Abstract
The utility model relates to an upper pull rod node used for a motor train unit bogie. The node is installed between an upper pull rod and an axle box; the node comprises a housing, a single layer of rubber and a core axle; the single layer of rubber is sulphidized with the housing and the core axle into an integrated elastic structure; slopes at 15 degrees are arranged at two ends on the outer side of the housing; and the two sides of the single layer of rubber are designed into convex shapes. The node has the advantages of simple and reasonable structure and good flexibility, is installed between the upper pull rod and the axle box, provides flexible supporting for the pull rod and the axle box, has higher fatigue life and softer vertical property, and improves the vibration performance and the comfortableness of vehicles; and the node simultaneously has larger lateral and longitudinal rigidity, and limits the lateral and longitudinal displacement.
Description
Technical field
The utility model relates to a kind of rolling stock Rubber Parts, specifically, relates to a kind of motor train unit bogie truck Rubber Parts.
Background technology
Motor train unit are the present main high speed train of China, and for guaranteeing the operation stability and the stationarity of vehicle, one of motor train unit bogie truck is all to need a large amount of Rubber Parts that adopt with secondary suspension.Wherein, need to provide the Rubber Parts of sinking support between top rod and the axle box for it, still, at present domestic lack a kind of like this for top rod and axle box provide the Rubber Parts of sinking support, to improve vibration of vehicle performance and traveling comfort.
