Abstract
The invention discloses a vehicle steering column, which comprises a steering column, wherein the steering column consists of an upper shaft and a lower shaft. The upper shaft and the lower shaft are connected by a variable-rigidity torsion bar; the inner circle of the upper shaft has internal teeth, the outer circle of the lower shaft has external teeth matched with the internal teeth of the upper shaft; and when a steering wheel is centered, the internal teeth of the upper shaft are position in gaps between the adjacent external teeth of the lower shaft for connection. The steering wheel is rotated, and when the internal teeth and the external teeth contact completely, the range of the single edge rotation angle of the upper shaft from the centered position of the steel wheel is set between 6 and 10 DEG. When the steering wheel is rotated within a certain angle range, the steering force applied on the steering wheel increases with the increase in a steering angle, so an excellent steering feel is provided. Thus, it is easier for the steering wheel to return to and stay in a central position, the straight driving feel of a driver is enhanced, and driving fatigue of the driver is relieved.
Description
Technical field
The present invention relates to the wheel steering system field, especially relate to a kind of steering column for vehicle.
Background technology
Present for motor vehicle Steering gear product, the characteristics that on version, most torsional stiffnesies is steady state value, can not change, the power that acts in whole steering procedure on the bearing circle all is invariable.But in the actual use of vehicle, when chaufeur carries out steering operation, wish that the hand-power that is applied to bearing circle changes and changes along with angle.If steering effort can increase gradually along with the increase of steering angle, is a kind of extraordinary sensation that turns to.Simultaneously,, be convenient to the subjective sensation and the judgement of chaufeur, thereby reduce the degree of fatigue in the driving process if bearing circle can remain on midway location as far as possible.Specifically, make exactly that the bearing circle of vehicle is easier gets back to and remain on midway location, strengthen the straight-line travelling sensation of chaufeur, reduce tired.Particularly highly beneficial to driving under the situation that express highway travels for a long time.And above-mentioned requirement, the Steering gear product of conventional structure can't be realized.
Summary of the invention
The purpose of this invention is to provide a kind of steering column for vehicle, solve the common vehicle Steering gear and can not realize that the steering effort that acts in the steering procedure on the bearing circle increases along with the increase of steering angle, can not make the easier problem of getting back to and remaining on midway location of bearing circle.
The technical solution adopted for the present invention to solve the technical problems is: a kind of steering column for vehicle comprises Steering gear; Described Steering gear is divided into axle and two sections of lower shafts, described go up spool and lower shaft between torque rod joint by variable rigidity; Offer internal tooth on the interior circle of described upward axle, the cylindrical of lower shaft is provided with the corresponding external tooth of internal tooth with last axle; During bearing circle centering, the internal tooth of last axle places the adjacent external tooth midway location gap of lower shaft to connect.
In the present invention, when steering wheel rotation, described internal tooth contacted fully with external tooth, last axle was set in the 6-10 degree from the monolateral rotational angle range in bearing circle centering position.
The left end of described torsion bar adopts interference fit to be connected with last axle; The right-hand member of described torsion bar adopts pin to captive joint with lower shaft.
The described upward internal tooth of axle and the external tooth of lower shaft are 6.
In order to prevent that dust from entering, described junction of going up axle and lower shaft is provided with guard shield.
Beneficial effect of the present invention: because Steering gear is divided into axle and two sections of lower shafts, by the torque rod joint of variable rigidity, last internal tooth places the adjacent external tooth midway location gap connection of lower shaft between last and the lower shaft.Steering wheel rotation is in the certain angle scope, and the steering effort on the action direction dish increases along with the increase of steering angle, and a kind of extraordinary sensation that turns to is provided.Make that bearing circle is easier gets back to and remain on midway location, strengthen the straight-line travelling sensation of chaufeur, reduce driving fatigue.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.

Among the figure: 1. axial columns, 2. the bearing circle coupling end, 3. go up axle, 31. internal tooths, 4. lower shaft, 41. external tooths, 5. torsion bar, 6. pin, 7. guard shield.
The specific embodiment
Embodiment 1, shown in Fig. 1 to 5, and a kind of steering column for vehicle, comprise Steering gear 1, the upper end of Steering gear is connected with the bearing circle rotating shaft by universal-joint, and the other end of bearing circle rotating shaft is a bearing circle coupling end 2, and the Steering gear lower end also is connected with turning to actuating unit by universal-joint.Described Steering gear is divided into axle 3 and 4 two sections of lower shafts, the described torsion bar 5 that passes through variable rigidity between axle and the lower shaft of going up connects, the left end of described torsion bar 5 adopts interference fit to be connected with last axle 3, and the right-hand member of described torsion bar 5 adopts pin 6 to captive joint with lower shaft 4.Offer internal tooth 31 on the interior circle of described upward axle 3, the cylindrical of lower shaft 4 is provided with the internal tooth 31 corresponding external tooths 41 with last axle; During bearing circle centering, the internal tooth 31 of last axle places the adjacent external tooth 41 midway location gaps of lower shaft to connect.The described upward internal tooth 31 of axle and the external tooth 41 of lower shaft are 6.
In order to prevent that dust from entering, described junction of going up axle and lower shaft is provided with guard shield 7.
When steering wheel rotation, described internal tooth contacted fully with external tooth, last axle was set in the 6-10 degree from the scope of the monolateral rotational angle A in bearing circle centering position.
Principle of work of the present invention is, in the steering operation incipient stage, utilizes the elastic deformation of torsion bar in the stiffness changing structure to transmit steering effort fully, and this moment, steering effort was less relatively, and line style increases along with the increase of corner input; When turning to input force to increase to a certain degree, last axle and lower shaft relatively rotate angle when being A, and last the internal tooth and the external tooth of lower shaft contact fully, and Steering gear becomes through-coupling, and rigidity no longer changes at this moment, and steering effort is constant; After steering operation was finished, chaufeur unclamped bearing circle, and this moment, torsion bar recovered distortion beginning resilience, and then bearing circle can be got back to midway location sooner.
Among the present invention, steering wheel rotation is in the certain angle scope, and the steering effort on the action direction dish increases along with the increase of steering angle, and a kind of extraordinary sensation that turns to is provided.Bearing circle is easier gets back to and remains on midway location, strengthens the straight-line travelling sensation, the particularly situation of travelling for a long time at express highway of chaufeur, reduces driving fatigue.
