Abstract: A brake system in a buggy includes first and second brake shafts which are disposed on one side of the left and right differential output shafts in a longitudinal direction of the vehicle and in parallel to the left and right differential output shafts and which are driven at increased speeds by the left and right differential output shafts. The first and second brake shafts and the first and second brakes are accommodated within a reduction case, so that the first and second brakes are cooled by lubricating oil within the reduction case. Thus, the brake system in the buggy can be mounted at a high level above the ground; is excellent in dustproof and waterproof properties; is cooled satisfactorily, and moreover, is capable of reliably braking left and right wheels simultaneously.
Abstract: A brake for a buggy vehicle includes a plurality of rotatable friction brake plates which are axially slidably and relatively non-rotatably coupled to the input shaft of a reduction device spline-coupled to a propelling shaft, a plurality of stationary friction brake plates alternately superposed with the rotatable friction brake plates, a brake non-rotatable housing which houses the group of the rotatable and stationary friction brake plates therein and which supports said stationary friction brake plates for axially sliding movement and against rotation, a pressure-receiving portion provided in the brake housing to carry one side of the group of the rotatable and stationary friction brake plates, and an operating device capable of urging the other side of the group of the rotatable and stationary friction brake plates against the pressure receiving portion.
Abstract: A wet multi-plate clutch includes a clutch outer connected to an input member, a clutch inner relatively rotatably disposed within the clutch outer and connected to an output member, a plurality of first friction plates axially slidably spline-fitted to an inner peripheral wall of the clutch outer and accommodated within the clutch outer, a plurality of second friction plates axially slidably spline-fitted to an outer peripheral wall of the clutch inner and superposed one on another alternately with the first friction plates, and a clamping device capable of clamping groups of the first and second friction plates axially to bring adjacent ones of the first and second friction plates into friction engagement with each other. In this wet multi-plate clutch, stopper devices are mounted at opposite ends of a spline groove in the clutch outer for limiting the distance of sliding movement of spline teeth of the group of the first friction plates.
