Abstract

The present invention relates to a kind of air pressure balance structures of super large slippage automobile axle shaft, including spline tube axis and splined shaft, one end of the spline tube axis is axially provided with spline tube, one end of the splined shaft is the spline connection being axially inserted into spline tube, the other end of the spline tube axis and splined shaft is connected with universal joint respectively, it is socketed with boot seal between one end of the spline tube and the outside of splined shaft, the center of the spline tube axis and splined shaft is provided with the venthole at perforation both ends.The present invention is improved using simple structure, is solved the problems, such as bulging when boot seal work and is inhaled flat.

Description

A kind of air pressure balance structure of super large slippage automobile axle shaft
Technical field
The present invention relates to automobile axle shaft fields, more particularly to a kind of air pressure balance knot of super large slippage automobile axle shaft Structure.
Background technique
Automobile drive semiaxis is also drive axle, and Automobile drive semiaxis is that the solid of torque is transmitted between differential mechanism and driving wheel Axis, inner end generally pass through spline and connect with axle shaft gear, and outer end is connect with wheel hub, and what is researched and developed now is a kind of axial sliding The semi-axis structure of shifting amount super large, present design is that a closed space is arranged in the position of Relative sliding, when splined shaft pressure It is reduced to spline tube bottom and is stretched to spline tube oral area, under the two state, the volume of confined space reaches 1:4, and is mounted on outer The boot seal of side can not adapt to 75% rate of volumetric change, since the presence of inner air is when confined space compresses, rubber Glue dirt-proof boot can serious bulging, when confined space stretch when, boot seal can by inhale it is flat, lead to not work, for shifting amount This is to be difficult to solve the problems, such as to the semi-axis structure of super large,
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of air pressure balance structures of super large slippage automobile axle shaft, adopt It is improved, solve the problems, such as bulging when boot seal work and inhaled flat with simple structure.
The technical solution adopted by the present invention to solve the technical problems is: providing a kind of gas of super large slippage automobile axle shaft Balanced structure, including spline tube axis and splined shaft, one end of the spline tube axis is pressed axially to be provided with spline tube, the flower One end of key axis is the spline connection being axially inserted into spline tube, the other end difference of the spline tube axis and splined shaft It is connected with universal joint, boot seal, the spline is socketed between one end of the spline tube and the outside of splined shaft The center of cylinder axis and splined shaft is provided with the venthole at perforation both ends.
As a supplement to the technical solution of the present invention, the spline connection of described splined shaft one end uses Be ball spline.
Further, to be socketed with end between universal joint on the outside of the other end of the spline tube axis and splined shaft dust-proof Set.
The utility model has the advantages that the present invention relates to a kind of air pressure balance structure of super large slippage automobile axle shaft, it is simple and reasonable, It is arranged with venthole in the middle part of spline tube axis and splined shaft, increases the confined space between spline tube and splined shaft, this The volume change of confined space is 3:4, rate of volumetric change by original 1:4 variation when sample spline tube axis and splined shaft relative motion It is reduced to 25%, such volume variation will not lead to the problem of bulging and inhale flat, realization when so that boot seal is worked The automobile axle shaft for solving super large slippage under the premise of not changing semi-axis structure overall dimensions is for a long time difficult to solve Certainly the technical issues of.
Detailed description of the invention
Fig. 1 is the half-sectional structure chart of main view of the invention.
Diagram: 1, universal joint;2, end dirt-proof boot;3, splined shaft;4, boot seal;5, spline connection;6, spline Cylinder;7, spline tube axis;8, venthole.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited Range.
As shown in Figure 1, the technical solution adopted by the present invention to solve the technical problems is: providing a kind of super large slippage vapour The air pressure balance structure of vehicle semiaxis, including spline tube axis 7 and splined shaft 3, one end of the spline tube axis 7 are axially provided with flower Key cylinder 6, one end of the splined shaft 3 are the spline connection 5 being axially inserted into spline tube 6,7 He of spline tube axis The other end of splined shaft 3 is connected with universal joint 1 respectively, is socketed between one end of the spline tube 6 and the outside of splined shaft 3 The center of boot seal 4, the spline tube axis 7 and splined shaft 3 is provided with the venthole 8 at perforation both ends.
The spline connection 5 of described 3 one end of splined shaft is using ball spline, the spline tube axis 7 and spline It is socketed with end dirt-proof boot 2 between universal joint 1 on the outside of the other end of axis 3, ball spline is that one kind slides axially than smoothly Connection structure, and cost is relatively low, end dirt-proof boot 2 make the end of spline tube axis 7 and splined shaft 3 also formed one it is closed Space.
As a kind of embodiment of the invention, when in use, spline tube axis 7 and splined shaft 3 can move to axial It is dynamic, the compression for the confined space inside spline tube 6 is realized, since venthole 8 is by the confined space and flower inside spline tube 6 The confined space formed between key cylinder axis 7 and splined shaft 3 and universal joint 1 is connected, and expands the volume of confined space, makes when flower Key axis is compressed to spline tube bottom and is stretched under both spline tube oral area states, and the volume of confined space reaches 3:4, volume Change rate is reduced to 25%, and such volume variation will not generate bulging when so that boot seal is worked and inhale flat ask Topic.
