Abstract
Multi-plate brake or clutch includes a carrier, a fluid dispensing device and plurality of friction plates located around the carrier and the fluid dispensing device. The carrier includes a carrier body, a plurality of external splines located around a rim of the carrier body extending outwardly from the rim, and a passageway that extends through the carrier body to a passageway outlet. The fluid dispensing device includes a body defining a reservoir with an opening in fluid communication with the passageway outlet to allow fluid to be dispensed when a volume of fluid in the reservoir exceeds a predetermined volume.
Claims17
A multi-plate brake or clutch comprising:
- a carrier, the carrier comprising:
- a carrier body;
- and
- a plurality of external splines located around a rim of the carrier body and extending outwardly from an outer surface of the rim that extends between adjacent ones of the plurality of external splines, and wherein the carrier comprises a passageway that extends through the carrier body to a passageway outlet;
- a fluid dispensing device comprising a device body defining a reservoir for collecting fluid and an opening for allowing fluid to be dispensed from the reservoir, wherein the fluid dispensing device is located so that the reservoir is in fluid communication with the passageway outlet via the opening;
- and
- a plurality of friction plates located around the carrier and the fluid dispensing device, wherein the fluid dispensing device is mounted such that the reservoir is located outwardly of the outer surface of the rim and arranged to allow fluid to be dispensed from the reservoir via the opening when a volume of fluid in the reservoir exceeds a predetermined volume.
A multi-plate brake or clutch comprising:
- a carrier, the carrier comprising:
- a carrier body;
- and
- a plurality of external splines located around a rim of the carrier body and extending outwardly from the rim, wherein the carrier comprises a passageway that extends through the carrier body to a passageway outlet;
- a fluid dispensing device comprising a device body defining a reservoir collecting fluid and an opening for allowing fluid to be dispensed from the reservoir, wherein the fluid dispensing device is located so that the reservoir is in fluid communication with the passageway outlet vie the opening;
- and
- a plurality of friction plates located around the carrier and the fluid dispensing device, wherein the fluid dispensing device is arranged to allow fluid to be dispensed from the reservoir via the opening when a volume of fluid in the reservoir exceeds a predetermined volume;
- the fluid dispensing device is one of a plurality of fluid dispensing devices, and wherein the carrier comprises a plurality of corresponding passageways.
A fluid dispensing device for a multi-plate brake or clutch, the multi-plate brake or clutch comprising:
- a carrier, the carrier comprising:
- a carrier body;
- and
- a plurality of external splines located around a rim of the carrier body and extending outwardly from the rim, wherein the carrier comprises a passageway that extends through the carrier body to a passageway outlet;
- a plurality of friction plates located around the carrier,
- and wherein the fluid dispensing device comprises:
- a device body comprising an inner side for locating adjacent to the carrier;
- and
- a reservoir in the device body having an opening in the inner side for positioning adjacent to the passageway outlet and receiving fluid therefrom;
- location means arranged to enable the fluid dispensing device to be located around the carrier so that the reservoir is in fluid communication with the passageway outlet via the opening, and the location means being arranged to enable the fluid dispensing device to move relative to the carrier and be guided by one or more friction plates;
- wherein the fluid dispensing device is arranged to allow fluid to be dispensed from the reservoir via the opening when a volume of fluid in the reservoir exceeds a predetermined volume.
