CN2740832Y - Idle oil-saving gear device of motorcycle - Google Patents

Abstract

A motorcycle idle speed fuel-saving geared device relates to a motorcycle speed idling device. The existing motorcycle doesn't have a, so a gear and the output axis of a gear box are connected together during the rotation. The motorcycle idle speed can not disengage from brake of the gearbox when the motorcycle idling the speed. All gears in the gearbox consume power because of the rotation. So an idle oil-saving gear device of the motorcycle with simple structure which can effectively disengage the internal gears of the gearbox from braking is provided to solve these problems. The utility model adopts the technical proposal that the top circle of the collar plate 1 with inner teeth is provided with gear ring 3; the collar plate 1 with inner teeth and two external end-face of the geared ring 3 are separately provided with a left cover board 2 and a right cover board 4; the screw 5 threads the hole of the collar plate 1 with inner teeth, and two end of screw 5 mesh with thread of the left cover board 2 and the right cover board; the external ring of the collar plate with inner teeth is provided with an off-center circular groove which is provided with spring 6 and pin roller 7.

Description

Motorcycle idling oil-saving gear device

One, technical field

The utility model relates to motorcycle idling device, especially a kind of motorcycle idling oil-saving gear device.

Two, background technique

The inner nothing of existing motorcycle ordinary gear surmounts the disk that has interior tooth, on-stream gear and transmission case output shaft are connected as one, and can not move mutually, therefore, motorcycle can not break away from the braking of transmission case under idling mode, inner all gears of transmission case all will rotate and consumption of power.

Three, summary of the invention

The purpose of this utility model provides a kind of simple in structure, can effectively break away from the idling oil-saving gear device of the braking of transmission case internal gear.

The technological scheme that the purpose of this utility model adopted is, include the disk of tooth in having, the disk cylindrical of tooth was equipped with gear ring in it had, the disk and gear ring two exterior edge faces of tooth have left cover and right cover plate respectively in having, in screw passes and has the hole, two ends of the disk of tooth respectively with left cover and right cover plate thread engagement, the disk outer shroud of tooth has the eccentric arc groove in having, and device has spring and roller in the eccentric arc groove.

When using the utility model, the disk of tooth connects with the transmission case output shaft in having, the inner driving gear engagement of gear ring and transmission case.When motorcycle is run at high speed, the high engine speeds operation, the roller that makes the eccentric arc groove of the disk of tooth in having is under centrifugal action, by moving of eccentric arc groove width to narrow direction, make the disk and the gear ring formation that have interior tooth be closely connected, therefore from the power of the inner driving gear of transmission case, the disk through gear ring tooth in have passes to the transmission case output shaft at last; Motorcycle travels in idling, motor is operation at a slow speed, make the roller of the eccentric arc groove of the disk of tooth in having little at centrifugal action, by narrow the moving of eccentric arc groove to wide direction, making the disk that has interior tooth form running fit with gear ring is connected, the transmission that breaks away from the transmission case internal gear relies on the idle running of the disk of tooth in having and bore and consumption of engine power not plays the fuel-economizing effect.Be unkitted motorcycle of the present utility model and compare with similar, but fuel-economizing 15%-25%.After means of motorcycle gearbox uses the utility model, obvious by facts have proved oil-saving effect, and driving torque is big, and dry sound is little, and stable performance is welcome by consumers in general deeply.

Four, description of drawings

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model sectional structure schematic representation;

Fig. 2 is that Figure 1A-A is to the TV structure schematic representation.

Among the figure: the right cover plate 5-of the disk 2-left cover 3-gear ring 4-of tooth screw 6-spring 7-roller in 1-has

Five, embodiment

As shown in Figure 1 and Figure 2, disk 1 cylindrical of tooth is equipped with gear ring 3 in having, the disk 1 of tooth has left cover 2 and right cover plate 4 respectively with 3 liang of exterior edge faces of gear ring in having, in screw 5 passes and has the hole, two ends of the disk 1 of tooth respectively with left cover 2 and right cover plate 4 thread engagement, disk 1 outer shroud of tooth has the eccentric arc groove in having, and device has spring 6 and roller 7 in the eccentric arc groove.

Claims (1)

1, a kind of motorcycle idling oil-saving gear device, include the disk (1) of tooth in having, disk (1) cylindrical of tooth is equipped with gear ring (3) in it is characterized in that having, the disk (1) of tooth has left cover (2) and right cover plate (4) respectively with gear ring (3) two exterior edge faces in having, in screw (5) passes and has the hole, two ends of the disk (1) of tooth respectively with left cover (2) and right cover plate thread engagement, disk (1) outer shroud of tooth has the eccentric arc groove in having, and device has spring (6) and roller (7) in the eccentric arc groove.
