Abstract

The invention provides a gear box and a rail vehicle. The gear box is provided with a box body, a transmission assembly and an oil pump. The transmission assembly includes a driving gear and a driven gear arranged in the box body. The oil pump is arranged in the box body. The oil pump includes a The oil component and the pump gear, the oil delivery component is used for oil suction and oil discharge, the pump gear is drivingly connected with the oil delivery component, the driven gear meshes with the pump gear to drive the pump gear to rotate, and the oil suction port of the oil pump is in contact with the oil storage area of ​​the tank connected to absorb lubricating oil, and the oil outlet is used to supply oil to the predetermined part of the transmission assembly for lubrication; and when the oil pump is in the first operating state and the oil pump is in the second operating state, the lubricating oil is in the oil pump along the same The preset path flows; the oil pump is in the first running state when the driving gear is rotating forward, and the oil pump is in the second running state when the driving gear is rotating reversely. The technical solution can simplify the structure of the gearbox, reduce the size and weight, and realize light weight.

Description

technical field [0001] The invention relates to the technical field of gear boxes, in particular to a gear box and a rail vehicle. Background technique [0002] The traditional rail transit gearbox mainly adopts the lubrication method of splash lubrication. With the increasing research and development of various new rail transit vehicles, the structural types of rail transit gearboxes are becoming more and more diverse. For the higher parts in the gearbox or the relatively independent internal space, the traditional splash lubrication method can no longer meet the internal lubrication needs. Therefore, in the field of rail transit or other fields with high lubrication requirements, there is a demand for forced lubrication of gearboxes. [0003] In order to realize forced lubrication, there is a lubrication scheme in which an oil pump is installed outside the gear box in the prior art. This scheme requires an additional oil pump drive device and control device, which not on...
