Abstract
The utility model relates to a motor-driven main shaft anti-reversing device for light motorcycles and powered vehicles. According to the technical scheme provided by the utility model, the motor-driven main shaft anti-reversing device comprises a main shaft and a main shaft gear mounted on the main shaft. The motor-driven main shaft anti-reversing device is characterized in that a one-way needle roller bearing is mounted in an inner hole of the main shaft gear; the outer ring of the one-way needle roller bearing is in interference fit with the inner wall of the main shaft gear; the main shaft is arranged in an inner hole of the one-way needle roller bearing; and the main shaft and the one-way needle roller bearing can rotate relative to each other in only one direction. The motor-driven main shaft anti-reversing device can achieve power transmission and speed reduction of a motor to a counter shaft and a rear wheel of the light motorcycles and the powered vehicle, and simultaneously, can achieve gliding of the rear wheel.
Description
Technical field
The utility model relates to a kind of engine power transmission device, especially a kind of trail bike and boosted vehicle engine-drive main shaft non-return device.
Background technology
Because human society is the requirement of development constantly, High Performance and high efficiency have become the developing goal of driving engine.All the time, former trail bike of the same type and boosted vehicle all do not have non-return device with the engine-drive main shaft, and when the engine power cut-out, when no longer including takeoff output, trailing wheel does not have wheel function, can instead drag driving engine, increases consumption of power, and oil consumption improves.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and guarantees that the power of driving engine fully transmits, reduces the engine-drive main shaft non-return device of oil consumption.
The technical scheme that provides according to the utility model, described trail bike and boosted vehicle engine-drive main shaft non-return device, comprise main shaft and the reaction gear that is installed on the main shaft, it is characterized in that: unidirectional needle bearing is packed in the endoporus of reaction gear, interference fit between the outer ring of unidirectional needle bearing and the inwall of reaction gear, main shaft is packed in the endoporus of unidirectional needle bearing, can only relatively rotate in one direction between main shaft and the unidirectional needle bearing.
On described main shaft gear is set, described main shaft and described gear fuse, and described gear is less than described reaction gear.On the main shaft between described gear and described reaction gear, be with space washer.
The beneficial effects of the utility model are: realized trail bike and boosted vehicle with the engine power transmission, be decelerated to countershaft and trailing wheel, simultaneously can realize the trailing wheel wheel function again.Main shaft non-return device of the present utility model has increased the trailing wheel wheel function reliably, can improve the power conversion rate of driving engine, reduces oil consumption.Therefore be applied to trail bike and booster vehicle engine, the energy consumption that can satisfy trail bike and booster vehicle engine is low, high efficiency requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: engine-drive main shaft non-return device comprises main shaft 1, reaction gear 2, unidirectional needle bearing 3 etc.
The utility model comprises main shaft 1 and the reaction gear 2 that is installed on the main shaft 1, it is characterized in that: unidirectional needle bearing 3 is packed in the endoporus of reaction gear 2, interference fit between the inwall of the outer ring of unidirectional needle bearing 3 and reaction gear 2, main shaft 1 is packed in the endoporus of unidirectional needle bearing 3, can only relatively rotate in one direction between main shaft 1 and the unidirectional needle bearing 3.On described main shaft 1 gear 5 is set, described main shaft 1 fuses with described gear 5, and described gear 5 is less than described reaction gear 2.On the main shaft 1 of 2 of described gear 5 and described reaction gears, be with space washer 4.
Working process of the present utility model: at first during the driving engine normal operation, takeoff output is to main shaft 1, and this moment, main shaft 1 drove reaction gears 2 by unidirectional needle bearing 3, drove to countershaft, drove trailing wheel and rotated forward, caused vehicle to overtake; Reduce and work as engine throttle, when no longer including takeoff output, because inertia, vehicle still moves ahead, and trailing wheel continues to rotate forward.At this moment, reaction gear 2 continues to rotate forward, because the effect of unidirectional needle bearing 3 makes reaction gear 2 can't drive main shaft 1 rotation, has realized the trailing wheel wheel function, can improve the power conversion rate of driving engine, reduces oil consumption.
