Abstract
The utility model relates to a braking control system of a garbage compactor mechanism, which consists of a brake solenoid valve, a controller, an emergency brake button, an engine ECU, an engine hand throttle, a running reversing switch, connecting wires and control software. The controller automatically controls the action of the brake solenoid valve in accordance with the rotating speed of the engine so as to realize the braking or the braking release of the running system. The controller can also automatically control the rotating speed of the engine in accordance with various braking states. Simultaneously, the controller has the emergency braking function through human intervention.
Description
Technical field
The utility model relates to a kind of compactor braking control system that adopts DA walking control that is used in.
Background technology
Compactor in the course of the work, the working condition on ground is complicated and changeable, various cram packers and numerous ragpicker shuttle back and forth wherein frequently simultaneously, and this just requires compactor that safe and reliable brakes will be arranged, to guarantee driver, equipment and ground staff's safety.
Hydraulic travel system generally adopts the hydraulic pressure three-stage brake both at home and abroad at present.The three-stage brake system is meant service braking, service brake and brake hard, and the three adopts respectively according to different situations, and its action principle is quiet liquid braking and brake braking.When compacting machine stopped, rim brake was locked friction plate by spring force, was in on-position.When compacting machine in walking or when work, brake is in opening under the oil pressure effect, its locking is by the brake solenoid control.
Service braking is meant that compacting machine advance, fall back when conversion stop and use, and when reversing switch is got back to meta, it is that quiet liquid braking realizes braking that compacting machine relies on the blocking function of hydraulic system self.For DA control, if engine is when running up, reversing switch is got back to and is got to after meta stops when travelling grade again, and compacting machine can be suddenly from the static high-speed travel state that is transformed into, and this will have very big danger, and this impact is also very big to the infringement of machine.
Service brake is meant compacting machine parking use fast when fair speed is exercised, and operating process is earlier throttle control handle to be got back to idling, presses locking key again, and quiet liquid braking and brake act on simultaneously.This process is because complicated operation, and the reaction time is long and reduced its security.
Brake hard is meant under very urgent situation, directly press emergency stop button, this process is fully by the brake effect, brake not only will overcome the motional inertia of road roller, and to overcome the driving force of hydraulic system, very serious to the damage of the wearing and tearing of brake and machine like this, in case the brake excessive wear causes inefficacy, will cause very big danger to safety.
Summary of the invention
At the deficiency of above-mentioned situation, the utility model provides a kind of Based Intelligent Control, safe in utilization, compactor braking control system that reliability is high of adopting.
This compactor adopts the hydraulic-drive running system of DA control, DA control is the related a kind of control scheme of a kind of flow and engine speed, engine speed improves, and then the hydraulic pump pilot pressure increases, and it is big that its swashplate angle becomes, flow increases, when engine speed surpassed starting speed, compacting machine just started slowly and begins walking, and engine speed is big more, travel speed is fast more, and vice versa.On the hydraulic pump solenoid directional control valve is arranged simultaneously, moving forward and backward of control compacting machine stops when meta.
For achieving the above object, the utility model adopts following design:
A kind of compactor braking control system, by the brake magnetic valve, controller, the snub button, Engine ECU, the engine hand throttle, the reversing switch that travels connects lead and control software is formed.Controller connects hand throttle, the reversing switch that travels, snub button, 24V power supply, Engine ECU, relay, and the brake magnetic valve is connected with the 24V power supply by switch.
Its operation principle is that controller is controlled the action of brake magnetic valve automatically according to engine speed, realizes the braking or the take-off the brake of running gear, perhaps regulates engine speed automatically according to various on-positions, has the emergency braking function of manual intervention simultaneously.
Description of drawings
Fig. 1 is a compactor braking control system schematic diagram.
The specific embodiment
Below in conjunction with the Fig. 1 and the specific embodiment the utility model is described in further detail.
Service braking: reversing switch is got back to meta when travelling, after compacting machine relies on quiet liquid Brake stop, reversing switch is got to the shelves that travel again if travel, controller control engine speed is got back to starting speed, engine speed before memory is stopped simultaneously, in setting-up time, be raised to the setting rotating speed more gently, guaranteed the mild property of compacting machine trip-start like this.
Service brake: in the compactor driving process, throttle control handle is pulled idle position, controller reads engine speed from Engine ECU, if be lower than starting speed, controller is now braked by brake solenoid control brake locks consolidation, if be higher than starting speed, release brake then.This process by system intelligence control, has been simplified operation fully, and is more safe and reliable.
Brake hard: directly press emergency stop button, the effect of controller control this moment brake, controller control engine speed is got back to idling rapidly simultaneously, this moment, the hydraulic pump flow was zero, and driving force also is zero, if this moment not only brake only overcome the motional inertia of road roller, and quiet liquid braking effect simultaneously, like this, not only security performance is higher, and is also minimum to the influence of machine.
