Embodiment 1

[0014] The combined dynamic load sensing torque amplification conversion device of this embodiment is as follows: figure 2 As shown, it is composed of two parts: torque amplifier (abbreviated as amplifier) ​​and dynamic priority valve. The torque amplifier wherein consists of a fixedly connected valve body 12, a first partition 6, a stator 5, a second partition 4, and an end cover 2 to form a housing member that forms a chamber inside, and the stator 5 is located between the first partition 6 and the second partition. Between the spacers 4, this is more conducive to the formation of an airtight cavity. The shell member is formed with the liquid inlet and the liquid return port and the flow channels communicated therewith. The valve core 4, linkage shaft 9, valve sleeve 8, rotor 7, transmission shaft 3 and output shaft 1 are housed in the chamber. One end of the valve body 12 supports the spool 14 extending to the outside. The inner end of the spool 14 is connected with one e...

Abstract

The invention discloses a combine dynamic load sensitive torque amplifying converter, belonging to the hydraulic transmission technique. Wherein, said device comprises a torque amplifier and a dynamic priority valve; the dynamic priority valve comprises a flow inlet, a flow supply port, a diversion port and a flow channel, while it contains two valve pins that connecting the flow inlet and the flow supply port according to need; or the flow inlet is connected to the flow supply port and the diversion port at the same time; the valve of amplifier has a pressure control valve, a one-way valve and a signal output. When assembling, the flow supply port of dynamic priority valve is through to the inlet of amplifier, while one end of two-way valve pin via flow channel is connected to the signal output of amplifier. The invention can supplies the liquid flow to appointed system, when these systems works together; when appointed system do not work, and it supplies liquid flow to other working system, to distribute the hydraulic energy reasonably; when the system pressure is higher than the pressure of valve, the liquid flow is directly fed to the flux port, without energy consumption, to save energy.

Description

technical field [0001] The invention relates to a dynamic load sensing torque amplification conversion device, in particular to a structural improvement of a combined dynamic load sensing torque amplification conversion device, which belongs to the technical field of hydraulic transmission. Background technique [0002] The torque amplifying device is a hydraulic transmission device commonly used in vehicles. Its basic structure is a shell member that forms a chamber inside the fixedly connected valve body, partition plate, stator, and end cover. The valve core, the linkage shaft, the valve sleeve, the rotor, the transmission shaft and the output shaft are installed in the chamber, and one end of the valve body supports the valve core extending to the outside, and the valve core The inner end of the linkage shaft is connected with one end of the linkage shaft, and the linkage shaft is connected with the valve sleeve installed in the valve body to rotate and switch the flow c...
