Technical field
The utility model relates to a kind of wheel steering system, particularly relates to a kind of bogie of car tween drive shaft structure.
Background technology
Tween drive shaft is as a vitals in the automobile steering system, and its performance not only has influence on the vehicle drive traveling comfort, the more important thing is the safety performance that influences automobile.Tween drive shaft generally is divided into fixed type and sliding type.Notification number is that the Chinese utility model patent of CN201009927Y discloses a kind of fixed tween drive shaft structure, it comprises universal-joint, rubber shaft coupling knot and steering column, and above-mentioned member is being linked in sequence of coaxial line, universal-joint is connected with steering box, steering column is connected with steering handwheel, between described rubber shaft coupling knot and steering column, bellows is set, and is being connected of coaxial line with steering column with rubber shaft coupling knot.The caoutchouc elasticity that this utility model is tied by the rubber shaft coupling is out of shape and the bellows axial elasticity is out of shape the vibration of the torsional direction that produces when absorbing vehicle ' and axial vibration, thereby has improved the driver comfort and the running safety of chaufeur.Notification number is that the Chinese utility model patent of CN201169288Y discloses a kind of employing spline bonded assembly sliding type tween drive shaft structure, it is with between the female splines and center cross male splines of countershaft assembly at existing steering column, added one and had lining wear-resisting, decrease of noise functions, thereby constituted a kind of new structure by female splines slide bushing and the non-direct contact of male splines transmission center cross.This structure can effectively reduce rotational noise, prolongs the service life of product.
Adopt spline sliding block joint mode, generally comprise a joint fork shaft and a joint breeches pipe, be equipped with spline on the cylindrical of joint fork shaft and on the interior circle of joint breeches pipe; Described joint fork shaft is connected by spline with the joint breeches pipe realizes turning to torque transmission, and by described joint fork shaft and joint breeches pipe slide up and down the absorption vehicle ' time vibration that produces.Yet because the restriction of processing technology, can there be a cambered surface usually in the not end of spline, when stuck phenomenon very easily takes place when end position slides into described joint fork shaft root described joint breeches pipe; In addition, because the existence in spline error gap makes described joint fork shaft and the joint breeches pipe generation metal impact noise in the relative motion process.
Summary of the invention
The utility model main purpose is in order to solve joint fork shaft and the stuck problem that saves the breeches pipe appearance in the prior art; Simultaneously, also in order to solve joint fork shaft and joint breeches pipe generation metal impact noise problem in the relative motion process, a kind of bogie of car tween drive shaft is provided, by structural development in described joint fork shaft and joint breeches pipe junction, prevent to save the stuck phenomenon of fork shaft and the appearance of joint breeches pipe, simultaneously, reduce joint fork shaft and joint breeches pipe generation metal impact noise in the relative motion process.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of bogie of car tween drive shaft comprises joint fork shaft and joint breeches pipe; Described joint fork shaft and joint breeches pipe are connected together by spline housing, and formation can even in axial sliding part; It also comprises a vibration isolation cover, and described vibration isolation is set on the mouth end of described joint breeches pipe and the mouth end that part is stretched out described joint breeches pipe, and described vibration isolation cover is set on the described joint fork shaft with described joint breeches pipe.By mouth end the mouth end that a vibration isolation cover and part are stretched out described joint breeches pipe is set, stretches out the stopping of mouth end parts of described joint breeches pipe by described vibration isolation cover, avoid described joint breeches pipe to slip into end position and to save fork shaft stuck at described joint breeches pipe.
As a kind of optimal technical scheme of the utility model, on described joint breeches pipe excircle, be provided with an annular groove near a mouthful end place; On the inner periphery of described vibration isolation cover, be provided with a bulge loop; Described vibration isolation cover is connected to the mouth end of described joint breeches pipe by described bulge loop and annular groove.By this bulge loop and groove structure, making material is the vibration isolation cover of PA6 is connected to described joint breeches pipe by elastic deformation mouth end.This connection mode has characteristics simple in structure, easy for installation.
As a kind of optimal technical scheme of the utility model, the cross-sectional plane of described annular groove and bulge loop is semicircle.Cross-sectional plane is semi-round annular groove and bulge loop, when described vibration isolation cover with described joint fork shaft bump takes place, can pass through elastic deformation, absorbs the bump energy preferably.
As a kind of optimal technical scheme of the utility model, described vibration isolation is arranged with a big nose end and a small bore end; The aperture of described small bore end and described joint fork shaft are adaptive, and the aperture of described big nose end and described joint breeches pipe are adaptive; Between described small bore end and the big nose end is an annular shoulder block.Can avoid when bump strength is big by being provided with of this annular shoulder block, the bulge loop of described vibration isolation cover is deviate from from the annular groove of described joint breeches pipe and the slippage of described vibration isolation cover is taken place, and causes described joint breeches pipe and described joint fork shaft generation direct impact, produces stuck.
As a kind of optimal technical scheme of the utility model, it also comprises an O type circle and a rubber cradle; Described O type circle and rubber cradle are arranged between described joint fork nose end and the described annular shoulder block.By between described joint fork nose end and described annular shoulder block, adding O type circle and rubber cradle, make shock attenuation result better, simultaneously, can partly eliminate described joint fork shaft and joint breeches pipe spline bonded assembly gap error, reduce the subordinate impact noise.
By the technical solution of the utility model, eliminated tween drive shaft substantially in use, or the joint fork shaft is taken place and saves the breeches pipe stuck phenomenon in countershaft assembly in transit owing to vibrating or clashing into; Simultaneously, significantly reduced because of the metal impact noise that vibrates or bump produces by the technical solution of the utility model; Increased the handling comfort of automobile steering system, the use that makes automobile steering system is reliable more, safety.
