Abstract

The invention provides a combined hydraulic retarder. The combined hydraulic retarder comprises a power takeoff input gear. The power takeoff input gear is in engaged transmission with a power takeoff gear hub, a spline gear hub is installed on the power takeoff gear hub, a clutch friction plate is installed at the end, close to the power takeoff gear hub, of the spline gear hub, the spline gear hub is fixed to a piston, and the piston communicates through a main oil pressure connector pipeline and is controlled to move. The spline gear hub is coaxially engaged with a transmission retarding assembly, and the retarding assembly is internally and coaxially provided with an electric drive rotating structure composed of a plurality of sets of stators and rotors. According to the combined hydraulic retarder, the combined hydraulic retarder is mounted at a power takeoff port. The combined hydraulic retarder does not interfere with a transmission, can realize a retarding function for the transmission, and is very convenient to mount and dismount; and the combined hydraulic retarder is simple in structure, safe, reliable and easy to disassemble and assemble, the number of rotors and stators can be adjusted according to different vehicle types, the brake requirements of different vehicles can be better met, and manufacturing is easy.

Description

technical field [0001] The invention relates to a combined hydraulic retarder. Background technique [0002] The hydraulic retarder is mainly used on large and heavy vehicles. When the vehicle is on a long downhill section, it acts as a deceleration brake, so that the driver does not have to step on the brake for a long time, which reduces the wear of the brake, improves the safety of driving, and reduces the Driver's labor intensity. Since many transmissions are not equipped with a hydraulic retarder, adding a hydraulic retarder at the end of the transmission requires changing the transmission structure, which increases the difficulty of manufacture and installation. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a combined hydraulic retarder, which can realize the retarding function for the transmission, and is very convenient to install and disassemble. [0004] The present invention is achieved throug...
