Abstract

The invention discloses a railway travelling device powerful in braking. The railway travelling device powerful in braking comprises a frame, wheels, axles and brakes, wherein the wheels are arranged at the bottom of the frame through the axles, each brake is arranged on the inner side of the corresponding wheel, a brake drum is arranged on the outermost side of each brake, a plurality of brake shoes are arranged on the inner side of each brake drum, a brake bar is inserted into a protruding portion of one brake shoe of each wheel, and a brake cylinder is connected to the other end of each brake bar. According to the railway travelling device powerful in braking, due to the facts that the shoe brakes are adopted, the brake bars are pushed through the brake cylinders, and the brake bars push the protruding portions on the brake shoes, the brake shoes have the tendency of outward expansion, and the brake drums arranged outside the brake shoes are extruded, and the braking effect is achieved; due to the fact that multiple brake shoes can be arranged, the braking effect can be enhanced, and the railway travelling device powerful in braking is simple in structure and novel in design, and is a novel railway travelling device.

Description

technical field [0001] The invention relates to a powerful braking railway driving device. Background technique [0002] Existing railway vehicles have heavy loads. Therefore, at high speeds, railway vehicles have a large forward inertia. It is very difficult to brake and stop in an emergency. When the parking position can be predicted, It is possible to decelerate in advance and let the rear stop, but this will prolong the parking time and cause a waste of operating time. In case of emergency, if the brakes cannot be stopped in time, it is easy for the vehicle to slide off the track together, causing certain damage. Loss, so a high-quality railway brake is very important for the operation of railway vehicles. [0003] Due to the late start, weak technical foundation and limited capital investment, my country's brake products are mainly low-end products. A few leading companies in the industry insist on independent innovation, increase investment in research and development...
