Abstract
A transmission for a dune buggy has a transaxle, a transmission gear assembly, a forward bevel gear, a reverse bevel gear, a counterrotation bevel gear, a sleeve and a gear shifting lever assembly. The transmission gear assembly is mounted around the transaxle and is rotated by a motor in the dune buggy. The forward and reverse bevel gears are mounted rotatably around the transaxle. The forward bevel gear connects to the transmission gear assembly. The counterrotation bevel gear meshes with the forward and reverse bevel gears. The sleeve is mounted securely on the transaxle, slides longitudinally on the transaxle and selectively engages the forward or reverse bevel gears. The gear shifting lever assembly connects to the sleeve. Moving the gear shifting lever moves the sleeve.
Claims8
A transmission for a dune buggy comprising
- a transaxle adapted to be attached to two drive wheels of the dune buggy;
- a transmission gear assembly mounted rotatably around the transaxle, adapted to be rotated by a motor of the dune buggy and having
- an outer gear mounted rotatably around the transaxle;
- and
- an inner gear connecting securely to and rotated by the outer gear and mounted rotatably around the transaxle;
- a casing mounted around the transaxle and having
- a first opening;
- and
- a second opening;
- a forward bevel gear mounted rotatably around the transaxle in the casing near the first opening and having
- an inner end;
- a gear end;
- an outer extension protruding from the first opening in the casing and connecting to and rotated by the inner gear of the transmission gear assembly;
- and
- a recessed forward drive gear formed in the inner end of the forward bevel gear;
- a reverse bevel gear mounted rotatably around the transaxle in the casing near the second opening, being a counterrotating gear to the forward bevel gear and having
- an inner end;
- a gear end;
- and
- a recessed reverse drive gear formed in the inner end of the reverse bevel gear;
- a counterrotation bevel gear mounted rotatably in the casing and meshing with the gear ends of the forward and reverse bevel gears;
- a sleeve mounted on the transaxle in the casing, sliding longitudinally on the transaxle, selectively engaging one of the recessed forward drive gear and the recessed reverse drive gear and having
- an inner surface;
- an outer surface;
- a forward end;
- a reverse end;
- a forward gear formed on the forward end of the sleeve and selectively engaging the recessed forward drive gear of the forward bevel gear to drive the transaxle in a forward direction;
- and
- a reverse gear formed on the reverse end of the sleeve and selectively engaging the recessed reverse drive gear of the reverse bevel gear to drive the transaxle in a reverse direction;
- and
- a gear shifting lever assembly connecting to and pushing the sleeve to move and protruding from the casing.
