SYSTEM OF SAFE BRAKING WITH DOUBLE CLUTCH Russian patent published in 2020 - IPC B62L3/02 

FIELD: transport machine building.

SUBSTANCE: present invention relates to safety system with double clutch, which includes at least brake handle, base, rear wheel brake cable, front wheel brake line, rear wheel brake and front wheel brake. Said brake handle is equipped with first connecting rod and second connecting rod, drive lever of brake handle is equipped with hole of first shaft and opening of second shaft; hole of the second shaft represents an elongated hole in the form of arc, distance between the opening of the first shaft and shaft 200 is less than the distance between the hole of the second shaft and the shaft. First support shaft rotates between the opening of the first shaft and the first connecting rod, and the outer side of the first connecting rod is connected to the brake cable of the rear wheel. Second support shaft rotates between the second shaft bore and the second connecting rod, and the second connecting rod outer side is connected to the front wheel brake cable.

EFFECT: therefore, the driver only needs to press the brake once to derive the time difference brake force by the first connecting rod and the second connecting rod, and rear wheel brake and front wheel brake can generate braking action with time difference; besides, the length of the movable arc of the second connecting rod is greater than the length of the moving arc of the first connecting rod during rotation of the drive lever, therefore, braking force generated by second connecting rod is greater than braking force of first connecting rod, and braking force of front wheel brake is greater than braking force of rear wheel brake, which is important to achieve safe braking goal, and can prevent accidents caused by the fact that the driver usually starts the front wheel brake first.
