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.
Description
technical field [0001] The invention relates to a two-wheel drive friction coefficient testing device of a road friction coefficient testing vehicle. Background technique [0002] The road friction coefficient test vehicle is generally used to output test reports according to the format of different regions, providing accurate daily road surface lateral friction coefficient values, which can be used as part of road maintenance and provide basis for it. The road friction coefficient test vehicle can be divided into one-piece and split-type. The friction coefficient test device of the one-piece road friction coefficient test vehicle is integrated inside the small motor vehicle, and the split type is generally a small trailer towed at the rear of the small motor vehicle. [0003] In the prior art, the integrated road friction coefficient test vehicle is driven by a single-side wheel connection. During the test, the one-side wheel will be suspended due to bumps, resulting in dis...
