Abstract
The utility model relates to an integral type lower control arm for an independent pneumatic suspension. The integral type lower control arm for the independent pneumatic suspension comprises a lower control arm body. One end of the lower control arm body is provide with a pair of hinged pin hole seats hinged with an air bag bearing seat. The other end of the lower control arm body is provided with a pair of hinged pin hole seats hinged with a vehicle frame. The lower control arm body is in an enclosed isosceles trapezoid structure. The cross section of each side of the isosceles trapezoid is T-shaped. T-shaped pectoral plates of the two waist sides and the large bottom side face a space defined by each side of the isosceles trapezoid. A T-shaped pectoral plate of the small side faces a side hinged with the air bag bearing seat. The T-shaped pectoral plate of the small side are combined with a reinforce rib arranged at the lower end of the hinged pin holes of the air bag bearing seat as a whole. The integral type lower control arm for the independent pneumatic suspension has the advantages that integral cast structure is adopted, local structure is strengthened, processing technology is simplified, coaxiality of an axis of the hinged pin hole seats at the same end of the lower control arm is guaranteed, parallelism of the axis of the hinged hole seats at two ends of the lower control arm is guaranteed and deformation is not prone to occur.
Description
Technical field
The utility model relates to a kind of suspension device for vehicle, more specifically to a kind of integral type Lower control arm for independent air suspension.
Background technology
In free-standing airsuspension system, the up/down Control arm is the critical component in the suspension system, and on the one hand, it transmits force and moment between vehicle frame, and on the other hand, its arrangement form and size have determined the motion characteristics of suspension system.In this system, up/down Control arm one end is by rubber sphere hinge and vehicle frame, and subframe or vehicle body are articulated and connected, and the other end is articulated and connected by bearing pin and air bag load bearing seat.Therefore, for guaranteeing that automobile has good stability, ride comfort in the process of moving, require that the up/down Control arm possesses not only that bearing capacity is strong, good rigidly, the good technical index such as indeformable, and in other index, as: easily processing, saving cost also are that enterprise produces an aspect must considering.Existing up/down Control arm is mostly from bearing capacity employing welded structure, the weak point of the up/down Control arm of this welded structure is, parts are many, processed complex, the defective that welding quality exist to be hidden is though also be difficult to guarantee the right alignment of the hinge pin hole seat axis of the same end of up/down Control arm, also be difficult to guarantee the parallelism of the hinge pin hole seat axis at up/down Control arm two ends through techniques such as heat treatments.
Summary of the invention
The purpose of this utility model be a kind of processing rational in infrastructure, easy is provided for the prior art weak point, indeformable, with low cost, product quality is high is used for the integral type Lower control arm of independent air suspension.
The purpose of this utility model is to realize by following measures: a kind of integral type Lower control arm for independent air suspension, include the Lower control arm body, one end of Lower control arm body is provided with a pair of hinge pin hole seat that is articulated and connected with the air bag load bearing seat, the other end of Lower control arm body is provided with a pair of hinge pin hole seat that is articulated and connected with vehicle frame, its special character is, described Lower control arm body is the isosceles trapezoid enclosed construction, each cross section, limit of isosceles trapezoid is T-shaped, the T shape web on two waists and large base is in the space that each limit of isosceles trapezoid surrounds, the T shape web on little base is towards a side that is articulated and connected with the air bag load bearing seat, described little base T shape web be connected with the strengthening rib that seat lower end, air bag load bearing seat hinge pin hole arranges.
Compared with prior art, adopted the integral type Lower control arm that is used for independent air suspension that the utility model proposes, have following advantage: this product adopts the integral type cast structure, local structure are strengthened, simplified processing technology, simultaneously, guarantee the hinge pin hole seat axis of the same end of Lower control arm right alignment, guarantee the parallelism of the hinge pin hole seat axis at Lower control arm two ends, not yielding, improved stability, the ride comfort of running car.
Description of drawings:
Fig. 1 is an embodiment schematic diagram that the utility model proposes.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated: Fig. 1 provides an embodiment of the present utility model.Among the figure, a kind of integral type Lower control arm for independent air suspension includes: an end of Lower control arm body 3, Lower control arm body 3 is provided with a pair of hinge pin hole seat 1 that is articulated and connected with the air bag load bearing seat, the other end of Lower control arm body 3 is provided with a pair of hinge pin hole seat 2 that is articulated and connected with vehicle frame.Described Lower control arm body 3 is the isosceles trapezoid enclosed construction, each cross section, limit of isosceles trapezoid is T-shaped, the T shape web on two waists and large base in the space that each limit of isosceles trapezoid surrounds, the T shape web on little base is towards a side that is articulated and connected with the air bag load bearing seat, described little base T shape web 31 be connected with the strengthening rib 32 that seat 1 lower end, air bag load bearing seat hinge pin hole arranges.
Above-described embodiment does not consist of restriction of the present utility model, and all employings are equal to replaces or technical scheme that the form of equivalent transformation obtains, all drops within the protection domain of the present utility model.
