A flexible rubber sealing ring used between an automobile engine and a radiator

Abstract

The invention provides a flexible rubber sealing ring used between an automobile engine and a radiator. One end of the flexible rubber sealing ring is connected to the shroud, and the other end is connected to the shroud of the engine. The shroud, shroud The cover and the flexible rubber sealing ring are of a split structure, in which the flexible rubber sealing ring is in the shape of a "bell mouth", and the section shape of the small end is designed in the shape of an "O-ring", and the corresponding shroud is equipped with an assembly groove; the large The "bell mouth" at the end is provided with a protective cover that matches its inner wall, so that it can be closely fitted with the protective cover in a natural state and can be relatively displaced. Its structure is simple and easy to assemble. When the vehicle is running, due to the vibration of the engine itself and the excitation of the ground, the flexible rubber sealing ring and the sealing cover can slide relative to each other. The relative movement of large displacement ensures the normal operation of the system without damaging the flexible rubber sealing ring.

Description

technical field [0001] The invention relates to auto parts, in particular to a flexible rubber sealing ring used between an auto engine and a radiator. Background technique [0002] Some models on the market are equipped with a shield cover between the engine and the radiator, so that a relatively sealed channel is formed between the engine and the radiator cover, and the purpose is to improve the heat dissipation efficiency of the engine cooling system. Due to the relatively complex structure, relatively high assembly accuracy requirements, and the engine and radiator are in a state of relative motion during vehicle driving, it is necessary to add a flexible rubber seal ring at the rear end of the seal cover to replace the rigid connection with a flexible connection. This not only reduces the difficulty of assembly, but also absorbs the vibration and noise generated during the running of the vehicle, and improves the comfort of the vehicle. [0003] And now most vehicles a...

AI Technical Summary

Problems solved by technology

[0005] 1. The assembly efficiency is low. It is necessary to manually assemble the stainless steel hoop to the rubber sealing ring in advance, and then assemble the sealing ring with the stainless steel band to the protective cover and the shroud, then tighten the band with the air gun

At the same time, there are also problems of difficult operation and improper assembly

[0006]Second, it is easy to be damaged. Rubber products are in a state of dynamic tension for a long time, which is prone to fatigue damage; when the engine or radiator vibrates with large displacement, its displacement may exceed The elastic range of the rubber flexible sealing ring causes the product to tear and break

When a large displacement occurs between the two suddenly encountering an uneven road surface, it is easy to cause tearing and damage to the flexible rubber sealing ring 3
