Patent ID: 8794391

Claim:
A safety braking system mounted to a linear two-wheel vehicle and having a right brake lever and a left brake lever to respectively control applying a brake to a front wheel and a rear wheel of the vehicle, comprising: a safety brake connected between the right and left brake levers and the front and rear wheel brakes, whenever either the right brake lever or the left brake lever is pulled, the safety braking system controls the rear wheel brake to be activated before the front wheel brake to be activated, at least one primary mechanism and a secondary power transmission mechanism, the left and right brake levers connected to the primary mechanism which transfers a braking force generated from either the left or right brake levers to the secondary power transmission mechanism, the secondary power transmission mechanism transfers the braking forces to the front and the rear wheel brakes, to control the rear wheel brake to be activated first and then the front wheel brake to be activated in sequence, wherein the safety braking system comprises two plates which are the primary mechanism, the two plates each have a through hole, a transition portion extends through the through holes so as to connect the two plates, the plates each have a brake cable hole and a brake cable positioning portion which is located at an end where the through holes are defined, brake cables of the left and right brake levers extend through the two brake cable holes to connect the two plates, multiple lead cable holes are defined in an other end of the plates and located opposite to the through holes, the lead cable holes are located in radial direction relative to the through holes, a lead cable of the front wheel brake extends through the lead cable holes that are located close to the through holes, a lead cable of the rear wheel brake extends through the lead cable holes that are located remote from the through holes so as to connect the two plates and to form the secondary power transmission mechanism.
