Automatic transmission quickly enters the domestic bus market

During the Spring Festival this year, the reporters visited relatives and friends in Beijing and chose to take the bus to experience the feeling of taking the bus. On the 18-meter Jinghua Cruiser articulated bus on Chang'an Street, the reporter found that the car couldn't hear the kind of harsh sounds that were often used when the old bus was changed, and it didn't feel like the old models often changed gears. Frustration and comfort have improved significantly over the past.

"This kind of car is equipped with an automatic transmission. It doesn't need to be changed gears all the way. It can be comfortable to drive on." Driver Yang said, "The automatic transmission of the bus is greatly reduced. The number of cars in the past has to be changed by several thousand. Secondly, I feel very tired. Now I am driving an automatic passenger car, which is easier than driving a manual car. Those who have not changed the automatic car can envy us. I heard that the city will add more than 2,000 automatic buses this year. Looking back at the Beijing bus and the burdock.” Speaking of the automatic block bus, Master Yang’s words are full of pride.

City bus waving to automatic transmission

The bus is equipped with an automatic transmission. In the words of Master Yang, "putting it over is something that you can’t even think about." The automatic transmission is a relatively high-grade assembly, similar to large and medium-sized passenger cars, equipped with manual transmissions or automatic transmissions. The price will vary by tens of thousands of yuan. However, in recent years, some large cities in China have increased their investment in public transportation facilities under the guidance of public transport priority policies, and adopted automatic transmissions on buses, so that the configuration of bus buses has been rapidly improved.

It is understood that Shenzhen is one of the first cities in China to use automatic transmissions in batches of buses. At present, more than 30% of the more than 1,000 buses in the city are equipped with automatic transmissions. Beijing's automatic transmission bus is close to 10,000, which is the largest city in the country for automatic transmissions. The bus departments of more than a dozen major cities such as Shanghai, Guangzhou, Hangzhou and Zhengzhou have also selected automatic transmissions for different models.

Experts said that the bus has the characteristics of frequent start, acceleration and braking during the operation. The frequency of the traditional bus clutch is about 10 times that of the general road passenger car. The transmission system related parts are easy to accelerate wear. The automatic transmission makes the entire power system flexible, greatly reducing the transmission shock and improving the reliability and life of the transmission system. In the starting process, the transmission changes according to the external resistance, so that the traction force automatically meets the needs of starting acceleration, etc., and the vehicle is quickly reached the maximum speed, and the average traveling speed is improved. Therefore, bus passenger cars become one of the most ideal carriers for automatic transmissions.

Automatic transmission adds points for safe operation

According to the personnel of the operation department of the Beijing Municipal Public Transport Corporation, in addition to the role of the Olympic environment and public transport priority, the requirements for safe operation have been increasing year by year, which is also an important reason for the bus department to consider the bulk purchase of automatic transmission.

"On the one hand, the higher authorities have higher and higher requirements for safe operation. On the other hand, the compensation for major traffic accidents is also rising. We must do everything we can to ensure operational safety. In the past, a serious traffic accident occurred, usually only by the parties. I bear the responsibility, and the leaders at all levels make a self-criticism. It is different. Now, in the event of a major traffic accident, the leader’s responsibility must be investigated. The leaders of the major traffic accidents may also have to step down. Therefore, leaders at all levels attach importance to safety operations. The degree is much higher than in the past.” An industry insider said that the provision of an automatic transmission to reduce the driver’s labor intensity and focus on the road conditions can be regarded as a measure for the public transport department to improve the quality of safety operations. .

Equipped with an automatic transmission, the driver's operation is greatly simplified. It is easy to drive with only the throttle and brake pedal. It not only improves the smoothness of the vehicle, but also benefits the safe operation.

Domestic automatic transmission still needs to work hard

The pace of automatic transmission entering China's bus market is very fast, but this market is basically monopolized by several well-known foreign brands. Such as the US General Motors' Allison, Germany ZF and Fuyina transmission. Several commercial vehicle transmission manufacturers in China do not currently have the ability to mass produce this product. Although individual companies have samples, their reliability is unstable, and there is still a long way to go before mass production. Most companies are in the research and development stage. The accumulation of experimental data and the improvement and improvement of product performance all take time and cannot enter the market. Therefore, domestic automatic transmission enterprises need to redouble their efforts to catch up with the world's advanced level in the shortest possible time.
