Description
This i~ventton relates to cooling apparatus for -the vehicle clutch, such as an agricultural -tractor.
In a dry-type clutch used, for example, in an agree-cultural tractor, an air inlet and an air outlet are provided in the clutch housing, so that air can be drawn into the clutch housing to prevent the clutch from overheating. How-ever, in the prior art the air inlet opens outwardly of the vehicle.
A problem arose that dust in the vicinity of the lower portion of the tractor was sometimes drawn into the clutch housing from the air inlet, and this caused clutch trouble and reduced clutching efficiency.
The invention prevents the inhalation of dust into the clutch housing through the air inlet.
According to -the present invention there is provided a cooling apparatus for a clutch of a vehicle, comprising a clutch housing enclosing the clutch and defining an air inlet and an air outlet, said clutch housing being disposed sub Stan-tidally immediately beneath an instrument panel of the vocal and a pipe coupled at one end thereof to said air inlet and opening at another end thereof behind said instrument panel, relative to a front end of said vehicle. Suitably said air inlet is defined at a restricted portion of said clutch house in. Desirably said clutch housing includes a lid removably attached to said air outlet, said air outlet defining a small opening when said lid is attached and a large opening to pro-vise access for inspection when said lid is removed.
In a particular embodiment of the present invention a cooling apparatus for a clutch of a vehicle, comprising a clutch housing enclosing the clutch and defining an air inlet and an air outlet and a pipe connected at one end thereof to said air inlet and opening at another end thereof behind an I
instrument panel of the vehicle relative to a driver's post-lion, said clutch housing being disposed substantially immedi-lately beneath said instrument panel of the vehicle, said air inlet being opened toward a clutch transmission shaft and at least one air outlet being provided opposed to said air inlet across said transmission shaft whereby an axial air flow is generated which surrounds said shaft when said shaft is rotated, said air outlet including a lid removably attached thereto, said air outlet defining a relatively small opening when said lid is attached and defining a relatively large opening to provide access for inspection when said lid is removed.
Since the pipe is connected to the clutch housing at one end and extended into the interior of the vehicle for inhaling at the other end, the inhalation of dust which occurs and floats in the vicinity of the lower portion of the vehicle can be reduced. As a result, clutch trouble and reduction in the clutching efficiency can be avoided. Furthermore, this apparatus can be constructed simply and easily manufactured so that it may be provided at low cost and be advantageous in practical use.
The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings, in which:-- lo -;`3~3~
Fig. 1. is a side view of a clutch cooling apparatus in accordance with the invention;
Fig. 2 is a sectional view ox a portion of an air inlet;
Fig. 3 is a sectional view of a portion of the inhale--lion end of a pipe;
Fig. 4 is a schematic view of a lighting device;
Fig. 5 is a developed perspective view of an essential portion of another embodiment; and Fig. 6 is a sectional elevation of -the essential port lion.
In Fig. 1, numeral 1 shows an agricultural tractor, which comprises an engine 2, a clutch housing 3, and a trays-mission case 4 which are aligned in series to form a vehicle body 5. A radiator, a battery and so forth are mounted on a front wheel axle support frame 6 which is fixed to the engine 2 to project forwardly. Numeral 7 is a hood which covers -the engine 2, -the radiator and so forth. Numeral 8 is a dash board disposed rearwardly of the hood 7. Numeral 9 indicates a pair of front wheels and numeral 10 indicates a pair of rear wheels.
Numeral 11 indicates a pair of fenders which cover the inner sides and the upper sides of the rear wheels 10. Numeral 12 is a steering device which provides a steering handle 13, a steer-in post 14, a steering box and so forth, which device is disk posed to penetrate the front portion of the dash board 8 Verdi-gaily.
A dry-type clutch 18 is housed in the front portion of the clutch housing 3, and an air outlet 19 is provided in -the lower portion of the clutch housing 3 -to face the clutch 18. As shown in Fig. 2, an air inlet 20 is provided a-t a position in -the upper portion of the clutch housing 3 offset rearwardly of the clutch 18. To the air inlet 20, a pipe of tubular shape 23 is connected through a tubular member 22 which penetrates a lid 21 and is secured thereto. The lid 21 is detachably secured to the clutch housing 3 by means of bolts so as to close the air inlet 20. The pipe 23 is fitted onto a projecting end portion of the tubular member 22 and tightened by means of a band 24.
The tip portion of the pipe 23 is extended upwardly and intro-duped into the interior of -the dash board 8.
Numeral 27 is a bracket disposed in the interior of the panel board 8. As shown in Fig. 3, the bracket 27 is secured to a flange 28 of the steering boy 15 by means of bolts to pro-jet forwardly and an inhalation pipe 29 is connected to -the front portion of the bracket 27 to penetrate there through Verdi-gaily. The tip portion of the pipe 23 introduced into -the in-tenor of the dashboard 8 is fitted and tightly secured to the lower portion of the inhalation pipe 29 by means of a band 30.
The upper portion of -the inhalation pipe 29 is bent to make an arc so as to direct an inhalation opening aye of the tip end thereof downwardly. Since the air inlet 20 is communicated with the interior of the dash board 8 through -the pipe 23, there is almost no risk of dust in -the vicinity of -the lower portion of the tractor 1 being inhaled from the air inlet 20 in-to the clutch housing 3 during travel.
Numeral 32 indicates a lighting device standing on -the rear portions of the fenders 11 to face rearwardly. The light-in device 32 is constructed such that a parking lamp and a hazard lamp may be installed selectively in a socket of -the device. AS shown in Fig. 4, the lighting device 32 is connect ted -to an electric source 35, such as a battery, through a swift-eking socket 33 and an on-off switch 34. The switching socket 33 is constructed such that it is possible to change a connecting plug 36, which directly connects both ends of -the switching socket 33, to a hazard unit 37, which actuates an on-and-off operation I
of the hazard lamp installed in -the ligllking device 32, or vice versa. Normally, it it necessary to provide the tractor 1 with a parking lamp or hazard lamp. In this embodiment, i-t is very advantageous to be able -to utilize the lotting device 32 and \ its harness as they are by merely changing -the lamp and the hazard unit 37 to the connecting plug 36 or vice versa.
Although the pipe 23 connected to -the air inlet 20 is introduced in-to the interior of the dash board 8 in this embody-mint, it may be introduced in-to the hood 7 instead.
In another embodiment of -the present invention, an air inlet 120 and an air outlet 119 are disposed separately on each of the sides of the tractor 1. Further, the air inlet 120 is opened at a narrow portion of -the rear clutch housing 103', which is located rearwardly of the air inlet 120. The rear clutch housing 103' and a clutch housing 103 are connected directly -to each other an an air ir~alation as shown by an arrow can directly cool clutch 118. When the clutch 118 rotates, it functions like a centrifugal turbine so as to produce an air flow along a transmission shaft 102. The air inlet 120 is opened at -the squeezed portion of the rear clutch housing 103', and -this means that the air inlet locates close to the trays-mission shaft 102, and therefore a negative pressure occurs at -the air inlet 120 and as the result, the air inhalation effi-Chinese can be increased. Numeral 119' is a detachable lid de-fining an air outlet 119. The air outlet 119 may be utilized as an opening for maintenance by removing -the lid 119'~ Numeral 123 is a pipe which is connected to the air inlet 120 and an inhalation pipe 129 having an inhalation opening aye is connect ted to an upper end -thereof. The inhalation pipe 129 is post--toned in the interior of a dash board 108, as in the first embodiment-, so that dust may not be inhaled. Numeral 101 is a transmission case.
