What is the optimal gear ratio for manual transmission parking?

[VanElliott]

Optimal gear ratio: When a pair of standard gears mesh, their transmission ratio is: I12=N1/N2=Z2/Z1. The transmission ratio of a fixed-axis gear train: The ratio of the rotational speed (or angular velocity) of the first and last gears in the gear train. I=N_first/N_last There are roughly two or three types of transmission ratios. Below is an introduction to gear ratios: 1. The meaning of gear ratio: When two gears of different diameters are combined and rotate, the larger diameter gear naturally rotates slower than the smaller diameter gear. The speed ratio is actually inversely proportional to the gear diameter. The engine speed in a car is changed by the gear set in the transmission before being delivered to the wheels. The transmission contains several sets of gears with different gear ratios for the driver to choose from, matching the speed and load. Shifting gears while driving means selecting different combinations of gear ratios. 2. The correct gear ratio: Based on the motor's T-number, the track's grip, the size of the venue, and the characteristics of the curves, continuous testing is required to select. It should provide quick acceleration and also maintain speed on straight paths.
