The principle of this programme reel brake unit is:
When Hydraulic Cylinder push rod is downward, the distance between push rod and caliper is gradually reduced；Then go up small end and
Distance between lower link lower end reduces, and therefore goes up connecting rod and lower link by the pin joint bending mutual along it；I.e. lower link turns
Dynamic, drive caliper to rotate simultaneously, so that caliper clamps track, reach braking effect.When push rod moves up, on
Distance between small end and lower link lower end is gradually increased, and therefore goes up connecting rod and lower link will be stretched, and caliper is anti-
Track is unclamped so that vehicle derailing on-position to rotation.
This programme produces and provides the benefit that:
(1), in this programme, by link gear, the power of hydraulic cylinder being delivered to caliper, link gear is multi link
Articulated structure, because structure and power transmission are the most more stable.
(2), this link gear be parallel-crank mechanism, therefore the maximum rotation angle of each connecting rod can be made close to 90
The rotational angle of dynamic pincers is also up to 90, thus beneficially the hiding of caliper.
(3), owing to link gear is parallel-crank mechanism, therefore link gear is during being compressed downwardly, edge
The power in upper connecting rod and lower link direction will be gradually increased so that is exaggerated driving force, i.e. link gear has the gain effect of power,
Therefore link gear can strengthen braking effect.
Preferred version one: as the further optimization to base case, described hydraulic cylinder is provided with back-moving spring, reset bullet
Spring is set on push rod, and the lower end of hydraulic cylinder is provided with spacing end cap.When making vehicle derailing on-position, required power is less,
