Abstract
The invention discloses an automobile rear suspension bushing which comprises an outer bushing pipe and an inner bushing pipe, wherein the outer bushing pipe and the inner bushing pipe are vulcanized into a whole. The bushing is connected with an automobile body through bolts and nuts, bosses are symmetrically arranged on the outer cylindrical faces of the bolts in the radial direction, and grooves matched with the bosses are formed in the inner bushing pipe and automobile body bolt holes. The automobile rear suspension bushing is simple in machining technology, easy to achieve and capable of preventing the bushing from rotating relative to the automobile body, enables the connecting portion of the bushing and the automobile body to be more reliable and to be prevented from loosening, ensures bushing working reliability of the connecting portion, and prevents abnormal sounds.
Description
Technical field
The present invention relates to technical field of vehicle manufacture, be specifically related to a kind of rear overhang rack lining.
Background technique
Along with expanding economy, the raising of people's living standard, automobile has become the essential traffic instrument of people's trip.But automobile is in order to obtain better NVH performance, increasing passenger car rear suspension adopts the suspension frame structure of many linkage types.In order to relax the impact to rod member and vehicle body connection part, the connection of rod member and vehicle body generally adopts rubber bushing to be then connected with bolt.As shown in Figure 1, between lining 1 and vehicle body 2, connect with bolt 3, because the other end of rod member is connected with wheel drag, so lining end rotates the axis around bolt in the time of wheel hop.But in order to allow the rubber bushing of sulfuration in lining inner tube play a role, automobile suspension system design expects that lining inner tube and vehicle body do not have rotation and occur, lining inner tube 4 is relative with vehicle body 2 static.
Prior art existing problems:
As shown in Figure 1, in order to make lining inner tube 4 relative with vehicle body 2 static.By lining inner tube and vehicle body cover enough large pressure (some lining inner tube adopts toothed surface to increase compressive load per unit area) prevent that lining inner tube from rotating relative to vehicle body.The mode of obtaining larger pressure is to make bolt pretightening reach high value.But when automobile increases service time, bolt pretightening reduces, and the pressure of this lining inner tube and vehicle body junction plane reduces, and just has the relative vehicle body cover of inner tube risk in relative rotation.Once relatively rotate, rubber bushing lost efficacy, and can produce abnormal sound simultaneously.
In sum, to be connected with vehicle body be not very reliable to existing lining.
Summary of the invention
Be connected for solving existing lining the problem easily rotating with vehicle body, the invention provides a kind of rear overhang rack lining, can make lining relative with vehicle body fixing, effectively prevent from rotating, becoming flexible.
Technological scheme of the present invention is:
A kind of rear overhang rack lining, comprise lining outer tube and the lining inner tube that sulfuration is integrated with it, between lining and vehicle body, connect with bolt and nut, on the external cylindrical surface of bolt, radial symmetric is provided with boss, on lining inner tube and carriage bolt hole, is respectively arranged with the groove matching with described boss.
Described boss is two; The size of described boss is less than the size of described groove.
In described lining inner tube, the position of two grooves is corresponding one by one with the position of two grooves in carriage bolt hole; Described groove is square groove.
Beneficial effect of the present invention: rear overhang rack lining of the present invention, processing technology is simple, easily realizes, and can effectively prevent that lining from rotating relative to vehicle body, can make lining and vehicle body attachment portion more reliable, prevent from becoming flexible, ensure the reliability of coupling part lining work, and prevent abnormal sound.

Embodiment
With reference to Fig. 8, rear overhang rack lining of the present invention, comprises lining outer tube 1 and the lining inner tube 4 that sulfuration is integrated with it, between described lining and vehicle body 2, connects with bolt 3 and nut 5.
With reference to Fig. 2,3,4 and 6, on the external cylindrical surface contacting with lining inner tube 4 and vehicle body 2 at described bolt 3, radial symmetric is provided with two boss 31, and the end machining of described bolt 3 has screw thread.The bolt hole of lining inner tube 4 and vehicle body 2 is respectively arranged with the square groove 41 and 21 matching with described boss, and for placing described boss 31, the size of described boss 31 is less than the size of described groove 21 and 41.The position of interior two grooves 41 of lining inner tube 4 is corresponding one by one with the position of two grooves 21 in the bolt hole of vehicle body 2.
With reference to accompanying drawing 5, when described lining is connected with vehicle body 2, the groove of lining inner tube 4 41 is alignd with the groove 21 of vehicle body, then put into the bolt 3 with boss 31, boss 31 is limited in the groove 21 and 41 of vehicle body 2 and lining inner tube 4.Then tight a bolt 3.Lining inner tube 4 is fixed by relative with vehicle body 2 like this.
When work, lining outer tube 1 rotates relative to lining inner tube 4, and this lining effectively plays a role.Lining inner tube 4 relative vehicle bodies 2 also maintain static simultaneously, and reliable in structure, there will not be loosening risk, prevent that abnormal sound and lining lost efficacy.
Claims (5)
1. a rear overhang rack lining, comprise lining outer tube and the lining inner tube that sulfuration is integrated with it, between lining and vehicle body, connect with bolt and nut, it is characterized in that, on the external cylindrical surface of bolt, radial symmetric is provided with boss, on lining inner tube and carriage bolt hole, is respectively arranged with the groove matching with described boss.
2. rear overhang rack lining according to claim 1, is characterized in that, described boss is two.
