The invention provides a ratchet brake device of a two-section vehicle, and relates to a ratchet brake device of a two-section vehicle. The ratchet brake device comprises a pawl and a ratchet, and theratchet is of a gear structure and can rotate around a central shaft of the ratchet. The pawl is of an L-shaped structure, and the head of the pawl is matched with the tooth part of the ratchet so that when the head of the pawl enters the ratchet, the pawl can prevent the ratchet from rotating; the L-shaped leg part of the pawl is respectively connected with a tension spring and a reset spring; the tension spring is used for pulling the pawl so that the head of the pawl enters the ratchet; the reset spring is used for pulling the pawl so that when the tension spring does not pull the pawl, the head of the pawl leaves the ratchet. According to the invention, reliable and rapid parking braking can be carried out on the double-section vehicle.
一种双节车棘齿制动装置,涉及一种双节车棘齿制动装置,包括棘爪和棘齿,所述棘齿为齿轮结构,能够围绕其中心轴进行旋转;所述棘爪为L形的结构,其头部与所述棘齿的齿部配合,使得当所述棘爪的头部进入到所述棘齿内时,所述棘爪能够阻止所述棘齿旋转;所述棘爪的L形的腿部分别连接拉力弹簧和复位弹簧;所述拉力弹簧用于拉动所述棘爪,使得所述棘爪的头部进入到所述棘齿内;所述复位弹簧用于拉动所述棘爪,使得在所述拉力弹簧不拉动所述棘爪时,所述棘爪的头部离开所述棘齿。本发明可以实现对双节车辆进行可靠、迅捷的驻车制动。
