Abstract

A firefighting pump transmission for use with an emergency vehicle pump comprising a housing receiving a drive shaft, the drive shaft having a PTO gear affixed thereto within the housing, an impeller shaft for turning an impeller of a pump, and means for selectively powering the impeller shaft from the drive shaft, the means for powering may include a multi-disk clutch. The transmission allows for powering the PTO gear while the impeller shaft is idle. A Commercially Available PTO device may be mounted to the housing to power a variety of devices.

Claims

received by the International Bureau on 11 July 2008 (11.07.2008). [Claim 1 ] 1 . A firefighting pump transmission comprising:
a PTO gear affixed to a drive shaft, and means for selectively powering an impeller shaft from said drive shaft, said means independent of said PTO gear, said means for selectively powering including a clutch.
[Claim 2] 2. The transmission of claim 1 where said clutch is a multi-disk clutch and where a chuck of said clutch mounts onto said impeller shaft.
[Claim 3] 3. The transmission of claim 1 further comprising a clutch driving gear affixed to said drive shaft and coupled with a clutch gear of said clutch.
[Claim 4] 4. The transmission of claim 3 where said clutch driving gear is affixed adjacent said PTO gear.
[Claim 5] 5. The transmission of claim 1 where said PTO gear is a spur gear.
[Claim 6] 6. The transmission of claim 1 further comprising a PTO device mounted to a housing of said transmission and engaged with said PTO gear.
[Claim 7] 7. The transmission of claim 6 where said PTO device is a Commercially Available PTO device capable of mounting to a casing having mounts satisfying Society of Automotive Engineers Standard SAE J704.
AMENDED SHEET (ARTICLE 19)
[Claim 8] 8. The transmission of claim 6 where said PTO device is mounted to a side of a housing of said transmission and where said transmission further includes a firefighting pump.
[Claim 9] 9. The transmission of claim 6 where said PTO device includes a drive line.
[Claim 1 0] 10. The transmission of claim 6 further comprising a lubrication pump capable of supplying pressured lubricant to said housing.
[Claim 1 1 ] 1 1. The transmission of claim 10 further comprising a radiator to cool the lubricant and at least one filter to filter the lubricant.
[Claim 1 2] 1 2. A firefighting pump transmission comprising: a housing; a PTO gear affixed to a drive shaft within said housing; an impeller shaft; and means for selectively powering said impeller shaft from said drive shaft, said means for powering including a multi-disk clutch independent of said PTO gear.
[Claim 1 3] 1 3. The pump transmission of claim 12 further comprising a port defined by said housing, a mounting face positioned about a perimeter of said port and defining a plane, said plane oriented substantially parallel to a longitudinal axis of said drive shaft.
[Claim 1 4] 14. The pump transmission of clam 1 2 where said PTO gear is a spur gear.
AMENDED SHEET (ARTICLE 19)
18 [Claim 21 ] 21 . A firefighting pump transmission comprising: a PTO gear affixed to a drive shaft;
means for selectively powering an impeller shaft from said drive shaft,
said means for selectively powering including a clutch; and
a clutch driving gear affixed to said drive shaft and coupled with a clutch gear of said clutch.
