Embodiment 1

[0065] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is:

[0066] An unmanned automatic shifting device for crawler driving equipment, such as figure 1 As shown, it includes a control module 1 , an angle sensor 4 , an automatic clutch actuator 3 and at least two automatic shift devices 2 . Wherein, each automatic shifting device 2 is used for correspondingly controlling different gears of the crawler-tracked traveling equipment except the neutral gear. All automatic shifting devices 2 are provided with a neutral gear and are used to control the crawler traveling equipment to be in a neutral gear when all automatic shifting devices 2 are in neutral gear. Each automatic shifting device 2 includes a shifting motor 6 and a shifting swing arm 5 . The control module 1 is connected with the shift motor 6 and the angle sensor 4 respectively, the movable end of the shift motor 6 is connected with the shift arm 5 and is used to drive the shift arm 5 ...

Embodiment 2

[0069] Please refer to image 3 , the second embodiment of the present invention is:

[0070] An unmanned automatic shifting method for crawler driving equipment, on the basis of the first embodiment above, such as image 3 shown, including the following steps:

[0071] S0, judging whether the self-learning instruction is received, if so, recording the measurement values ​​of the corresponding angle sensors 4 when the shift arm 5 on each automatic shifting device 2 is in different gear positions, as a preset shift value group; Record the measurement values ​​of the corresponding angle sensor 4 when the clutch motor 7 is at the clutch separation position, the clutch separation critical position and the clutch connection position, respectively record as the clutch separation value, the clutch separation critical value and the clutch connection value; otherwise judge again. In this embodiment, the device needs to carry out a self-learning process when it is enabled, manually pe...

Abstract

The invention discloses an unmanned automatic gear shifting device and method for crawler belt driving equipment. The unmanned automatic gear shifting device comprises a control module and at least two automatic gear shifting devices. Wherein the control module is connected with each automatic gear shifting device, and each automatic gear shifting device is used for correspondingly controlling different gears, except the neutral gear, of the crawler belt driving equipment. And all the automatic gear shifting devices are provided with neutral gears and are used for controlling the crawler running equipment to be in a neutral gear state when all the automatic gear shifting devices are in the neutral gear state. During use, a gear shifting instruction is received firstly; then, all the automatic gear shifting devices are adjusted to neutral gears, so that the crawler belt driving equipment is changed into the neutral gear; and finally, the corresponding gear of the automatic gear shifting device is adjusted according to the gear shifting instruction, and gear shifting is completed. The multiple automatic gear shifting devices are responsible for controlling different gears respectively, the neutral gear is engaged firstly and then the gear is switched during each time of gear shifting, manual operation is not needed, and the efficiency and the accuracy of gear shifting operation execution of crawler belt driving equipment are effectively improved.

Description

technical field [0001] The invention relates to the technical field of unmanned driving, in particular to an unmanned automatic shifting device and method for crawler-tracked driving equipment. Background technique [0002] The existing crawler driving equipment is a 5-speed shifting mechanism, which adopts the same gear structure as conventional vehicles, and the sequence of shifting gears is a linear combination. The corresponding shifting mechanism is a combination of a gear selection mechanism and a gear shifting mechanism. Complete the 6-speed shift (R gear, 1, 2, 3, 4, 5 gear, neutral gear). However, the gear shifting mechanism of this type of crawler driving equipment has large motion torque, large shift stroke gap, and uncompact clutch structure, which leads to long time-consuming, difficult and error-prone gear shifting operations of crawler driving equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to pro...
