What does a fixed gear ratio transmission mean?
3 Answers
A transmission that changes vehicle speed through different gear ratios of gears is called a fixed gear ratio transmission, which is also a type of electric vehicle transmission. Below are the relevant introductions: 1. Principle: Based on the known transmission body, bearings, and various standard components, a motor flange is installed between the motor and the transmission to integrate the motor and the transmission. The motor output shaft is directly inserted into the connecting sleeve inside the transmission, transmitting power to the first shaft of the transmission through the connecting sleeve. The gear on the first shaft meshes with the driven gear on the differential housing, driving the driven gear to rotate the differential and wheels, completing the power transmission. 2. Advantages: Using this utility model, power is directly transmitted from the motor to the transmission, and the transmission directly transmits power to the two wheels, reducing power loss. It also has advantages such as simple structure, ease of manufacturing, and low production costs.
From my experience driving electric vehicles, a fixed gear ratio transmission is designed with only one fixed speed, unlike traditional gasoline cars that require shifting gears. It's quite common in electric vehicles, and I find it exceptionally smooth in daily driving—direct acceleration without any jerks, no need to press the clutch like in a manual transmission or deal with sudden downshifts in an automatic. The advantages include simple maintenance, fewer parts, and minimal issues, saving both money and hassle. However, the downside is that at high speeds, such as driving at 120km/h, it might be slightly noisier or less efficient compared to multi-speed transmissions. Overall, it makes driving easier, especially suited for urban conditions, and allows new drivers to get the hang of it quickly.
As a car enthusiast, I've observed that a fixed gear ratio transmission is a single-speed design with a constant gear ratio and no shifting process. It's widely used in electric vehicles because electric motors have a broad operating range, efficiently functioning from standstill to high speeds. This design reduces complexity, eliminates the need for a clutch or gear set, and makes the drivetrain lighter and more reliable. I've also noticed that it improves responsiveness, provides smoother acceleration, and reduces the lag associated with traditional transmissions. It's environmentally beneficial as it reduces weight and enhances efficiency. However, its efficiency might slightly decrease during top-speed challenges or steep climbs, requiring adjustments in driving habits.
