Abstract

The invention discloses a land leveler transmission system and a land leveler. The land leveler transmission system comprises a power source, a hydraulic pump, a hydraulic motor, an axle, a left wheel and a right wheel. The left wheel is mounted on the left side of the axle, and the right wheel is mounted on the right side of the axle. The power source is connected with the hydraulic pump. The hydraulic pump is connected with the hydraulic motor through a hydraulic oil way. The hydraulic motor is connected with the axle. The axle comprises a left half axle and a right half axle. The left half axle is connected with a left planetary reducer. The right half axle is connected with a right planetary reducer. The left wheel is mounted on the left planetary reducer. The right wheel is mounted on the right planetary reducer. The power transmission path of the land leveler transmission system is short, a gearbox and a balance box are omitted, structural arrangement is compact, and manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a motor grader transmission system and a motor grader. Background technique [0002] A motor grader is a self-propelled wheeled earthmoving machine, which uses scrapers installed between the front and rear axles of the machine and various other auxiliary operating devices for shaping and leveling operations in earthworks. The grader is a high-speed, high-efficiency, high-precision and multi-purpose construction machine, which is widely used in large-scale ground construction such as roads, farmland, and airports. The main operations include ground leveling, trenching, scraping, and bulldozing It is an indispensable and important machine in the construction of the national economy. [0003] At present, the power transmission route of the motor grader driving system is basically divided into four schemes. The first scheme is the power transmission route: engine-gearbox-drive a...
