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
The invention belongs to the automobile power assembly suspension system technical field, be specifically related to a kind of automobile power assembly suspending cushion assembly structure of tool shock sucking function.
Background technology
Power assembly suspension system is meant the elastic connecting system between dynamic assembly and the vehicle body, mainly plays support, vibration isolation, spacing, the good and bad ride of vehicle that directly influences of this system design.Along with the require increasingly stringent of people to automobile vibration, noise control, this just has higher requirement to the design of power assembly suspension system, requires to comprise in the whole working speed scope of driving engine that starting and idling can both isolate the transmission of engine vibration to car body effectively.
Common suspending cushion structure is mainly based on bush type: be made up of metallic framework and rubber bush, as shown in Figure 1, two through holes of connection support 2 belows of metallic framework are used to connect vehicle body, rubber bush 3 is assemblied in the cylinder frame 1 by outer tube 4, and the inner sleeve 5 of rubber bush 3 connects driving engine master end support.This suspending cushion vibration isolation mainly concentrates on certain low-frequency range, and for the intrinsic vibration characteristic of power system, common suspending cushion structure does not just have the function that the natural resonance that reduces or offsets power system encourages.
Summary of the invention
The object of the present invention is to provide a kind of suspending soft cushion assembly of powertrain system of automobile of new construction, the excitation in the time of can reducing or offset motive power system resonance.
Technical scheme of the present invention is as follows:
A kind of suspending soft cushion assembly of powertrain system of automobile, it comprises metallic framework, rubber bush and mandrel, described metallic framework is made up of with the support that is connected that is welded on its cylindrical side Monday cylinder frame; Described rubber bush is assemblied in the cylinder frame, the inwall interference fit of the outer tube of rubber bush and cylinder frame; Connecting bore with body contact is arranged on the described connection support.The projecting shaft of described mandrel inserts in the inner sleeve of rubber bush, with the inwall interference fit of inner sleeve; Be distributed with at least two and dynamic assembly support bonded assembly bolt hole on the mandrel; Connecting bore with body contact is arranged on the described connection support.
Improvement of the present invention is also to be equipped with dynamic vibration absorber on mandrel in suspending soft cushion assembly, described dynamic vibration absorber is made up of mass and sole plate, mass directly vulcanizes to sole plate by rubber, on sole plate, be welded with pin and double-screw bolt, be connected with double-screw bolt and navigate on the mandrel by pin.By increasing mandrel and dynamic vibration absorber, the vibration that can isolate driving engine better is to the car body transmission.
Described dynamic vibration absorber is installed in the mandrel position of close rubber bush, makes things convenient for the installation of dynamic assembly support like this, and also increases damping effect.
Also be welded with L shaped tie rod with connecting the relative side in support position of weld on described cylinder frame circumference, there is the connecting bore with body contact the end of tie rod, can play the effect of balance vibration like this.
The present invention is by optimizing the mandrel structure of suspending cushion, integrated dynamic vibration absorber on mandrel, reach and above metallic framework, increase L shaped metal tie rod, thereby improve the dynamic stiffness of suspending soft cushion assembly, realized comprising in the whole working speed scope of driving engine the starting and idling can both isolate the transmission of engine vibration effectively to car body, improved the NVH performance of car load and the traveling comfort of taking.
