Brake system

Technical field

The utility model relates to a kind of brake systems, belong to brake technique field.

Background technique

Currently, there are two types of mainstream brake systems, drum brakes braking system and disk type brake braking system.But Both brake systems have disadvantage or defect now:

One, the shortcomings that drum brakes braking system:

(1) the phenomenon that thermal diffusivity is poor, will cause brake decline when continuously trampling brake and makes brake failure；

(2) changes of size make the to touch on the brake stroke of pedal increases after being heated, not easy to control；

(3) it reacts slower, is not suitable for doing high-frequency brake, hardly consistent with the demand of ABS system；

(4) closure causes drainage poor, the powder of brake component, and water or silt will cause the undesirable situation of brake；

(5) built in component closing, construction is complicated, and maintenance is inconvenient；

(6) discontinuity when brake drum braking brake, service life is short, is easily broken, and causes danger.

Two, disk type brake braking system disadvantage:

(1) braking-force ratio drum brake power is low, influences braking distance, threatens safety；

(2) rubbing surface between brake(-holder) block and brake disc is smaller, and the strength of braking is also smaller, therefore needs biggish pedal force Amount or oil pressure lead to that the brake disc being relatively large in diameter must be used, or improve the oil pressure of braking system, to improve the power of brake Amount, thus component weight increases, and influences entirety；

(3) lever brake is not easy to install, and rear-wheel need to add the parking brake of one group of drum brakes using the vehicle of disc type brake Mechanism of car.Cost and weight increase therewith；

(4) braking pad wear is larger, causes replacement frequency may be higher, and use cost is expensive.
