Abstract

The invention discloses an automatic gear transmission for a motor vehicle. A linear stepping motor, spline synchronizers and multiple sensors are used in the automatic gear transmission for the firsttime. The automatic gear transmission can achieve the aim of precise synchronization in the gear shift process. The automatic gear transmission has the advantages that the automatic synchronization process is fast and free of friction; the number of spline teeth of the spline synchronizers is low, operation is simple and reliable, and machining and assembling are easy; and the number of the adopted spline synchronizers is low. If two-stage speed changing is adopted in the transmission, only two spline synchronizers are adopted, and the total number of transmission gears can be dozens. The number of gears of the gear transmission can be increased or decreased by increasing or decreasing the number of pairs of gears. The effect of stepless speed changing can be obtained as long as the number of the gears is large enough.

Description

technical field [0001] The invention relates to a mechanical transmission, in particular to an automatic gear transmission for motor vehicles. Background technique [0002] At present, the gear transmission gears used in motor vehicles have a small number of gears, generally 4-6 gears, which seem stiff when shifting gears, and the transmission ratio is discontinuous. The reason why the number of gears cannot be greatly increased is that the synchronizer design used in the current gear transmission is unscientific, too complicated, and the volume is too large, relying on friction synchronization leads to a high failure rate, and the number of synchronizers used is so large that one must be used for every two gears. Synchronizer. To manufacture a 16-speed gear transmission with current technology, it must be equipped with 8 synchronizers, and the ratio of gears to synchronizers is 2:1. This ratio is unacceptable for any gear transmission. Over the years, people in related f...
