Abstract

电动自行车超越离合器，其特征在于有一个安装在轴上的圆柱形棘爪座，圆柱形棘爪座的外周壁上制有半圆形的凹槽和直线斜口，在半圆形凹槽和直线斜口中安装相配合的棘爪，在棘爪座外有圆柱形棘齿圈，圆柱形棘齿圈内壁中制有棘齿，棘齿与棘爪相接触。本技术方案利用棘爪、棘齿的作用达到离合器的目的，当电机工作时，棘爪卡入外棘齿圈内与棘齿相接触，外棘齿圈与车轮相连，电机和棘爪座等带动外棘齿圈及车轮旋转作功；而当电机停止工作时，棘爪与外棘齿圈自动分离，外棘齿圈与车轮继续转动，使车继续行驶一段路程，节省电能。

Figure 200720111692

The electric bicycle overrunning clutch is characterized in that there is a cylindrical ratchet seat installed on the shaft, and a semicircular groove and a linear bevel are formed on the outer peripheral wall of the cylindrical ratchet seat. Matching ratchets are installed in the linear slanted mouth, and a cylindrical ratchet ring is arranged outside the ratchet seat. A ratchet is formed in the inner wall of the cylindrical ratchet ring, and the ratchet contacts with the ratchet. This technical solution uses the function of the pawl and ratchet to achieve the purpose of the clutch. When the motor is working, the pawl is inserted into the outer ratchet ring to contact the ratchet, the outer ratchet ring is connected with the wheel, the motor and the pawl seat, etc. Drive the outer ratchet ring and the wheel to rotate to do work; and when the motor stops working, the pawl and the outer ratchet ring are automatically separated, and the outer ratchet ring and the wheel continue to rotate, so that the car can continue to travel for a certain distance and save electric energy.

Description

The electric bicycle free wheel device
Technical field
The utility model relates to the electric bicycle free wheel device, belongs to the power accessory of electric bicycle.
Background technique
Electric bicycle relies on machine operation to drive wheel, but motor one quits work, and motor body just becomes load on the contrary, wheel is stopped operating very soon, and power loss is big, particularly when descending, originally the suitable one section distance that can continue to travel stops soon, increases power consumption.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, and when providing a kind of motor to quit work, motor and wheel disengage, and makes the wheel stretch journey that continues to travel under the effect of inertial force, saves the electric bicycle free wheel device of electric energy.
The technological scheme of the utility model electric bicycle free wheel device is: it is characterized in that the cylindrical pawl base that has one to be installed on the axle, be shaped on semicircular groove and straight line angle on the periphery wall of cylindrical pawl base, the ratchet that matches is installed in semi-circular recesses and straight line angle, cylindrical ratchet ring is arranged outside pawl base, be shaped on ratchet in the cylindrical ratchet ring inwall, ratchet contacts with ratchet.
Electric bicycle free wheel device of the present utility model, utilize the effect of ratchet, ratchet to reach the purpose of clutch, when machine operation, ratchet snaps in the outer ratchet ring and contacts with ratchet, outer ratchet ring links to each other with wheel, and motor and pawl base etc. drive outer ratchet ring and wheel rotation work done; And when motor quit work, ratchet separated automatically with outer ratchet ring, and outer ratchet ring and wheel are rotated further, and made the car stretch journey that continues to travel, and saved electric energy.
Description of drawings
Fig. 1 is the utility model electric bicycle free wheel device structural representation.
Embodiment
The utility model relates to the electric bicycle free wheel device, as shown in Figure 1, its major technology is characterised in that a cylindrical pawl base 2 that is installed on the axle, be shaped on semicircular groove 21 and straight line angle 22 on the periphery wall of cylindrical pawl base, the ratchet 3 that matches is installed in semi-circular recesses 21 and straight line angle 22, cylindrical ratchet ring 1 is arranged outside pawl base 2, be shaped on ratchet 11 in cylindrical ratchet ring 1 inwall, ratchet 11 contacts with ratchet 3.The utility model utilizes the effect of ratchet, ratchet to reach the purpose of clutch, and when machine operation, ratchet snaps in the outer ratchet ring and contacts with ratchet, and outer ratchet ring links to each other with wheel, and motor and pawl base etc. drive outer ratchet ring and wheel rotation work done; And when motor quit work, ratchet separated automatically with outer ratchet ring, and outer ratchet ring and wheel are rotated further, and made the car stretch journey that continues to travel, and saved electric energy.
