  • Patent number: 7416264
    Abstract: A wheel adjusting device can adjust separately the wheel angles of left and right wheels. A judgment portion which determines whether vehicle braking is to be permitted or not based on the driving state of the vehicle. A control portion controls the wheel adjusting device. More specifically, under conditions where the vehicle braking is permitted by the judgment portion, the control portion defines the wheel angles of the left and right wheels to be in opposite phase and adjusts the wheel angles in accordance with the braking force to be applied to the left and right wheels.

  • Patent number: 7334805
    Abstract: Disclosed herein is a wheel angle adjustment apparatus for automobile suspension systems. The wheel angle adjustment apparatus of the present invention has a structure such that upper, lower, left and right gaps between a spindle bracket and a wheel bracket are changed by tightening or loosening a plurality of locking bolts that couples the spindle bracket and the wheel bracket together. Therefore, toe and camber angles of each wheel are easily adjusted by tightening or loosening the locking bolts. In particular, when the present invention is used in a suspension system such as a torsion beam suspension system which has a structure such that a wheel alignment using a connection part provided between the automobile body and wheels is impossible, the wheels are easily aligned merely by adjusting the gap between the spindle bracket and the wheel bracket.

    Abstract: An apparatus for measuring the dynamic characteristics of the vehicle wheel alignment in non-contact fashion with high accuracy is disclosed. A laser light source (4) emits a laser beam of a predetermined geometric pattern toward the wheel side surface. A laser beam control device (6) controls the width of the laser beam in such a manner as to be radiated only in a predetermined range of the wheel side surface. Two laser light sources (120), (121) emit non-parallel laser beams. A photdetecting device (122) receives the two laser beams and converts them to two corresponding image data. A processing unit calculates the distance between the two images based on the two image data and calculates the wheel alignment based on the same distance.

    Abstract: A steering device for an industrial vehicle such as forklift. A pair of knuckle arms are rotatably supported at the ends of a rear axle. Each knuckle arm supports a rear wheel. A cylinder located in the rear axle includes an actuator rod. A pair of tie-rods couple the ends of the actuator rod to the knuckle arms. A toe angle adjusting mechanism is located between one end of the actuator rod and the corresponding tie-rod. The toe angle adjusting mechanism includes an adjuster pin having an eccentric shaft. The toe angle of the rear wheel that does not have the toe angle adjusting mechanism is adjusted by changing the neutral position of the actuator rod relative to the cylinder. Thereafter, the toe angle of the other rear wheel is adjusted by the toe angle adjusting mechanism, which facilitates adjustment of the toe angle of the wheels. The location and number of angle adjusting mechanisms are varied in alternate embodiments.
