Single-H operated power takeoff control system capable of canceling traveling power take-off and use method of single-H operated power takeoff control system

Abstract

The invention relates to a single-H operated power takeoff control system capable of canceling traveling power take-off. The single-H operated power takeoff control system comprises a gas storage cylinder which is communicated with a gas inlet of a power takeoff and a neutral position cylinder after sequentially passing through a power take-off electromagnetic valve and a high-gear shielding valve; a gas outlet of the power takeoff is communicated with a rod port of a power takeoff control cylinder; a gas outlet of the neutral position cylinder is connected with a single-H valve in a rear auxiliary box single-H control system by a gas circuit; and the coil of the power take-off electromagnetic valve is connected in series with a power take-off switch. When the single-H operated power takeoff control system is in use, gas simultaneously enters the power takeoff and the neutral position cylinder to implement synchronization of power take-off and stop and the high-gear shielding valve can prevent the phenomenon of asynchronism of power take-off and stop at the high gear and the phenomenon of extended aeration caused by the fault of the power take-off electromagnetic valve so as to finally avoid sudden hoisting in the traveling process. By the design, not only synchronization of power take-off and stop can be implemented, but also the sudden hoisting phenomenon can be avoided when a vehicle travels and safety is higher.

Description

technical field [0001] The present invention relates to a power take-off control system of a dump truck, in particular to a power take-off control system with a single H operation that cancels driving power take-off and its use method, and is particularly suitable for avoiding sudden The lifting phenomenon enhances the safety of power take-off. Background technique [0002] At present, it often occurs in China that dump trucks are suddenly automatically lifted while driving, so that they hit obstacles. This phenomenon often leads to serious traffic accidents, resulting in huge economic losses, and even car crashes. Although many OEMs and refitting factories have proposed different preventive measures, such as: interlock control of the power take-off device and the parking device, expecting power take-off and parking to be realized at the same time, so as to avoid sudden lifting when driving, but in practical applications , often due to the uncoordinated chain control betwee...
