Abstract
The utility model relates to a circulating ball steering device gap adjusting mechanism capable of reducing a mounting size, belonging to the technical field of a car steering device. The circulating ball steering device gap adjusting mechanism capable of reducing the mounting size comprises a side cover, a steering arm shaft, a locking nut, an adjusting bolt and an adjusting hexagon nut, wherein the steering arm shaft is provided with an inner groove and the side cover is symmetrically provided with an outer lug boss; the side cover is inserted into the inner groove mounted on the steering arm shaft through the outer lug boss; the outer groove is internally provided with the adjusting bolt; and the adjusting bolt is in threaded connection with the locking nut. According to the circulating ball steering device gap adjusting mechanism, the outer lug boss of the side cover is mounted into the inner groove of the steering arm shaft and the adjusting hexagon nut is arranged in the outer groove of the side cover, so that the appearance mounting size is reduced. The mounting space is greatly saved; the problem that the existing traditional circulating ball steering device cannot be arranged and mounted when spaces of parts of car chassis are narrower; and the circulating ball steering device gap adjusting mechanism provides great guarantees for the compactness of the design of the chassis.
Description
Technical field
The utility model relates to a kind of ball-and-nut steering gear clearance adjustment mechanism that reduces installation dimension, belongs to the automobile steering device technology field.
Background technology
Along with the develop rapidly of auto trade, the trend that requires to dwindle the chassis part volume is more and more urgent, and is also just imperative as the deflector light-weight design of one of important parts of chassis part.The output torque of unit volume is the key index of weighing deflector, the size of output torque directly has influence on strength at repeated alternation and the operational stability of chaufeur, on the other hand in order to ensure roadability and safety, the present road conditions of combination is constantly perfect simultaneously, its chassis design requires more and more lower, the arrangement structure that is chassis system is more and more compacter, certainly will require thus to reduce the profile installation dimension of deflector in the situation that guarantees the deflector output torque as far as possible.
Traditional ball-and-nut steering gear profile installation dimension is generally 100.5mm, when narrower and small for part car chassis space, can't arrange this type of deflector is installed.Consider simultaneously the trend of automotive light weight technology development, it is compact and can to carry out the ball-and-nut steering gear that interstitial structure adjusts extremely urgent to design a kind of contour structures.
Summary of the invention
The purpose of this utility model is: provide under a kind of prerequisite guaranteeing ball-and-nut steering gear output torque and safe enough and technical performance parameter, by existing ball-and-nut steering gear structural optimization is designed, and then the entrucking Applicable scope of raising ball-and-nut steering gear, reduce the chassis installing space, solve existing traditional ball-and-nut steering gear, when narrower and small for part car chassis space, can't arrange that the ball-and-nut steering gear gap of the reduced installation dimension of installation question is transferred
The complete machine structure.
The utility model is to realize by the following technical solutions above-mentioned purpose:
A kind of ball-and-nut steering gear clearance adjustment mechanism that reduces installation dimension, comprise side cover, steering arm shaft, jam nut, adjust bolt and adjust hexagonal nut, it is characterized in that: be provided with inner groovy on the steering arm shaft, be provided with jam nut in the inner groovy, be symmetrically arranged with outer lug boss on the side cover, side cover inserts by outer lug boss and is installed in the inner groovy of steering arm shaft, outer groove is set on the side cover between the outer lug boss, arrange in the outer groove adjustment bolt is installed, adjust bolt and be threaded with jam nut, the adjustment bolt end in the described outer groove is equipped with the adjustment hexagonal nut.
The utility model advantage compared with prior art is:
The ball-and-nut steering gear clearance adjustment mechanism that this can reduce installation dimension is in the inner groovy by steering arm shaft that the side cover outer lug boss is packed into, and will adjust hexagonal nut and pack in the outer groove of side cover, has reduced thus the profile installation dimension.Be that 100.5mm compares than conventional confguration profile installation dimension, the utility model shortens to 80mm with ball-and-nut steering gear profile installation dimension, has greatly saved installing space, for the compactedness of chassis design provides great guarantee.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of side cover of the present utility model;
Fig. 3 is the structural representation of steering arm shaft of the present utility model.
Among the figure 1, side cover; 2, steering arm shaft; 3, jam nut; 4, adjust bolt; 5, adjust hexagonal nut, 6, inner groovy, 7, outer lug boss, 8, outer groove.
The specific embodiment
The ball-and-nut steering gear clearance adjustment mechanism that this can reduce installation dimension comprises side cover 1, steering arm shaft 2, jam nut 3, adjusts bolt 4 and adjusts hexagonal nut 5.Be provided with inner groovy 6 on the steering arm shaft 2, arrange in the inner groovy 6 jam nut 3 is installed, be symmetrically arranged with outer lug boss 7 on the side cover 1, side cover 1 inserts by outer lug boss 7 and is installed in the inner groovy 6 of steering arm shaft 2, outer groove 8 is set on the side cover 1 between the outer lug boss 7, outer groove 8 interior settings are equipped with adjusts bolt 4, adjusts bolt 4 and is threaded with jam nut 3, and adjustment bolt 4 terminations in the outer groove 8 are equipped with adjusts hexagonal nut 5.
This ball-and-nut steering gear clearance adjustment mechanism that can reduce installation dimension is simple in structure, adjusts bolt 4 and is assemblied between side cover 1 and the steering arm shaft 2, realizes that by adjusting bolt 4 location clamps by jam nut 3 and hexagonal nut 5; And the movement of adjusting bolt 4 axial locations by adjusting by adjustment hexagonal nut 5 realizes the adjustment in ball-and-nut steering gear gap.Simultaneously, this can reduce the ball-and-nut steering gear clearance adjustment mechanism of installation dimension, by in the inner groovy of steering arm shaft 2 that the outer lug boss 7 of side cover 1 is packed into 6, and will adjust hexagonal nut 5 and pack in the outer groove 8 of side cover 1, reduced thus the profile installation dimension, be that 100.5mm compares than conventional confguration profile installation dimension, the utility model shortens to 80mm with ball-and-nut steering gear profile installation dimension, greatly saved installing space, improved the entrucking Applicable scope of ball-and-nut steering gear, avoided existing traditional ball-and-nut steering gear, when narrower and small for part car chassis space, can't arrange the problem of installation, for the compactedness of chassis design provides great guarantee.
