Description

The utility model relates to the field of transport engineering, namely to devices for stabilizing the lateral stability of vehicles.

Known stabilizer rack, consisting of a round metal bar, to one of the ends of which an eyelet is welded, which is a tube, inside which a silent block is installed. A metal rectangular plate with edges bent from both sides to the top is welded to the other end of the round bar. Round through holes are made in the plate, through which a bracket is fixed to it with the help of bolts and nuts. Between the plate and the bracket there is a rubber bushing with a through round hole through which the stabilizer bar is attached to the rack. The stabilizer bar is attached to the vehicle frame through the bracket using bolts and nuts

The design of the stabilizer strut described above is not reliable, since it contains relatively weak materials - metal sheets, which, when dynamic loads are perceived, can be crushed. In addition, this type of construction uses rubber bushings, which are short-lived.

Known anti-roll bar of a vehicle, consisting of a body made of a pipe and connecting two tips made with lugs. A bushing is installed in at least one of the tips, which is an axis for installing the hinge. The tips are made with a rod-shaped element for permanent connection with the tubular body (see RF patent No. 114910, IPC B60G21 / 00 (2006.01), publ. 20.04.2012).

The disadvantage of the known technical solution is the lack of reliability of its design. The empty cavity of the tubes is prone to bending; there is also a risk of opening at the points of connection with the tip tubes. In addition, the bolts are made open, which leads to dirt ingress, corrosion, damage.

Known device for stabilizing the lateral stability of the vehicle, in which taken for the prototype of the rack, contain in the lower part of the half-lugs, which are installed half silent blocks. Silent blocks are closed with overlays, fixed with bolts and nuts. At the same time, grooves are provided for fixing the half silent blocks at the lower ends of the stabilizer struts. With their upper ends, the stabilizer struts are attached to the lower flanges of the frame side members through brackets using split silent blocks, axles and nuts (see RF patent No. 183896, IPC B60G21 / 04 (2006.01), publ. 08.10.2018).

In this solution, the lugs of the posts do not have stiffening ribs at the points of their connection with the post and the lining, which reduces the strength of the structure. In addition, the holes in the lugs are made through, which leads to the ingress of dirt, dust, moisture and further corrosion on the bolts and in the hole.

The problem to be solved by the claimed technical solution is to improve the reliability of the structure of the anti-roll bar.

To solve this problem, in the anti-roll bar rack, containing a body with a cast-in upper eyelet and with a cast-in lower support part, a closed cover plate equipped with silent blocks, while the lower support part and the cover plate have bosses with holes, at the junction of the bosses with the lower part of the housing stiffening ribs, and the holes in the bosses of the lower support part are made blind.

The presence of stiffeners at the junction of the bosses with the lower part of the body increases the strength of this rack assembly. Making blind holes in the bosses of the lower bearing section prevents the ingress of dirt, dust, moisture and further corrosion on the bolts and in the hole. Taken together, these features improve the reliability of the anti-roll bar structure.

The claimed technical solution is illustrated by drawings:

fig. 1 - shows the anti-roll bar, bottom view in isometric;

fig. 2 - the upper part of the rack, bottom view in isometric;

fig. 3 - rack overlay, bottom view in isometric.

The anti-roll bar consists of a body 1 and a lining 2. Body 1 is a one-piece metal part made with a cast-in upper lug 3 and a cast-in lower support part 4. In the middle part of the body 1 along the edges there are longitudinal sides 5, which are stiffening ribs. A silent block 6 is pressed into the lug 3. The support part 4 and the cover plate 2 each have two bosses 7 with threaded holes 8 and 9 for attaching the cover plate 2 to the support part 4 using bolts 10. At the same time, at the junctions of the bosses 7 with the lower part of the body 1 stiffening ribs 11, and holes 8 in the bosses 7 of the support part 4 are made blind. The inner cavities of the support part 4 and the overlays 2 have a semicircular shape for seating half silent blocks 12.

With its upper end, the strut is attached to the lower flange of the vehicle frame side member through the bracket using a bolt and a nut. The middle part of the U-shaped stabilizer bar is suspended from the lower end of the rack.

The claimed technical solution made it possible to increase the reliability of the structure of the anti-roll bar

The claimed technical solution is possible for implementation on standard technological equipment.

Claims (1)

The anti-roll bar, containing a body with a cast-in upper eyelet and with a cast-in lower support part, closed by an overlay, equipped with silent blocks, while the lower support part and the overlay have bosses with holes, characterized in that ribs are made at the junction of the bosses with the lower part of the body rigidity, and the holes in the bosses of the lower support part are made blind.
