External gear pump for automatic transmission
External gear pump for automatic transmission
Involute gear and cycloid rotor are used to replace new type line, usually with a crescent and non crescent two, line by line arc + two alternative, which not only improves the capacity and efficiency of the pump, but also reduces the hydraulic pressure pulse and noise, low pump power consumption; in addition variable displacement pump is used in the transmission oil pump, further reduces the pump power consumption.

Lightweight materials
Lightweight materials
Now to reduce component weight has become a more important design requirements, and nylon plastic parts has been used in oil pump, such as pressure limiting valve plunger pump, gear pump, internal rotor, especially the pump gear and the rotor adopts nylon plastic, not only reduces the weight of the part, and reduces the pump power consumption, reduce noise.
