Description
Technical field
A kind of transfer is the utility model is related to, specifically a kind of steering column rolling for connecting removable rotation
Bead steering drive axle, it is primarily adapted for use in heavy truck vehicle.
Background technology
At present, common steering column transmission shaft type of attachment has a variety of.In composition, usually all it is by axis and axle sleeve group
Into axis uses spline structure with set, and one nylon jacket of riveting on one layer of nylon material or axis is coated on axis；These structures are to axis, inner room
Fit tolerance is more demanding, and installation difficulty is larger, and nylon is fragile on axis, and rejection rate is higher, is requiring steering gap compared with h,
Sliding extension power is larger.
Utility model content
The purpose of this utility model be to provide one kind can transmit moment of torsion, it is capable of expansion and contraction, reverse that gap is small, sliding extension power
The steering column Ball Transmission shaft device small, interchangeability is good, Ball Transmission shaft device is simple in structure, easily manufactured, dependable performance,
Interchangeability and good airproof performance, and can effectively solve the problems, such as existing driveline fit clearance.
Technical solution is used by the utility model：The ball-type steering drive axle includes driving sleeve, spacing is passing
Transmission shaft I and transmission shaft II in moving axis set, transmission shaft I are socketed in transmission shaft II, are characterized in that：The transmission shaft I
On be socketed with ball retainer and baffle ring；Driving sleeve end is equipped with sealing structure, and transmission shaft I passes through after being combined with transmission shaft II
Sealing structure is spacing.
The sealing structure includes sealing cover, collar, rubber sleeve, sealing ring and the modeling being sleeved on successively on transmission shaft II
Property axle sleeve.
There are four concave groove distributions in 90 ° in the outer surface of sealing cover, opposite with the annular groove of driving sleeve outer surface
Should, transmission shaft is with after driving sleeve assembling, being sleeved on the sealing cover on transmission shaft together with axle sleeve riveting, formation one is tubular close
Protective case is sealed, twice rubber seal is provided with inside protective case, makes to form a space being fully sealed in telescopic.Assembling
When in driving sleeve disposably smear lubricating grease, whole driveline will not be corroded by extraneous sand and dust, not only dust-proof
And antirust, service free.
The transmission shaft I is interference fitted in transmission shaft II or is welded in transmission shaft II by spline.
The transmission shaft I is hollow shaft, and transmission shaft II is solid shafting.
The ball retainer is equipped with two to four row balls, and each column is equipped with five.Moment of torsion is transmitted according to different automobile types
It is required that uniformly distributed two to four arc grooves on transmission shaft II, form one group of ball road with the arc groove on driving sleeve, will inlay
The ball retainer of embedding ball arc groove along axis is inserted in, it is necessary to when flexible, and ball rolls under the maintenance of ball retainer in cylinder
Move in circles rolling in road, and so as to fulfill the relative motion between transmission shaft and driving sleeve, ball rolls on raceway, avoids
Cambered surface (nylon material) on conventional axis is directly contacted with axle sleeve cambered surface, and sliding friction is instead of with rolling friction, can be with
The flexible contact engaging and separating force of axis and inner room is reduced, extends the service life of driving-shaft assembly.
The beneficial effects of the utility model：Transmission shaft I is hollow shaft, and transmission shaft II is solid shafting, is matched somebody with somebody by spline interference
Connection is closed, is fixed together by the way of steel pressure, to eliminate axial gap, prevents play.Transmission shaft is largely using hollow
Pipe, can so reduce the weight of whole driveline, meet automotive light weight technology requirement.Uniformly distributed two arc grooves on transmission shaft I,
Uniformly distributed two pairs of arc grooves form one group of ball road on driving sleeve, and ball is embedded on nylon ball retainer and is inserted in axis
Set, ball is under the maintenance of ball retainer, and move in circles rolling in arc raceway, and instead of slip with rolling friction rubs
Wipe, slided so as to fulfill low resistance between transmission shaft and driving sleeve.Driving sleeve inner wall is distributed for four arc grooves in 90 °,
Because arc groove shape matches with bead shape.Ball retainer is made of self-lubricating nylon, and the symmetrical both sides shape of retainer is each
It is different, it is simultaneously circular trough, ball is equidistantly symmetrically embedded on the circular trough of retainer, shape and the driving sleeve inner wall of opposite side
Arc groove match, be conducive to integrally-built stabilization.Form transmission of the transmission shaft with driving sleeve using arrangement ball
Moment of torsion, according to torque is transmitted, selects the number of each column ball and the columns of ball, preferred five, each column ball, two row or
Four row balls, ball is on ball retainer, stability when ensureing to transmit moment of torsion.Sealing cover together with axle sleeve riveting,
Inside sets twice rubber seal, and whole seal assembly makes axis be internally formed a space being fully sealed with set, avoids inside
Service life is improved by the erosion of extraneous sand and dust, ensures the fitment stability of ball-type transmission shaft.
