The invention discloses a hydraulic transmission device, which comprises a hydraulic box, a mechanical box, an oil supply lubricating system and an electric control system; and the hydraulic box comprises a hydraulic box shell, an input shaft flange, an input shaft, an input shaft pump gear, an input shaft speed increasing gear, a hydraulic coupler pump wheel, a hydraulic coupler turbine, a hydraulic torque converter pump wheel, a hydraulic torque converter turbine, a hydraulic torque converter shaft gear, a hydraulic torque converter intermediate shaft, a rotor and a stator which are arranged in the hydraulic box shell. The hydraulic transmission device needs a torque converter shaft, is simple in structure, high in braking efficiency, small in size and light in weight, can change the output characteristic of a diesel engine into the ideal traction characteristic close to a locomotive according to the change of the running working condition of the locomotive, and automatically controls corresponding execution elements to work by an electric control system of the hydraulic transmission device, thus stepless speed regulation and automatic direction switching of low-speed starting, high-speed running and hydraulic braking are achieved.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a hydraulic transmission device. Background technique [0002] The hydraulic transmission device is a device used to connect a power source such as an engine or a motor with a working machine to transmit rotational power. It uses liquid as the working medium and uses the kinetic energy of the liquid to achieve energy transmission. The output torque of the hydraulic torque converter can automatically increase or decrease with the increase or decrease of the external load, the speed can automatically decrease or increase accordingly, and stepless speed regulation can be realized in a wide range. It can reduce the number of gears in the transmission of the vehicle, simplify the operation, prevent the flameout of the internal combustion engine, and improve the general performance of the vehicle. The hydraulic coupling has the characteristics of automatic transmissio...
