Description

A kind of commercial car hydraulic lock monitoring system

Technical field

This utility model relates to automotive safety operation control system, particularly relates to a kind of safety monitoring system in commercial car hydraulic lock.

Background technology

Along with the extensive application of commercial car, people are more and more higher to vehicle performance and the maintenance requirement of commercial car.Medium or severe type commercial car vehicle body needs when being connected with chassis to use the hydraulic lock on portal frame to be fixed by vehicle body.Hydraulic lock belongs to security parts, and the quality of its quality directly influences safety when truck travels, and is also directly connected to the life security of trucker.

Hydraulic lock is used for pinning driver's cabin so that it is keep normal horizontal steering position during travelling.At present, skew easily occurs when most of body overhang supports coordinate with hydraulic lock, increase mutually abrasion, affect the service life of hydraulic lock；Once hydraulic cab goes wrong in being locked in and running at high speed, when truck runs into emergency brake, the emergency such as road surface or head-on crash of jolting, it is likely to occur that driver's cabin surprisingly topples the accident of upset, the life security threatening driver and other members that this accident will be serious.Present stage is not also for the monitoring system of hydraulic lock secure context.

Summary of the invention

For overcoming prior art defect, improve the safety in utilization of hydraulic lock, the utility model proposes a kind of safety monitoring system in commercial car hydraulic lock.

For this; the technical solution of the utility model is: a kind of commercial car hydraulic lock monitoring system; it is grouped into by monitoring part, adjustment member, protection portion; it is characterized in that: described monitoring part includes two positions sensor, single-chip microcomputer, alarm, hydraulic lock detection module; two positions sensor is separately mounted on body overhang and hydraulic lock support; for monitoring the distance between hydraulic lock and body overhang, hydraulic lock detection module is integrated on single-chip microcomputer；Described adjustment member includes return mechanism, return mechanism is arranged on hydraulic lock support, is made up of pull bar system, gear train and driving motor, drives motor to be provided with adjustment button, the outfan driving motor is connected with pull bar system by gear train, and the other end of pull bar system is connected with hydraulic lock support；Described protection portion is divided and is included ECU；Two positions sensor is connected with the input of single-chip microcomputer respectively, and the outfan of single-chip microcomputer is connected with adjustment button and ECU respectively；

When hydraulic lock is normally combined with body overhang, vehicle body is in locking state, and now the distance of two positions Sensor monitoring is zero；When hydraulic lock support occurs crooked or loosening, numerical value on two positions sensor occurs that change sends a signal to single-chip microcomputer, single-chip microcomputer sends a signal to alarm equipment alarm, driver is stopped and is risen by vehicle body, motor is driven to work by adjusting button control, motor is driven to move the existing position of change by pull bar frenulum hydrodynamic pressure lock support, until hydraulic lock just puts back into；When occurring reporting to the police, if Vehicle Speed is too fast, single-chip microcomputer will send a signal to ECU, make speed reduce by limiting engine speed and moment of torsion.

Beneficial effect:

This utility model is by arranging position sensor, single-chip microcomputer, the monitoring system of alarm composition complete set, the behaviour in service of hydraulic lock is monitored, and just carrying out back by arranging return mechanism situation unsceptered to hydraulic lock, improve the safety in utilization of hydraulic lock with this, eliminate potential safety hazard present in vehicle travel process.Use this system effectively to prevent in the case of hydraulic lock goes wrong, automobile run into emergency brake, jolt road surface or head-on crash time, occur that driver's cabin upset of surprisingly toppling causes the generation of misoperation fault, improve travel safety；And system is not restricted by road environment, technology state of vehicle, stable work in work, mounting, commissioning and maintenance is convenient, can be used widely.
