Abstract

An scooter energy-saving device is that an idler wheel gear shaft (3) is installed between an input shaft (1) and an output shaft (2). A gear (4) on the shaft is meshed on a gear (5) on the output shaft (2). The shaft is also provided with an idler wheel (6). The idler wheel (6) excircle is opened with a groove (7) in which the inside is provided with a pawl. One end of the pawl (8) is disposed inside an inner slot (10) of the groove (7). A spring (11) is arranged between the pawl (8) and the bottom of the groove (7). A ratchet wheel (12) is jacketed on the idler wheel (6) excircle. Through an end cover (13) and a screw (15), the idler wheel (6) and the ratchet wheel (12) are opposed and fixed on the axial direction. The inner hole of the ratchet wheel (12) is provided with ratchets (16), and the excircle is a gear (17) meshed with a gear (18) of the input shaft (1). The utility model allows that the clutch action of scooter can be automatic implemented in downhill slide or high-speed slide, so that the purpose of energy conservation, wear decreasing and life extending can be reached.

Description

The scooter energy saver

Technical field

The utility model relates to a kind of energy saver, particularly a kind of energy saver that is used for scooter.

Background technology

Existing scooter driving device does not have energy saver, and when the scooter downhill running or run at high speed when sliding, driving engine still needs work, can not realize energy-conservation.

Summary of the invention

The purpose of this utility model is to provide a kind of energy saver simple in structure, at the scooter downhill running or run at high speed and play clutch action when sliding automatically, when making tail-off, scooter can continue to slide, thereby reaches the purpose of energy saving and pollution alleviation, reduction wearing and tearing and life-saving.

The utility model is achieved in that a kind of scooter energy saver, one idler gear wheel shaft is housed between input shaft and output shaft, gear on the idler gear wheel shaft and the gear mesh on the output shaft, on the idler gear wheel shaft idle pulley is housed, the idle pulley cylindrical has groove, ratchet is housed in the groove, ratchet one end is arranged in the inside groove of groove, between ratchet and the bottom portion of groove spring is housed, the idle pulley cylindrical is with ratchet, makes idle pulley and ratchet in axial relative fixed by end cap, screw, and the ratchet endoporus is processed with ratchet, cylindrical is a gear, the gear mesh of gear and input shaft.

The beneficial effects of the utility model are: when the scooter downhill running or run at high speed when sliding, car owner's throttle that breaks, engine output shaft is outputting power no longer, output shaft speed descends, since effect of inertia, the just relative and idle pulley slip of ratchet, make scooter continue to slide, thereby saved fuel oil, and reduced exhaust emission and mechanical wear, prolonged driving engine service life.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is an A-A cutaway view among Fig. 1.

The specific embodiment

By above-mentioned accompanying drawing as can be known, the utility model is that an idler gear wheel shaft 3 is housed between input shaft 1 and output shaft 2, gear 4 on the idler

gear wheel shaft

3 and 5 engagements of the gear on the output shaft 2, idle pulley 6 is housed on the idler gear wheel shaft 3, idle pulley 6 cylindricals have groove 7, ratchet 8 is housed in the groove 7, ratchet 8 one ends are arranged in the inside groove 10 of groove 7, between ratchet 8 and groove 7 bottoms spring 11 is housed, idle pulley 6 cylindricals are with ratchet 12, by end cap 13, screw 15 makes idle pulley 6 and ratchet 12 in axial relative fixed, and ratchet 12 endoporus are processed with ratchet 16, cylindrical is a gear 17, and gear 17 meshes with the gear 18 of input shaft 1.

In this example, input shaft 1 is the scooter engine output shaft, and output shaft 2 is the rear axle driven gear shaft.

Described spring 11 can be reed.

The groove 7 that described idle pulley 6 cylindricals are opened can be set to 3.
