Problems solved by technology

It can be seen from the above that the existing automatic shifting system relies on the computer system to control the shifting process throughout the process, so the existing automatic shifting system is equipped with quite a lot of electronic circuits, which makes its wiring quite complicated, and if the automatic shifting system fails The maintenance cost will also be relatively large

Embodiment Construction

[0017] In order to make the above and / or other purposes, features and advantages of the present invention more comprehensible, preferred embodiments are specifically cited below, together with the accompanying drawings, as follows:

[0018] Please refer to figure 1 , which shows an automatic transmission shift system according to an embodiment of the present invention. This system is configured in a vehicle and at least includes: a transmission control unit (1), a hydraulic master cylinder (2), and a clutch actuator (3), a clutch (4), a sequence valve (5), a shift actuator shift valve (6), a shift actuator (7), and a gearbox (8).

[0019] The speed change control unit (1) can judge whether the vehicle shifts gears; in detail, it can judge whether to shift gears according to the driving parameters of the vehicle. The driving parameters include vehicle speed, accelerator opening, lever position, power source (9) speed or any combination of these. If it is decided to shift gear...

Abstract

The invention provides an automatic gear shifting system for a gearbox. The automatic gear shifting system is configured on a vehicle and comprises a variable speed control unit, a hydraulic master pump, a clutch actuator, a clutch, a sequence valve, a gear shifting actuator conversion valve, a gear shifting actuator and the gearbox. The hydraulic master pump is connected with the variable speed control unit and provided with a first oil way and a second oil way which communicate with each other. The clutch actuator is connected with the first oil way of the hydraulic master pump. The clutch is connected with the clutch actuator. The sequence valve is connected with the second oil way of the hydraulic master pump. The gear shifting actuator conversion valve is connected with the variable speed control unit and the sequence valve. The gear shifting actuator is connected with the gear shifting actuator conversion valve. The gearbox is connected with the gear shifting actuator so that the gearbox can be controlled by the clutch to be engaged with or disengaged from a power source. When gear shifting is conducted on the vehicle, gears of the gearbox are indirectly changed through rising oil body pressure in the second oil way of the hydraulic master pump.

Description

technical field [0001] The present invention relates to the technical field related to vehicles, and in particular relates to an automatic shifting system of a gearbox configured on a vehicle. Background technique [0002] The vehicle shifting process performed by the existing automatic shifting system is as follows: the computer system sends the first command to the clutch to separate the power source and the gearbox before the driving condition of the vehicle reaches the level of gear shifting; the clutch is separated from the power source and the gearbox. After separation, send the second command to the computer system; the computer system then sends the third command to the gearbox to change the gear of the gearbox; then, the gearbox sends the fourth command to the computer system after the gear is changed; the computer system then sends the third command Five commands to the transmission to engage the power source with the transmission. As can be seen from the above, t...
