Abstract

The utility model provides an automobile swing arm assembly. The automobile swing arm assembly comprises a swing arm body with three connecting arms. The free ends of the connecting arms are connected with supporting pieces, and a through hole is formed in the middle of the swing arm body. The automobile swing arm assembly is characterized in that a groove is formed in the inner side wall of the through hole, and an annular reinforcing strip is embedded in the groove. By the arrangement of the annular reinforcing strip embedded in the through hole, radial supporting force is provided for the through hole, therefore, the intensity of the middle of the swing arm body is increased, and the whole intensity performance of a swing arm is improved.

Description

A kind of automobile swing arm assembly
Technical field
The utility model belongs to the auto parts and components field, is specifically related to a kind of automobile swing arm assembly.
Background technology
Suspension is the general name of vehicle frame and all the power transmission connecting devices between vehicle bridge or the wheel of automobile, its effect is that power and the power of transfer function between wheel and vehicle frame is turned round, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, and the vibrations that decay and cause thus, to guarantee that automobile can smoothly travel.
Typical suspension structure is comprised of elastic element, guiding mechanism and bumper etc., and discrete structure then also has bump rubber, Panhard rod etc.Elastic element has again the forms such as steel spring, air bellow, coil spring and torsion bar spring, and the Modern Car suspension adopts coil spring and torsion bar spring more, and indivedual luxury cars then use air bellow.Suspension is an important composition in the automobile, and it flexibly connects vehicle frame and wheel, is related to the multiple in-use performance of automobile.Exteriorly, the sedan suspension system only is comprised of some bars, cylinder and spring, but must not think that it is very simple, opposite car suspension is difficult automobile assembly that reaches perfect requirement, this is because suspension should satisfy the traveling comfort requirement of automobile, satisfy again the requirement of its road-holding property, and this two aspect is in opposition to each other.
Swing arm is the critical component in the automobile suspension system, for make swing arm lightweight, intensity is high, cost is low, the partial cross-section of present most swing arms all is " recessed " shape.But this mode meeting is so that the bulk strength decline of swing arm.
The utility model content
The utility model provides a kind of automobile swing arm assembly that can effectively strengthen bulk strength for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of automobile swing arm assembly comprises the swing arm body with three connecting arms, and the free end of described connecting arm links to each other with strut member, is provided with a through hole at the middle part of swing arm body;
It is characterized in that, be provided with groove on the madial wall of described through hole, described groove has been embedded in annular strap stiffener.
Further setting of the present utility model is, described groove is two, and two grooves are separately positioned on the upper and lower edge of through hole.
Further setting of the present utility model is, three free ends of described three connecting arms are respectively arranged with Large lining, little lining and ball end assembly.
Further setting of the present utility model is, described three connecting arms are structure as a whole.
Automobile swing arm assembly described in the utility model is embedded into annular strap stiffener in the through hole by setting, for through hole provides radial support power, thereby so that the intensity at swing arm body middle part is increased, has improved the strength character of swing arm integral body.
Description of drawings
Fig. 1 is the constructional drawing of swing arm assembly described in the utility model.
The specific embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of automobile swing arm assembly, comprises the swing arm body with three connecting arms, and described three connecting arms are structure as a whole; The free end that the free end that the free end of the first connecting arm 1 is provided with Large lining 4, the second connecting arms 2 is provided with little lining 5, the three connecting arms 3 is provided with ball end assembly 6.Be provided with a through hole 7 at the middle part of swing arm body, be provided with groove on the madial wall of described through hole 7, described groove has been embedded in annular strap stiffener 8.Described groove can be two, and two grooves are separately positioned on the upper and lower edge of through hole 7.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
