  According to their application characteristics, hydraulic coupler can be divided into 3 basic types: ordinary type, a torque limiting type, variable speed type.

  Hydraulic coupler structure of ordinary bauer coupling type is relatively simple, but the effective chamber volume is big, and the transmission efficiency is high. The zero speed torque can be up to 6 ~ 7 times of rated torque, sometimes even 20 times. Because the overload coefficient is big, overload protection performance is poor. It usually is used in drive system that does not need much for overload protection and speed control, and It has a separate torsional vibration and shock mitigation effect.

  A torque-limiting type hydraulic coupler adopted structural measures to limit low transmission ratio torque rise, solve the ordinary hydraulic bauer coupling overload coefficient is too large features, can effectively protect the engine ( and working machine ) do not overload, expanded the application fields of hydraulic coupler.

  Speed adjustable hydraulic coupler, under the condition of the unchanged input speed, changes the output rotational speed and torque, by changing the filled degree of cavity, the so-called displacement regulation. Different from ordinary type and a torque-limiting type hydraulic coupler that can be self cooling, Variable speed hydraulic coupling due to structural reasons and output speed amplitude of accommodation, transfer power must have the outer loop of the working fluid and cooling system, so that the working fluid is constantly in and out of the working chamber, to regulate the working chamber fullness and dissipation of heat.
