Through a hydraulic electrical control system, the invention combines the force of height setting and collision energy absorption of a steering wheel organically, and can satisfy the need of comfortable driving and safety, moreover, a wheel pump of a power source and a valve are arranged separately from the steering pipe column, facilitating rational use of the inner space of a vehicle body.
Description
Technical field
The present invention relates to the steering column in the automobile steering system.
Background technology
Steering column is the important component part in the automobile steering system.The design of steering column must be satisfied the handling comfort and the safety of chaufeur.Therefore; now the steering column of car basically can up-down adjustment, satisfying different chaufeurs steering dish easily, and steering column can be moved down or fracture automatically; realize the absorption of collision energy, with the protection driver safety.
The adjusting of steering tubular column of car is to have different structures to guarantee with energy-absorbing at present, and wherein regulative mode has two kinds, and a kind of is to realize by pure physical construction, and another kind is to realize by the driven by motor leading screw.The former structure complexity is unfavorable for arranging on car load, the latter mainly be cost than higher, and the quality of motor is also bigger, size is also not little.And steering column energy-absorbing device, major part is to realize by shearing the friction force of going up hypomere after plastic pin and tubing string disconnect, can not guarantee that transition of energy-absorbing curve smoothing and energy-absorbing are even.
Summary of the invention
The purpose of this invention is to provide a kind of later-model steering column, it realizes the effect of the height adjustment and the collision energy-absorbing of bearing circle by the hydraulic electric control system, can also reduce the effect of vibrations noise, thereby reaches the effect of not only saving space but also cost-cutting.
The objective of the invention is to be achieved through the following technical solutions:
A kind of automobile steering tubular column unit, comprise a hydraulic gear, this hydraulic gear comprises a hydraulic ram and a pitch brace that is plugged in this hydraulic ram, and by pass valve that is connected by pipeline with this hydraulic ram and the sensor that is electrically connected with this by pass valve.
Wherein, this hydraulic gear also contains an oil supply mechanism, the electric gear wheel pump that comprises the three-position four-way valve that is connected by pipeline with this hydraulic ram, is connected by pipeline with this three-position four-way valve.
The closed end of described hydraulic ram links to each other with a universal-joint, and an end of described pitch brace links to each other with vehicle steering.
This device also is provided with a height stop gear, comprises one first groove, is located on the block of open end inboard of hydraulic ram, also comprises second groove that is located on this pitch brace, wherein is provided with at least one spring, is connected with spacing bead on this spring.
Wherein, this block is captiveed joint with this hydraulic ram, or one-body molded with this hydraulic ram.
In addition, this device also is provided with a rotary stopper mechanism, comprise a boss that is located at this hydraulic ram outer wall, which is provided with a boss hole, the axis in hole is consistent with the axis direction of hydraulic ram and pitch brace, also comprise a slide bar that is plugged in this boss hole, this slide bar links to each other with this pitch brace by a base.Described base is captiveed joint with this pitch brace or is one-body molded.In this boss hole, be provided with rubber bush.
Positive progressive effect of the present invention is: by the hydraulic electric control system height adjustment of bearing circle and the effect of collision energy-absorbing are organically combined, can satisfy the effect that traveling comfort is driven, can satisfy safe requirement again, in addition that propulsion source gear type pump and valve body and steering column is arranged apart, help the reasonable utilization in interior of body space.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of height stop gear among the embodiment.
Fig. 3 is the structural representation of rotary stopper mechanism among the embodiment.
The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.As shown in Figure 1, change steering column into hydraulic gear among the present invention, comprise a hydraulic ram 2 and the piston tube column 6 that is plugged in wherein.The closed end of hydraulic ram 2 is connected with universal-joint 1, conveniently links to each other with other parts of steering swivel system.One end of piston tube column 6 plays piston, and the other end is the same with traditional tubing string, with spline bearing circle 12 is coupled together with it.
And, by pass valve 8 that is connected by pipeline with this hydraulic ram 2 and the sensor 7 that is electrically connected with this by pass valve 8.
By pass valve 8 is in normally off always, when collision happens, after sensor 7 detects the impact force signal, signal is passed to by pass valve 8.When impact force surpassed the pressure of by pass valve 8 settings, by pass valve 8 was opened, and the power fluid of hydraulic ram flows to hydraulic pressure oil can 10, piston tube column 6 and bearing circle 12 mounted thereto descend, vacating space, actv. guarantees the safety of chaufeur, plays the effect of collision energy-absorbing.
Hydraulic gear also comprises oil supply mechanism, is used for to hydraulic gear supply power fluid, the electric gear wheel pump 11 that comprises the three-position four-way valve 9 that is connected by pipeline with this hydraulic ram 2, is connected by pipeline with this three-position four-way valve 9.Power fluid is stored in the hydraulic pressure oil can 10, and oil can 10 links to each other with this by pass valve 8 with this three-position four-way valve 9 by pipeline.
When filling operation is oily in hydraulic ram 2 by oil supply mechanism, bearing circle is risen, otherwise, bearing circle is descended.Can button be set on bearing circle operates.
The open end of hydraulic ram 2 is provided with block 21, comes off to prevent pitch brace 6, and this block 21 is captiveed joint with this hydraulic ram 2, or one-body molded with this hydraulic ram 2.
Because hydraulic pressure transfer can the absorption portion energy,, be provided with the height stop gear in hydraulic pressure tubing string height adjustment direction, as shown in Figure 2 for fear of because of 2 link stopper 21 direct contacts in piston tube column 6 and the hydraulic actuating cylinder produce noise.
This height stop gear comprises one first groove 5, be located on the block 21 of open end inboard of hydraulic ram 2, and be located at second groove 61 on this pitch brace 6, wherein be provided with at least one spring 62, on this spring 62, be connected with spacing bead 3, spring 62 1 ends and piston tube column 6 are fixed together, and the other end and spacing bead 3 link together.When transferring to constrain height on the piston tube column, spacing bead 3 slides in first groove 5, plays spacing effect.Still exist spatial volume between piston tube column 6 and the link stopper 21 this moment, thus the effect of playing the energy-absorbing damping and reducing noise.
Because need the steering wheel rotation that do not stop in the vehicle traveling process, rotate with respect to hydraulic ram 2 in order to prevent piston tube column 6, thereby cause chaufeur to lose road feel, on this device, also be provided with rotary stopper mechanism.
As shown in Figure 3, this rotary stopper mechanism, comprise a boss 4 that is located at these hydraulic ram 2 outer walls, which is provided with a boss hole 4a, the axis in hole is consistent with the axis direction of hydraulic ram 2 and pitch brace 6, also comprise a slide bar 4b who is plugged among this boss hole 4a, this slide bar 4b links to each other with this pitch brace 6 by a base 4d, and base 4d is captiveed joint with this pitch brace 6 or be one-body molded.In order to reduce the wearing and tearing of boss hole 4a and slide bar 4c, one deck rubber bush 4b is installed in this boss hole 4a in addition.
