Abstract

The utility model provides an automobile engine exhaust manifold pad, it stacks up under and plywood of plywood, well plywood including the structure exhaust manifold that becomes one, and its technical essential is: the border of a manifold pad plywood wherein department for the flange structure to the upside, the engine upper portion resin rocking arm shroud of this flange structure's position during rather than the installation engine is corresponding. The utility model has the advantages that: the efficiency of exhaust manifold is thermal -insulated is improved, make the high temperature resistant poor part around the exhaust manifold obtain better protection. Pass test, the sealed pad of this novel exhaust manifold is respond well, makes resin material's rocking arm shroud no longer warp simple structure easily production moreover because of high temperature.

Description

A kind of vehicle engine exhaust divided manifold sealing gasket

Technical field

The utility model belongs to technical field of automobile engine, particularly a kind of vehicle engine exhaust divided manifold pad with heat-insulating structure.

Background technique

As everyone knows, vehicle engine exhaust divided manifold pad is the important spare part in automobile engine exhaust system, in the prior art, in order to meet the requirement of canned motor exhaust, sealing configuration between the gas exhaust manifold of four cylinder engine and cylinder head: namely: a gas exhaust manifold sealing gasket, make sealed muscle at edge, air outlet flue position, compactedly before gas exhaust manifold and cylinder head play seal action, prevent waste gas from revealing.In actual use, owing to being one deck gasket seal, therefore easily produce following shortcoming: one is higher near cylinder head position temperature, high-temperature gas upwards flows and causes rocking arm cover cap by high temperature erosion, thus affects its working life; Although two is have thermal shield above gas exhaust manifold, complete state of thermal isolation cannot be taken to.

Summary of the invention

The purpose of this utility model is to provide a kind of vehicle engine exhaust divided manifold pad with heat-insulating structure.

The purpose of this utility model is achieved by the following technical solution: a kind of vehicle engine exhaust divided manifold pad, it includes become one structure exhaust manifold pad top plate, la m and lower plywood, it is characterized in that: be the turnup structure to upside in the edge of a manifold pad laminate wherein, the position of this turnup structure is corresponding with upper position of engine resin rocking arm cover cap during its installation motor.

The upper plate of exhaust manifold pad, middle plate and lower plate, upper plate and lower plate are made with sealed muscle shape, can play seal action as conventional seals pad; The preferably la m of this structure turns down on the upside of gas exhaust manifold, to prevent high-temperature gas from upwards flowing, plays heat-blocking action, can prevent rocking arm cover cap from receiving high temperature erosion.

The utility model has the advantages that:

Traditional scheme can only come heat insulation with the thermal shield of gas exhaust manifold, and need has larger gap between cylinder head, and effect of heat insulation is not good.

Improve gas exhaust manifold heat-insulating efficiency, the part of the high temperature resistant difference around gas exhaust manifold is better protected.

By test, this Novel exhaust manifold sealing gasket is respond well, and the rocking arm cover cap of resin material is no longer out of shape because of high temperature, and structure is simply easy to produce.

The symbol description of accompanying drawing major component: 1-upper plate, plate in 2-, 3-lower plate, 4-air discharging manifold flange, 5-gas exhaust manifold, 6-construction bolt, 7-engine cylinder cover, 8-rocking arm cover cap.

The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the right protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.

Embodiment

example 1

As shown in Figures 1 to 3, in figure 1 is exhaust manifold pad top plate (material selects Cr17Ni7), 2 is la m (material selects SPCC), 3 is lower plywood (material selects Cr17Ni7), at the turnup structure that the edge of the la m 2 of manifold pad is to upside, the position of this turnup structure is corresponding with the upper position of engine resin rocking arm cover cap 8 during its installation motor.

This la m 2 folds certain altitude by the position in upside to gas exhaust manifold rollover; gas exhaust manifold is produced to the gesture of encirclement; to prevent the direct engine corrosion top of gas exhaust manifold side high-temperature gas, reduce the temperature of upper position of engine, it is played to the effect of high temperature protection.

The technical solution adopted in the utility model comprises all by the SPCC steel plate 3-2 with " flange " structure that stamping process produces, they are welded together by the upper plate of nine solder joints and exhaust manifold pad and lower plate, and threepayer plays sealing and the heat-blocking action to upper position of engine between gas exhaust manifold and cylinder body together.

In addition, 4 in figure is air discharging manifold flange, and 5 is gas exhaust manifold, and 6 is construction bolt, and 7 is engine cylinder cover.

Claims

1. a vehicle engine exhaust divided manifold pad, it includes become one structure exhaust manifold pad top plate, la m and lower plywood, it is characterized in that: be the turnup structure to upside in the edge of a manifold pad laminate wherein, the position of this turnup structure is corresponding with upper position of engine resin rocking arm cover cap during its installation motor.

2. vehicle engine exhaust divided manifold pad according to claim 1, is characterized in that: the laminate turnup structure in described manifold pad is la m.
