Abstract
The invention discloses a bearing lubrication structure for an output shaft of an automatic transmission. The structure comprises a hollow output shaft, wherein the output shaft is provided with a first end and a second end and is used for supporting a pair of bearings at the two ends of the output shaft; the bearings are fixed in a transmission shell; an oil baffle plate is arranged at the first end of the output shaft; a first gap is formed between the oil baffle plate and the first end of the output shaft; a second gap is formed between the second end of the output shaft and the wall of the shell; and the hollow part of the output shaft is communicated with the first gap and the second gap to form lubrication channels of the bearings. Due to the adoption of the bearing lubrication structure of the output shaft of the automatic transmission, machining processes can be reduced, an installation process can be simplified and production cost can be reduced.
Description
Technical field
The present invention relates to a kind of bearing lubrication structure, particularly be used for the lubricating structure of the automatic transmission output shaft bearing of automobile.
Background technique
In the prior art, for the spring bearing that is positioned at automatic gearbox output shaft two ends, usually adopt lubricated in such a way: before assembling, on the output shaft of hollow, get earlier the hole that pressure oil can be flowed out, the position of punching is in wants bearings mounted position, when assembling, also need stop and block pressure oil in other words, with the flow direction of guide pressure oil, as shown in Figure 3 at the terminal installation bowl of an output shaft type patch.Though the effect of lubricating bearings preferably can play in this mechanism, its manufacturing procedure is comparatively loaded down with trivial details.For the automatic transmission output shaft, have more two procedures than the processing of common axial workpiece, promptly " punch, press-fit a bowl type patch ".When producing, especially when producing in enormous quantities, quite lose time, cause cost per unit corresponding higher.
Summary of the invention
The objective of the invention is the defective at above-mentioned prior art, a kind of lubricating structure of automatic transmission output shaft bearing is provided, this structure can reduce manufacturing procedure, tubeization mounting process under the prerequisite that can reach same lubrication effect.Adopt the present invention, advantage is more obvious under situation about producing in batches, not only can enhance productivity, and can also reduce production costs under the constant situation of body function.
For achieving the above object, the present invention has adopted following technological scheme:
A kind of lubricating structure of automatic transmission output shaft bearing, the output shaft that comprises a hollow, described output shaft has one first end and one second end, support the pair of bearings at the described two ends of described output shaft, described bearing fixing is in case of transmission, first end at described output shaft is provided with an oil baffle, has first gap between described first end of described oil baffle and described output shaft, has second gap between described second end of described output shaft and the shell body wall, the hollow space of described output shaft is communicated with described first and second gaps, constitutes the lubrication channel of described bearing.Described oil baffle is a bowl-type, and can be the thin-walled stamping part.Described oil baffle can by interference fit be installed in the described housing.Described shell body wall towards described output shaft second end be provided with pyramidal projections.Described second end of described output shaft has a conical bore, the path of described conical bore is the internal diameter of the described hollow space of described output shaft, the big footpath of described conical bore has the gap less than the internal diameter of described bearing inner race between the conical surface of described conical bore and the described pyramidal projections.
The present invention makes improvement to the lubricating structure of prior art, and the punching of bearing matching part, the end at the two ends of automatic transmission output shaft of having cancelled present employing press-fits the design of " bowl type patch ", and tube has been changed processing and assembly technology.By between output shaft and housing, reserving a space, and at this space mounting oil baffle, make lubricated can be when arriving this space according to the lubricant oil trend of design anticipation with pressure oil, output shaft bearing is carried out enforced lubricating, thereby can reduce on the automatic transmission output shaft processing and the installation procedure that punch, install parts such as " bowl type patches ", reduce processing cost effectively, and can improve the working life of output shaft and bearing.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing, but not as a limitation of the invention.
As illustrated in fig. 1 and 2, a pair of tapered roller bearing 3 is installed in automatic gearbox housing 1, these two bearings are supporting the two ends of automatic transmission output shaft 4 respectively, output shaft 4 is for having the hollow structure of through hole along axial direction, lubricant oil can be from wherein passing through, between end of output shaft 4 and housing, reserve a space, an oil baffle 2 is set in this space, and make between this oil baffle 2 and output shaft 4 these end faces and have a gap, when lubricated can be when arriving this space according to the lubricant oil trend of design anticipation with pressure oil, bearing 3 is carried out enforced lubricating, also be reserved with the space that lubricant oil can pass through between the other end of output shaft 4 and the shell body wall, shell body wall is provided with pyramidal projections towards this axle head, so, correspondingly this end at output shaft 4 is provided with a conical bore, the path that makes this conical bore is the internal diameter of the hollow space of output shaft 4, big footpath is less than the internal diameter of bearing inner race, and make and form the gap that lubricant oil can pass through between the conical surface of this conical bore and this pyramidal projections, the hollow space of output shaft 4 is communicated with described two gaps, constitute the lubrication passages of bearing 3, lubricatedly be lubricated with the bearing 3 of the flow direction of pressure oil shown in dash-dot arrows among Fig. 1 to output shaft 4 two ends.Oil baffle 2 can by interference fit be installed in the described housing 1, also can adopt other known mode to be fixed in the housing.The shape of oil baffle 2 can be made and the similar bowl-type of bowl type patch, and its structure is the thin-walled stamping part, also can be the thin walled structures of other form.
Above-described embodiment, just this bright more preferably concrete mode of execution is a kind of, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replace and all should be included in protection scope of the present invention.
