1 is a front view of a front wheel of an automobile (first embodiment). FIG. 2 is a view taken along line 2-2 in FIG. 1 (first embodiment). The front view of the front wheel of a motor vehicle (2nd Embodiment).

  Hereinafter, a first embodiment of the present invention will be described with reference to FIG. 1 and FIG.

  As shown in FIGS. 1 and 2, an engine room 11 in which an engine, a transmission, and a differential gear (not shown) are housed and a wheel house 12 in which wheels W are housed are arranged on the outer surface in the vehicle width direction of the front side frame 13. It is partitioned off by the combined wheel house inner wall 14. A front subframe 15 is disposed below the front side frame 13, and the side of the engine room 11 is covered with a splash guard 16 that joins the front side frame 13 and the front subframe 15. A lower portion of the engine room 11 is covered with an under cover 17 coupled to the lower surface.

  The strut-type suspension 18 includes a lower arm 21 pivotally supported by a bracket 19 provided at an outer end in the vehicle width direction of the front subframe 15 via a rubber bush joint 20 so that the inner end can swing up and down. A lower portion of the knuckle 23 is pivotally supported on the outer end of the ball 21 via a ball joint 22. The upper end of the damper 24 whose lower end is fixed to the upper part of the knuckle 23 is fixed to the wheel house ceiling wall 25 connected to the upper end of the wheel house inner wall 14. A suspension spring 26 made of a coil spring is disposed so as to surround the upper outer periphery of the damper 24.

  A drive shaft 27 extending in the left-right direction from a differential gear disposed in the engine room 11 extends through the opening 16 a formed in the splash guard 16 into the wheel house 12 and is rotatably supported inside the knuckle 23. It is connected to an axle (not shown) via a ball joint 28. The ball joint 28 is covered with a rubber boot 29.

  As the suspension 18 moves up and down, the knuckle 23, the ball joint 28 and the drive shaft 27 also move up and down, so that the opening 16a formed in the splash guard 16 through which the drive shaft 27 passes is formed to a predetermined size. A bearing 31 is provided at the center of the outer end of a rubber boot 30 having an inner end outer peripheral portion coupled to the opening 16a of the splash guard 16, and the drive shaft 27 penetrates the bearing 31 so as to be relatively rotatable.

  Next, the operation of the first embodiment of the present invention having the above configuration will be described.

  A drive shaft 27 driven by the engine disposed in the engine room 11 extends through the opening 16a of the splash guard 16 and the bearing 31 of the boot 30 into the wheel house 12, and is rotatably supported by the knuckle 23. The wheel W is driven via the ball joint 28. When the wheel W bumps and rebounds together with the knuckle 23 while the damper 24 and the suspension spring 26 are expanded and contracted by road surface unevenness or the like, the drive shaft 27 also moves up and down accordingly, but the opening 16a of the splash guard 16 has a predetermined size. Therefore, the drive shaft 27 does not interfere with the opening 16a.

  Even if the wheel W splashes the splash of muddy water or the like into the wheel house 12 as the vehicle travels, the opening 16a of the splash guard 16 is covered with the boot 30, so that the splash passes through the opening 16a in the engine room. 11 can be prevented from entering the inside of the engine room 11 and the mounted object in the engine room 11 can be prevented from being soiled. Even if the drive shaft 27 moves relative to the opening 16a of the splash guard 16, the boot 30 is allowed to move due to elastic deformation of the boot 30.

  Further, when the cooling air introduced into the engine room 11 from the front grill or the like passes through the opening 16a of the splash guard 16 and flows into the wheel house 12, there is a problem that the air resistance of the vehicle body increases. According to the embodiment, since the boot 30 covers the opening 16a and prevents the cooling air from flowing out, an increase in the air resistance of the vehicle body can be prevented.

  Further, the boot 30 in the wheel house 12 is contaminated with the splash splashed by the wheel W, but the boot 30 is made of rubber and has a smooth surface. Splash is less likely to stick and is easier to clean than a splash or brush-like splash guard.

  Next, a second embodiment of the present invention will be described with reference to FIG.

  In the second embodiment, a tie rod 41 extending from a steering device such as a steering gear box provided in the engine room 11 penetrates the opening 16b of the splash guard 16 and is integrally formed with the knuckle 23. It is connected to the ball joint 42 at the tip. Therefore, when the tie rod 41 is pushed and pulled by the steering device, the wheel W is steered right and left together with the knuckle 23.

  As the suspension 18 moves up and down, the knuckle 23 and the tie rod 41 also move up and down, so that the opening 16b of the splash guard 16 through which the tie rod 41 passes is formed to a predetermined size. A tie rod 41 passes through the center of the outer end of a rubber boot 43 having an inner end outer peripheral portion coupled to the opening 16b of the splash guard 16, and the tie rod 41 is fixed to the boot 43 with clips 44 and 45 at the penetrating portion. Is done.

  Next, the operation of the second embodiment of the present invention having the above configuration will be described.

  When the wheel W bumps and rebounds together with the knuckle 23 while the damper 24 and the suspension spring 26 are expanded and contracted by the unevenness of the road surface, the tie rod 41 also moves up and down accordingly, but the opening 16b of the splash guard 16 has a predetermined size. Therefore, the tie rod 41 does not interfere with the opening 16b.

  Even if the wheel W splashes the splash of muddy water into the wheel house 12 as the vehicle travels, the opening 16b of the splash guard 16 is covered with the boot 43, so that the splash passes through the opening 16b into the engine room. 11 can be prevented from entering the inside of the engine room 11 and the mounted object in the engine room 11 can be prevented from being soiled. Even if the tie rod 41 moves relative to the opening 16b of the splash guard 16, the boot 43 is elastically deformed to allow the tie rod 41 to move.

  Further, when the cooling air introduced into the engine room 11 from the front grill or the like passes through the opening 16b of the splash guard 16 and flows into the wheel house 12, there is a problem that the air resistance of the vehicle body increases. According to the embodiment, since the boot 43 covers the opening 16b and prevents the cooling air from flowing out, an increase in the air resistance of the vehicle body can be prevented.

  Further, the boot 43 in the wheel house 12 is contaminated with the splash splashed by the wheel W, but the boot 43 is made of rubber and has a smooth surface. Splash is less likely to stick and is easier to clean than a splash or brush-like splash guard.

  The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

  For example, in combination with the first and second embodiments, the boots 30 and 43 may be provided on the drive shaft 27 and the tie rod 41 penetrating the splash guard 16, respectively, or the boots common to the drive shaft 27 and the tie rod 41 may be provided. May be provided.

  In the second embodiment, the tie rod 41 is fixed to the center of the boot 43, but the tie rod 41 may be slidably penetrated through the boot 43.

  The structure of the suspension 18 is not limited to the strut type of the embodiment.
