Four gear coordinated types braking clearance adjustment device

Four gear coordinated types braking clearance adjustment device combines manual guiding mechanism and main guiding mechanism's function, and main guiding mechanism possesses manual clearance adjustment function and initiative clearance adjustment function, nevertheless do not combine with adjustment screw, only performance adjustment and antioverloading function, driven guiding mechanism increases to two, two push rods with combine from guiding mechanism, realize from guiding mechanism that pair push rods move under main guiding mechanism's drive. This kind of structure, main guiding mechanism combines with the pressure arm, just realize adjustment and antioverloading function, and it is not in relevancy with the screw rod, combine together from guiding mechanism and two adjustment screw, avoided taking place locking or jamming phenomenon because the guiding mechanism disabler results in being connected the position with adjustment screw, homophony or from transferring the function to have any trouble no matter, do not influence whole brake mechanism's normal work, no matter can guarantee any condition, the brake is all normal effective, and will follow the guiding mechanism structure and simplify, the depth of parallelism that makes the braking promotes with stability greatly.
