The utility model content
The utility model is devoted to solve in the prior art because the bush type hydraulic damping suspends and is adopted hydraulic damping to come driving engine vibration damping, vibration isolation, and is relatively poor to stronger shearing force ability to bear, complex structure, the defective that fault rate is higher.Aim to provide and a kind ofly can bear stronger shearing force, can with before and after the driving engine, up-and-down movement transfer to and rub motion, and is simple in structure, a kind of bush type engine mounting that fault rate is low.
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals: a kind of bush type engine mounting comprises the support that has the support ring; Outer shroud, interior pipe and elastic body, described elastomeric front is arcuation; Be provided with through hole wherein; Described metal inner pipe is located at elastomeric through hole, and the two ends that described elastic body is arcuation link to each other with outer shroud inwall both sides respectively, and the external annulus of said elastic body below is provided with boss; The outer shroud interference is arranged in the support ring, and the center of said boss bottom and the vertical centre of support ring squint 5 degree to the right to 20 degree; Receive the power of driving engine when metal inner pipe after; Through boss be the elastic body of arcuation and vibrationproof, the vibration-proof structure of outer shroud, can bear harsh shearing force, utilize the rubber internal friction characteristic; Front and back, the up-and-down movement of driving engine become rub motion, thereby reach the purpose of vibrationproof, vibration damping.
As preferably, the inwall of left side, elastic body top outer shroud is provided with registration mast, and the inwall of right side, elastic body top outer shroud is provided with locating piece, and registration mast is provided with contiguous block with the locating piece centre; The two ends of registration mast and locating piece and engine installation parts are adaptive, can make things convenient for the installation of driving engine like this, and the contiguous block that is provided with in the middle of registration mast and the locating piece can be strengthened the single-piece absorption capacity.
As preferably, outer shroud, boss, registration mast, locating piece, contiguous block and elastic body are India rubber and make and be sulfided into one with metal inner pipe; Such integral structure can greatly improve absorption capacity, and makes easily, and is simple in structure.
As preferably, the both ends of the surface that the both ends of the surface of registration mast protrude in the both ends of the surface of outer shroud, locating piece protrude in the both ends of the surface of registration mast, and the both ends of the surface of metal inner pipe protrude in the both ends of the surface of registration mast; The position of location engine so easily, and the both ends of the surface that can guarantee the support ring when mounted can not wiped and run into miscellaneous part.
As preferably, the support bottom is provided with 2 mounting screws; Guarantee that support can convenient, firm being installed on the vehicle frame adapting position.
Because adopt technique scheme, the beneficial effect of a kind of bush type engine mounting provided by the invention is: can bear stronger vibratory force 1.; 2. can driving engine front and back, up-and-down movement be transferred to and rub motion; 3. simple in structure, fault rate is low.
