After could process, be consequently belonging to on-line machining, its complex process, work step number is more, requires high to personnel and plant maintenance, processes
The residual of iron filings and burr can not be avoided completely afterwards, easily leave hidden danger of quality.
The content of the invention
For above technical problem, present invention offer one kind is simple in construction, easy to assembly reliably, cost is low, packaging efficiency
The New-type EPS spindle mounted structure of raising.
The present invention is that technical scheme is used by solving its technical problem：
A kind of new automobile electric power-assisted steering apparatus spindle mounted structure, is applied in electric power-assisted steering apparatus reductor
In structure, including input shaft, output shaft and the torsion bar being connected between input shaft and output shaft, input shaft and output shaft are set respectively
There is the endoporus that two shaft ends for torsion bar are inserted, two shaft ends of the torsion bar are respectively equipped with vertical with central shaft and are in same
The opening position that positioning hole is corresponded in the endoporus side wall of the positioning hole of one plane, input shaft and output shaft is respectively equipped with jack, described
Two shaft ends of torsion bar are inserted into the endoporus of input shaft and output shaft in a manner of quantitative gap coordinates respectively, corresponding positioning
Hole and receptacle alignment form the axis hole of insertion, and alignment pin is pressed with a manner of quantitative interference fit in axis hole.
As preferred embodiment, the front end of the input shaft is inserted into the endoporus of the output shaft, output shaft
Oilless bushing is provided between endoporus and the front end of input shaft.
As preferred embodiment, the oilless bushing is pressed the endoporus in output shaft in a manner of quantitative interference fit
Interior, the front end of the input shaft assembles in a manner of quantitative gap coordinates with oilless bushing.
Its advantage of the invention compared with existing automobile electric power steering (EPS) device EPS spindle mounted structures is as follows：
1st, interchangeability is good when torsion bar both ends assemble, and assembling mechanism is convenient and reliable；During press fitting, torsion bar is not in any form
Flexural deformation, without detect again assembling after whether can deform, prevent assembling when occur sensor angles deviation etc. influence
The potential failure problem of assembly function, while there is invertibity, dismounting is reproducible；
2nd, the positioning of press fitting two finger settings are convenient, disposably locating clip can press and fill two alignment pins, without Special Automatic centering
Pin pressing machine is punched to complete, cost is reduced, improves packaging efficiency；
3rd, the distance between each positioning hole of input shaft, output shaft, torsion bar can ensure that the axial direction between torque sensor and rotor
Distance will not change, and assembling process is simple and convenient；
4th, mechanical centering need not be carried out after input shaft, output shaft, torsion bar assembling, it is each fixed by torsion bar, input shaft, output shaft
Position hole machined precision controlling, the higher transducer of cost free, parts assembly manipulation is simple, improve production efficiency, reduce compared with
Big production cost.
Brief description of the drawings
It is further detailed with reference to the accompanying drawings and detailed description：
Fig. 1 is the overall structure sectional view of the present invention.
Label declaration：1- input shafts, 2- output shafts, 3- torsion bars, 4- endoporus, 5- shaft ends, 6- axis holes, 7- alignment pins, 8- without
Oily axle sleeve.
Embodiment
Below against accompanying drawing, by the description to embodiment, each structure for example involved to the embodiment of the present invention
Mutual alignment and annexation, the effect of each several part and operation principle, manufacturing process between the shape of part, construction, each several part
And operate with method etc., be described in further detail, with help those skilled in the art to the present invention inventive concept,
Technical scheme has more complete, accurate and deep understanding.
Reference picture 1, EPS spindle mounted structures of the invention relate generally to input shaft 1, output shaft 2 and torsion bar 3, torsion bar 3
It is connected between input shaft 1 and output shaft 2.
Input shaft 1 and output shaft 2 are provided with the endoporus 4 inserted respectively for two shaft ends of torsion bar 3, two shaft ends 5 of torsion bar 3
It is respectively equipped with vertical with central shaft and is in conplane positioning hole, it is corresponding in the endoporus side wall of input shaft 1 and output shaft 2
The opening position of positioning hole is respectively equipped with jack.
Two shaft ends 5 of torsion bar 3 are inserted into the endoporus 4 of input shaft 1 and output shaft 2 in a manner of quantitative gap coordinates respectively
Interior, corresponding positioning hole and receptacle alignment form the axis hole 6 of insertion, and it is fixed to be pressed with axis hole 6 in a manner of quantitative interference fit
