TECHNICAL FIELD
[0001] The utility model relates to the technical field of stabilizer bar disconnecter, especially to a limiting sealing shell of stabilizer bar disconnecter. BACKGROUND
[0002] The transverse stabilizer bar, short for stabilizer bar, also known as anti-roll bar and balance bar, is an auxiliary elastic element in the automobile suspension and an indispensable mechanical structure for balancing the left and right sides of the automobile.
[0003] At present, the stabilizer bar of most four-wheel drive off-road vehicles is a split stabilizer bar. This split stabilizer bar is an indispensable auxiliary accessory for off-road vehicles to get out of trouble. When the vehicle is running on a bumpy road with the wheels suspended, the stabilizer bar can be controlled to separate the left and right sides, allowing the vehicle to have a larger lifting stroke and providing power to the vehicle. When the vehicle is on a paved and smooth road, in order to ensure the stability of the vehicle, the stabilizer bar needs to be controlled to be stable and connected as a whole on the left and right sides to ensure the stability of the vehicle when driving at high speed.
[0004] This stabilizer bar needs to be provided with a disconnecter in the middle. The stabilizer bar is also made into two sections.

The transmission structure inside the disconnecter connects the two sections of the stabilizer bar. This transmission mechanism needs to be disconnected and connected in the disconnecter shell. The sealing of the disconnecter shell needs to be ensured.
[0005] Some of these shells use electromagnetic coils to adsorb the transmission device. The electromagnetic coil needs to be installed stably. The electromagnetic coil can drive the transmission device to slide and disconnect, or generate a pushing force to connect the transmission of the two stabilizer bars. The electromagnetic coil is placed in the sealed cavity of the disconnecter shell with a certain gap.

[0037] Please refer to Figs. 1 to 4 The utility model provides a limit sealing shell body of stabilizer bar disconnecter, in order to better understand the above technical scheme, below will combine with the specific embodiment of the specification and the above technical scheme is explained in detail.
[0038] In the utility model technical scheme one specific embodiment:
[0039] Including left shell 1, right shell 2, pre -tightening column 3 and electromagnetic coil 4;
[0040] Left shell 1 and right shell 2 are both to left and right sides convex half shell shape structure, and left shell 1 and right shell 2 are mutually assembled as integral closed shell, and the center of left shell 1 and right shell 2 is all opened, and the opening of left shell 1 and right shell 2 is sealedly connected with stabilizer bar;
[0041] The rim of left shell 1 is provided with a plurality of locking holes 12, and the rim of right shell 2 is provided with a plurality of butting holes 22, each locking hole 12 is aligned with one butting hole 22, and each locking hole 12 and one butting hole 22 are locked by a bolt;
[0042] Left shell 1 and right shell 2 are locked by the bolt in locking hole 12 and butting hole 22.
[0043] The left side wall of left shell 1 is provided with slip column 11, and slip column 11 is a right convex circular tube;
[0044] When left shell 1 and right shell 2 are in stable splicing state, the axis of left shell 1 opening and right shell 2 opening coincides, the splicing surface of right shell 2 and left shell 1 is a flat surface, facilitating the subsequent application of adhesive, the splicing gap between left shell 1 and right shell 2 is on the same plane, and the splicing surface of left shell 1 and right shell 2 is also coated with adhesive.
[0045] When the adhesive is applied to the sealing end face of the shell, the line diameter of the adhesive is controlled to be 1.0-2.0 mm, and the adhesive track is reasonably planned to ensure that the adhesive is continuous and the sealing property is ensured.
[0046] It can also ensure that the splicing is more rigorous, and the installation and assembly method of the device can allow the splicing surface of the right shell 2 and the left shell 1 to have more errors, and if a sealing gasket commonly used in vehicle sealing assembly is used, the splicing surface of the right shell 2 and the left shell 1 needs to have higher precision. The device does not have to worry about the shaking of the transmission member and the electromagnetic coil 4 inside the disconnecting device shell, and does not need to be disassembled, so the device can reach the level of adhesive sealing. The gasket has poor thermal conductivity, the adhesive has good thermal conductivity, and the existing device relies on the gasket for sealing, which not only has poor effect, but also considers the case of not being tightly closed.
[0047] The axis of the slide column 11 coincides with the axis of the left shell 1, that is, to ensure that the slide column 11 and the openings of the left shell 1 and the right shell 2 maintain the same axis, and through the addition of the pre-tightening column 3, the axis of the pre-tightening column 3 also maintains parallel with the central axis, ensuring that the pre-tightening force of the pre-tightening column 3 will not be skewed, and the electromagnetic coil 4 can be evenly and smoothly pressed in the left shell 1, achieving a stable effect;
[0048] The electromagnetic coil 4 is circular, and the electromagnetic coil 4 is sleeved outside the slide column 11. The left end face of the electromagnetic coil 4 abuts against the side wall of the inner cavity of the left shell 1.
[0049] A plurality of limiting holes 21 are formed in the right shell 2, the limiting holes 21 are closed circular holes, the left side of the limiting hole 21 is open, the opening of the limiting hole 21 is formed on the left splicing surface of the right shell 2, and the limiting hole 21 extends to the axis. When the right shell 2 and the left shell 1 are spliced neatly, the limiting hole 21 is opposite to the cavity position of the left shell 1.
[0050] The axis of each limiting hole 21 is parallel to the axis of the right shell 2,
[0051] The two adjacent limiting holes 21 are spaced at an angle of 40°-120°, and a plurality of limiting holes 21 are distributed in a circular ring on the butt joint plane of the right shell 2 and are distributed with the axis of the right shell 2 as the center; such an angle distribution can also distribute the pre-tightening columns 3 in the limiting holes 21 at intervals, so that the annular surface of the electromagnetic coil 4 can be tightly pressed on the inner wall of the left shell 1, and the stress is more uniform. The reason for the range is that the disconnector shell has many other components to be assembled, and the limiting holes 21 need to avoid these assembly parts, but it is not allowed to exceed the angle design range. Generally, it is controlled at about 60° angle. When it is necessary to separate and avoid other connecting parts, it can be appropriately expanded. The included angle between any two adjacent limiting holes 21 is controlled to be not more than 90°, otherwise it will cause the pressing of the electromagnetic coil 4 to be unbalanced, and the skew will occur during long-term use. The angle design of the device can make up for this situation.
[0052] The pre-tightening column 3 is an elastic columnar structure, and one pre-tightening column 3 is inserted in each limiting hole 21. The pre-tightening column 3 is in interference fit with the limiting hole 21. The pre-tightening column 3 is an integral rubber cylinder. When the pre-tightening column 3 is installed in the limiting hole 21, it can be easily inserted and assembled, and it is not easy to fall off. It can also ensure that the pre-tightening column 3 is more stable after installation.
[0053] The pre-tightening column 3 protrudes to the left side on the splicing surface of the left shell 1. The length s of the pre-tightening column 3 extending out of the limiting hole 21 is between 1-5mm.
[0054] The thickness of the electromagnetic coil 4 is less than the left-right direction depth of the inner cavity of the left shell 1. The electromagnetic coil 4 is arranged inside the cavity of the left shell 1. The left end of each pre-tightening column 3 abuts against the right end surface of the electromagnetic coil 4. The electromagnetic coil 4 is clamped in the inner cavity of the left shell 1 by the pre-tightening column 3. Such a design can conveniently assemble and stabilize the electromagnetic coil 4 inside the left shell 1, without considering the tolerance. All assembly parts inside the left shell 1 and the right shell 2 which are dynamically adsorbed with the electromagnetic coil 4 are tightly abutted by the pre-tightening column 3, to ensure the installation stability.
[0055] The electromagnetic coil 4 is fixed inside the left shell 1. The object adsorbed by the electromagnetic coil 4 is generally a sliding ring made of a magnetic induction material, which is also designed inside the complete shell. The pressing of the electromagnetic coil 4 by the device can also ensure the stability of the adsorption position of the sliding ring. Otherwise, the left-right shaking of the electromagnetic coil 4 can easily cause the position accuracy of the sliding ring in the disconnector. This cannot accurately judge whether the stabilizing rod is completely disconnected or in a completely engaged transmission state. The sealing of the shell of the entire stabilizing rod disconnector is very important, and the position of the transmission device and the sliding ring of the disconnector is also very important. Both of them need the installation stability of the electromagnetic coil 4 and the sealing of the splicing of the left shell 1 and the right shell 2 to be guaranteed.
[0056] The utility model discloses when using, the electromagnetic coil 4 is placed in the left shell 1 inside, and the right side end face of electromagnetic coil 4 is retracted in the left shell 1 cavity inside, and the retraction size should be less than the size of pre -tensioning column 3, and the retraction size of electromagnetic coil 4 can select 0.5mm, and the length s of pre -tensioning column 3 left bulge can be 2mm, thereby increasing certain pre -tensioning force for electromagnetic coil 4, ensure that electromagnetic coil 4 is in the compression state continuously.
[0057] Then install other fittings, and after the assembly of the parts inside the disconnecting device is completed, the left shell 1 and the right shell 2 are folded, then the splicing surface is coated with adhesive, the splicing seam is sealed, and a bolt is placed in each lock mounting hole 12, then a nut or an internal thread is placed in the butt joint hole 22, and the left shell 1 and the right shell 2 are assembled and locked through the locking of the bolt and the nut or the internal thread.
[0058] When the adhesive is applied to the sealing end face of the shell, the line diameter of the adhesive is controlled to be 1.0-2.0mm, and the adhesive track is reasonably planned to ensure that the adhesive is continuous and the sealing property is ensured.
[0059] The left and right of the device refer to the left and right sides of the vehicle when the device is installed on the vehicle. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
