A vehicle includes a continuous braking device. The continuous braking device includes a non-firing piston engine which can be drivingly coupled to a drive train shaft of the vehicle and is configured, during operation, for conveying air from an air inlet of the piston engine to an air outlet of the piston engine and for thereby compressing the air and for causing deceleration of the vehicle by performing compression work.

The present invention relates to a traveling working machine, in particular a hydraulic excavator, with a traveling gear and with a hydraulic service brake system for the traveling gear, which is supplied with brake pressure via at least one brake valve. In accordance with the invention, the brake valve can be actuated electrically, wherein it is connected with a control element via an electric control line, by means of which an operator can brake the traveling working machine.

An improved system for braking an agricultural vehicle propelled by a hydrostatic drive unit is disclosed. An operator provides a desired speed command from a first user interface, such as a joystick. The joystick generates a command responsive to the deflection and communicates the command to a controller. The agricultural vehicle also includes a second user interface, such as a brake pedal. The brake pedal includes a transducer configured to generate a signal corresponding to a deflection of the brake pedal which is also communicated to the controller. If the operator presses the brake pedal when the joystick is commanding motion, the controller reduces the signal from the joystick. The amount the signal is reduced increases as the deflection of the brake pedal increases until the brake pedal overrides any speed command from the joystick.

The present disclosure is directed to a braking system for a work vehicle having hydraulically-actuated brakes. The braking system includes a primary release valve, a secondary release valve, and at least one braking mechanism having one or more brake springs. The braking mechanism(s) is hydraulically coupled to the primary release valve and the secondary release valve via one or more hydraulic lines. As such, during full-power operation of the work vehicle, when the brakes are to be released, the primary release valve is energized so as to overcome a valve biasing spring, thereby shifting the primary release valve so as to direct pressurized hydraulic fluid to the braking mechanism(s). Further, when the brakes are to be applied, the primary release valve is inactive so as to allow the hydraulic fluid to flow away from the braking mechanism(s) to a primary reservoir such that the one or more brake springs compress the braking mechanism(s). Alternatively, when power is lost to the work vehicle, the secondary release valve bypasses the primary release valve and directs pressurized hydraulic fluid to the braking mechanism(s) to release the brakes.
