Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 1 to Figure 5 As shown, the intercity EMU power bogie of the present invention includes a frame 1, two wheel-to-axle boxes 2, four primary suspension components 3, a secondary suspension component 4, a traction component 5, and two drive components. The device is composed of 7, four basic brake devices are composed of 6 and shaft end equipment 8.

[0018] Frame 1 is composed of two side beams, two transverse beams and two longitudinal beams, and the connection of the transverse beams adopts the structural form of adding a transition seat.

[0019] The gear box of the driving device composition 7 is fixedly connected at four points with a C-shaped bracket 6-1 and the gear box hanger 1-2 installed on the beam 1-1 of the frame 1. The safety margin is large and the coupling becomes variable under heavy vehicle conditions. The position is ...

Abstract

An intercity electric multiple unit (EMU) power bogie relates to the technical field of EMU bogies. The intercity EMU power bogie comprises a frame, two wheel set and axle box assemblies, four primary suspension assemblies, a secondary suspension assembly, a traction assembly, two driving device assemblies, four basic braking device assemblies, and shaft-end equipment. The gear box of the power bogie is suspended in a C-shaped bracket structure, which has the advantages of small coupling displacement and higher installation reliability compared with the hanger rod structure of the previous gear box. The bogie and the train body are connected by a connection sleeper beam, the train body and the bogie can be separated quickly and conveniently in application and maintenance, and modular design of the bogie is realized. The primary suspension devices are each provided with a primary stop pin, and the primary stop pins can support the train body and achieve a safety protection effect when steel springs are broken. The wheel set and axle box assemblies are provided with anti-off plates which can prevent an axle box swivel arm from falling off when axle box swivel arm installing bolts are loosened.

Description

technical field [0001] The invention relates to the technical field of train bogies, in particular to a power bogie for intercity trains. Background technique [0002] The design and structure of the power bogie of the existing intercity EMU is complex, and the main structure of the motor suspension and gearbox suspension cannot adapt to the characteristics of fast start and stop of the intercity EMU, large passenger capacity, etc., and most of the secondary suspension methods are 4-point control Due to the design principle, the interface between the bogie and the car body is complicated, and the separation of the car body and the bogie cannot be realized quickly and conveniently during the maintenance process. The suspension of the gearbox adopts the boom structure, and the installation with the bogie is unreliable. The primary suspension device of the existing bogie does not have a primary stop structure, and when the steel spring breaks, it is easy to cause a safety acci...
