Suspend about a kind of driving engineTechnical field
Suspend about the present invention relates to a kind of driving engine.
Background technology
Driving engine is the heart of automobile, the quality of its performance directly decides every in-use performance of automobile, because driving engine itself is a soruce of vibration, simultaneously, be subject to the various obstacle of vibrations from outside, so, Engine-mount systems is set usually, to reduce vibration passing that driving engine produces to support component, or the normal operation of various obstacle of vibration driving engines from outside.
Now, the main major part using suspending cushion to suspend as power in vehicle, so the performance of suspending cushion directly affects service life of travelling comfort (riding comfort) and automobile power assembly etc. of the vibrating noise of automobile power assembly, automobile.Current mounting structure is at above all existing defects on some.
Summary of the invention
For existing problem, the object of the present invention is to provide a kind of elastic body not easily damaged, intensity good, installation is reliable, noise is little, suspend about the driving engine of ride comfort.
To achieve these goals, technical scheme of the present invention is: suspend about a kind of driving engine, comprise driving engine left and right suspending soft cushion assembly and mounting bracket, described driving engine left and right suspending soft cushion assembly comprises elastic body, upper limit position block and lower position block, it is characterized in that: described upper limit position block and the lower position block U-shaped block all for being made up of base plate and left and right sides plate, the bore of described upper limit position block is less than the bore of lower position block, on described elastic body, lower end is arranged on the middle part of upper limit position block and lower position block plate inner surface respectively, the side plate of described upper limit position block reaches in lower position block, and and have distance between the base plate of lower position block, at least one side plate of described lower position block upwards extends, the top of the extension of described lower position block is bent to form limiting section to the inside, this limiting section is positioned at the top of upper limit position block, rubber shock-absorbing sleeve is set with outside described limiting section,
The base plate upper center of described upper limit position block is provided with locating dowel pin, and the base plate of described upper limit position block is also provided with tie bolt;
The middle part of the base plate of described lower position block is provided with circular protrusions upwards, and the surrounding of the lower surface circular protrusions of described lower position block base plate is distributed with reinforced rib;
Described mounting bracket comprises the inverted U-shaped vertical contiguous block be made up of vertical plate and both sides brace panel, the lower end of the both sides brace panel of described vertical contiguous block is to downward-extension, horizontal mounting blocks is connected with between the bottom of the extension of the both sides brace panel of described vertical contiguous block, described horizontal mounting blocks is the U-shaped block of opening upwards, described both sides brace panel is welded on the two side of horizontal mounting blocks respectively, the base plate of described horizontal mounting blocks is provided with locating dowel pin mounting hole and link bolt hole, be fixed on after locating dowel pin on described upper limit position block base plate and tie bolt are each passed through locating dowel pin mounting hole and link bolt hole on the base plate of horizontal mounting blocks, the upper part of the vertical plate of described vertical contiguous block is furnished with engine mounting holes.
Adopt such scheme, in engine assembly, lower position block is connected with car load subframe bolt, and vertical contiguous block is connected with driving engine by engine mounting holes.Driving engine in the course of the work, upper limit position block is spacing by lower position block left and right, the side plate of suspension lower position block is upwards extended to form limiting section, this limiting section forms vertical spacing to upper limit position block, avoid upper limit position block to jump out lower position block, cause jumping out spacing without any direction of rear elastic body, thus elastic body will be subject to the appearance that a shearing force causes elastic body phenomenon of rupture, make whole suspension more reliable, longer service life.Be set with rubber shock-absorbing sleeve outward at limiting section, during such upper limit position block upward movement, contact with rubber shock-absorbing sleeve, rubber shock-absorbing sleeve plays the effect of buffering noise reduction, improves travelling comfort.
Be provided with circular protrusions upwards at the middle part of the base plate of lower position block, the surrounding of the lower surface circular protrusions of described lower position block base plate is distributed with reinforced rib, can increase the intensity of lower position block so on the one hand, on the other hand, improve the mode of lower position block, increase natural frequency, avoid resonance.
Mounting bracket is installed easy to connect, and vertical contiguous block and horizontal mounting blocks all adopt U-shaped structure, and make the rigidity of whole mounting bracket better like this, intensity is good, improves the mode of mounting bracket.Make the more reliable for installing driving engine of whole mounting assembly, traveling comfort is better.
In such scheme: the bottom of the biside plate of described upper limit position block is connected with damping rubber block.Play the effect of buffering noise reduction, like this, the left side plate can avoiding upper limit directly with the contacts baseplate of lower position block, thus cause noise, the traveling comfort that raising is taken.
In such scheme: described elastic body is rubber spring.
In such scheme: the side, front and back of the base plate of described lower position block is respectively equipped with installation journal stirrup.Journal stirrup is installed be used for being connected with car load subframe bolt.
In such scheme: described vertical plate is formed by connecting by upper vertical portion and arc lower part from top to bottom successively, the inner side of described upper vertical portion is welded with upper reinforcing plate, and described arc lower part rolls forward tiltedly from top to bottom gradually.The design of vertical plate makes installation more convenient.Vertical plate arranges upper reinforcing plate, increases the intensity of vertical plate, make installation more reliable.
In such scheme: the both sides of described upper reinforcing plate are respectively equipped with semi-round welding breach.So expediently the welding of brace panel and vertical plate.
In such scheme: be connected with lower reinforcing plate between the middle part of the both sides brace panel of described vertical contiguous block.The design of lower reinforcing plate improves the intensity of vertical contiguous block.
In such scheme: the extension of described both sides brace panel also turns forward from top to bottom gradually.So convenient installation, installation strength is good.
The invention has the beneficial effects as follows: engine suspension soft pad assembly structure of the present invention is simple, can realize elastomeric left and right and spacing up and down, avoid elastic body to jump out lower position block, thus cause spacing without any direction of elastic body, thus the phenomenon causing elastic body to rupture.Whole suspending soft cushion assembly is more reliable, and noise is little, long service life, and the intensity of mounting bracket is good, and structure is simple, and easily, whole mounting assembly is good for installing driving engine traveling comfort, and noise is little in assembling.
