From a load-capacity point of view, the most suitable gearhead ratio has the highest torque density for the most compact (and cost-effective) package. From an application point of view, the best ...

Torque demand is one of the first factors to consider, encompassing nominal torque, acceleration torque, and emergency torque.

Gearing ratios determine how many turns of the driveshaft result in a single turn of the wheels (the car's wheels, not your steering wheel). A higher ratio (e.g. 3:1) makes it easier for the engine to ...

An old joke in physics is that of the “spherical cow”, poking fun at some of the assumptions physicists make when tackling a new problem. Making the problem simple like this can help make its ...

What Is a "Granny Gear?" Opinions vary on what constitutes a "granny transmission," but in a nutshell it's a manual transmission with an extremely low gear ratio that allows the vehicle to crawl along ...

The gearbox connects the power unit to the rear wheels and is responsible for multiplying torque at lower speeds and allowing the engine to ...

One of the biggest differences between electric cars and their conventional counterparts has to do with the drivetrain. An internal combustion vehicle has a multi-speed gearbox with numerous ratios; ...

A transmission is a vehicle’s gearbox. It’s roughly analogous to the gear shifter and chain system employed in bicycles. Transmission components are always mounted straight on the engine so that their ...

Default, conservative gear ratios. Note the smooth curve of the line connecting the ratio graph bars. Gearing ratios determine how many turns of the driveshaft result in a single turn of the wheels ...
