Abstract
The utility model relates to a mounting structure of an automobile engine, which comprises an engine, a left suspension, a right suspension and a rear suspension, wherein the left suspension and the right suspension are positioned on the two sides of the engine to connect the engine and an auto body; and the rear suspension mainly comprising a large damping sleeve, a small damping sleeve, a connection plate and a support frame is fixedly mounted on the auto body and is connected with the engine through a driving bracket on one side of the engine. The mounting structure has the advantages of better damping effect, simple structure, low cost, and smaller area occupation in an engine cabin.
Description
Technical field
The utility model relates to the mounting structure of automotive engine.
Background technology
At present, automotive engine generally all is to adopt bush type to suspend and install with vehicle body to be connected.As shown in Figure 7, bush type suspends by bracing frame 11, outer tube 8, and inner sleeve 10 and vibration isolation rubber 7 are formed, and vibration isolation rubber combines as a whole inside and outside sleeve pipe between outer tube and inner sleeve, and outer tube is welded on the bracing frame.Driving engine suspends by bush type and installs with vehicle body that to be connected generally be to select arrange or the installation connection mode of 4 layouts at 3, be that the both sides of driving engine suspend to install with vehicle body by bush type and are connected, and driving engine preceding is or/and the rear end suspend to install with the subframe of automobile by bush type is connected.This of driving engine kind of mounting connection structure is simple, convenient, and Applicable scope is very extensive.Along with the raising of people to car load NVH level and driving comfort requirement, the suspend engine installation structure of vibration damping of secondary has at present appearred again, as shown in Figure 6, this kind mounting structure is a left side mostly, the right side suspends and the vehicle body direct connection, back (or preceding) suspends by starting the pusher side active bracket to be connected with (or preceding) end behind the driving engine, then (or preceding) suspends and is fixed on the subframe, thereby (or preceding) end behind the driving engine is realized and being connected of subframe, subframe is connected with vehicle body or car floor by several shock pads again, thereby realize driving engine and subframe, and the secondary vibration damping of subframe and vehicle body.This of driving engine kind of mounting structure complexity, difficult arrangement, and will occupy the bigger space of machinery space, many complex-shaped subframes are so increased the cost of mounting structure.
The utility model content
The purpose of this utility model provides a kind of mounting structure of automotive engine, has under the prerequisite of better effectiveness in vibration suppression, makes it simple in structure, reduces the cost of mounting structure, reduces the machinery space space that it occupies.
The mounting structure of automotive engine described in the utility model comprise that driving engine, a left side suspend, the right side suspends and after suspend, a left side suspends and the right side suspends suspends for bush type, it lays respectively at the driving engine left and right sides, with driving engine and body contact, after suspend by starting the pusher side active bracket to be connected with driving engine, suspend after described and mainly form by big vibration damping cover, little vibration damping cover, connecting panel and bracing frame, the axis of large and small vibration damping cover is parallel to each other, be made up of outer tube, inner sleeve and therebetween vibration isolation rubber, inside and outside sleeve pipe combines as a whole by vibration isolation rubber; One end of connecting panel is welded with little axle sleeve, and the other end has two parallel adapter plates, and little vibration damping cover is installed in the little axle sleeve and little axle sleeve interference fit; Be welded with large shaft sleeve on the bracing frame, big vibration damping cover is installed in the large shaft sleeve and the large shaft sleeve interference fit, and big vibration damping cover is fixed between two parallel adapter plates of connecting panel by bolt; After suspend and apply mechanically bolt by little vibration damping and be connected with starting the pusher side active bracket, and be fixed on the vehicle body and body contact by bracing frame.
The mounting structure of automotive engine described in the utility model only by left and right suspend and after suspend and the vehicle body direct connection, so structure is very simple; After suspend owing to have a large and small vibration damping cover, suspend after making and actually possessed two bush types and suspend, little vibration damping cover is connected with starting the pusher side active bracket, the connecting panel that suspends after passing to after the exciting of driving engine reduced, realize the one-level vibration damping, the bracing frame that the vibration of connecting panel suspends after passing to by big vibration damping cover passes to vehicle body then, thereby realized the secondary vibration damping, so can make this mounting structure have better effectiveness in vibration suppression.The utility model has been cancelled the subframe of existing mounting structure, has reduced the space of its machinery space that occupies, and greatly reduces the cost of engine installation structure simultaneously, can satisfy the NVH performance requriements of car load preferably.
