Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a support device for a differential carrier.

(Prior Art) In a conventional differential carrier support device, as shown in FIGS. 3 and 4, the differential carrier 11
The support member 12, which supports the front end 11a of It is known that the structure is made of plate material. Further, a rear support member 17 is attached to the rear of the differential carrier 11.
The tip end of the rear support member 17 is supported via a suitable elastic body by a support body 19 installed on a support member 18 that extends below the rear support member 17 in the width direction of the vehicle body.

(Problem to be Solved by the Invention) However, in the above configuration, since the support member 12 is made of a plate material with a vertical plate surface in the support portion of the front end portion 11a of the differential carrier 11, the rigidity in the vertical direction is not sufficient. Even so, the rigidity of the support member 11 was small in the front-rear direction indicated by the arrow in FIG. 3, and there was a problem in stably supporting the differential carrier. Note that if the plate surface of the support member is arranged horizontally, the rigidity in the vertical direction will be insufficient, and if a press-formed support member is used to obtain sufficient rigidity in both the horizontal and vertical directions, the cost will be reduced. There is a problem with getting high.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a differential carrier support device that provides sufficient rigidity in the vertical and horizontal directions and can be constructed at low cost.

(Means for Solving the Problems) In order to achieve the above object, the present invention uses a support member that supports the front end of the differential carrier as a plate whose plate surface is in a vertical position and whose both ends are supported on the frame side. a horizontal support member, which is made of a plate perpendicular to the plate surface of the support member, whose both ends are integrally fixed to the support member, and whose center portion extends toward the center side of the differential carrier; A central portion of the horizontal support member is coupled and fixed to the differential carrier.

(Function) Since the present invention has the above configuration, rigidity in the vertical direction can be obtained by the support member made of a plate material with a vertical plate surface, and the horizontal support member made of a plate material fixed vertically to this support member can be used. Rigidity in the longitudinal direction is also obtained, and since the support member and the horizontal support member are each made of plate material, they can be constructed at low cost, and high rigidity can be obtained by integrating both.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes a differential carrier, and a central portion of a support member 2 is fixed to a front end portion 1a of the differential carrier with a bolt 3. The support member 2 is made of an elongated plate with a vertical plate surface, and both ends 2a of the support member 2 are supported by a support body 4 fixed to the vehicle body frame via an elastic body (not shown). In addition, this support member 2
This support member 2 is placed at an appropriate distance from both ends of the support member 2.
Both ends 5a of the horizontal support member 5 perpendicular to the plate surface of
are fixed together by welding. Both ends 5a of the horizontal support member 5 are fixed to the support member 2, and the middle portion is made of a narrow plate member with a trapezoidal planar shape extending toward the center of the differential carrier 1. There is. And this horizontal support member 5
The center portion of is fixed to the differential carrier 1 with a bolt 6.

On the other hand, a rear support member 7 is attached to the rear of the differential carrier 1. This rear support member 7
is supported by a support member 8 disposed on the vehicle body frame so as to cross the lower position in the vehicle body width direction. Specifically, the upper end portion of the support body 9 installed on the support member 8 is fitted into the support portion 7a formed at the tip portion of the rear support member 7, and is supported via an appropriate elastic body (not shown). has been done.

In the above configuration, since the support member 2 is made of a plate material with a vertical plate surface, it has high rigidity in the vertical direction and can firmly support the front end portion 1a of the differential carrier 1 in the vertical direction.
Rigidity in the longitudinal direction is also obtained by the horizontal support member 5 made of a plate material perpendicular to the plate surface of the differential carrier 1.
The front end portion 1a of the front end portion 1a can be firmly supported in the front-back direction as well.
Furthermore, since the support member 2 and the horizontal support member 5 are each made of plate material, they can be constructed at low cost, and since they are integrated, high rigidity can be obtained even though they are each made of a plate material. Furthermore, by increasing the amount L of the intermediate portion of the horizontal support member 5 extending toward the center of the differential carrier 1, higher rigidity in the longitudinal direction can be obtained.

The present invention is not limited to the above embodiments. For example, the shapes of the support member 2 and the horizontal support member 5, the support structure at both ends of the support member 2, the support structure at the rear of the differential carrier 1, etc. can be changed arbitrarily.

(Effects of the invention) As described above, according to the differential carrier support device of the present invention, rigidity in the vertical direction is obtained by the support member made of a plate material with a vertical plate surface, and it is integrally fixed to the support member perpendicularly. The horizontal support member made of a flat plate material provides rigidity in the front-rear direction, making it possible to stably support the differential carrier. Furthermore, since the support member and the horizontal support member are each made of plate material, they can be constructed at low cost, and by integrating the two, high rigidity can be obtained, which is a great practical effect.
