摘要： [Problem] To restrain a retracting stabilizer from interfering with an assist motor located rearward thereof and ensure energy absorption by a subframe.
[Means for Solution] A vehicle front structure includes: an engine 10; a steering rack 61, 61x disposed frontward of the engine 10; an assist motor 68 for power steering disposed frontward of the steering rack 61, 61x; a suspension stabilizer 70 disposed frontward of the assist motor 68; and a subframe 30 mounted with the stabilizer 70, wherein the stabilizer 70 frontward of the assist motor 68 is disposed offset from the assist motor 68 in an up-down direction so as not to overlap the assist motor 68 in vehicle front view.-

摘要： [Problem] An object is to provide a front suspension apparatus in which a front side of a suspension arm can be cut off from a subframe at the time of a small overlap collision without causing the complication of the structure and the formability.
[Means for Solution] A front suspension apparatus in which a lower arm 52 from which a front wheel is suspended is provided, and a front arm portion 53 and a rear arm portion 54 of the lower arm 52 are axially supported by axially supporting portions of a subframe 30 is characterized in that an axially supporting portion 59 of the front arm portion 53 is joined to the subframe 30 at a joined portion extending in a vehicle width direction, a joined portion extending in an up-down direction, and a joined portion extending in a front-rear direction, and a joining strength of a joined portion k in the front-rear direction is lower than a joining strength of the joined portion in the up-down direction.-

摘要： [Problem] Provided is a subframe structure of a front suspension that leads a subframe and a vehicle driving apparatus to the lower side after the separation of a rear portion of the subframe due to a frontal collision without increasing the weight and the number of parts even when the rear portion of the subframe is not mounted on an inclined portion of a body.
[Means for Solution] The subframe structure of the front suspension is characterized in that a subframe 30 that supports a vehicle driving apparatus in a mounting manner is provided, a rear portion 62 of the subframe 30 is mounted on a lower portion of a vehicle body 9 via a fastening member 76, fastening between the subframe 30 and the fastening member 76 is configured such that the rear portion of the subframe 30 is separated when a collision load to a vehicle rear side is applied to the subframe 30, an a leading guide portion 62d that abuts against the fastening member 76 and leads the subframe 30 to a lower side after separation from the fastening member 76 is integrally formed on the rear portion of the subframe 30.-

摘要： The bushing (50) includes an outer cylinder (60), an inner cylinder (70), and an elastic body (80) therebetween. The outer cylinder (60) has a central recess portion (62) recessed from the inner peripheral surface (61) in the radial direction at the central portion (63) in the axial direction, and the thickness of both end portions (64) is thicker than the thickness of the central portion (63). The central recess portion (62) is formed in a curved shape or having a curved and a straight shape. The inner cylinder (70) has a central convex portion (72) swelling from the outer peripheral surface (71) in the radial direction at a position corresponding to the central recess portion (62). The maximum outer diameter (D2) of the central convex portion (72) is larger than the minimum inner diameter (Dl) of the inner peripheral surface (61) of the outer cylinder (60).

摘要： [Problem]
To achieve large energy absorption by a subframe structure by deforming front-rear frames into a Z shape in vehicle side view in the event of a front-end collision.
[Means for Solution]
The subframe structure includes: a pair of front-rear frames 31 each mounted with a lower arm 21; and a transverse member 32 connecting front portions of the front-rear frames 31, wherein the front-rear frames 31 each include a rear horizontal portion 39a, an inclined portion 39b extending frontward and substantially upward from a front end of the rear horizontal portion 39a, and a front horizontal portion 39c extending frontward from a front end of the inclined portion 39b, the transverse member 32 is jointed at first and second ends thereof to the front horizontal portions 39c respectively corresponding to the first and second ends, a rear end 39f of the front horizontal portion 39c is configured to be positioned frontward of a front end 10f of an engine 10, and the front-rear frames 31 are configured to deform into a Z shape in vehicle side view in an event of a front-end collision and thereby absorbing energy of the front-end collision.-

摘要： The bushing (50) includes an outer cylinder (60), an inner cylinder (70), and an elastic body (80) therebetween. The outer cylinder (60) has a central recess portion (62) formed in a curved shape. The inner cylinder (70) has a central convex portion (72) being formed in a curved shape. A distance between a vertex (V1) of the central recess portion (62) and the vertex (V2) of the central convex portion (72) is smaller than a distance between a point (S1) other than the vertex (V1) of the central recess portion (62) and a point (S2) at which a straight line extending from the point (S1) other than the vertex (V1) of the central recess portion (62) to an intersection point of the perpendicular line and the axis (x) of the inner cylinder (70) intersects the central convex portion (72).
