[CN201710299709.X] Loader hydraulic mechanical compound stepless transmission device


[CN201710299709.X] Title of loader hydraulic mechanical compound stepless transmission device: loader hydraulic mechanical compound stepless transmission device application number: CN201710299709.X Applicant: Beijing University of Technology Application Date: 2017-5-2 Patent Type: Invention Application The present invention discloses a loader hydraulic mechanical compound stepless transmission device, which uses hydraulic mechanical section to start and improve low-speed transmission efficiency. The transmission device includes a hydraulic speed control circuit, a CR-CR dividing and converging mechanism, a hydraulic mechanical I-section fixed-axis gear transmission mechanism, a fixed-axis gear transmission mechanism, and a forward and reverse mechanism. Compared with the hydraulic mechanical power shift gearbox of the loader, the present invention can greatly improve the transmission efficiency of the transmission device, and can make the engine often work in the economic speed range, and reduce the fuel consumption and noise level of the loader.
