Problems solved by technology

[0002]Currently, most of the freight electric locomotives running on my country's lines adopt DC drive, such as SS1, SS3, SS4, SS6, SS7 DC drive electric locomotives, the existing DC The axle load of the Co bogie of the transmission freight electric locomotive is 23 tons, and the traction point is high, which limits the traction of the locomotive; the maximum speed is 100km / h, which limits the running speed of the locomotive on the line; the maximum power of the motor is 800kw, and the power of the locomotive is small , which limits the speed and cargo volume when the locomotive is pulling the vehicle; the suspension system of the first series is soft and the second series is hard, and the running stability of the locomotive is poor

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like figure 1 As shown, a locomotive high-adhesion heavy-duty freight Co bogie provided by the embodiment of the present invention includes three wheel pairs 5, and two sets of axle box devices 13, a set of drive unit 15, and a large wheel set are installed on each wheel pair. Power AC traction motor 16, they form the wheel pair driving device. Each axle box 13 is equipped with two primary springs 8, and the wheel set 5-1, 2 is equipped with a vertical primary vertical shock absorber 6. The frame 11 is installed on the primary spring 8, and the primary vertical vibration damper The device 6 connects the frame 11 and the axle box 13. Three secondary springs 10 are installed on each side of the frame 11. The car body 1 falls on the secondary springs 10. Each side of the bogie is equipped with a secondary vertical shock absorber ...

Abstract

The invention relates to a Co bogie for a heavy-load alternating-current transmission power freight locomotive on a railway, in particular to a Co bogie for a high-adherence heavy-load freight locomotive, comprising wheel pair driving systems, a framework, a two-series suspension device, a traction device, a motor suspension device and a braking device. Three wheel pair driving systems are installed on each bogie and adopt integrated axial suspension drives with flexible axle couplers and alternating-current traction motors; gear boxes are in load bearing structures; a first-axle wheel pair axle box device and a third-axle wheel pair axle box device are provided with integrated conical bearings with small axial clearances, and a second-axle wheel pair axle box device is provided with an integrated cylindrical bearing with a large axial clearance. The bogie structure provided in the invention can satisfy the adoption requirements of 25-ton axle-load electric locomotives.

Description

technical field [0001] The invention relates to a bogie of a railway heavy-duty freight AC drive electric locomotive, in particular to a high-adhesion heavy-duty freight locomotive Co bogie. Background technique [0002] At present, most of the freight electric locomotives running on my country's lines adopt DC drive, such as SS1, SS3, SS4, SS6, SS7 DC drive electric locomotives. The axle load of the Co bogie of the existing DC drive freight electric locomotive is 23 tons. The high point limits the traction of the locomotive; the maximum speed is 100km / h, which limits the running speed of the locomotive on the line; the maximum power of the motor is 800kw, and the power of the locomotive is small, which limits the speed and cargo volume when the locomotive pulls vehicles; If the suspension system is soft or hard, the running stability of the locomotive is relatively poor. [0003] The AC drive freight electric locomotive has just started in my country, and the mature and mass...
