Abstract

The invention relates to a pulley of an intelligent variable valve adjusting device and a preparation method thereof, belonging to the field of auto parts. The adjustment device pulley includes a pulley (1), an oil pump base plate (2) and an oil pump body (3), the oil pump base plate (2) and the pulley (1) adopt an integrated design, and the oil pump body (3) It is directly connected with the belt pulley (1) by connecting bolts (4); the powder metallurgy material used for the belt pulley (1), oil pump bottom plate (2) and oil pump pump body (3) is: FC-0205-40. The method is as follows: treating the pulley of the powder metallurgy intelligent variable valve adjusting device with water vapor at 550°C±50°C for 2h±0.5h. The material and manufacturing costs of the invention are relatively low.

Description

(1) Technical field [0001] The invention relates to an intelligent variable valve adjusting device pulley and a preparation method thereof. It belongs to the field of auto parts. Especially in the field of powder metallurgy auto parts. (2) Background technology [0002] With the development of the world economy, the reserves of non-renewable energy such as petroleum are getting less and less, which makes governments of all countries encourage the research and development of products that reduce energy consumption. Intelligent variable valve adjustment device (hereinafter referred to as VVT) is an automobile fuel-saving device newly launched by major international automobile factories. The main working principle is to use the device to adjust the height of the intake and exhaust ports when the car engine is working, so as to use the energy of the residual combustion gas in the cylinder and adjust the engine output torque in time according to the driving conditions of the ca...
