JPS5832059B2 - Installation structure of oil reservoir tank on vehicle - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an oil reservoir tank used in brake and clutch mask cylinders of vehicles such as cab-over trucks, buses, and panzers, and its attachment to vehicle instrument panels.

The oil reservoir tank, which is generally used for the brakes of this type of vehicle, is structurally installed near the back of the instrument panel in the front panel, so it is necessary to fill the tank with oil or periodically fill it with oil. It was extremely inconvenient to check the oil level.

Therefore, in order to improve serviceability during oil injection and to facilitate inspection of the oil level, a service hole is provided in the pad at the top of the instrument panel for oil injection and inspection.

However, in this case, the oil level had to be checked from above the reservoir tank, making it difficult to accurately check the oil level.

An object of the present invention is to provide an oil reservoir tank mounting structure that allows convenient oil injection, accurate oil level inspection, and stable support of the oil reservoir tank.

The present invention will be explained below with reference to the embodiments shown in the drawings. In FIG. 1, a mask cylinder 2 is provided inside the front of the vehicle body, which is closed by a front panel 1, and is connected to a brake pedal 3 in the driver's cab by a bushing rod 4. , there is an instrument panel 6 following the pad 5 above the mask cylinder 2, and the oil reservoir tank 10 of the present invention is attached to the front part of the instrument panel 6.

As shown in FIG. 2, the oil reservoir tank 10 has a main body 11 made of a blow-molded resin (for example, polypropylene) that satisfies necessary properties such as brake oil resistance, heat resistance, cold resistance, and impact resistance, and is transparent. An oil inlet 12 is provided on the side of the main body 11 that projects diagonally from the upper blade, and a breather plug 1 is provided at an appropriate position on the main body 11.
3 and a connecting port 14 are provided, and a cap 16 is attached to the oil inlet 12 incorporating a backing 15 for preventing oil leakage.

When the oil reservoir tank 10 configured in this way is installed on an instrument panel, a hole 17 is drilled in a part of the instrument panel 6 and a rib is provided at the bottom of the hole 17, as shown in FIGS. 1 and 3. 18 is provided, and the main body 11 is lowered on the rib 18 so that the oil inlet 12 and the neck portion 19 of the main body 11, which serves as an oil level display section following the oil inlet 12, are exposed to the outside from the instrument panel surface. The front part is held down by a mounting member 20 as a prevention member to prevent it from jumping out forward, and the rear part is pushed backward by a spring 22 wound around a pin 21. It is held and fixed so that it does not fall off.

In addition, in this mounting position, the oil reservoir tank 10 is connected to the mask cylinder 2 with the connecting port 14 using a rubber bridge tube 23 and a clamp 24 to prevent oil leakage.

In this way, brake oil can be easily injected from the driver's cab by removing the cap 16, and the oil level in the tank 10 can be directly viewed from the instrument panel 6 to easily check the oil amount at any time.

As described above, according to the present invention, the serviceability of oil injection into the oil reservoir tank is improved, and the oil level in the oil reservoir tank can be monitored at the side of the oil reservoir tank, that is, at almost the same height as the oil surface. Since it can be placed and inspected, the oil level can be checked accurately and easily.

In addition, MAX and MIN are marked on the externally exposed part of the tank body.
Inspection becomes even easier by attaching a mark such as the following to use as a guide for checking the oil level.

Furthermore, according to the present invention, since the oil reservoir tank is mounted and supported on the rib that is integrated with the instrument panel, support in the vertical force direction is stable, and the spring and removal prevention member (installation member) Since it is supported in the front-rear direction without any looseness, the support in the front-rear direction becomes stable.
