Embodiment Construction

[0029] Aspects of the invention will now be described more fully. Like numbers refer to like elements throughout. Known functions or constructions are not necessarily described in detail for brevity and / or clarity.

[0030] figure 1 A retarder arrangement 1 according to some embodiments is schematically shown. The retarder arrangement 1 is configured to brake the rotation of an axle 3 of the vehicle. The retarder arrangement 1 comprises a retarder rotor 7 and a retarder stator 8 which together form a working space 10 . According to the illustrated embodiment, the retarder arrangement 1 is a hydrodynamic retarder arrangement 1 . The working space 10 is arranged to be filled with a working medium, such as oil or an aqueous mixture, via a retarder duct. Retarder pipe is not in figure 1 shown in . The viscous drag of the working medium in the working space 10 creates a braking torque on the rotor shaft 12 connected to the rotor 7 .

Abstract

A retarder arrangement (1) is disclosed configured to brake rotation of a shaft (3) of a vehicle (5). The retarder arrangement (1) comprises a retarder rotor (7), a retarder transmission (9), a lubricant feed conduit (11) arranged to conduct lubricant to the retarder transmission (9), a coupling device (13), and an actuator element (15). The actuator element (15) is moveable between an actuated position and an unactuated position to move the coupling device (13) between an engaged state and a disengaged state. The coupling device (13) is configured to, in the engaged state, connect the retarder rotor (7) to the shaft (3) via the retarder transmission (9), and in the disengaged state, disconnect the retarder rotor (7) from the shaft (3). The lubricant feed conduit (11) comprises a valve (17) mechanically connected to the actuator element (15). The present disclosure further relates to a transmission arrangement (40), a power train (50), and a vehicle (5).

Description

technical field [0001] The present disclosure relates to a retarder arrangement configured to brake rotation of an axle of a vehicle. The present disclosure also relates to a transmission arrangement for a vehicle, wherein the transmission arrangement comprises a gearbox and a retarder arrangement. Furthermore, the present disclosure relates to a powertrain including a transmission arrangement, and a vehicle including a retarder arrangement. Background technique [0002] A retarder is a device used on a vehicle to augment or replace some of the functions of a primary braking arrangement, such as a friction-based braking arrangement. There are several types of retarders. One common type of retarder is the hydraulic retarder. This type of retarder utilizes the viscous resistance of the fluid in the working space between the rotor and the stator. The rotor is often connected, via a retarder drive, to a shaft of the vehicle, such as a shaft of the vehicle's gearbox. Traditi...
