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
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 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 isolate to greatest extent the transmission of dynamic assembly vibration to car body.
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
Goal of the invention of the present invention is to provide a kind of automobile power assembly suspending cushion with shock sucking function, the excitation in the time of can reducing or offset motive power system resonance, and also simple in structure, arrangement convenience is more suitable for the less situation in front deck space.
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; The projecting shaft of described mandrel inserts in the inner sleeve of rubber bush, with the inwall interference fit of inner sleeve, is 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 provided with a dynamic vibration absorber in suspending soft cushion assembly, be installed on the mandrel, described dynamic vibration absorber is consistent with the shape of mandrel part except that projecting shaft, also corresponding with mandrel be distributed with at least two with dynamic assembly support bonded assembly bolt hole, it is connected on the support of driving engine master end with mandrel by fitting-up bolt.By increase dynamic vibration absorber on mandrel, the vibration that can isolate driving engine better is to the car body transmission.And be consistent with dynamic vibration absorber with the shaped design of mandrel, arrangement convenience is more suitable for the less situation in front deck space.
Described dynamic vibration absorber is made up of mass and sole plate, and mass directly vulcanizes to sole plate by rubber.
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 on the mandrel original structure basis of suspending cushion, develop identical with the mandrel structure or similar dynamic vibration absorber structure, not only satisfy original spatial destribution boundary condition, the convenient layout, and can reduce or offset the motive power system excitation in when resonance, thereby isolate the transmission of engine vibration effectively, improved the NVH performance of car load and the traveling comfort of taking to car body.

The specific embodiment
Further specify structure of the present invention below in conjunction with accompanying drawing:
As accompanying drawing 2 and shown in Figure 3, suspending soft cushion assembly has rubber bush 3, metallic framework, mandrel 6, dynamic vibration absorber 7, the L shaped tie rod 8 of reinforcement metal.Metallic framework is welded by cylinder frame 1 and connection support 2, and the L shaped tie rod 8 of reinforcement metal is welded direct to cylinder frame 1 top of the metallic framework that suspends, and good more near position intermediate more.Cylinder frame 1 is used to install rubber bush 3, connects support 2 and is used to be connected vehicle body with L shaped tie rod 8.The outer tube 4 of rubber bush 3 and the round skeleton 1 inwall interference fit of metallic framework.The projecting shaft of mandrel 6 inserts in the inner sleeve 5 of rubber bush 3, with the inwall interference fit of inner sleeve 5.Dynamic vibration absorber 7 is installed on the mandrel 6.
Dynamic vibration absorber 7 adopts structure shown in Fig. 4 .1 and Fig. 4 .2, and metal quality piece 9 is directly vulcanized to sole plate 11 by rubber 10, and dynamic vibration absorber 7 is consistent with the shape of mandrel 6 part except that projecting shaft.
Three bolts hole that connect the dynamic assembly supports are arranged on the mandrel 6, on the dynamic vibration absorber 7 also correspondence be distributed with three with dynamic assembly support bonded assembly bolt hole, dynamic vibration absorber 7 is connected on the support of driving engine master end with mandrel 6 fitting-up bolts.2 through holes on the connection support 2 of metallic framework and two through holes on the L shaped tie rod 8 by bolted connection to vehicle body.
