Abstract
The utility model belongs to auto parts and components field, specifically a kind of semi-active control type engine hydraulic pressure suspension based on magnetic rheology elastic body.This half driving engine hydraulic mount comprises connection bracket, main spring skeleton, main spring, expanded film, inertia channel, magnetic rheology elastic body decoupling zero film, electromagnet, housing and tie bolt.Wherein main spring skeleton is connected with main spring sulfuration, and magnetic rheology elastic body decoupling zero film and main spring form lower liquid chamber, and expanded film and main spring enough become upper liquid chamber; Be communicated with by inertia channel between upper liquid chamber and lower liquid chamber; Electromagnet is fixed on housing.The utility model structure is simple, and magnetic rheology elastic body decoupling zero film adopts magnetic rheology elastic body to make, and can control decoupling zero film and obtain rigidity value, reach the object of vehicle damping noise reduction, and Structure and energy is simple by the magnetic induction density changing electromagnet.
Description
Technical field
The utility model is applicable to auto parts and components field, specifically a kind of semi-active control type engine hydraulic pressure suspension of automobile shock.
Background technology
In the last few years, along with the raising of people's living standard, the requirement of people's door to vehicle riding comfort is more and more higher, and automobile design is to high pulling torque, lightweight future development, thus cause engine vibration, noise to aggravate, make the NVH characteristic degradation of car load, traditional passive suspension can not meet engine vibration isolation requirement.
Utility model content
Goal of the invention of the present utility model is to provide a kind of semi-active control type engine hydraulic pressure suspension based on magnetic rheology elastic body, reduces noise, improves the NVH performance of vehicle, improves vehicle riding comfort.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of semi-active control type engine hydraulic pressure suspension based on magnetic rheology elastic body, comprise connection bracket, main spring skeleton, main spring, expanded film, inertia channel, decoupling zero film, electromagnet, housing and tie bolt, described main spring skeleton is connected with main spring sulfuration, decoupling zero film and main spring form lower liquid chamber, expanded film enough becomes upper liquid chamber with main spring, be communicated with by inertia channel between upper liquid chamber and lower liquid chamber, housing is fixed on vehicle frame by tie bolt, described decoupling zero film adopts magnetorheological elastomer material, electromagnet is fixed on housing, and electromagnet is arranged on below decoupling zero film.
Further, described electromagnet is cylindrical, and described electromagnet is positioned at Semi-active mount housing central authorities, and electromagnet is connected with housing bottom bolt, and described decoupling zero film is round rubber diaphragm.
The beneficial effects of the utility model: the utility model structure is simple, control the rigidity of decoupling zero film by the magnetic induction density controlling electromagnet, thus reduce noise, improve the NVH performance of vehicle, improve ride comfort.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
In accompanying drawing: 1, connection bracket, 2, main spring skeleton, 3, main spring, 4, expanded film, 5, inertia channel, 6, decoupling zero film, 7, electromagnet, 8, housing, 9, tie bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, semi-active control type engine hydraulic pressure suspension, comprise connection bracket 1, main spring skeleton 2, main spring 3, expanded film 4, inertia channel 5, decoupling zero film 6, electromagnet 7, housing 8 and tie bolt 9, described main spring skeleton 2 is connected by sulfuration process with main spring 3, decoupling zero film 6 adopts magnetorheological elastomer material to process, described decoupling zero film 6 is round rubber diaphragm, decoupling zero film 6 and main spring 3 form lower liquid chamber, expanded film 4 and main spring 3 form upper liquid chamber, be communicated with by inertia channel 5 between upper liquid chamber and lower liquid chamber, housing 8 is fixed on vehicle frame by tie bolt 9, described electromagnet 7 is cylindrical, described electromagnet 7 is positioned at housing 8 central authorities of Semi-active mount, electromagnet 7 is connected with bolt with bottom housing 8, electromagnet 7 is arranged on below decoupling zero film 6, electromagnet 7 controls the rigidity of top decoupling zero film 6.
This half driving engine hydraulic mount adopts magnetic rheology elastic body decoupling zero film, the rigidity of decoupling zero film 6 is controlled by the magnetic induction density controlling electromagnet 7, during low frequency, electromagnet 7 provides high magnetic induction density, decoupling zero film 6 obtains high rigidity, main spring 3 is indeformable by decoupling zero film 6 during External Force Acting, liquid in upper and lower liquid chamber is all flowed by inertia channel 5, obtains large damping, the significantly vibrations of rapid decay driving engine; During high frequency, electromagnet provides low magnetic induction density, and decoupling zero film 6 obtains Low rigidity, and main spring 3 is out of shape by decoupling zero film 6 during External Force Acting, relies on decoupling zero film 6 to obtain the vibration of up-down vibration attenuate high frequency, reduces noise, improve the NVH performance of vehicle, improve ride comfort.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
