Abstract
The utility model relates to a front control arm for an automobile. The front control arm for the automobile comprises a control arm body, a vertical casing and a horizontal casing, wherein the control arm body is of a multilayer structure and comprises an upper cover body and a lower cover body, the upper cover body and the lower cover body form a holding space, and a core body is arranged in the holding space; the vertical casing is arranged at one end of the control arm body; the horizontal casing is arranged at the other end of the control arm body; and a vertical inner hole and a horizontal inner hole are formed in the vertical casing and the horizontal casing respectively in a penetrating way, and corners of the vertical inner hole and the horizontal inner hole are circularly chamfered. Since the two ends of the inner holes of the front control arm for the automobile are circularly chamfered and are smoothly transitioned after chamfering, the situation of sharp corners is avoided, the situation that bush rubber is pulled damaged during press fitting of bushes in the inner holes is not caused, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to a kind of automobile-used front Control arm.
Background technology
Control arm is used in power actuated vehicle to help to support also each wheel of controlling machine motor vehicle.Usually, can find that Control arm is connected between the vehicle frame and wheel knob spare of power actuated vehicle, specifically is connected between vehicle frame and steering swivel.Due to many reasons applied pressure on the number of attaching parts and character and performance requirement and Control arm between Control arm and other vehicle part for example one by one, make the structure of Control arm totally complicated especially.
Control arm is a very crucial safety member of automotive suspension, works to connect steering swivel and subframe, control and is suspended in positional parameter, transmitted load in motion process, requires all very high to its Rigidity and strength.Simultaneously, the former endoporus of Control arm two ends are 2 * 45 ° of chamferings, and after chamfering, transition position produces wedge angle, can cause bushing rubber to pull phenomenon when causing endoporus to press-fit lining, affects the service life of product.
The utility model content
The utility model provide a kind of cheap for manufacturing cost, product strength is high, can guarantee to press-fit precision, the convenient automobile-used front Control arm of installing.
For solving the problems of the technologies described above, the automobile-used front Control arm of the utility model, comprise: the Control arm body, described Control arm body is multilayer architecture, described Control arm body comprises upper cover body and lower cover, described upper cover body and described lower cover form an accommodating space, are provided with core body in described accommodating space; Vertical pipes, described vertical pipes are arranged on an end of described Control arm body; Horizontal case, described horizontal case are arranged on an other end of described Control arm body; Be equipped with vertical endoporus and horizontal endoporus in described vertical pipes and described horizontal case, circular chamfering is adopted in the corner of described vertical endoporus and described horizontal endoporus.
Described upper cover body and described lower cover design for sectional type; Wherein said upper cover body comprises the first upper cover, the second upper cover that mutually connects successively; Described lower cover comprises the first lower cover, the second lower cover that mutually connects successively.Stagger mutually in the position of described the first upper cover and described the second upper cover and described the first lower cover and described the second lower cover.
The automobile-used front Control arm endoporus of the utility model two ends change circular chamfering into, and rounding off after chamfering does not have the wedge angle phenomenon, can not cause bushing rubber to pull phenomenon when endoporus press-fits lining, have improved the service life of product.Simultaneously, the automobile-used front Control arm left-right universal of the utility model has been saved mould, frock and production control expense, whole body construction concision and compact, and the arrangement space of having saved other parts of suspension reduces weight and manufacturing cost.

The specific embodiment
Below in conjunction with accompanying drawing, the automobile-used front Control arm of the utility model is described in further detail.
As shown in Figure 1, the automobile-used front Control arm of the utility model comprises: Control arm body, Control arm body are multilayer architecture, and the Control arm body comprises upper cover body and lower cover, and upper cover body and lower cover form an accommodating space, are provided with core body 5 in accommodating space; Vertical pipes 6, vertical pipes 6 are arranged on an end of Control arm body; Horizontal case 7, horizontal case 7 are arranged on an other end of Control arm body; Be equipped with vertical endoporus 8 and horizontal endoporus 9 in vertical pipes 6 and horizontal case 7, corner 10 places of vertical endoporus 8 and horizontal endoporus 9 adopt circular chamfering.
Upper cover body and lower cover design for sectional type; Wherein upper cover body comprises the first upper cover 1, the second upper cover 2 that mutually connects successively; Lower cover comprises the first lower cover 3, the second lower cover 4 that mutually connects successively.Stagger mutually in the position of the first upper cover 1 and the second upper cover 2 and the first lower cover 3 and the second lower cover 4.
The automobile-used front Control arm endoporus of the utility model two ends change circular chamfering into, and rounding off after chamfering does not have the wedge angle phenomenon, can not cause bushing rubber to pull phenomenon when endoporus press-fits lining, have improved the service life of product.Simultaneously, the automobile-used front Control arm left-right universal of the utility model has been saved mould, frock and production control expense, whole body construction concision and compact, and the arrangement space of having saved other parts of suspension reduces weight and manufacturing cost.
The preferred embodiment of below the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
