Abstract

The invention discloses a rotating speed sensor, comprising a housing (1); a segment of external threads (11) are arranged on the outside of a left end of the housing (1); a left stepped hole (2), a middle stepped hole (3) and a right stepped hole (4) are axially arranged in the housing (1); an epoxy resin sleeve (21) is embedded in the left stepped hole (2); the epoxy resin sleeve (21) is internally provided with a Hall element (22) and a neodymium boron iron magnetic steel (23); the middle stepped hole (3) is internally provided with a printed circuit board combination (31), a sleeve (32) and a mounting sleeve (33); the right stepped hole (4) is also internally provided with an aviation plug (41). The rotating speed sensor is provided with the external threads, and the housing is internally provided with the epoxy resin sleeve, allowing a relevant circuit board to be arranged in a relatively sealed space; the housing is prepared by stainless steel materials, and possesses the functions of dust prevention and corrosion protection; the rotating speed sensor has a reasonable and compact structure, is convenient to assemble and disassemble, and can prolong the service life of a product.

Description

technical field [0001] The present invention relates to speed sensors for monitoring vehicle engine or wheel speed. Background technique [0002] At present, ordinary speed sensors used to monitor the engine speed or vehicle speed of various types of motor vehicles generally adopt mechanical sensing structures. Since most of the corresponding positions of motor vehicles are driven by gears, ordinary speed sensors are easily mixed with impurities and dust. It will increase the wear of related components and cause damage to the machine parts, which will not only damage the service life of the product, but also affect the speed measurement and the driver's judgment, which will cause disadvantages to driving safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotational speed sensor that is easy to install and can prevent dust and corrosion. [0004] Technical scheme of the present invention is as follows: ...
