Abstract

The invention discloses a cleaning equipment brake steering electro-hydraulic control system, which includes a hydraulic oil tank, a hydraulic pump, a flow distribution valve, a steering proportional valve, a steering oil cylinder, a steering gear, a steering reversing valve, a brake reversing valve, and a brake oil circuit. Pressure regulating valve, brake line unloading valve, brake line termination, pressure sensor and control unit. The invention realizes the wire control of the automatic driving (unmanned driving) of the articulated equipment, the steering, braking, and parking; at the same time, the operation control system of the manual driving is retained, and the two systems of the manual driving and the wire control do not conflict with each other. Coupling effect; reduce a set of hydraulic braking system, that is, the combination of hydraulic braking system and hydraulic system reduces the cost of equipment.

Description

technical field [0001] The invention relates to the field of sanitation equipment, in particular to an electro-hydraulic control system for braking and steering of cleaning equipment. Background technique [0002] The articulated cleaning and cleaning vehicle is one of the typical sanitation equipment on the market. The typical technical state is the steering form driven by hydraulic steering gear + hydraulic cylinder, and the traditional hydraulic braking system. In addition, this type of cleaning vehicle also has the characteristics of slow operating (driving) speed. (This feature is related to the feasibility of using hydraulic oil in this patent solution. Because high-speed vehicles have certain requirements for brake oil, hydraulic oil is generally not used for braking.) In addition, the important reason why the existing motor vehicle brake oil cannot use hydraulic oil It is to prevent failure of the hydraulic oil due to high temperature and easy emulsification.
