Description
Technical field
The utility model belongs to technical field of automobile parts, is related to a kind of universal joint, more particularly to a kind of side surface locking
It is universal to pitch successively.
Background technology
Universal joint, that is, universal joint, is the parts for realizing varied angle power transmission, for needing to change transmission axis direction
Position, section fork be indispensable part in universal joint, it is present section fork can be divided into locking section fork, welding section fork,
Riveting section fork and telescopic joint fork etc., are pitched successively wherein locking section fork is that common one kind is universal.Usually the one of locking section fork through hole
Side opens up groove, is then connected with two cell walls of groove, promotes universal joint to be deformed steering wheel inputting axis clamping.
But to facilitate installation, with the presence of certain gap at the cooperation of steering column and universal-joint fork, i.e., the through hole on universal joint is big
In the caliber of steering wheel input shaft.If the concentricity of steering wheel input shaft and the universal upper through hole of fork successively is bad, or gap
It is excessive, it can all cause the situation for occurring line contact at steering wheel input shaft and universal-joint fork cooperation, due to intermetallic friction system
Number is smaller, and the frictional force between installation rear universal joint fork and steering wheel input shaft is inadequate, since line contact can cause universal-joint fork
Unilateral stress, stress are seriously uneven, it is easy to because the yield stress in later stage produces pretightning force decay, cause not clamping, rotation side
Slided to appearance when disk, abnormal sound.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of uniform force, folder
The good side surface locking of tight effect is universal to be pitched successively.
The purpose of this utility model can be realized by following technical proposal：A kind of side surface locking is universal to be pitched successively, by even
Socket part and be arranged at connecting portion upper end both sides left engaging lug and right engaging lug composition section fork body, the left engaging lug and
The mounting hole laterally set is offered on right engaging lug respectively, the connecting portion offers the spline axis hole being vertically arranged, its
It is characterized in that, the front-end and back-end of the connecting portion are respectively provided with the tight lock part of outwardly convex, are opened in the middle part of the tight lock part
Equipped with the open seam being vertically arranged, with being connected inside spline axis hole, the sidepiece of the tight lock part is opened for the inner of the open seam
Equipped with locking hole.
As a result of above technical scheme, the universal one-way bolt pitched successively, which clamps, makes two-way bolt clamping into, universal
The stress and deformation pitched successively are evenly distributed, good to ensure to contact for face between spline shaft hole inner wall and steering wheel input shaft, from
And the reliability clamped is improved, avoid steering wheel input shaft from sliding.
In the universal fork successively of above-mentioned side surface locking, have outwards at the top of open seam on the tight lock part
The reaming of extension.The reaming can reduce locking resistance.
Pitch successively above-mentioned side surface locking is universal, the width of the open seam is 2.8mm between 3.2mm.
In the universal fork successively of above-mentioned side surface locking, the both ends of the reaming are made of the semicircle that radius is 3.5mm,
The width of the reaming is 11mm between 14mm.
Compared with prior art, universal pitch successively of this side surface locking is provided with tight lock part in the rear and front end of connecting portion,
So that its stress and deformation are evenly distributed.

Embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2, this side surface locking is universal pitches successively, by connecting portion 1 and is arranged at 1 upper end both sides of connecting portion
The section of left engaging lug 2 and right engaging lug 3 composition pitches body 4, and horizontal setting is offered respectively on left engaging lug 2 and right engaging lug 3
Mounting hole 5, connecting portion 1 offers the spline axis hole 6 being vertically arranged, and the front-end and back-end of connecting portion 1 are respectively provided with outwardly convex
Tight lock part 7, the middle part of tight lock part 7 offers the open seam 8 being vertically arranged, the inner of the open seam 8 with inside spline axis hole 6
It is connected, the sidepiece of tight lock part 7 offers locking hole 9, and the width of open seam 8 is 2.8mm between 3.2mm.
Further describe in detail, this side surface locking it is universal successively pitch in tight lock part 7 on positioned at open seam 8 top at have to
The reaming 10 of outer extension, the both ends of reaming 10 are made of the semicircle that radius is 3.5mm, the width of the reaming 10 for 11mm extremely
Between 14mm.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
