Patent number: 10399392Abstract: A processor for controlling operation of a central tire inflation system (CTIS) to change a tire pressure of a tire of a vehicle is configured to control the CTIS to inflate or deflate the tire to a predetermined tire pressure which is above a target tire pressure for the tire. The processor then controls the CTIS to deflate the tire until the target tire pressure is reached. In this manner, a second tire inflation operation to achieve the target tire pressure in the tire can be avoided.Type: GrantFiled: April 10, 2015Date of Patent: September 3, 2019Assignee: JAGUAR LAND ROVER LIMITEDInventors: Paul King, Emma-Claire Dunning, Robbie Lesbirel, Maelle Dodu, Thuy-Yung Tran, Laur Läänemets, Jonathan Woodley

Patent number: 10173478Abstract: A filter device for a conduit includes a gas-permeable pre-filter element and a gas-permeable, liquid-impermeable filter element. The filter device is configured to be fluidly coupled to a conduit such that a gas can flow, in sequence, through the pre-filter element, the filter element and then the conduit. The filter device can be used in each of a vehicle hollow driveshaft and a hollow wheel stub axle forming a CV joint having a compressed air supply line which passes therethrough. Compressed air can be supplied via the air supply line without the need for an additional fluid transfer device fluidly connecting the driveshaft and the stub axle's conduits.Type: GrantFiled: September 12, 2014Date of Patent: January 8, 2019Assignee: Jaguar Land Rover LimitedInventors: Emma-Claire Dunning, Edward Hoare, Laur Läänemets, Maelle Dodu, Thuy-Yung Tran

Patent number: 9989102Abstract: A vented gaiter (6) for mounting to a shaft (4) comprises: a rim (34) defining an opening (33) for receiving the shaft (4); and a separate venting element (40). The venting element (40) is disposed within said opening (33). The shaft (4) is received in the opening (33), and the rim (34) is mounted to the shaft by means of a circular clamp (22). The venting element (40) is thus retained in place between the shaft (4) and the rim (34) and allows any air accumulated inside a CV joint enclosure (28) formed by the gaiter (6) when the gaiter (6) is mounted to the shaft (4) to vent axially according to a direction substantially parallel to the shaft longitudinal axis. The venting element (40) comprises a gas-permeable liquid-impermeable membrane (41).Type: GrantFiled: September 12, 2014Date of Patent: June 5, 2018Assignee: Jaguar Land Rover LimitedInventors: Emma-Claire Dunning, Edward Hoare, Laur Läänemets, Maelle Dodu, Thuy-Yung Tran

Patent number: 9878586Abstract: A vehicle wheel assembly (1) for supplying compressed air from a vehicle axle to a tire (3) comprises a vehicle wheel (5) and a control valve assembly (7). The wheel (5) comprises a wheel hub (9) for mounting the wheel (5) to a vehicle (V); and a wheel rim for mounting a tire (3) on the wheel (5). A transfer line (19) is provided in the wheel for transferring compressed air from the wheel hub to the wheel rim (11) for inflating the tire (3). The control valve assembly (7) comprises an inlet, an outlet and a control valve (25) operably located between the inlet and the outlet for controlling passage of compressed air between the inlet and the outlet. The control valve assembly (7) is removably disposed in the wheel hub (9) such that fluid communication is established between the control valve assembly (7) and the transfer line (19).Type: GrantFiled: July 30, 2014Date of Patent: January 30, 2018Assignee: Jaguar Land Rover LimitedInventors: Laur Läänemets, Emma-Claire Dunning, Kit Jones, Maelle Dodu, Mark Ford, Michael Boyd, Daniel Loftus

Patent number: 9845872Abstract: A gaiter (4) for a lubricated joint (1) comprises a sidewall structure (9) defining an enclosure (5) for receiving a lubricant and a passageway (24) for conveying a gas. In use, the passageway (12) conveys gas in isolation from said enclosure (5). Gaiters (4) in accordance with the invention find application in vehicle central tire inflation systems (CTIS).Type: GrantFiled: September 12, 2014Date of Patent: December 19, 2017Assignee: Jaguar Land Rover LimitedInventors: Emma-Claire Dunning, Edward Hoare, Maelle Dodu, Laur Läänemets

Publication number: 20160199768Abstract: A filter device (7, 8) for a conduit (9, 10) comprises a gas-permeable pre-filter element (21, 23) and a gas-permeable, liquid-impermeable filter element (22, 24). The filter device (7, 8) is configured to be fluidly coupled to a conduit (9, 10) such that a gas can be caused to flow, in sequence, through the pre-filter element (21, 23), the filter element (22, 24) and then the conduit (9, 10). Such a filter device (7, 8) can for example be used in each of a vehicle hollow driveshaft (2) and a hollow wheel stub axle (6) forming a CV joint (11) having a compressed air supply line which passes therethrough, as is the case in some central tyre inflation systems (CTISs). Thus, compressed air can be supplied via said air supply line without the need for an additional fluid transfer device fluidly connecting the driveshaft and the stub axle's conduits (9, 10).Type: ApplicationFiled: September 12, 2014Publication date: July 14, 2016Inventors: Emma-Claire DUNNING, Edward HOARE, Laur LÄÄNEMETS, Maelle DODU
