Problems solved by technology

Its disadvantage is non-power shifting, that is, there will be power interruption when shifting gears, which will affect the performance of the vehicle.
At present, there is a solution called dual-clutch automatic transmission (DCT), which solves the phenomenon of power interruption when the existing AMT shifts gears, but there are two sets of clutch units, the control structure is complicated, and the cost is high.

[0029] figure 1 It is a structural schematic diagram of the first embodiment of the present invention. In order to simplify the description of the present invention, the schematic diagram only lists three power branches ( 51 , 52 , 53 ), but this does not limit the present invention. Usually, the transmission has at least three power branches.

[0030] The mechanical automatic transmission comprises a first input shaft (1), a second input shaft (2), two intermediate shafts (31, 32), an output shaft (4) connected with a driven device for outputting power, and Three power branch lines (51, 52, 53) respectively arranged between the two intermediate shafts (31, 32) and the output shaft (4), wherein the power branch lines (51, 53) are arranged between the intermediate shaft (31) and the output shaft Between the shafts (4), the power branch line (52) is arranged between the intermediate shaft (32) and the output shaft (4), and the speed ratios of the power branch lines (51, 52, 53)...

[0066] Figure 11 It is a structural schematic diagram of the second embodiment of the present invention. Different from the first embodiment, the connection device (61) of this example is composed of a one-way clutch (75), a gear pair (81), a coupling tooth (811) and a spline connection unit (91), and the connection device (62) is composed of Gear pair (82) and one-way clutch (73) are made up of, and connection device (63) is made up of one-way clutch (75), gear pair (83), coupling tooth (831) and spline connection unit (93), and connection device (64) is made up of gear pair (84) and one-way clutch (74), and connecting device (61,63) shares a one-way clutch (75). All the other structures and speed ratio relations are the same.

[0067]Wherein the gear pairs (81, 83) share the driving gear, and the gear is connected with the first input shaft (1) through the one-way clutch (75), and the spline connection unit (91) is arranged on the intermediate shaft (31) and is connected ...

[0092] Figure 13 It is a structural schematic diagram of the third embodiment of the present invention. Different from the first embodiment, the connection device (61) of this embodiment is composed of a gear pair (81) and a snap mechanism, and the snap mechanism consists of a snap mechanism active part (812) and a snap mechanism follower (96) Composition, connecting device (63) is made up of gear pair (83) and snap-in mechanism, and snap-in mechanism is made up of snap-in mechanism active part (832) and snap-in mechanism follower (97). The speed ratios of the gear pairs (81, 82, 83, 84) are the same, and the speed ratios of the power branch lines (51, 52, 53) decrease successively. The rest of the structure is the same. Obviously in this case, the first speed ratio of the transmission low gear is greater than the second speed ratio of the adjacent high speed gear and the speed ratio between the first input shaft (1) and any intermediate shaft (31, 32) is equal to the secon...

Abstract

The invention relates to a speed changing device, in particular to an automated mechanical transmission. Existing automated mechanical transmissions (AMT) have the defect that the power failure phenomenon during gear shifting exists. Through dual clutch transmissions (DCT), the power failure phenomenon during gear shifting is eliminated, but two clutch units exist, thus a control structure is complex. The invention aims to provide the automated mechanical transmission which is simple in structure, low in cost and free of power failure during gear shifting. The automated mechanical transmission comprises a first input shaft, a second input shaft, at least two intermediate shafts, at least one output shaft which is connected with a driven device and used for outputting power, and at least three power branch lines arranged between the at least two intermediate shafts and the output shafts correspondingly. The first input shaft is connected with a driver. The second input shaft is connected or disconnected with the driver through a friction clutch. The intermediate shafts are connected or disconnected with the first input shaft and the second input shaft through connecting devices.

Description

technical field [0001] The invention relates to a transmission device, in particular to a mechanical automatic transmission for automobiles. Background technique [0002] Today's mechanical automatic transmission (AMT) is improved on the basis of traditional manual gear transmission; it is an electromechanical-hydraulic integrated automatic transmission that combines the advantages of automatic and manual; AMT has both hydraulic automatic transmission and automatic transmission. It has the advantages of high efficiency, low cost, simple structure and easy manufacture of the original manual transmission gear transmission, and is widely used in the automobile industry. Its disadvantage is non-power shifting, that is, there will be power interruption when shifting gears, which will affect the performance of the vehicle. At present, there is a solution called dual-clutch automatic transmission (DCT), which solves the phenomenon of power interruption when the existing AMT shifts...
