Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-5, a kind of self-adapting type brake device for car, including frictional disk 1, fixed disk 2,3 and of linkage mechanism
Arrestment mechanism 4, the positive middle part of frictional disk 1 are movably installed with fixed disk 2, and the bottom of the positive side of fixed disk 2 is fixedly installed with
One end of linkage mechanism 3, linkage mechanism 3 is equipped with arrestment mechanism 4.
Wherein, the heat release hole of annular permutation arrangement is offered in the outer lug boss of frictional disk 1, to prevent frictional disk 1 from braking
During temperature it is excessively high, and the case where cause its brake efficiency to weaken.
Wherein, it is sequentially connected between frictional disk 1 and fixed disk 2 by bearing and copper sheathing, so that frictional disk 1 is with axle height
When speed rotation, fixed disk 2 will not rotate together with frictional disk 1.
Referring to Fig. 6, in the technical program, linkage mechanism 3 include linkage oil cylinder 31, kinematic link 32, driving disk 33,
Secured adjusted axis 34 and gag lever post 35, the back side for the oil cylinder 31 that links are threadedly coupled with the front of fixed disk 2, linkage oil cylinder 31 and biography
It is sequentially connected between dynamic disk 33 by kinematic link 32, and the side outside kinematic link 32 is fixedly installed with secured adjusted axis
34, the outer surface of secured adjusted axis 34 is contacted with the outer wall of gag lever post 35, and one end of gag lever post 35 and fixed disk 2 positive one
Side is fixedly connected.
Wherein, the inside of secured adjusted axis 34 is equipped with the adjusting block of pyramidal structure, and the two sides of taper adjusting block pass through two
Group nut is fixedly mounted.
Referring to Fig. 7, arrestment mechanism 4 includes that cam connects block 41, connecting rod 42, adjustable shelf 43 and system in the technical program
Dynamic hoof 44, cam connect the bottom end of block 41 and the back side pin joint of driving disk 33, and cam, which connects, passes through company between block 41 and adjustable shelf 43
Extension bar 42 is sequentially connected, and the inside of adjustable shelf 43 is fixedly installed with brake-shoe 44.
Wherein, pass through the position of adjusting taper adjusting block, so that it may drive driving disk 33 to rotate, and then adjust system
Gap size between dynamic hoof 44 and frictional disk 1, and the regularly adjustment to 44 gap of brake-shoe, can be always maintained at the braking
Device has good brake efficiency.
Wherein, the minimum stroke of linkage oil cylinder 31 is greater than the gap between brake-shoe 44 and frictional disk 1, to ensure braking
Shi Liandong oil cylinder 31 has enough strokes to drive 44 clamping frictional disk 1 of brake-shoe.
Wherein, the setting of secured adjusted axis 34 and gag lever post 35 can effectively control cam when loosening the brake
The even gap between block 41 and brake-shoe 44 and frictional disk 1, the degree for preventing arrestment mechanism 4 from falling is excessive, and cam is caused to connect
It rubs between block 41 and the inner wall of frictional disk 1, causes locked situation.
Referring to Fig. 7, in the technical program, brake-shoe 44 is using arc surface wedge structure, and 44 inside of brake-shoe
Radian is less than the radian of 1 outer surface of frictional disk.
Wherein, for the setting of 44 arc surface wedge structure of brake-shoe and its angle, can make under the turning effort of frictional disk 1
It has the tendency that along direction of rotation clamping, so that the device, during braking, the faster brake force of speed will be stronger.
The application method and working principle of the present embodiment:
Firstly, the brake apparatus is fixedly mounted on the main shaft of automobile, when automobile needs to brake, driver is stepped on
Brake pedal, hydraulic oil will be sent in linkage oil cylinder 31 by hydraulic output device, and band under the action of kinematic link 32
Dynamic driving disk 33 rotates, and band moving cam connects block 41 and shifts, and is in contact with the inner wall of frictional disk 1, while
The linkage effect of arrestment mechanism 4 is lower to drive adjustable shelf 43 and brake-shoe 44 to deviate and contact inwardly with the outer wall of frictional disk 1, into
And clamping frictional disk 1 forms automobile and brakes, and under the turning effort of frictional disk 1, cam connects the interior of block 41 and frictional disk 1
Wall contact when, will lead under the action of frictional force cam connect block 41 have along 1 rotation direction of frictional disk rotate trend, into
And the further clamping frictional disk 1 of brake-shoe 44 is driven, when the speed that frictional disk 1 rotates is faster, cam connects block 41 along its turn
The trend and degree in dynamic direction are stronger, and then connect block 41 to the inner wall of frictional disk 1 and brake-shoe 44 to rubbing with moving cam
Wipe disk 1 outer wall card will be tighter so that the brake force of the brake apparatus is stronger, the automobile to run at high speed is provided enough
Brake force, with promote allow to stopping of timely slowing down；
And when loosening the brake, linkage oil cylinder 31 loses the pressure of hydraulic oil, the reset spring in linkage oil cylinder 31
Under effect, block 41 is connected with moving cam by kinematic link 32 and is turned round, and then unclamped cam and connect block 41 and brake-shoe 44 to frictional disk 1
Snap action, while under the blocking of secured adjusted axis 34 and gag lever post 35, can keep the cam after unclamping connect block 41 and
Brake-shoe 44 is on certain position, is being braked with ensuring that cam connects the gap between block 41 and brake-shoe 44 and frictional disk 1
Front and back will not change, and keep the braking effect of the brake apparatus, and when cam connects block 41 and brake-shoe 44 and frictional disk 1
Between gap it is excessive or too small when, the upper and lower position of taper adjusting block is adjusted by loose nut, and drives driving disk
33 occur a degree of deflection, so that the gap that cam connects between block 41 and brake-shoe 44 and frictional disk 1 changes,
It is adjusted to suitable clearance distance, entire set-up procedure is simple and convenient.
