Description
Technical field
The utility model is related to automobile frame connected mode technical field, more particularly to a kind of fore sub frame and preceding lower swing arm
Attachment structure.
Background technology
The general attachment structure using double bushings during the parts design of fore sub frame and preceding lower swing arm, is passed through by bolt
Be fastened to preceding lower swing arm on subframe by bushing.It is attached with fore sub frame using the preceding lower swing arm of double bush structures, is passed through
Bolt, nut are fixed.Bushing is connected with fixed support by bolt, nut, and fixed support is to be welded on fore sub frame
On longeron, metal plate bulk strength is relatively low herein.Bushing sleeves do not allow to rotate during swing arm swings up and down, and it passes through bushing
The frictional force between gear hobbing and fixed support metal plate on end face carries out locking, and this kind of fit structure locking reliability is relatively low.Bushing
Fixed support is fixed by welding on front auxiliary car frame longitudinal beam, and welding structure causes this bushing fixing point precision relatively low.
Utility model content
For drawbacks described above of the prior art, it is high that the purpose of this utility model is to provide high intensity, locking reliability
The attachment structure of fore sub frame and preceding lower swing arm.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：Fore sub frame and preceding lower swing arm
Attachment structure includes fore sub frame, preceding lower swing arm.The bushing I of the preceding lower swing arm is connected by bolt III with fore sub frame, institute
The bushing II for stating preceding lower swing arm is connected by swing arm pivot pin with front frame.The swing arm pivot pin is made up of pivot pin and outer tube, axle
Pin two ends are provided with screw, and outer tube wraps up the pivot pin and is arranged on pivot pin middle part.Also include symmetrically arranged two locks
Only pad, described locking gasket one end is lock sleeve, and opposite side is provided with location hole.The lock sleeve of one locking gasket is set in
Pivot pin one end, bolt I is fixed on the fore sub frame through screw and location hole, and the lock sleeve of another locking gasket is arranged
In the pivot pin other end, bolt II is fixed on the fore sub frame through screw and location hole.
Further, the outer tube forms integrative-structure by the vulcanization of rubber with the pivot pin.
Further, the symmetric position for setting rubber in pivot pin is provided with position limiting structure.
The beneficial effects of the utility model, first, using the preceding lower swing arm of swing arm pin arrangement, fixed by double bolts,
Bush structure carries out locking (bushing inner sleeve is not rotated) low problem of reliability by frictional force in avoiding existing design.The
Two, subframe longitudinal beam uses integrated punching molding mode, swing arm pivot pin mount point hole size high precision；Inside subframe longitudinal beam
Reinforcing plate can be welded, is easy to improve intensity at swing arm pivot pin mount point, improve security.

Specific embodiment
Specific embodiment of the present utility model is described below in detail, is exemplary by reference to the embodiment of Description of Drawings
, it is only used for explaining the utility model, and can not be construed to limitation of the present utility model.
As Figure 1-3, the utility model fore sub frame includes fore sub frame 1 with the attachment structure of preceding lower swing arm, front lower
Swing arm 5, the bushing I 51 of preceding lower swing arm is connected by bolt III 7 with fore sub frame 1, and the bushing II 52 of preceding lower swing arm passes through swing arm
Pivot pin 3 is connected with front frame 1.Swing arm pivot pin 3 is made up of pivot pin 8 and outer tube 9, and the two ends of pivot pin 8 are provided with screw 12, outer tube
The 9 parcel pivot pins 8 are simultaneously arranged on the middle part of pivot pin 8.Also include symmetrically arranged two locking gaskets 6, the locking gasket 6
One end is lock sleeve 13, and opposite side is provided with location hole 14.One lock sleeve 13 of locking gasket 6 is set in the one end of pivot pin 8, bolt
I 2 are fixed on the fore sub frame 1 through screw 12 and location hole 14, and another lock sleeve of locking gasket 6 is set in pivot pin 8
The other end, bolt II 4 is fixed on fore sub frame 1 through screw 12 and location hole 14.Locking gasket passes through spiral shell with swing arm pivot pin
Bolt is fixed on fore sub frame, and locking gasket carries out spacing to swing arm pivot pin outer tube, plays safety protection function.
As shown in Fig. 2 outer tube 9 is vulcanized by rubber 10 forms integrative-structure with the pivot pin 8.In pivot pin 8, rubber is set
