Abstract
The utility model provides a steering device of an anti-dropping member which is simple in structure and prevents a male spline shaft from dropping relative to a female spline shaft. When a male steering shaft (12B) further moves towards the left side, the inner circumference of a hollow disc part (722) further undergoes hole shrinkage and is buckled on the outer circumference (51) of the male steering shaft (12B), elastic deformation of the hollow disc part (722) towards the left side is refrained, and a male spline (50) cannot be dropped towards the left side from a female spline (60). By bending the hollow disc part (722) at a bent angle (alpha2) of over 90 degrees, the male spline (50) cannot be dropped from the female spline (60). Accordingly, the steering device is simple in structure, and manufacturing cost can be reduced.
Description
Technical field
The utility model relates to steering hardware, particularly have can relatively move on direction of principal axis and can transmitting torque the chimeric steering shaft in ground and the steering hardware of tween drive shaft.
Background technology
Existence by column jacket and inner prop can be on direction of principal axis the telescopic steering hardware of the adjustment of the telescopic location of chimeric and travel direction dish slidably.In addition, there is the steering hardware of tilt telescopic formula of the telescopic location of travel direction dish and obliquity both sides' adjustment.
In such steering hardware, after the adjustment of telescopic location is completed, will have the column jacket undergauge of groove, and the periphery of inner prop will be anchored on the interior week of column jacket, the inner prop clamping is got and can not relatively move on direction of principal axis with respect to column jacket.In addition, be equipped with at the car body rear side on the upper steering shaft of bearing circle, lower steering shaft can telescopic moving by spline fitted the ground engaging, the rotation of bearing circle to the steering gear transmission, is changed the deflection angle of wheel.
In such steering hardware, be installed on the steering hardware of the state before car body or the steering hardware of the state that breaks away from from car body is removed the flexible clamping relative with column jacket of inner prop because of the maloperation control lever sometimes when collision.So, produce inner prop from column jacket comes off, the spline fitted of steering shaft also comes off unfavorable condition.Patent documentation 1 part that is covered with dust for preventing dust and/or water from facing south the peristome of castellated shaft and cloudy castellated shaft entering, but do not prevent that positive castellated shaft is with respect to the function that comes off of cloudy castellated shaft.
Fig. 7 means the sectional side elevation of the chimerism of the cloudy steering shaft of the slip-off preventing member that has in the past and positive steering shaft, and Fig. 8 means that the step surface apical grafting of positive spline of Fig. 7 middle-jiao yang, function of the spleen and stomach steering shaft is in the sectional side elevation of the state of slip-off preventing member.To shown in Figure 8, be formed at the positive spline 50 embedded (namely chimeric from the inboard) on right side of outer peripheral face 51 of positive steering shaft 12B in the cloudy spline 60 in the left side of the inner peripheral surface 61 that is formed at cloudy steering shaft 12A as Fig. 7, and spline fitted.
On the outer peripheral face 62 of cloudy steering shaft 12A, be pressed in the open side end of cloudy steering shaft 12A (left end of cloudy steering shaft 12A) and be fixed with slip-off preventing member 71.Slip-off preventing member 71 is made of hollow cylinder section 711 and hollow disc section 712.Hollow cylinder section 711 is pressed into the outer peripheral face 62 that is fixed in cloudy steering shaft 12A.Hollow disc section 712 from hollow cylindrical portion 711 on the sunny side the outer peripheral face 51 of steering shaft 12B with bending angle α 1 bending of 90 degree, cover the gap between the outer peripheral face 51 of the peristome of cloudy steering shaft 12A and positive steering shaft 12B.
Under the state of Fig. 7, between the inner peripheral surface of the outer peripheral face 51 of positive steering shaft 12B and hollow disc section 712, be formed with the gap beta 1 of a little, make axial relatively move relative with cloudy steering shaft 12A of positive steering shaft 12B to carry out smoothly.
As shown in Figure 8, when positive steering shaft 12B moves to the left with respect to cloudy steering shaft 12A, peristome side stage terrace 52 apical graftings of sun spline 50 are in the hollow disc section 712 of slip-off preventing member 71, and to the left the movement relative with cloudy steering shaft 12A of positive steering shaft 12B temporarily stops.But, if with respect to the positive steering shaft 12B larger load of directive effect left, hollow disc section 712 is pressed by peristome side stage terrace 52 and elastic deformation to the left, the inner peripheral surface hole enlargement of hollow disc section 712, the tooth top 53 of sun spline 50 becomes and can move along the inner peripheral surface of hollow disc section 712, produces the unfavorable condition that positive spline 50 comes off to the left from cloudy spline 60.
