Will the transmission industry decline due to new energy vehicles? There is still a lot of room for improvement

The transmission is a very critical component of traditional fuel vehicles and one of the three major parts of traditional cars. The main function of the transmission in traditional fuel vehicles is to coordinate the engine speed and the actual driving speed of the wheels, so that the engine can perform at its best.

But for new energy vehicles, the role of the transmission is not that important. The motor has a high speed and a wide speed range, and has high torque at low speeds, so the process from standstill to top speed only requires a simple increase in speed, without changing the transmission ratio or shifting gears.

Because of the advantages of electric motors over fuel engines, the transmission has a very limited effect on improving the driving performance of electric vehicles. In addition, the transmission will increase the weight of the car, thereby reducing the valuable endurance of electric vehicles.

Pure electric vehicles are not suitable for installing traditional transmissions. Because traditional transmissions are large in size, they will take up space in the battery pack. Traditional transmissions will also reduce the transmission efficiency of electric vehicles and drag down the endurance of electric vehicles. Transmissions are expensive and will increase the cost of electric vehicles.

At present, most electric vehicles in China do not have a transmission in the traditional sense. Most pure electric vehicles are only equipped with a single-speed transmission. This type of transmission is low in cost, easy to install, has a low failure rate, is small in size, and has low power loss. However, this type of transmission will restrict the speed of the electric vehicle, causing the performance of the electric vehicle to decrease when driving at high speeds.

However, for hybrid vehicles, the transmission is still a core component, but it needs to undergo certain modifications.

Some industry insiders said that the two-speed transmission can improve motor efficiency and allow electric vehicles to perform better at high speeds. However, due to technical factors, it has not yet been popularized. Others support that the five-speed transmission, which is improved from the traditional transmission, will become the mainstream.

The popularization of electric vehicles will take time. As a transition between electric vehicles and fuel vehicles, hybrid vehicles will account for a large proportion in the future. In the short term, there is still a broad application space for transmissions. The automotive industry will also prepare for each technical route.
