Problems solved by technology

Since it must be installed at the end of the frame to ensure that the bolt connection will not fail, the safety margin of vibration intensity is sufficient, and the support cannot be designed too heavy, so the stiffness will be relatively low, and the first-order modal frequency of the support will also be low, which is easy to communicate with The main frequency of vibration on the line coincides or approaches, resulting in resonance or resonance, which reduces the safety of rail vehicles

Embodiment Construction

[0016] refer to figure 1 , figure 2 , the specific embodiment of the present invention includes the mounting end and the cantilever 6, one side 2 of the mounting end is the connecting surface of the axle box end, and the opposite side 8 is the mounting surface of the travel switch, and the above mounting surface of the travel switch is a toothed connecting surface 9, Since the weight of the brake travel switch is close to 10KG, under the condition of line vibration, it will have a greater impact on the bolt connection. Since there are only two bolts installed at the end of the axle box, in order to ensure sufficient connection reliability, the tooth surface and the tooth surface are used to ensure sufficient connection reliability. The friction between the surfaces ensures a firm and stable installation. The lower part of the cantilever is processed with a longitudinally inward 30-degree slope 10 relative to the tooth-shaped connecting surface 9 as the installation surface f...

Abstract

The invention provides a novel mounting bracket of a pilot and brake travel switch. The novel mounting bracket of the pilot and brake travel switch is characterized by comprising a mounting end and acantilever, wherein one side face of the mounting end is a shaft box end connecting face, the opposite other side face of the mounting end is a travel switch mounting face, and the lower portion, relative to the travel switch mounting face, of the cantilever is provided with a longitudinally inward oblique plane as a pilot mounting face. The novel mounting bracket of the pilot and brake travel switch has the advantages that by designing that the mounting end is connected to the end of a shaft box instead of the end of a non-framework, the weight is lighter; the lower portion, relative to the travel switch mounting face, of the cantilever is provided with the longitudinal oblique plane as the pilot mounting face so that obstacles can be smoothly removed from a track, and the stress caused by the obstacles from different directions can also be resisted; reinforcing ribs in the mounting end and a slab connected to the bottom of the shaft box end connecting face improve the integral rigidity; the upper edge of the shaft box end connecting face bends outwards, continuous operation can also be ensured under the situation of bolt failure, and the reliability is high; the structure adoptsintegral casting and does not welding, and the manufacturability is good.

Description

technical field [0001] The invention relates to a mounting bracket, in particular to a mounting bracket for a rail vehicle obstacle remover and a brake travel switch. Background technique [0002] In addition to the basic functions of bearing, vibration reduction and running, the bogie also needs to have some other auxiliary functions, such as obstacle removal, sand spreading, and tread cleaning. Therefore, on the premise that the bogie does not undergo major changes, to meet the above functional requirements, it is generally necessary to bolt a special bracket on the frame or axle box. [0003] At present, the bracket on the bogie with the function of removing obstacles and controlling the brake travel switch is installed at the end of the axle box or the obstacle remover is installed separately from the brake travel switch, and is welded with steel plates. In order to ensure that lower obstacles are removed, The brackets are generally longer. Since it must be installed a...
