る。(Prior art) The suspension member or subframe is
The vehicle includes a pair of longitudinal members arranged in the longitudinal direction on both sides of the vehicle body, and a cross member arranged in the width direction of the vehicle body and coupled to both longitudinal members. A suspension arm is pivotally attached to each longitudinal member, and a steering gear box is supported by a bracket provided on the cross member.

られている。 Conventionally, as shown in FIG. 5, the cross member 10 is welded to a main body portion 12 formed to have an approximately inverted U-shaped cross section and a pair of flange portions 14 provided on the front and rear sides of the main body portion 12. It is formed by a bottom portion 16. On the other hand, bracket 18
a member 20 that is welded to the main body portion 12 and protrudes toward the front; and a protrusion portion 22 that is part of the bottom portion 16 and extends forward and is welded to the member 20.
The member 20 is formed by the protruding portion 22.
is reinforced, increasing the overall rigidity of the bracket 18.

組付工程を煩雑にしている。(Problems to be Solved by the Invention) Since the protruding portion 22 is formed by protruding a portion of the bottom portion 16 forward, the yield of the bottom portion 16 is poor. In addition, as shown in FIG. 4, the steering gear box 24 to be supported by the bracket 18 is provided with a housing 26 for accommodating a gear device, so that the steering wheel 28 can be used for right-hand wheels or left-hand wheels. The position of the bracket 18 differs depending on the cross member 1.
Two types of bottom portions 16 are required, which complicates the manufacturing and assembly process.

分以外の板厚が増大する結果、重量増となり、コ
スト高の一因となる。 The cross member is formed to increase its rigidity by devising its cross-sectional shape, and originally thick plates are not used. Therefore, the rigidity of the bracket 18 tends to be insufficient when reinforced by the protrusion 22, and if the thickness of the bottom part 16 is increased in order to increase this, the thickness of the plate other than the part necessary to increase the rigidity of the bracket 18 will increase. As a result, the weight increases, which becomes a cause of high costs.

ることにある。 The purpose of this invention is to improve the yield of the bottom of the cross member, to be able to handle both right-hand and left-hand use with one type of bottom, and to increase the thickness of only the parts necessary to increase the rigidity of the bracket. An object of the present invention is to provide a steering gear box support bracket that can be selected.

前記補強部は、最も低い部分に貫通穴を有する。(Means for Solving the Problems) The present invention is a bracket for supporting a steering gear box, which includes a first member and a second member each fixed to a cross member disposed in the width direction of a vehicle body. The first member is bent forward from the cross member into a substantially S-shape when viewed from the side, and has a cross section in the width direction of the vehicle body formed into a substantially inverted U-shape, and is a member for mounting the steering gear box. It has a contact portion and a pair of flanges provided on both sides of the contact portion. The second member includes a reinforcing portion that is bent forward from the cross member into a substantially dogleg shape in a side view, and has a substantially U-shaped cross section in the width direction of the vehicle body; and a pair of flange portions provided on both sides of the reinforcing portion, each of which is fixed to the pair of flange portions. The reinforcing portion of the second member has a through hole at the lowest portion.

理由から、ブラケツトの剛性を十分に高めること
が可能である。(Operations and Effects) The second member is not formed by extending a part of the bottom of the cross member, but is formed as an independent component and is fixed to the cross member, so that
The plate thickness can be arbitrarily selected regardless of the cross member. In addition, since the cross section of the abutting portion of the first member in the width direction of the vehicle body is approximately in an inverted U-shape, and the cross section of the reinforcing portion of the second member in the width direction of the vehicle body is approximately U-shaped, the contact portion The moment of inertia of the cross member and the reinforcing portion can be made larger than the moment of inertia of a conventional bracket in which the second member is formed by an overhanging portion of the bottom of the cross member. For the above two reasons, it is possible to sufficiently increase the rigidity of the bracket.

リングギヤボツクスの特に左右方向に向く大入力

止して、クロスメンバの変形を抑え、車両の旋回
性能を向上できる。 By increasing the rigidity of the bracket, large inputs to the steering gear box, particularly in the left and right directions, can be prevented from being transmitted from the bracket to the cross member, suppressing deformation of the cross member, and improving the turning performance of the vehicle.
第２部材の補強部が、最も低い部分に貫通穴を
有するため、水やダスト等を排出でき、防錆性能
を高めることができる。 Since the reinforcing portion of the second member has a through hole at the lowest portion, water, dust, etc. can be discharged, and rust prevention performance can be improved.

で、底部の製作および組付けの際の煩雑はなくな
る。 Since the bottom of the cross member does not require a portion corresponding to a conventional protrusion, the yield is improved. Further, since one type of bottom part can be used for both right-hand and left-hand steering wheels, there is no need to worry about making and assembling the bottom part.

It consists of The first member 34 is formed of a plate material, and as shown in FIGS. 1 to 3,
A flat fixed part 35a, an abutting part 35b which is bent forward from the fixed part 35a into a substantially S-shape in side view, and whose cross section in the width direction of the vehicle body is formed into an inverted U-shape. It consists of a pair of flange portions 35c located on both sides of the contact portion 35b and extending forward from the fixed portion 35a. The fixing portion 35a is welded to the top portion of the main body portion 12 of the cross member 10, the portion of the pair of flange portions 35c that contacts the front portion of the main body portion 12 is welded to the front portion of the main body portion 12, and the first The member 34 projects forward from the cross member 10.

一対のフランジ部３５ｃに溶接されている。 The second member 36 is formed of a plate material, and includes a flat fixed part 37a that slopes upward, and is bent forward from the fixed part 37a into a dogleg shape in a side view, and is bent in the width direction of the vehicle body. The reinforcing portion 37b has a U-shaped cross section, and the reinforcing portion 37
It consists of a pair of flange parts 37c on both sides of b and extending forward from the fixed part 37a. Fixed part 37
a is welded to the front part of the main body part 12 of the cross member 10, a part of the reinforcing part 37b is welded to the flange part 14, and the second member 36 is welded to the front part of the main body part 12 of the cross member 10.
It protrudes forward from. And the second member 3
The pair of flange portions 37c of No. 6 are welded to the pair of flange portions 35c of the first member 34.

加わる左右方向の入力に対する抵抗を増すことが
できる。 Since the second member 36 is formed as a component independent from the cross member 10, its plate thickness and shape can be arbitrarily selected. In the example shown in FIG. 1, the reinforcing portion 37b of the second member 36 is formed in a tapered shape from the fixed portion 37a in plan view, and the length of its tip in the width direction of the vehicle body is the same as that of the first member 34. Contact part 35
The tip of b is larger than the length in the width direction of the vehicle body.
In this way, the rigidity of the bracket 30 can be greatly increased, and the resistance to lateral inputs applied from the steering gear box can be increased.

を向上できる。 Since the second member 36 is formed from an independent component, the second member 36 can be formed into any shape without being influenced by the shape or size of the bottom portion 32 of the cross member 10. Therefore, as described above, the reinforcing portion 37b of the second member 36 is
It can be bent forward from point a into a dogleg shape in side view, and can be formed so that the cross section in the width direction of the vehicle body has a U shape. By forming the second member 36 in this manner, the welding reference hole 38 provided in the lower part of the reinforcing portion 37b can be used as a discharge hole for water, dust, etc., and the rust prevention performance of the bracket 30 can be improved. .
