Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1 to 4, the present invention discloses a wheel and engine linked brake structure, including a first brake 300 and a second brake 400 respectively disposed on two wheels, and a foot brake 100 simultaneously connected to the first brake 300 and the second brake 400, further including:
and a third brake member 500 provided at the engine and connected to the foot brake 100 for locking or unlocking the power output of the engine.
When the existing automobile brakes, only the first brake piece 300 and the second brake piece 400 brake two wheels, and the engine continues to keep the original speed movement, so that the existing automobile can resist the deceleration process of the wheels. In this application, set up third brake piece 500, and third brake piece 500 is connected with service brake 100 simultaneously, and when triggering service brake 100, first brake piece 300 and second brake piece 400 brakies two wheels, and third brake piece 500 brakies the engine simultaneously, has avoided the engine to keep original rotational speed and has produced the influence to the deceleration process of wheel, has shortened the braking distance of car (has reduced the brake time of car).
The third brake 500 has a first brake end 501 and a second brake end 502, the foot brake 100 is connected to the first brake end 501;
the hand brake 200 is connected with the second brake end 502;
the foot brake 100 and the hand brake 200 can brake the engine independently.
When the automobile is stationary, the driver usually pulls the hand brake to prevent slipping, in this application, the hand brake 200 is connected to the second brake end 502 of the third brake member 500, and the engine is locked to lock the wheels to prevent slipping.
The third brake member 500 includes: a follower disk 510 fixed to a rotation shaft of the engine and rotating with the rotation shaft; a first brake block 520 and a second brake block 530 oppositely arranged on the peripheral side of the follower disk 510, wherein the first brake block 520 and the second brake block 530 are respectively provided with a friction part 521 which can be attached to the follower disk 510, and pressing parts 522 which are formed by extending two ends of the friction part 521 in the direction away from each other;
the two pressing parts 522 at the same end of the friction part 521 form a first brake end 501, and the two pressing parts 522 at the other end of the friction part 521 form a second brake end 502;
the two pressing portions 522 of the first brake end 501 or the second brake end 502 can drive the two friction portions 521 to cling to the follower disc 510 to lock the rotation of the follower disc 510 when moving in a direction of approaching each other.
Specifically, the follower disk 510 is fixed to a rotating shaft of the engine (an output shaft or other transmission shaft connected thereto), and a first brake pad 520 and a second brake pad 530 are disposed on the circumferential side of the follower disk 510 to restrict or unlock the rotation of the follower disk 510, thereby realizing braking of the engine and the transmission shaft connected thereto; the friction portion 521 of the first brake pad 520 and the second brake pad 530 is an arc-shaped body with elasticity, and the radian of the friction portion 521 is greater than or equal to the outer edge radian of the follower disk 510. When the pressing part 522 at the same end is pressed, the friction part 521 can be tightly attached to the outer edge of the follower disk 510 so as to limit the rotation of the follower disk 510; when the two pressing portions 522 are released, the friction portion 521 is lifted off the follower disk 510 and does not restrict the rotation of the follower disk 510. Therefore, the first brake end 501 and the second brake end 502 can brake the follower disc 510 independently, and the hand brake 200 and the foot brake 100 can brake the engine independently.
Two of the first brake end 501 are provided with a driving oil cylinder 540 between the pressing portions 522, and the driving oil cylinder 540 extends and retracts to drive the two pressing portions 522 to move away from or close to each other.

the elastic pressing part 522 further comprises a guide rod 550, wherein two ends of the guide rod 550 are respectively penetrated through any fixing through hole 522a of the pressing part 522, and a return spring 560 is sleeved on the guide rod 550.
As shown in fig. 3-4, the pressing portion 522 has three fixing through holes 522a along the length direction thereof, and the guide rod 550 is selectively inserted into any one of the fixing through holes 522a, so as to adjust the ratio of the braking force to the moving stroke of the pressing portion 522.
The middle of the guide rod 550 is provided with a positioning block 551, two ends of the guide rod 550, which are positioned at the positioning block 551, are respectively sleeved with a spring 560, and one end of each of the two springs 560 abuts against the abutting piece.
The positioning block 551 is provided with a hole for fixing.
As shown in fig. 2, the positioning block 551 is disposed at the midpoint of the guide rod 550, so that the pretightening force provided by the springs 560 at the two ends of the positioning block 551 is the same, and the moving strokes of the two pressing portions 522 are the same, and finally the braking forces of the first brake pad 520 and the second brake pad 530 on the follower disk 510 are the same.
