DEVICE FOR ADJUSTING ANGLE OF REAR AXLE
First Claim
1. An active mounting apparatus for aligning an input shaft of a rear axle by actively adjusting a position angle, the apparatus comprising:
- a mounting bracket that is mounted on at least a portion of upper surface of a leaf spring;
a rotatable support member that is pivotally mounted in the mounting bracket;
a hydraulic cylinder that is connected to a portion of the rotatable support member and rotates the rotatable support member clockwise or counterclockwise;
a hydro supply unit that supplies or bypasses oil pressure to the hydraulic cylinder;
a suspension geometry measuring sensor that detects an up-and-down movement value of the rear axle; and
a control unit that receives the up-and-down measurement value from the suspension geometry measuring sensor, determines the position angle of the rotatable support member to make an output shaft of a transmission and the input shaft of the rear axle in a straight line, based on the up-and-down measurement value from the suspension geometry measuring sensor, and controls the hydro supply unit to supply an oil pressure to the hydraulic cylinder.

Abstract
The present invention provides an active mounting apparatus for adjusting an input shaft of a rear axle to make an output shaft of a transmission and the input shaft of the rear axle in a straight line. The apparatus includes a mounting bracket, a rotatable support member, a hydraulic cylinder, a hydro supply unit, a suspension geometry measuring sensor, and a control unit. The rotatable support members are rotatably mounted on mounting bracket. The hydraulic cylinder controlled by the control unit activates a clockwise or counterclockwise position angle of rotatable support member. Therefore, even though the rear axle is moved upward or downward due to the change in load during the driving of a vehicle, an output shaft of a transmission and an input shaft of the rear axle are always aligned with each other on one straight line so as to minimize vibration, noise, and the loss of power.
