Problems solved by technology

In addition, the arrangement of the brake lever of this basic brake device generally forms a certain angle with the longitudinal vertical plane of the vehicle, which will easily cause the wear of the joint between the fulcrum hole of the brake lever and the pin to deepen, and at the same time, the brake shoe may appear different degrees. Eccentric wear will adversely affect the driving safety of the vehicle

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 The suspended foundation brake device of the railway freight car bogie shown includes two brake beams in an equilateral triangular bracket structure 1, two pairs of brake levers 2, two brake beam booms 3, four Suspender 4, four brake shoe latches 5, four brake shoe holders 9, four brake shoes 6, a lower rod 7 and sixteen connecting round pins 8.

[0031] Such as Figure 6 The middle hole bushing 2.1 is pressed into the upper hole 2.2, the middle hole 2.4 and the lower hole 2.3 corresponding to the brake lever 2 in the form of interference fit; Figure 7 The middle round hole bushing 3.1 is pressed into the upper round hole 3.2 and the lower round hole 3.3 corresponding to the brake beam suspender 3 in the form of interference fit; Figure 8 The middle hole bushing 4.1 is pressed into the upper hole 4.2 and t...

Abstract

The invention relates to hanging type foundation brake rigging of bogie of a railway wagon. The hanging type foundation brake rigging of the bogie of the railway wagon comprises two brake beam components, two pairs of brake levers, four brake shoes and a lower pull rod. The two ends of the two brake beam components are hinged to four brake shoe holders in a symmetrical mode, the four brake shoes are fixedly mounted on the four brake shoe holders respectively, the four brake shoe holders are further hinged to the lower ends of four hanging rods respectively, and the upper ends of the four lifting rods are used for being hinged to break beam hanging arms on a swing bolster component. The first pair of braking levers and the articulated shaft of a supporting column are further hinged to the lower ends of a pair of brake beam hanging rods, and the upper ends of the pair of the break beam hanging rods are used for being hinged to two brake beam hanging rod supports on the swing bolster component. The hanging type foundation brake rigging is mounted and fixed on the swing bolster component of the bogie, and thus the unsprung mass of the bogie is reduced. Meanwhile, when vehicle brake is released, the foundation brake rigging only bears frictional resistance when a hinge pin part rotates, the frictional resistance is relatively small, and the improvement of performance of releasing of brake can be facilitated.

Description

technical field [0001] The invention relates to a railway freight car bogie, in particular to a suspension type foundation braking device for a railway freight car bogie. Background technique [0002] The foundation braking device of the bogie is the terminal output device of the braking force of the railway vehicle braking system. The braking force is finally transmitted to the brake shoe of the foundation braking device, causing the brake shoe to move in close contact with the wheel tread, causing a Slewing frictional resistance, so that the running railway vehicle brakes and decelerates until it stops. Whether the structure and performance of the foundation brake device is good or not is directly related to the driving safety of the railway vehicle. At present, domestic railway freight car bogies generally adopt the basic brake device with sliders at the end of the brake beam. This basic brake device is generally installed in the guide chute of the three-piece cast steel...
