Brake device and electrically operatable axle drivetrain of a motor vehicle

ActiveUS12637035B2Braking element arrangementsFluid actuated brakesDrivetrainControl theory
A brake device for an electrically operatable axle drivetrain of a motor vehicle includes a hydraulic disengaging system comprising a central disengaging element which actuates a friction device such that the friction device operates in a braking or non-braking state. The central disengaging element has a central disengaging element housing comprising a central disengaging element piston chamber in which a central disengaging element piston is received in an axially movable manner by means of a hydraulic liquid. The central disengaging element has at least one central disengaging element piston seal which seals off the central disengaging element piston from the central disengaging element piston chamber, and the central disengaging element and the friction device are received in a brake housing, the brake housing including a first pot-shaped housing part and a second lid-shaped housing part which at least partly covers the first pot-shaped housing part.

Compact multi-function clutch

PendingUS20260168550A1Fluid actuated brakesFluid actuated clutchesControl theoryBrake fluid
A clutch includes a clutch fluid chamber with a movable clutch piston configured to selectively engage a clutch pack to connect an input drive portion and an output portion. A brake reaction plate is configured for selective frictional braking of the output portion. A brake fluid chamber contains a brake piston configured to selectively move the brake reaction plate from a disabled position to an enabled position. In a first state, the clutch pack is disengaged and the brake reaction plate is in the disabled position. In a second state, the clutch pack is engaged and the brake reaction plate is in the enabled position, without frictional braking of the output portion of the clutch being applied. In a third state, the clutch pack is disengaged and the brake reaction plate is in the enabled position such that frictional braking of the output portion is applied.

Powertrain for an electric vehicle

ActiveDE102024137302A1Fluid actuated brakesBraking element arrangements
The invention relates to a drive train (1) for an electric vehicle comprising an electric motor (2) with a rotor shaft (3) arranged on a drive axle (d(an)) and an output axle (d(ab)) arranged parallel to it, with a differential (5) and two cardan shafts connected to the differential (5), each with drive wheels and externally actuated service brakes (10, 11), as well as a transmission (4) arranged between the drive axle (d(an)) and the output axle (d(ab)). To better protect the service brakes (10, 11) from external influences, the service brakes (10, 11) are arranged directly on the differential (5).

A wet disc brake

A wet disc brake (16) for an off-highway vehicle is provided. The wet disc brake (16) includes a brake caliper (20); a disc pack (22) located within the brake caliper (20) and rotatably fixed to a vehicle shaft, the shaft having a longitudinal axis extending in an inboard-outboard direction; a service piston (24) actuatable within the brake caliper (20) during a brake operation to compress the disc pack (22) to inhibit rotation of the shaft and slow the vehicle; and a parking piston (30) coaxial with the service piston (24) and actuatable within the brake caliper (20) during a parking operation to apply a force to the service piston (24) to actuate the service piston (24). At least a portion of the parking piston (30) axially overlaps the service piston (24) in the inboard-outboard direction.
