Abstract
The invention discloses a hydrostatic mechanical power diversion transmission gear working fluid composition which uses a natural gas synthetic oil (GTL) / trimethylolpropane ester compound as base oil and is matched with multiple composite additives. The composite additives comprise antiwear additive, rust inhibitor, antioxidant, antifoam agent, demulsifying compound, metal passivator, reinforcing agent, oily agent, friction improver, dispersing agent and the like. The composition has proper viscosity, favorable viscosity-temperature characteristics, favorable low-temperature fluidity, favorable shear stability, favorable viscosity-slip characteristic, favorable lubricating property, favorable cooling property, favorable rust resistance, favorable adaptability to the sealing material, favorable antifoaming property, favorable filterability, favorable demulsibility, favorable clean property, favorable air release characteristic, high thermal oxidation stability, high hydrolytic stability, favorable extreme pressure abrasion resistance, sintering resistance and high transmission stability, and is beneficial to lowering the abrasion and impact load and reducing the vibration and noise.
Description
technical field [0001] The invention belongs to the field of mechanical hydraulic and gear transmission lubricants, in particular to the composition of the working fluid of hydrostatic mechanical power split transmission devices. Background technique [0002] A hydrostatic mechanical power split transmission system is considered to be a transmission system in which hydraulic and mechanical devices are "parallel" and transmit power flow separately. Usually the power flow from the engine into the transmission system is divided into two paths: one is the hydraulic power flow transmitted by the purely hydrostatic drive, and the other is the purely mechanical power flow transmitted by the purely mechanical means, and then the two paths are combined and transmitted to the walking gear. This technology organically combines the good performance of hydrostatic drive stepless speed regulation and the high steady-state efficiency of mechanical rotation, in order to obtain a stepless s...
