Abstract
Abstract A motorized two-wheeled vehicle is disclosed having a power transmission casing which comprises a main casing body (6) extending rearwardly laterally of the body from one side of the engine (4) of the vehicle to one side of the driven rear ground wheel (3) of the vehicle and rotatably supporting a wheel axle (5) of the rear wheel. The main body has fitted to it in liquid-tight manner a reduction gear mechanism cover (10) so that a reduction gear mechanism (9) contained in this part of the main body (6) can be immersed in oil. Also fitted to the main body is a V-belt transmission cover (16) and a V-belt transmission (15) of dry type is contained in this part of the main body (6). The casing as a whole is small-sized and as the reduction gear mechanism is immersed in lubricating oil it is always well lubricated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
205 words
A motorized two-wheeled vehicle having a V-belt transmission mechanism and a reduction gear mechanism interposed between the motor of the vehicle and the rear driven ground wheel of the vehicle; characterised in that the vehicle has a power tranmission casing comprising a main casing body (6) extending laterally of the body from one side of the motor(4) of the vehicle rearwardly to one side of the rear ground wheel (3) of the vehicle and rotatably supporting a wheel axle (5) of the rear ground wheel, a reduction gear mechanism cover (1) fitted to a rear portion of the casing body in light-tight manner, and a V-belt transmission cover (16) fitted to a front portion of the casing body; the reduction gear mechanism (9), comprising the wheel axle (5), an input shaft (7) and a gear train (8) connecting the axle and the input shaft, being covered by the reduction gear mechanism cover (10); and the V-belt transmission (15), comprising a pulley (11) on the input shaft (7) externally of the reduction gear mechanism cover (10), a pulley (13) on an output shaft (12) of the motor (4) and a V-belt (14) running around these two pulleys (11,13), being covered by the V-belt transmission cover (16).
Claim 2
Dependent Claim
205 words
A motorized two-wheeled vehicle having a V-belt transmission mechanism and a reduction gear mechanism interposed between the motor of the vehicle and the rear driven ground wheel of the vehicle; characterised in that the vehicle has a power tranmission casing comprising a main casing body (6) extending laterally of the body from one side of the motor(4) of the vehicle rearwardly to one side of the rear ground wheel (3) of the vehicle and rotatably supporting a wheel axle (5) of the rear ground wheel, a reduction gear mechanism cover (1) fitted to a rear portion of the casing body in light-tight manner, and a V-belt transmission cover (16) fitted to a front portion of the casing body; the reduction gear mechanism (9), comprising the wheel axle (5), an input shaft (7) and a gear train (8) connecting the axle and the input shaft, being covered by the reduction gear mechanism cover (10); and the V-belt transmission (15), comprising a pulley (11) on the input shaft (7) externally of the reduction gear mechanism cover (10), a pulley (13) on an output shaft (12) of the motor (4) and a V-belt (14) running around these two pulleys (11,13), being covered by the V-belt transmission cover (16).
Claim 3
Dependent Claim
29 words
A vehicle as claimed in claim 1, wherein the main casing body (6) is fast with the motor (4) so as to constitute with the motor a power unit.
Claim 4
Dependent Claim
36 words
A vehicle as claimed in claim 1 or 2, wherein the reduction gear mechanism cover (10) has a portion extending rearwards beyond the V-belt transmission cover (16) and provided with oil filler and drain openings (19,20).
Claim 5
Dependent Claim
45 words
A vehicle as claimed in claim 3, wherein the main.casing body (6) is internally divided-in liquid-tight manner into two chambers (A, B) respectively closed by the V-belt transmission cover (16) and the reduction gear mechanism cover (10), the V-belt transmission (15) being of dry type.
Claim 6
Dependent Claim
25 words
A vehicle as claimed in claim 4, wherein the V-belt transmission cover (16) is applied directly to the main casing body (6) without interposed packing.
