is cylindrical, and they are arranged concentrically; and the periphery of the inner tube 1 is square. A first elastic body 4 is arranged between the inner pipe 1 and the middle pipe 3 , and a second elastic body 5 is arranged between the middle pipe 3 and the outer pipe 2 . Both the first elastic body 4 and the second elastic body 5 are made of rubber. The first elastic body 4 is provided with two axially arranged through holes 6 arranged uniformly, and the second elastic body 5 is provided with four axially arranged evenly arranged through holes 6 . The cross-sectional shape of the through hole 6 is large at both ends and small at the middle. The upper and lower ends of the inner tube 1 are provided with prot...

Abstract

The present invention involves the structure modification of dynamic power assembly suspending device used for vehicle damping and noise reducing. It includes inner pipes and outer pipes installed out inner pipes, it is characterized by: a central pipe is installed between said pipe and outer pipe, the first elastic body is installed between the inner pipe and central pipe and the second elastic body is installed between the central pipe and outer pipe. Thereby, the advantages of the invention as follows: 1. rational design, simple structure, it can effectively reduce vibration and noise in various conditions; especially the damping and noise reducing effect is good under the idle condition, general acceleration condition and condition; 2, good work stability, reasonable forcing situation, it greatly reduces the stress concentration phenomenon significantly, and effectively extends the use life; 3. convenient assembly, low production cost and easy use .

Description

technical field [0001] The invention relates to an automobile part, in particular to a structural improvement of a power assembly suspension device used for automobile vibration and noise reduction. Background technique [0002] The vibration of the powertrain mounting system is a part of the vibration of the vehicle. It has a great impact on the vibration of the vehicle body and the noise level in the cabin. The quality of the suspension system design will directly affect the vibration and noise level of the vehicle. An important factor affecting ride comfort. The main vibration source of the automobile powertrain suspension system is the reciprocating unbalanced inertial force and moment fluctuation generated by itself during the working process. In addition, when the car is running on various roads, the vibration excitation caused by the unevenness of the road surface will also interact with the powertrain. Influenced into the suspension system. Therefore, the main func...
