Embodiment Construction
[0013] The present invention will be further described below in two parts according to the embodiment provided by the accompanying drawings.
[0014] The first part, transmission principle.
[0015] When the vehicle is running, the hydraulic retarder ⑶ cooperates with the engine ⑴, hydraulic gearbox ⑵, mechanical gearbox ⑹, hydraulic torque converter ⑺ and each axle gearbox. When the vehicle is driving at high speed, the hydraulic retarder The device ⑶ is in the disengaged state, and the output power of the engine ⑴ is transmitted to the first axle gearbox ⑷ and the second axle gearbox ⑸ through the power unit to drive the vehicle to run. When the vehicle brakes, the power unit is automatically disengaged, and the hydraulic retarder (3) works to generate braking force, which converts the kinetic energy of the vehicle into heat energy through the frictional braking force, thereby reducing the running speed of the vehicle and realizing vehicle speed control.
[0016] The second...

The invention relates to a hydraulic transmission system with a brake retarder. A hydraulic retarder is matched with a transmission component in the following matching forms: the hydraulic retarder is connected in parallel with a single head of a hydraulic transmission box, the hydraulic retarder is connected in series with the single head of the hydraulic transmission box, the hydraulic retarder is connected in series with a single head of a hydraulic torque converter, the hydraulic retarder is connected in series with the far end of an axle gear box, and the hydraulic retarder is connected in series with double heads of the hydraulic transmission box. Various matching forms can be transmitted to the hydraulic retarder through the corresponding axle gear box, and the vehicle speed control is achieved. When the vehicle travels, the hydraulic retarder is matched with the transmission component, when the vehicle travels at a high speed, the hydraulic retarder is in a disengaged state, and an engine outputs power to drive the vehicle to travel through the transmission component. When the vehicle is braked, the transmission component is automatically disengaged, the hydraulic retarder generates braking force, the kinetic energy of the vehicle is converted into heat energy, the running speed of the vehicle is reduced, and the vehicle speed control is achieved. The device has the advantages of being simple in structure, convenient to cooperate, effective in braking and safe in operation.
Description
technical field [0001] The invention relates to the technical field of power transmission and braking of railway vehicles, in particular to a hydraulic transmission system with a brake retarder. Background technique [0002] In the prior art, the braking system of railway vehicles uses a pneumatic brake shoe brake mechanism. The defects of the brake shoe brake mechanism are brake shoe wear, brake shoe overheating and frequent repairs. Such defects will directly increase maintenance. cost and affect driving safety. Contents of the invention [0003] The object of the present invention is to provide a hydraulic transmission system with a brake retarder, which can effectively realize the hydraulic transmission control of the running speed of the railway vehicle and reliably ensure the driving safety of the railway vehicle. The system has unique safety and superiority especially on the long-slope line of the railway. [0004] The technical solution of the present invention i...
