The invention relates to a road friction coefficient testing vehicle double-wheel driving friction coefficient testing device, which is structurally characterized in that wheels on two sides are respectively connected with the outer end of a transmission shaft, the inner ends of the transmission shafts on two sides are respectively connected with a one-way transmission mechanism, and the outer sides of the one-way transmission mechanisms on two sides are matched and connected with the inner side of a first transmission wheel of the same first transmission wheel; and the first transmission wheel is in transmission connection with a transmission chain, the transmission chain is in transmission connection with a second transmission wheel, the second transmission wheel is connected with a test wheel fixing shaft, and the test wheel fixing shaft is externally connected with a friction coefficient test wheel. The device has the advantages that the structural design is reasonable, the two separated transmission shafts are arranged to be matched with the one-way transmission mechanism to drive the first transmission wheel to drive the test wheel to rotate, test data distortion caused by suspension of the wheel on one side due to jolting during testing can be avoided, and the stability of a test result is guaranteed; and meanwhile, differential rotation of the two transmission shafts can be achieved through the one-way transmission mechanism, and the risk that the vehicle is out of control when the vehicle turns or deviates during testing is avoided.

    本发明是一种道路摩擦系数测试车双轮驱动摩擦系数测试装置,其结构是两侧车轮分别连接一个传动轴的外端,两侧传动轴内端分别连接一单向传动机构,两侧单向传动机构外侧与同一第一传动轮的第一传动轮内侧配合连接,第一传动轮传动连接传动链,传动链传动连接第二传动轮,第二传动轮连接测试轮固定轴,测试轮固定轴外接摩擦系数测试轮。本发明的优点:结构设计合理,设置两个分离的传动轴配合单向传动机构驱动第一传动轮带动测试轮转动,可避免测试时因颠簸使单侧轮子悬空导致的测试数据失真,保证测试结果的稳定性;同时单向传动机构可以实现两个传动轴的差速转动,避免测试时车辆转弯或跑偏时存在的车辆失控风险。
