Aluminum alloy cast iron steel automobile piston
汽车活塞是内燃机中的关键零部件,其性能的好坏直接影响汽车的动力性、燃油经济性、环保性能等。 以下是汽车活塞产品的详细介绍:
- 结构:汽车活塞通常采用铝合金或钢制成,呈圆柱形。 其结构可分为顶部、头部和裙部。 顶部是组成燃烧室的主要部分,具有平顶、凹顶、凸顶等各种形状,以适应不同的燃烧室形式和发动机要求。 头部的火花塞与气缸盖连接,底部则紧贴在气缸壁上。
- 功能:活塞的主要作用是将燃料燃烧产生的高压气体压力转化为机械运动。 在气缸内上下运动,通过连杆、曲轴机构带动汽车车轮转动。 同时活塞还负责将燃料和空气的混合气引入燃烧室,并在燃烧过程中承受高温高压气体的作用。
Machining Precision:
Because the dimensional accuracy of the piston directly affects the performance and reliability of the engine. The dimensional tolerance requirements for pistons are extremely strict, generally within 0.01 mm. Even for some high-precision pistons, the tolerance is required to be within 0.005 mm. The accuracies of roundness, cylindricity, and straightness of the piston are also of great importance, ensuring the smooth movement and sealing of the piston in the cylinder. The requirements for mutual positional accuracy are also very high, ensuring the accuracy and reliability of the piston during assembly and use.
Machining Process:
Select an appropriate piston material, such as aluminum alloy, cast iron, etc. The material needs to undergo strict inspection and testing to ensure that its quality meets the standard. Conduct mechanical processing, including processes such as turning, milling, drilling, and grinding. These high-precision processing equipment and processes ensure the dimensional accuracy and shape accuracy of the piston. When necessary, heat treatment and surface treatment are carried out to improve its mechanical properties, wear resistance, surface quality and wear resistance.
Product Application:
Automobile pistons play an important role in automobile components. They bear gas pressure, transmit power, and form the combustion chamber. Piston rings also play the role of scraping oil and distributing oil, maintaining the lubrication and cleanliness of the cylinder wall and piston surface.
