Abstract
The invention relates to a vehicle front suspension control arm which comprises a control arm main body, wherein the control arm main body is provided with a connecting end with a steering knuckle, a front connecting end with a vehicle frame and a rear connecting end with the vehicle frame, a ball head pin assembly is fixed at the connecting end with the steering knuckle through a bolt, a ball head pin assembly is fixed at the front connecting end with the vehicle frame, and a hydraulic lining is fixed at the rear connecting end with the vehicle frame. The front suspension control arm can improve the cushioning effect of a vehicle, thereby improving the drivability and the comfort of vehicle driving.
Description
Technical field
The present invention relates to the front suspension system of automobile, be specifically related to the front suspension control arm in the front overhang frame system.
Background technology
Vehicle front suspension control arm belongs to the suspension guiding parts, is connecting wheel and vehicle body, plays power and the moment of transmitting wheel and vehicle body, guarantees the effect that wheel is beated with the relative vehicle body of certain movement track.
At present, in the structure of the front suspension system of most of vehicles, the connection of vehicle front suspension control arm and vehicle body and wheel is to adopt three end ways of connecting, and promptly an end of front suspension control arm is connected with wheel, other two ends and body contact.As shown in Figure 7, vehicle front suspension control arm comprises Control arm main body 6, have on the Control arm main body 6 with steering swivel (wheel place) coupling end G, with the preceding coupling end E of vehicle frame (vehicle body) and with vehicle frame after coupling end F, the edge between every two ends is provided with flange.On itself and steering swivel coupling end, ball end assembly 4 is arranged with bolt, before itself and vehicle frame coupling end E and with vehicle frame after all be fixed with rubber bush assembly 10 on the coupling end F, vehicle front suspension control arm is connected with steering swivel by ball end assembly 4, and connect to ground, thereby realize the connection of vehicle front suspension control arm and vehicle body and wheel by two rubber bush assemblies 10.
Vehicle front suspension control arm is by the rubber bush assembly and the body contact at its two ends, the vibration that causes for actv. control encourages from uneven road surface, wish that the rubber bush assembly has bigger damping, but, rubber bush assembly commonly used at present is difficult to provide needed big damping, thereby influences the road-holding property and the traveling comfort of vehicle '.And all adopt the rubber bush assembly to be connected before and after the front suspension control arm, under the prerequisite that guarantees vertical flexibility, can't improve the lateral rigidity of automobile front suspension effectively, thereby influence the stable operation performance of car load with vehicle frame.
Summary of the invention
The purpose of this invention is to provide a kind of vehicle front suspension control arm, with the damping effect of raising vehicle, thus the road-holding property and the traveling comfort of raising vehicle '.
Vehicle front suspension control arm of the present invention, comprise the Control arm main body, have on the Control arm main body with the steering swivel coupling end, with vehicle frame before coupling end and with vehicle frame after coupling end, on itself and steering swivel coupling end, the ball end assembly is arranged with bolt, edge between every two ends is provided with flange, the Control arm main body is fixed with the ball end assembly on the coupling end before itself and vehicle frame, be fixed with hydraulic bushing on the coupling end behind itself and vehicle frame.
The Control arm main body offers the flange hole on the coupling end before itself and vehicle frame, described ball end assembly is arranged in this flange hole and Control arm main body interference fit, thus make that the ball end assembly is fixed on the Control arm main body with vehicle frame before coupling end.
Coupling end is provided with hold down groove behind Control arm main body itself and the vehicle frame, and described hydraulic bushing is welded in this hold down groove by anchor shaft, thus make that hydraulic bushing is fixed on the Control arm main body with vehicle frame after coupling end.
The Control arm main body is provided with reinforced rib at the root of described edge flange, and reinforced rib is disappearing near near three ends of Control arm main body, and this reinforced rib can greatly strengthen the strength and stiffness of Control arm main body.
Hydraulic bushing is a prior art products, has the liquid storage cylinder of two independent symmetries in it, and is communicated with by the aperture fluid passage, utilizes the throttle characteristics of liquid stream in the aperture fluid passage to produce the liquid resistance.
When motor tire is subjected to road excitation and produces front and back when vibrating, the swing of drive front suspension control arm, thereby make fluid reservoir compression and expansion in the hydraulic bushing, hydraulic oil flows back and forth along the aperture runner and produces the damping of damped vibration, thereby has well improved the traveling comfort of vehicle '.
The front suspension control arm front end adopts the ball end assembly to be connected with vehicle body, not only be easy to install, improved the setting accuracy of front suspension control arm, and the more important thing is the great lateral rigidity that improves the front overhang frame system, cooperate the hydraulic bushing of front suspension control arm rear end and do not sacrifice vertical flexibility, thereby improved the stability of vehicle operating largely.
