Description
Technical Field
The utility model relates to a technical field of making an uproar falls in the automotive suspension system, concretely relates to leaf spring fixed end structure with function of making an uproar falls.
Background
Adopt metal pin axle to be connected between traditional leaf spring and the fixing support, it is gapped between round pin axle and leaf spring and the support, the suspension rubs and strikes and produces very big noise between the metal in the motion process, seriously influences passenger's travelling comfort and driving safety, and traditional structure needs regularly to maintain, and the round pin axle is also easy wearing and tearing.
SUMMERY OF THE UTILITY MODEL
To the problem that the background art exists, the utility model aims to provide a leaf spring fixed end structure who falls the function of making an uproar with low costs, change simply.
In order to achieve the above object, the utility model relates to a leaf spring fixed end structure with function of making an uproar is fallen, its characterized in that: the rubber bushing is accommodated between two vertical parts of the U-shaped part through a lug pin; the end part of one vertical part of the U-shaped parts is provided with a through hole, and the end part of the other vertical part is provided with a threaded hole; the lifting lug pin penetrates through the through hole and is in threaded connection with the threaded hole; the spring eye of the plate spring is sleeved on the rubber bushing.
Preferably, the inner walls of the two opposite vertical parts are provided with bosses, and the length of the rubber bushing is smaller than the distance between the top surfaces of the two bosses. Through such clearance fit, the installation is facilitated.
Preferably, a limiting bushing is arranged in the through hole, and the lifting lug pin penetrates through the bushing.
Further preferably, the limiting bush is in interference fit with the through hole.
Preferably, the vertical part provided with the through hole is also provided with a limiting hole, and the limiting hole is perpendicular to the through hole; the distance from the axis of the limiting hole to the axis of the through hole is greater than the radius of the limiting hole and smaller than the sum of the radius of the limiting hole and the radius of the limiting hole; and a limiting screw is arranged in the limiting hole, and a limiting groove matched with the limiting screw is arranged on the limiting bushing. Therefore, the limiting screw penetrates through the limiting hole and the limiting groove to limit the rotation of the limiting bushing, and the anti-loosening effect is achieved.
Preferably, the leaf spring eye is in interference fit with the rubber bushing.
Preferably, the rubber bushing comprises an outer steel sleeve and an inner steel sleeve, and rubber vulcanized between the outer steel sleeve and the inner steel sleeve. Thus, the rubber deformation plays a role in vibration and noise reduction.
Further preferably, the outer walls of the two ends of the inner steel sleeve are provided with limiting circular bosses. Thus, the retainer ring boss functions to increase roll stiffness when the vehicle rolls.
The utility model has the advantages that: the rubber bushing is of an assembly structure, is easy to replace, does not need to add butter, reduces the cost, improves the product quality, and is worthy of popularization.

Detailed Description
The technical solutions of the present invention (including the preferred ones) are described in further detail below by means of fig. 1 to 4 and enumerating some alternative embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 4, the utility model relates to a leaf spring fixed end structure with function of making an uproar falls, including fixing support 1, rubber bush 2, leaf spring eye 3, limit bush 4, lug pin 5 and stop screw 6.
The fixed support 1 is provided with a U-shaped part, and the rubber bushing 2 is accommodated between two vertical parts of the U-shaped part through a lifting lug pin 5; in this embodiment, one of the vertical portions is provided with a through hole 1.1, the other vertical portion is provided with a threaded hole 1.2 at the same axial position, a limiting hole 1.3 is formed in the vertical surface of the through hole 1.1, and bosses 1.4 are formed on two opposite inner sides of the fixing support 1.
Rubber bush 2 contains outer steel bushing 2.1 and interior steel bushing 2.2 and vulcanizes rubber 2.3 between the two, and the design of rubber bush both ends has spacing ring boss 2.4, rubber bush outer steel bushing 2.1 and 3 interference fit of leaf spring eye.
When the plate spring is installed, the inner steel sleeve 2.2 is installed between the boss 11.4 and the boss 21.5, the plate spring belongs to clearance fit, the limiting bush 4 is in transition fit with the through hole 1.1, the lug pin 5 is a special bolt and is matched and fastened with the threaded hole 1.2, and the limiting bush 4, the inner steel sleeve 2.2 and the boss 21.5 are tightly connected together through pressing force and friction force under the action of fastening force, so that the effect of transmitting force and moment is achieved.
