Claims

[Claim for Utility Model Registration] The tip of a torsion bar, one end of which is fixed to an input shaft connected to a steering wheel, is fixed to a pinion shaft that engages an output shaft connected to a steering wheel, and the relative position of the input shaft and output shaft is fixed. The hydraulic pressure is controlled by angular displacement to control the power assist force.Multiple through holes are provided in the radial direction of the pinion shaft, each plunger is slidably inserted into the hole, and the tip of the plunger is inserted into the outer circumference of the input shaft. Hydraulic pan-steering that fits into the vertical groove and moves the plunger to one side using hydraulic pressure according to the vehicle speed number to reduce the relative angular displacement between the input shaft and output shaft, thereby reducing the power assist force.

. O Scope of Utility Model Registration Claim □The tip of a torsion bar, one end of which is fixed to an input shaft connected to a steering wheel, is fixed to a pinion shaft engaged with an output shaft connected to a steering wheel, and the relative position of the input shaft and output shaft is fixed. The hydraulic pressure is controlled by angular displacement to control the power assist force. 5. A plurality of through holes are provided in the radial direction of the pinion shaft, and plungers are slidably inserted into each hole, and the tip of the plunger is inserted into the outer circumference of the input shaft. A hydraulic power steering system that fits into a longitudinal groove and presses the plunger inward using hydraulic pressure according to the vehicle speed, reducing the relative angular displacement between the input shaft and output shaft, thereby reducing the power arrest force. A variable steering force device for a hydraulic power steering device in which the spherical head at the tip of the plunger is slightly eccentric to the plunger axis. The following correction will be made: The "tonion bar" described in the 3rd to 2nd lines from the bottom of page 5 of the specification and the 4th line of page 6 of the specification will be corrected to "torsion bar."
