Abstract
The symmetries and conserved quantities for the systems with unilateral holonomic constraints were studied.The differential equations of motion of the systems were established.Under the point symmetric transformations of the coordinates and time,the definition of Lie symmetry of the system was given, and a new type of conserved quantities called Lutzky conserved quantities,which is directly deduced from Lie symmetries of the system,was obtained.As special cases,the Lutzky conserved quantities for the system with remainder coordinates,the non-conservative system and the Lagrange system,were given.An example was given to illustrate the application of the results.
