Abstract

The invention relates to the technical field of rack rail vehicle driving and braking, and provides a brake wheel pair for a non-power rack rail bogie and the non-power rack rail bogie, and the brake wheel pair comprises a wheel pair and rack rail wheels installed on the wheel pair; the toothed rail wheel is rotatably connected with the wheel pair through a rolling bearing; the rolling bearing comprises an inner ring and an outer ring which can rotate relatively, the outer ring is sleeved with the toothed rail wheel, and the inner ring is fixedly connected with the axle; at least one side of the toothed rail wheel is provided with a brake assembly, and the brake assembly is installed on the outer ring and used for limiting rotation of the toothed rail wheel. According to the brake wheel set, the toothed rail wheels matched with the toothed rail railway are arranged on the wheel set, braking force directly acts on the toothed rail wheels connected with the wheel set on the downhill road section with the large gradient, the traveling wheels cannot continue to move forwards, inertial impact caused by insufficient braking force is avoided, and the safety of a toothed rail vehicle is improved; the brake wheel pair is compact in structure and more flexible in layout.

Description

technical field [0001] The invention relates to the driving and braking technical field of rack cars, in particular to a brake wheel set for a non-power rack truck and a non-power rack truck. Background technique [0002] The cog railway is to add a steel rail with "tooth" in the middle of the ordinary railway. Through the meshing of the cog wheel of the bogie equipped on the cog car and the rack on the line, the traction and control of the cog car are realized. verb: move. [0003] The existing rack cars generally include a power bogie with a driving device and a non-power bogie without a driving device. Since the non-powered bogie has no power and is only equipped with driven wheelsets, on some downhill roads with relatively large slopes, only adhesive braking cannot provide sufficient braking force, thereby affecting driving safety. Contents of the invention [0004] The object of the present invention is to provide a brake wheel set for a non-power rack bogie and a n...
