Abstract

The invention discloses a vehicle steering stabilization system, a method and a mining dump truck, which belong to the field of mechanical control. The vehicle steering stabilization system includes at least four wheels arranged at the bottom, an oil-pneumatic suspension cylinder connected to the wheels, and a power mechanism. Including a pressure sensor (1), a controller (2) and an actuator (3), the pressure sensor (1) is set on the oil-air suspension cylinder, and the controller (2) is respectively connected with the pressure sensor (1) and the actuator (3) . The actuator (3) is connected to the power mechanism of the vehicle, and the controller (2) judges the unbalanced load state and steering state of the vehicle through the signal transmitted by the pressure sensor (1), and controls the power mechanism of the vehicle through the actuator (3). The technical scheme of the present invention uses the pressure sensor installed on the vehicle to judge the approximate position of the vehicle's center of gravity offset according to the pressure value, and judges the current steering direction of the vehicle according to the change characteristics of the pressure value when turning, so as to effectively control heavy loads and low speed mines. The stability of the steering of the car improves the driving safety.

Description

[0001] The invention belongs to the field of mechanical equipment control, and relates to a steering stabilization system, in particular to a vehicle steering stabilization system, a method and a mining dump truck. Background technique [0002] Mining dump truck refers to a non-highway heavy dump truck used in open-pit mines to complete the tasks of rock and earth stripping and ore transportation. It is suitable for various mines and water conservancy projects; it has the characteristics of short travel distance, small turning radius, heavy load, and large geometric size. With the development of more and more large-scale open-pit mining areas and the construction of large-scale projects, mining dump trucks have been more used and developed. The electro-hydraulic integrated control of mining dump truck has become one of the key technologies. [0003] Mining dump trucks are mainly used for loading and unloading in mines. The general environment of mines where mining dump truck...
