Embodiment Construction

[0024] in operation, figure 1 The AMT controller 20 shown in FIG. 20 decides when to shift gears and how to shift gears according to the driver's intention, vehicle running state and road surface condition control comprehensive consideration. If the driver steps on the accelerator slightly and needs to accelerate, but the engine speed is already high, the AMT controller calculates based on the best fuel consumption and thinks that it should be up a gear, so it commands to select a higher gear and shift gears. Usually, the gear selection and shifting in the manual transmission are usually selected through a mechanism that can move in the X and Y directions, such as image 3 The 6-speed mechanism shown (5 forward gears and one reverse gear). The 310 that can move in the two directions of X and Y in the middle is a dial. When the shift head is in the middle position of the level, the three shift forks are in the middle state, and none of the gears is engaged, so it is neutral. ...

Abstract

The invention discloses a mechanical automatic gear box with a gear selecting and shifting mechanism with electromagnetic control, which consists of a mechanical automatic gear box and a gear selecting and shifting mechanism with electromagnetic control, wherein the gear selecting and shifting mechanism with electromagnetic control consists of a sliding shifting block assembly with an inner guide rail and a coil (120), a guide rail shaft (130), a shifting block (140) for shifting a shifting fork of the gear box, a spring (150) and a limiting body (160); and the middle sliding shifting block assembly (110) with the inner guide rail and the coil is positioned at a middle position of the guide rail shaft and can overcome spring force to slide on the guide rail shaft. If the device is used for changing the position of the shifting fork in the gear box, a general hydraulic, pneumatic and electric gear shifting device can be substituted. After the mechanical automatic gear box with the gear selecting and shifting mechanism with electromagnetic control is adopted, the gear selecting and shifting mechanism is simplified, the control reaction velocity is increased, and the reliability of the device is improved. The mechanical automatic gear box is suitable for mechanical automatic gear box control of a motor vehicle.

Description

[0001] technical field [0002] The invention relates to a mechanical automatic transmission with an electromagnetically controlled gear selection mechanism, belonging to the technical field of motor vehicle transmission control. Background technique [0003] Due to the advantages of low energy consumption, low emission, low cost and convenient driving, automatic mechanical transmission (AMT) has been accepted and loved by more and more users. AMT replaces the driver to automatically determine the shift time and automatically execute the shift. Common AMT systems have two mechanisms for gear selection and gear shifting. These two mechanisms are usually composed of electric motors, hydraulic or pneumatic devices, etc. to form power actuators. These institutions are relatively complex and expensive. The gearshift mechanism implemented by the electric motor also has the problems of long execution time and motor wear. There are also problems such as air leakage and oil leaka...
