Problems solved by technology

The conventional method is to add sealing rings and other devices in the bearing to improve the sealing performance. However, adding sealing rings increases the production process of the bearing on the one hand and increases the cost of manufacturing. On the other hand, the friction torque of the bearing is also large. The sports performance is weakened, and it is difficult to meet the higher technical requirements of the vehicle chassis suspension

Abstract

The invention relates to a plastic sliding bearing, and belongs to the technical field of mechanical structures. The plastic sliding bearing comprises a lower cover plate, an upper cover plate and an annular gasket arranged between the upper cover plate and the lower cover plate. The annular gasket is made of an elastic material and can abut against the upper cover plate and the lower cover plate when being arranged in the annular cavity between the upper cover plate and the lower cover plate, and a good sealing effect is achieved. Furthermore, the upper cover plate and the lower cover plate which are made of elastic materials can further improve the sealing performance, so that a special sealing ring arranged in the bearing is omitted. Therefore, the friction torque of the bearing can be reduced, the dynamic performance of the bearing is improved, and the working requirement of a vehicle suspension system is met. The plastic sliding bearing is simpler and more convenient in manufacturing process, relatively low in production cost and longer in service life.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to the technical field of bearings, in particular to a plastic sliding bearing. Background technique [0002] Sliding bearings are commonly used in the swing position of vehicle chassis suspensions. Due to the special working conditions of the vehicle chassis, the sliding bearing needs to have a certain waterproof and dustproof effect to prolong the life of the product. The conventional way is to add a sealing ring and other devices in the bearing to improve the sealing performance. However, on the one hand, adding a sealing ring increases the production process of the bearing and increases the cost of production and manufacturing. On the other hand, the friction torque of the bearing is relatively large. The sports performance is weakened, and it is difficult to meet the higher technical requirements of the vehicle chassis suspension. [0003] Therefore, how to prov...
