Abstract
The utility model aims to provide a bracket of a trailing arm of a car, which is capable of effectively avoiding interference between the trailing arm and the bracket, and prolonging service lives of the bracket and the trailing arm. The bracket of the trailing arm of the car is characterized in that: a main body is a U-shaped bracket and includes left and right side walls, and an upper side wall which is connected with the left and right side walls; a front mounting hole and a rear mounting hole are formed on the upper side wall; an overturned side is formed on the edge of the upper side wall, wherein the front mounting hole and the rear mounting hole are formed on a boss of the upper side wall respectively; the plane of the boss is used as a mounting surface in connection with a car body; a technological lightening hole is formed on the rear part of the upper side wall; and a reinforcing rib is formed behind the front mounting hole on the front part of the upper side wall.
Description
Technical field
The utility model relates to automobile is pulled the support that arm is connected to auto body.
Background technology
The towing arm is safety member and a guide important in the car chassis system, and the towing arm support is a connection support important on the back axle, will pull arm and body contact through bolt and nut, is bearing the longitudinal loading in the running car.
Tradition towing arm support 1, as shown in Figure 1, the cross section is a U type structure; Rear lower forms opening 13, and is as shown in Figure 2, is convenient to pull arm 3 installations and motion; The plane 10 of upside utilizes three bolts hole 11,12,12 to be connected with vehicle body, and a circle forms flange 15 and gains in strength on every side.Towing arm support about 1 faces respectively have a coaxial through hole 14, through bolted connection the towing arm are installed, and are as shown in Figure 2.
The upper surface 10 of Control arm support in traditional design, promptly higher with the working accuracy of the attachment face of body contact, be convenient to installation surface and fit fully.In order to guarantee to pull the rigidity and the intensity of arm support 1; Then increase flange 15 height of a frame peripheral; Cause towing arm support 1 front and back assembly space to reduce, cause the motion space of towing arm 3 to reduce, therefore in the car load driving process; Can cause the interference problem of towing arm 3 and support 1, reduced towing arm 3 with and life-span of support 1.
The utility model content
The purpose of the utility model is to provide a kind of automobile towing arm support, and it can avoid pulling the interference of arm and support effectively, improves support and the service life of pulling arm.
For realizing the automobile towing arm support of said purpose; Its body is the U-shaped support; The upper side wall that has left and right sidewall and connect left and right sidewall is formed with preceding mounting hole, back mounting hole on the upper side wall, the edge of upper side wall is formed with flange; The characteristics of this automobile towing arm support are; Preceding mounting hole, back mounting hole are respectively on the boss of upper side wall, to form, the plane conduct of boss and the attachment face of body contact, and the rear that is formed with the preceding mounting hole of technology lightening hole and front portion at the rear portion of upper side wall is formed with reinforced rib.
Described automobile towing arm support, wherein, the reinforced rib left and right directions extends.
Described automobile towing arm support, wherein, reinforced rib is the groove that punching press forms on the upper side wall.
Preceding mounting hole, back mounting hole are respectively on the boss of upper side wall, to form; The plane conduct of boss and the attachment face of body contact, the rear that is formed with the preceding mounting hole of technology lightening hole and front portion at the rear portion of upper side wall is formed with reinforced rib, and boss has the effect that strengthens intensity; Reinforced rib also has the effect that strengthens intensity; Therefore can reduce the height of the flange at upper side wall edge, thereby the interference that can avoid pulling arm and support effectively improves support and the service life of pulling arm.

Fig. 2 is the back axle assembly block diagram that the towing arm support is installed.
Fig. 3 is the block diagram of towing arm support of an embodiment of the utility model.
The specific embodiment
As shown in Figure 3, the body of towing arm support 2 is the U-shaped support, in and arranged on left and right sides sidewall 26 is arranged, and the through hole 24 of coaxial line is arranged on the two side 26, so that through bolted connection towing arm (can understand with reference to Fig. 2).The towing arm is inserted between the two side 26 of U-shaped support.The edge of towing arm support upper side wall 20 is formed with flange 21, to strengthen intensity.Be formed with three mounting holes 23,22,22 on the towing arm support upper side wall 20, one of them is distributed in support front end (preceding mounting hole 23), and two are distributed in back-end support (back mounting hole 22) in addition.Orientation terms such as front, rear, left and right used herein are that the state when pulling arm and vehicle body with connection as shown in Figure 2 is reference.Preceding mounting hole 23 is formed on the boss 230.Back mounting hole 22 is formed on the boss 220.The height of each boss for example is 2.5mm, the plane conduct of boss 220 and the attachment face of body contact, the precision of assurance installation surface.Rear portion at the upper side wall 20 of support 2 is formed with technology lightening hole 25, reduces material cost.Rear anterior and preceding mounting hole 23 at the upper side wall 20 of support 2 is formed with reinforced rib 27; Reinforced rib 27 left and right directions extend; Improve support intensity and rigidity, and made the height of flange 21 of upper side wall 20 reduce, therefore increased the motion space of towing arm; On the whole, reduced the material that support uses.Because the minimizing of the height of flange 21, therefore the ability actv. has been avoided the interference of towing arm and support, has improved support and the service life of pulling arm.
