Description
Technical field
The present invention relates to automotive field, specifically a kind of steeraxle of Obtaining Accurate steering angle.
Background technology
The automobile of current common rear-axle drive on automotive market, its front steering axle mainly comprises the parts such as axis body, steering swivel, mostly axis body is forging molding, axis structure is I-shaped solid beam commonly, generally on H-girder axis body, suspension is installed, thus the upper table plane of H-girder slightly wider than the upper table plane at following table plane or some position middle wider than following table plane, to make the installation support platform of suspension enough roomy.At the visible a pair tubular bearing in two ends of front steering axle, be obtain, the in-built steering yoke bolt in hole at two ends bore hole after axis body forging, this bearing connects in order to pivotable between steering swivel with axis body.The tooling cost of the I-shaped solid beam propons of this solid forging is comparatively large, and number of molds and expense are all very high, and commonality is not strong; The front steering axle of usual forging processing prepares production from frock, and the duration is all very long, and correspondingly time of delivery is also very long; On the other hand, in use easily there is deformation because rigidity is not enough in this propons, causes unnecessary wear on tyres.And when Vehicular turn operates, rotate bearing circle, steering swivel will be driven to rotate together with steered wheel, but during due to rotating of steering wheel, accurately cannot obtain the deflection angle of wheel, especially for the vehicle of many steeraxles, the synchro control turned to is a hang-up.
Summary of the invention
The object of the present invention is to provide that a kind of safety factor is high, the steering axle of automobile of Obtaining Accurate steering angle, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of steering axle of automobile, comprise transmission shaft and steering swivel, transmission shaft connects steering swivel by attaching parts, transmission shaft comprises axle head, armshaft and axle core, axle head, armshaft and axle core are hollow central siphon, armshaft connects axle head and axle core at a certain angle, makes the axle core of axle head and level have the pipeline section of smooth connection; Axle head offers through hole, and steering swivel is installed perpendicular to axle head, and runs through the through hole of axle head, and the axial line of through hole departs from midperpendicalar certain angle; Be fixed on the pin shaft hole end face of steering swivel termination by rotary angle transmitter by bolt of rear end plate, the fixed central spindle of rotary angle transmitter inserts in the pin shaft hole of steering swivel termination, and the fixed central spindle of rotary angle transmitter is connected with bearing pin key.
As the further scheme of the present invention: the cross section of axle head and axle core is rectangle, the cross section of armshaft is circular or sub-circular.
As the further scheme of the present invention: the shape of through hole is tubular or wedge shape.
As the further scheme of the present invention: the top of rotary angle transmitter arranges seal closure, rotary angle transmitter and pin shaft hole end face install cushion rubber bumper.
Compared with prior art, the invention has the beneficial effects as follows: transmission shaft processing tool of the present invention drops into and can greatly reduce, and does not need to be welded to connect, enhance the safety of transmission shaft between axle head, armshaft, axle core; Axle core is square-section, make transmission shaft have better rigid design, on steering swivel, arrange rotary angle transmitter, structure is simple simultaneously, the angular displacement information of steeraxle directly, is quickly and accurately obtained, thus obtains the angular transposition synchronically controlling information of multi-axle steering.

In figure: 1-axle head, 2-armshaft, 3-axle core, 5-through hole, 6-bearing pin, 7-seal closure, 8-cushion rubber bumper, 9-bolt of rear end plate, 10-rotary angle transmitter.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In the embodiment of the present invention, a kind of steering axle of automobile, comprise transmission shaft and steering swivel, transmission shaft connects steering swivel by attaching parts, transmission shaft is made up of axle head 1, armshaft 2 and axle core 3, axle head 1, armshaft 2 and axle core 3 are hollow central siphon, and the erecting stage of suspension is in the region of axle core 3.Armshaft 2 connects axle head 1 and axle core 3 at a certain angle, makes axle head 1 have the pipeline section of smooth connection with the axle core 3 of level.Transmission shaft is hollow structure, and wherein axle head 1 and axle core 3 are square-section, and armshaft 2 is round section or near round cross-section.Axle head 1 offers through hole 5, steering swivel is installed perpendicular to axle head 1, and runs through the through hole 5 of axle head 1, and the axial line of through hole 5 departs from midperpendicalar certain angle.Through hole 5 can be tubular or wedge shape, and the bearing pin 6 of steering swivel or steering pivot or other pivotable connector insert in through hole 5.
Rotary angle transmitter 10 is fixed on bearing pin 6 hole end surface of steering swivel termination by bolt of rear end plate 9; and rotate together along with steering swivel; the top of rotary angle transmitter 10 arranges seal closure 7; rotary angle transmitter 10 and bearing pin 6 hole end surface install cushion rubber bumper 8; avoid delivering sensor 10 and be subject to external interference; also play the effect that sensor 10 is delivered in protection simultaneously, increase the service life.The fixed central spindle of rotary angle transmitter 10 inserts in bearing pin 6 hole of steering swivel termination, and the fixed central spindle of rotary angle transmitter 10 is connected with key with bearing pin 6, and therefore the angular displacement information of rotary angle transmitter 10 exports the angular displacement information directly reflecting steering swivel and wheel flutter.For the vehicle of many steeraxles, steering hardware as each steeraxle all arranges a rotary angle transmitter 10, just can measure the deflection angle of each steeraxle, output to control mechanism after take off data being input to disposal system process, just can realize turning to synchro control accurately.
Transmission shaft processing tool of the present invention drops into and can greatly reduce, and does not need to be welded to connect, enhance the safety of transmission shaft between axle head 1, armshaft 2, axle core 3; Axle core 3 is square-section, make transmission shaft have better rigid design, on steering swivel, arrange rotary angle transmitter 10, structure is simple simultaneously, the angular displacement information of steeraxle directly, is quickly and accurately obtained, thus obtains the angular transposition synchronically controlling information of multi-axle steering.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
