Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] Such as figure 1 As shown, the present invention is preferably a power transmission system, including a prime mover 1, a hydraulic pump 2, a reduction box 5, a drive axle 6, and at least two hydraulic motors 3,4. The prime mover can be an internal combustion engine or an electric motor, etc. The reduction box 5 includes at least two input shafts. The prime mover 1 drives a hydraulic pump 2 , and the hydraulic pump 2 supplies oil to the hydraulic motors 3 and 4 . The output shaft of each hydraulic motor 3 , 4 is connected with each input shaft of the reduction box 5 , and the output shaft of the reduction box 5 is connected with the drive axle 6 . The hydraulic motors 3 and 4 are variable...

Abstract

The invention discloses a power transmission system comprising a reduction box and at least two hydraulic motors. The reduction box comprises at least two input shafts, and an output shaft of each hydraulic motor is connected with each input shaft of the reduction box. The invention further provides a grader comprising the power transmission system. By selection of number of the working hydraulic motors and / or regulation of displacement of the hydraulic motors and / or hydraulic pumps, output speed of the transmission system is changed, and the power transmission system has the advantages of good speed regulation stability, enlargement of speed regulation range and the like.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a power transmission system and a motor grader including the power transmission system. Background technique [0002] At present, the existing motor grader walking power transmission system includes three schemes: (1) prime mover, hydraulic torque converter, gearbox, drive shaft, drive axle, balance box, wheels, (2) prime mover, gearbox, Drive shaft, drive axle, balance box, wheels, (3) For example, CN200420068592 patent discloses a "motor grader driving device", the power transmission route of the patent is: prime mover-hydraulic pump-hydraulic motor-gearbox-drive axle . [0003] Gearboxes are used in the above-mentioned three transmission systems, and the clutch friction plates in the gearboxes are easy to burn out because the gearshift device of the gearbox has high requirements on machinery, hydraulic pressure and control technology. In addition, there will be a certain...
