Electric double-type brake signal transmitter

Abstract

An electric double-type brake signal transmitter comprises an upper valve body, a lower valve body, sealing assemblies and an electronic device assembly, wherein a flange seat is arranged at the top of the upper valve body, and an ejector rod is arranged on the flange seat. The sealing assemblies are arranged in the upper valve body and the lower valve body; a moving component is arranged on one side of the flange seat and moves synchronously with the ejector rod. The electronic device assembly comprises a circuit board cover, an electric switch, a travel sensor, a circuit board and a socket,the electric switch is used for sending out the travel sensor for recording the travel of the moving component, and the electric switch or the travel sensor is connected with the electronic and / or electromechanical measuring unit. In the transmitter, the electronic measuring unit is designed as an electronically controlled brake system measuring unit and is arranged in a partially closed circuit board cover, and the electronic shell is exchangeably connected to the receiving device; and the device is simple, easy to produce, high in reliability and low in cost.

Description

technical field [0001] The invention relates to the technical field of automobile braking control, in particular to an electrical dual-type braking signal transmitter, which is applied to vehicles with EBS braking systems. [0002] The invention relates to an electric dual-type brake signal transmitter, especially an electro-pneumatic double-circuit brake signal transmitter in a compressed air brake system of a vehicle, which is used to adjust the brake signal in the first brake circuit and the second brake circuit. brake pressure corresponding to the desired braking action, an electrical dual-type brake signal transmitter with a pedal-operated first valve system and a pneumatically actuatable and / or a second valve system mechanically operated by the first valve system, wherein the plunger of the first valve system pushes an electric switch for registering the start of operation of the regulating valve and / or for sending out an electric switch for registering the plunger A st...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the invention is to propose an electric dual-type brake signal transmitter, which solves the problem of the large size of the three-speed switch foot brake valve, inconvenient installation, large pedal force, and three micro-switches. Difficult signal adjustment, poor driving comfort, and no pressure limiting function, resulting in limited air pressure increase in the vehicle system; remove the air pressure acquisition module, improve data acquisition methods, and optimize the sealing structure; make the device simple and easy to produce Improve reliability and reduce costs
