A method of controlling a fluid level around a transmission gear of a vehicle includes the steps of providing a set of predetermined operating conditions, each predetermined operating condition having a corresponding predetermined fluid level requirement, operating the vehicle at an actual operating condition, determining a predetermined operating condition equivalent to the actual operating condition, and arranging the fluid level around the transmission gear to be equivalent to the predetermined fluid level requirement corresponding to the predetermined operating condition.

Method of controlling operation of a vehicle

A transmission system includes a housing having a sump, the housing containing a crown wheel and a pinion. The transmission system further includes an oil reservoir and a pump selectively operable to pump fluid from the oil reservoir to the sump for lubricating the crown wheel. The pump is selectively operable to pump fluid from the sump to the reservoir.

Transmission system

An axle assembly including a housing having a first axle tube and a second axle tube, a crown wheel mounted in the housing, a pinion in meshing engagement with the crown wheel, a first reservoir for retaining fluid in contact with the crown wheel for lubricating the crown wheel, a second reservoir for retaining fluid remote from the crown wheel, a first system for transferring fluid in the first reservoir to the second reservoir, a second system for transferring fluid in the second reservoir to the first reservoir, a sensor for generating a signal representative of an axle assembly characteristic, the axle assembly further including a control system for receiving said signal and operating said first system and or said second system to transfer fluid to or from the first reservoir in response to said signal.

Axle assembly

A braking apparatus for a vehicle, in particular a heavy goods vehicle, includes a drive axle having a transmission gear, such as a differential, around which an amount of oil for lubrication is variable. The brake apparatus further includes at least one friction brake and at least one retarder that is capable of operating to slow the vehicle through the transmission gear. The braking apparatus comprises a brake operating device for operating the at least one friction brake and the least one retarder, and a determining feature to determine an oil level around the transmission gear. The brake operating device, on operation by a user, is arranged to apply the retarder when the oil level around the transmission gear is above a threshold level, and, if the oil level is below the threshold level, the brake operating device is arranged to initiate an increase in the oil level around the transmission gear.

Braking apparatus for a vehicle and vehicle comprising said braking apparatus

A transmission system includes a housing having a sump. A crown wheel and pinion are positioned within the housing. The transmission system further includes a reservoir having an inlet system and an outlet system. Rotation of the crown wheel causes the oil to be transferred from the sump to the reservoir via the inlet system, and the outlet system allows oil to pass from the reservoir to the sump.

An axle has a central crown wheel receiving portion with a pinion side and an opposite side. The opposite side is defined by a first crown wheel bowl for receiving a part of a crown wheel, the first crown wheel bowl having a peripheral edge. The axle includes a second crown wheel bowl for receiving the part of the crown wheel. The second crown wheel bowl is nested with the first crown wheel bowl and is attached to the first crown wheel bowl at a peripheral edge to define a reservoir.
