Load sensor

Abstract

The invention relates to a load sensor. According to the design, the load sensor is used to continuously measure loads of a railway vehicle and convey an output pressure of air used for braking. The load sensor comprises a main body, wherein a cavity body at the center part comprises a disk on a diaphragm installed around peripheries of the main body; the upper part of the main body comprises a first orifice and a second orifice, rods touching the diaphragm are installed in the orifices, and the rods are loaded elastically so as to press against the diaphragm; a saddle valve which is loaded by a spring towards the rod is disposed on the wall part of the orifice above the rod and is used to seal the orifice and provide connection between the first orifice and the second orifice; the spring of the saddle valve is placed around a leg part of the valve and presses against a seat part of the valve; the opened cavity body which encloses a stopping block and is located on the lower part of the main body comprises movable and fixed annular limiting parts which stop separation from the cavity body; and end faces of the rods located on the contact side of the disk capable of elastic deformation, and end faces of a push part located on the contact side of the diaphragm are made into a flat shape.

Description

technical field [0001] The invention relates to the field of railway transportation engineering. In particular, consider the design of load cells, which are self-adjusting weighing devices used in rail transport. Background technique [0002] The load sensor is designed to continuously measure the load of the rail vehicle as a function of the mechanical action of that part of the vehicle load and to transmit the output pressure of the air used for braking. The load of the vehicle acts directly on the load sensor without an intermediate link. This provides accurate action, eliminates the need for servicing, and facilitates installation. Load cells have relatively low air consumption. [0003] The load cell can be used in the coil spring or leaf spring suspension system of the truck. There are two types of load transfer from the vehicle to the load sensor. Loads can be passed as follows: [0004] - In a sprung vehicle, the load sensor is located between the coil springs ...

This, in turn, also leads to the fact that pressure is transferred from the pusher to the diaphragm through the disc or plate at a point off the geometric center of the diaphragm rather than at the center
