Abstract
The utility model relates to the steering hardware that a kind of steering hardware having double dynamical deflector, particularly a kind of assist steering force are provided by a kind of hydraulic power steering device.This device comprises the left steering device support of main deflector and the fixing main deflector providing active force, the right steering device support of the secondary deflector helped out and fixed joint deflector, play steering drop arm and the drag link of intermediate transmission effect, connect each right steering joint arm of left steering joint arm and the front steering axle of left and right wheel hub.This steering hardware can not only improve steering hardware stability, improves steering torque simultaneously.This device is applicable to the car of the engineering that weight on front axle is comparatively large, operating mode is poor, front wheel bouncing amount is larger.
Description
Technical field
The utility model relates to the steering hardware of engineering car, specifically a kind of hydraulic power steering apparatus of highway wide dumper.
Background technology
The steering hardware of Traditional project car, add single servo cylinder composition primarily of deflector, servo cylinder two ends act on vehicle frame and track arm respectively.This steering structure; effective steering effort that can provide due to servo cylinder is less; therefore the steering torque that steering hardware provides is less; and when highway operating mode is poor; the shortcoming of the fault such as servo cylinder exists yielding, fracture, leakage of oil, bulb come off, and the hard steering phenomenon that heavily loaded descending steering effort causes not; In addition, the structural arrangement of this servo cylinder, make vehicle suspension degree of convergence of beating comparatively large, servo cylinder stroke variation range increase, interfere increase, suffered hydraulic efficiency impact is comparatively large, cause fault rate higher, the reliability of steering hardware is poor.
Summary of the invention
The purpose of this utility model is, provides a kind of and has larger steering torque, and can fall the new type power steering hardware of end steering hardware fault rate.
the technical solution of the utility model is:
This steering hardware, at least comprises the left steering device support 3 that provides the main deflector 1 of active force and fixing main deflector; The right steering device support 8 of the secondary deflector 9 helped out and fixed joint deflector; Play steering drop arm 2 and the drag link 4 of intermediate transmission effect, connect left steering joint arm 5 and the right steering joint arm 7 of left and right wheel hub, and front steering axle 6.
Main deflector 1, secondary deflector 9 respectively by the fixing fixing left steering device support 3 of main deflector and the right steering device support 8 of fixed joint deflector 9, are fixed on the vehicle frame left and right sides respectively.
Described main deflector 1---provides steering power.Substantially identical with common motive power deflector, there are a high pressure oil inlet, a return opening and two auxiliary hydraulic fluid ports.Main deflector 1 comprises input shaft 10, housing 11, output shaft 12, piston-rack 13 etc., its principle of work is: by the rotation of input shaft 10, the oil-feed of high pressure oil inlet, under the effect of high pressure oil, promote deflector internal piston move up and down, on piston-rack 13 and output shaft 10, the motion of sector connects, again the up-and-down movement of piston is converted to the rotary motion of output shaft 12, steering drop arm 2, then steering drop arm 2 promotes track arm by drag link 4 and realizes turning to of wheel.
Described secondary deflector 9---provides auxiliary force, and secondary deflector only has two oil inlet and outlets, without input shaft.Its principle of work is identical with main deflector, secondary deflector is connected with main deflector two auxiliary hydraulic fluid ports, the hydraulic fluid port oil-feed communicated with main deflector high pressure side, promote secondary deflector piston up-down, piston up-down is changed into the rotary motion of output shaft 10 and steering drop arm 2 by like manner secondary deflector, and then promote right wheel by drag link 4 and turn to, realize assisted diversion effect; Contribute to eliminating the faults such as servo cylinder fracture, bending, leakage of oil, fall end steering hardware fault rate.And the joint arm connected due to secondary deflector 9 lengthens, drag link 4 arm of force is 280mm, is more conducive to realizing light turning to.
This steering hardware can not only improve steering hardware stability, improves steering torque simultaneously.Be applicable to the engineering car that weight on front axle is comparatively large, operating mode is poor, front wheel bouncing amount is larger.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
embodimenta kind of steering hardware of double dynamical deflector
fig. 1, Fig. 2overlooking and main apparent structure of the present embodiment dual rotation device steering hardware respectively; Main deflector 1, secondary deflector 9, be fixed on vehicle frame both sides respectively by left steering device support 3 and right steering device support 8.Major and minor deflector all saves arm 5 and right steering respectively by steering drop arm 2 and drag link 4 and saves arm 7 and be connected with left steering.Secondary deflector 9 has two hydraulic fluid ports, is connected with main deflector 1 liang of auxiliary hydraulic fluid port respectively: when vehicle is turned right, under the effect of main deflector 1 hydraulic power, the steering drop arm 2 be attached thereto is swung backward, promote drag link 4 and revolver is turned right; Simultaneously by from main deflector 1 assists hydraulic fluid port to flow to the effect of the hydraulic oil of secondary deflector 9, make steering drop arm 2 forward rocking motion be connected with secondary deflector 9 promote drag link 4 and make rightly to take turns right-hand rotation, secondary deflector plays assisted diversion effect; Achieve the object that left and right wheels synchronously turns to.In like manner, when vehicle turns left, also can realize left and right wheels and synchronously turn to.
Fig. 3 is the semisectional view of main deflector: structure, the principle of work of main deflector are identical with conventional steering device, by the rotation of input shaft 10, controls the closure or openness of deflector oil inlet; By input shaft 10 cw or rotate counterclockwise, control deflector internal oil passages, to ensure on the right side of piston 13 or left side high pressure (piston moves to the left or to the right); By the cooperation of sector on piston-rack 13 and output shaft 12, piston linear motion is converted to the rotary motion of output shaft 12 ］ and ensure output shaft 12 conter clockwise or clockwise movement, as: when input shaft rotates clockwise, on the right side of piston, high pressure is to left movement, and output shaft is counterclockwise movement.
