The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in following Fig. 1-5, a kind of automobile gear shift flexible shaft mechanism, comprise two steel ropes 1 and be enclosed within the wire rope casing 2 outside steel rope 1, the outer end of wire rope casing 2 has one for being fixed on the selector permanent joint 8 on gearshift base, steel rope outer end 3 passes wire rope casing and for being connected with the handle of gearshift, wire rope casing 2 midways location are for passing movably the via hole on body bottom panel, and wire rope casing 2 the inners have one for being connected to the change speed gear box permanent joint 5 on change speed gear box, steel rope the inner 4 passes steel wire loop and for being connected with change speed gear box rocking arm, during concrete enforcement, on described wire rope casing 2, be positioned at inner position, middle part and be also fixedly installed one for being fixed on the guide-localization support 6 of body bottom panel lower surface.Described guide-localization support 6 has a connecting portion 61 that is connected and supplies steel wire loop to pass with two steel wire loops, and a fixed part 62 along the reverse bending obliquely upward of connecting portion extension, has two for fixing screw 63 on fixed part 62.Described wire rope casing 2 midways location be also provided with for body bottom panel on via hole in mating connection every make an uproar pad 7.Described every the pad 7 employing elastomeric materials of making an uproar.Described every make an uproar pad 7 upper surface peripheries be provided with the sound insulation convex 71 that two circles make progress.Described have a circle metallic framework 72 every pad 7 lower surfaces of making an uproar, and on metallic framework 72, two ends have the fixing threaded hole 73 coordinating with binding bolt, and fixing threaded hole 73 is positioned at sound insulation convex outside.Described have two and respectively confess that steel wire loop passes connected connecting bore every pad 7 middle parts of making an uproar, the whole oblique setting of described connecting bore and that bottom 74 be and steel wire loop 2 external diameters mate is cylindrical, 75Wei lower end, connecting bore top and cylindrical linking upper end diameter become large cone barrel.During concrete enforcement, in described connecting bore, the direction of the axial line of upper end cone barrel cylindrical axle center line along lower end tilts upward again.
This gear shift flexible axle groundwork principle: 1) driver is by applying power to shift handle ball, 2) in the leverage by gearshift is moved gear selecting flexible axle by larger trying hard to recommend, steel rope moves in sleeve pipe, 3) by steel rope, power is delivered to change speed gear box gear shift rocking arm place again, final realization by driver's wish shifting position.
In the utility model, far-end gearshift arrangement, larger in flexible axle span, this allows wire rope casing under the effect of power, have certain buckling deformation ability.In order to guarantee that the trend of flexible axle is conducive to the transmission of power and sound insulation every the ability of making an uproar.So will go when the flexible axle arrangement form of this large span, need to there is gear shift guide-localization bracket component and the reasonably design of flexible axle via structure.Under real vehicle installing condition, rubber every the angle of the upper and lower both ends of the surface flexible axle axis of pad of making an uproar not etc., again because flexible axle and sleeve pipe and rubber pad have certain intensity.If rubber seal via hole is designed to lower surface cylindrical hole and upper surface taper hole by cutaway view A-A and B-B, can eliminate preferably flexible axle sleeve pipe and rubber every the internal stress of the pad of making an uproar and dredge the upper and lower two ends of flexible axle naturally excessively, also allowing flexible axle sleeve pipe better through rubber pad via hole simultaneously.
The utlity model has following advantage: far-end gearshift arrangement, when flexible axle span is larger:
1) gear shift flexible axle guide-localization bracket component actv. has guaranteed that the reasonable trend of flexible axle is conducive to the transmission of power, the ride comfort of gearshift and the end vibration of decay change speed gear box and amplitude are delivered to the adverse effect in vehicle body and operator's compartment by flexible axle.
2) every rubber cushion component rubber via hole upper end deep taper hole structure and the lower end cylindrical hole structure of making an uproar, guaranteed and the rational interference fit area of flexible axle sleeve pipe, also allow flexible axle sleeve pipe be convenient to through rubber pad, can finely allow flexible axle flexible axle sleeve pipe when gear shifting force impacts reliable in rubber cushion component place distortion sealing all the time.Meanwhile, can eliminate preferably again flexible axle sleeve pipe and rubber every the internal force of the pad of making an uproar, dredge the upper and lower two ends of flexible axle naturally excessively.
3) twice convex also has good sound insulation every the ability of making an uproar after extruding is in place.
