Abstract
The invention relates to an autonomous retarder system for a vehicle including a retarder (10) having a central rotor (11) and two stators (12), one on each side of the rotor (11). The rotor (11) is rigidly coupled to an axle (1). A generator (20, 30, 50) is also included, coupled to the retarder (10), for supplying same with electrical energy. In addition, the generator (20, 30, 50) comprises a stator (22) and a rotor (21, 31, 51) coupled to the retarder.
Claims10
An autonomous retarder system for a vehicle that comprises:
- a retarder comprising:
- a central rotor rigidly coupled to an axle, the central rotor having a first side and a second side, the second side being opposite the first side;
- a first stator disposed on the first side of the central rotor, the first stator having a first internal side proximate the central rotor and a first external side opposite the first internal side;
- and
- a second stator disposed on the second side of the central rotor, the second stator having a second internal side proximate the central rotor and a second external side opposite the second internal side;
- a first electromagnet couple attached to the first internal side of the first stator;
- a second electromagnet couple attached to the second internal side of the second stator;
- a first generator secured to the first external side of the first stator of the retarder, the first generator comprising a permanent-magnet generator adapted to supply electrical energy, the first generator further comprising a first generator stator attached to the first external side of the first stator of the retarder, and a first generator rotor different from the central rotor, the first generator rotor disposed on the first external side of the first stator of the retarder, wherein the first generator rotor is rigidly coupled to the axle;
- and
- a second generator secured to the second external side of the second stator of the retarder, the second generator comprising a second generator stator attached to the second external side of the second stator of the retarder, and a winding self-excited generator adapted to supply electrical energy, the second generator further comprising a second generator rotor different from the central rotor and different from the first generator rotor, the second generator rotor disposed on the second external side of the second stator of the retarder, wherein the second generator rotor is rigidly coupled to the axle;
- wherein:
- the first generator and the second generator cooperate such that the first generator supplies electrical energy to the retarder when a rotational speed of the axle is lower than a first threshold and the second generator supplies electrical energy to the retarder when the rotational speed of the axle is higher than a second threshold.
