Recently, the Beijing Science and Technology Olympics electric vehicle major special group held the 4A110 automatic mechanical transmission product appraisal meeting at the Beijing Gear General Factory. After careful discussion and inquiry by the expert group, the product successfully passed the appraisal.

The 4A110 Olympic electric vehicle transmission consists of the 4S110 transmission developed by Beijing Gear Factory and the AMT control system of Beijing Institute of Technology. It belongs to the “Science and Technology Olympics” project of the Beijing Municipal Science and Technology Commission and is highly valued by the Beijing Municipal Government. Under the coordination of the Municipal Science and Technology Commission, North Tooth participated in the project and undertook the task of developing a three-speed transmission. Seven sets of electric vehicle transmissions were provided for the loading of pure electric buses before the end of October 2006.

After receiving the task on August 7, 2006, the North Tooth Transfer will be immediately put into the work, and the designer will come up with the design plan as quickly as possible. At the same time of careful organization and production, Beifang has repeatedly conducted technical research and improvement with Beijing Institute of Technology. Product noise, synchronizer life, static torsion, assembly fatigue life, dynamic shifting force bench and other tests have reached the national standard evaluation. Claim. On October 31, the North Gear delivered the transmission assembly to the passenger car factory on time.

At present, the road test of the test sites of the two electric vehicles is nearing completion, and the transmission assembly provided by the Beijing Gear Factory is working well.
