Embodiment
This practicality is newly described in further detail with specific embodiment below in conjunction with the accompanying drawings, but the utility model is simultaneously
It is not limited to these embodiments.
As shown in figure 1, a kind of disc brake apparatus multistage brake pressure maintaining type hydraulic system, including fuel tank 17, the oil
Case 17 is connected with oil feeding line and skimmer circuit, sequentially concatenated on oil feeding line oil absorption filter 1, gear pump 3, check valve 4 and
Fine filter 5；Skimmer circuit includes the first skimmer circuit and the second skimmer circuit, and the first skimmer circuit is simultaneously connected to proportional pressure control valve
7 and safety valve 8, the second skimmer circuit be simultaneously connected to overflow valve 9 and choke valve 10；Skimmer circuit concatenates two-position four-way solenoid directional control valve
6, and oil feeding line Access Control oil circuit in the lump；Control oil circuit to include four identicals and control branches, it is each control in branch according to
Secondary concatenation two-position two-way electromagnetic directional valve 11 and brake unit 14, control and pressure gauge 13 and pressure sensor are gone back and be connected in branch
12。
Motor 2 is connected with the gear pump 3；The fuel tank 17 is provided with liquid thermometer 15 and air cleaner 16.
Operation principle of the present utility model can be briefly described below.
When opening a sluice gate, two-position four-way solenoid directional control valve 6 must be electric, and the proportional pressure control valve 7 and safety valve 8 of the first skimmer circuit are connected into
Oil circuit, motor 2 drive gear pump 3 to rotate, and are suppressed respectively to four control branches, the electric current for gradually increasing proportional pressure control valve 7 is
The oil pressure of control branch can be increased, so as to reduce braking moment, realization is slowly opened a sluice gate.Open a sluice gate rear two-position two-way electromagnetic directional valve 11
Energization cut-off forms pressurize, and two-position four-way solenoid directional control valve 6 powers off, and proportional pressure control valve 7 is stopped, and reduces fault rate.
During band-type brake, the power-off conducting of two-position two-way electromagnetic directional valve 11, two-position four-way solenoid directional control valve 6 is powered, and reduces ratio
The electric current of overflow valve 7 can reduce the oil pressure of control branch, so as to increase braking moment；Two two of other three control branches
Electric change valve is powered successively, and 1/2,3/4 and the full moment braking of specified braking moment can be achieved.If the electricity of proportional pressure control valve 7
Stream is reduced to a certain numerical value and is kept for a period of time constant, and point brake deceleration can be achieved.
Suddenly during power-off, the two-position two-way electromagnetic directional valve power-off of two-position four-way solenoid directional control valve 6 and four control branches,
Oil pressure gradually reduces through overflow valve 9 and the slow overflow oil return box 17 of choke valve 10, control oil circuit pressure, realizes safety arrestment.
The part do not addressed in the utility model uses or used for reference prior art and can be achieved.
