Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0046] The broken shaft detection method of the gearbox described in the embodiment of the present invention is used to detect whether the shaft where the clutch is located in the gearbox is broken. If there are multiple clutches in the gearbox, detect whether the shaft where each clutch is located is broken, so as to determine which clutch or clutches h...

Abstract

The invention relates to the technical field of engineering vehicles, in particular to a method and device for detecting a broken shaft of a gearbox and an engineering vehicle. The broken shaft detection method comprises the steps: obtaining rotating speed values of two ends of a shaft where each clutch in a target gearbox is located and working parameters of each clutch; based on the rotating speed values of the two ends of the shaft where each clutch is located, determining a reference clutch with the possibility of shaft breakage; and comparing the working parameters of the reference clutch with preset conditions, and determining the target clutch with the broken shaft. The reference clutch possibly having broken shaft can be detected through the rotating speed value, shaft breakage detection is carried out in combination with the working parameters of the reference clutch, rotating speed value abnormity caused by the reason of the clutch, such as slipping, can be eliminated, and the accuracy of broken shaft detection is improved.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles, in particular to a broken shaft detection method and device of a gearbox and an engineering vehicle. Background technique [0002] There are two main types of gearboxes on engineering vehicles, planetary gear and fixed shaft. For engineering vehicles, such as non-road cabinet vehicles with high torque such as loaders, the input torque of the gearbox is very large, especially in the harsh working conditions that loaders often switch between D / R directions with vehicle speed. Therefore, for the gearbox, the possibility of broken shaft inside the gearbox increases with the increase of its working life. Therefore, it is necessary to accurately detect whether the shaft of the gearbox is broken during the working process of the gearbox. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a method for detecting a broken shaft of a gearbox ...
