Abstract
Description
The present invention relates to a structure of a trailing arm, and more particularly, to a trailing vehicle which is capable of reducing the production cost and simplifying the number of parts by integrally forming the carrier, And the structure of ring rock.
In the field of automobiles, measures are being taken to integrate and simplify components in order to reduce costs and lighten the vehicle through modularization of components.
For example, front end modules, crash pad modules, suspension modules, and rolling chassis modules are being integrated. More specifically, parts are being integrated and simplified. Such a flow is also applied to a rear-wheel suspension structure of a vehicle.
BACKGROUND OF THE INVENTION [0002] In a passenger vehicle, a rear suspension is generally of a torsion beam axle type and a multi-link type.
Among these, the multi-link type has excellent adaptability to changes of alignment during bump and rebound of shock absorbers and springs, and has excellent ability to ground the road surface by keeping the wheel horizontally on the road surface.
A wheel coupled with a braking device (disc brake) 3 is mounted on a

Therefore, in order to reduce the cost and the weight of the vehicle, it is necessary to provide a structure in which the carrier and the trailing arm are integrally formed as a means of applying integration and simplification of parts.
Therefore, the present invention can be manufactured by a single step (e.g., press method) so that the carrier is integrally formed, thereby reducing the cost and simplifying the assembly of the vehicle body. The present invention is directed to providing a structure of a trailing arm capable of improving the performance of the trailing arm.
According to an aspect of the present invention, there is provided a structure of a trailing arm which is connected to a vehicle body at a front side thereof and a wheel coupled to a braking device at a rear side thereof to support a behavior of the wheel, A main plate having an arm part mounted with a bush and a carrier part extending rearwardly of the arm part and having a wheel mounted on its outer side; And a reinforcing member mounted on the carrier part for reinforcement of rigidity, wherein the main plate is formed integrally with the arm part and the carrier part.
Wherein the carrier part has a flat flat surface on which the reinforcing part is seated and a bent surface curved inward in an end direction of the flat surface, wherein the opposite surface of the side where the reinforcing part is seated on the flat surface and the flat surface are parallel .
In the present invention, a through hole is formed on the flat surface so that the axle is connected to the wheel, a second through hole is formed in the stiffener to be connected to the through hole, and a spindle plate is coupled to the outer surface of the carrier part, A bolt hole for bolting the bolt and a third through hole for connecting the through hole and the second through hole are formed in the spindle plate.
The upper part of the carrier part is provided with a space in which an upper arm is formed by bending a bending face so that the upper arm can be inserted and joined. The carrier part is formed in a shape with an open bottom under a flat surface, The lower end of the reinforcing member is formed in a constricted shape having a shorter length than the upper end so that the assisting arm enters between the bent surfaces of both sides and the reinforcing member to form a fastening space.
In addition, the arm part or the carrier part may be mounted with a bracket so that the stabilizer bar can be selectively fastened.
According to the present invention configured as described above, the carrier and the trailing arm can be integrally formed to reduce the cost, and the number of parts can be reduced, so that the assembling process can be shortened.
In the present invention, the stiffener includes a stiffener, and the stiffener is manufactured to have a predetermined size to increase the thickness of the carrier part, so that the rigidity can be efficiently reinforced.
In the present invention, mounting of the upper arm, the lower arm, and the assist arm is performed in a space formed between the bent surfaces (without passing through separate brackets) and a space between the bent surfaces and the reinforcing member, .
