Description
Technical field
The present invention relates to brake field, and in particular to a kind of dish brake brake hydraulic control system.
Background technology
Dish brake brake is to utilize the disk spring of single-action hydraulic cylinder for brake force, drives the brake disc on Block brake rotating machinery, realizes the mechanical purpose of braking.When mechanical normal operation, disc braking device is in and declutches state, it is necessary to overcome spring force by the hydraulic coupling of single-action hydraulic cylinder, and now hydraulic pump is constantly in working condition, because the run time of machinery is much more than braking time, the significant wastage of hydraulic pressure pump power is caused.
The content of the invention
The technical problem to be solved in the present invention provides a kind of dish brake brake hydraulic control system, existing dish brake brake can be solved to be constantly in working condition in the state hydraulic pump of declutching to overcome the spring force of single-action hydraulic cylinder, the problem of causing to cause the significant wastage of hydraulic pressure pump power.
The present invention is achieved through the following technical solutions：
A kind of dish brake brake hydraulic control system, including driving dish brake brake and brake disc from, the single-action hydraulic cylinder that closes, and the hydraulic pump driven by motor, in the oil inlet insertion fuel tank of the hydraulic pump, the pipeline of the oil-out connection single-action hydraulic cylinder rod end chamber of the hydraulic pump is provided with check valve, the first loop is connected with pipeline between the check valve and single-action hydraulic cylinder, first loop connects fuel tank through the first magnetic valve, electro-hydraulic overflow valve successively.
The further scheme of the present invention is, in addition to the second servo loop in parallel with the first loop, and the second servo loop connects fuel tank through accumulator, the second magnetic valve successively.
The further scheme of the present invention is that the oil return pipe for connecting fuel tank is connected with the pipeline between the hydraulic pump and check valve, and the oil return pipe is provided with overflow valve.
The advantage of the present invention compared with prior art is：
First, electro-hydraulic overflow valve control hydraulic cylinder piston rod cavity pressure is slowly raised until maximum dish brake brake is opened completely, hydraulic pump stops, hydraulic cylinder piston rod cavity pressure is kept in the presence of check valve, the power dissipation of hydraulic pump is greatly reduced, and the temperature of hydraulic oil can be reduced, improve the service life of hydraulic pump；
2nd, accumulator can carry out ftercompction when hydraulic system exists and revealed, and shorten the run time of hydraulic pump, further reduce energy consumption.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
A kind of dish brake brake hydraulic control system as shown in Figure 1, including driving dish brake brake 8 and brake disc 9 from, the single-action hydraulic cylinder 7 of conjunction, and the hydraulic pump 4 driven by motor 3, in the oil inlet insertion fuel tank 1 of the hydraulic pump 4, the pipeline of the oil-out connection rod end chamber of single-action hydraulic cylinder 7 of the hydraulic pump 4 is provided with check valve 6, the first loop and second servo loop are parallel with pipeline between the check valve 6 and single-action hydraulic cylinder 7, first loop is successively through the first magnetic valve 13, electro-hydraulic overflow valve 15 connects fuel tank 1, the second servo loop is successively through accumulator 12, second magnetic valve 14 connects fuel tank 1, the oil return pipe for connecting fuel tank 1 is connected with pipeline between the hydraulic pump 4 and check valve 6, the oil return pipe is provided with overflow valve 5.
When rotating machinery startup is declutched, motor 3 drives hydraulic pump 4 to work, the shut-off of second magnetic valve 14 ends second servo loop, first magnetic valve 13, which is opened, turns on the first loop, hydraulic oil passes through check valve 6, it is partly into the rod end chamber of single-action hydraulic cylinder 7, some enters accumulator 12, remainder flows back to fuel tank 1 through electro-hydraulic overflow valve 15, under the regulation of electro-hydraulic overflow valve 15, the pressure of the rod end chamber of single-action hydraulic cylinder 7 gradually rises until pressure reaches maximum, dish brake brake 8 is driven to be gradually disengaged with brake disc 9 until opening completely, rotating machinery enters normal operating conditions；Then the first magnetic valve 13 is turned off, motor 3 and hydraulic pump 4 stop, into packing state, when hydraulic system causes the pressure of the rod end chamber of single-action hydraulic cylinder 7 gradually to reduce in the presence of leakage, the output hydraulic pressure oil of accumulator 12 realizes ftercompction, to shorten the run time of motor 3 and hydraulic pump 4, when pressure drops to the minimum that rotating machinery is normally run, motor 3 and hydraulic pump 4 are again started up carrying out ftercompction until reaching Pressure maximum value.
When rotating machinery is braked, first magnetic valve 13 is opened, hydraulic oil slowly flows back to fuel tank 1 in the presence of electro-hydraulic overflow valve 15, realize that dish brake brake 8 is slowly contacted with brake disc 9 until rotating machinery is braked completely, first magnetic valve 13 and electro-hydraulic overflow valve 15 are simultaneously turned off, and hydraulic system is stopped.
