本实用新型涉及一种普通乘用车白车身扭转刚度测试加载装置， 包括试验平台、 旋转T形梁、前悬架约束夹具、 后悬架约束夹具， 以及从上到下依次相连的延伸支架、 上铰链连接座、 力传感器、 加载器和底座， 延伸支架固设在旋转T形梁的水平梁一端， 上铰链连接座与延伸支架的固定点距离旋转T形梁的旋转轴的横向水平距离L为1000mm， 力传感器的上下两端的连接均为球铰，并具备力值显示功能， 加载器能在垂直方向上实现空间尺寸的稳定增大或缩小， 从而带动普通乘用车白车身绕旋转T形梁的旋转轴顺时针扭转或逆时针扭转。 适用于普通乘用车白车身及类似车型使用， 控制精度更高、 更简便、 加载方便、 力矩准确。

The utility model relates to a torsion stiffness test loading device for an ordinary passenger car body in white, which comprises a test platform, a rotating T-beam, a front suspension restraint fixture, a rear suspension restraint fixture, and an extension support, an upper hinge connection seat, a force sensor, a loader and a base connected from top to bottom. The extension support is fixed at one end of the horizontal beam of the rotating T-beam, The transverse horizontal distance L between the fixed point of the upper hinge connecting seat and the extension support and the rotation axis of the rotating T-beam is 1000mm. The connections at the upper and lower ends of the force sensor are spherical hinges and have the function of force value display. The loader can stably increase or reduce the space size in the vertical direction, so as to drive the ordinary passenger

Twist the BIW clockwise or counterclockwise around the rotation axis of the rotating T-beam. It is applicable to ordinary passenger car body in white and similar models, with higher control precision, easier loading and accurate torque.
