Embodiment Construction

[0051] The present invention will be further described below in conjunction with the drawings and embodiments.

[0052] Such as figure 1 As shown, the 200km / h high-speed freight car bogie of the present invention adopts a frame type bogie structure, which includes two wheel sets 1, a frame 2, four primary vertical hydraulic shock absorbers 3, and four primary axles. Box spring suspension system 4, four basic braking devices 5, two secondary rubber springs 6, two secondary transverse shock absorbers 7, two secondary vertical shock absorbers 8, two anti-snake damping Device 9, two anti-skid devices 10, one weighing valve 11, one longitudinal traction rod 12, four elastic safety chains 13, two secondary vertical stops 14, two secondary horizontal stops 15. The axle 16 adopts a hollow structure, such as figure 2 Shown. The wheels adopt straight web wheels 17, such as image 3 Shown.

[0053] The frame 2 is connected to the wheel set 1 through a axle box spring suspension system 4. ...

Abstract

The invention discloses a bogie for a high-speed rail wagon. The bogie comprises a framework, wherein two transverse ends of the framework are connected with a wheel set through two single-stage suspension systems respectively; a double-stage suspension system and a foundation brake device are arranged on the framework; and the front side and the rear side of the framework are provided with an anti-snakelike damper respectively. By the bogie, two-grade requirements that the shaft weight is 16.5t when the speed of the wagon is 200km/h as well as the shaft weight is 18t when the speed of the wagon is 160km/h can be met simultaneously; and the bogie has the remarkable characteristics of simple structure, high popularity and reliable performance.

Description

Technical field [0001] The invention relates to a railway freight car bogie, in particular to a high-speed railway freight car bogie. Background technique [0002] At present, railway freight car bogies generally have three-piece freight car bogies and framed freight car bogies. Due to the obvious shortcomings of three-piece freight car bogies, such as low diamond resistance, large unsprung mass, and inability to install disc brakes, The running speed will not exceed 120km / h, and the frame type freight car bogie has significant advantages such as high diamond resistance and low unsprung mass, and its overall dynamic performance is significantly better than the three-piece freight car bogie. According to the different configuration of frame bogies, there are generally two speed classes 120km / h and 160km / h. The domestic Zhuan K3 bogies belong to the 120km / h speed class bogies, and their typical characteristics are The suspension is a series of axle box suspension, and the basic br...
