Description
Technical field
The utility model belongs to automobile steering device field, particularly relates to a kind of double input end automobile steering device.
Background technology
Deflector to have people to drive with driverless operation and to have the mechanical device of propulsion source, makes its random device changing running route and direction in operational process.Deflector has another name called steering box, steering wheel, and it is most important parts in steering system.Its effect is: increase steering handwheel and pass to the power of steering gear and change the direction of transfer of power.
At present, known hydraulic power steering gear structure mainly comprises ball screw, ball nut and housing, it is input end that ball screw only arranges one end, for closure dish drive member, ball nut is arranged to piston, and housing is arranged to cylinder body, high pressure liquid force feed is as power-assisted medium, drive steering pump to produce by diesel engine or motor, high pressure liquid force feed enters the cylinder body of housing formation by pipeline, and then the piston promoting ball nut formation realizes power steering.Meanwhile, this type of deflector, complex structure, served as when jolting road surface, can there is impact in parts, easily damage deflector under the effect of external force loads, simultaneously the easy contaminated environment of high pressure liquid force feed.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of double input end automobile steering device.
The utility model is taked following technical scheme to realize: a kind of double input end automobile steering device, comprise housing, screw rod and input end, described input end is made up of the first input end and the second input end being arranged on two ends, described second input end is used for closure dish drive member, and described first input end is for connecting motor drive member; Described enclosure interior is pressed close to upper wall and is provided with cylinder, and described cylinder inside is provided with several coil springs of closely arranging; Described first input end and the second input end are connected to screw rod through the bearing hole being arranged on described housing both sides, and described screw rod other end end is provided with pivot shaft; Described cylinder two ends are provided with attaching parts, and the described attaching parts other end is provided with circular arc concave structure; Described circular arc concave structure and described pivot shaft force fit.
Preferably, in described housing, be positioned at described first input end both sides and be provided with O RunddichtringO; In described housing, be positioned at described second input end both sides be provided with O RunddichtringO; Described cylinder and described inner walls are slidably installed; The thickness of described O RunddichtringO is less than the degree of depth of described enclosure interior.
The utility model has following beneficial effect in sum: the utility model improves original diverter structure, by increasing first input end, motor drive member directly inputs power-assisted by first input end, servo steering system can be made to remove steering pump, high pressure liquid force feed and pipeline component, thus make diverter structure simple, and environmental pollution can be reduced; By circular arc concave structure and the described pivot shaft force fit of setting, improve whole deflector input performance; The gap value increased due to rack-and-gear wearing and tearing can be compensated by the coil spring increased, ensure deflector performance; By the O RunddichtringO arranged, effectively reduce deflector noise operationally and collision, increase the service life; Meanwhile, the utility model has wide range of applications, and traveling comfort is high, with low cost, dependable performance, is easy to promote.
accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1, housing; 2, O RunddichtringO; 3, the second input end; 4, cylinder; 5, coil spring; 6, attaching parts; 7, circular arc concave structure; 8, pivot shaft; 9, screw rod; 10, bearing hole; 11, first input end.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of double input end automobile steering device that the utility model provides is described further.
As shown in Figure 1, a kind of double input end automobile steering device, comprise housing 1, screw rod 9 and input end, described input end is made up of the first input end 11 and the second input end 3 being arranged on two ends, described second input end 3 is for closure dish drive member, and described first input end 11 is for connecting motor drive member; Described housing 1 inside is pressed close to upper wall and is provided with cylinder 4, and described first input end 11 and the second input end 3 are connected to screw rod 9 through the bearing hole 10 being arranged on described housing 1 both sides, and described screw rod 9 other end end is provided with pivot shaft 8; Described cylinder 4 two ends are provided with attaching parts 6.
Preferably, described attaching parts 6 other end is provided with circular arc concave structure 7, described circular arc concave structure 7 and described pivot shaft 8 force fit; By circular arc concave structure and the described pivot shaft force fit of setting, improve whole deflector input performance.
Preferably, in described housing 1, be positioned at described first input end 11 both sides be provided with O RunddichtringO 2, in described housing 1, be positioned at described second input end 3 both sides be provided with O RunddichtringO 2; By the O RunddichtringO arranged, thus avoid and served as when jolting road surface, can there is impact in parts, improve the performance of deflector under the effect of external force loads, meanwhile, also effectively reduces deflector noise operationally.
Preferably, described cylinder 4 is slidably installed with described housing 1 inwall.
Described cylinder 4 inside is provided with several coil springs 5 of closely arranging; The gap value increased due to rack-and-gear wearing and tearing can be compensated by the coil spring increased, ensure deflector performance.
Preferably, the thickness of described O RunddichtringO 2 is less than the degree of depth of described housing 1 inside.
The utility model improves original diverter structure, by increasing first input end, motor drive member directly inputs power-assisted by first input end, servo steering system can be made to remove steering pump, high pressure liquid force feed and pipeline component, thus make diverter structure simple, can environmental pollution be reduced again simultaneously.
The above is embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
