Abstract

이 발명은 주차 브레이크용 제어장치에 관한 것으로서, 브레이크 케이블의 스트로크 손실의 범위내에 상당하는 브레이크 해제 상태에 있는 조작레버의 조작 당초에 있어서, 적당한 여유와 절도있는 조작감이 얻어지는 것을 목적으로 한 것이다.The present invention relates to a control device for a parking brake, which aims at obtaining a suitable margin and a modest feeling of operation in the beginning of operation of a control lever in a brake release state corresponding to a stroke loss of a brake cable.

래칫치(112)의 브레이크 해제측의 최끝단 노치부(112a)에 계속하여 부채 형상 고정부(111)의 바같둘레부에 형성되는 발톱(114)의 유도부(2)가 절곡부(2a)를 가지는 절곡면으로서, 조작레버(103)의 브레이크 상태를 얻는 방향(a방향)의 회동에 의한 발톱(114)의 절곡부(2a)의 통과로, 걸어맞춤부재(113)에 힘이 가해지는 반대방향 (d방향)으로의 회동량을 증대시켜서, 걸어 맞춤부재(113)에 힘을 가하는 스프링 부재(117)의 스프링 하중을 급격하게 증대시키는 절곡면을 가져 헐성되어 있다.Following the bent portion 112a of the end of the ratchet 112 on the brake release side, the guide portion 2 of the toenail 114 formed on the bar circumferential portion of the fan-shaped fixing portion 111 forms the bent portion 2a. The branch is a bent surface, in which the force is applied to the engaging member 113 by the passage of the bent portion 2a of the claw 114 by the rotation in the direction (a direction) of obtaining the brake state of the operating lever 103. The bending amount which increases the amount of rotation in the direction (d direction) and rapidly increases the spring load of the spring member 117 which exerts a force on the engagement member 113 is loosened.

Claims

The ratchet mechanism for controlling the rotation of the operating lever connected to the brake mechanism via the brake cable is provided with a fan-shaped fixing portion having a latch formed at the outer circumference thereof, and a toenail fitting to the ratchet. It is pivotally supported on the lever and is connected to the release button, and is also a latching member that is applied by the springing force to the ratchet in the barbering direction, and continues to the last notch on the brake release side of the ratchet. The engaging member is a bending surface having the bent portion of the guide portion formed on the outer circumferential portion of the fan-shaped fixing portion, and the engaging member passes through the bent portion of the toenail by rotation in the direction of obtaining the brake state of the operating lever. By increasing the amount of rotation in the opposite direction to which the force is applied Parking brake control device, characterized in that the bending surface is increased to increase.

2. The bent surface according to claim 1, wherein the bent surface is formed of a first inclined surface formed by downward gradient of a steep gradient following the end notch and a second inclined surface formed by a downward slope of a toy gradient subsequent to the first slope. Parking brake control device, characterized in that.
