Description

[Detailed description of the invention] This invention includes a square frame and a rubber member fixed to the inner surfaces of both inclined walls of the square frame, and the square frame is attached to the chassis frame side structure. Improvement of a cab support for a cab over type vehicle in which the cab support is fixed and supports the conical engaging portion of the cab side mount bracket by both rubber members, and more specifically, by devising the structure of the rubber member, productivity can be increased. This invention relates to an improvement in which a molding die with improved performance can be obtained.

The conventional cab support a of the above type is the first
The structure is as shown in FIGS. That is, a square frame b, cylindrical or prismatic rubber members d and d' fixed to face the inner surfaces of both inclined walls c and c', and outer surfaces of both inclined walls c and c'. It is constituted by reinforcing members (in the illustrated case, U-shaped) e and e' fixed to the reinforcing members e and e'. This cab support a is
As shown in FIGS. 3 and 4, the round frame b is fixed to the chassis frame side structure f, and the lower part of the cab side mount bracket g is engaged with the lower part of the cab side mount bracket g using both rubber members d and d'. Supports part h.

By the way, in such a cab support a, after the reinforcing members e and e' are assembled (welded) to the square frame b, the rubber members d and d' are fixed to the rubber members d and d'. Molding and fixing are performed simultaneously using a mold i as shown in FIG.

However, in the case of the conventional structure, the rubber member d,
Since d′ is cylindrical or prismatic, the sixth
As shown in the figure, the splitting direction of the mold i had to be the direction A, which allows the mold to be split. For this reason,
Molding die i is composed of divided dies j and k in the A direction, so when making a large number of pieces using one molding die,
As shown in FIG. 7, the mold i is long and heavy, so it is usually made into a single mold as shown in FIG. Therefore, productivity was low and costs were high.

In addition, as a cab support, there is also a
There is a type shown in Publication No. 18814, etc.

Therefore, the present invention provides a structure for a cab support for a cab-over type vehicle that can solve the above-mentioned problems, that is, can form a large number of pieces using a short mold.

An embodiment of this invention will be described below with reference to FIG.

In the figure, 1 is a square frame, 2 and 2' are reinforcing members, and 3 and 3' are rubber members.

The frame 1 and reinforcing members 2, 2' have the same structure as the conventional one.

The basic shape of the rubber members 3, 3' is cylindrical or prismatic as in the prior art, and when installed on the inclined walls 4, 4' of the cross-shaped frame 1 as shown in the figure, the inner shoulder 5 of the central vertical cross section of the rubber members 3, 3' , 5' portions are perpendicular to the horizontal base 6 of the square frame 1. The inner shoulders 5, 5' are further widened at a position where the bearing surfaces 7, 7' are extended, that is, any position within the range of positions parallel to the inclination angle θ of the inclined walls 4, 4' (imaginary line). It may be tilted to

The mold 9 used to manufacture the cab support 8 having such a structure can be divided into divided molds 10 and 11 with the mold dividing direction in the B direction as shown in FIG. Therefore, when producing a large number of cab supports 8, the cab supports 8 can be arranged as shown in FIG. 10, improving productivity and reducing costs.

In summary, the cab support for a cab-over type vehicle according to the present invention has a cross-shaped frame and a rubber member fixed to the inner surfaces of both inclined walls of the cross-shaped frame in a manner that faces the inner surfaces of the cross-shaped frame. In a cab support for a cab-over type vehicle, the cab support is fixed to a frame-side structure, and the two rubber members support a curved engaging portion of a cab-side mount bracket, wherein the rubber member is installed on an inclined wall of the curved frame. The inner shoulder part of the central longitudinal section is inclined within the range of the angle of inclination of the inclined wall from the position perpendicular to the horizontal base of the square frame. As mentioned above, it becomes possible to use a mold that can mold a large number of molds, improving productivity and reducing costs.
