Abstract

The invention relates to a distributed driving new wheel-rail high-speed train system in the technical field of rail transit, comprising a plurality of bogie bodies and a pair of rail assemblies, wherein each rail assembly comprises a load bearing rail and a guide rail; each bogie body comprises a compartment connecting frame, a load bearing frame, load bearing wheels, guide wheels, a transverse telescopic linkage mechanism, a spring damping assembly, a shock absorbing assembly, and a motor mounting frame; the load-bearing wheels of each bogie body are two and roll on two load bearing rails respectively; the guide wheels of each bogie body are provided with two groups and roll on two guide rails respectively; each load-bearing wheel is provided with a power unit including a load-bearing wheel drive motor mounted on a motor mounting bracket; and the output spindle of the load-bearing wheel drive motor is drivingly connected to the wheel axle of the load-bearing wheel. Therefore, the distributed driving new wheel-rail high-speed train system enables each load-bearing wheel to be equipped with an independent power source.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a new wheel-rail high-speed train system. Background technique [0002] Wheel-rail trains and maglev trains are two main technical forms of rail transit. Among them, the wheel-rail train adopts the mode of meshing wheels on the track, and the wheels are in direct contact with the track. It is widely used in some special occasions such as railways, urban traffic, and mines. It has the advantages of reliability, strong transportation capacity, punctuality and speed, and high comfort. [0003] The limitations of traditional wheel-rail trains are mainly reflected in two points: (1) The load-bearing and guiding functions of the system composed of wheels and rails (referred to as wheel-rail system) are coupled. When the speed reaches above 400km / h, the dynamic performance of the wheel-rail contact drops sharply. At the same time, maintaining a high speed places strict requiremen...
