Description

  The present invention provides a dash lower panel (dash panel) for partitioning a vehicle compartment and an engine room, a recess in the dash lower panel, and a power train for driving a wheel (rear wheel in the case of an FR vehicle) in the recess. The present invention relates to a vehicle auxiliary equipment arrangement structure in which an auxiliary machine such as an air conditioning unit is provided in a vehicle provided with a unit.

  Conventionally, a heavy powertrain unit (for example, engine and transmission) is arranged near the center in the longitudinal direction of the vehicle to reduce the yaw moment of inertia, thereby improving steering stability and vehicle performance. The vehicle has a structure shown in FIG. In FIG. 13, the configuration when a rotary engine and transmission are used as the power train unit is indicated by a solid line, and the configuration when a reciprocating engine and transmission is used as the power train unit is indicated by a dotted line.

  The conventional structure shown in FIG. 13 is provided with dash panels 90A and 90B that partition the engine room and the vehicle compartment in the front-rear direction. The dash panels 90A and 90B are recessed toward the rear in the center in the vehicle width direction. Recesses 91A, 91B are formed, and a rear part of the rotary engine 92A or reciprocating engine 92B constituting the power train unit is disposed in the recesses 91A, 91B, and at the lower part of the tunnel part 93, that is, outside the vehicle. Includes transmissions 94A and 94B, and air conditioning units 95A and 95B as an example of a vehicular auxiliary unit at the center (so-called center portion) in the vehicle width direction so as to be close to the recesses 91A and 91B. It is arranged.

In comparison between the solid line (rotary engine mounting form) and the dotted line (reciprocating engine mounting form) in FIG. 13, the reciprocating engine 92B is larger than the rotary engine 92A. On the other hand, the air conditioning unit 95B that is set further rearward and disposed in the center portion in the vehicle width direction is set to be smaller than the air conditioning unit 95A when the rotary engine is mounted.
In FIG. 13, arrow F indicates the front of the vehicle, and arrow R indicates the rear of the vehicle.

  When configured as described above, it is possible to reduce the yaw moment of inertia and improve the steering stability and the motion performance of the vehicle, regardless of whether the rotary engine 92A or the reciprocating engine 92B is mounted.

  However, it is required to further reduce the yaw moment of inertia and to improve the steering stability. In this case, the rotary engine 92A or the reciprocating engine 92B may be moved backward further, but the engine 92A 92B interferes with the air conditioning units 95A, 95B, and therefore it is impossible to move backward (rear shift layout).

  Since Patent Document 1 discloses a structure that is substantially the same as the configuration when the rotary engine 92A of FIG. 13 is mounted, there is a problem similar to the conventional structure of FIG. 13 described above.

  On the other hand, in Patent Document 2 and Patent Document 3, an air conditioning unit that air-conditions the interior of the vehicle interior is provided with a vehicle auxiliary device that is disposed in the rear of the vehicle interior in order to achieve further rearrangement of the powertrain unit. Although the structure is disclosed, there is a problem of poor practicality because the passenger compartment or the luggage compartment becomes narrow corresponding to the space occupied by the air conditioning unit.
