Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting device for a horizontal engine.

(Prior art) In a transversely mounted engine in which the engine is mounted on the vehicle body with its longitudinal direction facing the vehicle width direction, generally three sides of the engine and one longitudinal end surface (usually the end surface opposite to the output extraction side) are mounted on the vehicle body. A three-point mount structure is adopted in which an engine mount bracket is attached to each location, and each engine mount bracket is connected to a fixed bracket provided on the vehicle body.

By the way, in this case, since the timing belt on the camshaft drive side is placed on the engine end side where one of the engine mount brackets is placed, mutual interference between this timing belt and the engine mount bracket is to be avoided. For example, as disclosed in Japanese Utility Model Application No. 58-177530, the engine mount bracket on the end surface of the engine is protruded outward at a position inside the timing belt which is stretched annularly on the end surface. It was common to have one.

However, when the engine mount bracket is provided inside the timing belt and its tip is connected to the fixed bracket on the vehicle body side, it is difficult to attach or remove the engine mount bracket at the end of the engine, for example when replacing the timing belt. With the engine mount bracket temporarily supported by a special support device such as a jack, remove the engine mount bracket from the engine side, and replace the belt in this state.
After the work is completed, the engine mount bracket is fixed to the engine end side again, the engine end is supported by the engine mount bracket, and then the support device is removed, which is a very complicated work, which reduces work efficiency. There was a problem that it was inferior.

(Purpose of the invention) The present invention is an attempt to solve the problems pointed out in the above-mentioned section of the prior art. The purpose of this invention is to provide a mounting device that allows the timing belt to be more easily attached and detached in a transversely mounted engine that is attached to a fixed bracket on the vehicle body side through the inside.

(Means for Achieving the Object) In the present invention, as a means for achieving the above object, the engine is mounted on the vehicle body facing in the vehicle width direction, and the longitudinal end of the engine is placed above the end surface. A horizontally mounted engine that is elastically supported by a fixing bolt on the vehicle body side via an engine mount bracket provided on the engine, and a timing belt is stretched over the longitudinal end face of the engine in a state surrounding the engine mount bracket. The engine mount bracket is arranged in parallel in the left-right direction between a first mount bracket whose tip end is connected to the fixing bolt, and the base end of the first mount bracket and the end surface of the engine. a second mount bracket and a third mount bracket, each of which has one end fixed to the proximal end of the first mount bracket and the other end detachably fixed to the end face of the engine; In addition, a belt insertion portion through which the timing belt can be inserted is formed between the second mount bracket and the third mount bracket.

(Function) In the present invention, by the above-mentioned means, the second mount bracket and the third mount bracket are alternately attached and detached, and one free stern portion of the timing belt is gradually moved to the other free spur portion side through the belt insertion portion. By moving the engine mount bracket, it is possible to avoid the engine mount bracket to the outside of the annular shape of the timing belt without interrupting the engine support action of the engine mount bracket (in other words, without using a dedicated support device). It becomes possible.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows the main parts of an automobile engine 2 equipped with a mounting device according to an embodiment of the present invention. The engine 2 is a horizontally mounted engine mounted on the vehicle body with its longitudinal direction facing the vehicle width direction, and includes a pair of side engine mount brackets (not shown) provided on both sides of the engine 2.
A total of three engine mount brackets are provided, including a later-described end face engine mount bracket (hereinafter simply referred to as engine mount bracket) 1 provided on the end face 2a on the opposite output extraction side, and each of these engine mount brackets is fixed to the vehicle body side. It is elastically supported on the vehicle body side by being connected to the fixed bracket 3 which is attached to the frame.

Further, a timing belt 7 is stretched over the end surface 2a of the engine 2, spanning between a cam pulley 4 provided at the top of the engine and a crank pulley 5 provided at the bottom of the engine. In order to avoid mutual interference with the timing belt 7, an engine mount bracket 1, which will be described later, is attached to a portion of the engine end surface 2a located inside the annular shape of the timing belt 7, as shown in FIG. ing. The structure and function of this engine mount bracket 1 will be explained below with reference to FIGS. 1 to 3.

The engine mount bracket 1 is composed of a combination of three mount brackets: a first mount bracket 11, a second mount bracket 12, and a third mount bracket 13. The first mount bracket 11 is located at the tip of the engine mount bracket 1, that is, closer to the fixed bracket 3 on the vehicle body side.
It is equipped with 4.

The second mount bracket 12 and the third mount bracket 13 are both located at the base end of the engine mount bracket 1, that is, closer to the engine end surface 2a, and are located closer to the base end 11b of the first mount bracket 11. and the engine end surface 2a, and are arranged side by side in the lateral direction (left-right direction). The second mount bracket 12 and the third mount bracket 13 are arranged in a line-symmetric shape opposite to each other across the axis of the engine mount bracket 1.
distal side flange portions 12a, 13a that serve as attachment portions to the base end portion 11b of the mount bracket 11;
It has proximal flange portions 12b, 13b which serve as attachment portions to the engine end surface 2a, and beam portions 12c, 13c located between these two flange portions.

The second mount bracket 12 and the third mount bracket 13 are attached to the respective beam portions 1.
2c and 13c are aligned, the base end 11a of the first mount bracket 11 and the engine end surface 2
They are each removably bolted to a. And this second mount bracket 1

A belt insertion portion 8 having a size that allows the timing belt 7 to be inserted in the vertical direction is formed between c and 13c. When the engine mount bracket 1 is attached to the engine 2, the timing belt 7 is inserted so that both free spun parts 7A and 7B of the timing belt 7 are located on the sides of the belt insertion part 8, as shown in FIG. The formation position of the portion 8 is set.

When the engine mount bracket 1 is attached to the end surface 2a of the engine 2, the engine mount bracket 1 is positioned inside the annular timing belt 7, as shown in FIG.
Therefore, when the timing belt 7 is replaced, it is necessary to move the engine mount bracket 1 to the outside of the timing belt 7. However, in that case, the method of warping the engine mount bracket 1 and removing it from the end surface 2a of the engine 2 to replace the belt requires a dedicated support device and is complicated, so the workability is not good. As already mentioned.

However, in this embodiment, by applying the present invention, the engine mount bracket 1 has a split structure, and the second mount bracket 12 and the third mount bracket
The belt insertion portion 8 is inserted between the mount bracket 13 of

That is, for example, when removing the timing belt 7 (see FIG. 1) that is in a tensioned state, first, the idlers 6, 6 are moved appropriately to loosen the timing belt 7 sufficiently.

Next, one of the second mount bracket 12 and the third mount bracket 13, for example, fixing bolts 22, 22 and 24, 24, are unscrewed to attach the third mount bracket 13 to the first mount bracket. 11 and the engine end face 2a. Therefore, in this state, the engine end is supported by the second mount bracket 12 and the first mount bracket 11.

Next, one of the free stern portions 7A of the timing belt 7 is drawn toward the second mount bracket 12, and then the third mount bracket 13 is placed again outside the free spar portion 7A, and this is replaced with the first mount bracket 13. Bolts are fastened to the base end 11b of the mount bracket 11 and the engine end face 2a (the state shown in FIG. 2). At this time, one free spun portion 7A of the timing belt 7 is inserted into the belt insertion portion 8, as shown by the reference numeral 7A' in FIG.

Next, this time fixing bolts 21, 21 and 2

Pull it out to the B side and position it outside the mounting position of the second mount bracket 12 (second
(state indicated by reference numeral 7A'' in the figure).

In this state, attach the second mount bracket 1 again.
2 is fixed to the first mount bracket 11 and the engine end face 2a side using fixing bolts 21, 21 and 23, 23 (the state shown in FIG. 2).

With this, one free stern section 7A of the timing belt 7 is moved from the outside of the third mount bracket 13 over the third mount bracket 13 and the second mount bracket 12 to the other free spur section 7B side. Ru. Incidentally, when installing the timing belt 7, by going through the reverse procedure of the above-mentioned work procedure, one of the free spun parts 7A of the timing belt 7 is attached to the second mount bracket 12 and the second mount bracket 12 from the outside of the second mount bracket 12. The third mounting bracket 13 can be moved beyond the third mounting bracket 13 to the outside of the third mounting bracket 13.

As described above, according to the mounting device of this embodiment, even though the engine mount bracket 1 is located inside the annular shape of the timing belt 7, it is possible to completely remove the engine mount bracket 1 from the engine 2 side. The timing belt 7 can be attached and detached without any trouble. Therefore, there is no need to support the engine end face 2a with a support device such as a jack, and the timing belt 7
