The technical scheme is characterized by comprising a shell, wherein a stop iron is arranged in the shell, a sliding hole is formed in the middle of the stop iron, and an armature push rod is arranged in the sliding hole; the side wall of the armature push rod is provided with a step ring groove, so that the side wall of the armature push rod is dumbbell-shaped. The utility model discloses simplify the electromagnetism head structure, all integrated as a ladder core part traditional armature, case push rod and terminal shoe, armature push rod promptly to can reduce part quantity. The armature push rod is made of the same material as the armature, plays the role of the armature and can directly move, a complex magnetic reversing path is not needed any more, and the assembly requirement is greatly reduced.
Description
Technical Field
The utility model relates to a car variable speed hydraulic pressure solenoid valve field, more specifically says, it relates to an electromagnetic head structure integrates.
Background
The automatic gearbox is used to replace manual gearbox, especially in middle and high grade automobile. The electronic control system of modern vehicle engine is more and more inclined to select the electromagnetic valve as the actuator because the electromagnetic valve can directly control the fuel injection quantity and fuel injection timing, and part of fuel injection rate can also be realized by the electromagnetic valve, thus, three control items can be completed by only one actuator, and the hardware of the whole electronic system can be greatly simplified, therefore, the electromagnetic valve is one of the most important parts in the present automatic gearbox.
The prior Chinese patent with the publication number of CN103050217B discloses a proportional electromagnet for an electromagnetic valve of an automatic transmission, which comprises a sliding bearing, a stop iron, a push rod, a gasket, a coil component, an armature, a pole shoe, a yoke and a bearing seat, wherein the push rod and the armature are in clearance fit and are connected into a whole by riveting, and the push rod penetrates through inner holes of the sliding bearing, the stop iron, the gasket and the armature.
However, the solenoid valve has a complex structure, many parts, needs to maintain good coaxiality and matching, has high assembly requirements, needs to be realized by different process methods for the armature, the ejector rod and the pole shoe, has high cost, and needs to maintain the reverse magnetic path by using complex part shapes.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide an electromagnetic head structure integrates, it can reduce part quantity, no longer need complicated magnetic reversing path, requires greatly reduced to the assembly.
In order to achieve the above purpose, the utility model provides a following technical scheme:
an integrated electromagnetic head structure comprises a shell, wherein a stop iron is arranged in the shell, a sliding hole is formed in the middle of the stop iron, and an armature push rod is arranged in the sliding hole; the side wall of the armature push rod is provided with a step ring groove, so that the side wall of the armature push rod is dumbbell-shaped.
Furthermore, two yielding ring grooves which are respectively opposite to the end part of the armature push rod are formed in the inner wall of the sliding hole.
Further, the width of the end part of the armature push rod, namely the part with the larger outer diameter, is larger than that of the abdicating ring groove.
To sum up, the utility model discloses following beneficial effect has:
1. the traditional armature, a valve core push rod and a pole shoe are integrated into an armature push rod, so that the number of parts can be reduced, and the production cost is reduced;
2. an armature push rod is adopted, a complex magnetic reversing path is not needed, and the assembly requirement is greatly reduced;
3. the armature push rod adopts a stepped design and is dumbbell-shaped, so that the function of an anchor can be achieved, a magnetic path is optimized, and a limiting function is achieved.

Example (b):
an integrated electromagnetic head structure, refer to fig. 1, which comprises a shell 5, wherein a stop iron 1 is arranged in the shell 5, a sliding hole 11 is arranged in the middle of the stop iron 1 in a penetrating manner, and an armature push rod 2 is arranged in the sliding hole 11; in the embodiment, the whole stop iron 1 is T-shaped or straight-barrel-shaped; an end cover 6 is sleeved on the stop iron 1, so that one end of the sliding hole 11 can be closed; a coil 4 is arranged between the shell 5 and the stop iron 1, the coil 4 generates electromagnetic force after being electrified, so that the armature push rod 2 can be controlled to move, and the armature push rod 2 pushes a valve core 3 in the electromagnetic valve to move after moving, so that the electromagnetic valve function is realized.
The middle of the side wall of the armature push rod 2 is provided with a step ring groove 21, so that the armature push rod 2 is integrally dumbbell-shaped, and therefore the function of an anchor can be achieved, a magnetic path is optimized, and a limiting effect is achieved.
Two yielding ring grooves 12 which are respectively opposite to the end parts of the armature push rods 2 are formed in the inner walls of the sliding holes 11, and the width of the end parts, namely the large outer diameter parts, of the armature push rods 2 is larger than that of the yielding ring grooves 12.
The working principle is as follows:
the utility model simplifies the structure of the electromagnetic head, integrates the traditional armature, the valve core push rod and the pole shoe into a ladder core part, namely the armature push rod 2, thereby reducing the number of parts; the armature push rod 2 is made of the same material as the armature, plays the role of the armature and can directly move, a complex magnetic reversing path is not needed any more, and the assembly requirement is greatly reduced.
