Abstract

Abstract A self-propelled, four-wheeled vehicle is disclosed in which one of the rear wheels is motor driven, and the other rear wheel is arranged to be free-wheeling. Depending upon the selected drive torque transmitted to the single driven wheel, the vehicle either moves straight and level, or performs a wheel stand while moving circularly. A user can select the desired vehicle motion from a remote location.

Total Claims: 6
Claim 1
Independent Claim 148 words
A stunt vehicle comprising a vehicle body having a forward portion and a rearward portion; a pair of wheels rotatably mounted to the rearward portion of said body; motor drive means coupled to one of said wheels for driving said one wheel with a selected torque, the other wheel being free to idle; and control means coupled to said motor drive means for actuating said motor drive means to provide a selected one of a first driving torque and a greater second driving torque to said one wheel; the center of gravity of said vehicle being located so that said body is level when propelled by said one wheel when said first driving torque is selected, and the forward portion of said vehicle body is raised upwardly and said vehicle is circularly propelled by said one wheel about said other wheel when said second driving torque is selected.
Claim 2
Dependent Claim 148 words
A stunt vehicle comprising a vehicle body having a forward portion and a rearward portion; a pair of wheels rotatably mounted to the rearward portion of said body; motor drive means coupled to one of said wheels for driving said one wheel with a selected torque, the other wheel being free to idle; and control means coupled to said motor drive means for actuating said motor drive means to provide a selected one of a first driving torque and a greater second driving torque to said one wheel; the center of gravity of said vehicle being located so that said body is level when propelled by said one wheel when said first driving torque is selected, and the forward portion of said vehicle body is raised upwardly and said vehicle is circularly propelled by said one wheel about said other wheel when said second driving torque is selected.
Claim 3
Dependent Claim 45 words
A vehicle according to claim 1, further including at least one front wheel mounted for rotation to the forward portion of said body so that said vehicle body is guided by said front wheel and said rear wheels when said first driving torque is selected.
Claim 4
Dependent Claim 29 words
A vehicle according to claim 2, further including selector means remote from said vehicle for enabling a user to select either one of said first and second driving torques.
Claim 5
Dependent Claim 53 words
A vehicle according to claim 1, further including another pair of wheels mounted to the forward portion of said body for rotation about a common axis transverse to said body so that said vehicle body moves in a straight path on both said pairs of wheels when said first driving torque is selected.
Claim 6
Dependent Claim 73 words
A vehicle according to claim 1, wherein said motor drive means includes an axle shaft having a pinion gear axially joined thereto intermediate the ends of said shaft, said one wheel being fixedly joined to one end of said shaft and said other wheel being mounted for pivotal movement about the other end of said shaft, and a motor mounted to said body having a driving gear for operatively engaging said pinion gear.
