It elaborates below in conjunction with the accompanying drawings to specific embodiment of the utility model.It is to be appreciated that "upper",
The orientation or positional relationship of the instructions such as "lower", "front", "rear", "left", "right", " top ", " bottom end " is based on ... shown in the drawings
Orientation or positional relationship is merely for convenience of describing the present invention and simplifying the description, and does not indicate or imply the indicated dress
It sets or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to the utility model
Limitation.
As shown in Figure 1, a kind of damped suspension structure, including suspension 1 and mounting bracket 2.Mounting bracket 2 includes that suspension connects
Portion 3, bending section 4 and engine interconnecting piece 5, by the connection of bolt 6 suspension 1, engine interconnecting piece 5 is machined with suspension interconnecting piece 3
Mounting bracket is fixedly connected by bolt hole 7 for assembling bolt with engine.Suspend interconnecting piece 3 and engine interconnecting piece 5 it
Between the structure that is connected as a body seamlessly transitted by bending section 4, suspension interconnecting piece 3, bending section 4 and 5 one of engine interconnecting piece at
Type, on bending section 4 and 1 opposite curved surface 8 of suspension is equipped with rubber layer 9, and curved surface 8 and rubber layer 9 are bonded in one by bonding by Vulcanization
It rises.When automobile bumpy sections or hollow road conditions when driving, suspension metallic framework can collide with mounting bracket rubber layer 9,
Rubber layer plays cushioning effect, and abnormal sound caused by avoiding the direct collision between metal also reduces suspension and mounting bracket
The possibility of damaged in collision, improves service life of equipment.In order to ensure the reliability of 9 cushioning effect of rubber layer, rubber layer 9
Thickness is designed to be more than 1.5cm.
In order to reduce suspension to the shock frequency and shock dynamics of rubber layer, on the bending section and the suspension is opposite
It is additionally provided with Buffer Unit between curved surface 8 and suspension 1.As shown in Figures 2 and 3, the Buffer Unit include bearing 10, sliding rail 11,
Limited block 12, sliding block 13 and connecting rod 14, bearing 10 be fixed on suspension 1 outer surface, bearing 10 and suspension 1 shell one at
Type.Two sliding rails 11 parallel to each other are welded on bearing 10, one end of sliding rail 11 is fixedly connected with bearing 10, and the other end is welded with
Limited block 12, through-hole is machined on sliding block 13, and sliding rail 11 passes through 13 clearance fit of through-hole and sliding block of sliding block 13 so that sliding block 13
It can be slided along the extending direction of sliding rail.Be equipped with the first spring 15 between bearing 10 and sliding block 13, sliding block 13 and limited block 12 it
Between be equipped with second spring 16, the first spring 15 and second spring 16 surround on sliding rail 11.On bending section and the suspension is opposite
Curved surface 8 on set there are two link block 17, connecting rod 14 is equipped with two, and two connecting rods 14 are located at the both sides of sliding block 13, every
The equal one end of connecting rod is connected with link block 17 by axis pin, the side rotation connection of the other end and sliding block 13.
When automobile is travelled in bumpy sections or hollow road conditions, due to shock effect, between mounting bracket bending section 4 and suspension
Distance it is adjacent to each other when, power is transmitted to sliding block 13 by mounting bracket by connecting rod 14, and sliding block 13 is pushed to be slided along sliding rail 11, pressure
First spring 15 that contracts does work, and the first spring 15 plays cushioning effect, reduces shock dynamics of the suspension to rubber layer；Work as suspension
When the distance between bracket bent portion 4 and suspension increase, mounting bracket pulls sliding block 11 to compress second spring 16 by connecting rod 14
Acting, second spring 16 play cushioning effect, reduce active force of the mounting bracket to bolt 6, reduce the damage of bolt 6
Rate.
To further increase the cushion effect of Buffer Unit, the both ends of the first spring 15 are welded with bearing 10, sliding block 13 respectively
It is fixedly connected, the both ends of second spring 16 are welded and fixed connection with sliding block 13, limited block 12 respectively.Thus, when suspension branch
When the distance between frame bending section 4 and suspension are adjacent to each other, mounting bracket pushes sliding block 13 to slide by connecting rod 14, not only to press
First spring 15 that contracts does work, and to stretch the acting of second spring 16；Similarly, when between mounting bracket bending section 4 and suspension
Distance increase when, mounting bracket by connecting rod 14 pull sliding block 11 slide, not only to compress second spring 16 acting, Er Qieyao
Stretch the acting of the first spring 15.So that the maximum impact force that Buffer Unit described in the present embodiment can bear further increases.
Technical solution provided by the utility model is described in detail above, for the general technology people of this field
