Technical field
The utility model is related to sensor technical fields, and in particular to a kind of abs sensor.
Background technology
ABS, that is, anti-lock braking system, full name are Anti-lock Braking System, can be mounted on any band hydraulic pressure
On the automobile of brake.In braking, the speed signal that ABS is transmitted according to each vehicle-wheel speed sensor can judge rapidly vehicle
The locking state of wheel closes the normally opened input solenoid valve started above locking wheel, makes brake force constant, if wheel continues to embrace
Extremely, then open normally closed output solenoid valve, the brake pressure on this wheel due to there is the pipeline of straight forward system hydrodynamic oil tank and
It moves down rapidly, it is therefore prevented that by the complete locking of wheel due to brake force is excessive.
Currently, existing abs sensor, includes sensing head assembly, plug-assembly, the sensing head assembly and plug
Component is connected through electric wire, wherein sensing head assembly includes sensing head shell, the Hall pipe, the magnetic that are arranged in sensing head shell
Iron, circuit board, circuit board are fixed on through fixing glue in sensing head shell, and plug-assembly includes plug body, is arranged in plug
Contact pin, contact pin locating piece in shell, still, the abs sensor of this structure, circuit board and sensing can be made for a long time by using
Fixation gumminess between head shell reduces so that circuit board fix it is not firm, in addition, vehicle jolts pair because of pavement behavior
The connection of abs sensor internal element impacts, and the working performance in turn resulting in abs sensor is unstable.
