What does a single-speed gearbox for electric vehicles mean?

Now many car owners have bought pure trams, because pure trams burn electricity instead of oil, and the electricity price is cheaper than fuel, which is also conducive to energy conservation and emission reduction. So what does the single-speed gearbox of electric vehicles mean?

The single-speed gearbox of electric vehicle, also known as single-stage transmission ratio gearbox and fixed transmission ratio gearbox, is a gearbox that changes the speed through different speed ratios of gears. At present, most electric vehicles on the market use single-speed gearboxes.

At present, most electric vehicles use single-speed gearbox, which is determined by its own characteristics. Unlike the fuel engine, the motor of an electric vehicle can directly transmit power to the wheels, so it only needs a single-speed gearbox.

In addition, the single-speed gearbox has simple structure, easy installation, relatively low failure rate and cost, and relatively small volume; Therefore, the speed regulation function is relatively simple, and it is impossible to speed up after the vehicle reaches the limit.
