Description

Connecting rod structure for transverse stabilizer bar and transverse stabilizer bar assembly

Technical Field

The utility model belongs to the field of automobile part design, and particularly relates to a connecting rod structure for a transverse stabilizer bar and a transverse stabilizer bar assembly.

Background

The cross arm type suspension is an independent suspension with wheels swinging in a transverse plane of the automobile, the double cross arm type suspension is a suspension system with two cross arms, and the double cross arm type suspension is used for transmitting force and moment acting between the wheels and the frame, buffering impact force transmitted to the frame or the automobile body by an uneven road surface and reducing vibration caused by the impact force so as to ensure that the automobile can run smoothly;

the rigidity value designed by the existing double-wishbone suspension stabilizer bar is basically unchanged in the whole suspension movement stroke. When the suspension is in a general working condition and the stabilizer bar is not needed to be inserted, the stabilizer bar still provides larger roll stiffness, and the running smoothness of the whole vehicle is reduced. Under extreme working conditions, the stabilizer bar is expected to provide larger roll stiffness, and the roll stiffness of the stabilizer bar cannot be greatly improved due to the influences of suspension stroke, linear stiffness characteristics of the stabilizer bar and the like.

Under the two working conditions, the rigidity requirements of the stabilizer bar are greatly different. Thus, the linear stiffness design of the stabilizer bar may be greatly limited. This disadvantage is particularly evident on short wheel jump travel or large mass vehicles.

In order to more clearly demonstrate the structure, referring to fig. 1, fig. 1 is a schematic diagram of a connecting rod structure 100 for a stabilizer bar and a peripheral member in a connected state according to an embodiment of the present utility model.

As can be seen, the link structure 100 is referred to as a middle connector of the swing arm structure (not shown) and both ends of the stabilizer bar 200 in the embodiment of the present utility model.

In some embodiments, the stabilizer bar 200 may be connected to other parts of the left and right suspensions, such as an automobile shock absorber or a support arm;

it can be understood that when the vehicle runs straight and the left and right wheels jump up and down at the same time, the vehicle body only moves vertically, the deformation of the left and right suspensions is equal, and the stabilizer bar 200 does not work; when the vehicle turns, since the wheel suspension on the outer side is in a compressed state and the wheel suspension on the inner side is in an expanded state when the vehicle turns, the buckling deformation occurs when the stabilizer bar 200 is pressed, and the stabilizer bar 200 is pressed by a force opposite to the respective movement directions, so that the deformation is suppressed.

Fig. 2 is a schematic view illustrating a hard spot of the stabilizer bar 200 and the bar connecting structure 100 in fig. 1 in a connected state.

It can be seen that the hard points B and C constitute moment arms when subjected to a roll force that causes the stabilizer bar 200 to begin to squeeze the bar linkage 100, the bar linkage 100 producing a force in the direction of hard point B to hard point a. It is thus desirable for the present utility model that the stabilizer bar 200 not provide a large roll stiffness when normal conditions occur, but that the stabilizer bar 200 be able to provide a large roll stiffness linearly according to the magnitude of the roll force when roll occurs.

On the basis of fig. 1 and 2, please refer to fig. 3 to 4, fig. 3 is an exploded view of the connecting rod structure 100 for the stabilizer bar 200 according to the embodiment of the utility model, and fig. 4 is a cross-sectional view of the connecting rod structure 100 according to the embodiment of the utility model.

The connecting rod structure 100 comprises a rod body 11, a cylinder barrel structure 12, a sliding block 13, a buffer structure 14, a gasket 15, a fixing bolt 16, a first sleeve 17, a second sleeve 18 and an end cover 19;

each component is described one by one as follows:

the rod body 11 is preferably cylindrical, one end of the rod body is indirectly connected with the transverse stabilizer rod 200, and the rod body is mainly used for realizing torque transmission by utilizing the axial movement of the rod body;

the cylinder barrel structure 12 is a hollow shell structure, in particular a columnar body, and the interior of the cylinder barrel structure is a columnar cavity 121;

the sliding block 13 is connected inside the cylindrical cavity 121 in a sliding manner, and the sliding block 13 is connected to the other end of the rod body so as to axially move along the cylindrical cavity 121 along with the transverse stabilizer bar 200;

wherein the slider 13 is located in the middle of the cylindrical cavity 121 in the first state;

in the second state the slider 13 moves down and indirectly abuts against the bottom of the cylindrical cavity 121.

It will be appreciated that the first state refers to a "vehicle is not producing a condition that requires participation by the stabilizer bar 200" when the link structure slider 13 is in a neutral position of the cylindrical cavity 121. In the first state working condition, the sliding block 3 does not play a role in transmission;

it will be appreciated that by loading verification, controlling the position of the stabilizer bar 200 achieves that the slider 13 is located in the middle of the cylindrical cavity 121 in the first state. As can be seen from fig. 1 to 2, in the first state, the stabilizer bar 200 is in a free state in the vertical point connecting line direction. At this time, the stabilizer bar does not provide the roll moment. Avoiding affecting the running smoothness of the vehicle.

The second state refers to a state where the vehicle needs to rely on the stabilizer bar 200 to provide a greater roll stiffness to avoid roll when the up-down jump reaches the set value, and the slider 13 starts to move down under the action of the stabilizer bar 200 and contacts the bottom of the cylindrical cavity 121 indirectly so that the force of the stabilizer bar 200 is transmitted to the swing arm structure. Since the stabilizer bar stiffness is in series relationship with the link structure stiffness, the roll stiffness begins to compress downward with the slider 13 and the stabilizer bar 200 begins to intervene.

Therefore, the present utility model can achieve improvement of traveling smoothness in straight traveling and in a limit state without providing roll stiffness when no intervention of the stabilizer bar is required by improving the link structure 100 of the stabilizer bar 200; the roll rigidity of the transverse stabilizer bar 200 can be greatly improved when the roll happens, different working condition requirements are met, the roll of the vehicle can be better avoided particularly on vehicles with short wheel jump travel or large mass, and the running safety of the vehicle is ensured.

With continued reference to fig. 3, to provide stable contact between the slider 13 and the cylinder structure 12, the interior of the cylindrical cavity 121 needs to be provided with a cushioning structure 14 to provide cushioning when the slider 13 presses the bottom of the cylindrical cavity 121 at the contact surface, avoiding contact collapse of the rigid structure directly under high torque.

In this embodiment, the buffer structure 14 includes:

a damping plug 141, the damping plug 141 being connected to the upper surface of the slider 13 to provide a buffering damping force when the slider 13 is pushed against the upper surface by the rod 11 pulling up the slider;

a rebound stopper 142, the rebound stopper 142 being provided at the bottom of the cylindrical cavity 121;

when the slider 13 moves down, the lower surface of the slider 13 is compressed by the rebound stopper 142 to achieve a cushioning effect.

It will be appreciated that the upward or downward movement of the slider 13 depends on the roll direction of the vehicle, and assuming that fig. 4 is a link structure 100 on the right side of the vehicle body, when the vehicle is rolled on the right side, the slider 13 is rapidly moved downward by the pressing of the rod 11, whereas when the vehicle is rolled on the left side, the slider 13 is moved downward by the driving of the rod 11.

It will be appreciated that the vehicle is rolling left/right when the up-down jump reaches the set point, the slider 13 contacts the damper plug 141 or rebound stopper 142 and begins to squeeze. Because the rigidity of the stabilizer bar and the rigidity of the connecting rod structure are in series connection, the rolling rigidity starts to rapidly rise (nonlinear section) along with the compression of the limiting block. When the damper plug 141 or rebound stopper 142 is compressed to a limit, the link structural rigidity tends to be infinite, after which the roll rigidity of the entire vehicle reaches a maximum. The roll stiffness curve then tends to be linear.

With continued reference to fig. 3 to 5, fig. 5 is a schematic structural diagram of the damping plug 141 and the slider 13 according to the embodiment of the present utility model.

The sliding block 13 comprises a first mounting column 131, the rod body 11 is provided with a mounting hole 111 towards the sliding block 13, and the rod body 11 and the sliding block 13 are fixedly connected through the first mounting column 131 and the mounting hole 111 in a threaded connection mode.

It can be understood that the bottom of the rod 11 is directly provided with a threaded mounting hole 111, the first mounting post 131 is a stud, and the slider 13 is directly screwed into the mounting hole 111 through the first mounting post 131 to achieve connection with the rod 11.

Further, the slider 13 and the first mounting post 131 are integrally formed, and the first mounting post 131 is directly formed by the swivel body processing. To reduce assembly steps, increase efficiency and reduce the likelihood of abnormal sound.

In some embodiments, the slider 13 may also be integrally formed directly with the rod 11.

The damping plug 141 may be vulcanized directly to the upper surface of the slider 13 using polyurethane or rubber, so that the gap between the damping plug 141 and the slider 13 can be reduced, and the diameter of the damping plug 141 is slightly smaller than that of the slider 13 to reserve a space in which the damping plug 141 is compressed in the radial direction.

It can be appreciated that, since the damping plug 141 can slide axially along with the slider 13, when the damping plug 141 is extruded, it is required to ensure that the damping plug does not form interference contact with the inner wall of the cylinder barrel structure 12, so that a certain space needs to be reserved in the radial direction, so that the situation that the slider 13 cannot move down is avoided, and the continuous reliability of the stabilizer bar 200 is increased.

Still further, the slider 13 is also provided with a vent groove 132, the vent groove 132 being provided on the outer peripheral surface of the slider 13 and being provided in the radial direction, which penetrates the entire outer peripheral surface so as to be provided.

It will be appreciated that the vent grooves 132 serve to avoid the formation of a high pressure environment within the cylindrical cavity 121 of the cylinder structure 12, and to avoid the slider 13 from moving axially, resulting in an increase in air pressure within the cylinder structure 12, thereby disabling movement of the slider 13 under air pressure.

Still further, the link structure 100 further includes a washer 15 and a fixing bolt 16;

a spacer 15 is provided on the underside of rebound stopper 142 to provide support for rebound stopper 142;

referring to fig. 4, the cylindrical cavity 121 is provided with a recess 1211 corresponding to the fixing bolt 16, and the fixing bolt 16 is fixed in the recess 1211 by passing through the rebound stopper 142 and the spacer 15.

Wherein the first sleeve 17 and the rod body 11 are integrally formed for connection with the stabilizer bar 200 in a radial direction along the cylinder structure 12;

the second sleeve 18 is likewise integrally formed with the cylinder structure 12 for connection with the swing arm structure in a radial direction along the cylinder structure 12.

The link structure 100 further includes:

the end cap 19, the end cap 19 is connected to the upper side of the cylinder structure 12, in particular can be screwed to the upper side of the cylinder structure 12 by screwing, which serves to close the cylindrical cavity 121. With further reference to fig. 3, the end cap 19 is provided with a through hole 191, the through hole 191 being used for the passage of the rod 11 and for its guiding function.

Therefore, the connecting rod structure 100 provided by the embodiment of the utility model has the advantages of simple structure, less assembly positions and small assembly process difficulty.

Based on the structure, the rigidity of the transverse stabilizer bar 200 is set to be K _s The rigidity of the connecting rod is K _l If the included angle between the axis of the connecting rod and the Z axis of the whole vehicle is alpha, the Z-direction rigidity K of the point A is alpha _A The method comprises the following steps:

k when the slider 13 does not contact the damper plug 141 or the rebound stopper 142 _l =0, at this time K _A When the stopper=0 comes into contact with the damper plug 141 or the rebound stopper 142, K _l And gradually increases along with the limit compression stroke. Thus, K is _A The rigidity is gradually improved, and the rigidity curve after limiting contact is in a nonlinear state;

when K is _l Tend to be infinite, K _A ＝K _s ×cosα。

Therefore, if the front suspension stabilizer bar is of a common structure, the rigidity is 150N/mm. With the link structure 100 provided in the embodiment of the present utility model, the rigidity of the stabilizer bar 200 can be set to 450N/mm or more. In the case where the contact front stroke setting of the slider 13 of the link structure 100 is reasonable, the stabilizer bar rigidity generally does not have any influence on the roll rigidity of the entire vehicle.

Secondly, by adjusting the shape and the height of the limiting block, a nonlinear stiffness curve can be freely set according to the requirement. Even the damping plug 141 can be lengthened to make the slider directly contact in the 1G working condition, at this time the stabilizer bar takes part in the adjustment in the whole course, the rigidity starts from a smaller value, and the rigidity is lifted at a gentler rate.

The rigidity of the transverse stabilizer bar 200 can be improved by modifying the connecting rod structure 100, and the limitation of the linear rigidity of the transverse stabilizer bar 200 is broken through in a mode that the nonlinear rigidity is connected with the linear rigidity in series;

on the other hand, by replacing the slider 13 in the link structure 100, it is possible to adapt to different vehicle types, so that the stabilizer bar versatility is improved; and the movement stroke of the stabilizer bar is reduced, and the movement gap between the stabilizer bar and the peripheral parts can be reduced.
