Description

[Detailed Description of the Invention] This invention relates to a mounting structure for an oil level gauge for checking the oil level in an oil reservoir of a power steering, automatic transmission, or the like.

FIG. 1 shows a conventionally known oil reservoir tank 1 for power steering, and this oil reservoir tank 1 is integrally constructed with an oil pump 2. As shown in FIG. Reserve oil for power steering is stored in an oil reservoir tank 1, and the suitability of this reserve oil amount is generally checked using an oil level gauge 3. The mounting structure of the oil level gauge 3 is such that the upper end of the oil level gauge 3 is directly fixed to the bottom surface of the cap 4, as shown in Fig. 2. A display section 5 indicating the range is provided. but,
When the reservoir oil amount is small relative to the system oil amount, such as in power steering, the oil level in the oil reservoir tank 1 changes greatly depending on the oil temperature, so the display section 5 also differs from the display section 5a when it is cold and when it is warm. The hour display section 5b is set and displayed separately.

Therefore, in the conventional structure described above, it is very inconvenient to check the oil temperature every time the oil level is checked, and the oil temperature is displayed on the display when the oil temperature is set for cold and warm times. At times other than temperature, the appropriate oil level range is unknown and the oil level inspection must be inaccurate.

This invention was made in order to solve the above-mentioned conventional problems, and its purpose is to make it possible to easily check the oil level without checking the oil temperature.

According to this invention, this object is characterized in that an oil level gauge indicating the appropriate oil amount range is attached via a bimetal, and the oil level gauge is displaced relative to the oil surface in response to changes in oil temperature. This is achieved by the oil level gauge mounting structure.

Next, an embodiment based on the configuration of this invention described above will be described based on the drawings.

FIG. 3 shows an embodiment of this invention, in which an oil level gauge 3 is attached at its upper end to the side of a cap 4 of an oil reservoir tank 1 via a bimetal 6.

With this structure, the bimetal 6 attached to the upper end of the oil level gauge 3 is displaced up and down in the diagram according to changes in oil temperature, and accordingly, the oil level gauge 3 is also displaced up and down with respect to the oil surface. Moving. This bimetal 6 is displaced downward when the temperature is low, and displaced upward when the temperature is high. Therefore, the oil level indicator 5 provided at the bottom of the oil level gauge 3 is in a relatively low position because the oil level gauge 3 is displaced downward when the oil temperature is low. When the temperature rises, the oil level gauge 3 also moves upward accordingly, reaching a relatively high position and indicating an appropriate position according to the oil temperature.

FIG. 4 shows another embodiment, in which an oil level gauge 3 is attached at its lower end to the lower surface of the oil reservoir tank 1 via a bimetal 6, and the operation of the bimetal 6 can be made more accurate. It is placed in oil for this purpose. Its operation is basically the same as that of the previous embodiment, so a description thereof will be omitted.

As described in detail above, this invention attaches the oil level gauge 3 via the bimetal 6, and changes the oil level display section up and down according to the oil temperature, so that the oil level display section always displays the appropriate oil level at that oil temperature state. Because of this, there is no need to check the oil temperature every time the oil temperature is inspected, unlike in the past, and the excellent effect of being able to quickly and accurately check whether the oil level is appropriate or not is achieved. Further, conventionally, it was necessary to set two types of oil level display sections for cold and warm times, but with this invention, only a single display section is required.
