Low-floor vehicle, bogie and axle end structure of bogie

Abstract

The invention discloses a low-floor vehicle, a bogie and an axle end structure of the bogie. The axle end structure comprises a speed measuring gear and a friction disk, wherein the speed measuring gear with a middle through hole is used for being fixedly connected to the end surface of a wheel; the outer end surface of the speed measuring gear is provided with a plurality of speed measuring teethuniformly distributed in the circumferential direction; the friction disk is fixedly connected to the speed measuring gear, and specifically configured on the outer end surface of the speed measuringgear and on the radial outer circumference of the speed measuring teeth; an axle end front cap is mounted on the outer sides of the speed measuring gear and the friction disk in a covering manner; abody central part of the axle end front cap is used for being fixedly connected to an axle end of a vehicle axle through the middle through hole of the speed measuring gear; and a speed sensor interface and a brush interface which are separately arranged corresponding to the speed measuring teeth and the friction disk are formed on the axle end front cap. The axle end structure of the bogie is optimized, and the space of the axle end is fully utilized to integrate the functions of grounding and speed measuring into the axle end of the bogie; and the axle end structure of the bogie is simple and reliable in structure, and further reduces the difficulty of wiring while reducing the design complexity of the bogie.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a low-floor vehicle, a bogie and an axle end structure thereof. Background technique [0002] As we all know, low-floor vehicles are widely favored for their simple structure and strong adaptability to the environment. However, in the design process of a low-floor vehicle, on the one hand, the axle end has a compact structure, a small space, and relatively many functional requirements, and there are certain design difficulties in the arrangement of the axle end speed sensor and the grounding device. The solution in the prior art is to arrange different sensors at different axle ends of the bogie respectively. Due to the limitation of its own structure, this solution increases the complexity of the whole bogie and also increases the difficulty of vehicle wiring. [0003] In view of this, it is urgent to find another way to optimize the design of the bogie axle end of the low...
