Upper support for vehicle suspension spring strut guide

The utility model relates to transport engineering, namely to vehicle suspensions.

Known support elastic and damping elements of the vehicle suspension, containing the outer and inner cages, between which there is an elastic element, and an elastic krypps mounted on the outer cage, and on the inner cage from the side of the elastic element protrusions are made with decreasing towards the elastic krypps height and bar while the latter is reinforced with an elastic retaining ring mounted in a groove that is made on the outer ring, and the lower part of the valve is made with an annular height blunt with a profile corresponding to the profile of the elastic element at the upper edge and the outer cage (analogue - AS USSR No. 1220934 V 60C 11/00).

A disadvantage of the known support is that it has a linear stiffness characteristic in the vertical direction.

Known is the upper rigid attachment system of the shock absorber strut having a rolling bearing with an annular insert of elastomeric material vulcanized to its inner ring, on the inner wall of which a metal sleeve is vulcanized. An insert made of elastomeric material is vulcanized on the outer ring of the bearing, which has an annular shape and is connected from its outer side to the bearing housing by means of vulcanization, which is in rigid connection with the automobile body (analogue of German application No. 3204816 В 60С 15/06).

The disadvantage of this solution is that during the operation of the car low stiffness characteristics of the support appear, since the insert made of elastomeric material, especially at maximum travels of the wheel suspension, has an almost linear stiffness characteristic in the vertical direction.

The closest technical solution is the upper support of the guide spring suspension of the car, containing subshpnik located between the elastic annular insert, vulcanized by its outer side to

the support housing, and an elastic ring-shaped hinge, on the inner wall of which a sleeve is vulcanized, in which a flange of the flange is fixed with a Tcpiy flange installed on its lower end and contact with the flange of the flange of the support; bearing and the enclosing insulating shchukpadEO of the spring, 4p compression located on a rod, and the bearing is installed in a cage, vulcanized to an elastic ring-shaped insert, and a part of the internal surface of the inner to The bearing rings and the inner surface of the support center flange of the upper spring cup pressed into it flush form a ring with an elastic ring-shaped PB mounted in the press, having an upper and lower ring-shaped protrusions from the strained side, which covers the upper part of the inner ring and the upper part respectively inner noBqpxHOcra of the upper spring cup, on the 1st side of the n) on the right sides of the upper and lower ledges there are bevels Ocpona), and in addition the upper ledge is completely p it is located under the bottom of the end stop of the rebound stroke, and the lower protrusion, made thicker and of a larger diameter than the top vytyup, is completely located above the washer installed between the rod protrusion and the lower end B1 of the uzrushgo bag, the data center of which is raffled buff (cathy, and in the insulating spring gasket an insert made of solid material was vulcanized (schllogap - Russian Patent No. 2090378 B 60G15 / 06).

The main disadvantage of this solution is the complexity of the design, which has a large number of elements, large frames, the insufficient use of all syuysga uglichnyh zolentov to increase dgmpfirshchyushchsh.

The objective of the utility model is to refine the structure, reduce the size of the dummy blocks, and increase the efficiency of the work.

The lower part of the inner casing, starting from the zone where the lower end of the sub-fern is located, as well as in zone x) of the actor line of inflection, has slopes and is made to tear down (L) often) up)

Comparison of the claimed technical solution with the state-of-the-art in scientific and technical and final decision as of the date of the report shows that the set of essential features of the proposed solution was not previously known, therefore it corresponds to the condition of the praggenability “novelty.

The unified technical solution is very much feasible, since it can be manufactured industrially, efficiently, ocynijBCTBHMO, and is manufactured in kind, therefore it meets the condition for being able to work.

FIG. 1 - clarifying support, longitudinal section;

Fig.2 supreme support.

The supreme support of the direct outfit rack of the transverse suspension, includes the outer casing 1, the upper casing 2, the axial inside axial, the bearing 3, the corrugated element 4, the stopper limiter 5.

The elastic element 4 is installed between the outer 1 and the inner 2 bodies and is tfivolcanic to them. The cradle 3 is covered by B1, the outer one 2 and is located between the lower end of the end stop 5 and the upper cup of tfuzhina 9. The lower part 6 of the tofu element 4 has a slope of Otol a) from the periphery to the fastened corgus and tfimes to the base along the pfimeter in the area of the characteristic inflection line (zone O ) inner case. The elastic element 4 in its upper part, overlapped by the peripheral 1-fayes of the end stop 5, has at least eight radially oriented protrusions 7, the width of each of which corresponds to the distance (b) between the protrusions, and the height (h) is from 1/2 to 2 / 3 ppfins of the protrusion The lower part of the inner housing 2, starting from the zone of location of the lower torp of the bearing, as well as in zone x) of the keg line of the inflection, has slopes (angles p, y, respectively) and is made to puff the lower part 6 of the utfug element.

The work of the Ministry of Education and Science of the Republic of Belarus (m.

When the vehicle is moving under normal road conditions, the vibrations transmitted from the rod of the rack and from the rod 10 through the upper cup 9 are partially damped both in the lower part of the elastic wire 4 and in its upper part. Moreover, in its monolithic part, low-frequency oscillations are more often damped, and in the upper part, to a greater extent

high frequency oscillations. Work takes place both on the road and on the burn.

When the possibilities of the upper part of the elastic eeyeng (with an increase in the suspension travel) are exhausted, the progressive characterization of the upper support remains due to the fact that the burning occurs along the lower part of the angular element, which has a slope, due to which, with different loads, different sizes pshshddi lower part of ynjjyroro element.

In particular, when the rod moves downward, the load from it through the inner case 2 is transferred to the middle part of the elastic element 4, loading it with shear, and the stop switch of the attack 5 first acts on the radially oriented projections 7 - crushing them, and then acting on the upper monolithic part of the elastic element. XE5) akgd) the source of stiffness in the latter becomes quite gfresresashnoy, which is required for the protection of such loads.

When tptok moves upward, the load from it is transmitted through the inner case to the middle part of the elastic element 4, shearing it, and the lower part of the elastic zigzent is strained to compress the contact with the adjacent part of the inner case. The greater the load, the bolder the lower part of the elastic element will get into compression work, as a result of the fact that the adjacent part 8 of the inner casing 2 begins to interact, respectively, with a large section of the slope of the lower part of the elastic snake crumpled by it in this moment.

In case of heavy loads (for example, if the car is fully loaded), when the entire area of the lower part of the elastic element is used in the work, the stiffness characteristic of the upper support becomes quite progressive, which is required, as in the case described above , to compensate for such loads.

Since the loads during the compression course and the loads during the course of the attack, therefore, especially x) support aceristics in the direction of compression should also be higher than during the rebound. This condition is ensured by the fact that the lower part of the damaged element, according to the mass of the prestressing upper part), is the part yiqjyroro of the element.

It is possible to carry out retupirov x zegerisgik supports in the upper part by changing the size of the protrusions and their number, in the lower part by changing the angle between the lower part of the elastic element and the tightening part 8 of the inner corset, as well as the lower part of the elastic element.

Thus, the stiffness of the upper support varies depending on the values of the areas that have come into operation, the lower part of the elastic element and the adjoining part В1оареннеапо

KopiQca, and happy new year 1.

The proposed design is easy to manufacture, because the slope Opsh y) in the area of the lower end of the chipper makes it possible to bring the tool for plastic deformation of the metal in order to fill the bearing.
