Embodiment Construction

[0029] Please refer to FIG. 1 , which is a structural diagram of an existing hydraulic motor grader transmission device.

[0030] As can be seen from FIG. 1 , the existing hydraulic motor grader transmission device includes an engine 1 , a hydraulic pump 4 , and hydraulic motors 5 and 6 .

[0031] The engine 1 is used as a prime mover to provide power to the motor grader. The throttle opening of the engine 1 can be adjusted, and different throttle openings correspond to different engine output characteristic curves. Under each throttle opening, the output characteristic curve of the engine includes torque-speed curve, power-speed curve, fuel consumption-speed curve, these curves can provide the relationship between torque, power, fuel consumption and speed of the engine, and the adjustable parameters of the engine are The throttle opening of the engine corresponds to the same throttle opening, and the engine has a corresponding torque-speed curve, power-speed curve, and fuel ...

Abstract

The invention discloses a hydraulic leveler actuator, which comprises a generator (1), a clutch (2), a hydraulic pump (4), hydraulic motors (5, 6) and deceleration balance boxes (8, 9), wherein input shafts of the hydraulic motors (5, 6) are respectively connected to the output end of the hydraulic pump (4), output shafts of the hydraulic motors are respectively connected to input shafts of the deceleration balance boxes (8, 9); output shafts of the deceleration balance boxes(8, 9) are respectively connected to wheels (7, 12, 10, 11). The invention also comprises an acceleration box (3), wherein one end of the acceleration box (3) is connected to the fly wheel shell of the generator (1) through the clutch (2), the other end of the acceleration box is connected to the input end of the hydraulic pump (4); the hydraulic pump (4) is of small output volume and high rotation speed. The hydraulic leveler actuator can lower the generator noise, vibration, oil consumption and discharge, has comfort driving and saves production cost.

Description

technical field [0001] The invention relates to a transmission device for a grader, in particular to a transmission device for a hydraulic grader. Background technique [0002] The grader is a high-speed, high-efficiency, high-precision and multi-purpose earthmoving machinery. It can complete large-area ground leveling, trenching, slope scraping, bulldozing, snow removal, loosening, compaction, cloth, mixing, loading and land reclamation for large areas such as roads and farmland. It is ideal for national defense projects, mine construction, and road construction. , water conservancy construction and farmland improvement and other important equipment in construction. In recent years, the scope of use of motor graders has been expanding; with the continuous development of economic construction and science and technology, people have paid more and more attention to the driving comfort, environmental protection and energy saving of construction machinery. Therefore, the const...
