And they are directly installed on the gear shift handle and the gear selection handle of the gearbox through their piston rods. And they are connected to the gearbox respectively. The clutch cylinder is installed on the gear selection actuator or the gear shift actuator. It is connected to the clutch through the clutch lever. Due to the adoption of the above scheme, the device can be conveniently and compactly installed without changing the overall structure of the car.

Description

An electronic automatic transmission actuator for automobiles

The invention relates to an actuator device of an electronic automatic variable speed control system of an automobile.

At present, the automatic transmission composed of hydraulic torque converter and planetary transmission used in automobiles is limited by its own structure. It is difficult to apply to vans and models that need to shift gears through a lever operating mechanism. In addition, even if the manual gearbox is manipulated by the actuator control cable, the structure is relatively complicated. However, the present invention can effectively convert the control instruction of the electronic system to imitate the trajectory of manual gear shifting into specific actions, and directly push the gear shift handle and the gear selection handle of the manual transmission. Realize the purpose of automatic shifting.

The present invention consists of two parts: a gear selection actuator and a gear shift actuator. The gear shift actuator is directly installed on the gear shift handle and the gear box through the gear shift piston rod. Since the shift actuator has three motion positioning positions I, II, III. Thereby, it is ensured that the shift handle of the gearbox can be rotated by an angle of α every time. The motion is positioned to the position of hanging middle II or advancing gear I, III. The gear selection actuator is also directly installed on the transmission gear selection handle and the gearbox through the gear selection piston rod, and has three or four motion positioning positions A, B, C or A, B, C, D. Therefore, it is ensured that the gear selection handle of the gearbox is rotated by an angle _of α every time, and stops at the corresponding three or four motion positioning positions to complete the gear selection action. At the same time, a clutch oil cylinder is installed on the gear selection actuator to complete the opening and closing action of the clutch. The clutch cylinder can also be mounted on the shift actuator.

Due to the adoption of the above scheme, the device can be conveniently and compactly installed without changing the overall structure of the vehicle, and is convenient for large-scale direct assembly on the gearbox, so that the structure of the actuator is simplified and the volume is smaller.

Description of drawings:

Fig. 1 is the front view of the present invention.

As shown in Figure 1, the present invention is made up of gear selection actuator (1) and shift actuator (2), and clutch oil cylinder (10) is housed on the gear selection actuator, and clutch oil cylinder (10) can also be ) is mounted on the shift actuator (2). The gear shift actuator (2) is directly installed on the gear shift handle (5) and the gear box (4) through the gear shift piston rod (3). Because the shift actuator (2) has 3 motion positioning positions I, II, III. Thereby it is ensured that the gearbox shift lever (5) can rotate an angle of α each time, and the motion is positioned at the middle position II or the gear positions I and III. The gear selection actuator is directly installed on the transmission gear selection handle (6) and the transmission case (4) through the gear selection piston rod (7). The gear selection actuator (1) has three or 4 motion positioning positions A, B, C or A, B, C, D. Thereby guarantee transmission gear selection lever (6) to rotate α ₁ angle at every turn. Accurate motion positioning to the corresponding three or four gear selection positions A, B, C or A, B, C, D. Complete the block selection action. At the same time, a clutch oil cylinder (10) is installed on the gear selection actuator (1), and the clutch lever (8) is pushed through the clutch connecting rod (9) to complete the opening and closing action of the clutch.
