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 ...

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 ...

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 ...

What is a granny gear transmission: a question a child might ask but not a childish question. Opinions vary on what constitutes a "granny tranny," but in a nutshell it's a manual transmission with an ...

Optional axle ratios can tailor pickup truck power and efficiency to suit your needs as long as the gearing keeps the engine in its torque sweet spot. Often overlooked, optional gear ratios play a key ...

To make this gear ratio comparison possible, we used a car equipped with a 9-inch Ford housing and had Drivetrain Warehouse set up three centersections with 3.00, 3.50 and 4.11 gearsets. We also used ...

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 ...

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; ...

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 ...
