Embodiment
[0024] In the present invention, the steering valve is arranged at the rear of the transmission (the side where the torque converter is located is the front, the same below). Among transmission failures, control valve failures account for a large proportion. In the layout of the whole vehicle, there is a large space at the rear of the transmission, and the control valve is arranged at the rear of the transmission, which is more convenient for maintenance.
[0025] In the present invention, the oil suction pipe of the oil pump is arranged inside the transmission (see figure 1 ), to beautify the appearance of the transmission.
[0026] The present invention can cancel the external hose that affects the appearance and is easy to be damaged, or the internal steel pipe that is not suitable for mass production, and integrates the oil pump output, clutch control pressure oil, lubricating oil, etc. into the large end cover.
[0027] The rear part of the hydraulic transmission is the...

The invention discloses an oil way system of a multi-gear hydrodynamic transmission. The hydrodynamic transmission is formed by a torque converter and a power gearshift gearbox, an operation valve is distributed on the rear portion of the transmission, a big end cover is arranged on the rear portion of the transmission, an oil way is arranged on the big end cover which is allocated with a matched transition plate and a matched partition plate, an oil pump inlet and outlet oil ways, clutch control oil ways and lubricating oil ways are at least integrated on the big end cover, an oil pump oil suction pipe is arranged in the transmission, a plurality of clutch control oil ways corresponding to a plurality of clutches are arranged on the big end cover, clutch control oil way holes corresponding to the clutch control oil ways are arranged on the allocated transition plate and the partition plate respectively, the oil pump inlet and outlet oil ways on the big end cover include an oil pump oil suction way and an oil pump oil outlet way, and lubricating oil holes corresponding to the lubricating oil ways are arranged on the transition plate and the partition plate respectively. The oil way system of the multi-gear hydrodynamic transmission is reasonable in structure, convenient and reliable to use, lower in manufacturing cost, capable of greatly improving maintainability of the operation valve, and the like.
Description
technical field [0001] The invention relates to an oil circuit system of a multi-gear hydraulic transmission, which belongs to the technical field of hydraulic transmissions for engineering machinery. Background technique [0002] The hydraulic transmission is composed of a torque converter and a power shift gearbox. The function of power shift (power shift refers to shifting gears under the condition of power transmission, in short, shifting without stopping) is through several sets of wet Multi-plate friction clutches are combined and disconnected according to certain rules; the control system of the hydraulic transmission is composed of an oil pump, a control valve, and an oil circuit system. [0003] The oil circuit system realizes the following functions: ensuring the oil pump in and out, introducing the pressure oil pumped out of the oil pump into the control valve, and introducing the gear position control pressure oil and torque converter working oil into each ...
