However, a driving mode is proposed in the rack car driving device disclosed in Chinese patent CN105460024A. The train using the device relies on the clutch as the power mode switching means, but there is a full range of rack gears idling, which causes unnecessary energy loss and improves the efficiency. The cost of using the train

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] refer to figure 1 and figure 2 , a train of the present invention that can realize multi-stage rack-wheel-rail power switching, including the front carriage 10, the middle carriage 11 and the rear carriage 12 that are pulled in a row in sequence, the front carriage 10, the middle carriage 11 and the rear carriage 12 Both are equipped with a front bogie 21 and a rear bogie 22 . The front bogie 21 of the front car 10 and the rear car 12 is a power type bogie, or the front bogie 21 and the rear bogie 22 of the front car 10 and the rear car 12 are all power type bogies. The power bogie is equipped with a power unit, a transmission system that provides power for the train to run, and a power switching device 30 that switches the transmission system between three states: neutral, rack drive, and wheel-rail drive. That is, there are two power config...

The invention relates to a train capable of realizing multi-stage toothed rail-wheel rail power switching. The train can meet the needs of different gradients for the power of a toothed rail-wheel rail train in the most reasonable way, and effectively utilize the power and existing equipment to reduce the operation and maintenance costs, and improve the utilization rate of the equipment at the same time. The train comprises a front carriage, a middle carriage and a rear carriage which are connected and hooked into a row in sequence, wherein the front carriage, the middle carriage and the rearcarriage are provided with a front bogie and rear bogie respectively. The front bogies of the front carriage and the rear carriage are power bogies, or the front bogies and the rear bogies of the front carriage and the rear carriage are power bogies; and the power bogie is provided with a power unit and a transmission system which provide power for train operation, and a power switching device which enables the transmission system to switch between three states of neutral position, toothed rail drive and wheel rail drive.
Description
technical field [0001] The invention relates to rail transportation, in particular to a train capable of realizing multi-stage rack-wheel-rail power switching. Background technique [0002] The rack car that existing mountain-climbing railway adopts has following several types: [0003] Single rack shape, running the whole line adopts gear-rack meshing as the driving scheme of the train. This driving scheme can ensure that the train has good climbing performance, but there are problems of high cost and difficult maintenance; [0004] Single wheel-rail shape, that is, the traditional steel wheel rail model, the adhesion of the steel wheel is used as the driving force of the train throughout the whole process. The drive scheme is very mature, most of the series parts are standardized, and the cost is low, but the train's climbing ability is weak; [0005] The rack-wheel-rail configuration, that is, the gear-rail meshing and the traditional wheel-rail mode are alternately us...
