专利说明:

The invention relates to vehicle suspensions and, in particular, to independent suspensions of four-wheeled vehicles. . Known for the suspension of a four-wheeled vehicle 3 comprising front and rear trailing arms connected to wheels, transversely arranged torsions connected to said arms, and a longitudinal link, the ends of which are pivotally connected to vertical arms, rigidly fixed to torsions
This suspension design, due to the 15 direct connections of the left and right wheels with common torsion bars, causes significant angular vibrations when moving the vehicle in both longitudinal and transverse planes.
In addition, this design complicates the layout of the engine compartment, trunk, body floor and Doorways, since the kinematic connection of the levers and rods 23 forces them to provide the necessary cavities.
The purpose of the invention is to increase the comfort of the vehicle by reducing its angular oscillations in the longitudinal and transverse planes.
This goal is achieved by the fact that the suspension is equipped with additional longitudinal arms located parallel to the latter under the longitudinal arms, and struts pivotally connected to the ends of the corresponding pairs of longitudinal arms, the transversely arranged torsion bars are made of two coaxially mounted parts, and the longitudinal link and vertical arms are made of two parallel to one another parts, while the ends of the parts of the torsion bars are rigidly connected with the parts of the vertical arms, the latter with the ends of the parts are longitudinal rod articulated, and of the vertical suspension arm · rear wheels are pivotally connected transverse rod, middle through which the longitudinal bar is hinged to the vehicle body.
In addition, parts of the longitudinal rod may be located in a cavity made in the lower part of the vehicle body.
The front wheels can be mounted on the racks rotatably, and the rear wheels can be mounted on the shafts mounted in the racks and connected through the transmission to the vehicle engine.
In FIG. 1 - shows the proposed suspension, side view, and part of the body; in FIG. 2 - axonometric image of the suspension; in FIG. 3 is a section AA in FIG. 2; in FIG. 4 is a section BB in FIG. 3.
The suspension, mounted on the housing 1, consists of longitudinal arms 2-5 and additional longitudinal arms 6-9, located parallel to ; but mentioned.
The outer ends of the longitudinal levers 2-9 are pivotally connected to the uprights 10-13, on which the wheels are mounted, the front ones being rotatable, and the rear ones on the shafts connected through the transmission to the vehicle engine.
The inner ends of the longitudinal arms 2-5 are rigidly connected to the transversely arranged, made of two coaxially mounted parts torsions 14-17, and the inner ends of the additional longitudinal arms 6-9 are pivotally connected to the housing 1.

FIG. 3 and Parts are put in the bottom means
The written-off design provides a condition under which, for example, shifting the right front wheel up causes the right rear wheel to shift down, which, in turn, leads to an angular displacement of the lateral link 24 to positions 0-0 and O 1 - 0 '(FIG. . 4).
The angular displacement of the transverse link 24 causes opposite displacements of the wheels of the left side by the same angular value, namely: the left rear wheel will rise and the left front wheel will lower. 7
Thus, angular fluctuations in the longitudinal and transverse planes are significantly reduced, which increases the comfort of the vehicle.

[1]
The invention relates to vehicle suspension and, in particular, to independent suspension of four-wheel vehicles. A four-wheeled vehicle suspension is known, comprising front and rear trailing arms connected to the wheels, transversely located torsions connected to said arms and a longitudinal link, the ends of which are hingedly attached to the vertical arms fixed on the torsion ll, Such a suspension design, due to the direct connection of the left and right wheels by common torsions, causes considerable angular oscillations in the vehicle movement both in the longitudinal and transverse planes. In addition, this design complicates the layout of the engine compartment, trunk, body floor and door openings, since the kinematic connection of the levers and rods forces them to provide the necessary cavities. The purpose of the invention is to increase comfortability of a transporting device by reducing its angular oscillations in the longitudinal and transverse planes. This goal is achieved in that the suspension is provided with additional longitudinal levers located under said longitudinal levers parallel to the latter, and with struts pivotally connected to the ends of the respective pairs of longitudinal levers, transversely located torsions made of two coaxially mounted parts, and the longitudinal trailing hectares and vertical stirs the levers are made of two parts, one another, while the ends of the parts of the torsions are rigidly connected to the parts of the vertical levers, the latter with the ends of the parts extending It is pivotally hinged, and parts of the rear-wheel vertical control arm are pivotally connected by a transverse thrust, the middle of which is hinged to the vehicle body through a longitudinal rod. In addition, parts of the longitudinal ti gi can be located in the cavity, made in the lower part of the vehicle body. The front wheels can be mounted on the uprights, and the rear wheels can be mounted on the shafts mounted in the stacks and connected through the transmission to the vehicle engine. FIG. 1 shows the proposed suspension, side view, and part of the body in FIG. 2 - axonometric image of the suspension; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 3. The suspension, mounted on housing 1, consists of trailing arms 2-5 and additional trailing arms 6-9, arranged parallel to those mentioned. The outer ends of the trailing arms 2–9 are pivotally connected to the uprights 10–13, on which the wheels are mounted, with the front ones being pivoted, and the rear ones - on the shafts connected via transmission to the vehicle engine. The inner ends of the longitudinal levers 2-5 are rigidly connected to transversely arranged torsions 14-17 made of two coaxially mounted parts, and the inner ends of the additional longitudinal levers 6-9 are pivotally connected to the housing 1. The inner ends of the torsions 14-17 are connected to the vertical .ry chagami 18t21, made of two parallel parts of one another; The lower ends of the said vertical arms are pivotally connected with a longitudinal thrust made of two parallel parts 22 and 23. The vertical levers 20 and 21 are pivotally connected by a transverse thrust 24, the middle of which is hinged to the vehicle body through the longitudinal rod 25. Torsions 14-17 are mounted in shells mounted in a housing through elastic supports 26, and connected to vertical levers 18-21 and to said shells by means of a slot (Fig. 3). The fastening of the transverse rod 24 to the vertical arms 20 and 21 and to the longitudinal rod 25 is shown in FIG. 3 and 4. The parts 22 and 23 of the longitudinal ton of gauge are located in the cavity 27, made in the lower part of the vehicle body (Fig. 1). The embossed structure provides a condition in which, for example, the right front wheel upward displacement causes the right rear wheel downward displacement, which, in turn, leads to an angular displacement of the transverse link 24 in the 0-0 position and about (fig. , four). The angular displacement of the transverse rod gi 24 causes opposing displacements of the left side wheels to the same angular value, namely: the left rear wheel rises, and the left front wheel descends. Thus, the angular oscillations in the longitudinal and transverse planes are significantly reduced, which increases the comfort of the vehicle. Claim 1. Suspension of a four-wheeled vehicle containing front and rear trailing arms connected to the wheels, transversely located torsyons connected to said arms, and a longitudinal link, the ends of which are pivotally connected to the vertical arms fixed on torsions, characterized in that, in order to increase the comfort of the vehicle by reducing its angular oscillations in the longitudinal and transverse planes, it is equipped with additional longitudinal arms, located under the said longitudinal arms parallel to the latter, and articulated with the ends of the respective pairs of trailing arms, the transversely located torsyons are made of two coaxially mounted parts, and the longitudinal arms and vertical levers are made of two parallel parts of one another, , while the ends of the brakes are connected to parts of the vertical levers — rigidly, the latter with the ends of the parts of the longitudinal arm are hinged, and parts of the vertical arm of the rear wheels are pivotally connected cross draft type, through which the middle longitudinal bar is hinged to the vehicle body.
