Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing bogie has a large dead weight and insufficient radial positioning function of the wheelset on the curve, and provides an inner frame type forced steering bogie and a railway vehicle, which reduces the dead weight by using the inner frame , the figure-eight displacement of the bogie wheel set on the curve is realized by using the forced guide mechanism

Embodiment 1

[0029] In one or more embodiments, an inboard frame forced guide truck is disclosed, see figure 1 and figure 2 , its structure includes: wheel set 1, axle box 3, primary suspension system 2, forced guiding mechanism 5, inner frame 4, elastic side bearing 6 and braking device 7.

[0030] Specifically, the structure of wheel set 1 refers to image 3 , including: wheels 11, axle shafts 12, brake discs 13 and bearings 14 are press-fitted. The wheels 11 are arranged at both ends of the axle shaft 12 , two bearings 14 are located inside the two wheels 11 , and a brake disc 13 is installed in the middle of the axle shaft 12 . The inner frame 4 is located between the two wheels 11 .

[0031] Primary suspension system 2 structure reference Figure 4 , including: spring group 21 and rubber stack 22. Two spring sets 21 are located on both sides of the rubber stack 22 . The primary suspension system 2 is located between the axle box 3 and the frame, and plays the role of buffering ...

Abstract

The invention discloses an inner side framework type forced steering bogie and a railway vehicle. The inner side framework type forced steering bogie comprises an inner side framework, forced guide mechanisms are arranged on the two sides of the inner side framework respectively, each forced guide mechanism comprises a guide base, a first pull rod and a second pull rod, the first pull rods and thesecond pull rods are connected with the guide bases respectively, and the far ends of the first pull rods and the far ends of the second pull rods are connected with axle boxes of front wheels and axle boxes of rear wheels respectively; each guide base is provided with a lever hole used for being connected with a vehicle body, and when the vehicle passes through a curve, the lever holes can drivethe forced guide mechanism to do arc motion through relative rotation generated by the vehicle body and the bogie, so that the radial positions of the front wheel pair and the rear wheel pair tend tobe changed. By the adoption of the inner side framework, the transverse span of the framework is reduced, and the mass of the framework is reduced; by adopting the wheel set with the single brake disc and the built-in bearing, the number of the brake discs is reduced, the length of the axle is shortened, and the mass of the wheel set is effectively reduced. Therefore, the mass of the whole bogieis effectively reduced.

Description

Technical field [0001] The invention relates to the technical field of railway vehicle bogies, and in particular to an inner frame forced steering bogie and a railway vehicle. Background technique [0002] With the development and progress of railway truck technology, the freight truck operating department has gradually increased its requirements for the operating performance and operating costs of freight trucks. Specifically, it requires freight trucks to reduce their own weight and not only have good operating performance in a straight line, but also have to Good running performance on curves and less wheel wear. [0003] The inventor found that most existing bogies use an outer frame, that is, a structure in which the side beams of the frame are placed outside the wheel. The outer frame is larger in size and heavier in weight, and almost all existing forced guide radial adjustment mechanisms are designed. Based on the outer frame bogie, its structure is relatively compl...
