Embodiment Construction

[0017] The refueling truck interlock speed limit control system of the present embodiment is as follows: figure 1 As shown, it includes two-position three-way parking interlock solenoid valve 1 and preselection valve 4, where IN is the intake port. The outlet end of the parking interlock solenoid valve 1 leads to the controlled end of the two-position three-way interlock control air control valve 5, and is also connected to the double-chamber brake air chamber 7 through the third shuttle valve C and the hand brake valve 2. The outlet port of the pre-selection valve 4 leads to the variable-speed controlled end of the gearbox through the first shuttle valve A—the air control port of the reversing air valve, and at the same time leads to the two-position three-way interlock control air control valve 5 through the two-position three-way interlocking control port. Through the controlled end of the bodywork neutral control air control valve 6, the outlet end of the bodywork neutral ...

Abstract

The invention relates to an interlocking speed limit control system of a refueling truck, which belongs to the technical field of a special purpose vehicle. An outlet end of a parking interlocking magnetic valve of the system is led to a controlled end of an interlocking control pneumatic control valve, and is connected with a double-cavity brake chamber at the same time; an outlet end of a preselector valve is led to a variable-speed controlled end of a gearbox, and is also led to a controlled end of a top assembling neutral position control pneumatic control valve, and an outlet end of the top assembling neutral position control pneumatic control valve is led to a neutral position controlled end of the gearbox. In addition, the interlocking speed limit control system of the refueling truck also comprises a parking interlocking override switch valve provided with a first outlet end and a second outlet end, an inlet end of the parking interlocking override switch valve is connected with the outlet end of the preselector valve in parallel, the first outlet end is led to a hand brake valve, and the second outlet end is led to the variable-speed controlled end of the gearbox, and simultaneously is led to an inlet end of the top assembling neutral position control pneumatic control valve. According to the invention, the abnormal movement of a vehicle caused by nonstandard operation is effectively avoided, a quick reaction capability under a condition of emergency evacuation is provided for the system, the speed limit control when the vehicle is driven in a field is provided at the same time, and the control function is more comprehensive.

Description

technical field [0001] The invention relates to a control system of a special-purpose vehicle, in particular to an interlocking speed-limiting control system of a refueling vehicle, which belongs to the technical field of special-purpose vehicles. Background technique [0002] Aircraft refueling truck is a special vehicle widely used in the aviation fuel supply industry at present. It is composed of a special vehicle chassis and a special device for aviation fuel supply (that is, the bodywork). The bodywork mainly includes the oil pump system, oil tank assembly, control room, and hydraulic system , logic control system, lifting platform, etc. Its working principle is: the power is provided by the power take-off of the second-class automobile chassis, and the power is transmitted to the centrifugal pump and hydraulic pump through the power take-off transmission distribution system, and the transmission of aviation fuel is completed through the pump oil system. During the sup...
