Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle tank such as an oil reservoir for power steering.

[0002]

[Prior art]

 One of the conventional vehicle tanks is an oil reservoir for power steering. As shown in FIG. 4, the oil reservoir includes a tank body 1 and a baffle 2 provided inside the tank body 1. An injection port 1a is formed in the center of the upper end of the tank body 1 for injecting oil inside. A filter 3 is arranged below the inlet 1a. On the other hand, the baffle 2 has a flat plate shape, and a through hole 2a is formed in the center thereof. The through hole 2a is provided for allowing the oil injected from the injection port 1a to enter the tank body 1 below the baffle 2, and the lower end of the filter 3 is inserted into the through hole 2a.

By the way, when the vehicle vibrates or shakes, the oil in the tank main body 1 swells. In this case, if the baffle 2 is not installed, the oil may scatter and adhere to the inlet 1a, and may leak out from between the inlet 1a and the lid 4. Therefore, the baffle 2 is installed to prevent the oil from splashing and adhering to the inlet 1a as much as possible.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional oil reservoir, it has not been possible to prevent the oil bleeding out to the extent that it is sufficient. That is, the inlet 1a of the tank main body 1 and the through hole 2a of the baffle 2 are arranged vertically opposite to each other in order to inject the oil into the tank main body 1. Therefore, when the oil is greatly undulated, it may be scattered to the inlet 1a through the through hole 2a.

To prevent such a problem, it is necessary to prevent the oil from undulating greatly. However, although the conventional baffle can prevent the oil from scattering, it has hardly been able to prevent the oil from undulating greatly. This is because even if the baffle 2 was installed, the oil was able to move in the horizontal direction, and as a result, the oil was greatly ruffled.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and a tank main body having an injection port formed in the upper part and a substantially horizontal installation inside the tank main body are provided at a position below the injection port. A vehicular tank including a baffle having a through hole is characterized in that a wave stop plate extending downward is formed on a lower surface portion of the baffle.

[0007]

[Action]

 The corrugated plate blocks the horizontal movement of liquid such as oil contained in the tank body. Therefore, the liquid does not swell significantly.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a power steering oil reservoir (vehicle tank) according to the present invention. The oil reservoir 10 includes a tank body 20 and a baffle 30.

The tank body 20 is composed of a lower half body 20A and an upper half body 20B. The lower half 20A is in the shape of a short cylinder, and an annular flange portion 21 protruding outward is formed at the upper end thereof. A bottom portion 22 is formed at the lower end portion of the lower half body 20A. A base 40 for connecting the inside of the tank body 20 to a pump (not shown) is provided at the center of the bottom portion 22.

The upper half body 20B has a shape of a short circle having the same diameter as the lower half body 20A, and an annular flange portion 23 protruding outward is formed at the lower end portion thereof. The upper half body 20B and the lower half body 20A are integrally fixed by abutting the flange portion 23 against the flange 21 via a sealing material 24 such as a gasket, and crimping so as to wrap the flange portion 21. ing. Further, an upper bottom portion 25 is formed at the upper end portion of the upper half body 20B. An injection port 26 is formed in the center of the upper bottom portion 25. The upper end opening 26a of the injection port 26 is projected inward, and is inclined downward toward the inside. The opening 26a is opened and closed by the lid 50.

The baffle 30 is integrally formed of resin and has a disc portion 31, as shown in FIG. The disc portion 31 is for preventing the oil 60 from splashing, and is arranged horizontally slightly above the oil surface of the oil 60. The disc portion 31 is formed with a hole 31a for returning the oil that has entered between the disc portion 31 and the upper bottom portion 25 to a position below the baffle 30.

A cylindrical portion 32 extending downward is formed on the outer peripheral portion of the disc portion 31. The tubular portion 32 is slightly larger than the inner diameter of the tank body 20, and the baffle 30 is fixed to the tank body 20 by press-fitting the tubular portion 32 into the tank body 20. In this case, a notch 32a extending upward is formed in the lower portion of the tubular portion 32 so that the tubular portion 32 can be easily press-fitted into the tank body 20.

A fitting cylinder portion 33 is formed at the center of the disc portion 31. The upper portion of the fitting cylinder portion 33 is oil-tightly fitted to the lower portion of the injection port 26. However, as also shown in FIG. 2, a groove portion 33a extending from the upper end to the central portion is formed on the outer periphery of the fitting tubular portion 33, and air is introduced between the groove portion 33a and the inner periphery of the inlet 26. Air bodies such as the above are circulated in and out of the tank body 20.

The inner periphery of the fitting tubular portion 33 is a through hole 34, and an annular support plate portion 35 is formed at the center of the inner peripheral surface of the through hole 34. A filter 70 is attached to the engagement plate portion 35. The oil injected from the injection port 26 is accommodated in the tank body 20 via the through hole 34 and the filter 70.

On the lower surface of the disc portion 31, a partition cylinder portion (corrugation plate) 36 extending downward is formed. The divided cylindrical portion 36 abuts on the bottom portion 22, so that the internal space of the tank body 20 below the disc portion 31 becomes an annular space 80A outside the divided cylindrical portion 36 and the inside of the divided cylindrical portion 36. Is divided into a central space 80B. However, a notch 36a is formed at an appropriate position on the lower end of the split tubular portion 36, and the spaces 80A and 80B communicate with each other through the notch 36a.

In FIG. 1, reference numeral 90 is a return pipe for returning the oil 60 supplied to the power steering mechanism by the pump into the tank main body 20, and the return pipe 90 is located in the tank main body 20. A strainer 91 is provided at the leading end of the strainer.

In the oil reservoir 10 having the above-described configuration, the internal space for accommodating the oil 60 in the tank body 20 is divided into the two spaces 80A and 80B by the partition tube portion 36, so that the oil 60 in the horizontal direction is Movement is restricted. Therefore, the ripple of the oil 60 can be suppressed to a small level, which can prevent the oil 60 from splashing through the through hole 34 and the filter 70 to the filling port 26 as much as possible. It is possible to reduce or prevent the exudation from 26 to the outside.

In particular, in this embodiment, since the inner circumference of the fitting tubular portion 33 is the through hole 34 and the length thereof is long, the oil 60 is further prevented from being scattered to the inlet 26. be able to. Moreover, since the opening 26a of the injection port 26 projects inward and is inclined downward, even if the oil 60 adheres to the inner peripheral surface of the injection port 26, the oil 60 exudes to the outside. Can be prevented more reliably.

It should be noted that the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the invention. For example, the above-mentioned embodiment applies the present invention to an oil reservoir for power steering, but the present invention can also be applied to other vehicle tanks such as a fuel tank. Although the tank body 20 is formed to have a circular cross section, it may have another shape.

Further, although the partition cylindrical portion 36 having an annular shape is formed as the wave stopping plate, a plurality of wave stopping plates independent of each other may be formed instead of forming the annular forming cylindrical portion 36. Further, a tubular portion (corrugation plate) concentric with the partition tubular portion 36 may be formed inside and / or outside.

[0021]

[Effect of device]

 As described above, according to the vehicular tank of the present invention, since the wave stopper plate extending downward is formed on the lower surface of the baffle, it is possible to prevent the liquid contained in the tank, such as oil or fuel, from significantly waving. It is possible to prevent the liquid from splashing through the through hole to the inlet, and thus preventing the liquid from seeping out from the inlet.
