FIGS. 1 a and 1 b illustrate scale model vehicle, such as ascale mode 4×4 truck. The 4×4 scale model truck makes use of a standard transmission, as shown inFIG. 3 a. As shown inFIG. 3 a, the transmission (310) receives a rotational input from a prime mover, such as the engine. The transmission (310) transmits the rotational power from the engine to the rear differential (330) and front differential (370) thru the front drive shaft (360) and the rear drive shaft (350). Presently, higher order drive trains, such as 6×6 or greater are not currently available. - In one of many possible embodiments, an apparatus is provided that includes a six-wheel drive transmission drive train.

For example, according to one exemplary embodiment, a 6×6 scale mode vehicle is disclosed that makes use of a pass through differential.
- As used herein, the term “differential” shall be understood to mean a drive train component configured to receive a rotational input from a drive line, modify the ratio of the input rotation, and transmit the input rotation to one or more axles. Additionally, the term “differential” is meant to include any components, and/or sub-components of the drive train component including, but in no way limited to, spider gears that allow the one or more axles to rotate at differing velocities.

- According to one exemplary embodiment, the 6×6 scale model vehicle is much more stable climbing and ascending hills due to its longer wheel base and the added traction of two more tires. Such a vehicle may be more stable in the corners and offer added traction for acceleration and braking while cornering. The exemplary scale model vehicle is easier to control in the air while jumping due to its longer wheelbase and additional gyroscopic effect of having two additional wheels and tires. For example, a 6×6 scale model vehicle will climb over objects such as rocks, mud, sand, snow and others much better than the 4×4 because of the added traction and stability of having six wheels.

FIGS. 2 a and 2 b illustrate a scale model vehicle having six-wheel drive (6×6). In particular, as will be discussed in more detail below, the scale model vehicle includes a thru-differential. In particular, as will be discussed in more detail below, the thru-differential allows a standard 4×4 scale model vehicle to be converted into a higher order drive train transmission configuration, such as a 6×6 (six wheel drive) transmission drive train. - In particular, as shown in
FIG. 3 a, a standard configuration includes a rear differential (330). As shown inFIG. 3 b, a thru differential (320) may be added, with associated hardware, between the transmission (310) and the rear differential to form a 6×6 (six wheel drive) transmission drive train. The 6×6 may then be incorporated with wheels and other parts to form a 6×6 scale model vehicle, as shown inFIGS. 2 a and 2 b. According to the embodiment shown inFIGS. 2 a and 2 b, the thru-differential (320) would be coupled to the forward pair of rear wheels while the rear differential (330) would be coupled the rearward paid of rear wheels. -
FIG. 4 a shows the thru differential (320) and the exterior parts according to one exemplary embodiment. As shown inFIG. 4 a, the thru-differential (320) includes an input coupling (400), output coupling (410), axle drive coupling (420) and differential case (430). The input coupling (400) receives a rotational input from a prime mover, such as engine (310;FIG. 3 b). The prime mover may be any suitable type, including without limitation, an internal combustion type engine as shown, a battery or electric motor, or any other type of prime mover suitable for use with scale model vehicles. -
FIG. 4 b shows a cross sectional view of the thru differential (320). In particular, as show inFIG. 4 b, the thru-differential further illustrates the input coupling (400), the output coupling (410), the axle drive coupling (420), and the differential case (430).FIG. 4 c further illustrates pinion shaft bearings (440 & 450), a pinion drive input gear (490), a pinion output gear (460), and a common ring gear (470). The common ring gear (470) is used by both the pinion input gear (490) and the pinion output gear (460).FIG. 4 b also illustrates a differential housing (480). - The input coupling (400) is located on a common shaft with the pinion input gear (490) such that as the input coupling (400) is driven, the pinion input gear (490) is driven as well. The pinion input gear (490) is coupled to the common ring gear (470). Thus, as the pinion input gear (490) is driven, the pinion input gear (490) drives the common ring gear (470). The common ring gear (470) is on a common shaft with the axle drive couplings (420), such that as the common ring gear (470) rotates, the axle drive couplings (420) also rotate. If the axle drive couplings (420) are coupled to wheels, then those wheels are driven.
- As the common ring gear (470) rotates, the common ring gear (470) also drives the output coupling (410) through the pinion output gear (460). The output coupling (410) may be coupled to a rear differential (330). The rear differential (330) would then drive wheels coupled thereto, as is known. Thus, the thru-differential (320) receives an input from a prime mover. The thru-differential transmits the input to drive couplings and an output coupling to thereby provide rotational force for four or more wheels.
- The 6-wheel drive radio controlled truck has shown to be superior in almost all running conditions in both off road and on road environments. The thru differential (320) is what makes this step up from a 4-wheel drive to a 6-wheel drive economical, reliable and simple.
