Problems solved by technology

As a key component of the lubrication of the axle gearbox, the lubrication pump provides lubrication for the bearings and gears inside the axle gearbox. It should meet the needs of different operating conditions of rail vehicles. Most of the existing axle gearbox lubrication pumps are one-way lubrication. Its reliability and vehicle operation safety are poor

Abstract

The invention provides a gearbox lubricating pump used for a rail vehicle. The gearbox lubricating pump comprises a suction filter, an oil pump and an oil pump gear, wherein the oil pump comprises an oil pump shell; the suction filter is fixedly connected with the lower end surface of the oil pump shell; the oil pump shell comprises a ball valve chamber, a pump body and a gearbox; the ball valve chamber and the gearbox are separately arranged at the two sides of the pump body and are fixedly connected with the pump body; a gear pair is supported in the pump body through a gear shaft I and a gear shaft II; one end of the gear shaft I penetrates through the gearbox; and the oil pump gear is fixedly arranged on the gear shaft I. Driven by the oil pump gear, the clockwise and counterclockwise rotating of the gear pair can both produce forced lubrication, so that the lubricating pump rotates at different speeds when the vehicle is at different speeds, can perform a function of forced lubrication through both clockwise and counterclockwise rotating, can meet the lubrication of the axle gearbox no matter when the rail vehicle runs forwards, backwards or at different speeds and greatly improves the reliability of the axle gearbox and the running safety of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of railway rail vehicles, and in particular relates to a gearbox lubricating pump for rail vehicles. Background technique [0002] The axle gearbox is an important part of the vehicle's running transmission system. It is a transmission mechanism used to transmit power, change the torque and speed of external input, and adapt to the operating requirements of the vehicle under different working conditions. Its performance directly affects the vehicle. safe use. As a key component of the axle gearbox lubrication, the lubrication pump provides lubrication for the bearings and gears inside the axle gearbox. It should meet the needs of different operating conditions of rail vehicles. Most of the existing axle gearbox lubrication pumps are one-way lubrication. Its reliability and vehicle operation safety are poor. Therefore it is necessary to propose improvements. Contents of the invention [0003] The technic...
