Abstract

The present invention relates to an auxiliary transmission brake arrangement (100) for a transmission (10) of a vehicle. In particular, the invention relates to an auxiliary transmission brake arrangement comprising a lubrication arrangement for improved lubrication of gear wheels connecting the auxiliary transmission brake arrangement to an output shaft.

Description

technical field [0001] The invention relates to an auxiliary transmission brake device for a transmission of a vehicle. The invention also relates to a corresponding method for controlling such an auxiliary transmission brake arrangement. The invention is applicable to vehicles, particularly light, medium and heavy duty vehicles commonly referred to as trucks. Although the invention will be described primarily in relation to trucks, the invention is also applicable to other types of vehicles. Background technique [0002] On light, medium and heavy duty vehicles, also commonly referred to as trucks, a transmission unit is connected to the prime mover to control the torque load from the prime mover to the propulsion wheels of the truck. Thereby, various ratios between the input shaft and the output shaft of the transmission device can be obtained. [0003] The transmission arrangement may also include an auxiliary transmission brake, also commonly referred to as a retarder...
