Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The present invention is mainly applied to two-way trackless trains (such as rubber-tyred low-floor intelligent rail trains). The whole body is 35 meters long. A cab is provided, and the entire vehicle can realize two-way driving.

[0014] Such as figure 1 As shown, the parking brake system of the rubber-tired low-floor intelligent rail train of the present invention, because the train includes a plurality of carriages and cabs located at both ends of the head and tail, so the train includes N axles, and N is a natural number; The invention includes two sets of parking actuators, respectively corresponding to the cabs at the first and last ends of the train, so as to ensure that the parking brake operation can be completed in each cab. The parking actuators are connected to each axle through the brake pipeline The brake air c...

Abstract

The invention discloses a parking brake system of a rubber-wheel low-floor intelligent rail train. The train contains a plurality of carriages and cabs at the head and tail of the train; the train comprises N axles; the parking brake system comprises two sets of parking execution mechanisms respectively corresponding to the cabs at the head and tail of the train; the parking execution mechanisms are connected with a brake chamber on each axle through brake lines; parking brake spring chambers are arranged at the second axle and (N-1)th axle of the train and are connected with two parking execution mechanisms through the brake lines; and when one of the two parking execution mechanisms is in a parking brake gear, no high pressure gas exists in the parking brake spring chambers at the second axle and the (N-1)th axle, and the second axle and the (N-1)th axle are in a brake state. The parking brake system disclosed by the invention has the advantages of simple and compact structure, convenient operation, good reliability and the like.

Description

technical field [0001] The invention mainly relates to the field of urban public transport equipment, in particular to a parking brake system for rubber-tyred low-floor intelligent rail trains. Background technique [0002] Urban rail transit refers to a special-line public transportation system with continuous guiding capabilities, which is characterized by having a specific track and vehicles running along the track. Common urban rail transit includes subways, light rails, and trams. Among them, subways and light rails are mostly built underground or on viaducts, and they can run freely in special rail lines by using the blocking mode. Although they have a strong transportation capacity, the initial infrastructure and vehicle purchase costs are relatively high, making them unavailable in small and medium-sized cities. application. Trams require a special power system and track coordination design, whether the design and construction costs or maintenance costs are relativ...
