Abstract

The invention provides a gear box, a bogie and a railway vehicle. The gear box comprises a box body, an input gear shaft and a speed measuring device; a first end of the input gear shaft penetrates through the box body and is suitable for being connected with a driving mechanism, and a second end of the input gear shaft extends to the outer side of the box body; and the speed measuring device is installed at the second end of the input gear shaft and located on the outer side of the box body. According to the gear box provided by the invention, a series of work such as vehicle lifting, wheel falling and wheel withdrawing does not need to be carried out during decomposition inspection, the box body of the gear box does not need to be disassembled, and the speed measuring device can be disassembled on the outer side of the box body of the gear box, so that the gear box is convenient and rapid, and the decomposition inspection cost is lower.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a gear box, a bogie and a rail vehicle. Background technique [0002] At present, some rail vehicles integrate the traction speed sensor in the gearbox. Occasionally, the speed signal is lost or abnormal during the operation of the rail vehicle, and oil leakage from the installation surface of the speed sensor is also prone to occur. In order to check the source of the fault, it is usually necessary to disassemble the relevant components and check the geometric dimensions of the speed measuring gear. Since the speed measuring gear paired with the speed sensor is integrated in the gear box, it is necessary to fully disassemble the input shaft of the gear box. In this case, it is necessary to lift the car, drop the wheel and retract the wheel, and the amount of decomposition is relatively large. Moreover, the restoration of the gearbox requires re-injection of expensive synt...
