Abstract

The invention relates to the field of heavy vehicle steering systems, in particular to a double-head fire truck steering system which can optimize the power assisting effect of the steering system. The steering system comprises an electric control hydraulic steering system and a mechanical steering system, the mechanical steering system is an active steering system and is directly controlled by adriver, and the electric control hydraulic steering system can be adopted as passive assistance to assist the mechanical steering system in completing various steering operations according to workingconditions.

Description

technical field [0001] The invention relates to the field of heavy-duty vehicle steering systems, in particular to a double-head fire truck steering system. Background technique [0002] At present, mainstream trucks and conventional fire trucks generally use a cab with a steering system. Due to the particularity of the environment in which the fire truck is used, it is often necessary to enter and exit narrow, dead-end alleys. The equipment on the fire truck is bulky and the reverse view is poor. There is an urgent need for a car that can be driven at both ends of the vehicle without turning around or reversing in a special environment. . Improve the speed of fire trucks dispatching police to save the lives and property of the people. [0003] However, the double-headed heavy-duty vehicles have a larger body shape and higher requirements for steering assistance, and ordinary steering systems are less effective under high-load conditions. Contents of the invention [00...
