Abstract
The utility model relates to an opening degree sensor main body of a non-contact type foot brake valve. The opening degree sensor main body is characterized by comprising structures for mounting double sensor components, and each structure comprises a shaft hole for mounting an oil-containing bearing, an annular groove for limiting the rotation of a pivot shaft, an annular rib for preventing assembly dislocation of the pivot shaft, an annular V-shaped groove for mounting a rubber O-shaped ring, and an L-shaped hook and a barb, which are used for fixing and compressing a PCB (printed circuit board) equipped with a magnetic sensitive element. The bearings, the pivot shafts, the PCBs equipped with the magnetic sensing elements and the like can be mounted on the sensor main body for constituting a sensor assembly, and the whole sensor assembly can be assembled on a valve body of the foot brake valve through the sensor body.
Description
Technical field
The utility model relates to a kind of main body of contactless jaw opening sensor, the main body of the contactless jaw opening sensor of highi degree of accuracy that especially a kind of foot brake valve is used.
Background technique
The electric brake system of vehicle and retarder BAS need the accurate aperture of measuring brake valve; Jaw opening sensor in the past all is based on the design of brush contact-cup anemometer; So-called brush contact-cup anemometer is meant the potentiometer that adopts swept resistance; Owing to adopt the feeler contact; So the electrical spark that have (rotational life: about 3,000,000 times) easy to wear, poor reliability, produces once in a while can disturb working state many shortcomings such as (thereby burying potential safety hazard) of ECU, under strong motion, high greasy dirt, high dust, extreme temperature and humidity environment, also there is the bad problem of environmental suitability simultaneously.Above-mentioned many shortcomings all can have a strong impact on the EBS electronic brake system accuracy of BAS work of unifying, and then influence vehicle driving safety.
The model utility content
In order to overcome the existing shortcoming that brush contact-type jaw opening sensor is easy to wear, precision is low, need a kind of foot brake valve with the contactless jaw opening sensor of highi degree of accuracy, this sensor utilizes Hall effect principle detection angles; To reach linearity height; The purpose of long service life, the utility model is the main body of this sensor, is used for the various assemblies of sensor installation; Guarantee each assembly correct assembling, make that sensor is correct, stable, the operation of long-life.
To achieve these goals, the utility model adopts following technological scheme:
The contactless jaw opening sensor main body of the utility model; Has the structure that the double-sensor assembly is installed; Each structure all comprises the axis hole that is used to install oil-impregnated bearing, has the circular groove spacing to pivoted, has the ring rib that prevents pivot assembling dislocation; Have the annular V-shaped groove that rubber o-ring is installed, have L type hook and the barb fixing and compress the pcb board that magnet-sensitive element is housed.Axis hole can be pressed into oil-impregnated bearing through the mode of interference fit, be used to support pivot and enable smooth-going rotation; Around axis hole, be distributing groove and rib of central sector with the axis hole axis; Change in the stopper posts embedded groove of joining on the pivot of back in completion; Groove has the effect of limit pivot angle; Rib prevents that then aforementioned stopper posts is inserted wrong position in assembly process, and assurance can only uniquely embed in the aforementioned grooves possibly; The annular V-shaped groove is used to locate rubber o-ring; L type hook and barb can have fixing and compress the function of the pcb board that magnet-sensitive element is housed, and compress the rubber o-ring that is installed between it and the annular V-shaped groove through compressing pcb board simultaneously, realize sealing and preventing the function that pcb board rotates; Overhead structure has the function that the pcb board of magnet-sensitive element is equipped with in quick assembling.
