Accompanying drawing explanation
Fig. 1 is the positive indicating device one example structure schematic diagram of steering wheel return of the present invention; Fig. 2 is Fig. 1 plan structure schematic diagram.
The specific embodiment
For further understanding technical scheme of the present invention, by following examples, the invention will be further described by reference to the accompanying drawings.
The definite of steering wheel return positive position of the present invention (reset) is on bearing circle, to arrange one roughly the same or to be similarly skewed mutually with the inclination mode (angle and direction that comprises inclination) of bearing circle, the indicating device rotating with bearing circle, in the spiral ring type guide channel of indicating device, activity arranges one along with rotating of steering wheel move in spiral ring type guide channel (mobile or roll), and all-the-time stable stays in the indication body of intersection point point (position) in any circle of spiral ring type guide channel, utilize indication body with the rotation of bearing circle, to move all the time the position memory effect of the intersection point point position of the corresponding circle in spiral ring type guide channel, obtain positive position or the number of turns of steering wheel return.
Using the intersection point position of indication body of centre one circle passage of effective active coils (stroke) of spiral ring type guide channel as initial position (bearing circle starts the initial position of rotation), at bearing circle, after initial position is to a direction rotation to the position needing or the number of turns, return timing, gyratory directions dish is until indication body moves turns back to the initial position of spiral ring type guide channel or turn round the identical number of turns, and bearing circle just returns and put in place.
When take this initial position as threshold value or 0 circle, the inside and outside circle direction along spiral ring type guide channel arranges the number of turns mark corresponding to left and right rotation respectively.Can read this indication body by number of turns mark and in spiral ring type guide channel, along the mobile number of turns of respective direction (as inner ring or outer ring direction) or position, obtain the number of turns or the position that bearing circle rotates with respect to initial position, with directions dish, go back to the positive number of turns or position.
The positive indicating device of this steering wheel return as illustrated in fig. 1 and 2, the present embodiment comprises indicating device, its indicating device comprises transparent plastic material box body 2 and is arranged at the spiral ring type guide channel in transparent plastic material box body 2, and its spiral guide channel is the spiral coil pipe 3 that the common 6-7 of its number of turns and the bearing circle left-right rotation maximum number of turns that may reach encloses.Spiral coil pipe 3 consists of telfon plastic pipe.Transparent plastic material box body 2 is fixed on the axial location on steering wheel for vehicle 1 wall, spiral coil pipe 3 is fixed on the diapire face of transparent plastic material box body 2, and the degree of dip of inclined spiral coil pipe 3 can be identical with corresponding degree of dip and the direction of tilt of steering wheel for vehicle with direction of tilt etc.At spiral coil pipe 3 inner chamber rollers, be provided with the indication body being formed by a magnetic rolling body 4 with SN magnetic pole.
The magnetic rolling body 4 of SN magnetic pole can form intersection point point (position) 7 at each corresponding circle because of the inclination of spiral coil pipe 3, and after bearing circle 1 rotation the stable intersection point position 7 that stays in a corresponding circle of spiral coil pipe 3 from start to finish.Under normal (not doing normally travelling of left rotation and right rotation operation) state that the magnetic rolling body 4 of SN magnetic pole is not done to rotate at bearing circle 1 on the intersection point position 7 of centre one circle of the stable effective active coils that stays in spiral coil pipe 3, indicating device be take the intersection point position 7 of centre one circle of this effective active coils of spiral coil pipe 3 and is started to do the initial position 7a of left or right rotary manipulation as bearing circle.Take this initial position 7a as " 0 ", and for spiral coil pipe 3 arranges number of turns mark, the inside and outside circle direction along spiral coil pipe 3 arranges number of turns mark or the scale 5 corresponding to the left and right rotation of bearing circle respectively.This initial position 7a of usining starts left or right as bearing circle 1 and rotates, and the magnetic rolling body 4 with SN magnetic pole starts the start bit reset of rolling to respective direction, after turning to the angle or position needing, the magnetic rolling body of SN magnetic pole is also rolled to the intersection point position (as " b1 ") of a corresponding circle of spiral coil pipe thereupon, the number of turns or the position that are bearing circle rotation of number of turns mark 5 indications that this number of turns or position are corresponding, return timing, as long as make the magnetic rolling body of SN magnetic pole back be rolled to initial position 7a toward returning back to bearing circle, be that steering wheel return just puts in place, before bearing circle has also turned round, (as corresponding in b1 is a circle to the number of turns of rotation, direction dish has been played a circle left, as long as back steering wheel rotation makes the magnetic rolling body of SN magnetic pole back be rolled to raw bits reset place, steering wheel return just puts in place, bearing circle back makes a circle).
