Detailed Description
The invention is further illustrated by the following examples:
as shown in the embodiment of fig. 1 and 2, the electromagnetic air-separating brake booster for the automobile comprises a resistance ring 2 assembled outside a transmission shaft 1 of the automobile, wherein the resistance ring 2 is horizontally and coaxially assembled with the transmission shaft 1, mounting holes uniformly distributed and horizontally surrounding the axis of the resistance ring 2 are machined in the resistance ring 2, a transmission rod 3 capable of rotating from the shaft is assembled in the mounting holes, inner magnetic blocks 31 are uniformly distributed in the transmission rod 3 along the axis, and the connecting line of north and south magnetic poles of the inner magnetic blocks 31 is perpendicular to the axis of the resistance ring 2; the left side and the right side of the resistance ring 2 are respectively provided with an electromagnetic plate 4, one end of the transmission rod 3 extends out of the mounting hole, one end of the resistance ring 2 is in transmission connection with one end of the transmission rod 3 through a speed change block 5, and under the action of the speed change block 5, when the resistance ring 2 rotates for one circle from the shaft, the transmission rod 3 rotates for two circles from the shaft; namely, the rotation speed ratio of the resistance ring 2 to the transmission rod 3 is 1: 2. Meanwhile, in the initial setting, when the inner magnetic block 31 is positioned between the two electromagnetic plates 4, that is, the inner magnetic block 31 is positioned at the upper and lower positions of the transmission shaft 1, the connection line of the north and south magnetic poles of the inner magnetic block 31 is vertical, and when the inner magnetic block 31 is close to one electromagnetic plate 4, that is, the inner magnetic block 31 is positioned at the left and right positions of the transmission shaft 1, the connection line of the north and south magnetic poles of the inner magnetic block 31 is horizontal. Therefore, when the electromagnetic plate 4 is opened, the torque force 4 of the resistance ring 2, which is applied by the inner magnetic block 31 and combined with the magnetic force, to the resistance ring is opposite to the transmission shaft 1. The resistance ring 2 is fixedly connected with the transmission shaft 1. This enables the electromagnetic plate 4 to exert a torsional braking force on the drive shaft 1.
The electromagnetic air-separating brake power assisting device for the automobile is mainly used in a speed reducing structure of the automobile, when the automobile normally runs, the electromagnetic plate 4 is in a power-off state, when the automobile starts to brake and a driver steps on the brake plate, the electromagnetic plate 4 is electrified, and the current introduced into the electromagnetic plate 4 is increased along with the increase of the stepping amplitude of the brake plate; at this time, a magnetic force field is formed in the resistance ring 2, and since the inner magnetic block 31 is assembled on the transmission rod 3, the inner magnetic block 31 generates a magnetic force action under the action of the outer magnetic field, and according to the magnetic force characteristic, when the inner magnetic block 31 is closer to the electromagnetic plate 4, the inner magnetic block is mainly influenced by the magnetic force action of the electromagnetic plate 4. In this embodiment, as shown in fig. 2, the inner magnetic block 31 close to the left electromagnetic plate 4 is mainly influenced by the magnetic force of the left electromagnetic plate 4, and the inner magnetic block 31 close to the right is mainly influenced by the right electromagnetic plate 4; the whole resistance ring 2 is subjected to clockwise torsion, and the transmission shaft 1 rotates anticlockwise at the moment and is subjected to braking resistance. Because the inner magnet 31 rotates along with the transmission rod 3, and the inner magnet 31 applies a torsion opposite to the transmission shaft to the resistance block 2 through the transmission rod 3 in the rotating process of the inner magnet 31, the electromagnetic plate 4 has increasingly large magnetic force along with the brake treading, so that the brake resistance changes along with the treading amplitude of the brake plate, the reverse torsion on the transmission shaft 1 can be increased, the transmission shaft 1 is braked, the braking is realized through the magnetic force action, no friction is generated in the braking process, the abrasion of the automobile in the braking process can be greatly improved, and the service life of the brake structure of the automobile is longer.
In specific design, the electromagnetic plate 4 is connected to a circuit through a direction reverser. At this moment, when the wiring direction of the electromagnetic plate 4 is reversely connected, the electromagnetic plate 4 can generate a torque force in the starting direction on the transmission shaft 1 through the inner magnetic block 31 and the resistance ring 2, so that the torque force when the automobile is started can be quickly improved, and the starting speed of the automobile is higher. The structure is particularly suitable for electric automobiles with new energy sources. It can be used not only for braking, but also for auxiliary starting.
In specific design, the device can be matched with a traditional speed reduction assembly for use, for example, the first half stroke of a brake pad can be connected with an electromagnetic plate 4 of the device through a regulating circuit, and the magnetic force of the electromagnetic plate 4 is changed synchronously with the brake pad. When the brake pedal is stepped on the rear half section, the traditional accelerating device starts to perform hard friction braking on the vehicle, so that larger braking force can be provided to rapidly brake the vehicle.
In the specific design, a revolution gear 21 is fixedly assembled at the rear end of the resistance ring 2, rotation gears 32 are assembled at the ends of the transmission rods 3 extending out of the rear sides of the mounting holes, the speed change block 5 comprises a horizontal speed change shaft 51, a revolution connecting gear 52 and a rotation connecting gear 53 are fixedly connected at the front and rear ends of the speed change shaft 51, a ring gear 54 with transmission teeth processed on the inner side and the outer side is assembled outside the rotation gears 32, the rotation gears 32 are in transmission connection with the rotation connecting gear 53 through the ring gear 54, and the revolution gear 21 is meshed with the revolution connecting gear 52. When the resistance ring 2 rotates along with the transmission shaft, the revolution gear 21 rotates along with the rotation, the revolution gear 21 drives the speed change shaft 51 to rotate through the revolution connecting gear 52, then the rotation connecting gear 53 drives the ring gear 54 to rotate around the speed change shaft 51, the ring gear 54 drives the rotation gear 32 and the transmission rod 3 to rotate through the meshing teeth of the inner ring, so that the transmission rod 3 rotates around the shaft while following the resistance ring 2 to rotate around the shaft, and the transmission rod 3 rotates around the shaft for two times when the resistance ring 2 rotates around the shaft; so that the inner magnet 31 in the transmission rod 3 can always apply clockwise torque to the resistance ring 2 as shown in fig. 2.
In the specific design, more than four mounting holes are processed in the resistance ring 2. In this embodiment, eight mounting holes are designed in the resistance ring, and the transmission rod 3 is assembled in each mounting hole, so that the overall stress of the resistance ring 2 is more balanced, the twisting force of the resistance ring is larger, and the braking or starting effect is better.
More than two inner magnetic blocks 31 are arranged in the transmission rod 3. In the present embodiment, 4 inner magnetic blocks are mounted in each of the transmission bars 3. This further increases the overall twisting force to which the resistance is subjected. In specific design, the inner magnetic block 31 is cylindrical, and the inner magnetic block 31 is fixedly installed in the transmission rod 3.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
