Description
Technical field
The present invention relates to a kind of opposed pistons mechanical disc brakes suitable for national standard electric bicycle.
Background technique
Brake gear is relatively conventional in daily life, substantially covers entire vehicles system, primarily serves machine
The effect that vehicle, vehicle and other means of transports etc. stop or lower speed.As electric vehicle is using more and more, electric vehicle
Safety accident caused by riding is also more and more, in these accidents hypervelocity and caused by excessive velocities brake distance compared with
Accident caused by long occupies larger specific gravity；For the generation for reducing accident, country has formulated centainly the production and use of electric vehicle
Standard, such as: must have the function of it is foot-operated ride, max. speed is less than 25km/h, and motor rated power is less than 400w, and speed reaches
Prompt tone etc. is issued when to 15km/h, implementations of these standards is provided to safety when raising is ridden；However electric vehicle is ridden
Safety when row is largely still influenced by braking quality, and good braking effect is guarantee when riding.
Existing bicycle disc brake using it is more be drum brakes, drum brake is to utilize brake static in brake rim
Piece removes the brake rim to rub with vehicle wheel rotation, with generate frictional force turn a wheel speed reduction brake gear, stepping on
When brake pedal, the force of foot can make the piston in master cylinder push brake fluid forward and generate pressure in oil circuit, pressure
Power is transmitted to the wheel cylinder piston of each wheel via brake fluid, and the piston of wheel cylinder pushes brake block outside again, makes to stop
The inner face of vehicle piece and brake rim rubs, and generates enough friction and go to reduce the revolving speed of wheel, to reach the mesh of brake
's.But drum brakes has the disadvantages that the brake rim of 1, drum brakes will increase in heated rear diameter, and causes to step on brake
The stroke of pedal increases, and is easy to happen brake and reacts situation not as expected.2, brake system reacts slower, the pedal force of brake
Road is less easy to control, is unfavorable for doing high-frequency brake.3, construction complex parts are more, and braking gap must adjust, so that
Maintenance is not easy, while drum brake structure brake weight is small, and maintenance is inconvenient；This is easy for causing safety accident, therefore this brake modes
It has not been suitable for existing national standard electric bicycle standard, therefore has been badly in need of improving existing brake modes.
Summary of the invention
It is high that the technical problem to be solved in the present invention is to provide a kind of braking efficiencies, and good braking effect can be carried out two-sided brake,
Brake disc will not deform when brake, when brake brake block will not locking, it is highly-safe, while can be at any time to the elastic of brake block
It is adjusted, guarantees that the normal use of brake block, security performance are ensured significantly, with practicability and use the suitable of popularity
