Problems solved by technology

[0002] At present, common transmissions, taking automobiles as an example, are divided into manual and automatic transmissions. Automatic transmissions are divided into stepless, automatic, dual-clutch, parallel shaft and AMT automatic transmissions. When changing gears, the number of actuators is large and each gear The switching process between gears is complicated, there are many control programs, and it is easy to cause shifting interference between gears, complex structure, cumbersome maintenance and high failure rate.

Embodiment 1

[0027] A gear superposition type multi-stage automatic transmission, comprising a power input shaft 15 and a power output shaft 16, the power input shaft 15 is equipped with at least seven driving gears, each driving gear corresponds to a gear position, and the power output shaft corresponds to At least seven driven gears are installed, and each driven gear corresponds to a gear position. In this example, see figure 1 , There are 7 driving gears and 7 driven gears. This power input shaft 15 is provided with first gear driving gear 1, second gear driving gear 2, third gear driving gear 3, fourth gear driving gear 4, fifth gear driving gear 5, sixth gear driving gear 6 and The seventh gear driving gear 7. The power output shaft 16 is provided with the first gear driven gear 8, the second gear driven gear 9, the third gear driven gear 10, the fourth gear driven gear 11, the fifth gear driven gear 12, the sixth gear The driven gear 13 and the seventh-speed driven gear 14 . Clu...

Embodiment 2

[0035] A gear superimposed multi-stage automatic transmission, each driving gear is equipped with a clutch and an overrunning clutch on the outside, the clutch is controlled by the gear shifting oil pressure, the power input shaft drives the working end of the driving gear to rotate through the clutch and the overrunning clutch, the driving gear The working end meshes with the driven gear on the power take-off shaft. Wherein, the first-speed driving gear and the second-speed driving gear are connected in a common clutch; the third-speed driving gear and the fourth-speed driving gear are connected in a co-overrunning clutch; the fifth-speed driving gear, the first-speed driving gear The sixth-speed driving gear is respectively connected with the power input shaft via a clutch-connected shaft, and the seventh-speed driven gear is connected with the power input shaft through an overrunning clutch-connected shaft.

[0036] That is: each driving gear side is provided with an overru...

Abstract

The invention discloses a gear position overlapped type multistage automatic transmission. The gear position overlapped type multistage automatic transmission comprises a power input shaft and a power output shaft. A plurality of driving gears are mounted on the power input shaft. Each driving gear corresponds to one gear position. At least seven driven gears are correspondingly mounted on the power output shaft. Each driven gear corresponds to one gear position. The outer side of each driven gear is provided with a clutch and an overrunning clutch. The clutches are controlled by gear shift oil pressure. The power output shaft drives the working ends of the driven gears to rotate through the clutches and the overrunning clutches. The working ends of the driven gears are meshed with the driving gears on the power input shaft. Compared with the prior art, the gear position overlapped type multistage automatic transmission has the advantages that when the clutches conduct upshifting, the engaged low-gear clutches do not need to be disengaged; when the clutches conduct downshifting, downshifting can be achieved just by disengaging the clutches one by one from the top gear; the gear shifting process is simple and smooth, and the gear shifting speed can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of automatic gear shifting of mechanical torque power transmission such as automobiles, ships, military industry, aviation machine tools, etc., and in particular relates to a gear superimposed multi-stage automatic transmission. Background technique [0002] At present, common transmissions, taking automobiles as an example, are divided into manual and automatic transmissions. Automatic transmissions are divided into stepless, automatic, dual-clutch, parallel shaft and AMT automatic transmissions. When changing gears, the number of actuators is large and each gear The switching process between gears is complicated, there are many control programs, and it is easy to cause shifting interference between gears, complex structure, cumbersome maintenance and high failure rate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a ge...
