Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment structure of a compressor for a vehicle air conditioner that uses a vehicle running engine as a power source.

[0002]

[Prior Art]

 In many cases, an air conditioner for a vehicle generally uses a vehicle running engine as a power source, a belt-driven compressor is attached to a bracket, and the bracket is attached to an engine body. Further, in many cases, an idler pulley for adjusting the belt tension is provided to adjust the belt tension at the time of initial installation of the belt and after long-term use. Fig. 5 shows an example of the structure of the engine, bracket, compressor, belt, idler pulley, and compressor mounting structure in this case.

In FIG. 5, the compressor is attached to the bracket with compressor attachment bolts, and the bracket is fixed to the engine body with tightening bolts (not shown). The idler pulley is formed integrally with the bracket or is engaged with an idler pulley mounting bracket that is fixed to the bracket with bolts, and the adjustment groove and adjusting bolts provided on the idler pulley mounting bracket allow the engaging position to be adjusted. There is. The belt engages three pulleys, an engine pulley, a compressor pulley, and an idler pulley, and the engine pulley maintains a fixed relationship with the compressor pulley to transmit power. The belt tension increases when the idler pulley is moved downward in the figure by the adjusting bolt and decreases when it is moved upward in the figure.

With this configuration and structure, it is necessary to secure a space for mounting the idler pulley and the idler pulley mounting bracket, and an adjustment work space for the adjustment bolt. In some cases, auxiliary equipment for the engine installed around the engine This may affect the layout, which may cause inconvenience such as inconvenience in checking and adjusting auxiliary equipment.

[0005]

[Problems to be solved by the device]

 In the above-mentioned prior art, since the installation space of the idler pulley for adjusting the belt tension and the work space of the adjustment bolt are prioritized, the consideration of the arrangement of the auxiliary equipment for the engine is insufficient and the maintenance work of the equipment around the engine is troublesome. There was a problem that made me scared. Further, when a problem occurs in the idler pulley, there is a problem that engine power is not transmitted to the compressor even if the compressor does not have a problem.

The purpose of the present invention is to remove the idler pulley for adjusting the belt tension, arrange auxiliary equipment for the engine in the space, and facilitate the maintenance work of the auxiliary equipment. It is to eliminate the inoperability of the compressor due to a malfunction. Another object is to provide a means for adjusting belt tension without the use of idler pulleys.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a bracket fixed to an engine body with an inclined surface, and a mounting groove is provided on the inclined surface so that the compressor can be moved and mounted. The belt tension can be adjusted by moving the position.

Further, a compressor mounting position adjusting means is provided on the bracket and the compressor to facilitate movement of the compressor.

[0009]

[Action]

 The inclined surface of the bracket, the mounting groove, and the means for adjusting the compressor mounting position according to the above-mentioned device function as follows. The bracket is provided with an inclined surface that has a certain angle with respect to the straight line that connects the center of the engine pulley and the center of the compressor pulley, and the mounting groove is arranged on this inclined surface so that the compressor can be moved and installed. To do. Since the compressor can be moved to any position within the range of the mounting groove on the inclined surface of the bracket, move the compressor in the direction in which the distance between the center of the engine pulley and the center of the compressor pulley becomes large. By doing so, the tension of the belt can be increased. The belt tension can be reduced by moving the compressor in the opposite direction.

Further, the compressor mounting position adjusting means arranged for facilitating the movement of the compressor rotates the adjusting bolt so that the direction in which the belt tension is increased or the belt tension is increased. It is possible to act in both directions, that is, the direction in which it becomes smaller.

[0011]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 and 3, the compressor mounting structure includes an engine body 1, a compressor 4, a compressor mounting bolt 6, and a bracket 7. The belt 3 engages the engine pulley 2 engaged with the engine body 1 and the compressor pulley 5 engaged with the compressor 4, and the power of the engine is transmitted from the engine pulley 2 to the compressor pulley 5. It The bracket 7 is provided with an inclined surface 7a having a constant angle θ with respect to a straight line connecting the center of the engine pulley 2 and the center of the compressor pulley 5, and the inclined surface 7a has an inclination direction of the inclined surface 7a. A plurality of mounting grooves 7b having a length in the same direction are provided. The compressor 4 is configured to be fixed to the bracket 7 at an arbitrary position in the mounting groove 7b via the compressor mounting bolt 6 and the mounting groove 7b. That is, the inclined surface 7a and the mounting groove 7b act as follows. When the compressor 4 is moved upward in FIG. 3, the compressor pulley 5 engaged with the compressor 4 moves away from the engine pulley 2, and the engine pulley 2 and the belt 3 engaged with the compressor pulley 5 are separated from each other. The tension generated increases. On the contrary, when the compressor 4 is moved downward in FIG. 3, the tension generated on the belt 3 is reduced. 2 shows a state in which the compressor 4 in FIG. 1 is moved upward along the bracket inclined surface 7a.

When the position of the compressor 4 is moved upward in the drawing, the tension of the belt 3 is increased, and therefore compressor mounting position adjusting means for facilitating this movement will be described with reference to FIG. In FIG. 4, an adjusting bolt receiving seat 7c is provided on the upper end of the bracket 7, and an adjusting bolt receiving seat 4a is provided on the compressor 4, and an adjusting bolt 8 that connects the two receiving seats is used. It is arranged parallel to the direction and is screwed to the adjusting bolt receiving seat 4a. When the adjustment bolt 8 is rotated, the adjustment bolt receiving seat 4a moves upward in the figure, so that the compressor 4 is also moved upward in the figure, and the compressor mounting bolt 6 is moved at a position where the tension of the belt 3 reaches the required value. The compressor 4 can be fixed at any position by tightening.
