Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle clutch cooling device.

[0002]

[Prior Art]

 Generally, in order to reduce the ambient temperature around the clutch of the vehicle, the housing covering the clutch is equipped with a clutch cooling device.

In the clutch cooling device, an air cleaner for introducing air is provided in a part of the housing in which the flywheel and the clutch are covered by a flywheel side housing and a clutch side housing, respectively, and an air cleaner for discharging the air to the other part. A catcher is provided (for example, Japanese Utility Model Laid-Open No. 52-155846).

[0004]

[Problems to be solved by the device]

 However, in the above clutch cooling device, the air catcher is provided in the flywheel side housing in which the gap between the flywheel and the flywheel side housing is narrow, so that the air catcher having a large capacity is not provided. As a result, the ventilation air volume is not sufficient, the life of the clutch disc is shortened, and there is a possibility that the clutch cover is commonly “sent”.

In addition to the air catcher and the air cleaner, the housing is provided with an inspection window for inspecting the clutch. The present invention has been made in consideration of the above, and a clutch cooling device that cools the periphery of the clutch satisfactorily to increase the life and durability of the clutch and allows the clutch to be inspected without providing a separate inspection window. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 According to the present invention, an air cleaner for introducing air is provided in a part of the housing in which the flywheel and the clutch are covered by a flywheel side housing and a clutch side housing, respectively, and an air catcher for discharging the air is provided in another part. In the clutch cooling device, an air catcher is installed in the upper position of both housings, and the air catcher on the clutch side is composed of a large capacity air catcher that doubles as an inspection window. The feature is that an air cleaner is installed in the.

[0007]

[Action]

 If an air cleaner is installed at a location far from the air catchers in the flow direction, the air introduced into the housing will circulate sufficiently around the flywheel and clutch. In addition, a large-capacity air catcher is provided in the clutch-side housing that has plenty of space. Therefore, a sufficient ventilation air volume can be obtained.

Further, the air catcher also serving as the inspection window provided on the clutch side housing eliminates the need to provide a separate inspection window.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the clutch cooling device of the present invention.

In the figure, E is an engine and T is a transmission. A flywheel 1 and a clutch 2 are provided between the engine E and the transmission T. The flywheel 1 is provided with a ring gear 3 on the outer peripheral side and is covered with a flywheel side housing 4. On the other hand, the clutch 2 is covered with a flywheel side housing 4 and a clutch side housing 5.

At upper positions of the flywheel housing 4 and the clutch housing 5, air catchers 6 and 7 are provided to guide the air in the housings 4 and 5 to the outside. The air catcher 6 provided on the flywheel side housing 4 has a small gap between the flywheel 1 and the flywheel side housing 4, so that it has a small capacity as shown in FIG.

The air catcher 7 provided in the clutch-side housing 5 is a large-capacity air catcher because the gap and the distance between the clutch 2 and the clutch-side housing 5 are large.

Further, the air catcher 7 is provided with a bolt hole so that it can be easily removed, so that the clutch 2 can be inspected. An air cleaner 8 for introducing external air into the housings 4 and 5 is provided at a portion far from the air catchers 6 and 7 with respect to the flow.

Then, as the flywheel 1 and the clutch 2 rotate, air is introduced from the air cleaner 8 into the housings 4 and 5 to rotate, and the large wheels provided on the flywheel side housing 4 and the clutch side housing 5 are provided. Derived through the volume air catchers 6,7.

During this time, the flywheel 1, the clutch 2, and the housings 4 and 5 themselves are sufficiently cooled by the air introduced into the housings 4 and 5. Therefore, the wear of the clutch disc facing and the sag of the clutch cover 2 are prevented, and the life and durability are increased.

[0016]

[Effect of the device]

 As described above, according to the present invention, the periphery of the clutch is well cooled to increase the life and durability, and the air catcher provided in the clutch side housing also serves as the inspection window, so that the inspection window is separately provided. It is also possible to obtain the effect that the structure is simple because it is not necessary.
