Description

A kind of automobile primary electronic-controlled power steering section
Technical field
The present invention relates to automobile power steering technical field, more particularly to a kind of automobile primary electronic-controlled power steering section.
Background technology
Automobile typically uses electronic-controlled power steering force aid system to reduce the steering force needed for Vehicular turn.Knuckle is automobile One of major part on steeraxle, can be such that vehicle steadily travels and sensitive transmission travel direction, the function of knuckle is to hold By automotive front load, support and drive front-wheel to be rotated around stub and make motor turning.Under motoring condition, it subjects Changeable shock loading, it is therefore desirable to which it has very high intensity.Because knuckle is one of important parts, thus it is right Installation accuracy during assembling also has very strict requirements, and otherwise the security to automobile can have a great impact, and easily triggers and hands over Interpreter's event.
Knuckle species is also varied, most important of which is that the knuckle used during active force transmission, this kind of steering Section is to hardness and requirement on machining accuracy highest, because it is to determine that automobile power inputs topmost part.But different hairs Motivation for active force knuckle the need for it is also different.In order to preferably coordinate the new-energy automobile power of my company's new production A kind of new automobile primary electronic-controlled power steering section has been invented by input system, my company.
The content of the invention
It is an object of the invention to provide a kind of automobile primary electronic-controlled power steering section, machining accuracy is higher, can be newborn to my company The new-energy automobile of production provides more preferable active force and turned to.
Technical scheme is as follows:
A kind of automobile primary electronic-controlled power steering section, including main body, with the integrally formed arc branch angle of the main body, oblique branch angle, auxiliary Branch angle, the first short branch angle and the second short branch angle are helped, the main body is provided with inner seal ring, the main body and is additionally provided with assembly bench Post and the assembling of arc branch angle second post, the arc branch angle second are assembled provided with arc branch angle first in rank, the arc branch angle Assemble post and be provided with the second pilot hole of arc branch angle;Post, the oblique branch angle assembling post are assembled provided with oblique branch angle in the oblique branch angle It is provided with oblique branch angle pilot hole;The center line of the center line of the pilot hole of arc branch angle second and the oblique branch angle pilot hole exists In same level, the first short branch angle is provided with the first short branch angle assembling post;The two of the assembling of arc branch angle first post Individual end face is beyond two end face 2.5mm at the arc branch angle, and two end faces of the oblique branch angle assembling post are beyond described Two end face 1.2mm at oblique branch angle, the upper surface of the first short branch angle assembling post exceeds the described first short branch angle upper surface 1mm。
Further, the upper surface at the described first short branch angle and the drop of the upper surface at the described second short branch angle are 3mm.
Further, the main body is made up of superior alloy steel.
Beneficial effects of the present invention:
The present invention's can apply to new-energy automobile active force steering, make active force output effect more preferably, performance It is more stable.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
In figure:1st, main body, 2, arc branch angle, 3, oblique branch angle, 4, auxiliary branch angle, the 5, first short branch angle, the 6, second short branch angle, 7th, inner seal ring, 8, assembling step, 9, arc branch angle first assembling post, 10, arc branch angle second assembling post, 11, oblique branch angle dress With post, the 12, first short branch angle assembling post, 13, the second pilot hole of arc branch angle, 14, oblique branch angle pilot hole.
Embodiment
As shown in figure 1, a kind of automobile primary electronic-controlled power steering section, mainly includes main body 1, with the integrally formed arc of the main body 1 Shape branch angle 2, oblique branch angle 3, auxiliary branch angle 4, the first short branch angle 6 in short branch angle 5 and second, have collectively constituted whole automobile active force and have turned Xiang Jie.The main body 1 is provided with inner seal ring 7, and the inner seal ring 7 is used cooperatively with main power shaft, makes automobile main power shaft Coordinate closer, better tightness is driven better.Assembling step 8 is additionally provided with the main body 1, is determined when convenient for assembly Whether appropriate location is assembled to, is brought great convenience to assembling.Assembled provided with arc branch angle first at the arc branch angle 2 There are two positions to provide bearing assembling on post 9 and the assembling of arc branch angle second post 10, arc branch angle 2.The arc branch angle Two assembling posts 10 are provided with the second pilot hole of arc branch angle 13, and post 11, oblique branch angle 3 are assembled in the oblique branch angle 3 provided with oblique branch angle Place is provided only with a rigging position, therefore can be with bigger steering force.The oblique branch angle assembling post 11 is provided with oblique branch angle Pilot hole 14;The center line of the center line of second pilot hole of arc branch angle 13 and the oblique branch angle pilot hole 14 is in same water In plane, do stress of two branch angles in overall structure and mutually cooperate, evenly, effect is more preferable for stress.Described first Short branch angle 5 is provided with the first short branch angle assembling post 12;Two end faces of the assembling of arc branch angle first post 9 exceed the arc Two end face 2.5mm at shape branch angle 2, indwelling a certain distance is to preferably ensure the mutual cooperation between line shaft.Institute Two end faces for stating oblique branch angle assembling post 11 exceed two end face 1.2mm at the oblique branch angle 3, by substantial amounts of experiment, such as Really this end face distance will influence the intensity of this part too much, and power laser propagation effect can be influenceed if too small.Described first The upper surface of short branch angle assembling post 12 exceeds the described first short upper surface 1mm of branch angle 5, makes part bulk strength more preferably, stress is more Uniformly.
Preferably, the upper surface at the first short branch angle 5 is 3mm with the drop of the upper surface at the described second short branch angle 6, The weight of part is set to have done further optimization on the basis of whole part strength is ensured.
Preferably, the main body 1 is made up of superior alloy steel, to ensure overall intensity system coefficient and overall use Life-span.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art For, on the premise of principle of the present invention is not departed from, some improvement or replacement can also be made, these improve or replaced It should be regarded as protection scope of the present invention.
