Series hydrodynamic retarder

Abstract

The invention discloses a series hydrodynamic retarder. The series hydrodynamic retarder comprises a retarder shell, wherein a retarder cover is fixed to the retarder shell through a bolt, a hollow shaft is arranged on the retarder shell and the retarder cover in a penetrating manner, a first oil seal seat ring, a cylindrical roller bearing, an oil return cover plate, a retarder rotor, a retarder stator, a deep groove ball bearing and a second oil seal seat ring are sequentially arranged on the hollow shaft, a first high-pressure oil seal structure and a second high-pressure oil seal structure are respectively arranged on the first oil seal seat ring and the second oil seal seat ring, and a first labyrinth seal structure and a second labyrinth seal structure are respectively arranged on the outer sides of the first high-pressure oil seal structure and the second high-pressure oil seal structure; and an input flange plate and an output flange plate are assembled at the two ends of the hollow shaft, and the input flange plate and the output flange plate are fastened by drag bolts. The retarder can be separated from a transmission rear cover and independently arranged on a transmission shaft system between a second vehicle axle and a driving axle, so that space interference problems are effectively solved.

Description

technical field [0001] The invention belongs to the field of automobile retarders, in particular to a serial hydraulic retarder. Background technique [0002] Long-term use of brake pads for braking will cause huge hidden dangers to the safety of vehicles, and the frequent occurrence of traffic accidents has aroused widespread concern in the society. With the improvement of users' requirements for vehicle braking safety and the introduction of relevant regulations GB7258, the hydraulic retarder has received widespread attention from users and has been fully promoted. The entire vehicle is equipped with a hydraulic retarder as an auxiliary braking device. Has become the development trend of the automotive industry. Matching the hydraulic retarder can greatly reduce the number of times the brake pads are used and improve the driving safety of the vehicle. Hydraulic retarders can be divided into serial hydraulic retarders and parallel hydraulic retarders according to the asse...
