It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.
Below with reference to accompanying drawing, embodiment of the present utility model is done to concrete explaination.
A kind of redundance type braking in a turn intelligent controlling device and the bulldozer of embodiment of the present utility model as shown in Figure 1.Be applicable to bulldozer, comprise controller 6, the first oil cylinder 11, the first reversal valve 7, the first electromagnetic valve 1 and the first standby electromagnetic valve 5.
The first reversal valve 7 is provided with the first import, the second import and outlet.The first import communicates with the first electromagnetic valve 1, and the second import communicates with the first standby electromagnetic valve 5, and outlet communicates with the first oil cylinder 11.Controller 6 is connected with the first reversal valve 7, the first electromagnetic valve 1 and the first standby electromagnetic valve 5 respectively, and the first import of controller 6 control the first reversal valves 7 or the second import are communicated with or close with outlet.
Embodiment of the present utility model, by adopting redundancy structure, increases standby electromagnetic valve, has improved the reliability of system, has increased the non-failure operation time of equipment.
In embodiment of the present utility model, preferably include the first oil cylinder 11, the second oil cylinder 12, the 3rd oil cylinder 13, the 4th oil cylinder 14 and be respectively left clutch oil cylinder, right clutch oil cylinder, left brake oil cylinder, right brake oil cylinder; The first reversal valve 7, the second reversal valve 8, the 3rd reversal valve 9, the 4th reversal valve 10 are respectively left clutch reversing valve, right clutch reversing valve, left braking reversal valve, right braking reversal valve, and are preferably two-position three-way valve; The first electromagnetic valve 1, the second electromagnetic valve 2, the 3rd electromagnetic valve 3, the 4th electromagnetic valve 4 are respectively left clutch electromagnetic valve, right clutch electromagnetic valve, left braking electromagnetic valve, right braking electromagnetic valve.
Left clutch oil cylinder is connected with left clutch electromagnetic valve by two-position three-way valve, right clutch oil cylinder is connected with right clutch electromagnetic valve by two-position three-way valve, left brake oil cylinder is connected with left braking electromagnetic valve by two-position three-way valve, and right brake oil cylinder is connected with right braking electromagnetic valve 4 by two-position three-way valve 4.
The first standby electromagnetic valve 5 is connected with four two-position three-way valves.The oil-in of the first electromagnetic valve 1, the second electromagnetic valve 2, the 3rd electromagnetic valve 3, the 4th electromagnetic valve the 4, first standby electromagnetic valve 5 is all connected with P mouth, and drain tap is all connected with T mouth, and electromagnetic coil is all connected with controller 6.Between standby electromagnetic valve and braking in a turn oil circuit, be connected with two-bit triplet reversal valve, can when switching to back-up circuit, cut off former fault loop completely, improve reliability.
On left clutch oil cylinder, right clutch oil cylinder, left brake oil cylinder, right brake oil cylinder, be connected to pressure transmitter 15, feedback pressure signal is to controller 6.Two-position three-way valve is all connected with controller 6.Controller 6 reports module 17 for repairment with this earth fault display module 16 and remote failure and is connected.
In addition,, in embodiment of the present utility model, also can be provided with the second standby electromagnetic valve, to improve system reliability.
As shown in Figure 2, in embodiment of the present utility model, as shown in Figure 2, when neutral gear starts, braking in a turn control system starts, and first system initializes, and reversal valve 7,8,9,10(i.e. the first reversal valve 7, the second reversal valve 8, the 3rd reversal valve 9, the 4th reversal valve 10) power-off self check.Controller 6 is to each clutch and the detection electric current of a braking electromagnetic valve scan period of output, and the coil of each electromagnetic valve obtains electric, and pilot pressure changes, corresponding oil cylinder build-up pressure, and pressure transmitter feeds back to controller 6 by the controlled pressure recording.
The controlled pressure that controller 6 feeds back to pressure detecting point and the detection electric current of output contrast, if 4 controlled pressures are all synchronously followed detection curent change, judge whole system normal operation, directly enter armed state; If the controlled pressure of electromagnetic valve detected not with detecting curent change, enter self-repair module.
When system autodiagnosis judgement whole system normal operation, standby electromagnetic valve disconnects with work loop, do not need all standby electromagnetic valve to be carried out to self check at every turn, guarantee that so standby electromagnetic valve is always in original state, can not lose efficacy with together with the electromagnetic valve in other loop.
As shown in Figure 3, after self-repair module starts, first whether failure judgement number of channels is greater than alternate channel quantity.The standby passage of take is example, is only provided with the first standby electromagnetic valve 5, if there is plural solenoid valve failure, directly reports an error; If only have a solenoid valve failure,, in system self reover limit of power, order judges the pressure of four passages, looks for out of order electromagnetic valve place passage, makes corresponding reversal valve energising.Fault electromagnetic valve passage cuts off completely, and the first standby electromagnetic valve 5 is linked into this passage, then the first standby electromagnetic valve 5 is carried out to self check, and the pressure by the standby electromagnetic valve 5 of rear setting first is corresponding clutch or the brake pressure of turning to.
Complete after switching, controller is exported fault and is shown on local display screen, prompting user's self diagnosis result and selfreparing result.User can recognize that fault has occurred the electromagnetic valve of which passage, and whether in repair ability automatically, and whether standby electromagnetic valve is replaced successfully.System sends message from trend server afterwards, reports for repairment fault message is long-range, points out professional maintenance personal to go to further detection to safeguard.Bulldozer still can normally use during this period, reaches the effect of self diagnosis selfreparing, for maintenance personal arrives at scene, has striven for buffer time, has increased the average accident-free duration of bulldozer, meets client's specific demand.
In embodiment of the present utility model, also comprise a kind of bulldozer, be provided with redundance type braking in a turn intelligent controlling device described above.Because above-mentioned redundance type braking in a turn intelligent controlling device has above-mentioned technique effect, therefore, the bulldozer that is provided with this redundance type braking in a turn intelligent controlling device also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
Above specific embodiment of the utility model be have been described in detail, but it is just as example, the utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the utility model is carried out and alternative also all among category of the present utility model.Therefore,, not departing from the equalization conversion of doing under spirit and scope of the present utility model and revising, all should be encompassed in scope of the present utility model.
