Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] As shown in Figures 1 and 2, a four-axle high-speed bogie for locomotives of the present invention includes a frame 8 and four wheel pairs 1 mounted on the frame 8, and the wheel pairs 1 are installed on the frame 8 through a suspension mechanism. Above, each wheel pair 1 is respectively connected with the transmission mechanism and the driving device installed on the frame 8, and the four wheel pairs 1 are divided into two groups in pairs, and the two wheel pairs 1 in the same group are connected by spherical axle box bearing The equalizing beam 2 is connected, and the equalizing beam 2 is fixed on the frame 8 through the supporting shaft 24, and one or more coil springs 22 are arranged between the equalizing beam 2 and the frame 8. Each set of wheelsets 1 and the corresponding two equalizing beams 2 form a parallelogram mecha...

Abstract

The invention relates to a four-axis high speed turning frame used for s vehicle, which comprises a truss and four wheel sets, a driving device, a hanging mechanism, a brake device and a driving mechanism which are arranged on the truss, wherein, the wheel sets are arranged on the truss via the hanging mechanism, and each wheel set is respectively connected with the driving mechanism and the driving device which are arranged on the truss. The four wheel sets are divided into two groups in pairs, and two wheel sets in a same group are connected with each other via a balance beam of a bearing with a spherical surface axis box. The balance beam is fixed on the truss via a supporting shaft, and one or more than one screw spring is arranged between the balance beam and the truss. The four-axis high speed turning frame has big traction power, big adhesion weight, big traction capability, good curved line passing performance and small friction consumption of a wheel track.

Description

technical field [0001] The invention mainly relates to the field of bogies of railway locomotives, in particular to a four-axis high-speed bogie for locomotives, especially suitable for railway locomotives with a speed of 200km / h. Background technique [0002] In the existing technology, the bogie technology of 200km / h speed class electric locomotive is relatively mature in Europe, such as X2000, KTT, 1016, 101, S252, BB36000 and so on. Their power car bogie structures have their own characteristics, but they all adopt the design principles of high reliability, light weight, maintenance-free, replacement parts; they all adopt the motor full suspension structure to reduce the unsprung weight to meet the high-speed running performance A large number of experimental verification work has been carried out, and its safety and reliability have been verified by operation. [0003] For China, on the basis of summarizing quasi-high-speed locomotives such as SS8, SS9, and DF11, the c...
