Description
Technical field
The invention belongs to the installation accessory of automobile manufacturing field, more particularly to rear axle towing arm and its support.
Background technology
Field is manufactured in automobile production, multi link formula independent suspension structure is used as a kind of common hind axle assembly version
In being applied to automobile product.The hind axle assembly of multi link formula independent suspension structure mainly by Rear secondary frame for vehicle, control arm, towing arm and
Its mounting bracket etc. is constituted.During automobile hind axle assembly and vehicle body are attached together, hind axle assembly front end is by pulling arm assembly
It is attached with vehicle body.
As shown in figure 1, towing arm assembly 10 includes the bracket of trailing arm 12 of the towing arm 11 of connection rear axle and connection vehicle body,
Installing hole 111 is wherein offered on the front end of towing arm 11, is connected using nut between hind axle assembly and the installing hole.Towing arm
Nut connection is also adopted by between 11 rear end and bracket of trailing arm 12, is used to connect the mounting surface of vehicle body on bracket of trailing arm 12
121 are provided with multiple connecting holes 122.On car load, the mounting surface 121 of bracket of trailing arm 12 needs to abut in body bottom, and
It is bolted on vehicle body.Due to there is difference in height between body bottom and rear axle, then towing arm 11 is inclined and is connected to
Between body bottom and rear axle, that is to say, that have angle between the mounting surface 121 of towing arm 11 and bracket of trailing arm 12, the folder
Towing arm 11 and the assembling angle of bracket of trailing arm 12 that angle is just known as.If the assembling angle exists larger with theoretical angle
Error, will misplace between the installing hole on connecting hole 122 and vehicle body on bracket of trailing arm 12, cause pull arm assembly without
Method is assembled.If assembling angular displacement very little, naked eyes can not recognize, even if can install reluctantly, will also result in towing arm and bear torsion
Power.Because towing arm 11 is provided with cushion 13, the torsion that towing arm is born is concentrated at the most weak cushion 13 of intensity, easily
Cause pulling, damaging for cushion.Therefore, there is strict technological requirement to the angle of assembling of towing arm and its support.But, mesh
Front towing arm is the angle that towing arm and its mounting bracket are controlled by installer's visual observations when installing with its support, this
Mounting means is planted it is difficult to ensure that assembling the accuracy at angle between towing arm and its mounting bracket, the quality of product is had a strong impact on.
The content of the invention
It is an object of the invention to provide a kind of installation accessory for guaranteeing rear axle towing arm and its support installation accuracy.
For achieving the above object, present invention employs technical scheme below：A kind of installation of rear axle towing arm and its support
Accessory, including bracket and the bracing frame for support support towing arm for support support bracket of trailing arm, between bracket and bracing frame
Distance is coincide with the brachium of towing arm, and described bracket is provided with the cavity for accommodating bracket of trailing arm, and the upper surface of cavity is used for
The mounting surface of support support bracket of trailing arm, described upper surface is horizontally disposed with, and support frame as described above is provided with for support support towing arm
Draw-in groove, the draw-in groove it is opening up, the bottom land of draw-in groove is in tilted layout from top to bottom, the angle between bottom land and upper surface with towing
Assembling angle between arm and bracket of trailing arm coincide.
Due to using above technical scheme：Towing arm is placed in draw-in groove, and the angle of inclination of draw-in groove bottom land determines towing
The angle of inclination of arm, then bracket of trailing arm is placed in cavity, it is ensured that the mounting surface of bracket of trailing arm abuts in horizontally disposed
Upper surface on.Now, one end of towing arm connection bracket of trailing arm overhangs in cavity, due to towing arm and its phase of support
Accessory has been mounted to position to fix, so need not adjust the angle between towing arm and its support when installing, directly used
Bolt and nut tightens the assembling that can just realize pulling arm assembly, it is ensured that operating efficiency is improve while installation accuracy.
