Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is the band vacuum sensor servo-unit providing a kind of reasonable in design, structure simple, esy to use, safe and reliable.
For achieving the above object, the utility model provides following technical scheme: a kind of band vacuum sensor servo-unit, comprise front case, rear housing and diaphragm, the chamber that front case and rear housing surround is separated into ante-chamber and back cavity by described diaphragm, described ante-chamber upper end is connected with engine air inlet tube, back cavity lower end is provided with plasmas channel, described ante-chamber lower end is connected with vacuum sensor, this vacuum sensor comprises the sensor outer housing being packaged with integrated circuit, be arranged on the Connector Clip slot of sensor outer housing front end and be arranged on the screw nipple of sensor outer housing rear end, described screw nipple is socketed with retracing spring, power connection is provided with in described Connector Clip slot, ground joint and signal output connector, described sensor outer housing front end face integral middle is provided with insertion pipe, the through hole be in communication with the outside is offered in the middle part of described insertion pipe, described insertion pipe outside face is provided with the locating groove of annular.
By adopting technique scheme, when vacuum booster vacuum gave warning in advance lower than safety value (before affecting service brake safety) time, making chaufeur obtain information and taking suitable executing to arrange in advance, generation of preventing accident; Vacuum sensor vibrational power flow is reasonable, screw nipple is socketed with after retracing spring final vacuum degree sensor is connected with vacuum booster, retracing spring has an outside thrust, vacuum sensor is connected reliably with vacuum booster, not easily loosens; Insertion pipe structure is simple, easy to use.
The utility model is set to further: described front case lower end is provided with the tapped bore mated with described screw nipple, described vacuum sensor is threaded connection pipe and is threaded with tapped bore, and described retracing spring is compressed after screw nipple is threaded with tapped bore.By this setting, vacuum sensor is easy to connect, fixing reliable, not easily loosens.
The utility model is also set to further: described sensor outer housing outside face has been threaded hexagonal nut.By this setting, vibrational power flow is more reasonable, and after arranging hexagonal nut, assembly and disassembly operations is convenient.
The utility model is also set to further: described screw nipple front end and sensor outer housing rear end are welded and fixed.By this setting, screw nipple is fixing reliable.
The utility model is also set to further: described screw nipple is formed by stainless steel material manufacture.By this setting, screw nipple not easily gets rusty, reliable operation.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is more reasonable, when vacuum booster vacuum gave warning in advance lower than safety value (before affecting service brake safety) time, make chaufeur obtain information and take suitable executing to arrange in advance, generation of preventing accident; Vacuum sensor vibrational power flow is reasonable, screw nipple is socketed with after retracing spring final vacuum degree sensor is connected with vacuum booster, retracing spring has an outside thrust, vacuum sensor is connected reliably with vacuum booster, not easily loosens; Insertion pipe structure is simple, easy to use.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
