Embodiment 1

[0020] Embodiment one, see figure 1 , figure 2 , the selected gearbox 2 has a normal gearbox with 5 forward gears and one reverse gear. , that is, 1st and 2nd gears on the left, 3rd and 4th gears in the middle, 5th gear and reverse gear on the right; Gears are also divided into 3rd, 4th and 5th gears and reverse gears according to the previous position. In this way, the above-mentioned two gears are connected with the connecting rod and the driving rod where the two shifting motors of the device are located.

[0021] Two shift gear motors comprise the first shift gear motor 4 and the second shift gear motor 5, such as figure 1 As shown, the first connecting rod 7 is set in the first dialing motor 4, the output end of the first connecting rod 7 is hinged to the first driving rod 8, and one end of the first driving rod 8 swings with the middle, left and right positions of the gearbox 2 One gear lever connection for shift service. The second shifting motor 5 is provided wit...

Embodiment 2

[0022] In the second embodiment, a two-speed gearbox designed for an electric vehicle gearbox is selected, and the shift lever of the gearbox only needs a gear lever that swings back and forth for shifting service, that is to say, the shift motor of the device only needs the first shift gear The motor 4 cooperates with the first connecting rod 7 and the first shift lever 8 to complete the conversion from the manual gear to the automatic gear.

[0023] There are two schemes for the shifting motors in the above two embodiments, one scheme is as follows: Figure 4 As shown, only the first connecting rod 7 is set in the shifting motor, and the output end of the first connecting rod 7 is hinged to the first shifting rod 8 , and one end of the first shifting rod 8 is connected to a gear lever of the gearbox 2 .

[0024] The second scheme of calling the motor is as Figure 5 As shown, a short connecting rod 13 is set in the shifting motor, and one end of the short connecting rod 13 ...

Abstract

The invention relates to the technical field of automobile gearboxes, in particular to an automatic shift gearbox of an automobile, which solves the problem that the manual gear shift motion of the conventional automobile is complex and easy to cause mal-operation. The gearbox comprises an automatic clutch arranged at one end of the gearbox, the exterior of the gearbox is provided with a program controller which comprises a gearbox output rotating speed detection device, a shift gear of the gearbox is provided with a plurality of shift motors, and the shift motors are connected with a gear rod of the gearbox through a connecting rod mechanism and controlled by the program controller; and when the gear of the automobile is shifted, the power supply of a drive motor is cut off by the program controller so that the automatic clutch is at a disengagement position, and then the program controller informs a shifting motor of shifting to the corresponding gear required by the automobile according to the rotating speed data output by the gear.

Description

technical field [0001] The invention relates to the technical field of automobile gearboxes, in particular to an automobile automatic shift gearbox in which a manual gear is automatically shifted through the operation of the device. Background technique [0002] Existing automobile shifting mainly contains two kinds, and a kind of is manual gear, and a kind of is semi-automatic or full-automatic gear, and their shift mechanism and power source are different. For example, the publication number is CN201034156, a gear selection and shift actuator for an automatic transmission, which is characterized in that the gear selection and shift actuator is composed of a gear selection motor, a gear shift shaft, and a gear shift motor, and the gear selection motor and the gear shift shaft are installed together. The shift shaft is fitted together with the shift motor. For example, the publication number is CN101701626A, an electric vehicle automatic control shifting device, including a...
