Sliding and crushing integrated steering column and automobile

Abstract

The invention discloses a sliding and crushing integrated steering column and an automobile, the sliding and crushing integrated steering column comprises an inner tube, an outer tube, an outer tube, an outer tube, an inner tube roller path groove and an inner tube roller path groove, the outer periphery of the inner tube is provided with an inner tube roller path groove, and the groove wall of the inner tube roller path groove is provided with a convex part; an outer pipe raceway groove is formed in the inner circumference of the outer pipe, and the outer pipe raceway groove can be matched with the inner pipe raceway groove to form a containing cavity; the roller pin is movably arranged in the accommodating cavity, and the roller pin interferes with the lug boss and can crush the lug boss when the thrust applied to the roller pin reaches a set value; according to the steering tubular column, sliding fit between the inner tubular column and the outer tubular column is optimized through the arrangement of the roller pins, the operation hand feeling is improved, the sliding and crushing integrated design is achieved through the cooperation of the protruding parts arranged on the groove walls of the inner tube roller path grooves and the roller pins, and the energy absorption effect and the safety of an automobile are improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a sliding and crushing integrated steering column and an automobile. Background technique [0002] With the application of new technologies, there are more and more functions on the car, and the integration of functions is imperative. [0003] As an important part of the steering system, the steering column has many functions, and each structure is designed and developed based on the functions that need to be satisfied. Among them, the adjustment force of the column that affects the operating comfort of customers and the crushing characteristics of the column that affect the safety of collisions are both Important functions of the string. The coordination of the inner and outer tubes has a great influence on the axial adjustment force during axial adjustment, but the current design is that the inner and outer tubes are basically disengaged, and the matching s...

AI Technical Summary

Problems solved by technology

When adjusting the existing pipe string, first loosen the handle, the inner and outer pipes of the pipe string are disengaged, and the outer pipe fits the mounting bracket. Due to the uneven cooperation between the inner and outer pipes of the pipe string, the outer pipe of the pipe string and the bracket, the handle feels when the pipe string is adjusted Unsmooth; the column crushing energy-absorbing structure mainly provides the peak force for injection molding, and due to the influence of the injection molding process, the crushing force control tolerance is relatively large
