Composite automobile engine lubricating oil sump

Abstract

The invention relates to a composite automobile engine lubricating oil sump. The impact resistance, vibration resistance and the like of the composite engine lubricating oil sump are improved. According to the technical scheme, the oil sump is prepared from the following raw materials in part by mass: 100 parts of polyethylene terephthalate (PET), 20 to 55 parts of alkali-resistant glass fibers, 2 to 5 parts of flame retardant, 2 to 4 parts of silane coupling agent and 0.5 to 1 part of aid. The composite lubricating oil sump is prepared from the PET serving as a base material and main raw materials such as long and short glass fibers in a certain ratio, the flame retardant and the like; compared with a metal oil sump, the oil sump has the advantages of light weight, low cost, lower oil consumption, short preparation period, corrosion resistance, vibration resistance, noise reduction, no explosion and the like; and compared with the conventional nylon composite oil sump, the oil sump has the advantages that various performance indexes are improved, particularly the impact resistance is obviously improved, the working temperature range is wide, and the oil sump can work at the temperature of between -50 and 180 DEG C for a long time.

Description

technical field [0001] The invention relates to an automobile engine part, in particular to a composite automobile engine lubricating oil pan with wide temperature range, excellent performance and low cost. Background technique [0002] The oil pan is an important component of the automobile engine. It is installed at the bottom of the engine to collect and store lubricating oil, and to dissipate heat, prevent the oxidation of lubricating oil, and seal the crankcase. Automobile engine lubricating oil pans on the market are mostly stamped from thin steel plates. Automobile lubricating oil pans made of metal materials have high cost, heavy weight, high fuel consumption, high exhaust emissions, and serious environmental pollution. In addition, the development cycle of the metal oil pan is long and the development cost is high, which is not convenient for the design, manufacture and modification of automobiles. At present, some high-end models also have engine lubricating oil p...

Problems solved by technology

Automobile engine lubricating oil pans on the market are mostly stamped from thin steel plates. Automobile lubricating oil pans made of metal materials have high cost, heavy weight, high fuel consumption, high exhaust emissions, and serious environmental pollution.

In addition, the development cycle of the metal oil pan is long, the development cost is high, and it is not convenient for the design, manufacture and modification of the car

At present, some high-end models also have engine lubricating oil pans made of composite materials. The composite materials used are composed of PA66 (nylon), GF (short glass fiber) and additives. The oil pan made of this composite material The shell makes up for some deficiencies of metal materials, but it also has defects in performance such as impact resistance, vibration resistance, and noise reduction, and has a narrow operating temperature range and high cost. Therefore, to a certain extent, non-metallic materials are restricted. Oil pan applications
