Abstract

DC60 (22/05/55) in order to provide a power unit for light vehicles which will cover many parts of gear shift mechanism and to provide increased strength to support the core spin the starter in power units for small vehicles, where at least part One of the shifting mechanisms, the C gear, is exposed on one side of the crankcase 11, the side cover 20 that contains part of the The gearshift mechanism C, which opens from the crankcase 11, is connected in Detachable appearance To the side wall of the crankcase 11, the kick starter 21 is supported by the side cover 20 and the crankcase 11. The starter pedal 22 is fixed. fit the part outer end of Kick starter 21 protruding from the side cover 20. The purpose is to provide a small vehicle power unit to cover. Several parts of the gear shifting mechanism and to provide increased strength to support the core spin the starter The way to solve the problem is in power units for small vehicles, where at least part One of the C gearshift mechanisms is exposed on one side of the crankcase 11. The side cover 20 contains part of the C gearshift mechanism, which opens out of the crankcase 11 is connected in. Detachable style to the side wall of the 11 crankcase, 21 kick starters, are supported by side covers 20 and crankcase 11, kick starter 22. Get a direct fixation to the part. The outer end of the kick starter 21 protruding from the side cover 20.

Claims (5)

Which has the characteristics The gearshift mechanism (C) consists of a shifting shaft (32), which is fitted in a sliding manner into the center of at least one piece of the input shaft. The transmission chamber (14) and the transmission shaft output shaft (15) from the side cover (20), which are to be selected. Causes one of the parts of the transmission gear unit (Ga-Gd) to operate in accordance with the sliding, spindle. Shift gears (42), which are supported in an angular motion, are on the side covers (20), arm Shifting gear (40), which is fixed on the shifting spindle (42) in the side cover (20) for shifting. Gear shift shaft (32) in response to the angular motion of the shifting spindle (42), and The shifting control assembly (54), which is externally connected to the shifting spindle (42). The side cover (20), the cassette joint (40) are positioned between the said shifting shaft (32) and the starter crankshaft (21). 2. A power unit for light vehicles according to claim 1, whose characteristics are The first and second side covers (20b, 20a) consist of the combined side covers (20), which provide a continuous surface. In the first and second side covers (20b, 20a) 3. The power unit for light vehicles according to claim 2, which is characterized by the aforementioned gearshift mechanism (C), consists of a shifting shaft (32) fitted in Scrollable style With the center of at least one A piece of the transmission shaft (14) and the transmission shaft (15) from the side cover (20), which will select one of the components of the transmission gear assembly (Ga - Gd) works in accordance with the shifting, shifting pivot (42), which is supported in an angular motion. Located on the side cover (20), cassette joint (40), which is fixed on the shifting spindle (42) in the side cover (20) for shifting the shifting shaft (32) in response to The angular movement of the shifting spindle (42), and the shifting control assembly (54), which are connected to the The shifting spindle (42) is located outside the side cover (20), the shift arm (40) is positioned between the shafts. Shifting gears (32) and starter pedals (21). 4. The light vehicle power unit in accordance with one of claim 1 to 3, which is characterized by the aforementioned kickstart pivot (21), is supported by three walls that include walls. One side of the second side cover (20a) and the two side walls of the crankcase (11). 5. A power unit for light vehicles according to claim 4, whose characteristics are A one-way clutch mechanism (61) has been placed in the crankcase (11) for transmitting the rotational power of the The crankshaft throws the starter (21) towards the crankshaft (13) in response to the kick start on the kick start arm (22), and the return spring (66, 67) is obtained. An arrangement is placed in a second side cover (20) to reverse the kick start shaft (21) in that direction to restore the kick start arm (22).
