Abstract
The invention discloses a potentiometer adjusting mechanism of a scooter speed-adjusting device, which comprises a potentiometer, a potentiometer support and a speeder rod, wherein the speeder rod can drive a rotating rod of the potentiometer to rotate, and an offsetting torsion spring which can enable the speeder rod to be automatically return to the position is arranged on the support of the potentiometer. The mechanism is characterized by further arranging a shaft sleeve, wherein a limiting small shaft sleeve is arranged in the shaft sleeve, the rotating rod of the potentiometer is traversed through the shaft sleeve and the limiting small shaft in the middle of the shaft sleeve to connect with the speeder rod after traversing through the support of the potentiometer, thereby limiting the radial swinging of the rotating rod of the potentiometer within a normal range, and reducing the swinging scope of the rotating rod of the potentiometer under the action of the radial force from the speeder rod. A potentiometer briquette is further arranged on the mechanism, one ends of two foot slats of the briquette have certain gaps with the external top surface of the support of the potentiometer, which enables the swinging of the speeder rod to be limited in maximum, thereby the potentiometer works in a reasonable section, which prevents the potentiometer from being damaged, and prolongs the service life of the potentiometer. The mechanism has the advantages of simple structure, easy manufacturing and stable work.

The characteristics of the potentiometer governor motion of this speed control device of vehicle of riding instead of walk are: axle sleeve also is installed; Spacing little axle sleeve is installed in the middle of the said axle sleeve; The swingle of said potentiometer passes and passes axle sleeve behind the potentiometer support again and middle spacing little axle sleeve connects with speed control rod, and said reduction torsion spring is installed between axle sleeve and potentiometer support.
Said axle sleeve is the internal thread copper sheathing.
Between the internal diameter of said spacing little axle sleeve and potentiometer swingle external diameter is matched in clearance, is interference fit between the external diameter of said spacing little axle sleeve and the internal diameter of axle sleeve.
Fit clearance between the internal diameter of said spacing little axle sleeve and potentiometer swingle external diameter is 0.02mm～0.1mm.
Also be provided with the potentiometer briquetting, said potentiometer briquetting connects with speed control rod, and the swingle on the said potentiometer connects with speed control rod through the potentiometer briquetting.
Said potentiometer briquetting is provided with at least two feets, leaves the gap of setting between the outer end face of the bottom of said feet and potentiometer support.
The gap of the setting between the outer end face of the bottom of said feet and potentiometer support is 0.1mm～0.2mm.
Also be provided with the hold-down nut and the locked spacer that are used for fixing potentiometer and potentiometer support.
The beneficial effect of the present invention and prior art contrast is: reduction torsion spring is installed between axle sleeve and potentiometer support, avoids the thrust from the torsion spring that resets is delivered to the potentiometer swingle; Spacing little axle sleeve is installed in the middle of the axle sleeve, radially rocking of potentiometer swingle is limited in the normal radial extension, reduce the potentiometer swingle from the shaking amplitude under the radial load effect of speed control rod; The potentiometer briquetting is set, makes the feet and the little matched in clearance of potentiometer cradle top surface of potentiometer briquetting, make the rocking of speed control rod, thereby let potentiometer be operated in rational interval, avoid damaging potentiometer, prolong potentiometer useful life by maximum restriction; Simple in structure, make easily working stability.
