Abstract
The invention discloses a heavy car engine rear suspension cushion assembly, and relates to the technical field of car manufacturing. The heavy car engine rear suspension cushion assembly comprises a hollow cone-shaped outer shell with holes in two ends and an inner frame arranged in a cavity of the outer shell, wherein the bigger end of the outer shell is flanged outwards, the smaller end of the outer shell is flanged inwards, and the shape of one end of the inner frame is a hexahedral hollow cavity; the shape of the other end of the inner frame is cuboid, the cuboid of the inner frame stretches out from the hole of the smaller end of the outer shell, a main rubber block and a plastic plate are radially and successively arranged between the hollow cavity of the inner frame and an inner cavity of the outer shell; the hollow cavity of the inner frame is internally and successively provided with a vibration block and a limiting block, and the limiting block props against a baffle plate, the baffle plate is fixedly arranged on the bigger end of the outer shell. The heavy car engine rear suspension cushion assembly is used for solving the problem that the existing heavy car engine damper device is time-consuming and labor-consuming in installation and poor in damping effect.
Description
Technical field
The present invention relates to field of automobile, especially a kind of for the connecting device between engine of heavy-duty car and vehicle frame.
Background technology
The driving engine of heavy motor vehicle is all be fixed on the vehicle frame of automobile usually, driving engine due to heavy motor vehicle operationally can produce larger continuous schedule vibration, this vibration is also delivered on heavy-duty automobile frame simultaneously, whole heavy motor vehicle is made to produce vibration, affect the traveling comfort that navigating mate is taken, also produce noise emission to surrounding environment simultaneously; For reducing this vibration brought by engine operation, a shock attenuation unit is set usually between driving engine and vehicle frame, to reduce vibration during engine operation; This shock attenuation unit be arranged at present between engine of heavy-duty car and vehicle frame is made up of more than one piece parts, and these parts need the time of at substantial when assembling, and effectiveness in vibration suppression is also bad.
Summary of the invention
The object of this invention is to provide a kind of rear-suspending cushion of automobile engine assembly, it can solve existing engine of heavy-duty car shock attenuation unit and install the problem time-consuming, effectiveness in vibration suppression is poor.
In order to solve the problem, the technical solution used in the present invention is:
This rear-suspending cushion of automobile engine assembly, comprise taper body skin and the inner frame be arranged in described body skin cavity of the porose hollow in two ends, the large end outward flanging of described body skin, small end are to in-flanges, the profile of described inner frame one end is hexahedral hollow cavity, its other end is cuboid, and the cuboid of described inner frame stretches out from the hole of the small end of described body skin; Between the hollow cavity and the inner chamber of described body skin of described inner frame, radial direction is provided with primary elastomeric block and plastic flagstone successively; Be disposed with damping block and limiting stopper from right to left in the hollow cavity of described inner frame, described limiting stopper abuts with plate washer, and described plate washer is fixed on the large end of described body skin.
In above technical scheme, further scheme is: described plastic flagstone, primary elastomeric block are fixed on outside the hexagon of described inner frame.
Further: described primary elastomeric block and described damping block are made up of elastomeric material.
Further: primary elastomeric block is made up of "eight" shape face, anti-"eight" shape face and connecting portion, and its cavity shape matches with the outer hexahedron of described inner frame.
Further: described plastic flagstone is arranged on the "eight" shape face of described primary elastomeric block, the outside in inverted "eight" shape face.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, structure of the present invention is reliable, assembling is convenient, and overall assembly stiffness equivalent scope is large, good damping result;
2, the present invention is integral type, can assemble in advance, save built-up time on line under fitting line.
Accompanying drawing explanation
Fig. 1 is that the present invention is main depending on cuing open figure.
Fig. 2 is that the present invention assembles decomposing schematic representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described: this rear-suspending cushion of automobile engine assembly as shown in Figure 1 and Figure 2, comprise taper body skin 9 and the inner frame 6 be arranged in body skin 9 cavity of the porose hollow in two ends, body skin 9 holds greatly outward flanging, small end to in-flanges, the profile of inner frame 6 one end is hexahedral hollow cavity, its other end is cuboid, and cuboid one end of inner frame 6 is stretched out from the hole of the small end of body skin 9; Between the hollow cavity and the inner chamber of body skin 9 of inner frame 6, radial direction is provided with primary elastomeric block 5 and plastic flagstone 4 successively, wherein the hexahedron of plastic flagstone 4, primary elastomeric block 5 and inner frame 6 sulfides, by press device, they are compressed into the inner chamber of body skin 9 again, utilize the tension force after primary elastomeric block 5 pressurized, make sulfuration body be close to the inner chamber of body skin 9, prevent sulfuration body from deviating from; Be disposed with damping block 3 and limiting stopper 2 in the hollow cavity of inner frame 6 from right to left, limiting stopper 2 abuts with plate washer 1, and plate washer 1 is fixed on the large end of body skin 9 by combination nut, prevents limiting stopper 2, damping block 3, sulfuration body from deviating from from the large end of body skin 9.
The part that the present invention mainly plays damping of vibrations is primary elastomeric block 5 and damping block 3, primary elastomeric block 5 is made up of elastomeric material, its profile is added connecting portion by "eight" shape face and inverted "eight" shape face two part and is formed, the shape of its inner chamber matches with the outer hexagon of inner frame 6, damping of vibrations that is upper and lower and left and right directions can be played, plastic flagstone 4 is fixed on the "eight" shape face of primary elastomeric block 5 and the outside in inverted "eight" shape face, plays the effect of protection primary elastomeric block 5; And the damping of vibrations of damping block 3 fore-and-aft direction by elastomeric material is made mainly; By adjusting the size of inner frame 6 and body skin 9, adjust the size of primary elastomeric block 5; By adjusting the gauge of the gauge also adjustable damping block 3 of limiting stopper 2, therefore, constructional feature of the present invention determines the rigidity that can adjust suspending soft cushion assembly very on a large scale, ensure that effectiveness in vibration suppression and the service life of whole assembly; Rivet nut bracket 7 below inner frame 6 of the present invention, nut bracket has been equipped with nut 8, the convenience mainly in order to assemble when this present invention is connected with engine cylinder body support frame.
