Abstract
The invention relates to transmission shafts in vehicle parts, particularly to a shaft sleeve type cross shaft. The shaft sleeve type cross shaft comprises a cross shaft frame; a cross oil channel and an oil inlet channel are formed in the cross shaft frame; the oil inlet channel is communicated with the cross oil channel; sealing rings, shaft sleeves and shaft sleeve seats sleeve four shaft heads respectively. The shaft sleeve type cross shaft is characterized in that the rear end of every shaft head is provided with a stop shaft shoulder; the front end of every shaft head is of a step structure; the inner circle surfaces of the shaft sleeves are provided with a plurality of oil grooves; the sealing rings abut against the stop shaft shoulders of the shaft heads; the shaft sleeves and the shaft heads are assembled separately; the shaft sleeves and the shaft sleeve seats are assembled in an interference mode; the shaft sleeve seats and the shaft head step surfaces form oil storage chambers; the oil grooves formed in the shaft sleeves are communicated with the oil storage chambers. The shaft sleeve type cross shaft has the advantages of being simple in structure, convenient to install, good in lubrication effect, free of abnormal noise and abrasion, abrasion-resistant and durable and suitable for improvement of transmission shaft universal joints of various vehicle models.
Description
Technical field
The transmission shaft of the present invention and vehicle component, especially a kind of axle sleeve type cross axle.
Background technique
Universal-joint cross trunnion in existing vehicle, its structure is the form of assembling needle bearing and bearing support on four spindle noses of spider, and bearing support is two sections of separable assembled structural types, its shortcoming is complex structure, inconvenience is installed, and easily wearing and tearing, need often filling butter to lubricate.
Summary of the invention
It is complicated that object of the present invention will overcome existing transmission cross axle structure exactly, and inconvenience is installed, and easily wearing and tearing often need the problems such as filling butter lubricates that a kind of novel axle sleeve type cross axle is provided.
Concrete scheme of the present invention is: for existing cross axle, improve, it has spider, in spider, have cross oil duct, and in spider, have oil input channel and be communicated with cross oil duct, on four spindle noses, be all set with separately seal ring, axle sleeve and sleeve block, it is characterized in that: in the rear end of each spindle nose, be provided with the backstop shaft shoulder, spindle nose front end is ledge structure, at the inner headed face of axle sleeve, have some oil grooves; Described seal ring withstands the backstop shaft shoulder of spindle nose and installs, described axle sleeve and the assembling of spindle nose gap, and axle sleeve and sleeve block interference assembling, sleeve block and spindle nose step surface form accumulator, and the oil groove on described axle sleeve forms and is communicated with accumulator.
Sleeve block outer wall hypomere described in the present invention is provided with tiny step surface, and shoulder height is 0.5mm, and sleeve block inwall upper end is provided with interior step, and interior shoulder height is 0.5mm, and interior step end face withstands end face of shaft bush and installs; And the reduced diameter section length of sleeve block inwall equals the reduced diameter section length of spindle nose front end.
The backstop of spindle nose described in the present invention shaft shoulder outside diameter≤seal ring with outer diameter.
Seal ring described in the present invention adopts damping seal ring.
Sleeve block described in the present invention is monolithic construction.
On spider described in the present invention, have some oil grooves on the front end of each spindle nose, this oil groove is communicated with accumulator.
The present invention, owing to having set up accumulator, makes to remain good lubricating status between axle sleeve and cross axle, wear-resisting durable, the working life of having improved cross axle; And the present invention adopts damping seal ring, sealing effect is good, has no abnormal sound again; That the present invention also has is simple in structure, easy for installation, without features such as frequent charging-up lubricant oils.
Accompanying drawing explanation
Fig. 1 is the main sectional view of the present invention; (in figure, having removed seal ring, axle sleeve, sleeve block on other three spindle noses).
In figure: 1-oil groove, 2-accumulator, step in 3-, 4-axle sleeve, 5-sleeve block, 6-step surface, 7-damping seal ring,
The 8-backstop shaft shoulder, 9-spindle nose, 10-cross oil duct, 11-oil input channel, 12-spider, 13-oil groove, 14-ledge structure.
Embodiment:
Referring to Fig. 1, the present invention has spider 12, in spider 12, have cross oil duct 10, and in spider 12, have oil input channel 11 and be communicated with cross oil ducts 10, on four spindle noses 9, be all set with separately seal ring 7, axle sleeve 4 and sleeve block 5, it is characterized in that: in the rear end of each spindle nose 9, be provided with the backstop shaft shoulder 8, spindle nose front end is ledge structure 14, inner headed face at axle sleeve 4 has the 4 general 3-5 of oil groove 13(roads, road, is no less than 1 road); Described seal ring 7 withstands the backstop shaft shoulder 8 of spindle nose 9 and installs, described axle sleeve 4 and spindle nose 9 gap assemblings, and axle sleeve 4 and sleeve block 5 interference assemblings, sleeve block 5 forms accumulator 2 with spindle nose 9 step surfaces, and the oil groove 13 on described axle sleeve 4 forms and is communicated with accumulator 2.
The 9 backstop shaft shoulder 8 outside diameters≤seal ring 7 outside diameters of spindle nose described in the present embodiment.
Seal ring 7 described in the present embodiment adopts damping seal ring 7.
Described in the present embodiment, on spider, have 5 road oil grooves 13 on the front end of each spindle nose 9, this oil groove 13 is communicated with accumulator 2.
