Description of the Related Art Generally, a vehicle suspension device is connected to and supported by a vehicle body through a suspension cross member oriented in the vehicle width direction in order to improve the assemblability with respect to the vehicle body and the strength and rigidity against a lateral load. (See Japanese Utility Model Laid-Open No. 62-202402). For example,
In a suspension cross member for supporting a strut type or double wishbone type suspension device having an A-shaped arm, mounting portions extending in the vehicle front-rear direction are formed at both ends of a cross member body extending in the vehicle width direction. The inner ends of both front and rear arm portions of the A-shaped arm are connected and supported in the vicinity of both front and rear ends of the front portion, and the arm portion of the front and rear arm portions facing the vehicle width direction is arranged at a position corresponding to the cross member body. The cross member body is configured to effectively receive the lateral load input from the arm portion in the vehicle width direction.

以外の構成において前記マウント装置59の取付構造と
同様の構成なので、その詳細な説明を省略する。The mounting structure of the mounting devices 59 and 62 provided on the left and right curved portions 18a will be described. Since the mounting structures of the mounting devices 59 and 62 are substantially bilaterally symmetrical, the mounting structure of the left mounting device 59 will be described with reference to FIG. Thus, the tubular portion 65 extending downward is integrally formed on the upper wall portion of the curved portion 18 a, and the reinforcing portion 4 corresponding to the tubular portion 65 is formed.
An opening 66 is formed in the upper wall portion of 6a, and a substantially cylindrical outer cylinder 67 is fixed in the cylindrical portion 65 and the opening 66 so that the outer cylinder 67 has an upper end portion for retaining. Flange part 67
a is formed, and a substantially cylindrical inner cylinder 68 is provided inside the outer cylinder 67 concentrically with the outer cylinder 67 via a rubber bush 69, and a flange portion 67 a is provided at the upper end of the rubber bush 69.

Since the front side frame 13 and the vehicle body side members in the vicinity thereof are crushed in order from the front side to absorb the collision energy, in order to efficiently absorb the collision energy at the time of a frontal collision, the suspension cross member 1 having high strength and rigidity is used.
It is desirable to prevent the bulging by the A-shaped arm 7 and the A-shaped arm 36 and prevent the uncrushed parts of the vehicle body side member from remaining.

を少なく出来る。The arm member 21 of the suspension cross member 17 is formed in a U-shaped cross-section that opens forward and downward, and has strength against a rearward load.
Since the rigidity is set to be relatively low, uncrushed parts of the vehicle body side member corresponding to the arm member 21 due to the arm member 21 being stretched during a frontal collision are prevented. A positioning pin 23 is provided near the front end of the arm member 21, and the arm member 21 is fixed to the first mounting bracket 14 via a bolt member 30 provided behind the positioning pin 23. It is possible to set the coupling strength of the portion in the vicinity of the front end of the first attachment bracket 14 to be low, and to reduce the tension of the arm member 21 during a frontal collision.

対応する車体側部材の潰れ残りが防止される。Since the bracket member 22 of the suspension cross member 17 is fixed to the second mounting bracket 15 via the bolt member 31 which is inserted through the elongated bolt hole 27, a large rearward load is applied to the suspension cross member. When acting on the member 17, the bolt member 31 fastened to the nut member 28 of the second bracket 15
Relatively moves forward along the bolt hole 27, and the impact load when the bolt member 31 is locked at the front end portion of the bolt hole 27 promotes breakage of the bolt member 31 or the front end portion of the bolt hole 27. .. Therefore, when a large rearward load acts on the suspension cross member 17 during a frontal collision, the bracket member 22 separates from the second mounting bracket 15 together with the front arm portion 36a of the A-shaped arm 36.
The uncrushed portion of the vehicle body side member corresponding to the A-shaped arm 36 due to the A-shaped arm 36 being stretched is prevented.

することが出来る。The bracket member 22 is firmly connected to the second mounting bracket 15 through the two bolt members 31, and the bracket member 22 has the inclined portion 22b.
Since it is fixed to the pair of front and rear inclined wall portions 18b that expand downwards through the cross member main body 18 through, the attachment strength of the suspension cross member 17 against the vertical load acting on the front arm portion 36 is increased. You can secure enough. In addition, the reinforcing portions 2 before and after the bracket member 22.
Since 2a is fixed to both front and rear walls of the cross member main body 18, the mounting strength of the bracket member 22 to the cross member main body 18 can be improved, and at the same time, the cross member main body 18 at the inner end of the front arm portion of the suspension device can be improved. The mounting strength can be improved. The strength and rigidity of the mounting brackets 14 to 16 are set to be higher toward the rear side, so that the mounting brackets 14 to 16 can effectively absorb the collision energy at the time of a frontal collision, thereby further improving the safety of passengers. Can be further improved. Further, since the third mounting bracket 16 having the highest strength and rigidity is arranged below the dash panel 43, it is possible to effectively prevent the dash panel 43 from being deformed toward the vehicle compartment side in the event of a frontal collision.

一層効果的に防止出来る。The second mounting bracket 15 is attached to the tie rod 47.
The suspension cross member 17 separated from the first mounting bracket 15 is promoted to move downward because it is located higher and rearward than the tie rod 47 and vertically overlaps the tie rod 47 in the longitudinal direction of the vehicle body by a predetermined distance. By allowing the steering rack unit 45 to escape downward during a frontal collision, the backward movement of the steering handle 50 can be prevented without complicating the steering force transmission system from the steering handle 50 to the steering rack unit 45. Further, since the inclined surface 15b is formed on the front end surface of the second mounting bracket 15 so as to recede toward the lower end, the downward movement of the suspension cross member 17 separated from the second mounting bracket 15 is further promoted, and the steering wheel is steered. The backward movement of the handle 50 can be prevented more reliably. Further, since the cross member main body 18 is fixed to the first mounting bracket 14 via the arm member 21 which is inclined forward and upward, the cross member main body 18 is supported by the rearward load acting on the arm member 21 during a frontal collision. 6 is rotated in the direction indicated by the arrow in FIG. 6, the downward movement of the steering rack unit 45 is promoted, and the backward movement of the steering handle 50 can be prevented more effectively.

Moreover, since the mounting devices 59 and 62 of the differential device 5 are provided in the portion reinforced by the reinforcing portion 46a, the mounting strength of the mounting devices 59 and 62 can be improved.
