Several first electromagnet of rear side power on, these first electromagnet mutually attract with the second electromagnet；The friction block stops
Mechanism of car has friction block 4, and so that it is stopped operating by the way that friction block is pressed to wheel disc.
When brake, magnetic speed mechanism first works, and the second electromagnet is powered, if connecing electrical component on rear side of the second electromagnet
Dry first electromagnet powers on, these first electromagnet and the second electromagnet are heteropolar opposite to generate suction (such as Fig. 2 institute
Show), the retarding moment opposite with rotation direction is formed using the attraction between the first electromagnet and the second electromagnet, makes wheel disc
Slow down, (final speed can be controlled by controlling the working time of magnetic speed mechanism) after speed reduces to a certain extent,
The work of friction block stop mechanism carries out friction parking, and since the speed of wheel disc is lower, the temperature for the generation that rubs is relatively low, can
It improves braking efficiency and reduces the rate of wear of friction block.
Further, first electromagnet 1 is fixed in an annular mounting groove 5, the annular mounting groove and wheel disc 4 '
It is connected；Annular mounting groove is made of nonferromagnetic material (such as aluminium, copper, stainless steel).Since annular mounting groove is by nonferromagnetic material
It is made, will not be magnetized by the first electromagnet, it is ensured that the torque that the attraction between the first electromagnet and the second electromagnet generates
Always opposite with rotation direction.

Show.
When not braking, brush item is separated with conductive sheet, and when needing to brake, brush item is pressed to conductive sheet by actuator, thus
Corresponding first electromagnet is set to be powered, since the circumferential position of brush item is fixed, and in the rear side of the second electromagnet, therefore
It can guarantee only have several first electromagnet on rear side of the second electromagnet to be powered when brake, other first electromagnet is avoided to be powered but
Significant attraction can not be generated and waste electric energy.
Specifically, the actuator includes guide sleeve 3.2, the third electromagnet 3.3 of guide sleeve bottom is set, and sliding is set
The slide bar 3.4 in guide sleeve is set, the permanent magnet 3.5 of the lower end of the slider is connected to, and the attachment base at the top of slide bar is set
3.6；The brush item 3.1 is mounted on attachment base.When needing to brake, third electromagnet 3.3 is positive to be powered, at this time third electricity
Magnet is opposite with permanent magnet homopolarity to generate repulsion (as shown in Figure 3), so that pushing attachment base to move up connects the first electromagnet；It reduces
After the completion, third electromagnet is reversely powered, and third electromagnet and the heteropolar opposite generation suction of permanent magnet, retract slide bar at this time,
The power-off of first electromagnet, at this point, third electromagnet can also power off, permanent magnet can be sucked in the iron core of third electromagnet, avoid connecting
Seat is mobile, it is seen that when frame winch works normally, does not need consumption electric energy to maintain the retracted state of slide bar.
Further, the brush item 3.1 is carbon item, is detachable connection between brush item and attachment base 3.6.Due to
It can rub between brush item and conductive sheet, brush item is set as carbon item herein, can avoid conduction pad wear, and carbon item is
Wearing detail is replaced, therefore is set as detachable connection and is convenient for changing.In the present embodiment, opened up on attachment base 3.6
There is the mounting groove being adapted with brush item 3.1, brush item is plugged in mounting groove and locks by screw.
Preferably, arc-shaped extension 2.1 is provided at the top of the iron core of second electromagnet 2.The extension and ring
Shape mounting groove 5 with one heart, can expand the expanded range of pole on the second electromagnet by the extension, shorten the first electromagnet and second
The distance between electromagnet to improve total attraction, and then improves retardation efficiency.
Specifically, the friction block stop mechanism B includes two cylinders being oppositely arranged 8, and for fixing cylinder
Mounting base 9；The piston rod end of each cylinder is provided with one piece of brake block 10, and friction block 4, the wheel disc are equipped on brake block
It is arranged between two pieces of friction blocks.When brake, two piston rods stretch out simultaneously, and two pieces of friction blocks rub with wheel disc 4 ' simultaneously, and
