ング付ショックアブソーバ８とから構成されている。As shown in FIG. 10, the conventional rear wheel suspension system for F, F, cars includes an axle beam 2 extending in the vehicle width direction between the left and right brake drums 1 and 4;
It consists of a trailing arm 6 and a shock absorber 8 with a coil spring, which are respectively attached between the axle beam 2 and the vehicle body (not shown).

ドリャクス／Ｉ／（図示せず）に固定されている。As shown in FIG. 11, the axle beam 2 is formed into a U-shaped cross section in order to maintain the torsional rigidity at an appropriate value.
To prevent water and dust from accumulating inside the axle beam, the two openings are placed facing downward. In addition,
Reference numeral 9 denotes a stabilizer for reducing vehicle body roll and improving running stability, and it extends into the axle beam 2, and both ends of the stabilizer are attached to Endryax /I/ (not shown) assembled to the axle beam 2. Fixed.
前述したように、従来のアクスルビーム２は、第１１図

ザ９をも変形させることもあった。As mentioned above, the conventional axle beam 2 is arranged with the two openings facing downward, as shown in FIG. 11, so the axle beam side walls 2B and 2C are perpendicular to the vehicle running direction It becomes. Therefore, when the axle beam 2 comes into contact with a large obstacle 11 such as a tall stone on the road while the vehicle is running (arrow A indicates the running direction), the horizontal collision force P with the obstacle 11 is It acts on the axle beam 2, pushes and bends the side wall 2C of the axle beam, deforming the axle beam, and sometimes also deforming the stabilizer 9.

力Ｐを軽減しようとするものである。Therefore, as shown in FIG. 12, an axle beam body securing member 14, which has a downwardly inclined outer peripheral surface 14A of the side wall 12C and extends over the entire width of the vehicle, is welded to the front side wall 12C of the axle beam body 12. Boltnut,
Axle beam structures have been proposed that are attached using adhesive or other fixing means. This causes the inclined outer circumferential surface 14A of the axle beam main body protection member 14 to act as a warp, allowing the axle beam to slide over the obstacle, and the horizontal collision force acting on the axle beam due to contact with the obstacle. This is an attempt to reduce P.

現われた。However, in the axle beam structure according to this new proposal, since the axle beam body protection member 14 is directly attached to the axle beam body 12, the torsional rigidity of the axle beam becomes large, causing problems in the vehicle's behavior when rolling and when driving on rough roads. A new problem has emerged: the wheels have poor ground contact.

とにある。The present invention has been made in view of the above-mentioned problems, and its purpose is to prevent deformation of the axle beam and influence the torsional rigidity of the axle beam by attaching an axle beam body protection member to the axle beam body. The objective is to provide an axle beam structure that does not give rise to

のである。The axle beam structure according to the present invention includes an axle beam body protection member that extends in the vehicle width direction and has a downwardly inclined outer peripheral surface of the front side wall of the axle beam body that extends in the vehicle width direction. This structure is characterized in that the axle beam body retaining member is attached via a spacer and is disposed at a predetermined distance from the axle beam body, and with this configuration, the above object is achieved.
次に、本発明の詳細な説明する。 Next, the present invention will be explained in detail.

平方向衝突力は緩和されてビーム本体の変形が防止され
る。When the axle beam comes into contact with an obstacle on the road while the vehicle is running, first remove the axle beam body protection member (hereinafter simply referred to as a protection member) attached to the front side wall of the axle beam body (hereinafter simply referred to as the beam body). (referred to as parts)
The outer circumferential surface of comes into contact with an obstacle. However, since the outer circumferential surface of this protective member is sloped downward from the front side wall, the protective member acts as a sled, and the beam body and the protective member slide over obstacles as a unit. Can overcome obstacles. Therefore, the horizontal collision force caused by contact with the obstacle is alleviated, and deformation of the beam body is prevented.

で塔乗者に衝撃を与えることもない。As shown in FIG. 3(a), when the axle beam 21 comes into contact with an obstacle 11 protruding on the road while the vehicle is running, the outer circumferential surface 24A of the protection member 24 first comes into contact with the obstacle 11. . Then, the axle beam 21 slides on the outer surface of the obstacle using the outer circumferential surface 24A of the protection member 24 as a sliding surface, and slides over the obstacle 11 as shown in FIGS. 3(b) and (C). You can jump over it. In this way, when the axle beam 21 comes into contact with an obstacle, it can slide on the obstacle and avoid a collision in the opposite state with the obstacle. A large horizontal collision force as shown does not act,
Deformation of the axle beam 21 is prevented. Furthermore, since the large horizontal collision force P does not act on the axle beam 21, no impact is given to the tower occupants.

い。Note that when the axle beam 21 contacts and passes over the obstacle, the axle beam 21 is pushed upward by the obstacle 11, but this axle beam push-up -Bh (Fig. 3 (bl) ) is small, the upward force is absorbed by the shock absorbers 8.8 with coil springs provided at both ends of the axle beam 21, and the axle beam 21 is moved away from the obstacle 11.
The impact force in the vertical direction due to contact with the vehicle is not transmitted to the vehicle body. Furthermore, if the amount of push-up is large, the shock absorbers 8, 8 with coil springs cannot absorb the amount of push-up, and the vehicle body is also pushed upward. Shock absorber with coil spring 8,
8, the impact force in the vertical direction caused by the axle beam 21 coming into contact with the obstacle 11 is relaxed and transmitted to the vehicle body, so that it does not cause a large impact to the occupants.

行時の接ま３性に悪影響を与えることはない。Further, the protective member 24 is arranged at a predetermined distance (equivalent to the thickness of the spacer 25) from the beam main body 22, and the protective member 24
Since only both ends of the axle beam 21 are fixed to the beam body 22 via the spacers 25, the amount of increase in torsional rigidity of the axle beam 21 is small, which improves the stability when the vehicle rolls and the contact stability when driving on rough roads. It has no negative effect on sexuality.

In this way, the cross-sectional shape of the beam main body does not have to be U-shaped as shown in the first to fourth embodiments, but can have a cross-sectional shape that can maintain the torsional rigidity at an appropriate value. It is fine as long as it is something.
