Embodiment Construction

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

[0017] as attached figure 2 and image 3 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 bush 3 and i...

Abstract

The invention discloses an automobile power assembly suspending cushion with a vibration absorbing function, which comprises a metal frame, a rubber bushing, a core shaft and a dynamic vibration absorber. The dynamic vibration absorber is arranged on the core shaft, the dynamic vibration absorber is of a shape identical to the shape of the part of the core shaft except the extension shaft and is provided with at least two bolt holes corresponding to the core shaft for connection with a power assembly bracket, and the dynamic vibration absorber and the core shaft are connected to a bracket on the driving side of an engine through bolt assembly. Due to the dynamic vibration absorber additionally arranged on the core shaft, the invention can better isolate the vibration of the engine from being transmitted to the automobile body. Moreover, since the shapes of the dynamic vibration absorber and the core shaft are designed to be identical, the invention can be arranged conveniently and is more applicable to forecabins with small space.

Description

technical field [0001] The invention belongs to the technical field of automobile powertrain suspension systems, and in particular relates to an automobile powertrain suspension cushion assembly 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 stringent requirements for vehicle vibration and noise control, this puts forward higher requirements for the design of the powertrain suspension system, requiring maximum isolation of the transmission of powertrain vibration to the car body. [0003] Ordinary suspension cushion structure is mainly based on bushing type: it is composed of metal skeleton and rubber bushing, such as attached figure 1 As shown, the two through holes under the...
