Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines (the pipes and hoses containing the brake fluid) are purged of any air bubbles. This is necessary because, while the brake fluid is an incompressible liquid , air bubbles are compressible gas and their presence in the brake system greatly reduces the ...
Bellcranks are often used in aircraft flight control systems to connect the pilot's controls to the control surfaces. For example, on light aircraft, the rudder often has a bellcrank (also called a control horn) whose pivot point is the rudder hinge. A cable connects one of the pilot's rudder pedal to one side of the bellcrank.
Primary flight control is achieved by use of dual control wheels and rudder pedals. The control wheels operate the elevator and ailerons mechanically through a system of cables, pulleys, push-pull tubes and bell cranks. Trim functions, microphone keying, autopilot override and steering system switches are located on the control wheels.
A Block and bleed manifold is a hydraulic manifold that combines one or more block/isolate valves, usually ball valves, and one or more bleed/vent valves, usually ball or needle valves, into one component for interface with other components (pressure measurement transmitters, gauges, switches, etc.) of a hydraulic system. The purpose of the ...

The system is fully regenerative: all of the engine's power reaches the track either through the main driveshaft or the steering system; none of the energy is being lost to brakes or clutches. Additionally, since power is fed around the transmission to the steering system, in some designs the tank can be turned or even pivoted in place even ...
The steering linkage which connects the steering gearbox to the front wheels consists of a number of rods. These rods are connected with a socket arrangement similar to a ball joint, called a tie rod end, allowing the linkage to move back and forth freely so that the steering effort will not interfere with the vehicles up-and-down motion as the ...
At lower speeds, the DSR system will increase the steering ratio by having the electric motor provide more assistance to the hydraulic steering system. [2] Thus, less torque is needed to be applied to the steering wheel when making sharp turns. This makes the action of steering feel lighter and more controlled. [5]
