Abstract: In a steer-by-wire steering control device for a vehicle using a model following control based on yaw rate or lateral acceleration, the target steering angle(s) of front wheels and/or rear wheels (Sfbs, Srbs) are corrected according a roll rate (Rre) of the vehicle which may be either detected or estimated from a lateral acceleration or yaw rate. Thereby, the roll rate gain can be reduced, and the damping property and response property of the yaw rate can be improved.

Abstract: A wheel suspension system for automobiles includes a control arm having a pair of front and rear inner ends and an outer end connected to a knuckle rotatably supporting a wheel. The inner ends are pivotally mounted to a vehicle body. At least one of the inner ends of the control arm is formed into bifurcated arms arranged longitudinally of the vehicle body. One of the bifurcated arms is rectilinearly integrally connected with the other inner end through a connection. A bolt for supporting the bifurcated arms at opposite ends is carried at a middle portion thereof on the vehicle body through a rubber bush. This allows the inner ends of the control arms and a section therebetween to be enhanced in rigidity, thereby enabling reductions in wall thickness and weight of the control arms.

Abstract: A pair of upper and lower radius rods are connected at their rear ends to upper and lower portions of a swingable link system which includes a knuckle and upper and lower control arms, and have their front ends interconnected and pivotally connected to a vehicle body through an elastic support member for vertical swinging movement, and an included angle between two straight lines connecting the pivoted point and respective rear end of the radius rods is set to be an acute angle. This enables application of a force to the elastic support member between the radius rods and the vehicle body to be distinguished from (a) when a braking force has been applied to the wheel and (b) when the longitudinal load has been applied to a central portion of the wheel.

Abstract: A hydrolyzed ethylene-vinyl acetate copolymer having an ethylene content of 20 to 60% by mole and a defree of hydrolysis in the vinyl acetate component of at least 95% by mole, having an ash content of not more than 20 ppm and an alkali metal content of not more than 5 ppm, and having a ratio of the melt viscosity at 220.degree. C. after maintaining the copolymer at 220.degree. C. for 60 minutes to the melt viscosity at 220.degree. C. after maintaining the copolymer at 220.degree. C. for 5 minutes of 1.0 to 1.5. The hydrolyzed copolymer of the invention can give the films whose gas impermeability is not lowered even at high humidity, and is applicable to long-run molding.

Abstract: A wheel suspension system for automobiles, which comprises a pair of upper and lower control arms connected at their leading ends to a knuckle for carrying a wheel and having base ends each of which is vertically swingably pivoted respectively at front and rear spaced positions to a vehicle body, wherein a pair of upper and lower support arms are projectingly mounted on a vertical support shaft which is carried on the vehicle body through elastic members, and either of front and rear portions of respective base ends of the upper and lower control arms are connected respectively to the upper and lower support arms. This makes it possible to assure a larger caster rigidity during braking while providing a large longitudinal compliance.

Either the radius rod or the stabilizer is coupled to one of upper and lower surfaces of the lower arm, the other being inserted in the attachment aperture and coupled to the lower arm therein.

Abstract: A suspension for vehicles. The suspension includes a knuckle arm for supporting a steerable road wheel of the vehicle, an upper arm jointed at one end with the upper end of the knuckle arm and pivotably connected at the other end to a body frame of the vehicle, a lower arm jointed at one end with the lower end of the knuckle arm and pivotably connected at the other end to the body frame, and a shock absorber cooperating with the upper arm and the lower arm for suspending, through the knuckle arm, the steerable road wheel from the body frame. The upper arm has its position displaced longitudinally of the vehicle with a space left, and the shock absorber is disposed in the space obtained by the longitudinal displacement of the upper arm.

Abstract: A power transmission device for a front-engine front-drive car having right and left drive shafts different in length from each other. The turning moments applied to right and left front wheels when the car is accelerated are made equal to each other by making the descent angles of the drive shafts respectively substantially equal to each other. Moreover, the allowable steering angle ranges of the right and left front wheels can be widened by allowing the angles made between the right and left drive shafts and the common axis of the right and left front wheels respectively to be substantially equal to each other as viewed in a plan view.
