CN201148188Y - Forcipated brake of electric bicycle - Google Patents

Abstract

The utility model discloses a forcipate brake for an electric bicycle. In the technical scheme, the forcipate brake is applied, a braking disc is arranged on the hub of a wheel and rotates along with wheels, the shell of the forcipate brake is floatingly arranged on a frame, and two braking blocks are arranged in a forcipate form on both sides of the braking disc. The braking blocks are pushed by a threaded shaft, and the shell of the forcipate brake serves as a nut. Utilizing the screw-nut transmission theory, a brake cable pulls a rocker on the threaded shaft, and the rocker swings for an angle to drive the threaded shaft to rotate; the rotating threaded shaft generates axial displacement to push the braking blocks; as the braking blocks press toward the braking disc, the floatingly installed shell of the forcipate brake moves in a reverse direction; as a result, the two braking blocks vice the braking disc, and friction generates braking torque, thus braking the electric bicycle. The forcipate brake is characterized by simple structure, low production cost, convenient installation, use and maintenance and good economic benefit; in particular, the forcipate brake can greatly reduce traffic accidents caused by braking failure, so social benefit is obvious; the forcipate brake does not generate noise, thus meeting the requirement on urban environmental protection.

Description

The pincerlike drg of Electrical Bicycle

Affiliated technical field

The utility model can be applied on Electrical Bicycle, battery-operated motor cycle, morpet and the extraordinary bicycle, has safety arrestment and does not have noise.

Background technology

At present, the used drg of Electrical Bicycle and morpet is generally cycle brake.So when riding speed was very fast, because of deceleration and stopping performance does not with great difficulty cause safety misadventure, the noise that braking produces when urban highway travels was very ear-piercing.Cycle brake generally is that the front-wheel rubber block compresses rim, trailing wheel is held brake wheel tightly with brake band, when road speed less than 20 kilometers/hour, braking effect is safe, when road speed greater than 20 kilometers/hour, even if brake simultaneously front and back, can not guarantee brake safe, the traffic accident of Yin Faing is in rising trend therefrom.

Summary of the invention

The Electrical Bicycle that urban highway travels is more and more, and moving velocity is more and more faster, because the accident of the ineffective initiation of braking and dispute are more and more.Simultaneously, Electrical Bicycle is as the light environment-friendly type vehicle, more and more be subjected to common people's welcome, like this, reliable and the New Brake easy to use simple in structure of brake safe, can fundamentally address this problem, his employing will bring good economic benefit and social benefit, is rising product.

The technical scheme that its technical matters that solves the utility model adopts is: adopt pincerlike drg, brake disc is installed on the wheel hub of wheel, with wheel.Pincerlike brake shell floats and is installed on the vehicle frame, two slipper pincers are distributed in the brake disc both sides, slipper is promoted by lead screw shaft, pincerlike brake shell is equivalent to nut, utilize the transmission principle of feed screw nut, rocking arm on the brake cable pulling lead screw shaft, angle of rocking arm swing drives lead screw shaft and rotates, and the lead screw shaft rotation just produces longitudinal travel and promotes slipper.When slipper was pressed to brake disc, the pincerlike brake shell of installing that floats moved to reversing sense, and like this, two slipper just vise brake disc, form lock torque by friction, realize the braking to Electrical Bicycle.

The beneficial effects of the utility model are, can safe and effective braking Electrical Bicycle and morpets, and simple in structure, low cost of manufacture, installation, use, easy to maintenance, good in economic efficiency; Particularly can reduce greatly owing to the ineffective traffic accident that causes of braking, social benefit is obvious; Do not have brake noise, meet the urban environmental protection requirement.

Description of drawings

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

Fig. 1 is pincerlike drg fundamental diagram.

Fig. 2 is pincerlike brake structural scheme drawing.

1-brake disc among the figure, the 2-brake shell, the 3-slipper, the 4-rocking arm, the 5-retracing spring, the 6-back-up ring, the 7-screw, the 8-lead screw shaft, 9-drg end cap, the 10-bolt, the 11-oil sealing, 12-is covered with dust.

The specific embodiment

In Fig. 1, brake disc (1) is installed on the wheel hub, pincerlike brake shell (2) floats and is installed on the vehicle frame, hold brake the time, brake pulling wire pulling rocking arm (4), rocking arm drives lead screw shaft (8) and rotates an angle, lead screw shaft (8) and pincerlike brake shell (2) are screw thread pair, lead screw shaft is rotated and is just produced longitudinal travel, promotes the two-way brake disc (1) that compresses of slipper (3), utilizes the friction force abrupt deceleration vehicle.Work as end of braking, the release the brake brake lever, rocking arm (4) return under the effect of retracing spring (5), rocking arm goes back to the home position together with lead screw shaft, and slipper (3) take-off the brake dish (1) is removed vehicle braked.

Claims (1)

1. the pincerlike drg of an Electrical Bicycle, it includes: brake disc, slipper, brake shell, it is characterized in that: pincerlike brake shell floats and is installed on the vehicle frame, two slipper pincers are distributed in the brake disc both sides, lead screw shaft connects a side slipper, pincerlike brake shell connects the opposite side slipper, and lead screw shaft and pincerlike brake shell are screw thread pair.
