Problems solved by technology

The overturning moment will lead to the unevenness of the vehicle wheels, and then affect the derailment coefficient, wheel load reduction rate, overturning coefficient and other indicators when the vehicle is running, and will have a certain impact on the safety of the vehicle, especially when the vehicle is running on a curve. situation, which has a greater impact on vehicle operation safety

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] like figure 1 As shown, a rail vehicle provided by the present invention is a low-floor rail vehicle such as an intercity vehicle, and the bogie installed on the rail vehicle adopts the form of independent wheels. The bogie includes frame 1, secondary suspension 2, primary suspension 3, axle bridge 4, wheels 5, driving and braking system and other components.

[0035] Among them, the frame 1 includes two side beams 6, two cross beams 7 and two longitudinal beams 8, and the centers of the two side beams 6 respectively protrude a cantilever beam 9, and the driving and braking system is suspended by a suspension device 10. on the outside of side beam 6. Two beams 7 are installed on the bottom of side beams 6, the two ends of beams 7 are fixed by welding the bottom of connecting beams and side beams 6, two longitudinal beams 8 are welded be...

Abstract

The invention relates to a rail vehicle anti-overturning method, a driving brake system and a rail vehicle, both sides of a frame are respectively provided with motor transmission mechanisms and basicbraking devices, the motor transmission mechanism comprises traction motors and gear boxes longitudinally coupled, and the motor shafts of the traction motors on both sides of the frame rotate in theopposite direction or reverse direction when a vehicle runs. The basic braking devices control the motor shafts to brake, and the directions of forces which are applied to the frame by the basic brake devices on both sides of the frame when the vehicle bakes during the vehicle running process are controlled to be same. When the vehicle bakes during the vehicle running process, the directions of braking forces generated at the gear boxes on both sides of the frame are same, an overturning moment applied to the frame can be avoided during braking, vehicle overturning can be effectively avoidedduring braking, and the vehicle operation security is improved.

Description

technical field [0001] The invention relates to a rail vehicle, in particular to a rail vehicle anti-overturning method and a driving braking system, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] In order to reduce the floor height of the bogies of urban rail transit low-floor vehicles, the driving and braking systems generally adopt a longitudinal coupling installation scheme. The driving and braking system includes two groups of motor transmission mechanisms, which are respectively hung and installed on the outer sides of the two side beams of the bogie frame. For example, a low-floor rail vehicle bogie disclosed in Patent No. 201510023470.8. [0003] Wherein, each group of motor transmission mechanism is composed of a traction motor and two gearboxes, the output ends on both sides of the traction motor are respectively connected to a gearbox, and the traction motor simultaneously drives the two gearboxes on the same side ...
