Abstract

The invention provides a box body of a gearbox for a rail transit vehicle. The box body comprises an output-end oil collection groove, an input-end oil collection groove, a middle-position oil collection groove and an oil tank, wherein the output-end oil collection groove and the input-end oil collection groove are formed in the upper part of the inner wall of the box body, and the middle-positionoil collection groove is located below the input-end oil collection groove, and located between an output-end bearing installation position and an input-end bearing installation position; output-endoil inlet holes are formed in the bottom of the output-end oil collection groove and the first sidewall of the middle-position oil collection groove, and used for lubricating an output-end bearing; the input-end oil collection groove is inclined downwards, input-end oil inlet holes are formed in the lower part of the sidewall of the input-end oil collection groove and the second sidewall of the middle-position oil collection groove, and used for lubricating an input-end bearing, and the second sidewall and the first sidewall are oppositely arranged; and the oil tank is arranged at the bottom of the box body. The box body provided by the invention can meet the working condition requirement during the high-speed running of multiple unit trains.

Description

technical field [0001] The invention relates to the technical field of rail vehicle transmission systems, in particular to a box body of a gear box of a rail vehicle. Background technique [0002] The gearbox of the rail transit vehicle is located at the lower part of the car body, suspended on the axle of the motor car, and directly bears the impact of the rail on the wheel set, and the working conditions are very harsh. [0003] The current rail transit gearboxes are mostly suitable for EMU trains with a speed of 250 kilometers per hour and below. For high-speed EMU trains with a speed of 350 kilometers per hour, the structural strength and lubrication system of the box in the prior art cannot meet the requirements of high-speed operation. Condition requirements. Therefore, it is necessary to propose a gearbox casing that can meet the working condition requirements of the high-speed operation of the EMU train. Contents of the invention [0004] The invention provides a...
