Abstract
The utility model discloses a lower suspension arm of an automobile, which solves the problem that the damping effect of the rear bushing on the conventional lower suspension arm of an automobile is weak. The lower suspension arm provided by the utility model comprises the lower suspension arm and a round rear bushing; the center of the rear bushing is positioned on the axis of the cylinder-shaped connecting sleeve of the lower suspension arm; the rear bushing comprises a metal outer sleeve, a rubber middle sleeve and a metal inner sleeve which are in sleeve joint in sequence; the metal outer sleeve and the lower suspension arm are connected to be a whole; a pair of grooves which are symmetric about the axis of the bushing are formed on the outer ring of the rubber middle sleeve; and the line of centers of the two grooves and the axis of the cylinder-shaped connecting sleeve intersect with each other to form an included angle. The utility model improves the damping effect of the rear bushing on the lower suspension arm, and remarkably reduces influences of wheels on a steering system.
Description
Technical field
The utility model relates to a kind of auto parts and components, swing arm under particularly a kind of automobile.
Background technology
Vehicle in the process of moving, because it is ground-surface uneven, to cause the vibration of wheel, vibration can be delivered on the subframe by following swing arm again, causes the subframe vibration, and then causes the steering swivel system vibration that is connected on the subframe, cause the bearing circle shake, rubber coating in the following swing arm back bush then can play damping of vibrations, but the rubber damping effect of installing in the swing arm back bush under the existing vehicle is faint, can't play the better damping effect.
Chinese patent notification number CN2931227Y, August 8 2007 day for announcing, announced a kind of structure improved swing arm lining, it comprises columnar sleeve pipe, rubber coating and lining, rubber coating is placed on the sleeve pipe, lining is placed in the rubber coating outside, the outside, middle part of sleeve pipe has convex shoulder, the inboard of rubber coating has the shape that matches with above-mentioned convex shoulder, it is low that this patent has solved swing arm lining stability in use, the problem that service life is short, but the not mentioned shockproof structure of this swing arm lining still can't play the better damping effect during use.
Summary of the invention
The purpose of this utility model is to solve the faint problem of swing arm back bush effectiveness in vibration suppression under the existing vehicle, provides a kind of to swing arm under the tangible automobile of vibration damping effect.
The technical scheme that its technical matters that solves the utility model adopts is: swing arm under a kind of automobile, comprise swing arm down and circular back bush, the center of back bush is positioned on the axis of following swing arm cylindrical shape adapter sleeve, back bush comprises metal-coating, cover and inner metal sleeve in the rubber, cover and inner metal sleeve socket successively in metal-coating, the rubber, metal-coating is connected as a single entity with following swing arm, the outer shroud that overlaps in the described rubber is provided with a pair of groove about lining axis symmetry, and the line of centres of two grooves and the axes intersect of cylindrical shape adapter sleeve form angle.In following swing arm, play main damping of vibrations and be in the rubber on the back bush and overlap, cover adopts the rubber after sulfuration process is processed to make in the rubber, can increase the elasticity of rubber, increase the service life, the groove of symmetry is opened on the outer shroud that overlaps in the annular rubber, help overlapping in the rubber vibration that absorbs from wheel, produce elastic deformation then and discharge, thereby play damping of vibrations, be enclosed within the damping of vibrations that cover plays in the rubber that influences that position in the back bush can be bigger in the rubber, when the installation site of overlapping in the rubber is incorrect, the effectiveness in vibration suppression that plays is faint, therefore the line of centres of two grooves forms angle with the axes intersect of cylindrical shape adapter sleeve, and this angle helps determining to be enclosed within the rubber installation site in the back bush, makes to overlap in the rubber to be in preferable position, absorb vibration better, obviously improve effectiveness in vibration suppression from wheel.
As preferably, described angle is 20 to 40 degree.Through experimental test, angle overlaps in the rubber in this angular range can play the better damping effect, helps reducing the influence that unsteadiness of wheels brings to steering swivel system.
As preferably, angle is 28 degree.Through experimental test, angle overlaps the effectiveness in vibration suppression effect that plays in this angle rubber best, compares with existing swing arm back bush down and significantly improved effectiveness in vibration suppression, improved 26 percent on the directions X, improved 20 percent on the Y direction, improved 5 percent on the Z direction.
As preferably, the bottom portion of groove that puts in the rubber is the convex shoulder shape, and the cross-sectional plane of convex shoulder is circular arc.The part that puts the convex shoulder shape in the rubber makes that cover has two ring-shaped depressions up and down in the rubber, is beneficial to cover in the rubber and absorbs vibration from wheel, strengthens effectiveness in vibration suppression.
The beneficial effects of the utility model are: the setting of cover outer ring upper groove in the rubber, improved the effectiveness in vibration suppression of overlapping in the rubber, be beneficial to and overlap the vibration of alleviating from wheel in the rubber, the axes intersect of the line of centres of two grooves and cylindrical shape adapter sleeve forms angle, such setting, make that cover is positioned at best vibration damping position in the rubber, can further improve effectiveness in vibration suppression, significantly reduce the influence of unsteadiness of wheels steering swivel system.
Description of drawings
Fig. 1 is the utility model master TV structure scheme drawing.
Among the figure: 1, down swing arm, 2, front lining, 3, the cylindrical shape adapter sleeve, 4, back bush, 41, metal-coating, 42, overlap in the rubber, 43, inner metal sleeve, 5, angle, 6, groove.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
Swing arm under a kind of automobile (referring to accompanying drawing 1), comprise swing arm 1 down, following swing arm 1 is the isoceles triangle shape, the upper right side of following swing arm 1 has front lining 2 by bolt, the left upper end of following swing arm 1 is welded with cylindrical shape adapter sleeve 3, the lower-left end of following swing arm 1 is circular back bush 4, the center of back bush 4 is positioned on the axis of cylindrical shape adapter sleeve 3 vertical directions, back bush 4 is connected as a single entity with following swing arm 1, back bush 4 comprises metal-coating 41, cover 42 and inner metal sleeve 43 in the rubber, cover 42 is placed in inner metal sleeve 43 outsides in the rubber, metal-coating 41 is placed in cover 42 outsides in the rubber, metal-coating 41, cover 42 and inner metal sleeve 43 threes are fixed together in the rubber, metal-coating 41, cover 42 and inner metal sleeve 43 threes are coaxial in the rubber, the interior ring of metal-coating 41 is circular, inner metal sleeve 43 is an annular arrangement, cover 42 forms for a pair of groove 6 of processing on the outer shroud of annular rubber cover in the rubber, two grooves 6 are about the axis symmetry of back bush 4, groove 6 bottoms are the arc of convex shoulder shape, the axes intersect of the line of centres of two grooves 6 and cylindrical shape adapter sleeve 3 vertical directions is in the center of back bush 4, and forming angle 5, angle 5 is 20 octaves.
When the transfer of vibration of wheel is extremely descended swing arm 1, groove 6 places of cover 42 produce elastic deformation in the rubber on the back bush 4, and be compressed, groove 6 places of cover 42 discharge elastic deformation in the rubber then, restore to the original state, the vibration that the wheel transmission comes is absorbed, thereby is converted into elastic deformation and is released, and reaches the purpose of vibration damping.
