Description

Technical Field

[0001] This invention relates to an oil guiding device installed on a carrier component of a vehicle's automatic transmission. Background Technology

[0002] Normally, the fluid inside an automatic transmission will splatter during gear shifts. This splattered fluid is then guided to the pinion shaft by an oil guide device mounted on the transmission's mounting components.

[0003] The load-bearing components of an automatic transmission include a pinion shaft, washers, needle roller bearings, and a pinion. Existing oil guide devices mounted on these components supply spilled oil through the inner diameter (hollow bore) of the pinion shaft to the needle roller bearings. Typically, these existing oil guide devices are manufactured using molded plastic or press-fit sheets.

[0004] However, because the existing oil guiding device has a structure that supplies oil only to the pinion bearing, the remaining oil inevitably scatters and is lost.

[0008] To address the aforementioned problems, the present invention aims to provide an oil guiding device that guides partially spilled oil inside an automatic transmission through a first guide to an oil passage and supplies it to the pinion bearing, while simultaneously providing a second guide to supply the remaining oil to the required components.

[0009] To achieve the aforementioned objective, the present invention provides an oil guiding device, comprising: a main body; an oil passage extending from one side of the main body and connected to an inner diameter portion of a pinion shaft; a first guide member for allowing oil splattered inside an automatic transmission to flow into the inner diameter portion of the oil passage, and configured to surround the inner diameter portion of the oil passage on the other side of the main body; and a second guide member extending from an outer diameter portion of the other side of the main body to surround the first guide member, and guiding any remaining oil not guided to the first guide member to a desired component.

[0010] Furthermore, the second guide includes: a first extension extending from the outer diameter portion of the other side of the main body portion to surround the first guide; and a second extension extending from the first extension portion.

[0011] Furthermore, the first extension forms an acute angle with the first guide.

[0012] Furthermore, the second extension is formed at an angle, bending outward at the boundary with the first extension.

[0013] Furthermore, the boundary between the first extension and the second extension is formed as a circle.

[0014] Moreover, the oil passage is formed in a tubular shape.

[0015] Furthermore, the first guide is formed in an arc shape to surround the inner diameter portion of the oil passage.

[0016] Invention Effects

[0017] The present invention can guide localized oil that has scattered inside the automatic transmission into the oil passage through the first guide member and supply it to the pinion bearing.

[0018] In addition, by providing a second guide extending from the main body, the present invention can supply the remaining oil that is not supplied to the pinion bearing to the required components.

[0019] Furthermore, since the present invention does not require any other device besides the oil guiding device to supply oil to the required components, weight and material costs can be reduced. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. First, it should be noted that when labeling the constituent elements in the drawings, the same symbols are used for the same constituent elements even when they are displayed on different drawings. In describing the present invention, detailed descriptions of related well-known structures or functions are omitted if it is determined that a specific description would obscure the essence of the invention. Furthermore, preferred embodiments of the present invention will be described below; however, the technical spirit of the present invention is not limited thereto, and various modifications can be made by those skilled in the art.

[0025] Figure 1 This is a perspective view of an oil guiding device according to a preferred embodiment of the present invention. Figure 2 This is a diagram showing the state in which the oil guiding device according to a preferred embodiment of the present invention is installed on the carrier. Figure 3 yes Figure 2 An enlarged view of part A.

[0026] like Figures 1 to 3 As shown, the oil guiding device 60 of the present invention can be installed on the carrier 10 of the automatic transmission 1.

[0027] The carrier component 10 assembly of the automatic transmission 1 includes: pinion shaft 30, washer 50, needle roller bearing 20 and pinion 40.

[0028] The present invention includes: a main body 61; an oil passage 63 extending from the side of the main body 61 toward the pinion shaft 30; a first guide 62 extending from the other side of the main body 61 around the inner diameter portion 63a of the oil passage 63; and a second guide 64 extending from the other side of the main body 61 to surround the first guide 62.

[0029] The main body 61 can be formed as a circular plate with an inner diameter portion. The main body 61 can have a predetermined thickness.

[0030] Oil passage 63 is connected to the inner diameter portion of pinion shaft 30. A portion of the oil F1 inside the automatic transmission 1 can flow into oil passage 63 through the first guide 62. The portion of oil F1 flowing into the inner diameter portion 63a of oil passage 63 through the first guide 62 can be supplied to needle roller bearing 20.

[0031] For example, the oil passage 63 can also be formed in a tubular shape. Preferably, there are multiple oil passages 63 so as to be connected to each of the multiple pinion shafts 30.

[0032] The localized oil F1 that is scattered inside the automatic transmission 1 can flow smoothly into the inner diameter portion 63a of the oil passage 63 through the first guide 62.

[0033] The first guide 62 can be used to capture oil and transport it to the inner diameter portion 63a of the oil passage 63. For example, the first guide 62 can be formed as an arc around the inner diameter portion 63a of the oil passage 63. Multiple first guides 62 can be configured to correspond to each of the multiple oil passages 63.

[0034] The second guide 64 is configured to surround the first guide 62. The second guide 64 extends from the outer diameter portion of the other side of the main body 61. The second guide 64 can capture any remaining oil F2 that is not guided to the first guide 62 and deliver it to the desired component.

[0035] Specifically, the second guide 64 includes: a first extension 64a extending from the main body 61; and a second extension 64b extending from the first extension 64a.

[0036] The first extension 64a is formed to extend from the outer diameter of the other side of the main body 61 to surround the first guide 62. The first extension 64a is preferably formed at an angle to form an acute angle with the first guide 62.

[0037] Preferably, the second extension 64b is formed at an angle, curving outward toward the main body 61, so that oil can be supplied to the desired component at the boundary portion 64c with the first extension 64a.

[0038] Preferably, the boundary portion 64c between the first extension 64a and the second extension 64b is machined into a circle. When the boundary portion 64c between the first extension 64a and the second extension 64b is circular, oil can smoothly move from the first extension 64a to the second extension 64b.

[0039] Next, the operation of the oil guiding device according to the present invention will be described.

[0040] The oils F1 and F2 that splatter inside the automatic transmission 1 can, as Figure 2 Move in the direction indicated by the arrow.

[0041] Specifically, the localized oil F1 that has splattered inside the automatic transmission 1 can be guided by the first guide 62, such as... Figure 2 The straight arrow shown moves to oil passage 63.

[0042] Since the oil passage 63 is connected to the inner diameter portion of the pinion shaft 30, the local oil F1 flowing into the inner diameter portion 63a of the oil passage 63 through the first guide 62 can be supplied to the needle roller bearing 20 along the inner diameter portion of the pinion shaft 30.

[0043] By supplying oil to the needle roller bearing 20, the frictional force generated on the friction surface of the needle roller bearing 20 can be reduced, and the frictional heat generated on the friction surface of the needle roller bearing 20 can also be reduced.

[0044] The remaining oil F2 that was not guided to the first guide 62 can pass through the second guide 64, such as... Figure 2 The dashed arrows indicate the supply to the required components.

[0045] Specifically, any remaining oil F2 that is not guided to the first guide 62 can be smoothly supplied to the desired component along the inclined first extension 64a and second extension 64b. Since the boundary portion 64c between the first extension 64a and the second extension 64b is formed in a circular shape, the oil can move smoothly from the first extension 64a along the boundary portion 64c and the second extension 64b.

[0046] When only an oil passage and a first guide are present, only some oil is supplied to the pinion shaft, and the remaining oil that is not captured by the first guide is inevitably lost.

[0047] However, in this invention, since a second guide 64 is provided in addition to the first guide 62, some oil F1 can be supplied to the oil passage 63 through the first guide 62, while the remaining oil F2 not captured by the first guide 64 is captured by the second guide 64 and supplied to the required component. Furthermore, since this invention does not require any other device for supplying oil to the required component besides the oil guiding device, weight and material costs can be reduced.

[0048] The above description is merely illustrative of the technical spirit of the present invention, and those skilled in the art can make various changes and modifications without departing from the essential characteristics of the invention. Therefore, the embodiments disclosed in this invention are not intended to limit but rather to explain the technical spirit of the invention, and the scope of the technical spirit of the invention should not be limited by the above embodiments. The scope of protection of this invention should be interpreted by the appended claims, and all technical spirit within its equivalents should be included within the scope of this invention.
