Abstract

The invention discloses a hydraulic active anti-rollover system for emergency rescue vehicles. The hydraulic active anti-rollover system comprises a hydraulic system, an anti-rollover actuator and a control system. The hydraulic system comprises a hydraulic motor, an electromagnetic proportional overflow valve, a three-position four-way electromagnetic reversing valve, an energy accumulator, an overflow valve, a hydraulic pump and a filter. The anti-rollover actuator comprises a hydraulic motor, a hydraulic motor reducer, a hydraulic motor reducer mounting plate, a V-shaped oblique arm and a support arm; the support arm is fixedly mounted at the lower portion of a vehicle body; the V-shaped oblique arm is fixedly mounted on the support arm and is fitted to a hydraulic motor reducer outputshaft hole. The control system includes a speed sensor, a wheel angle sensor, a tire pressure monitor, a tilt sensor and a controller. The hydraulic motor herein provides anti-roll torque that acts directly on the vehicle body; no rollover occurs when a vehicle is steered; driving smoothness of the vehicle is unaffected.

Description

technical field [0001] The invention belongs to the technical field of vehicle active safety, and in particular relates to a hydraulic active anti-rollover system of an emergency rescue vehicle. Background technique [0002] Heavy-duty transport vehicles such as emergency rescue vehicles have many on-board equipment, high mobility requirements and complex driving conditions, which make their roll stability poor and prone to rollover hazards. Therefore, how to avoid rollover of emergency rescue vehicles has become one of the research focuses of vehicle active safety technology. Ni Jie proposed and designed a new type of suspension mechanism - anti-roll hydraulic interconnected suspension to reduce the rollover accident of the vehicle , but the hydraulic interconnection suspension of the vehicle must not only ensure the ride comfort of the vehicle, but also play the role of anti-rolling, which requires better coordinated control among multiple hydraulic actuators, and the con...
