Abstract
The utility model discloses a ventilation rubber pipe of an automobile engine crank case, which is connected between the engine crank case and an air inlet manifold branch. The rubber pipe is provided with an inner layer structure and an outer layer structure, wherein the inner layer (1) is an oil proof layer, and the outer layer (2) is a damping thermal insulation layer; and the inner layer (1) is made of FPM (fluororubber), and the outer layer (2) is made of PUR (Polyurethane) foamed rubber. The ventilation rubber pipe of the automobile engine crank case, which is provided by the utility model, is connected between the engine crank case and the air inlet manifold branch, and the function of cooling the crank case is realized through ventilating in the rubber pipe so as to effectively prevent the corrosive action of engine oil to the rubber pipe; and high temperature outside the rubber pipe can be stopped, and meanwhile, after the rubber pipe is assembled, the connecting parts of the rubber pipe can be guaranteed to have good sealing performance.
Description
Technical field
The utility model relates to a kind of automobile engine crankshaft case ventilation rubber pipe, and this rubber pipe is connected between engine crankcase and the intake manifold.
Background technique
The crankcase of motor is the important working position of motor.Motor in the course of the work, the bent axle that is arranged in the crankcase returns stirring lubricant oil, thereby produces heat; Have good ventilation and heat performance in order to ensure engine crankcase, between engine crankcase and intake manifold, be connected ventilation duct.
In the existing technology, the rubber pipe that this ventilation duct generally adopts rubber material to process.Actual demand according to above-mentioned application scenarios; This rubber pipe is connected between engine crankcase and the intake manifold; Through in rubber pipe, ventilating, also need intercept the outside high temperature of rubber pipe in addition, and this rubber pipe also need have excellent sealing performance to play the function of cooling crankcase.Thus it is clear that, the mechanism design of rubber pipe has been improved higher requirement.How to propose a kind of rubber pipe to satisfy above-mentioned performance requirement, become the technical problem that those skilled in the art become to like solution.
The model utility content
Problem to the existing technology existence; The purpose of the utility model is to propose a kind of rubber pipe; Be connected between engine crankcase and the intake manifold playing the function of ventilation and heat, and can intercept the outside high temperature of rubber pipe, have excellent sealing performance simultaneously.
For reaching this purpose, the utility model adopts following technological scheme:
A kind of automobile engine crankshaft case ventilation rubber pipe is connected between engine crankcase and the intake manifold, and this rubber pipe has inside and outside double-layer structure, and wherein internal layer is the oil resistant layer, and skin is the vibration damping thermal-protective coating.
Preferably, said internal layer is FPM, and said skin is the PUR bipeltate.
Preferably, said internal layer is formed by the FPM sulfuration.
Preferably, said skin is on the outer wall of said internal layer, to be formed by the PUR foaming.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
A kind of automobile engine crankshaft case ventilation rubber pipe that the utility model proposes; Be connected between engine crankcase and the intake manifold; Through in rubber pipe, ventilating to play the function of cooling crankcase; Can effectively prevent the corrosive action of engine oil, and can intercept the outside high temperature of rubber pipe, can guarantee that its joint has excellent sealing ability after the rubber pipe assembling simultaneously rubber pipe.
Description of drawings
Fig. 1 is the structural representation of a kind of automobile engine crankshaft case ventilation rubber pipe of the utility model proposition.
Embodiment
Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and through embodiment:
As shown in Figure 1, the structural representation of a kind of rubber pipe that proposes for the utility model.
With reference to accompanying drawing, a kind of automobile engine crankshaft case ventilation rubber pipe that the utility model proposes is connected between engine crankcase and the intake manifold.This rubber pipe has inside and outside double-layer structure, and wherein, internal layer 1 is the oil resistant layer, and outer 2 is the vibration damping thermal-protective coating.
In a preferred embodiment, internal layer 1 adopts the FPM of anti-engine oil, and the physical property of FPM is: anti-engine oil, 150 ℃ * 94h, Shao Er hardness variation ± 8 degree, weight change ± 5%, breaking strength＞6N/mm2, elongation at break＞150%; The bent axle loop around test is according to standard P V3936, and after 6 circulations, Shao Er hardness variation ± 5 are spent, weight change＜5%, breaking strength＞6N/mm2, elongation at break＞250%.
Outer 2 is the PUR bipeltate, and the physical property of PUR bipeltate is: high temperature resistant, operating ambient temperature is-40 ℃～+ 130 ℃, and density is 0.1g/cm2, and has damping, heat insulation function.
The above-mentioned automobile engine crankshaft case ventilation rubber pipe that the utility model proposes; Be connected between engine crankcase and the intake manifold; Through in rubber pipe, ventilating to play the function of cooling crankcase; Can effectively prevent the corrosive action of engine oil, and can intercept the outside high temperature of rubber pipe, can guarantee that its joint has excellent sealing ability after the rubber pipe assembling simultaneously rubber pipe.It is thus clear that, the above-mentioned rubber pipe that the utility model proposes, each item performance all can satisfy the job requirement under the actual application environment.
The automobile engine crankshaft case ventilation rubber pipe that the utility model proposes can first moulding internal layer 1, moulding skin 2 on the architecture basics of internal layer 1 then in forming process.For example, internal layer 1 is formed by the FPM sulfuration, and outer 2 is on the outer wall of internal layer 1, to be formed by the PUR foaming.
Combine accompanying drawing that the utility model is described above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
