CN2357994Y - Energy-saving driving device for motorcycle - Google Patents

Abstract

The utility model relates to an energy-saving driving device for a motorcycle, which is mainly characterized in that a one-way overrunning device with a rolling rod, a roller ball and a retaining ring is arranged on an output shaft of the motorcycle. The one-way overrunning device is fixedly connected with the output shaft; a chain wheel or an inner hole of a gear is in rigid connection with the rolling rod of the one-way overrunning device. The utility model is suitable for being arranged on a riding type cycle with two-stroke or four-stroke or a scooter; the effect on saving energy is obvious; the discharge amount of exhaust gas is reduced; the service life of a motor is extended.

Description

The energy-conservation driving device of motor bike

The utility model relates to a kind of vehicle transmission gear, particularly relates to the energy-conservation driving device of a kind of motor bike.

Existing motor bike driving device, general adopt driving system and be one, when the motor bike Reduced Speed Now, because drive wheel is subjected to the effect of anti-drive system by the drive wheel of driving system, not only want fuel consumption, also quickened the wearing and tearing of each parts of motor cycle engine and driving system.

The purpose of this utility model is the deficiency that overcomes above-mentioned driving system, provides a kind of motor bike of saving the energy, reducing wear energy-conservation driving device.

The utility model is except including motor bike output shaft, sprocket wheel or gear, and its principal feature is the mono-directional overrun device that has additional band roller, ball, back-up ring on the motor bike output shaft; Said mono-directional overrun device and output shaft fixed connection connect, and the roller of the sprocket wheel of motor bike or the endoporus of gear and mono-directional overrun device joins, and are built-in with ball at the roller outside, back-up ring.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model A-A cut-away view.

Among the figure: 1, mono-directional overrun device, 2, mono-directional overrun device roller, 3, ball, 4, output shaft, 5, sprocket wheel or gear, 6, back-up ring, 7, fix screw, 8, fix shaft, 9, locating dowel pin, 10, spring, 11, boss.

As shown in Figure 1, the utility model is to set up a mono-directional overrun device 1 that has roller 2, ball 3, a back-up ring 6 on the output shaft 4 of motor bike, and mono-directional overrun device 1 is solidly connected with output shaft 4 usefulness screws 7.The endoporus of sprocket wheel or gear 5 (riding type car is that sprocket wheel, scooter are gear) contacts with mono-directional overrun device roller 2 cylindricals, and in the side of roller 2, back-up ring 6 is built-in with ball 3, is used for alleviating the wearing and tearing between back-up ring 6 and sprocket wheel or the gear 5.When motor bike moved ahead, because the endoporus of sprocket wheel or gear 5 contacts with the cylindrical rigidity of mono-directional overrun device roller 2, output shaft 4 turned round in the same way with mono-directional overrun device 1.When motor bike slows down, the rotating speed of sprocket wheel or gear 5 reduces or stops, but output shaft 4 still is rotated further under its action of inertia with the mono-directional overrun device, and at this moment driving system and driving engine are not subjected to the anti-driving action of output shaft 4, but thereby the driving engine tickover is realized fuel-economizing 25～43%.

Also can be according to actual conditions, anti-when dragging function as needing by bike, on the appropriate location of mono-directional overrun device 1, establish the boss 11 of a band spring 10, locating dowel pin 9, fix shaft 8, need with anti-when dragging function, advance fix shaft 8, mono-directional overrun device 1 is connected with sprocket wheel or gear 5 with output shaft 4, can recover the anti-function of dragging, not the time spent, extract fix shaft 8 and get final product.

Energy-conservation driving device of the present utility model can be installed on striding type or the scooter, and double stroke, four stroke all are suitable for.Simple in structure, energy-saving effect is obvious, and no variable block, gearshift difficulty batter down gear and fracture chain phenomenon.Discharge amount of exhaust gas reduces, and has prolonged the service life of driving engine.

Claims (2)

1, the energy-conservation driving device of a kind of motor bike, include motor bike output shaft 4, sprocket wheel or gear 5, it is characterized in that: the mono-directional overrun device 1 that has additional band roller 2, ball 3, back-up ring 6 on the motor bike output shaft 4, described mono-directional overrun device 1 is solidly connected with output shaft 4, the roller 2 of the endoporus of sprocket wheel or gear 5 and mono-directional overrun device 1 joins, and roller 2 outsides, back-up ring 6 are built-in with ball 3.

2,, it is characterized in that also being provided with on the mono-directional overrun device 1 the cam platform 11 of a band spring 10, locating dowel pin 9, fix shaft 8 according to the described energy-conservation driving device of claim 1.
