Abstract

The invention relates to a double-H operated power takeoff pneumatic control system capable of carrying out traveling power take-off. The electrical control system comprises a gas storage cylinder which is communicated with a gas inlet of a power takeoff after sequentially passing through a power take-off electromagnetic valve and a high-gear shielding valve and meanwhile is communicated with a double-H valve in a rear auxiliary box double-H control system after sequentially passing through a stop electromagnetic valve and a neutral position cylinder; a gas outlet of the stop electromagnetic valve is communicated with a control port of a low-gear control valve; the coil of the stop electromagnetic valve is connected in series with a stop switch; in the traveling power take-off process, the low-gear control switch ensures that a vehicle can take off power only at the low gear; and in the stop power take-off process, the vehicle is stopped by the stop electromagnetic valve and the low-gear control switch is closed to conduct the power take-off electromagnetic valve so as to carry out stop power take-off. By the design, not only the sudden hoisting phenomenon can be avoided, but also traveling power take-off and stop power take-off can be safely carried out.

Description

technical field [0001] The invention relates to a power take-off control system of a dump truck, in particular to an air control system of a power take-off controlled by a double H that can be driven by a vehicle and a method of use thereof. The driving force is taken off, and the power is taken off when parking. 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 put forward different preventive measures, none of them can solve such problems fundamentally. [0003] The Chinese patent authorization announcement number is CN2837570Y, and the utility model patent whose authorization announcement date is November 15, 2006 discloses an air control device for a hydraulic dumping mechanism of a dump vehicle. The ...
