Remote control two-wheel model

Abstract

An RC two-wheel model is composed of a frame assembly, a front wheel assembly, and a rear wheel assembly. The frame assembly includes a frame body and a transmission set mounted to the frame body. The front wheel assembly includes a front wheel frame and a front wheel. The front wheel frame is rotatably mounted to the frame body at a top end thereof and has a pair of front forks. The front wheel is rotatably connected with a bottom end of the two front forks. The rear wheel assembly includes a rear wheel frame connected with the frame body, and a rear wheel rotatably connected with the rear wheel frame and the transmission set. Therefore, the above design can simplify and expedite the performance calibration, assembly, and repair of the RC two-wheel model.

         2 . The RC two-wheel model as defined in  claim 1 , wherein the frame body includes a multi-position portion extending along an arc-shaped course and connected with the front wheel frame. 
     
     
         3 . The RC two-wheel model as defined in  claim 2 , wherein the front wheel frame further comprises an upper limiter, a lower limiter, and a locating member, the locating member having its front end be pivoted between the upper and lower limiters and having its rear end be pivoted to the multi-position portion, each of the front forks being inserted through the upper and lower limiters and having its front end be fixed to the upper limiter, whereby the angle between the two front forks and the ground can be adjusted without any change of the wheelbase between the front wheel and the rear wheel. 
     
     
         4 . The RC two-wheel model as defined in  claim 3 , wherein the multi-position portion comprises at least two pairs of first locating holes; the locating member comprises a second locating hole; the front wheel frame comprises two fastening pieces which can be selectively inserted through one of the first locating holes to be fixed to the second locating hole. 
     
     
         5 . The RC two-wheel model as defined in  claim 3 , wherein the locating member comprises an axial portion and two opposite through holes, the axial portion having its two ends be inserted into one of the through holes to be movable within the two through holes; the front wheel frame comprises a fastening pin fixed to the frame body and inserted through the axial portion. 
     
     
         6 . The RC two-wheel model as defined in  claim 3 , wherein the front wheel assembly further comprises a steering server mounted in the locating member, a pivoting member pivoted to the steering server, and a steering linking member connected between the pivoting member and the upper limiter. 
     
     
         7 . The RC two-wheel model as defined in  claim 1 , wherein the frame assembly comprises a base and a movable member, the movable member being movably mounted to the base; the transmission set comprises a motor, a gear shaft, a first driving gear, a second driving gear, a passive gear, and a chain, the motor being mounted to the movable member, the gear shaft being rotatably inserted through the movable member, the first driving gear connected with an end of the gear shaft, the passive gear being rotatably mounted between the rear wheel frame and the rear wheel, the chain engaging the second driving gear and the passive gear. 
     
     
         8 . The RC two-wheel model as defined in  claim 7 , wherein the base of the frame assembly further comprises at least one convex portion and at least one first through hole; the movable member of the frame assembly further comprises at least one second through hole and at least one fixing hole, the at least one convex portion being mounted to the at least one second through hole, the at least one first through hole communicating with the at least one fixing hole; the frame assembly further comprises at least one fastener inserted through the at least one first through hole to be fixed to the at least one fixing hole. 
     
     
         9 . The RC two-wheel model as defined in  claim 8 , wherein the at least one convex portion is one in number; the at least one first through hole is two in number; the at least one second through hole is one in number; the at least one fixing hole is two in number; the at least one fastener is two in number. 
     
     
         10 . The RC two-wheel model as defined in  claim 8 , wherein the at least one convex portion is two in number; the at least one first through hole is one in number; the at least one second through hole is two in number; the at least one fixing hole is one in number; the at least one fastener is one in number. 
     
     
         11 . The RC two-wheel model as defined in  claim 7 , wherein the movable member comprises a third through hole and at least one fourth through hole; the motor comprises an output shaft inserted through the third through hole to engage the first driving gear; the transmission set further comprises at least one fastener inserted through the fourth through hole to be fixed to the motor.
