[0001]

[Industrial applications]

 The present invention relates to a mechanical supercharger for a vehicle.

[0002]

[Prior Art]

 7 and 8 are views showing a conventional engine. Fig. 7 (Automotive Engineering June 1989, page 112) is a drawing of the vertically installed engine 201 seen from the oblique front of the vehicle, and Fig. 8 (Automotive Engineering March 1990, page 82) shows the horizontally installed engine 203 as a flywheel. It is the drawing seen from the other side of the eel. As shown in FIG. 7, a pulley 205 connected to a crankshaft is arranged on one side of the engine, and an alternator 207 driven by a pulley 205 and a power transmission are driven on the same plane as the pulley 205. A steering oil pump 209, an air pump 211, and the like are arranged.

[0003]

[Problems to be solved by the device]

 As described above, conventionally, auxiliary machinery is driven via the belt transmission mechanism, so that each auxiliary machinery is concentrated on one side of the engine, and it is difficult to arrange the mechanical supercharger due to lack of installation space. For example, there is a problem that the mechanical supercharger 213 cannot be assembled or removed unless the air compressor 215 for air conditioning, the oil pump 213 for power steering, the oil generator 217, etc. are removed. In addition to this, the concentration of auxiliaries in one place makes the weight unbalanced, making it difficult to balance the vehicle.

Therefore, in the present invention, the supercharger is arranged in an empty space to ease the centralized arrangement of the auxiliary machines, and also to effectively use the space to facilitate the assembly of the supercharger. The purpose of the present invention is to provide a mechanical supercharger that improves the balance of the vehicle.

[0005]

[Means for Solving the Problems]

 The mechanical supercharger of the present invention has a supercharger arranged in an empty space and a propeller shaft connected to a joint capable of converting the direction of force, and transmits a torque of the engine to the supercharger. And a mechanism.

[0006]

[Action]

 The supercharger is rotationally driven by the driving force of the engine via the torque transmission mechanism. This torque transmission mechanism can guide the driving force to an arbitrary place by means of the joint capable of converting the direction of force and the propeller shaft, and therefore the supercharger can be arranged in the empty space of the engine room.

[0007] Thus, the space can be effectively used, and since the supercharger is moved from the centralized location of the other accessories, it is easy to assemble and remove, and the deviation of the weight is alleviated. It becomes easier to balance the vehicle.

【Example】

 The first embodiment will be described with reference to FIGS. 1 and 2 show this embodiment and an engine, and FIG. 3 shows a power system of an FR (front engine / rear drive) vehicle using this engine. The members without reference numerals are not shown.

This power system includes a vertically installed engine 1, a transmission 3, a propeller shaft 5, a rear differential 7 (a rear wheel side differential device), rear axles 9, 11, left and right rear wheels 13, 15, left and right front wheels. It is composed of 17, 19 and the like. The driving force of the engine 1 is distributed to the left and right rear wheels 13, 15 via the transmission 3, the propeller shaft 5, and the rear differential 7.

As shown in FIGS. 1 and 2, a mechanical supercharger 21 of this embodiment is attached to the engine 1. The mechanical supercharger 21 includes a centrifugal supercharger 23 and a torque transmission mechanism 25.

The supercharger 23 is attached to the engine 1 by a bracket 27, and a propeller in which a belt type continuously variable transmission mechanism 29 and universal joints 31 and 33 (joints capable of converting force directions) are connected at both ends. It is connected to the crankshaft of the engine 1 via a torque transmission mechanism 25 having a shaft 35 and a belt transmission mechanism 37.

The belt transmission mechanism 37 includes a pulley 43 on the rotating shaft 41 side attached to the engine 1 by a bracket 39, a pulley 45 connected to the crankshaft, and a belt 47 connecting the pulleys 43, 45. ing. The rotation of the engine 1 is transmitted from the rotating shaft 41 to the belt type continuously variable transmission mechanism 29 at a constant speed via the joint 31, the propeller shaft 35, and the joint 33.

The belt type continuously variable transmission mechanism 29 includes a pair of speed change pulleys 49, 51 and a belt 53 connecting these pulleys. By adjusting the pulley pitch diameter of each pulley 49, 51, the input is made in accordance with the change in the engine speed. The rotation is changed to drive the supercharger 23 at a substantially constant number of revolutions, and the supercharger 23 supplies intake air with increased pressure to the engine.

With the joints 31 and 33 and the propeller shaft 35, the direction of the driving force can be changed to move the driving point to an arbitrary position. Therefore, the supercharger 23 is indicated by an arrow 55 in FIG. It was possible to move it from and to place it in the empty space on the transmission 3 side indicated by arrow 57.

Therefore, the vacant space can be effectively used, and the supercharger 23 can be easily assembled and removed without being interfered with other auxiliary machines. In addition, the weight concentration due to auxiliary equipment is alleviated, and the vehicle is easily balanced accordingly. Compared to FF (front engine / front drive) vehicles, especially FR vehicles do not have a drive system on the front wheel side (located on the rear side of the engine), so the center of gravity moves to the front side of the engine and at the rear of the engine. An empty space is formed in the space, but this space can be used effectively and the front and rear of the engine can be easily balanced.

As shown by the broken line in FIG. 1, a power take-out device 59 may be provided in the transmission 3 and the supercharger 23 may be driven from here by a torque transmission mechanism.

Next, a second embodiment will be described with reference to FIGS. 4 to 6. 4 and 5 show this embodiment and the engine, and FIG. 6 shows the power system of an FF vehicle using this engine. The members without reference numerals are not shown. The right side of FIG. 4, the lower side of FIG. 5 and the upper side of FIG. 6 correspond to the front of the vehicle.

This power system includes a horizontal engine 61, a transmission 63, a front differential 67 (a front wheel side differential device), front axles 69 and 71, left and right front wheels 73 and 75, left and right rear wheels 77 and 79, and the like. The driving force of the engine 61 is transmitted to the front differential 67 by meshing between the output gear 81 of the transmission 63 and the ring gear 83 of the front differential 67, and is distributed to the left and right front wheels 73, 75.

As shown in FIGS. 4 and 5, the engine 61 is provided with the mechanical supercharger 85 of this embodiment. The mechanical supercharger 85 includes a centrifugal supercharger 87 and a torque transmission mechanism 89.

The supercharger 87 is attached to the engine 61 by a bracket 91, a belt type continuously variable transmission 93, a propeller shaft 99 having universal joints 95 and 97 (joints) connected to both ends, and a belt transmission mechanism. Is connected to the crankshaft of the engine 61 via a torque transmission mechanism 89 having

The belt transmission mechanism 101 includes a pulley 107 attached to the engine 61 by a bracket 103 on the rotating shaft 105 side, a pulley 109 connected to the crankshaft, and a belt 111 connecting the pulleys 107 and 109. ing. The rotation of the engine 61 is transmitted from the rotary shaft 105 through the joint 95, the propeller shaft 99, and the joint 97 to the belt type continuously variable transmission mechanism 93 at a constant speed.

The belt type continuously variable transmission mechanism 93 includes a pair of variable-diameter pulleys 113 and 115 and a belt 117 that connects these pulleys to each other, and adjusts the pulley pitch diameters of the pulleys 113 and 115 to respond to changes in the engine speed. The input rotation is changed to drive the supercharger 87 at a substantially constant number of rotations. The supercharger 87 supplies the intake air whose pressure is increased to the engine 61 via the intercooler 119.

The joints 95 and 97 and the propeller shaft 99 can change the direction of the driving force to move the driving point to an arbitrary position. Therefore, the supercharger 87 is indicated by an arrow 121 in FIG. It was possible to move from and arrange in the empty space shown by arrow 123.

In this way, the vacant space can be effectively used, and the supercharger 87 can be easily assembled and removed without interference with other auxiliary machines. In addition, the imbalance in weight due to the concentration of accessories in the area indicated by arrow 121 was alleviated, making it easier to balance the vehicle.
