Abstract  This paper studies the symmetry of Lagrangians of nonholonomic systems of non-Chetaev's type. First, the definition and the criterion of the symmetry of the system are given. Secondly, it obtains the condition under which there exists a conserved quantity and the form of the conserved quantity. Finally, an example is shown to illustrate the application of the result.
Keywords:  nonholonomic system      non-Chetaev's type constraint      symmetry of Lagrangians      conserved quantity
