The invention provides an automobile differential type stepless automatic gearbox which is characterized in that a differential mechanism is arranged in a box body, a shell of the differential mechanism is fixedly connected with a driven gear, and a power input shaft on the side of the differential mechanism is fixedly connected with a driving gear meshed with the driven gear; a generator is arranged on the left side outside the box body, a generator rotor shaft is in butt joint with a rotating shaft of a left sun gear of the differential mechanism and provided with a rotating speed sensor, a torque detection device used for detecting forward and reverse rotating torque of the generator rotor shaft is arranged at the joint of the box body and the generator, and the generator is further provided with a generator brake. A rotating shaft of a sun gear on the right side of the differential mechanism is in butt joint with a rotor shaft of the motor and is provided with a rotating speed sensor, and the rotor shaft of the motor serves as a power output shaft. The gearbox is not only suitable for an oil-electric hybrid automobile, but also suitable for a pure fuel automobile, the functions of a clutch are replaced by the combined action of the generator brake and the differential mechanism, a transmission system is simpler, larger torque can be borne, and the working reliability is higher.
本发明提供了一种汽车差速式无级自动变速箱,其箱体内部设有差速器,差速器外壳固定连接从动齿轮,差速器旁侧的动力输入轴固定连接有主动齿轮与从动齿轮相啮合;箱体外部左侧设有发电机,发电机转子轴与差速器左边太阳齿轮的转轴对接并设有转速传感器,箱体与发电机的接合处设有用于检测发电机转子轴正反转扭矩的扭矩检测装置,发电机还装配有发电机制动器;箱体外部右侧设有电动机,差速器右边太阳齿轮的转轴与电动机转子轴对接并设有转速传感器,电动机转子轴作为动力输出轴。本变速箱既适用于油电混动汽车,也适用于纯燃油汽车,其由发电机制动器和差速器共同作用,替代了离合器的功能,传动系统更为简单,能承受更大的扭矩,工作可靠性更高。
