摘　　要：变速器作为整车传动系统的重要组成部分,其阻力矩也就是拖曳扭矩的大小直接影响到整车的油耗以及驾驶性表现,在低温下这一影响更加严重。文章通过对低温下双离合变速器的拖曳扭矩影响因素进行分析,并对某湿式6档双离合变速器进行测试验证,得出低温下双离合变速器拖曳扭矩的优化改进方向。Resistance torque of transmission, which is also called drag torque, influences a lot on vehicle oil consumption and drivability, and the situation would be even worse under low temperature, as the transmission is always an important component in powertrain. This article is focusing on influence factors of DCT low temperature resistance torque, and points out its optimize methods via tests on a wet-type 6DCT.
