Abstract

The utility model discloses an actuating mechanism electromagnetic valve of an automobile electronic control system, relates to an engine oil control valve of a variable valve timing system for a motor. The engine oil control valve is reliable in performance and a magnetic core of the engine oil control valve can be supported well. A support device of the engine oil control valve is simple in structure, and after being assembled, the magnetic core moves flexibly. The technical scheme includes that guide bearings are pressed to fit in a front yoke sleeve and a rear yoke sleeve for supporting the magnetic core, so that during operation of the engine oil control valve, the magnetic core can move flexibly and a purpose of fine control is achieved. The actuating mechanism electromagnetic valve of the automobile electronic control system is mainly applied to the machine oil control valve of the variable valve timing system for the motor, so that the magnetic core in the machine oil control valve moves flexibly and is reliable in performance.

Description

Automobile electric control system actuator solenoid valve

Technical field

The utility model relates to a kind of automobile electric control system actuator solenoid valve, particularly relates to a kind of OCV Oil Control Valve that is used for variable valve timing system of engine.

Background technique

VVT wide model on the new automobile motor is used, and it can promote engine power, moment of torsion, reduces oil consumption and exhaust emissions.OCV Oil Control Valve is the vitals in the VVT, and the control signal that it sends according to engine control system is switched towards the oil passageway of cam phaser and controlled oil flow rate, thereby reaches the purpose of accurate control cam phaser corner.OCV Oil Control Valve is a kind of Proportional valve of precision; Never allow to take place stuck phenomenon in the working procedure,, will cause a whole set of VVT to lose function as stuck phenomenon takes place; Use OCV Oil Control Valve for existing variable valve lift system; Commonly adopt mode that guide sleeve supports core axis and adopt sliding sleeve directly to support the mode of magnetic core, its shortcoming mainly is that the machining accuracy of such structural requirement part is high, and the flexibility of magnetic core is difficult to guarantee.

The model utility content

The purpose of the utility model is the deficiency to above-mentioned existing technology; Provide a kind of guide bearing that utilizes of reliable performance to support the automobile electric control system actuator solenoid valve of core axis; This supporting structure is simple, and the magnetic core motion of assembling back is difficult for taking place catching phenomenon flexibly.

The purpose of the utility model realizes through following technical proposals:

A kind of automobile electric control system actuator solenoid valve comprises valve pocket, and valve pocket endoporus front end is installed collar, spring seat, spring, spool successively to the rear end; The ear end face of valve pocket is connected fixing with preceding yoke cover front-end face; The front-end face of preceding yoke cover ear end face and o is connected fixing, and the ear end face of o is connected with back yoke cover front-end face to be fixed, and is equipped with support device in the endoporus of preceding yoke cover and back yoke cover; O is surrounded by valve shell outward; Magnetic core and core axis are installed in the o, and the core axis two ends stretch into respectively in the forward and backward yoke cover endoporus and supported by support device, and the front-end face of core axis contacts with the ear end face of spool; And make spring that certain decrement arranged; Magnetic core can be in o move left and right, said support device is a guide bearing, on the steel ball of the guide bearing before the core axis two ends are supported on respectively in yoke cover and the back yoke cover endoporus.

As preferably, between the front-end face of the ear end face of valve pocket and preceding yoke cover, between the ear end face of preceding yoke cover and the front-end face of o, and between the front-end face of the ear end face of o and back yoke cover the O RunddichtringO is installed all and seals.

As preferably, preceding yoke cover, back yoke cover are all and be interference fit between the guide bearing.

As preferably, be interference fit between core axis and the magnetic core endoporus.

The beneficial effect of the utility model is: simple in structure, requirement on machining accuracy is not high, adopts guide bearing to support core axis, the motion that makes the OCV Oil Control Valve inner magnetic core flexibly, reliable performance, avoided catching phenomenon.

Embodiment

Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.

To shown in Figure 6, a kind of automobile electric control system actuator solenoid valve comprises valve pocket 1 like Fig. 1; The endoporus front end car of valve pocket 1 has the jump ring groove, is contained in jump ring groove position in order to the collar 2 of axial limiting, from the solenoid valve front end to the rear end; Collar 2, spring seat 3, spring 4, spool 5 are installed in valve pocket 1 endoporus successively, and the ear end face of valve pocket 1 and preceding yoke overlap 7 front-end faces and are connected fixingly, and O RunddichtringO 6 is installed between the two; Before the ear end face of yoke cover 7 with the front-end face contact of o 8, seal with O RunddichtringO 6 between the two, the ear end face of o 8 connects with the front-end face of back yoke cover 9 to be fixed; O RunddichtringO 6 is installed between the two to be sealed; The outside of o 8 is surrounded by valve shell 13, adopts interference fit that guide bearing 12 is installed respectively in the endoporus of preceding yoke cover 7 and back yoke cover 9, and magnetic core 10 is installed in the o 8 with core axis 11; Core axis 11 adopts the mode of interference fit to be pressed in magnetic core 10 endoporus; Core axis 11 two end supports are overlapped on the guide bearing steel ball 15 in 9 endoporus at preceding yoke cover 7 and back yoke, and the front-end face of core axis 11 contacts with the ear end face of spool 5, and makes spring 4 that certain decrement arranged; Magnetic core 10 can move forward and backward under the double action of electromagnetic force and spring 4, and drive core axis 11 moves forward and backward.

Core axis 11 is the some contact with 15 ways of contact of guide bearing steel ball; And guide bearing steel ball 15 can move on guide bearing skeleton 14 under free state flexibly, clamping stagnation not, therefore; Support magnetic core 10 with guide bearing 12 and make that the motion of magnetic core 10 is more flexible, avoid catching phenomenon.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
