Title:
SINGLE-PUMP-CONTROLLED DUAL-MOTOR MECHANICAL AND HYDRAULIC COMPOSITE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/164048
Kind Code:
A1
Abstract:
A single-pump-controlled dual-motor mechanical and hydraulic composite transmission device, comprising an input member, a planetary gear assembly, an output member, a hydraulic transmission mechanism (6), a power output mechanism (7), a clutch assembly, and a brake assembly. The hydraulic transmission mechanism (6) comprises two constant displacement motors (6-4, 6-7), and the two constant displacement motors (6-4, 6-7) are controlled by a control valve assembly to be connected in series or in parallel. By means of the clutch assembly, the input member is separately connected to the hydraulic transmission mechanism (6) and the planetary gear assembly, the output of one constant displacement motor (6-4, 6-7) is connected to the planetary gear assembly, the output of the other constant displacement motor (6-4, 6-7) is connected to the power output mechanism, and the output member is connected to the planetary gear assembly. The clutch assembly and the brake assembly provide a continuous transmission ratio of the input member to the output member and/or the power output mechanism. This device not only ensures power output, but also has the multi-mode efficient stepless speed change function of a conventional mechanical and hydraulic continuously variable transmission.
