Abstract
The invention relates to a vehicle steering device testing device having a real vehicle carrying capacity simulating function. The device includes a fixed frame which accepts a rack-gear box in a fixed manner; a first force joining device combined to an end part of a gear rod exposed from a side of the rack-gear box and exerting axial force or bending force in the axial cross direction on the gear rod; a second force joining device combined to the other end part of the gear rod exposed from the other side of the rack-gear box and exerting axial force or bending force in the axial cross direction on the gear rod. The device can simulate force transmitted to the gear rod of the steering device through wheels and a cross pull rod and tension, compression and bending forces due to wheel friction caused by vehicle load carrying and steering. Therefore, real vehicle testing (joint checking, normal operation check of gear rod, pinion and the rack-gear box) can be performed even without arranging the steering device on a real vehicle.
