Embodiment Construction

[0016] Further illustrate structure of the present invention below in conjunction with accompanying drawing:

[0017] as attached figure 2 , image 3 , Figure 4 As shown, the suspension cushion assembly has a rubber bushing 3, a metal skeleton, a mandrel 6, a dynamic shock absorber 7, and a reinforced metal L-shaped brace 8. The metal skeleton is welded by the cylindrical skeleton 1 and the connecting bracket 2, and the reinforced metal L-shaped bracing 8 is directly welded to the top of the cylindrical skeleton 1 suspending the metal skeleton, and the closer to the middle position the better. The cylindrical skeleton 1 is used for installing the rubber bushing 3, and the connecting bracket 2 and the L-shaped brace 8 are used for connecting the vehicle body. The outer sleeve 4 of the rubber bushing 3 is in interference fit with the inner wall of the round frame 1 of the metal frame. The protruding shaft of the mandrel 6 is inserted into the inner sleeve 5 of the rubber b...

Abstract

The invention provides a suspension cushion assembly of a powertrain system of automobiles, which comprises a metallic framework, a rubber bushing, a mandrel and a dynamic vibration absorber, wherein a projecting shaft of the mandrel is inserted into the inner bushing of the rubber bushing, and is in interference fit with the inner wall of the inner bushing, at least two bolt holes which are connected with a support of the powertrain are distributed on the mandrel, and the mandrel is provided with the dynamic vibration absorber. By optimizing the structure of the mandrel of the suspension cushion, integrating the dynamic vibration absorber on the mandrel, and adding an L-shaped metal brace on the upper part of the metallic framework, the invention can improve the dynamic stiffness of the suspension cushion assembly, realize that the range of the working speed of rotation of an engine including the starting and idling of an engine can effectively cut off the transmission of the engine vibration to automobile body, and improve the NVH performance and the riding comfortableness of the whole automobile.

Description

technical field [0001] The invention belongs to the technical field of automobile power assembly suspension systems, and in particular relates to an automobile power assembly suspension cushion assembly structure with a vibration-absorbing function. Background technique [0002] The powertrain mount system refers to the elastic connection system between the powertrain and the body, which mainly plays the role of support, vibration isolation and limit. The quality of the system design directly affects the ride comfort of the car. As people have increasingly strict requirements for vehicle vibration and noise control, this puts forward higher requirements for the design of the powertrain suspension system, which requires that the engine can be effectively isolated within the entire operating speed range of the engine, including starting and idling. Transmission of vibrations to the vehicle body. [0003] Ordinary suspension cushion structure is mainly based on bushing type: i...
