Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile stabilizer bar, especially to a torsional sealing kit on stabilizer bar and disconnecter. BACKGROUND

[0002] The transverse stabilizer bar, also known as stabilizer bar, anti-roll bar or balance bar, is an auxiliary elastic element in the automobile suspension and is an indispensable mechanical structure for balancing the left and right sides of the automobile.

[0003] The function of the transverse stabilizer bar is to prevent the vehicle body from excessive lateral roll when turning and to keep the vehicle body as balanced as possible. The purpose is to reduce the degree of lateral roll of the automobile and to improve the smoothness. The transverse stabilizer bar is actually a transversely placed torsion bar spring and can be regarded as a special elastic element in function. When the vehicle body only makes vertical movement, the deformations of the left and right suspensions are the same, and the transverse stabilizer bar does not work. When the vehicle turns, the vehicle body rolls, and the left and right suspensions do not jump uniformly. The outer side suspension will be pressed against the stabilizer bar, and the stabilizer bar will be twisted. The elastic force of the bar body will prevent the wheels from lifting, thereby keeping the vehicle body as balanced as possible and playing a role in lateral stabilization.

[0004] The current stabilizer bar is basically an integral elastic torsion bar, which is a whole structure. Although this stabilizer bar effectively prevents vehicle roll and provides more stable driving assistance for the vehicle, the suspension travel between the left and right sides of the vehicle is limited due to the restriction of the stabilizer bar. Because of the restriction of the stabilizer bar, the vehicle needs to keep the left and right sides relatively stable and basically in a whole plane. When the vehicle encounters uneven road surfaces, the ground is not in the same plane, especially when encountering potholes, it is easy to cause the wheels to be suspended, especially when the front and rear wheels stagger over the potholes. The vehicle is restricted by the stabilizer bar, and the two wheels above the potholes cannot contact the ground, resulting in power failure of the vehicle. Even four-wheel drive vehicles are very difficult to escape from such a pothole road. In this case, the stabilizer bar needs to be separated to allow the vehicle shock absorber to have a larger stroke and enable more wheels to contact the ground to generate power to facilitate the vehicle to escape.

[0005] This split stabilizer bar becomes an indispensable auxiliary accessory for off-road vehicles to escape. When the vehicle wheels are suspended on a pothole road, the left and right sides of the stabilizer bar can be controlled to be separated, so that the vehicle is not restricted by the stabilizer bar, allowing the wheels to have a larger lifting stroke and providing power to the vehicle. When the vehicle is on a paved and smooth road, the left and right sides of the stabilizer bar need to be controlled to be stable and connected as a whole to ensure the stability of the vehicle when driving at high speed.

[0006] The disconnecting device needs to be arranged in the middle of the stabilizer bar, and the stabilizer bar is also made into two sections, and the two sections of the stabilizer bar need to be controlled to be disconnected or connected through the disconnecting device, and the connection between the two sections of the stabilizer bar and the disconnecting device will relatively rotate when the connection needs to be disconnected, and a rotatable sealing element needs to be used to rotate and seal the connection between the stabilizer bar and the disconnecting device. This sealing is different from the conventional sealing, and not only the lubricating oil in the disconnecting device needs to be prevented from leaking out, but also the external contaminants or muddy water needs to be prevented from penetrating into the disconnecting device when the connection between the stabilizer bar and the disconnecting device relatively rotates, and there are many difficulties in actual operation, especially when a mechanical seal is used, although the mechanical seal can relatively rotate, but once the stabilizer bar bears a large bending moment, the external contaminants can easily enter the disconnecting device.

[0039] Please refer to Figures 1 to 5 The utility model provides a torsional sealing sleeve on stabilizer bar and 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.

[0040] In the utility model technical scheme one specific embodiment:

[0041] Including shell 1, ring hoop 2, stabilizer bar 3 and sealing cover 4;

[0042] Shell 1 is the sealing housing of disconnecter on the vehicle transverse stabilizer bar, and the both ends of shell 1 are outwardly provided with one butt joint pipe 12, the butt joint pipe 12 extends to the outside of shell 1 towards both ends, and one annular shell clamping groove 11 is formed on the outer wall of butt joint pipe 12;

[0043] The transmission end of stabilizer bar 3 is a straight rod, and the left and right sides of stabilizer bar 3 are disconnected, and the transmission end of the left and right sides of stabilizer bar 3 is inserted into the transmission inside shell 1;

[0044] Annular rod clamping grooves 31 are formed on the outer walls of the left and right sides of stabilizer bar 3;

[0045] Sealing cover 4 is a closed sealing pipe sleeve with open ends, and sealing cover 4 is a flexible overall structure;

[0046] One end of sealing cover 4 is rod end sleeve 41, and the other end of sealing cover 4 is shell end sleeve 42, and sealing cover 4, rod end sleeve 41 and shell end sleeve 42 are integrated sealing structures;

[0047] The rod end sleeve 41 and the shell end sleeve 42 at both ends of the sealing cover 4 are arc-shaped necks;

[0048] A plurality of arc-shaped convex rib frameworks 44 are outwardly provided on the sealing cover 4 between the rod end sleeve 41 and the shell end sleeve 42, the convex rib frameworks 44 are arc-shaped protrusions on the side walls along the axis direction of the sealing cover 4, the convex rib frameworks 44 are higher at the middle and lower at both ends, the plurality of convex rib frameworks 44 are evenly arranged around the side walls of the sealing cover 4, and the connection between the both ends of each convex rib framework 44 and the rod end sleeve 41 and the shell end sleeve 42 is arc-shaped.

[0049] The outer diameter of the rod end sleeve 41 and the shell end sleeve 42 is less than the outer wall diameter of the sealing cover 4 at the groove 46, and the outer wall diameter of the sealing cover 4 at the groove 46 is different from the diameter of the rod end sleeve 41 and the shell end sleeve 42 by not less than 5 mm; the sealing cover 4 and the rod end sleeve 41 and the shell end sleeve 42 form a lantern-shaped structure; the outer wall of the sealing cover 4 forms a lantern shape; the sealing cover 4, the rod end sleeve 41 and the shell end sleeve 42 are integrally formed as a whole rubber sleeve. The two adjacent ridge skeletons 44 are inwardly recessed grooves, forming straight grooves along the axial direction, and the plurality of ridge skeletons 44 and the grooves arranged therebetween form a circular ring-shaped fold along the axial direction; such a structure has a fold formed by the cooperation of the groove and the ridge skeleton 44, which can expand or contract along the cylindrical outer wall, forming more deformation amount.

[0050] The wall thickness of the sealing cover 4 at the groove 46 is less than the wall thickness of the ridge skeleton 44, with a difference in the range of 0.5-2 mm. By changing the wall thickness, the fold groove of the sealing cover 4 forms an expandable shape, and the sealing cover 4 has stronger support by the ridge skeleton 44, so as to achieve the combination of support and deformation, and to mutually compensate for the defects of stress, so that the whole sealing cover 4 has stronger sealing effect, and can cooperate with the stable rod 3 and the shell 1 to produce rotational deformation, and in the deformation process, the two ends of the sealing cover 4 remain in a sealed state with the stable rod 3 and the shell 1, that is, the sealing cover 4 can rotate between the two stable rods 3 while maintaining the sealing effect of the shell 1.

[0051] The outer wall of the rod end sleeve 41 and the shell end sleeve 42 is provided with a positioning groove 45;

[0052] The shell clamping groove 11, the rod clamping groove 31 and the positioning groove 45 are all inwardly recessed open grooves; the positioning groove 45 on the rod end sleeve 41 is sealingly embedded and clamped outside the rod clamping groove 31; the positioning groove 45 on the shell end sleeve 42 is sealingly embedded and clamped outside the shell clamping groove 11;

[0053] The shell 1, the stable rod 3, the sealing cover 4, the rod end sleeve 41 and the shell end sleeve 42 are on the same axis;

[0054] The inner wall of the rod end sleeve 41 and the shell end sleeve 42 is inwardly provided with a plurality of clamping lines 43, and the plurality of clamping lines 43 are annular protruding lines parallel to each other, the axis of the clamping lines 43 coincides with the axis of the sealing cover 4, and the clamping lines 43 on the rod end sleeve 41 and the shell end sleeve 42 are embedded in the shell clamping groove 11 or the rod clamping groove 31;

[0055] The rod end sleeve 41 is in interference fit with the rod clamping groove 31, the shell end sleeve 42 is in interference fit with the shell clamping groove 11, the outer part of the rod end sleeve 41 and the shell end sleeve 42 are sleeved with the ring 2, the rod end sleeve 41 is locked with the ring 2 through the ring 2, and the shell end sleeve 42 and the shell clamping groove 11 are also sealed and locked through a ring 2. The clamping groove 43 is on the inner wall of the positioning groove 45, so that the ring 2 and the positioning groove 45 cooperate with the clamping groove 43 to bear the force on the corresponding annular groove of the stabilizer bar 3 or the shell 1, and the clamping is more stable.

[0056] It should be noted that:

[0057] 1. The existing mechanical movable sealing element seals the disconnector and the stabilizer bar 3. This mechanical seal is achieved by keeping the dynamic ring and the static ring closely combined through the relative rotation surface, and the lubricating oil forms an oil film on the rotation surface, which plays a sealing effect on the dynamic ring and the static ring. Once the radial and axial bidirectional torque occurs, the mechanical seal cannot deform to follow the sealing, and leakage is likely to occur. The mechanical seal is more to prevent the internal lubricating oil from leaking out, and the sealing effect from the outside to the inside is not ideal. This structure is easy to cause the entry of external particles or water into the stabilizer bar disconnector when the stabilizer bar needs to be disconnected in a muddy mountain road or the vehicle wades in deep water, which will cause the lubricating oil in the disconnector to emulsify, and even rust, which will bring danger to the subsequent vehicle driving;

[0058] 2. Some rubber sleeves are also used to seal the stabilizer bar 3 and the shell 1. Generally, a stepped sleeve is used to cooperate with the diameter of the shell 1 and the stabilizer bar 3. The axial and radial torsional force of this rubber sleeve sealing sleeve is ordinary, and it cannot meet the demand of large stroke. The relative rotation angle of the rubber sleeve itself is generally not more than 10°, and the torsional range of the stabilizer bar 3 on the left and right sides. When the torsional force exceeds the bearing capacity of the rubber material itself, the rubber sleeve at both ends will slide relative to each other, or the rubber sleeve will be twisted and extruded, which will cause the sealing effect to be temporarily invalid until it returns to its original state. Even if the stabilizer bar 3 finally returns to its original position, the sealing sleeve can no longer achieve the original sealing effect.

[0059] In order to avoid the above situation, the device uses a static rubber seal cover 4, the rod end sleeve 41 and the shell end sleeve 42 at both ends of the seal cover 4 are locked with the stabilizing rod 3 and the disconnecter shell 1, and when the stabilizing rods 3 on both sides need to be disconnected and twisted, the seal cover 4 of the device can be deformed by a larger amplitude through the neck-like rod end sleeve 41 and the shell end sleeve 42, the grooves between the convex rib skeletons 44, to cooperate with the relative rotation of the stabilizing rods on both sides by a larger angle. And through the positioning groove 45 cooperating with the rod clamping groove 31 and the shell clamping groove 11, the recess is limited, the sealing is more effective, and through the torsional deformation of itself, the torsional stroke requirement of the stabilizing rod 3 is met, so that the rod end sleeve 41 and the shell end sleeve 42 at both ends do not need to rotate, but buffer deformation through the grooves between the convex rib skeletons 44, and the wall thickness of the grooves is smaller, and the deformation is easier. Because of the lantern-like structure of the device, the middle section of the seal cover 4 provides a larger radial torsional deformation amount, and adapts to the more torsional angle of the stabilizing rods 3 on both sides.

[0060] And the convex rib skeletons 44 can make the seal cover 4 produce a larger rotary force, and after the deformation is completed, the seal cover 4 will not be irreversibly damaged, but will rebound to the initial state, providing effective sealing of the stabilizing rod 3 in a static state. The device can effectively maintain effective sealing in both directions under harsh environments.

[0061] When the stabilizing rods 3 on both sides are connected to keep a relative static connection state through other transmission mechanisms, the seal cover 4 remains stationary and is in a static state, at this time, the positioning groove 45 of the rod end sleeve 41 of the seal cover 4 is locked in the rod clamping groove 31 of the stabilizing rod 3, and the positioning groove 45 of the shell end sleeve 42 is embedded in the shell clamping groove 11 of the shell 1, and both are locked by the ring 2, effectively maintaining static sealing.

[0062] When the stabilizing rods 3 on both sides are connected to keep a relative static connection state through other transmission mechanisms, the seal cover 4 remains stationary and is in a static state, at this time, the positioning groove 45 of the rod end sleeve 41 of the seal cover 4 is locked in the rod clamping groove 31 of the stabilizing rod 3, and the positioning groove 45 of the shell end sleeve 42 is embedded in the shell clamping groove 11 of the shell 1, and both are locked by the ring 2, effectively maintaining static sealing.

[0063] When the stabilizing rods 3 on both sides are connected to keep a relative static connection state through other transmission mechanisms, the seal cover 4 remains stationary and is in a static state, at this time, the positioning groove 45 of the rod end sleeve 41 of the seal cover 4 is locked in the rod clamping groove 31 of the stabilizing rod 3, and the positioning groove 45 of the shell end sleeve 42 is embedded in the shell clamping groove 11 of the shell 1, and both are locked by the ring 2, effectively maintaining static sealing.

[0064] Although the specific embodiments of the present application are described above, those skilled in the art should understand that the specific embodiments described by us are only illustrative, not for limiting the scope of the present application, and equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present application should be covered within the scope of the claims of the present application.
