Abstract

The invention provides an air spring upper cover, an air spring, an air spring upper cover test tool and an air spring upper cover manufacturing method. The air spring upper cover comprises a cover plate and two stopping parts, wherein the two stopping parts are fixedly connected onto the same board surface of the cover plate; the two stopping parts are distributed at an interval so as to enable the air spring upper cover to be U-shaped, and the two stopping parts can limit the transversal displacement of an air spring air bag along a vehicle from the two sides of the air spring air bag. According to the air spring upper cover, the air spring, the air spring upper cover test tool and the air spring upper cover manufacturing method, a vehicle can meet the requirement of a smaller gyroscopicmoment during the curve driving process and the requirement of little transversal shaking.

Description

technical field [0001] The invention belongs to the technical field of vehicle vibration reduction, and in particular relates to an empty spring upper cover, an empty spring and an empty spring upper cover test tool and a manufacturing method thereof. Background technique [0002] Air springs (i.e. air springs) are widely used in commercial vehicles, buses, rail vehicles and other equipment due to their advantages of small mass and long life. When the vehicle passes through the curved track at a high speed, in order to generate a small turning moment and small lateral shaking, the air spring needs to have a small longitudinal stiffness and a large lateral stiffness. [0003] The structure of the existing air spring (such as the upper cover) is mostly arranged symmetrically along each direction, so that the air spring has basically the same stiffness performance in each horizontal direction. However, in the process of adjusting the stiffness of the existing air spring, adjus...
