The invention relates to the technical field of automobiles, and discloses a hydraulic retarder which comprises a retarder shell, and a retarder cover is arranged outside the retarder shell. The working cavity is located in the retarder and connected with the retarder cover; the stator is fixed to the retarder cover through a bolt and located in the working cavity, and a bearing seat is installed on the stator; the rotor is connected with the retarder cover and is positioned in the working cavity; the input shaft is arranged on one side of the working cavity and is connected with the rotor; the flange shaft is axially arranged in the retarder shell in a penetrating manner; an outer ring of the bearing is connected with the bearing seat, an inner ring of the bearing is mounted on the shaft diameter ring, and the shaft diameter ring is axially positioned through the flange shaft; one end of the separating spring is connected with the rotor, and the other end of the separating spring is connected with the spring retainer ring. According to the hydrodynamic retarder, the distance between the stator blade and the rotor blade of the retarder in the non-working state can be increased, and the power loss of a vehicle in the running state is increased and reduced.

    本发明涉及汽车技术领域,公开了一种液力缓速器,包括缓速器壳体,所述缓速器壳体外部设有缓速器盖;工作腔,位于缓速器内部与缓速器盖相连;定子,通过螺栓固定于缓速器盖上且位于所述工作腔内部,所述定子上安装有轴承座;转子,与缓速器盖相连且位于所述工作腔内部;输入轴,设置于所述工作腔一侧并与转子连接;法兰轴,轴向穿设于所述缓速器壳体内;轴承,所述轴承外圈连接轴承座,内圈安装在轴径环上,所述轴径环通过法兰轴进行轴向定位;分离弹簧,所述分离弹簧一端连接转子,另一端连接弹簧挡圈。本发明公开的液力缓速器能够增大缓速器在非工作状态时的定转子叶片距离,增进而降低车辆在运行状态下的功率损失。
