Abstract
A lubricating oil guiding device for an automotive transmission comprises an oil guiding baffle and an oil guiding groove, wherein the oil guiding baffle is arranged on the inner wall of a case and the oil guiding groove is formed in the inner wall of the case. The oil guiding baffle is located in an oil sling area of a driving shaft assembly, one end of the oil guiding groove is connected with the tail end of the oil guiding baffle, and the other end of the oil guiding groove is connected with a driving shaft oil way. By means of the lubricating oil guiding device, the problem that gaps exist between the oil guiding baffle and the case can be solved effectively, so that oil leakage in an oil guiding mechanism can be avoided.
Description
Technical field
The utility model relates to a kind of device of automotive transmission technical field, specifically is the lubricated oil-guide device of a kind of automotive transmission.
Background technique
Speed changer generally is installed between the clutch and transmission shaft of vehicle, and it is by changing the excursion that velocity ratio enlarges vehicle drive force and speed, to adapt to the driving conditions of frequent variation.Guarantee that the speed changer proper functioning needs the bearing to speed changer inside, component such as gear lubricate fully, at present, this lubricating requirement is more and more higher, the working environment of each grade gear and bearing is also more and more abominable, this not only has higher requirement to the oil product of lubricant oil, and a high request is also had in the design of whole speed changer lubricating structure.
In automotive transmission inside, the engagement driving of gear box internal gear makes the interior temperature of casing rise, so the Oil Guide lubricating structure must be set, reduces gear temperature and lubricated purpose to reach.The Oil Guide lubrication system of traditional speed changer mainly is to adopt split type oil guide plate to finish.
Prior art is carried out literature search to be found, Chinese patent literature CN201215176 day for announcing 2009-4-1, put down in writing a kind of oil-guide device of speed changer lubrication system, comprise that a dishful of shape Oil Guide dish is installed in the groove of case of transmission, be provided with lug boss in the groove of described case of transmission, it is characterized in that: described Oil Guide dish is provided with the breach that matches with the lug boss of groove, the periphery of Oil Guide dish is provided with at least two stopper lever, and case of transmission is provided with the locking groove that matches with described stopper lever.
Chinese patent literature CN202032072U day for announcing 2011-11-09, put down in writing a kind of Oil Guide structure of automotive transmission, be arranged at the defeated oil port of output shaft assembly, comprise the Oil Guide dish that is the video disc shape, described Oil Guide dish middle part offers oil guiding hole, it is characterized in that, the inboard that is positioned at above-mentioned oil guiding hole on the described Oil Guide dish is installed with the oil guide pipe that is communicated with oil guiding hole, the outside that is positioned at above-mentioned oil guiding hole on the described Oil Guide dish is installed with oil trap, and the intracavity inter-connection of oil guiding hole and oil trap.
Though but above-mentioned technology can make the realization of case internal gear reduce temperature and lubricated effect, the gapped appearance of meeting in the process of speed changer work because between housing and the oil guide plate causes Oil Guide efficient to reduce, and makes actual lubrication effect not reach the expection of design.
Summary of the invention
The utility model proposes the lubricated oil-guide device of a kind of automotive transmission at the prior art above shortcomings, can solve the problem that has the gap between oil guide plate and housing, makes Oil Guide in-house oil-proof.
The utility model is achieved through the following technical solutions, the utility model comprises: comprising: the Oil Guide baffle plate and the oil guide slot that are arranged at inner walls, wherein: the Oil Guide baffle plate is positioned at the oily zone of getting rid of of driving shaft assembly, one end of oil guide slot links to each other with the end of Oil Guide baffle plate, and the other end of oil guide slot links to each other with the driving shaft oil circuit.
Described Oil Guide baffle plate is L font structure, comprising: the oil retaining part that is positioned at mounting hole divides and is positioned at the Oil Guide part of transmission case body wall, and wherein: Oil Guide partly is straight plate structure, and Oil Guide baffle plate and housing are that integral type is cast.
Described mounting hole is provided with patch.
Described patch is the column structure of end sealing, and its shape and mounting hole match.
Beneficial effect
Compared with prior art, the utility model plays the effect that Oil Guide is lubricated, cool off the tooth axle, and improves Oil Guide efficient, reduces number of spare parts, improves efficiency of assembling, reduces cost from many aspects, and reduce speed changer overall noise level.

Among the figure: 1 Oil Guide baffle plate, 2 oil guide slot, 3 patches, 4 housings, 5 mounting holes, 6 oil retaining part branches, 7 Oil Guide parts.
Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Shown in Fig. 1 a and Fig. 1 b, present embodiment comprises: the Oil Guide baffle plate 1 and the oil guide slot 2 that are arranged at housing 4 inwalls, wherein: Oil Guide baffle plate 1 is positioned at the oily zone of getting rid of of driving shaft assembly, and an end of oil guide slot 2 links to each other with the end of Oil Guide baffle plate 1, and the other end of oil guide slot 2 links to each other with the driving shaft oil circuit.
Described Oil Guide baffle plate 1 is L font structure, comprising: the oil retaining part that is positioned at mounting hole 5 divides 6 and be positioned at the Oil Guide part 7 of transmission case body wall, and wherein: Oil Guide part 7 be straight plate structure, and Oil Guide baffle plate 1 and housing 4 are that integral type is cast.
Described mounting hole 5 is provided with patch, as shown in Figure 3.Described patch 3 is the column structure of end sealing, and its shape and mounting hole 5 match.
When speed changer is worked, the cyclic process of oil circuit as shown in Figure 4, the driving shaft lubricant oil that is thrown out of that turns clockwise flows to Oil Guide baffle plate 1 at the effect lower edge of gravity shell body wall, the oil guide plate 1 of L type has prevented that lubricant oil from directly flowing out, and make lubricant oil flow into the oilhole that oil guide slot 2 also flows into the driving shaft center again along flow apron 1, thereby the lubricating loop of a beginning new round.Because housing 4 withdrawing patterns restrictions, so will realize being communicated with of Oil Guide baffle plate 1 and oil guide slot 2 by mach mode.Shown in Fig. 2 a and Fig. 2 b, finally seal with patch 3.
