Electro-hydraulic and remote control braking system for off-highway vehicles

Abstract

The invention discloses an electro-hydraulic and remote control braking system for off-highway vehicles. The electro-hydraulic and remote control braking system for off-highway vehicles includes a power unit, an electronic pedal, a valve driver, an electromagnetic proportional brake valve and a moving-standing-integrated multi-disc brake, wherein an output end of the power unit is connected with an input end of the electromagnetic proportional brake valve; an output of the electromagnetic proportional brake valve is connected to an input end of the moving-standing-integrated multi-disc brake ;and an output end of the electronic pedal is connected to an input end of the valve actuator. In the electro-hydraulic and remote control braking system for off-highway vehicles, the pressure of an accumulator is monitored by a pressure sensor integrated in the power unit, and only when the brake requires energy, the pressure sensor sends a starting signal to a motor that drives a hydraulic pump,and when the brake does not require energy, the pressure sensor cuts off the signal of the motor that drives the hydraulic pump, so as to enable the hydraulic pump to stop rotating, and when the brake is used, the hydraulic pump rotates and carries out oil pumping, and when the brake is not used, the hydraulic pump can stop rotating, thus achieving the purpose of energy saving.

Description

technical field [0001] The invention belongs to the technical field of off-road vehicles and industrial slewing equipment, in particular to an electro-hydraulic and remote control braking system for off-road vehicles. Background technique [0002] With the development of the economy, off-highway vehicles and industrial slewing equipment have higher requirements on the operation mode, and the demand for remote control and remote braking in terms of braking is increasing. [0003] Most of the braking methods on off-highway vehicles and industrial slewing equipment adopt air-top oil braking or hydraulic braking. For both, there is a common problem, that is, when the space size of the vehicle is large , due to the transmission of braking energy through air control or hydraulic control, the distance of energy transmission is long due to the long brake pipeline. During the transmission process, there will be a large energy loss, which will also lead to the problem of long energy ...
