What Are Hydraulic Clutch and Brake Systems?


Hydraulic clutches and brakes are common equipment pieces that serve numerous uses, regularly being found within industrial, automotive, railway, aerospace, and agricultural applications. The clutch is a device that is capable of transferring power between driving elements, serving both motors and engines alike. Brakes, meanwhile, are intended for the stopping or slowing of moving systems, and the two equipment pieces are regularly used alongside each other for various operations. 


As discussed prior, a hydraulic clutch is a device that can be used to transmit power. Unlike more conventional mechanical clutch types, the hydraulic clutch takes advantage of a fluid coupling that enables rotational power to be transferred between driving members with variable speed, avoiding the issues of shock loading. Within the fluid coupling is a driving turbine or torus, that of which acts as a pump for the creation of flow within fluid coupling chambers. The generated flow is then directed towards the output turbine to drive the assembly, resulting in a transfer of energy due to the connection of the turbine to the driven member of the transmission system.


Hydraulic clutch equipment can come in a variety of types that each serve distinct roles, and the choice between each will typically depend upon the application, performance specifications, and compatibility. Based on the rotational speed, power, torque rating, and maximum pressure of a hydraulic clutch, the performance may be determined. It is also important to consider the maximum torque of a clutch drive, that of which is the value that it can bear before failure. As a last major consideration, one should determine what rotational speed is needed for a given application and compare it to the standard operating speeds of various equipment options.


Hydraulic brakes are paramount for stopping and slowing various moving systems, utilizing fluid pressure upon activation to trigger the braking mechanism. Hydraulic brake equipment may come in a variety of types such as the drum brake, disk brake, band brake, and cone brake. While all take advantage of hydraulics for their functionality, each type has its own braking properties and specifications for speed, power, torque, and maximum pressure.


Before determining which specifications are best for a given application, one must first decide upon the braking style. Drum pads are a type that use a braking pad for stopping power, applying the pad to the rotating surface to reduce speed through friction. With disk brakes, two disks are compressed against the sides of the rotor to slow systems down with friction. Band brakes take advantage of their band material for stopping power, tightening around the rotational surface to slow assemblies. Lastly, the cone brake has a similar functionality as compared to the band brake, albeit using a cone shaped material rather than a band.


In some instances, one may be able to procure combination devices, those of which integrate hydraulic brake and clutch equipment together to serve a common application. When assembled in such a way, the clutch may be disengaged for the means of transferring stopping power to the brakes for their actuation. Whether you are in need of clutch parts, brake systems, pulley components, or a combination assembly, there is no better alternative to ASAP Distribution.
