Description
Invention field
The utility model relates to dumping car and turns to the fault alarm technology, specially refers to a kind of 8 * 4 dumping cars and turns to failure warning system.
Background technology
8 * 4 dumping cars refer to (four axles) tire that has eight groups, and the heavy self-unloading commercial vehicle/comm..vehicle driven by two groups of tires.Because 8 * 4 dumping cars adopt two front-axle structures, comparatively easily cause and turn to difficulty et out of order.When difficulty et out of order appear turning in steering swivel system, more common reason is steering hydraulic oil pressure deficiency, or steering hydraulic oil flow is inadequate, or steering hydraulic oil liquid level deficiency.Prior art 8 * 4 dumping car steering swivel systems do not arrange and turn to failure warning system, when steering hydraulic oil pressure deficiency appears in steering swivel system, perhaps steering hydraulic oil flow is inadequate, perhaps during the situation such as steering hydraulic oil liquid level deficiency, the operator does not know, be easy to et out of order in the process of moving, even cause the accident.Obviously, prior art 8 * 4 dumping car steering swivel systems exist in the time of difficulty et out of order may occurring turning to does not have alerting signal, so that timely trouble-shooting is avoided the problems such as accident generation.
Summary of the invention
For overcome that prior art 8 * 4 dumping car steering swivel systems exist may occur turning to difficulty et out of order the time there is no alerting signal so that solve in time, avoid the problems such as accident generation, the utility model proposes a kind of 8 * 4 dumping cars and turn to failure alarm circuit.The utility model 8 * 4 dumping cars turn to failure alarm circuit to comprise hydraulic pressure transducer S1 and S2, flow sensor S3, level sensor S4, relay K and controller; Often open sensor S1, S2 and S3 parallel connection, an end ground connection, the other end connects an end of relay K coil; The other end of relay K coil connects vehicle launch K switch 1/15; Normally closed sensor S4 mono-end is by the normally closed contact ground connection of relay K, and the other end connects car body controller BC; Car body controller BC shows that with instrument IC is connected by the CAN of controller local area network; And, be provided with in gauge panel and turn to the failure warning symbol
and corresponding LED lamp; Described often open or normally closed sensor refers to that when detected value during in normal range, the contact of sensor is in opening or closed condition, detected value is when improper scope, and sensor contact is in closing or opening; Wherein,
Sensor S1 and S2 be closure when the driving engine off-duty, is output as active potential, after the driving engine operation, disconnects, and is output as high potential; Sensor S3 is closure when stationary vehicle, is output as active potential, and running velocity disconnects after being greater than 10km/h, is output as high potential; Sensor S4 is closure when the steering hydraulic oil liquid level is normal, is output as active potential, when turning to liquid level low, disconnects, and is output as high potential; When car body controller BC receives high potential, control the LED lamp and open, otherwise, close.
It is when steering swivel system may break down that the utility model 8 * 4 dumping cars turn to the useful technique effect of failure alarm circuit, turns to the failure warning symbol in gauge panel
the bright demonstration, prompting operation person's wheel steering system has fault, so that timely trouble-shooting avoids accident to occur.
The accompanying drawing explanation
Accompanying drawing 1 is that the utility model 8 * 4 dumping cars turn to failure alarm circuit figure.
Below in conjunction with drawings and the specific embodiments, to this practicality 8 * 4 dumping cars, turn to failure alarm circuit to be further described.
The specific embodiment
Accompanying drawing 1 is that the utility model 8 * 4 dumping cars turn to failure alarm circuit figure, and as seen from the figure, the utility model 8 * 4 dumping cars turn to failure alarm circuit to comprise hydraulic pressure transducer S1 and S2, flow sensor S3, level sensor S4, relay K and controller; Often open sensor S1, S2 and S3 parallel connection, an end ground connection, the other end connects an end of relay K coil; The other end of relay K coil connects vehicle launch K switch 1/15; Normally closed sensor S4 mono-end is by the normally closed contact ground connection of relay K, and the other end connects car body controller BC; Car body controller BC shows that with instrument IC is connected by the CAN of controller local area network; And, be provided with in gauge panel and turn to the failure warning symbol
and corresponding LED lamp; Described often open or normally closed sensor refers to that when detected value during in normal range, the contact of sensor is in opening or closed condition, detected value is when improper scope, and sensor contact is in closing or opening; Wherein,
Sensor S1 and S2 be closure when the driving engine off-duty, is output as active potential, after the driving engine operation, disconnects, and is output as high potential; Sensor S3 is closure when stationary vehicle, is output as active potential, and running velocity disconnects after being greater than 10km/h, is output as high potential; Sensor S4 is closure when the steering hydraulic oil liquid level is normal, is output as active potential, when turning to liquid level low, disconnects, and is output as high potential; When car body controller BC receives high potential, control the LED lamp and open, otherwise, close.
Obviously, the utility model 8 * 4 dumping cars turn to hydraulic pressure transducer S1 in failure alarm circuit and S2 for detection of the pressure of hydraulic oil in steering swivel system whether in normal range, whether flow sensor S3 is for detection of the flow of hydraulic oil in steering swivel system in normal range, and whether level sensor S4 is in normal range for detection of steering swivel system hydraulic pressure oil mass.The utility model 8 * 4 dumping cars turn to failure alarm circuit will often open sensor S1, S2 and S3 parallel connection, the high and low current potential that to often open sensor S1, S2 and S3 output by relay K is anti-phase, when often driving sensor S1, S2 and S3 output high potential, what by relay K, output to car body controller BC is active potential, otherwise, be high potential.And relay K is connected to car body controller BC with after steering hydraulic oil liquid level sensor S4 is connected in series.Therefore, when vehicle launch, the driving engine operation, now the speed of a motor vehicle is less than 10km/h, System self-test, sensor S1 and S2 disconnect, sensor S3 closure, be output as active potential, and what by relay K, output to car body controller BC is a high position, car body controller BC controls the LED lamp and opens, and in gauge panel, turns to the failure warning symbol
the bright demonstration; When Vehicle Driving Cycle and the speed of a motor vehicle are greater than 10km/h, sensor S3 disconnects, and is output as high potential, and what by relay K, output to car body controller BC is active potential, and car body controller BC controls the LED lamp and closes.In this process, if any one detected value of sensor S1, S2 and S3 not in normal range, contact all can be closed, be output as active potential, by relay K output to car body controller BC for high-order, car body controller BC controls the LED lamp and opens, and in gauge panel, turns to the failure warning symbol
the bright demonstration, prompting operation person's steering swivel system breaks down.Simultaneously, the detected value of sensor S4 is not when normal range, and contact disconnects, and is output as high potential, and car body controller BC controls the LED lamp and opens, and in gauge panel, turns to the failure warning symbol
the bright demonstration, prompting operation person's steering swivel system breaks down.
Obviously, it is when steering swivel system may break down that the utility model 8 * 4 dumping cars turn to the useful technique effect of failure alarm circuit, turns to the failure warning symbol in gauge panel
the bright demonstration, prompting operation person's wheel steering system has fault, so that timely trouble-shooting avoids accident to occur.
