The invention relates to a shaft end speed and temperature measurement grounding integrated device, a bogie comprising the shaft end speed and temperature measurement grounding integrated device and an urban rail vehicle, and belongs to the technical field of rail traffic equipment. The integrated device comprises a front-section flange, a body, a grounding assembly and a plurality of sensors, the front-section flange comprises a center shaft and a flange plate, and one side of the flange plate is used for making contact with the axle end of an axle. The body is rotationally connected to the central shaft, an accommodating cavity is formed in the body, a wiring port and a plurality of interfaces are formed, and a cantilever is arranged on the periphery of the body; the grounding assembly comprises a friction disc gear assembly, a brush carrier and a carbon brush; the friction disc gear assembly comprises a wheel seat connected to the center shaft, a speed measuring gear is arranged on the periphery of the wheel seat, and a friction disc is installed on the speed measuring gear. The brush carrier is installed on the cavity wall of the containing cavity and provided with wiring points. The carbon brush is mounted on the brush holder, and one end is contacted with the friction disc; the plurality of sensors are installed on the plurality of interfaces in a one-to-one correspondence manner. The shaft end speed measurement, temperature measurement and grounding integrated device has the functions of vehicle speed measurement, shaft temperature monitoring and grounding conduction at the same time.
