Abstract
The utility model discloses a combined mechanical contracting brake, which solves the problem that the current contracting brake during braking cannot full contact the brake pulley. The structure of the utility model is that the braking lever 3 is installed through the pin roll B inside the brake frame 2, the end (A) of the braking lever 3 is connected to the brake cable 8, and the other end (C) is connected to the brake band 4. The inner side of the brake band 4 is equipped with the vehicle braking band 6. The brake band 4 circles around the braking wheel 1. The utility model is characterized in that the other end of the brake band 4 is hinge jointed to the pin roll D of the auxiliary force supporter 5. The auxiliary force supporter 5 is hinge jointed to the brake frame 2 through the pin roll E. The pin roll E and the brake band 4 are beneath the pin roll D. The contracting brake under the effect of the brake band exerts pressures on the End C of the brake band 4 and meanwhile the end D of the bank band 4 exerts pressures on the brake wheel 1. The two ends of the brake band 4 joint and exert pressures to the center part of the brake wheel 1 to move the brake wheel 1, which narrows the brake band opening and embraces the partial surface of the brake wheel 1, therefore the braking effect is improved.
Description
Technical field
The utility model belongs to the drg technical field.
Background technology
Existing mechanical brake---band-type brake, its structure are that a strap of the brake that is fixed with brake band on it is installed in the lock frame, it be centered around brake wheel around, the one end is fixed on the lock frame, the other end is stressed movable end.Glancing impact, the stressed movable end of the strap of the brake moves forward under tension, makes the strap of the brake lean on the half-turn of stressed movable end to be close on the brake wheel, but because the other end of the strap of the brake is fixed on the lock frame, can not move, cause the strap of the brake to lean on the half-turn of fixed end can not play brake action, so braking effect is poor.
Summary of the invention:
In order to solve the shortcoming that existing band-type brake exists, the utility model proposes following design plan, referring to accompanying drawing.
A kind of combined type mechanical hatching gate, the strap of the brake 4 that its inboard is fixed with brake band 6 is installed in lock frame 2, the strap of the brake 4 be centered around brake wheel 1 around, its end is stressed movable end, the other end that it is characterized in that the strap of the brake 4 is hinged on the bearing pin D of power-assisted support 5, power-assisted support 5 is hinged on the lock frame 2 by bearing pin E, and the bearing pin E and the strap of the brake 4 all are positioned at the below of bearing pin D.
Apply pulling force for the ease of the stressed movable end to the strap of the brake 4, by bearing pin B restrictor bar 3 is installed in lock frame 2, an end of restrictor bar 3 (A end) links to each other with brake cable 8, and the other end (C end) connects the strap of the brake 4.Brake cable also can be replaced by pull bar.
Glancing impact, the stressed movable end of the strap of the brake 4 moves forward under tension, half-turn brake band 6 is close to brake wheel 1 before making, the other end D of the strap of the brake 4 also moves forward along brake wheel 1 simultaneously, and it is centroclinal to brake wheel around hinge E to drive power-assisted support 5, and brake wheel 1 is produced pressure and friction force, cause D end brake band 6 to be adjacent to brake wheel 1, so the two ends of the strap of the brake 4 (movable force side and D end) the compound while is mobile to the pressurization of brake wheel center, dwindle the opening of the strap of the brake 4.Do not only depend on the brake band 6 of stressed movable end half-turn to hug brake wheel 1 like this, its back half-turn brake band 6 by the D end also hugs brake wheel 1, so braking effect strengthens.Bearing pin E is far away more apart from the center of circle O of brake wheel 1, and its braking force is big more.This combined type mechanical hatching gate is simple in structure, easy to maintenance.
The utility model can be used for vehicle and mechanical equipments such as bont (as winch, winch) and conveyer such as bicycle, train, automobile.
Description of drawings:
Accompanying drawing is the embodiment full sectional view.
The specific embodiment
Narrate embodiment with reference to the accompanying drawings.
A kind of combined type mechanical hatching gate that is used for bicycle is installed its inboard fixedly strap of the brake 4 of brake band 6 in lock frame 2, the strap of the brake 4 be centered around brake wheel 1 around, the one end is stressed movable end.In lock frame 2, restrictor bar 3 is installed by bearing pin B, one end of restrictor bar 3 (A end) links to each other with brake cable 8, the other end (C end) connects the stressed movable end of the strap of the brake 4, the other end that it is characterized in that the strap of the brake 4 is hinged on the bearing pin D of power-assisted support 5, power-assisted support 5 is hinged on the lock frame 2 by bearing pin E, and the bearing pin E and the strap of the brake 4 all are positioned at the below of bearing pin D.On lock frame 2, install and adjust Luo Ding 7, be convenient to adjust the gap between brake band 6 and the brake wheel 1.Glancing impact, under manually brake cable 8 spurred, restrictor bar 3 rotated around bearing pin B, drove the strap of the brake 4 and moved forward, and exerted pressure by 6 pairs of brake wheels 1 of preceding half-turn brake band, produced friction force.Simultaneously, the upper end of power-assisted support 5 (D end) tilts to the brake wheel center O under the drive of the strap of the brake 4, makes back half-turn brake band also produce pressure and friction force to brake wheel.Like this, moving, pressurize to the center O of brake wheel 1 simultaneously in the two ends of the strap of the brake 4, dwindles strap of the brake mouth, makes brake band 6 hug brake wheel 1, strengthens braking effect.
