Abstract
The invention discloses a steering transmission intermediate shaft which comprises a spline sleeve and a spline shaft, wherein the spline sleeve is in splined fit with the spline shaft. The other ends, opposite to the matched ends, of the spline sleeve and the spline shaft are provided with universal joint forks respectively. A spline jacket is arranged at the matched position of the spline sleeve and the spline shaft and provided with a grease storage groove, and an air permeable stopper cap is arranged at the outer end of the spline sleeve. Sufficient lubricant can be provided through the grease groove to guarantee reliability in long-term lubrication between the spline sleeve and the spline shaft, vacuumization in the spline sleeve can be avoided by the aid of the air permeable stopper cap to enable the steering transmission intermediate shaft to have fine sliding performance, and accordingly torque fluctuation in steering of a whole vehicle can be effectively avoided, and comfortableness and reliability in steering operation can be improved.
Description
Technical field
The present invention relates to Automotive Steering Technology field, especially relate to one and turn to jack shaft.
Background technique
Client requires more and more higher to vehicle security, and steering column is as chassis important component part, and in the collision safety of car load, its effect is self-evident.Along with the progress of technology, in the front of car load and Frontal offset impact process, when causing driver's leg and step space by compression in order to avoid engine compartment to the invasion of the space of cockpit, steering column mandrel makes its chest trauma evil or directly causes driver dead to driver's chest play, leg room is extruded and increases rescue difficulty, therefore collapse type tubing string is widely applied on car load, and shrinkable sliding steering jack shaft is also applied on car load gradually simultaneously.
At present, turn to jack shaft mostly to be splined sleeve and splined shaft is in mating connection, spline fitted is conducive to turning to the flexible of jack shaft, is convenient to plant personnel assembling and is conducive to turning to jack shaft crumple when there is complete automobile collision simultaneously.Client requires also more and more higher to car load travelling comfort, the particularly travelling comfort of handling maneuver.But turn to jack shaft can affect the reliability of lubricating because heating up and lacking oiling agent in long-term using process; Splined sleeve in use inside easily forms vacuum, affects the slip of jack shaft, and reduce the travelling comfort of steering operation, and the inside and outside pressure difference of splined sleeve is excessive, silt easily enters splined sleeve inside, the reliability that impact uses.
Summary of the invention
Technical problem to be solved by this invention is to provide one and turns to jack shaft, its objective is that, in Long-Time Service process, jack shaft has good lubrication and sliding capability, improves the travelling comfort of steering operation.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: one turns to jack shaft, comprise the splined sleeve by spline fitted and splined shaft, the other end that described splined sleeve and splined shaft match is equipped with universal-joint fork, described splined sleeve and splined shaft cooperation place are provided with spline boot, and spline boot is provided with grease storage groove.
The outer end of described splined sleeve is provided with gas permeability blanking cover.
Described gas permeability blanking cover is nylon washer.
Seal ring is provided with in described spline boot.
The excircle of described splined sleeve is provided with circular groove with spline boot cooperation place.
Described seal ring is rubber seal, and its internal diameter of the seal ring is less than the external diameter of splined shaft.
The present invention compared with prior art, have the following advantages: by arranging grease storage groove on spline boot, enough oiling agents are provided, ensure the reliability of the long-term lubrication between splined sleeve and splined shaft, and gas permeability blanking cover is set in splined sleeve one end, avoid forming vacuum in splined sleeve, make it have good sliding capability, improve travelling comfort and the reliability of steering operation.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is that the present invention turns to jack shaft organigram.
Fig. 2 is the sectional view along A-A in Fig. 1.
Fig. 3 is the sectional view along B-B in Fig. 1.
Fig. 4 is that the present invention turns to jack shaft exploded perspective view.
In figure: 1. splined sleeve, 2. splined shaft, 3. spline boot, 4. grease storage groove, 5. universal-joint fork, 6. gas permeability blanking cover, 7. seal ring.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 to 4, one turns to jack shaft, comprise the splined sleeve 1 by spline fitted and splined shaft 2, the other end that splined sleeve 1 and splined shaft 2 match all is welded with universal-joint fork 5, splined sleeve 1 and splined shaft 2 cooperation place are arranged with spline boot 3, are press-fitted the grease storage groove 4 being full of grease in spline boot 3 one end.There is provided enough oiling agents by grease storage groove 4, ensure the reliability of the long-term lubrication between splined sleeve and splined shaft.Effectively can be avoided because workshop assembling or logistics transportation cause splined shaft to be separated with splined sleeve by this spline boot, and produce torque fluctuations when again causing car load to turn to phase angle mistake after the two assembling, affect client's driving comfortability.Wherein, be produce torque fluctuations when avoiding universal joint transmitting torque to be provided with certain angle during two universal-joint fork designs.
Further, be provided with gas permeability blanking cover 6 in the outer end of splined sleeve 1, avoid forming vacuum in splined sleeve by gas permeability blanking cover 6, make it have good sliding capability, improve travelling comfort and the reliability of steering operation.Preferably, gas permeability blanking cover 6 is nylon washer, and cost is low.
Further, in spline boot 3, be provided with seal ring 7, the corresponding splined sleeve end of seal ring 7.Preferably, seal ring is rubber seal, and its internal diameter of the seal ring is less than the external diameter of splined shaft, and sealing effect is good.
Preferably, the excircle of splined sleeve 1 is provided with circular groove with spline boot cooperation place, has rubber ring in circular groove inner sleeve, improve sealing effect.
During assembling, first spline boot, grease storage groove, seal ring can be assembled into component cover, then component cover is coordinated with splined shaft, after cleaning, lubricating grease be coated by component cover, then is combined together with splined sleeve, easy to assembly, no-float.There is good greasy property and sliding capability, effectively avoid the generation of torque fluctuations during car load steering operation, improve travelling comfort and the reliability of steering operation.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technological scheme is carried out; or design of the present invention and technological scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
