Abstract

The utility model relates to a heavy truck engine suspension device. The problem that an existing engine suspension structure is small in limitation of static rigidity scope can be solved through the engine suspension device with an outer framework and a vulcanizing body. The heavy truck engine suspension device comprises the outer framework, an inner framework and the vulcanizing body with inserting pieces, wherein the outer framework, the inner framework and the vulcanizing body are integrally formed, the outer framework is composed of a Y-direction limiting face and a hollow cavity which are connected with a beam, the left inner side and the right inner side of the hollow cavity are an X-direction limiting face, and inserting grooves are arranged at the upper end and the lower end of the X-direction limiting face. The inner framework comprises inserting feet, a boss connected with an engine and two lower side faces, the upper surface and the lower surface of each inserting foot are provided with rubber to form a Z-direction limiting face, and the two lower side faces are respectively parallel to the X-direction limiting face of the outer framework. The vulcanizing body and the two lower side faces of the inner framework are integrated in a vulcanization mode, the inserting feet of the inner framework are inserted in the hollow cavity of the outer framework and connected with the hollow cavity in a fastening mode, and the inserting pieces of the vulcanizing body are inserted in the inserting grooves at the upper end and the lower end of the X-direction limiting face of the outer framework. A wedge-shaped structure is adopted in the heavy truck engine suspension device, suspension position and the static rigidity are matched reasonably, and the service life of the heavy truck engine suspension device is prolonged.

Description

A kind of heavy duty truck engine suspends

Technical field

The utility model relates to a kind of engine mounting, and particularly a kind of heavy duty truck engine suspends.

Background technology

At present, heavily blocking in the industry, suspension structure of engine mostly is greatly shearing-type or compression-type, if it is little to obtain the quiet range in stiffness limitation of rational power system decoupling zero rate and this version of frequency distribution, thereby can not get good vibration control, affect stability and the ride comfort of car load.

Summary of the invention

The utility model has solved the little problem of present Structural Static range in stiffness limitation by carrying a kind of engine mounting with outer skeleton and sulfuration body.

The utility model is realized by following technical scheme:

A kind of heavy duty truck engine suspends, comprise integrated outer skeleton, inner frame and with the sulfuration body of inserted sheet, outer skeleton is comprised of the Y-direction confined planes and the cavity that are connected with crossbeam, and two inboards are the X-direction confined planes about cavity, and X-direction confined planes upper and lower side is with slot;

Inner frame comprises pin, the boss that links to each other with driving engine and two downsides, respectively with rubber, forms the Z-direction confined planes on the upper surface of pin and the lower surface, and two downsides are parallel with the X-direction confined planes of outer skeleton respectively;

Sulfuration body and inner frame two downsides are sulfided into one, and the cavity that the pin of inner frame inserts outer skeleton also is fastenedly connected, the outer skeleton X-direction confined planes upper and lower side of inserted sheet insertion that vulcanizes body with slot in.

Sulfuration has the steel plate of regulating self quiet rigidity size in the sulfuration body.

The sulfuration body is parallelogram sturcutre.

The utility model adopts wedge structure to suspend, Proper Match suspended position and quiet rigidity, and raising suspends service life.

The specific embodiment

Embodiment:

Shown in Fig. 1-5, the utility model is that a kind of heavy duty truck engine suspends (in the present embodiment, driving engine placement parallel with crossbeam, X-direction is direction of traffic, y is to being and the crossbeam vertical direction, z is to being direction perpendicular to the ground), comprise integrated outer skeleton 1, integrated inner frame 2 and with the sulfuration body 3 of inserted sheet 12, outer skeleton is comprised of the Y-direction confined planes 4 that is connected with crossbeam and cavity 5, cavity about 5 two inboards are X-direction confined planes 6, and X-direction confined planes upper and lower side is with slot 7

Boss 9 and two downsides 10 that inner frame 2 comprises pin 8, links to each other with driving engine respectively with rubber, form Z-direction confined planes 11, two downsides 10 parallel with the X-direction confined planes 6 of outer skeleton 1 respectively on the upper surface of pin 8 and the lower surface,

Sulfuration body 3 is sulfided into one with inner frame 2 two downsides 10, and the cavity 5 that the pin 8 of inner frame 2 inserts outer skeleton 1 also is fastenedly connected, X-direction confined planes 6 upper and lower sides of the outer skeleton 1 of inserted sheet 12 insertions of sulfuration body 3 with slot 7 in.

The effect of the rubber on the Z-direction confined planes 11 of inner frame 2 is to reduce the vibration of driving engine and spacing.

In order to regulate self quiet rigidity size, can to vulcanize in the sulfuration body 3 steel plate 13 is arranged.Vulcanize simultaneously body 3 and be parallelogram sturcutre.

The X-direction confined planes 6 of the utility model China and foreign countries skeleton 1 adopts wedge structure, and Proper Match suspended position and quiet rigidity have improved the service life that suspends.For Theoretical Design provides more quiet stiffness tuning space, alleviate simultaneously the excitation band of driving engine to the vibration of car load, play better spacing to part movement interference on every side, improve stability and the ride comfort of car load, and the equal limited location of XYZ three directions, dynamic assembly is avoided and the movement interference of part generation on every side on extreme displacement.This wedge shape symmetrical structure is easily received compression and shear deformation at work, simultaneously elastomer portion is designed to parallelogram sturcutre and can also eliminates the suffered flexure stress that suspends, this wedge shape is suspended at 3 rigidity on the direction and can be decided by bulk and angle, for the rigidity adjustment on all directions is provided convenience.
