Problems solved by technology

[0004] Obviously, the above-mentioned power bogie has a complex structure and is not suitable for use as a trailer bogie without power. Lower mass will greatly affect the dynamic performance of the vehicle
[0005] In addition, the existing cogwheel trailer bogies have no cogwheels, and on slopes with a slope greater than 60‰, only the adhesion of the wheels cannot provide sufficient braking force.

Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0027] Such as figure 1 As shown, the non-power bogie with rack brake of the present embodiment includes a rack wheel 3 and a rack wheel support beam 2 , a brake drum 1 , a brake band 6 , a frame 4 , and wheels 5 .

[0028] The rack wheel 3 is installed in the middle of the rack wheel support beam 2 through the rack wheel shaft, and a brake drum 1 is respectively installed on both sides of the rack wheel 3, and the rack wheel 3 and the brake drum 1 are c...

Abstract

The invention discloses a rack rail braking non-power bogie and a braking method thereof. The non-power bogie comprises a framework and wheels, a rack rail wheel supporting beam is installed on the framework, and rack rail wheels installed on rack rail wheel shafts are arranged in the middle of the rack rail wheel supporting beam; brake drums are mounted at one side or two sides of the toothed rail wheel, and the toothed rail wheel and the brake drums are coaxially arranged; the toothed rail wheel, the brake drum and the toothed rail wheel shaft are in interference connection; the rack rail wheel supporting beam, the rack rail wheel and the brake drum are all located in the upper portion of a primary spring of the bogie and located in the middle of the framework. A brake belt is arranged on the surface of the brake drum in a surrounding mode. The dynamic performance and the braking performance of the bogie are remarkably improved.

Description

technical field [0001] The invention relates to a rack brake non-power bogie and a braking method thereof, belonging to the field of non-power bogies. Background technique [0002] In the present rack car bogies, the rack wheels are mostly installed on the wheel axles, which can provide driving force for the vehicle through meshing transmission with the rack bars on the rack road section. For example, the Chinese invention patent application CN109532914A discloses a rack bogie with independently rotating wheels. The drive shafts are connected to the inner shaft boxes of the two groups, and the rack wheels are installed on the drive shafts. The wheel can be meshed with the gear rail and used as the driving wheel of the whole bogie; the wheel shaft is arranged on the inner shaft box, and the wheel is installed on the wheel shaft, and the wheel is in contact with the rail and rotates relative to it; The rail wheel rotates independently of the wheel, and the rotation of the whe...
