Abstract
The utility model discloses a hydraulic power assisted integral automobile power steering gear which is high in output torque, simple in structure and stable and reliable in performance. The hydraulic power assisted integral automobile power steering gear comprises a housing. An inner cavity of the housing is divided into an upper cavity and a lower cavity. The housing is provided with a bonnet on one side of the upper cavity. An inner cavity of the bonnet is provided with a valve sleeve screw through a bearing. An input spool shaft is movably disposed in an inner cavity of the valve sleeve screw and the input spool shaft is connected with the piston through a tension bar. A return oil passage is formed among the lower cavity, the valve sleeve screw and the upper cavity. The piston is movably connected with a steering mechanism through a gear-rack pair. The piston, the valve sleeve screw, the input spool shaft and the torsion bar are coaxial.
Description
Technical field
The present invention relates to auto parts and components, be specifically related to a kind of hydraulic booster monolithic devices automobile power steering.
Background technology
Hydraulic booster monolithic devices automobile power steering can be converted into pressure energy by the part mechanical energy of driving engine (or motor) output, and under chaufeur is controlled, a certain Transmission in steering transmission linkage or deflector is applied to the hydraulic action of different directions, to save chaufeur muscle power, improve the automobile handling.Existing hydraulic booster car load type automobile power steering complex structure, parts are many, thereby its precision is subject to the impact of assembling level and parts manufacture level larger, and quality is not allowed controlled.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of hydraulic booster monolithic devices automobile power steering, and its output torque is high, simple in structure, stable and reliable for performance.
For achieving the above object, hydraulic booster monolithic devices automobile power steering of the present utility model, comprise housing, and the housing inner chamber is divided into epicoele and cavity of resorption by piston; Be provided with valve gap on the housing of described epicoele one side, the valve gap inner chamber is provided with the valve pocket screw rod through bearing, valve pocket screw rod inner chamber is movably set with the transfer valve mandrel, the transfer valve mandrel is connected with piston through torsion bar, be provided with drainback passage between cavity of resorption, valve pocket screw rod, epicoele, piston is flexibly connected through rack-and-pinion and steering hardware; Described piston, valve pocket screw rod, transfer valve mandrel, torsion bar coaxially arrange.
In said structure, the parts of use are less, simple in structure, need the critical size of controlling to reduce accordingly, reduced the assembly precision requirement, and the factor that affects hand force property and valve return is less, thereby performance is stable and reliable for performance.Be connected with piston and adopted non-penetration type structure due to torsion bar, increased the area of thrust surface of piston, improved output torque.
The accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic booster monolithic devices automobile power steering of the present utility model.
In Fig. 1: 1---housing; 2---piston; 3---bearing; 4---the valve pocket screw rod; 5---valve gap; 6---the transfer valve mandrel; 7---torsion bar; 8---drainback passage; 9---steering hardware; 10---epicoele; 11---cavity of resorption; 21---rack-and-pinion.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, hydraulic booster monolithic devices automobile power steering of the present utility model, comprise housing 1, and housing 1 inner chamber is divided into epicoele 10 and cavity of resorption 11 by piston 2; Be provided with valve gap 5 on the housing 1 of described epicoele 10 1 sides, valve gap 5 inner chambers are provided with valve pocket screw rod 4 through bearing 3, the outer ring of bearing 3 is the two-opening type structure, valve pocket screw rod 4 inner chambers are movably set with transfer valve mandrel 6, transfer valve mandrel 6 is connected with piston 2 through torsion bar 7, be provided with drainback passage 8 between cavity of resorption 11, valve pocket screw rod 4, epicoele 10, piston 2 is flexibly connected through rack-and-pinion 21 and steering hardware 9; Described piston 2, valve pocket screw rod 4, transfer valve mandrel 6, torsion bar 7 coaxially arrange.
Principle of work of the present utility model: by the rotating of steering wheel left or right, thereby drive torsion bar 7 twistings elastic deformation occurs, make between transfer valve mandrel 6 and valve pocket screw rod 4 to rotate angle ± 7 °, high pressure oil enters epicoele 10, while entering epicoele 10, promote piston 2 toward the cavity of resorption motion, at this moment valve pocket screw rod 4 produces rotation, and cavity of resorption 11 oil are discharged by drainback passage 8.Otherwise high pressure oil enters cavity of resorption 11, promote piston 2 toward epicoele 10 motions, the interior oil of epicoele 10 is discharged by drainback passage 8.Piston 2 drives the steering hardware motion.
In said structure, the factor that affects the valve return mainly contains: 1, the right alignment between transfer valve mandrel 6 and torsion bar 7; 2, torsion bar 7 and turn to the right alignment between valve pocket screw rod 4 afterbody places; 3, right alignment and the tolerance clearance of the endoporus of the cylindrical of transfer valve mandrel 6 and valve pocket screw rod 4.Compared with prior art, influence factor greatly reduces, thereby is easy to improve precision.
Hydraulic booster monolithic devices automobile power steering of the present utility model, be non-penetration type connection structure between torsion bar 7 and piston 2, increased the area of thrust surface of piston 2, improved output torque.
Hydraulic booster monolithic devices automobile power steering of the present utility model, also applicable to the steering inner articulated shaft with the double jaw joint fork.
Said structure passes through loading stress and proves, its return better performances, easily reach the hand force property curve requirement be complementary with client's vehicle, and this structure makes the part centralized arrangement, and assembly process reduces, and has reduced manufacturing cost; Simultaneously required controlling dimension reduces, precision easily guarantees.
