Abstract
The utility model belongs to the technical field of steering gears, and provides a cycle ball rocking arm type power steering gear box which comprises a hollow shell. Assembly connecting holes are reserved on the upper surface of the shell. A piston assembly hole is reserved at one end of shell. More than two cylinder barrel cover connecting holes are reserved at the outer edge of the piston assembly hole. A steering shaft assembly hole is reserved at the other end of the shell. A hydraulic control oil port is reserved on the outer side of the steering shaft assembly hole. A sector gear shaft assembly hole is reserved at the lower end of the shell and in the direction perpendicular to that of piston mounting of the shell, is a hollow cylindrical cavity, and is perpendicular to the shell and communicated with an inner cavity. A power-assisted steering system is arranged on the box, so that a whole cycle ball rocking arm type power steering system is compact in structure, less in overall space occupation and stable in performance, and automobile control stability is improved effectively.
Description
Technical field
The utility model relates to the steering box technical field, is specifically related to a kind of hydraulic power-assisted steering box body.
Background technology
Deflector has another name called steering box, direction machine, it be turn to be in most important parts.Its effect is: increase the direction of transfer that steering handwheel passes to the power of steering gear and changes power.Deflector can be divided into polytype by version, and have pinion and-rack, worm screw crank stylus pin formula, circulation ball-rack tooth commonly used are at present fanned formula, circulation ball crank stylus pin formula, worm screw roller type etc.
The ball-and-nut steering device is will to be slowed down from the rotational force of steering handwheel by gear mechanism, make rotatablely moving of steering handwheel become rotatablely moving of turbine and worm, ball screw and nut clip the steel ball engagement, thereby rotatablely moving of ball screw becomes straight-line motion, nut meshes with quadrant gear again, straight-line motion becomes again and rotatablely moves, pitman arm is shaken, pitman arm makes interlock pull bar and intermediate rod do straight-line motion again, change the direction of wheel, compare rack and pinion steering gear, ball-and-worm steering system is because more dependence friction of rollings, so have higher driving efficiency, handle lighter comfortable, the wearing and tearing of mechanical part are less, service life is longer relatively, in the period that does not have power steering, ball-and-worm steering system has occupied dominant position, but, along with the power steering broad application, rack and pinion steering gear is caught up from behind very soon, thereby be more conducive to install work-saving device because its structure is simpler, in addition, compare with ball-and-worm steering system, turning to of rack and pinion steering gear is more direct, feed back also sensitiveer, this emphasize on the sports style manned vehicle of road feel more welcome, in the middle of small-sized manned vehicle, because ball-and-worm steering system is comparatively outmoded, the use of ball-and-worm steering system is fewer and feweri, how it is had higher driving efficiency, handle light comfortable, advantages such as the wearing and tearing of mechanical part are less, and service life is relatively long with nowadays the power steering technology combines, make ball-and-worm steering system become operation stabilization, the part of the automobile steering system of high security is that the automobile steering device technical field is endeavoured the problem that solves for many years.
The utility model content
The purpose of this utility model is to provide a kind of circulation ball rocker-arm power steering box body, by servo steering system is installed on this casing, it is few to make whole circulation ball rocker-arm power steering system compact conformation, integral body take up space, and stable performance effectively promotes automobile and controls stability.
The purpose of this utility model is realized by following technical proposals: a kind of circulation ball rocker-arm power steering box body, the hollow housing 1 that comprises the piston that installation is connected with the worm steering shaft by steel ball, housing 1 upper surface is provided with assembling connecting bore 2, end at described housing 1 is provided with piston assembly opening 3, the outer of piston assembly opening 3 offers two above cylinder barrel lid connecting bores 4, the other end of described housing 1 is provided with steering shaft assembly opening 5, the outside of steering shaft assembly opening 5 offers hydraulic control hydraulic fluid port 6, lower end at described housing 1, offer sector axle assembly opening 7 on the direction perpendicular to housing 1 installation piston, described sector axle assembly opening 7 is a hollow cylindrical cavity, and with described housing 1 perpendicular and intracavity inter-connection.
Described sector axle assembly opening 7 is one-body molded with housing 1.
The number of described cylinder barrel lid connecting bore 4 is 6.
In actual applications, described housing 1 and piston are formed an oil cylinder, piston is converted to straight-line motion with rotatablely moving of steering shaft, make the rotation of rocking arm sector shaft simultaneously, by steel ball, piston and worm steering shaft corresponding sports, when the rotation of worm steering shaft, steel ball enters its worm screw face successively, and by circulating pipe, steel ball can move in circles on the worm steering shaft.
The utility model is simple in structure, easy for installation, compact conformation is conducive to improve the stability of controlling of steering swivel system, compare with the steering box of fixed speed ratio, near the speed ratio of the steering box of variable-speed ratio meta is less, guarantees the sensitivity that turn to this moment, when the parking wide-angle turns to, the speed ratio of steering box is bigger, can make the rocking arm sector shaft obtain bigger hydraulic booster, when hydraulic booster lost efficacy, the power of beating direction was little than the steering box of fixed speed ratio.
