Abstract
A braking system (3), in particular emergency braking system, in a drive unit, which drive unit includes at least one motor (8) and at least one unit (6) driven by the motor (8). The braking system has: a plurality of controllable brakes (16a-16b), which are arranged and designed to act on the drive unit; and a controller (12), which is designed to preselect and accordingly pilot-control a number of brakes (16a-16b) from amongst said plurality of brakes (16a-16b) depending on a state or load situation of the drive unit, so that, when the braking system (3) is activated, the drive unit can be acted on only by way of said preselected number of brakes (16a-16b).
Claims19
A braking system (3) in a drive unit, which drive unit comprises at least one motor (8;
- 8a, 8b) and at least one driven unit (6;
- 6a, 6b) that is driven by the motor (8;
- 8a, 8b), the braking system comprising:
- a plurality of controllable brakes (16a-16d), which are arranged and designed to act on the drive unit, wherein at least one of the brakes (16a-16d) is operatively connected to a pilot-controllable valve (17);
- a controller (12), which is designed to actuate the brakes (16a-16d) in accordance with pilot control of the valve (17) depending on a state or load situation of the drive unit;
- the valve (17) has a latching function;
- and
- the latching function of the valve (17) is adapted to be pilot-controlled by the controller (12), so that a number of the brakes (16a-16d) from amongst said plurality of brakes (16a-16d) is preselected, so that, when the braking system (3) is activated, the drive unit is adapted to be acted on only by way of said preselected number of brakes (16a-16d).
The braking system (3) as claimed in claim 18, wherein the load measuring pin (7) is operatively connected to the cable (5).

(canceled)
A method for braking with variable braking force in a drive unit, said drive unit comprises at least one motor (8;
- 8a, 8b) and at least one unit (6;
- 6a, 6b) driven by the motor (8;
- 8a, 8b), the method comprising:
- a) providing a braking system (3) having a plurality of controllable brakes (16a-16d), which are arranged and designed to act on the drive unit;
- b) determining a state or load situation of the drive unit;
- and
- c) making a preselection of a variable number of the brakes (16a-16d), the number being dependent on the determined state or load situation, from said plurality of brakes (16a-16b) by a controller (12) depending on the determined state or load situation, which preselection, based on a corresponding pilot control of the brakes (16a-16d), has the effect that, when the braking system (3) is activated, the drive unit is adapted to be acted on only by way of said preselected number of the brakes (16a-16d).
