Description
Technical field
The utility model relates to a kind of brake device for car, especially relates to the brake device for car that a kind of clamp drag moment of torsion and liquid measure displacement optimization.
Background technique
At present, the clamp piston packing of passenger car drag angle assembly determines the liquid measure displacement (brake disc friction plate gap) of clamp and drags moment of torsion, the liquid measure displacement of clamp (brake disc friction plate gap) is a pair of conflicting parameter with dragging moment of torsion: clamp liquid measure displacement large (brake disc friction plate gap) drags moment of torsion little; Otherwise liquid measure displacement (brake disc friction plate gap) is little, drags moment of torsion large.From the braking system aspect of performance, the liquid measure displacement of trying one's best little (brake disc friction plate gap) can obtain less slack of pedal.Try one's best and little drag moment of torsion and can reduce oil consumption, the heel and toe wear of reduce friction sheet and brake disc.
Existing brake caliper technical requirements and design proposal are based on clamp liquid measure displacement (brake disc friction plate gap) and drag in the moment of torsion parameter and obtain a relative equilibrium parameter and decide clamp seal ring size and fit dimension.But be difficult in the situation that guarantee the moment of torsion that drags of less clamp liquid measure displacement (brake disc friction plate gap) elimination clamp.
