Abstract

The invention relates to a driving system for a railway vehicle and the railway vehicle. The driving system comprises a plurality of sub driving systems, wherein each of the sub driving systems comprises a single wheelset, a brake caliper, a brake disc, an axle box, a gearbox, a driving mechanism and a gearbox grounding device; the axle box is mounted on the inner side of a wheel in the single wheelset; the brake disc is fastened on an axle of the single wheelset, and the brake caliper is mounted on an end cover on one side of the axle box for clamping the brake disc when the railway vehicle brakes; the gearbox is mounted on the axle of the single wheelset and is connected to the output end of the driving mechanism through an input shaft thereof; and the gearbox grounding device is mounted on the end cover of the gearbox. The driving system is used for overcoming the defect that the driving mechanism for the railway vehicle in the prior art is narrow in variable driving range, weak in driving force and short in service life, and expanding the variable driving range of the driving mechanism, improving the driving force and prolonging the service life.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a drive system for rail vehicles. Background technique [0002] Traditionally, the driving mechanism (for example, the drive motor) of the rail vehicle as a whole provides driving force for the axles of each wheel pair, thereby driving the rail vehicle forward. For example, when high power is required, the driving power of the driving mechanism is increased, so that each wheel For acceleration, the driving force of a drive mechanism is limited, resulting in a narrow variable drive range when the drive mechanism drives each wheel pair, and the long-term wear and tear of the drive mechanism results in a short service life. In fact, there are multiple working conditions in rail vehicles that require different power to drive each wheel set forward. It is difficult for the existing drive mechanism to provide different driving forces for each wheel set according to di...
