Abstract

The utility model discloses a heat insulation shield installation anti-vibration gasket for an automotive engine. The heat insulation shield installation anti-vibration gasket comprises a U-shaped ring which is fixedly arranged on a heat insulation shield of an engine, wherein two sides of the U-shaped ring are respectively provided with an opening and are respectively provided with an inner opening type U-shaped ring and an outer opening type U-shaped ring, which are riveted with each other; a stainless steel screen is fixedly connected between each inner opening type U-shaped ring and the inner wall of the corresponding opening; a heat insulation piece is riveted into each outer opening type U-shaped ring. According to the heat insulation shield installation anti-vibration gasket for the automotive engine, an aluminum plate of a heat insulation shield base body is prevented from directly contacting a heat source, the temperature of the heat insulation shield is reduced, the contact area of the heat insulation shield base body and a vibration source is decreased, the vibration conduction and impact of the heat insulation shield are avoided, a sound insulation effect is achieved, secondary adjustment is not needed during assembly, and the assembly efficiency is improved.

Description

Automotive-type engine heat shield is installed Shockproof gasket

Technical field

The utility model relates to auto parts and components field, and specifically a kind of automotive-type engine heat shield is installed Shockproof gasket.

Background technique

Motorcar engine and gas exhaust manifold are worked under the condition of high temperature, because of frequent vibration, produce a large amount of noises, need to separate with thermal shield, conventional mounting mode is that thermal shield directly connects with motor or gas exhaust manifold, like this because the direct thermal shield of vibration source connects, do not have and intercept excitation vibration source, soundproof effect is poor, more to the indoor transmission noise of car, reduces riding comfort; Thermal shield directly contacts with thermal source, and heat conduction makes thermal shield self-temperature too high, may cause other electric components because of excess Temperature, and the function of losing the job reduces working life; Thermal shield is directly connected on motor and gas exhaust manifold boss by bolt, along with motor and gas exhaust manifold work long hours, may produce loosening; In addition along with car lightweight, thermal shield material makes aluminium sheet into by traditional alclad sheet, thermal shield intensity can reduce greatly, in production or transportation process, easily make product slight deformation, because thermal shield is to install by position, hole, when distortion makes thermal shield assembling, mounting center hole and motor and gas exhaust manifold boss hole position produce deviation, cannot assemble, during assembling, product needs on-the-spot adjustment, has increased cost, has reduced efficiency of assembling.

Model utility content

The purpose of this utility model is to provide a kind of simple in structure, reasonable in design and practical automotive-type engine heat shield Shockproof gasket is installed, and to strengthen heat insulation, the vibration damping usefulness of thermal shield, improves installation efficiency, reduces production costs.

The technical solution of the utility model is as follows:

A kind of automotive-type engine heat shield is installed Shockproof gasket, include the U-shaped ring being fixedly mounted on engine heat shield, it is characterized in that: the both sides of described U-shaped ring are respectively equipped with opening, include the U-shaped ring of inside and outside opening of riveted joint mutually, between the U-shaped ring of described inner opening and the inwall of opening, be fixedly connected with Stainless Steel Cloth, in the U-shaped ring of described outward opening, riveted joint has thermal insulation barriers.

Described automotive-type engine heat shield is installed Shockproof gasket, it is characterized in that: described U-shaped ring is mounted by means of bolts on engine heat shield.

The beneficial effects of the utility model:

When 1, the utility model is connected with motor or gas exhaust manifold, because the conduction of aluminium sheet heat is greater than alclad sheet, avoid thermal shield matrix aluminium sheet directly to contact with thermal source, reduced thermal shield self-temperature.

2, the utility model is connected with motor or gas exhaust manifold, and thermal shield matrix and vibration source area of contact are reduced, and has avoided conduct vibrations and the impact of thermal shield itself, has played deadening.

3, stainless steel steel wire has certain interval along plane 360o between U-shaped ring and the U-shaped ring of inner opening, make so U-shaped ring move along plane 360o certain interval upper and lower, left and right, even if thermal shield product produces slight deformation in producing or transporting, also can be compensated in mounting hole site and central position, do not need secondary adjustment, improved efficiency of assembling.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Embodiment

Referring to Fig. 1, a kind of automotive-type engine heat shield is installed Shockproof gasket, include the U-shaped ring 1 being fixedly mounted on engine heat shield, the both sides of U-shaped ring 1 are respectively equipped with opening 4, include the

U-shaped ring

2,3 of inside and outside opening of riveted joint mutually, between the U-shaped ring 2 of inner opening and the inwall of opening 4, be fixedly connected with Stainless Steel Cloth 5, the interior riveted joint of the U-shaped ring 3 of outward opening has thermal insulation barriers 6.

In the utility model, U-shaped ring 1 is fixedly mounted on engine heat shield by bolt 7.

Claims

1. an automotive-type engine heat shield is installed Shockproof gasket, include the U-shaped ring being fixedly mounted on engine heat shield, it is characterized in that: the both sides of described U-shaped ring are respectively equipped with opening, include the U-shaped ring of inside and outside opening of riveted joint mutually, between the U-shaped ring of described inner opening and the inwall of opening, be fixedly connected with Stainless Steel Cloth, in the U-shaped ring of described outward opening, riveted joint has thermal insulation barriers.

2. automotive-type engine heat shield according to claim 1 is installed Shockproof gasket, it is characterized in that: described U-shaped ring is mounted by means of bolts on engine heat shield.
