X-by-wire system improved the response time by eliminating the mechanical linkage
. The growing demand of highly precise and accurate motion control vehicles in automobile industry further leads to drive the demand of X-by-wire system across the world.
Two popular shift system used are rod shift mechanical linkage
system and cable shift system, these systems have their inherent advantages and disadvantages and are adapted as per the demand of the vehicle layout.
Factors linked to gearbox include synchronizers, inertia of gears, dog teeth geometry, step ratio, oil drag, GSL leverage, aspect ratio, dampening bushes, detent spring stiffness, mechanical linkage
resistance and stiffness, profile for guiding rails detent etc., whereas external factors are clutch inertia, driveline stiffness, shifting rpm, driving condition etc.
A sensor, a remote actuator and multiple control systems have replaced the mechanical linkage
. As the number of power electronics subsystems in the vehicle grows, the automobile itself begins to look like an electrical microgrid with a common power bus connecting a growing list of sources and sinks of power, each managed by an independent embedded control system.
A potential problem with an electro-mechanical cam is that over a period of time the mechanical linkage
system may experience 'slippage'due to wear- resulting in a lack of precision that reduces burner efficiency and performance.
Sarrus's mechanical linkage
converts a limited circular motion to a linear motion, without reference guideways.
The wiping contacts, mechanical linkage
with two-step actuation, clean contacts providing high, positive contact pressure and longer contact life.
Its small package and lack of mechanical linkage
to the transmission opens space below and above.
Novotechnik's (Southborough, MA) Vert-X 31E Series of programmable rotary angle sensors are touchless sensors with a permanent magnet that can be secured to a rotating shaft, so that there is no direct mechanical linkage
between the shaft and the measuring system.
Marcum elaborates: "For desalination, the mechanical linkage
brings in the sea water, compresses it, sends it through filters and takes the water to the shore.
Over the past several years, the team has iteratively improved the mechanical linkage
, the operator interface, and the control method to improve the system's performance.
