Description
Technical field
The utility model relates to a kind of heavy goods vehicles wheel bolt auxiliary connection.
Background technique
Heavy goods vehicles is a significant components of automobile with the wheel bolt auxiliary connection, and it plays the effect of firm locking wheel, and its performance directly has influence on the Security of vehicle operating, directly has influence on people's life safety.Heavy goods vehicles is to adopt the warm forming machine processing technology with the traditional technology of wheel bolt auxiliary connection, technological process is many, and manufacturing efficiency is low, and each spot size is difficult to guarantee, moreover in machining process, destroyed the streamline tissue of material internal, reduced the mechanical property and the working life of wheel bolt.We adopt cold-heading forming without stock removel technology for this reason, the deficiency before having avoided.
Summary of the invention
For avoiding above drawback, the utility model adopts cold-heading forming without stock removel technology, the deficiency before having avoided.
Heavy goods vehicles is made up of three parts with the wheel bolt auxiliary connection: wheel bolt, locking nut and wheel nut, be provided with a boss in the intermediate portion of wheel bolt, dual-side at boss is equipped with supporting surface, the two ends of wheel bolt are equipped with outside thread, wheel nut all is connected with the outside thread at wheel bolt two ends with locking nut, and the two ends of described boss are provided with pulls mouth.
Heavy goods vehicles adopts cold-heading forming without stock removel technology with the wheel bolt auxiliary connection, each position external dimension, geometrical shape and surface quality have better been guaranteed, better guarantee its inner flow-line tissue, improved mechanical property, physical property, assembly performance and the working life of wheel bolt; Owing to adopt no cutting, reduced labor intensity, improved manufacturing efficiency greatly, reduced cost of production.The special construction of wheel bolt, locking nut and wheel nut has guaranteed assembly performance and locking property, has guaranteed the Security of vehicle operating.
The heavy goods vehicles characteristics of wheel bolt auxiliary connection:
1, material adopts the high-quality steel
2, the structure of surface configuration counterpart has guaranteed that assembling is rotated flexibly and locking property is good.
3, special structure and the every performance index Security that guaranteed vehicle operating.
