Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The invention relates to an oil-electricity hybrid brake switcher which comprises a main body 1, a piston core 14, a magnet, a sealing cover 13 and a sealing ring 8. The main body 1 is a cuboid, or may be a cylinder, a polygonal cylinder or other irregular shapes. The center of the main body 1 is provided with a left section of cylindrical cavity 5 and a right section of cylindrical cavity 5 with two open ends and a closed middle, and the inner ends of the two sections of cylindrical cavities 5 are provided with a magnet-S10 (or a medium which can be absorbed by magnets such as iron nails) through screws. The piston core 14 comprises three circular piston discs and connecting shafts between the circular piston discs, four axial diversion holes 17 are symmetrically formed in the outer end piston discs on two sides, and a middle piston disc in the middle is a solid disc. A first diversion trench 7 and a second diversion trench 11 are formed between the outer end piston disks and the middle piston disk at two sides and the connecting shaft. The piston core 14 is formed by processing a cylinder, annular first diversion trenches 7 and second diversion trenches 11 are firstly formed on the cylinder at intervals to form three circular piston discs and connecting shafts between the circular piston discs, sealing grooves 16 are formed on the circumferences of the three circular piston discs, four diversion holes 17 are symmetrically processed on the outer end piston discs on two sides, and meanwhile, a semi-diversion hole 15 is formed on the connecting shafts, so that the semi-diversion holes 17 can conveniently flow into the first diversion trenches 7 or the second diversion trenches 11. The circumferences of the outer end piston discs and the middle piston disc at two sides are provided with sealing grooves 16, and sealing rings 8 are arranged in the sealing grooves 16 and used for enhancing the sealing performance and preventing liquid from flowing with other diversion trenches, and friction between the piston core 14 and the cylindrical cavity 5 can be reduced. When the liquid density is high, the piston core seal groove can be considered to be unnecessary to install a seal ring. Under the default state, any side of the diversion trench is in a normally-on state with the oil outlet. The left and right sections of cylindrical cavities 5 are symmetrically provided with piston cores 14, the length of the cylindrical cavities 5 is greater than the axial length of the piston cores 14, the inner side of the cylindrical cavity 5 forms a second pressure cabin 9, and the outer side forms a first pressure cabin 6. The open ends of the two cylindrical cavities 5 are closed by a sealing cover 13 (or an electromagnetic auxiliary device), the outer clamping springs are fixed, and the middle part of the sealing cover 13 is provided with a magnet-N12. The middle parts of the outer sides of the outer end piston discs at the two sides are provided with magnets 18 which are matched with the magnet-S10 and the magnet-N12 respectively, and the corresponding end magnetic poles attract each other. The lower part of the main body 1 is provided with a first oil inlet hole 3 and a second oil inlet hole 4 relative to the cylindrical cavity 5, the first oil inlet hole 3 is communicated with the first pressure cabin 6, the second oil inlet hole 4 is communicated with the second pressure cabin 9, the first oil inlet hole 3 is connected with an artificial brake pump, and the second oil inlet hole 4 is connected with an automatic brake pump. An oil outlet 2 is formed above the main body 1 relative to the second diversion trench 11 (when the piston core 14 is positioned at the top end in the cylindrical cavity 5), and the oil outlet 2 is directly connected with an oil inlet pipeline of the ABS.
The guiding gutter is switched on with one of them inlet port, switch off completely with another inlet port passageway, under automatic braking state, when the manual brake is stepped on, this passageway of central point is switched on with the compression of piston core to the pressure of oil, continue to promote piston core 14 and remove forward under the continuous effect of pressure, the corresponding magnet helping hand absorption of rethread, automatic brake pump passageway is switched off completely, the manual brake passageway switches on completely, liquid oil passes through getting into second guiding gutter 11 from guiding hole 17 through first inlet port 3, circulate through oil outlet 2, the brake is released, defaults manual brake passageway and switches on this moment. Under the default manual brake channel conduction state, when the automatic brake function starts, the pressure of oil compresses the piston core to the central position, the channel is conducted, the piston core is continuously pushed to move forwards under the continuous action of the pressure, the manual brake channel is completely disconnected through corresponding magnet power-assisted adsorption, the automatic brake channel is completely conducted, liquid oil flows from the flow guide hole 17 through the second oil inlet hole 4 into the first flow guide groove 7 through the oil outlet hole 2, braking is relieved, and the default automatic brake channel is conducted at the moment. When the control of the automatic braking system is not released, and the automatic braking system has complete braking or not, the manual foot brake is used for assisting (when the foot brake is stepped on, liquid forms pressure in a piston cavity, when the pressure is larger than the pressure of a magnet, the piston is pushed into the center line of the cavity, an automatic braking channel and a manual braking channel are simultaneously conducted, one of the automatic braking channel and the manual braking channel releases the braking, and the other of the automatic braking channel and the manual braking channel is automatically default to complete channel through the action of hydraulic pressure and the adsorption of the magnet).
The magnet plays a role in assisting positioning, mainly solves the problem that the conduction port between the oil pipes cannot be completely opened to set the auxiliary device, and plays a role in positioning when the oil pipes are cut off. When the magnetic body-S10 and the magnetic body-N12 approach to the piston core 14 and approach to the piston core magnetic body 18, the piston core 14 is absorbed into the top end of the main body cylindrical cavity 5 under the action force of the attraction of the magnetic bodies, the channel of the diversion trench is conducted, the oil pressure channel of the brake pump is conducted, and the magnetic body realizes the positioning auxiliary device set by switching on and off between the holes and the channels.
Either one of the first oil inlet 3 (foot brake passage) and the second oil inlet 4 (automatic brake pump passage) is preferably conducted when hydraulic pressure is input. When the foot brake is braked under the default automatic braking channel, the pressure of foot brake oil is larger than the pressure of a magnetic pole of a magnet, the piston core 14 is compressed and adsorbed to the top end of one end of the second oil inlet hole 4, the automatic braking pump channel is disconnected, the manual braking channel is conducted, liquid oil passes through the second oil inlet hole 4 from the first diversion groove 7 to enter the oil outlet hole 2, when the control of the automatic braking system is not released, the foot brake is released, the oil pressure of the diversion oil pipe 2 is reduced, the pressure of a piston cavity is reduced, the piston core is rebounded to the top end of the oil pipe 2, the first oil inlet hole 3 is conducted, automatic braking is carried out, and the diversion groove channel defaults to the last cut-off channel under the action of no braking.
The piston core 14 is adsorbed by the magnet-S10 end, and when liquid or gas is injected through the first oil inlet 3, the liquid or gas flows out through the flow guide hole 18 of the piston to reach the second flow guide groove 11, and then is output or flows back through the oil outlet 2, and the second oil inlet 4 is blocked.
When the first oil inlet hole 3 is filled with oil, gas and other liquids, the piston is transferred to the magnet-N12 under the action of pressure, the first oil inlet hole 3 flows to the first diversion trench 7 through the diversion hole 18 and the semi-diversion hole 15, flows through the oil pipe, and the piston core 14 is adsorbed by the end of the magnet-N12.
