Description

A kind of Electrical Bicycle brake gear

Technical field

The utility model relates to brake gear, relates in particular to the brake gear of Electrical Bicycle.

Background technology

Existing Electrical Bicycle brake gear mainly contains two kinds, first kind is the Purely mechanical brake gear, the power supply that drives Electric Bicycle Driver control electric-motor drive unit by rim brake realizes brake, during brake, produce a switch controlling signal by rim brake, the control unit that makes Electric Bicycle Driver carries out power operation to the motor of Electrical Bicycle in the process of mechanical brake; Brake mode to this Purely mechanical, the degree of wear of its braking effect and front brake parts, rear brake parts, the degree of tightness of front and back brake device conduction steel wire and the fine or not degree of front and back braking quality coupling all have very big relation, because the wearing and tearing of brake machinery parts or seasonal temperature change prolongation and the shortening that causes brake cable, all can influence braking effect; The Electrical Bicycle of this Purely mechanical brake gear is housed, and braking effect is bad to be the one of the main reasons that causes this Electrical Bicycle accident, and the kinetic energy that this brake mode causes Electrical Bicycle is not formed the energy feedback by meaningless having consumed.

Second kind of brake gear is the brake gear that has electronics assist brake (being E-ABS) function and mechanical type brake function simultaneously, the E-ABS signal triggering parts that trigger the electronics assist brake are installed in the rim brake of controlling mechanical brake, the signal output part of the mechanical brake signal triggering parts of E-ABS signal triggering parts and rim brake control is connected an input end of Electric Bicycle Driver jointly, in the time of the pinching rim brake, trigger E-ABS electronics assist brake function in the lump, promptly carried out mechanical brake and E-ABS brake simultaneously; For this brake gear, if the mechanical brake component function is relatively good, simultaneously, the E-ABS brake control technology of the Electric Bicycle Driver that is equipped with is reliable, can be greatly improved than the safety of first kind of Purely mechanical brake gear so, simultaneously, when carrying out E-ABS electronics assist brake, the closed power pipe of one of the counter electromotive force that produces brachium pontis of power bridge up and down by Electric Bicycle Driver and another be the flywheel diode that carries of conducting power tube itself not, electric current through power lead, is fed back to and is flushed in the electric power storage storage battery; Yet these two kinds of brake functions work simultaneously, and its distinctive shortcoming is also arranged, and this shortcoming just mechanical brake effect and E-ABS braking effect is covered mutually; If the mechanical brake parts adjust under the reasonable situation, even the E-ABS of controller brake controllable function disappears, the bicyclist does not know that still the E-ABS brake function is inoperative; Equally, even the associated components of pure mechanical brake is malfunctioning, have only the E-ABS function to work in the brake, it is ineffective that the bicyclist also is difficult to judge mechanical brake, and this has just buried hidden danger for accident.In fact, in the Electrical Bicycle traveling process, when in-plant unexpected accident occurred, emergency brake was the advantage of mechanical brake pattern; The advantage of independent E-ABS brake mode is that the resiliency of brake is good, feels comfortable, and simultaneously, the counter electromotive force natural back flow of electric bicycle motor has realized energy recovery during brake in battery, and advantage is apparent in view.But after the brake certain coasting distance is arranged.
