Abstract

The utility model relates to an energy-saving small flywheel on an auxiliary shaft of a chain transmission motorcycle, which is composed of a sprocket, a spline housing and an end cover. The utility model is characterized in that ratchets arranged at the inner circle of the sprocket; ratchets arranged at the outer circle of the spline housing, and splines arranged at the inner circle form a ratchet structure. The utility model alters the characteristic that the traditional flywheel and the auxiliary shaft synchronously run; the motorcycle is downgrade or runs on level roads after a gasoline throttle is turn down gradually or is completely turned off, makes full use of the inertia and saves energy.

Description

A kind of motorcycle is energy-conservation to fly for a short time

Technical field: the utility model relates to a kind of chain-driven motorcycle that is used for and pays upward flying for a short time of connection chain of axle.

Background technique: flying for a short time owing to tradition is a fixedly overall structure, its structures shape fly for a short time and pay the characteristic that axle rotates synchronously, when the motorcycle descending level road reduces or subtract throttle entirely after, sprocket wheel still drives the gear operation in the gearbox, thus aggravation component wear and increased oil consumption.

Summary of the invention: in order to address the above problem, the utility model provides a kind of and has energy-conservationly flown for a short time, can reach fuel-economizing and prolong the motorcycle purpose in working life.This energy-conservation flying for a short time is made up of sprocket wheel, spline housing and end cap three parts, the ratchet structure that the ratchet that puts by the ratchet on the garden wall in the sprocket wheel and Hua Jian is formed, make and pay axle and chain crop rotation relative movement, change tradition and flown for a short time and pair synchronous operated characteristic of axle, thereby made full use of the purpose that the coherence principle reaches fuel-economizing.Simultaneously novel ratchet structure can also reduce mechanical vibration, improves chaindriven stationarity, reduces the impact fatigue destruction of component wear and chain, thereby prolongs motorcycle working life, increases driving comfort.

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the outer garden of sprocket wheel (1) has sprocket (12) to be used for driving the motorcycle chain transmission, and Nei Yuanbi has ratchet (11); About respectively have one row steel bead groove (7) be used for adorning steel ball (4); The same sprocket wheel of steel ball dust slinger (16) (1) is an overall structure.

As Fig. 1, Fig. 2, Fig. 5, shown in Figure 6, spline housing (2) has 4 pawl slots (8), and 4 ratchets (5) are arranged in the groove; 4 spring grooves (10) are arranged, in spring (6) is arranged, there is spline housing steel bead groove (17) inboard, outer garden; Interior garden has with motorcycle pays the spline (15) that axle is connected; The outside thread (18) that connection end cap (3) are arranged.

Shown in Fig. 7,8, end cap (3) has 4 dismounting card eyes (13) to be used for dismounting end cap (3); There is end cap steel bead groove (14) inboard, outer garden, and there is the internal thread (9) of connection spline housing (2) in interior garden.

Embodiment: by accompanying drawing 1,2 combination and the working condition of above-mentioned parts as can be seen: the outer garden sprocket (12) on the sprocket wheel (1) is used for driving the motorcycle chain transmission; Steel ball (4) is contained in the interior left and right sides steel bead groove (7) of sprocket wheel (1), connects outside thread (18) by spline housing and is connected internal thread (9) connection with end cap, makes the same spline housing of sprocket wheel (1) (2), end cap (3) reduce the running friction.4 pawl slots (8) are arranged on the spline housing (2), 4 ratchets (5) are arranged in the groove, ratchet (5) is same ratchet (11) combination under the thrust of spring (6), forward drives spline housing (2) running, owing to ratchet (11) ratchet (5) is pressed in the pawl slot (8) in the time of oppositely, make spline housing (2) and the running of sprocket wheel (1) slide relative, thereby reach the purpose of unidirectional transmission.Assembly process is: in the spring groove (10) of spline housing (2) of earlier spring (6) being packed into, refill ratchet (5); In the left and right sides steel bead groove (7) in packing into steel ball (4) in the sprocket wheel (1), the spline housing (2) that will install ratchet (5) is then put in the sprocket wheel (1), loads onto end cap (3) and screws and get final product.Unload during use that motorcycle is former to fly for a short time, load onto this and fly for a short time to block and get final product with jump ring.

Claims

1, a kind of motorcycle is energy-conservation flies for a short time, is made up of sprocket wheel (1), spline housing (2) and end cap (3), it is characterized in that the interior garden of sprocket wheel (1) is provided with ratchet (11), establishes ratchet (5) on the outer garden of spline housing (2), and interior garden is spline (15).

2, motorcycle according to claim 1 is energy-conservation flies for a short time, the outer garden that it is characterized in that spline housing (2) is provided with (5) 4 on ratchet, is cross distribution, and the root of ratchet (5) is inserted in the pawl slot (8), be provided with spring (6) below the ratchet (5), spring (6) places in the spring groove (10).

3, motorcycle according to claim 1 is energy-conservation flies for a short time, it is characterized in that spline (15) is the hex key shape.
