Description
Technical field
The utility model relates to auto steerer field, specifically a kind of electronlmobil torsion deflector.
Background technology
The torsion bar of the automobile power steering generally used at present is rigid body, moment of torsion near intermediate position is inadequate, thus cause the elastic torsion curve of torsion bar to be linear torque curve, indifferent and central segment road feel is bad in automatically the returning of torsion bar, the stability that automobile turns in running at high speed and the not good problem of accuracy.
Summary of the invention
The utility model aims to provide a kind of practical electronlmobil torsion deflector.
For achieving the above object, the utility model provides following technical scheme: the deflector of a kind of electronlmobil torsion, comprise the body of rod, ring set, guide, steel ball, feather key and pressure spring, two ring sets are provided with outside the described body of rod, on the end face that two ring sets are corresponding, average mark is furnished with two pairs of guides, be provided with steel ball between every a pair guide, wherein the contact portion of a guide and steel ball is butterfly curved surface, the contact portion semicircular in shape face of another guide and steel ball; Two feather keys are equipped with between two ring sets and the body of rod; One end of the body of rod slightly thick and with the end contact of ring set, the body of rod outside another ring set is provided with pressure spring, and the body of rod outside pressure spring is provided with setting nut; The body of rod disconnects near ring set becomes two parts, and this two parts body of rod inside is circular hole, arranges a torsion bar and be fixedly connected with by two parts body of rod in circular hole.
Preferably, the quantity of described feather key determines according to actual conditions.
Preferably, the body of rod after described setting nut is also provided with and cap.
Compared with prior art, the beneficial effects of the utility model are: this electronlmobil torsion deflector, because power twister is provided with two to above guide, steel ball is provided with between every a pair guide, wherein the contact portion of a guide and steel ball is butterfly curved surface, the contact portion semicircular in shape face of another guide and steel ball, this power twister is also provided with a springing, when steel ball when between two guides is moved under the effect of external force, due to the existence of springing, just can increase the moment of torsion near torsion bar midway location, that improves torsion bar returns middle ability and central segment road feel automatically, add stability and accuracy that automobile turns in running at high speed, meet the torsion bar elastic torsion curve requirement of setting, from former linearly become non-linear, thus make the steering operation of automobile reach desirable hand force property curve and the requirement of road feel intensity, more can meet the requirement of automobile steering device to torsion bar.

Fig. 3 is the C-C section drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
Refer to Fig. 1-2, in the utility model embodiment, the deflector of a kind of electronlmobil torsion, comprise the body of rod 1, ring set 2, guide 3, steel ball 4, feather key 5 and pressure spring 6, on the end face being provided with two ring sets, 2, two ring set 2 correspondences outside the described body of rod 1, average mark is furnished with two pairs of guides 3, is provided with steel ball 4 between every a pair guide 3, wherein a guide 3 is butterfly curved surface with the contact portion of steel ball 4, the contact portion semicircular in shape face of another guide 3 and steel ball 4; Be equipped with two feather keys 5 between two ring sets 2 and the body of rod 1, the effect of feather key 5 is that guarantee two ring set 2 only moves axially along the body of rod 1, and the quantity of feather key 5 determines according to actual conditions; One end of the body of rod 1 slightly thick and with the end contact of ring set 2, the body of rod 1 outside another ring set 2 is provided with pressure spring 6, the body of rod 1 outside pressure spring 6 is provided with setting nut 7, can reach by regulating this setting nut 7 regulate pressure spring 6 pairs of guides 3 produce the effect of pressure; The body of rod 1 after setting nut 7 is also provided with and cap 8, and cap 8 is for secured adjusted nut 7; The body of rod 1 disconnects near ring set becomes two parts, and this two parts body of rod inside is circular hole, arranges a torsion bar 9 and be fixedly connected with by two parts body of rod in circular hole; Power twister of the present utility model and traditional torsion bar with the use of or be used alone, all can realize the purpose of this utility model.
Embodiment two
Refer to Fig. 3, torsion bar 9 of the present utility model is fixedly connected with input shaft 10, the flexible ring 11 of input shaft 10 peripheral hardware, between input shaft 10 and resilient ring 11, average mark is furnished with two pairs of guides 3, have a guide 3 to be fixedly connected with input shaft 10 in often pair of guide 3, another guide 3 is fixedly connected with inside resilient ring 11; Be provided with steel ball 4 between every a pair guide 3, wherein a guide 3 is butterfly curved surface with the contact portion of steel ball 4, the contact portion semicircular in shape face of another guide 3 and steel ball 4.Described guide 3 also can arrange two to more than, as long as be evenly distributed, when guide be 2 to, 4 right, handling ease when namely steel ball number is 2,4; According to different situations, the utility model changes torsion bar spring curve by the butterfly curved surface angle that changes guide and steel ball contact portion and the preload that changes spring, and above-mentioned change is all to realize the purpose of this utility model for spending.
