Dual-front axle wheel axle parallel position adjustment method
InactiveCN101886910AGuaranteed parallelismReduce abnormal wear and tearUsing optical meansLaser transmitterSteering wheel
The invention provides a dual-front axle wheel axle parallel position adjustment method. The invention comprises the following steps: concentrically clamping on the wheel hub of the dual front axles of a vehicle by a special clamp, fully utilizing the span between the dual front axles, setting operation manners of a laser emitter and a corresponding target respectively, regulating a drag link between two wheel axles, and carrying out precise position on the wheel axles of the vehicle to be positioned by corresponding position manners of laser and the target. After the adjustment, parallelism of the dual-front axle wheel is secured, and all steering wheels upwards roll right ahead when the vehicle runs along a straight line, thereby effectively reducing abnormal wear and fuel consumption of tires, improving driving comfortableness, reducing waste of social resources and strengthening traffic safety.
