Abstract

The utility model discloses a bushing type engine suspension, which is capable of bearing high shear vibration, simple in structure and low in failure rate. The bushing type engine suspension comprises a support with a support ring, an outer ring, an inner pipe and an elastic part. A through hole is arranged in the middle of the elastic part with an arc front face, the metal inner pipe is arranged in the through hole of the elastic part, two arc ends of the elastic part are connected with two sides of the inner wall of the outer ring respectively, a reinforcement block is arranged on the outer ring wall below the elastic part, the outer ring is arranged in the support ring in an interference manner, and the center of the bottom of the reinforcement block and the vertical center of the support ring skew rightwards by five to twenty degrees. The metal inner pipe under the force of an engine can bear harsh shearing force by the aid of the reinforcement block, the arc elastic part and the anti-vibration and damping structure of the outer ring, and bilateral and vertical movement of the engine can be turned into rubbing movement by means of the rubber internal friction characteristic, so that vibration proofing and vibration reduction are achieved.

At present, the engine mounting that uses on the automobile is used for driving engine and carriage junction, the stationary engine position, and it comprises the support that has the support ring, outer shroud, interior pipe and elastic body constitute.A kind of disclosed on the Chinese patent document " the bush type hydraulic damping suspends ", its publication number is CN2781080 Y, " the bush type hydraulic damping suspends " in this technical scheme; Relate generally to the elastic body that is provided with the band skeleton in the outer tube; Be provided with interior pipe in the elastic body, between elastic body and outer tube, form hydraulic cavities and be divided into epitrochoidal chamber and compensated cavity, and on runner plate, be provided with the runner that connects epitrochoidal chamber and compensated cavity by runner plate; Be installed with the decoupling zero film between said epitrochoidal chamber and outer tube; This decoupling zero film is located on the adapter plate, and said outer tube is provided with air extractor vent, and this air extractor vent communicates with cavity between said decoupling zero film and the outer tube.Its solves existing in prior technology driving engine high frequency hardening phenomenon that when high frequency, small amplitude motion, suspends, when overcoming existing bush type hydraulic damping and being suspended at high frequency, little amplitude to the technical matters of the deficiency of driving engine vibration damping, vibration isolating effect etc.But adopt hydraulic damping to come driving engine vibration damping, vibration isolation because this bush type hydraulic damping suspends, it is relatively poor to bear stronger shearing force vibration ability, complex structure, the defective that fault rate is higher.

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 it is relatively poor to bear stronger shearing force vibration ability, complex structure, the defective that fault rate is higher.Aim to provide and a kind ofly can bear the vibration of stronger shearing force, simple in structure, the 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: the bush type engine mounting comprises the support that has the support ring; Outer shroud; Interior pipe and elastic body, described elastomeric front is V-shaped, and described metal inner pipe is located in the middle of the bottom of elastic body V-arrangement; The two ends of described elastic body V-arrangement link to each other with outer shroud inwall both sides respectively; The external annulus of said elastic body top is provided with boss, and said outer shroud interference is arranged in the support ring, and the vertical centre of the center of said boss and support ring squints 18 degree left to 30 degree; Receive the power of driving engine when metal inner pipe after; Through boss and the V-shaped elastic body 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, left and right sides is arranged with locating piece on the inwall of elastic body below outer shroud, is provided with contiguous block between the locating piece; The two ends of 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 the locating piece can be strengthened the single-piece absorption capacity.

As preferably, outer shroud, boss, 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 locating piece protrude in the both ends of the surface of outer shroud, metal inner pipe protrude in the both ends of the surface of locating piece; 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 screw holes; Guarantee that support can convenient, firm being installed on the vehicle frame adapting position.

Because adopt technique scheme, the beneficial effect of bush type engine mounting provided by the invention is: 1. can bear stronger shearing force vibration; 2. simple in structure; 3. fault rate is low.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:

Embodiment 1

In the embodiment shown in the accompanying drawing 11; Described elastic body 4 positive V-shaped; Described metal inner pipe 6 is located in the middle of the bottom of elastic body 4 V-arrangements, and the two ends of described elastic body 4 V-arrangements link to each other with outer shroud 2 inwall both sides respectively, and outer shroud 2 walls of said elastic body 4 tops are provided with boss 3; Said outer shroud 2 interference are arranged in the support ring 1, the vertical centre of the center of said boss 3 and support ring 1 squint left 23 the degree; Receive the power of driving engine when metal inner pipe after,, can bear harsh shearing force through boss and the V-shaped elastic body and vibrationproof, the vibration-proof structure of outer shroud; 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, left and right sides is arranged with locating piece 5 on the inwall of elastic body 4 below outer shrouds 2; Be provided with contiguous block 7 between the locating piece 5; The two ends of locating piece and engine installation parts are adaptive, can make things convenient for the installation of driving engine like this, the contiguous block that is provided with in the middle of the locating piece; Can strengthen the single-piece absorption capacity, outer shroud 2, boss 3, locating piece 5, contiguous block 7 and elastic body 4 are the India rubber making and are sulfided into one with metal inner pipe 6; Such integral structure can greatly improve absorption capacity; And make easily; Simple in structure, the both ends of the surface of locating piece 5 protrude in the both ends of the surface of outer shroud 2, the both ends of the surface of metal inner pipe 6 protrude in the both ends of the surface of locating piece 5 (seeing Fig. 2, Fig. 3), 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, and support 8 bottoms are provided with 2 mounting screw holes 9.Guarantee that support can convenient, firm being installed on the vehicle frame adapting position.
