7 movements；The drive rack 7 of movement will drive driving gear 6 to move；Driving gear 6 will drive fixing axle 5 to move；It is fixed
Axis 5 will move under the guiding function of third screw thread 29；Fixing axle 5 will be by the second screw thread 28 and the first actuating sleeve 16
Screw-internal thread fit, to achieve the purpose that drive the first actuating sleeve 16 moved along the first guide groove 34；First actuating sleeve of movement
16 will drive the first fixed ring 9 to move；First fixed ring 9 of movement will drive the first spring 18 to move；First spring 18
First brake piece 10 will be driven to move；First brake piece 10 at this time will be with 4 frictional fit of brake disc；Automobile at this time will
Will can slowly it slow down under 4 rubbing action of brake disc in first brake piece 10；When driver's an emergency situation is encountered hard braking,
The fixing axle 5 moved at this time will drive the first screw thread 27 to move, and the first screw thread 27 will be moved with the second actuating sleeve 13；Second
Actuating sleeve 13 will drive the second fixed ring 14 to move；Second fixed ring 14 will drive second spring 12 to move；Second spring
12 will give 11 1 active forces of the second brake block；The second brake block 11 at this time will be simultaneously to brake with first brake piece 10
4 active force of disk, so automobile at this time will quickly reduce vehicle under the action of first brake piece 10 and the second brake block 11
Speed, to achieve the purpose that heavy brake automobile；When the custom that driver drives is relatively good, light brake of driving often, brake block warp
The only first brake piece 10 being often worn；When the time that first brake piece 10 uses is longer, driver is gently used in brake
There is failure because of prolonged abrasion in first brake piece 10, at this time if it is also that can ensure to drive a vehicle that driver, which stops by force,
Safety, because the second brake block 11 does not occur the phenomenon that wear out failure.The failure of vehicle braking mechanism gently stopped can be to
The prompt of one replacement brake block of driver, but brake block used in the strong brake of vehicle braking mechanism has not expired at this time, from
And achieve the purpose that protect driver.Present invention utilizes the light brake block stopped and worn in a flash by force is different so that Ren Menneng
Enough in light brake failure, replacement brake block can either be had recognized the need to, and can continue to drive safely using brake by force.In addition brake block
When mounted, gently the working face of brake block can install slightly more secondary brake block in a flash, and in the work of brake block in a flash by force
The safety for improving vehicle braking can be done so, while ensure that economy with the higher brake block of installation quality by making face；
The purpose of automotive safety can be taken into account again while ensureing economy in this way.
In conclusion the above embodiment is not the restricted embodiment for being the present invention, all those skilled in the art
On the basis of the substantive content of the present invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as this
The protection domain of invention.
