When above-mentioned hybrid brake system uses, during normal braking braking, hydraulic brake system plays brake action.Its process is for stepping on brake pedal, brake pedal force side exerts a force to the piston push rod of master cylinder, piston push rod overcomes the motion of internal reset spring force and carries out fluid power transmission, hydraulic coupling reaches in hydraulic chamber by conduit under fluid pressure, piston in promotion hydraulic chamber and brake clamp do relative motion, and then make the first friction lining and the second friction lining that the brake disc in it is compressed braking.When losing efficacy when the overheated vaporization of braking liquid, brake pedal is stepped under the complete continuation of hydraulic braking stroke, pull drag-line to drive piston pushing mechanism to promote piston, make the first friction lining and the second friction lining by the brake disc clamping braking in it by mechanical action, avoid braking failure.The piston pushing mechanism adopted, when stepping on brake pedal braking, drag-line drives pivoted arm to rotate, and rotates between push mechanism rotated by rotation ring and set collar, and then leans on the effect of ball by large for gap support between swivel becket and set collar.After brake pedal hydraulic braking stroke rotates, end, push mechanism position is covered hydraulic braking stroke clearance distance and is contacted with piston rod end.If now hydraulic brake system is malfunctioning, brake pedal is stepped under can continuing, and then push mechanism promotion piston rod is moved, and realizes brake.The piston pushing mechanism of this structure, adopts the structure of ball engagement to be convenient to the convert rotational motion of small distance be longer axial distance displacement, guarantees that its reliable transmission is stablized, while compact conformation is small and exquisite, have the advantage that braking is reliably sensitive.Pull back spring is for braking rear return.The structure of described push mechanism, conveniently by adjustment bolt, can regulate clearance distance that is inner and piston rod end, makes this distance can just and the stopping distance coupling of hydraulic brake system, reliably flexible to guarantee to brake.This structure also has the fixing very convenient advantage efficiently of installation simultaneously.
Even if lost efficacy to realize braking liquid in braking procedure in the present invention, the object that drg also can be braked, was connected brake pedal drag-line with mechanical braking arrangement.Like this, when under the effect of brake pedal at pedal force, hydraulic braking stroke is entered into from initial position, drg is in hydraulic state, and now, pivoted arm makes push mechanism start to contact with piston push rod under the pulling of drag-line, in this process, mechanical braking arrangement does not produce braking force.
When the temperature of braking liquid reaches braking liquid boiling temperature, braking liquid lost efficacy, brake pedal can continue to rotate under the effect of pedal force, namely mechanical braking distance can be entered from hydraulic braking stroke, brake pedal is while rotation, by the effect of drag-line, continue to pull pivoted arm to rotate, in the process, push mechanism promotes piston rod, make the first friction lining and brake disc, simultaneously, set collar promotes brake clamp and in the opposite direction makes the second friction lining and brake disc, thus, brake disc both sides produce friction force under the effect of two panels friction lining, reach the object of braking.
Drag-line of the present invention can adjust, and during adjustment, first unclamps fastening screw nut, can rotate freely adjustment bolt with hand; Then the power F that brake pedal one is downward is given, i.e. pin control effort, drg is made to be in braking mode, in promotion axle sleeve, adjusting bolt is rotated with hand, make the end contact of adjusting bolt end face and piston push rod, then enclose to inner rotary adjusting bolt n, make pitch P × n approximate C greatly, last fastening fastening screw nut.
Before braking failure, if need mechanical braking arrangement to participate in braking, after the end contact of adjusting bolt end face and piston push rod, rotation 1/2 can be lacked to inner rotary adjusting bolt and enclose, then fastening fastening screw nut.Use drg in the case, just achieve machinery and hydraulic pressure brakes object simultaneously, avoid the heat due to generation during braking and consequence that braking liquid was lost efficacy, ensure that the traffic safety of vehicle.
Therefore in above-mentioned hybrid brake system, hydraulic braking and mechanical braking are integrated in a brake system, make it possess good braking effect and the good feature of braking reliability simultaneously; Also have compact conformation, stable transmission, stopping distance is the advantage such as adjustable flexibly simultaneously.
