Description
Technical field
It is especially a kind of to improve torsion stiffness, reducing noise and vibration the utility model is related to jackshaft technical field
Jackshaft public affairs axis with injection molding ring.
Background technology
Jackshaft is one of the main motion parts in automobile steering system, has and transmits torque, crumple and good NVH
Performance.Spline connection is made of internal spline and external splines.Inside and outside spline is multiple tooth part, the spline on inner periphery
For internal spline, the spline on outer cylinder surface is external splines.Obviously, spline connection is development of the Flat dey joint in number.
Spline is normal structure.
In automobile steering system, countershaft assembly is typically all by upper and lower two section forks and four sub- parts of male and female axis
Assembly connection forms, and adds riveting using spline interference connection between section fork and axis, and there are many connection types between male and female axis,
In one is using spline connect.But as the requirement of major automobile main frame maker is higher and higher, especially to the torsion of jackshaft
Turn rigidity and noise, design before cannot meet the requirement of client.
The jackshaft public affairs axis with injection molding ring for needing a kind of raising torsion stiffness, reducing noise and vibration.
Utility model content
The purpose of this utility model be to provide a kind of raising torsion stiffness, reduce noise and vibration in injection molding ring
Countershaft public affairs axis.
A kind of jackshaft public affairs axis with injection molding ring, including：
Public axis, the lower section fork of one end setting of the public affairs axis, the other end are arranged three injection molding rings, are arranged between the injection molding ring
Side spline is respectively set in the outermost of intermediate spline, the injection molding ring, and the injection molding ring is equal with the intermediate width of spline, described
Side setting inside spline of the side spline close to lower section fork；
Mother's axle, the mother's axle one end setting on save fork, the other end be arranged spline, respectively with intermediate spline, side spline
With inside spline fitted, respectively with intermediate spline, the notch of side spline and inside spline corresponds to the spline.
The intermediate spline and side spline are respectively equipped with two.
The width of the side spline is less than the width of intermediate spline.
The width of the inside spline is more than the width of side spline, is less than the width of intermediate spline.
The lower section fork and upper section fork are respectively fork shape, are divided into two plugs, through-hole is arranged on the plug.
Section fork under one end setting of the utility model public affairs axis, three injection molding rings are arranged in the other end, in being arranged between injection molding ring
Between spline, the outermost for being molded ring is respectively set side spline, and injection molding ring is equal with the centre width of spline, and side spline is close to lower section
The side setting inside spline of fork；On one end of mother's axle save fork, the other end be arranged spline, respectively with intermediate spline, side spline
With inside spline fitted, respectively with intermediate spline, the notch of side spline and inside spline corresponds to spline.The utility model improves
Torsion stiffness reduces noise and vibration.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the utility model mother's axle and upper section pitch structural schematic diagram；
Fig. 3 is the structural schematic diagram after the utility model assembly；
In figure：1, public axis, 2, injection molding ring, 3, intermediate spline, 4, side spline, 5, lower section pitch, 6, inside spline, 7, mother's axle,
8, upper section fork.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of jackshaft public affairs axis with injection molding ring, including：Public axis 1, the lower section fork 5 of one end setting of public axis 1, the other end is set
Three injection molding rings 2 are set, the intermediate spline 3 of setting between ring 2 is molded, the outermost of injection molding ring 2 is respectively set side spline 4, is molded ring
2 is equal with the width of intermediate spline 3, side setting inside spline 6 of the side spline 4 close to lower section fork 5；Mother's axle 7, the one of mother's axle 7
Section fork 8 in the setting of end, spline is arranged in the other end, coordinates respectively with intermediate spline 3, side spline 4 and inside spline 6, spline
Respectively with intermediate spline 3, the notch of side spline 4 and inside spline 6 corresponds to.
Intermediate spline 3 and side spline 4 are respectively equipped with two.The width of side spline 4 is less than the width of intermediate spline 3.Inside
The width of spline 6 is more than the width of side spline 4, is less than the width of intermediate spline 3.Lower section fork 5 and upper section fork 8 are respectively fork
Shape is divided into two plugs, through-hole is arranged on plug.
The design of three injection molding rings 2 improves the torsion stiffness of jackshaft, also plays the role of improvement to vibration and noise, complete
Client's requirement new to jackshaft all can be met.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
The principle of utility model, on the premise of not departing from the spirit and scope of the utility model the utility model also have various change and
It improves, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope by
Appended claims and its equivalent define.
