B60T8/40 - CPC Classification

Classification description:

Arrangements for adjusting wheel-braking force to meet varying vehicular or ground-surface conditions, e.g. limiting or varying distribution of braking force responsive to a speed condition, e.g. acceleration or deceleration having a fluid pressure regulator responsive to a speed condition comprising an additional fluid circuit including fluid pressurising means for modifying the pressure of the braking fluid, e.g. including wheel driven pumps for detecting a speed condition, or pumps which are controlled by means independent of the braking system

Sub-classes:

B60T8/4004 » {Repositioning the piston(s) of the brake control means by means of a fluid pressurising means in order to reduce the brake pressure} 7
B60T8/4013 » {Fluid pressurising means for more than one fluid circuit, e.g. separate pump units used for hydraulic booster and anti-lock braking} 9
B60T8/4018 » {Pump units characterised by their drive mechanisms } 56
B60T8/4031 » {Pump units characterised by their construction or mounting } 207
B60T8/4036 » {Pump units characterised by their failure-responsive means } 18
B60T8/404 » {Control of the pump unit} 38
B60T8/4068 » {the additional fluid circuit comprising means for attenuating pressure pulsations} 68
B60T8/4072 » {Systems in which a driver input signal is used as a control signal for the additional fluid circuit which is normally used for braking} 124
B60T8/4095 » {including wheel driven pumps for detecting a speed condition} 3
