Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0026] Such as figure 1 A mechanical automatic shift control device shown includes a shifter 1, a controller 2 connected to the shifter 1, two shift actuators 4 connected to the controller 2, and a hydraulic pressure connected to the fuel tank. pump3. After the controller 2 compares the speed signals of the input shaft and the output shaft, it automatically calculates the optimal shift time, and sends a shift command to the shift actuator 4 according to the shift request of the shifter 1, and the hydraulic pump 3 is the gear shifter at the same time. The actuator 4 provides hydraulic oil. Such as image 3 As shown: In this embodiment, the input shaft and the output shaft are respectively provided with sensors for measuring their rotational speed, specifically the rotational speed sensor 5 , which is connected to the controller 2 and provides the rotational...

Abstract

The invention relates to a mechanical and automatic gear shifting control device. The mechanical and automatic gear shifting control device comprises a gear shifter, a controller, at least one gear shifting execution mechanism and a hydraulic pump, wherein the controller is connected with the gear shifter and is used for comparing rotating speed signals of an input shaft and an output shaft and sending a gear shifting instruction; the gear shifting execution mechanism is used for executing gear shifting; the hydraulic pump is connected to an oil tank and is used for providing hydraulic oil for the gear shifting execution mechanism; the gear shifting execution mechanism, the hydraulic pump and the controller are connected with one another. A clutch is not needed, the optimum gear shifting time is automatically calculated, the gear shifting speed is high, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a mechanical automatic shift control device. Background technique [0002] At present, domestic and foreign automatic shift gearboxes mainly use clutches to cooperate with shift actuators to switch gear sets. This method has complex structure, high manufacturing cost, and the output speed will fluctuate at the moment of shifting, especially not suitable for constant speed output. use on occasions. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical automatic gear shift control device, which does not need to cooperate with a clutch, has a fast shift speed, and has a small fluctuation range of the output speed during the shift process. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A mechanical automatic shift control device, comprising a shifter, a controller connected to the shifter for comparing input shaft and...
