Abstract
The invention relates to a novel automatic transmission of a planetary gear mechanism, which is a speed change mechanism for changing the output rotating speed of a motor of a new energy automobile, wherein a sliding sleeve is moved by a speed change motor and a screw mechanism (or a ball screw mechanism) so that an inner gear ring is combined with a shell (at the moment, a first gear is arranged), or is separated from the shell (at the moment, a neutral gear is arranged), or the inner gear ring is combined with a planet wheel (at the moment, a planet row is locked, namely a direct gear is arranged), lubricating oil is not arranged in the shell, lubricating grease of lubricating grease is only needed to be coated on a bearing and a gear, and the novel automatic.
Description
Technical Field
The invention relates to a longitudinally-arranged automatic transmission device on a new energy automobile, in particular to an automatic transmission with outstanding advantages in the aspects of the structure and the efficiency of the automatic transmission.
Background
The existing longitudinal drive of the new energy automobile is directly driven or drives a rear axle by using a form improved by a traditional transmission, and the transmission is not used or is modified by using a parallel shaft type transmission. There are many domestic manufacturers of parallel shaft transmissions, such as: west ampere, fujin, zhong de, tang shan einxin, etc. The invention is the first domestic transmission with a planetary row type structure, and has the advantages of simple structure, long service life, large transmission torque, small unit volume and weight. The invention relates to a gear box without engine oil, which is an important invention of the device.
Disclosure of Invention
The invention relates to the technical field of a two-gear automatic transmission (2 AT for short): the invention is suitable for automatic speed changing devices of various fixed or walking transmission machines; is particularly suitable for new energy automobiles. (2: two gears, A: automatically controlled by a motor, T: speed change gear with gears)
The planetary gear set consists of a shell, an input shaft, a set of planetary gear set, an output sensor signal panel and a sensor, an output shaft and a flange, a screw rod, a variable speed shifting fork, a shifting sliding sleeve (with a synchronizer), a variable speed motor and the like. In the invention, one set of speed change gear mechanism is a planetary gear mechanism which adopts a sun gear, a planet gear and a planet carrier, the speed change is realized by meshing different gears by using a sliding sleeve, a spline of a gear ring and a spline of a shell are combined into a first gear, and the spline of the gear ring and the spline of an input shaft are combined into a direct gear (namely 2 gears). When the mechanism is directly blocked, the gear mechanism is in a locking state. No lubricating oil is required. The gear grease with low speed in the first gear can complete the work.
