Abstract
The utility model discloses a free clutch means of an engine, wherein, an initial gear (9) is arranged on a right crank shaft handle (4); an oil pump (1) and a friction clutch (2) are respectively arranged on the lateral faces of the initial gear (9); a driven gear (10) of the friction clutch (2) is meshed with the initial gear (9). The utility model is characterized in that: a drive gear (8) is sleeved at the lower part of a right crank shaft handle (4); a centrifugal block means is fixed at the upper part of the right crank shaft handle (4); the external housing of a centrifugal clutch is fixedly connected with the initial gear (9); transition gears (6) (7) connected by a shaft are arranged in the oil pump (1); the transition gear (6) is meshed with a large gear (5) and the transition gear (7) is meshed with the drive gear (8). The utility model has the advantages of double automatic and manual performance, simple operation, stable drive and comfortable ride when arranged inside the engine of a motorcycle.
Description
(1). technical field
The utility model belongs to motorcycle field, particularly a kind of free clutch is installed in the device in the motorcycle engine.
(2). background technique
Automatic clutch is installed in motorcycle engine, can be made in the process of moving variable block of motorcycle, deceleration, parking, have simple to operately, travel steadily, take advantage of the comfortable advantage of seat without the clutch brake handle.But owing to be subjected to the restriction of engine interior structure, this structure can only be used for the motorcycle engine of little discharge capacity.
(3). summary of the invention
The purpose of this utility model provides a kind of free engaging and disengaging gear of motor.It is installed in the motorcycle engine, has automatic, the dual performance of manual clutch concurrently, and simple to operate in addition, travel steadily, take advantage of the comfortable characteristics of seat.
For reaching above-mentioned purpose, the utility model is movably arranged on primary pinion on the right crankshaft handle, oil pump is installed in a side of primary pinion, friction clutch is installed in the opposite side of primary pinion, driven gear in the clutch and primary pinion engagement, it is characterized in that: driven gear is enclosed within the right handle of bent axle and is fixed on the bottom, and the centrifugal block assembly in the centrifugal clutch is fixed on the top of the right handle of bent axle, and its outer cover and primary pinion are connected; The transition gear that connects up and down with axle is set, described upward transition gear and gearwheel engagement, following transition gear and driven gear engagement in the oil pump.
Top at friction clutch can be provided with the manual clutch device.
The utility model is owing to right case and the part between the right case lid to motorcycle engine carries out the part change, make it become a kind of free clutch motor, therefore decapacitation is installed in the small-displacement engine of motorcycle, can also be installed in 125 milliliters and the above displacement motorcycle engine, can make motorcycle in the process of moving according to road conditions, variable block, deceleration, parking are freely selected whether to use the clutch brake handle, have simple to operate, travel steadily, take advantage of the comfortable advantage of seat.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is a structure diagram of the present utility model.
(5) embodiment
Referring to Fig. 1.Primary pinion 9 is installed on the right crankshaft handle 4 versatilely, oil pump 1 is installed in a side of primary pinion 9, friction clutch 2 is installed in the opposite side of primary pinion 9, driven gear 10 in the friction clutch 2 and primary pinion 9 engagements, be enclosed within driven gear 8 on the right handle 4 of bent axle and be fixed on its underpart, the right handle of the bent axle that clutch block 11 in the centrifugal clutch is fixed on 4 tops, its outer cover 3 is connected with primary pinion 9, and the part that centrifugal clutch is stretched out on the right handle of bent axle 4 tops injects in the oil channel hole of right case lid 12.The transition gear 6,7 that connects up and down with axle is set, gearwheel 5 engagements in transition gear 6 and the oil pump 1, transition gear 7 and driven gear 8 engagements in oil pump 1.
When handle 4 idle runnings of the bent axle right side, because of with the hard-wired centrifugal clutch in right handle 4 tops of bent axle in clutch block device 11 do not open, this moment, centrifugal clutch outer cover 3, primary pinion 9, friction clutch 2 were also motionless, i.e. engine idling operation, and motorcycle is running state not; When opening the throttle, engine speed raises gradually, open the inwall that contacts centrifugal clutch outer cover 3 gradually with on the centrifugal clutch that the right handle 4 of bent axle is connected centrifugal 11, constantly the frictional force that increases drives centrifugal clutch outer cover 3 gradually, primary pinion 9 rotates, primary pinion 9 drive driven gears 10 and friction clutch 2 and the motorcycle transmission system running that is connected with friction clutch 2, motorcycle just quickens to advance; Unclamp throttle, motor is reduced to idling immediately, the friction that centrifugal block assembly 11 on the centrifugal clutch breaks away from centrifugal clutch outer cover 3 inwalls, shrink back the original state before opening the throttle, centrifugal clutch outer cover 3, primary pinion 9 just stop operating, driven gear 10, friction clutch 2 stop operating, and friction clutch 2 stops the motorcycle transmission system transmission of power to being connected with friction clutch 2 simultaneously, and motorcycle halts.Because the driven gear 8 of oil pump 1 directly is connected on the right handle 4 of bent axle, therefore no matter which kind of rotating speed motor is in, the rotation of the right handle 4 of bent axle can drive driven gear 8 and rotate, driven gear 8 drives transition gear 7 rotations with its engagement, transition gear 7 drives the axle that connects on the transition gear and rotates, drive transition gear 6 thus and rotate, to finish lubricated work with the gearwheel 5 of its engagement.
Structure of the present utility model is applicable to the variable block motorcycle engine.
At the top of friction clutch 2 the manual clutch apparatus is set, can makes that free clutch engine has concurrently automatically, the performance of manual clutch.
Claims (2)
