Abstract
The present invention relates to a kind of car steering tube column power transmission shaft, including upper power transmission shaft and lower drive shaft, lower drive shaft puts in power transmission shaft, can be coated with lubricating grease in the inner chamber of upper power transmission shaft relative to upper propeller shaft slip.Its improvement is, stop collar is housed in the close lower end position of lower drive shaft, the stop collar is a single piece, it is made up of upper and lower two opening annulus and upper and lower two annulus openends, two vertical bars of connection, the internal diameter of the upper power transmission shaft that the opening annulus external diameter is more than, limitation lower drive shaft is fully retracted in power transmission shaft, and the opening annulus is provided with reduction breach with the junction of vertical bar, when needing crumple beneficial to steering column power transmission shaft, stop collar disconnects from indentation, there.The present invention increases limiting component by power transmission shaft, prevents steering column power transmission shaft lubricating grease during installation from leaking outside, and ensure not influenceing the crumple of steering column power transmission shaft.
Description
Technical field
The present invention relates to automobile steering system technical field, more particularly to steering column driving-shaft assembly.
Background technology
The steering column power transmission shaft of current automobile will in order to meet national legislation collision and field worker property easy for installation
Ask, use adjustable structure type, i.e. lower drive shaft more steering column power transmission shaft（2）Power transmission shaft can relatively be gone up（1）Slide, such as
Shown in Fig. 1.To reduce upper power transmission shaft（1）And lower drive shaft（2）Between abrasion, upper power transmission shaft（1）Appropriate profit is smeared in inner chamber
Consistent lubricant.
In the installation process of steering column power transmission shaft, workman is needed lower drive shaft（2）Power transmission shaft in indentation（1）, then
By lower drive shaft（2）From upper power transmission shaft（1）Pull out.Due to lower drive shaft（2）There is no position-limit mechanism, process of the workman in operation
In, often by lower drive shaft（2）Power transmission shaft in indentation（1）Length it is long so that be coated in power transmission shaft（1）Lubricating grease from upper
Power transmission shaft（1）End is overflowed, and causes steering column power transmission shaft because lacking lubricating grease and excessive wear, shortens the life-span.
The content of the invention
It is an object of the invention to provide a kind of car steering tube column power transmission shaft, limiting component is increased by power transmission shaft, prevented
Only steering column power transmission shaft lubricating grease leakage during installation, and ensure not influenceing the crumple of steering column power transmission shaft.
Technical scheme is as follows：
A kind of car steering tube column power transmission shaft, including upper power transmission shaft and lower drive shaft, lower drive shaft put in power transmission shaft, can
Relative to upper propeller shaft slip, lubricating grease is coated with the inner chamber of upper power transmission shaft.Its improvement is, in being close to for lower drive shaft
Lower end position is equipped with stop collar, and the stop collar is a single piece, by upper and lower two opening annulus and upper and lower two circles of connection
The vertical bar composition of ring openend two, the internal diameter of the upper power transmission shaft that the opening annulus external diameter is more than, limitation lower drive shaft is complete
In indentation in power transmission shaft, the opening annulus is provided with reduction breach with the junction of vertical bar, is needed beneficial to steering column power transmission shaft
When wanting crumple, stop collar disconnects from indentation, there.
The present invention is arranged on lower drive shaft by designing a stop collar, plays the position-limiting action to down tube axle, is prevented
Workman is long and cause lubricating grease to leak outside due to lower drive shaft to be retracted the length of power transmission shaft in installation process, and extension is turned to
The tubing string power transmission shaft life-span.Meanwhile, using opening circular ring structure, stop collar can be made easily and reliably to be fastened on lower drive shaft, it is right
Power transmission shaft structure in itself is not changed, without prejudice to its original function.In addition, the key position in stop collar devises reduction
Breach so that when vehicle collides, stop collar can be destroyed rapidly, prevent it from hindering steering column power transmission shaft crumple.
Brief description of the drawings
Fig. 1 is existing steering column transmission shaft structure figure.
Fig. 2 is the axonometric drawing of the stop collar that the present invention is used.
Fig. 3 is the structure chart of the steering column power transmission shaft of present invention design.
Specific embodiment
The invention is further described below in conjunction with the accompanying drawings.
Referring to Fig. 3, car steering tube column power transmission shaft includes upper power transmission shaft 1, lower drive shaft 2, and lower drive shaft 2 puts in transmission
In axle 1, can be slided relative to upper power transmission shaft 1, lubricating grease is coated with the inner chamber of upper power transmission shaft 1.In being close to for lower drive shaft
Lower end position is equipped with stop collar 3.
Referring to Fig. 2, the stop collar is a unitary plastic part, and using Shooting Technique is integrally formed, material is thick consistent, its by
Two vertical bars 32 of upper and lower two opening annulus 31 and the upper and lower two annulus opening portions of connection are constituted, and are existed to increase stop collar 3
The convenience of assembly manipulation in lower axle 2 is turned to, 270 degree of the angle requirement of dehiscing of the annulus 31 that is open, 10 degree of upper and lower deviation requirement leads to
Cross the effect of upper and lower two openings annulus, it is convenient to be fastened on lower drive shaft 2.The opening annulus external diameter is greater than upload
The internal diameter of moving axis, can so limit lower drive shaft and be fully retracted in power transmission shaft, annulus 31 and the vertical bar 32 of being open
Junction is provided with reduction breach 33, has four breach, and effect is that, when vehicle collides, stop collar 3 can be from reduction breach
Disconnected at 33, it is rapid destroyed, prevent it from hindering steering column power transmission shaft crumple.
Stop collar 3 is directed at lower drive shaft 2 during assembling, stop collar 3 is firmly pressed into lower drive shaft 2, installed very
It is convenient.
The present invention is prevented from workman during operation, and the length that lower drive shaft 2 is retracted into upper power transmission shaft 1 is long,
So that the lubricating grease for being coated in power transmission shaft 1 overflows from end, steering column power transmission shaft is caused to shorten the longevity because lacking lubricating grease
The problem of life occurs.
