Abstract
A powershift transmission for a vehicle including an input shaft, a first intermediate shaft, a second intermediate shaft, and an output shaft. The input shaft includes a low driving gearwheel and a high driving gearwheel. The first intermediate shaft includes a low output gearwheel, a high output gearwheel, a first speed driving gearwheel, a second speed driving gearwheel, and a third speed driving gearwheel. The second intermediate shaft includes a first speed output gearwheel, a second speed output gearwheel, a third speed output gearwheel, a first-second group driving gearwheel, and a fourth speed output gearwheel. The output shaft includes a first-second group output gearwheel and a third group gearwheel.

A powershift transmission for a vehicle, comprising:
- an input shaft including a low driving gearwheel and a high driving gearwheel;
- a first intermediate shaft including a low output gearwheel, a high output gearwheel, a first speed driving gearwheel, a second speed driving gearwheel, and a third speed driving gearwheel;
- a second intermediate shaft including a first speed output gearwheel, a second speed output gearwheel, a third speed output gearwheel, a first-second group driving gearwheel, and a fourth speed output gearwheel;
- an output shaft including a first-second group output gearwheel and a third group gearwheel;
- wherein the low driving gearwheel meshes with the low output gearwheel and the high driving gearwheel meshes with the high output gearwheel;
- wherein the first speed gearwheel meshes with the first speed output gearwheel, the second speed driving gearwheel meshes with the second speed output gearwheel, the third speed driving gearwheel meshes with the third speed output gearwheel, and the low output gearwheel meshes with the fourth speed output gearwheel;
- wherein the first-second group driving gearwheel meshes with the first-second output gearwheel and the first speed output gearwheel meshes with the third group gearwheel.
