Embodiment Construction

[0011] The present invention will be further described below in conjunction with drawings and embodiments.

[0012] The whole adopts BOBO-BOBO axle type, that is, each locomotive has two bogies at the front and rear, and each bogie is composed of two BO bogies. to combine figure 1 and 2 The basic structure and specific embodiments of the invention can be seen. In the figure 1-steering frame; 2-car body; 3-intermediate frame; 4-driver seat; 5-single drawbar; 6-double drawbar. The fifth wheel 4 is fixed under the car body 2. The fifth wheel 4 has a set of single drawbars 5 and a set of double drawbars 6 respectively connected to the two bogie end beams 7 and 8 on the locomotive. The traction force is directly transmitted from the frame end beams. To the car body without going through the intermediate frame. There are three lugs 9, 10, 11 on the bottom surface of the structure of the traction seat 4, which are respectively connected with the traction rod through a ball joint,...

Abstract

The invention discloses an eight-shaft device for tracting a locomotive. The device adopts the BOBO-BOBO shaft mode, namely, each locomotive is provided with a front steering frame and a rear steering frame, wherein each steering frame comprises two BO type steering frames, a tracting seat is fixed under a locomotive body, and a group of single tracting rods and a group of double-traction rods are arranged on the tracting seat and are connected with the end beams of the two steering frames; and the tracting seat has the structure that the bottom surface is provided with three lifting lugs which are respectively connected with the tracting rods by globe joints, each single tracting rod is connected with the end beam of the leftwards rotatable steering frame, and the double-traction rods are connected with the end beam of the rightwards rotatable steering frame. The structure of the device has reasonable arrangement in the premise that the space of each steering frame is compact and simple; and the device does not generate movement interference, shaft load transfer is reduced when the dynamic performance of each steering frame is guaranteed, and the requirement of starting tractive force can be satisfied.

Description

Technical field [0001] The invention belongs to the field of railway locomotives, especially the manufacture of locomotive traction transmission mechanism devices. Background technique [0002] As the traction power of the locomotive increases, the eight-axle locomotive, as a traction method, can obtain higher traction capacity while avoiding double-locomotive reconnection. Advanced eight-axle locomotives generally adopt the BOBO-BOBO axle type, that is, each locomotive has two front and rear bogies, and each bogie is composed of two BO-type bogies. Eight-axle locomotives are widely used in Russia. So far, the ЭП100 passenger locomotive has a single-section power of 9600kw and a maximum speed of 200km / h. Due to the complex structure of the bogie, it is difficult to design a loading device that can meet the requirements of traction force transmission and vehicle dynamics. If the traditional traction device is used, it is difficult to meet the compact space requirements. C...
