Embodiment Construction

[0038] The manufacturing method of the oil guide cover for the dual clutch of an automobile transmission [10010137] will be further described in detail below with reference to a specific embodiment.

[0039] The structure of the oil guide cover for the dual clutch of an automobile transmission is as Figure 1~3 As shown, the manufacturing method sequentially includes the following steps:

[0040] (1) Material preparation

[0041] Use high-grade carburized bearing steel bars [Steel No. G20CrMoA——GB / T3203], according to engineering

[0042] The craft requires the length of blanking to be blank. High-grade carburized bearing steel has the advantage of low price and good workability. After proper heat treatment, its strength and wear resistance can fully meet the performance of tool steel oil guide, which not only reduces the cost but also fully meets the requirements of use. Of course, you can also choose high-grade carburized steel bars such as 20CrMoA to make forging blanks.

Abstract

The invention provides a manufacturing method of an oil guide cover for a vehicle transmission double clutch. The manufacturing method comprises the steps of: selection of high-grade carburized bearing steel rod to discharge-forging to a blank-normalization-machining to a roughly machined part-carburization-quenching-whole-diameter correction by a special corrector-tempering and first polishing-pregrinding-first destressed tempering-secondary polishing-rough grinding-secondary destressed tempering-third polishing-fine grinding-demagnetization-cleaning and drying-inspection and warehousing. The method used for manufacturing the oil guide cover for the vehicle transmission double clutch can reduce the cost, and can guarantee the interference press-fit performance, the use working performance and the wear life of the oil guide cover.

Description

Technical field [0001] The invention relates to a manufacturing method of automobile parts, in particular to a manufacturing method of an oil guide cover for a dual clutch of an automobile transmission. Background technique [0002] The transmission is used to change the torque and speed transmitted from the engine to the driving wheel. The purpose is to obtain different traction and speed for the car under various driving conditions, while enabling the engine to work in the most favorable industrial and mining range. There are two types of transmissions: manual transmission and automatic transmission. The automatic transmission dual clutch is directly supplied with pressure oil by the oil pump, and the pressure oil enters the double clutch cavity through the lubrication system. The oil guide device is to effectively deliver the pressure oil output by the oil pump to the double clutch cavity to realize the clutch function of the double clutch. [0003] The oil guide cover needs t...
