Abstract

A vehicular seven-speed transmission is used for improving the power performance, the economical efficiency and the emission performance of a vehicle, and meets the pursuit of people on driving pleasure. The vehicular seven-speed transmission is provided with an input shaft, a first intermediate shaft, a second intermediate shaft, a third intermediate shaft, a first intermediate shaft pinion, a second intermediate shaft pinion, a third intermediate shaft pinion, a differential large gear, an all-gear transmission gear group and a synchronous mechanism. The front end of the input shaft is tightly connected with a clutch, the first intermediate shaft, the second intermediate shaft and the third intermediate shaft are parallel to the input shaft, the first intermediate shaft pinion, the second intermediate shaft pinion and the third intermediate shaft pinion are matched with the differential large gear, and the all-gear transmission gear group and the synchronous mechanism are mounted on corresponding transmission shafts. The vehicular seven-speed transmission provides speed ratio at smaller intervals for the vehicle, so that output power of an engine is smoothly linked, and gear shifting is more comfortable. The high-gear transmission speed ratio of the vehicular seven-speed transmission can be lower, so that the economical efficiency and the emission performance of an automobile in high-speed running are improved.

Description

technical field [0001] The invention relates to a vehicle transmission, especially suitable for a manual seven-speed transmission of an automobile, and belongs to the technical field of automobiles. Background technique [0002] At present, the number of gears of manual transmission (MT) and mechanical automatic transmission (AMT) configured on cars is mostly five-speed and six-speed, while some automatic transmissions, such as AT and DCT, have begun to develop to more gears, equipped with Automobiles with multi-gear transmissions have obvious advantages in power performance, fuel economy and emission performance when running in complex working conditions. With the increasingly stringent emission regulations and people's pursuit of multi-road conditions and multi-gear driving pleasure, traditional five-speed, six-speed manual transmissions and automatic transmissions with fewer gears can no longer meet people's needs. [0003] The manual seven-speed transmission for vehicle...
