Abstract

PURPOSE:To aim at reduction in link length and improvement in the lowest road clearance, by forming an extension part, projecting more ahead than a body side pivoting part, in the front end side of a trailing arm, while connecting a piece among plural lateral links to this extension part. CONSTITUTION:A rear suspension consists of a trailing arm 1, being pivotally attached to a car body at the front end side and set up in a longitudinal direction of the car body under supporting a wheel 16 on the rear end side in free of rotation, and plural lateral links 21-41 to be set up loterally of the car body. In the case above mentioned an extension part 5 projecting more ahead than a body pivoting part E is formed in the front end side of the arm 1, and a piece among these lateral links 21-41, for example, the first lateral link 21 is connected to this extension part 5. With this constitution, the first lateral link 21 comes nearer to the pivoting point E so that the link length is reducible.

に第１ラテラルリンクを連結したことが開示される。If the three lateral links are called the first to third lateral links from the front, the second and third lateral links are connected to the rear of the trailing arm, while the first lateral link is connected to the rear of the trailing arm. The connection between the front and rear intermediate portions is disclosed in JP-A-80-53408 and US Pat. No. 3,327-803, and also in JP-A-57-110.
No. 513 discloses that a first lateral link is connected below the vehicle body side pivot portion of the trailing arm.

ない。(Problem to be Solved by the Invention) However, when the first lateral link is connected to the intermediate portion of the trailing arm as in the former case, this connection point extends far rearward from the pivot point on the vehicle body side at the front end of the trailing arm. Since they are separated, the first lateral link must be made long to ensure vertical swing of the trailing arm.

Multiple lateral links (21) arranged in the lateral direction of the vehicle body
, (31), and (41), an extension part (5) is formed on the front end side of the trailing arm (1) and projects forward from the vehicle body side pivot part (E). In part (5), the plurality of lateral links (21
), (31), and (41) are connected.

る。(Function) Since the first lateral link (21) is connected to the extension part (5) of the trailing arm (1) forward of the vehicle body side pivot part (E), it becomes more difficult than when connected to the intermediate part of the arm (1). Also, since the first lateral link (21) is located near the vehicle body side pivot portion (E), the length of the link may be short to some extent. Furthermore, since there is no link below the vehicle body side pivot joint (E), the minimum ground clearance can be increased. Furthermore, the pivot joint on the vehicle body side (E
) Since the first lateral link (21) exists in front of the toe rigidity, the span between the third lateral link (21), which contributes to toe rigidity, can be larger than before, and toe rigidity can be maintained high.

Since the first lateral link (21) is connected to this front extension part (5), the first lateral link (21) is connected to the pivot point (E) of the arm (1) compared to the case where it is connected to the intermediate part of the arm (1). Therefore, the link length need only be relatively short as in the embodiment.

できる。(Effects of the Invention) As described above, according to the present invention, the trailing arm is pivotally attached to the vehicle body on the front end side, rotatably supports the wheels on the rear end side, and is disposed in the longitudinal direction of the vehicle body, and the trailing arm has one end. In a vehicle rear suspension consisting of a plurality of lateral links connected to the vehicle body at the other end to a trailing arm and arranged in the lateral direction of the vehicle body, an extension part that projects forward from the vehicle body side pivot point on the front end side of the trailing arm. is formed, and one of the plurality of lateral links is connected to the extension part, so that when this one lateral link is connected to the intermediate part of the trailing arm, the length of the link can be shortened to some extent. Additionally, since there is no lateral link below the pivot point on the vehicle body side of the trailing arm, minimum ground clearance can be achieved, and the lateral link is connected forward of the pivot point on the vehicle body side of the trailing arm. This allows the span between this link and the rear lateral link to be larger than before, making it possible to maintain high toe rigidity.
