Description

[0001] The utility model relates to the field of transport engineering, in particular to the designs of vehicle suspension modules.

[0002] A known suspension module with a subframe assembly is an independent suspension system comprising a subframe assembly, upper and lower control arms, steering knuckles connecting the control arms to the wheel assemblies, and elastic elements. The subframe assembly consists of a lower subframe, upper control arms, upper control arm mounting plates, side plates connected to the mounting plates, and a crossmember located between the side plates. The upper ends of the elastic elements are connected to the cross beam of the subframe, and the lower ends are connected directly to the lower control arms (see patent EP 3241691 A1, IPC B60G11 / 27, B60G3 / 18, B60G3 / 20, B60G7 / 00, B62D21 / 11, published 08.11.2017).

[0003] The disadvantage of the known technical solution is the complexity of the design and the impossibility of using the suspension module with the subframe assembly for different vehicle modifications due to the impossibility of adjusting the position of the damper depending on the required dynamic characteristics of the vehicle.

[0004] The closest to the claimed technical solution in terms of the set of essential features is an independent suspension of a vehicle, comprising upper and lower double-arm U-shaped transverse levers, connected on one side to the steering knuckle of the wheel by means of spherical joints including a pin with a ball head, and on the other side connected by their arms to the upper and lower subframes by means of supports including axles with bushings, an elastic damping element. The upper end of the elastic damping element is secured to the frame bracket by means of a bearing and a conical axle, and the lower end is secured to the lower lever by means of a bearing and an axle installed in the corresponding holes and fixed from axial movement by means of a locking bar (see patent RU153661, IPC B60G3 / 20, published on 24.12.2014).

[0005] The disadvantage of the known technical solution is the impossibility of using independent vehicle suspension for different vehicle modifications, due to the impossibility of adjusting the position of the elastic damping element depending on the required dynamic characteristics of the vehicle.

[0006] The technical problem that the claimed technical solution is aimed at solving is to ensure the unification of the vehicle suspension module for different vehicle modifications, through the use of standard elastic damping elements, upper and lower levers.

[0007] The technical result consists in ensuring the unification of the vehicle suspension module, and is achieved due to the fact that in the vehicle suspension module, containing a subframe with upper and lower transverse levers installed thereon, elastic damping elements, the lower ends of which are connected to the lower levers, the elastic damping elements are connected to the lower levers through spacer elements.

[0008] A new feature is the connection of the elastic damping elements to the lower arms through spacer elements.

[0009] Connecting the elastic damping elements to the lower control arms via spacers, in conjunction with the features of the limiting part of the formula, made it possible, by using spacers of varying lengths and thicknesses, to maintain the upper attachment point of the elastic damping elements to the subframe bracket. Using standard-length elastic damping elements and standard-design lower control arms, the lower attachment point of the elastic damping elements can be varied. This allows for the positioning of the elastic damping elements to be adjusted depending on the required dynamic characteristics of different vehicle models. This, in turn, ensures the unification of the vehicle suspension module and, consequently, improves its performance. Furthermore, unification of the vehicle suspension module yields an additional technical benefit, namely, increased reliability due to the creation of a single suspension module.

[0010] The claimed utility model is illustrated by drawings:

[0011] Fig. 1 - vehicle suspension module, general front view in ¾ angle;

[0012] Fig. 2 - the same, general view from behind at a ¾ angle;

[0013] Fig. 3 - the same, general view from below at ¾ angle.

[0014] The vehicle suspension module comprises a subframe 1 with upper and lower transverse levers 2 and 3, respectively, and elastic damping elements 4 mounted on it.

[0015] Subframe 1 consists of longitudinal elements 5 connected to each other by means of transverse elements 6 and 7. In the middle and lower parts of the longitudinal elements 5, places are made for fastening the free ends of the upper and lower transverse arms 2 and 3, respectively. The fastening places of the upper and lower transverse arms 2 and 3 are reinforced by plates 8 and 9, which strengthen the fastening points of the upper and lower transverse arms 2 and 3. Transverse elements 7 and plates 8 and 9 additionally ensure a decrease in the mobility of the upper and lower transverse arms 2 and 3 under loads. In the upper part, brackets 10 are permanently attached to the outer surfaces of the longitudinal elements 5, in the upper part of which a place is made for fastening the upper end of the elastic damping elements 4. To strengthen the structure, the lower surface of the subframe 1 is reinforced by an additional lower plate 11, detachably connected to the lower transverse elements 6.Also on the subframe 1 there are places for fastening the main transmission gearbox, steering elements and other vehicle components (not shown).

[0016] The upper and lower transverse levers 2 and 3 are made of a single Y-shape, the free ends of which are pivotally connected to the longitudinal elements 5 of the subframe 1, and the tops are intended for connection with the steering knuckle (not shown). On the upper surface of the lower transverse levers 3, a place is made for fastening the lower end of the elastic damping elements 4. The elastic damping elements 4 are pivotally connected with the upper ends to the brackets 10 of the subframe 1, and with the lower ends they are pivotally connected to the lower transverse levers 3 through the spacer elements 12. The spacer elements 12 can be made of different lengths and thicknesses, and are detachably connected to the lower transverse levers 3. This design of the spacer elements 12 makes it possible to install the elastic damping elements 4 at different angles and positions depending on the required dynamic characteristics. The elastic damping elements 4 can be made in the form of spring struts or hydropneumatic cylinders.

[0017] The design of subframe 1 allows for the vehicle suspension module to be assembled in a dedicated workstation, ensuring high-quality assembly with minimal labor costs and increasing reliability. Subframe 1 of the suspension module is then attached to the vehicle frame side members using fasteners.

[0018] This design of the suspension module makes it possible to use elastic damping elements 4 of standard length and lower arms 3 of standard design for different vehicle modifications and to change the position of the elastic damping elements 4 depending on the required dynamic characteristics of different vehicle modifications by using spacer elements 12 of different lengths and thicknesses.

[0019] The claimed utility model has made it possible to ensure the unification of the vehicle suspension module.

[0020] The claimed vehicle suspension module can be manufactured using standard technological equipment using known materials and technologies.
