Description
Technical Field
The invention relates to a dumper, in particular to an electro-hydraulic braking method for the dumper.
Background
The existing dumper generally only has mechanical braking, namely hydraulic braking, and when braking is carried out, a driver controls a brake pedal through judgment, so that the braking of the whole dumper is realized. The braking method has the problem that the mechanical loss of the brake is large because a driver subjectively judges that mechanical braking is frequently applied, so that a braking system with low loss and reliable braking needs to be designed. For example, the Chinese patent publication No. 107128293 discloses an electrohydraulic combined braking method for a dump truck, the maximum driving braking force of the vehicle is the superposition of the maximum electric braking force and the supplemented hydraulic braking force; the brake controller BCU calculates the braking force, converts the electric braking force into electric braking torque and transmits the electric braking torque to the vehicle control unit VCU; the hydraulic braking force is converted into a 0-5V voltage signal and then transmitted to a signal converter, the signal converter converts the 0-5V voltage signal into a 4-20mA current signal and transmits the 4-20mA current signal to an electromagnetic proportional valve, and the electromagnetic proportional valve converts the current signal into a pipeline pressure signal for braking; the brake controller is used as a control center of the brake system to collect the operation instruction of the brake pedal and the state information of each part of the whole vehicle in real time, perform control decision according to a corresponding control strategy, and output and adjust the electric brake force and the hydraulic brake pressure in real time. The combined braking system effectively prevents a driver from subjectively judging that mechanical brake is frequently applied to cause large mechanical loss of the brake, but the electricity of the combined braking system is short of a reasonable strategy of electro-hydraulic brake distribution.
