摘要： The disclosure relates to a brake release system including a parking brake having a brake chamber. The system includes a regular air supply passage, and an auxiliary air supply passage configured to supply pressurized air to the brake chamber for releasing the parking brake. A valve device is provided in the auxiliary air supply passage, the valve device including an exhaust port. A pressure-responsive element is configured to actuate the valve device and configured to be in fluid communication with the regular air supply passage, such that when pressurized air is supplied through the regular air supply passage then the air activates the pressure-responsive element so as to actuate the valve device to move to a closed first state, and when no pressurized air is supplied through the regular air supply passage then the pressure-responsive element is deactivated to allow the valve device to move to an open second state.

摘要： A military vehicle includes a chassis, an axle, a suspension system, and a driveline. The chassis includes a passenger capsule, a front module coupled to a front end of the passenger capsule, and a rear module coupled to a rear end of the passenger capsule. The axle is supported by the rear module. The suspension system is positioned between the rear module and the axle. The suspension system includes a first gas spring, a second gas spring, a first damper, and a second damper. The first damper and the second damper are cross-plumbed to provide a fluid body roll control function. The driveline is configured to drive the axle. The driveline includes a component having a housing that functions as a structural component of the rear module. The first gas spring, the second gas spring, the first damper, and the second damper are directly coupled to the housing.

摘要： A brake system includes a brake actuator configured to engage a brake to limit movement of a tractive element, an air-to-hydraulic intensifier coupled to the brake actuator where the air-to-hydraulic intensifier is configured to receive a supply of air and provide a hydraulic fluid to the brake actuator based on the supply of air to overcome a brake biasing force of the brake actuator to disengage the brake actuator from the brake to permit movement of the tractive element, a hydraulic reservoir coupled to the air-to-hydraulic intensifier, and a valve. The valve includes a first port fluidly coupled to the air-to-hydraulic intensifier, a second port fluidly coupled to the hydraulic reservoir, a third port fluidly coupled to the brake actuator, and a valve gate that is repositionable between a first position that couples the first port to the third port and a second position that couples the second port to the third port.

摘要： A method includes steps for controlling a pneumatic braking system of a trailer vehicle which is connected to a tow vehicle equipped with a hydraulic or pneumatic braking system. At the start of an actuation of the foot brake valve, an electrical switch is closed or opened, and a switching signal is transmitted to an electronic control unit as a braking start signal for an incipient braking process. A brake value sensor detects a brake value representative of the drivers current deceleration request and transmits the brake value to the electronic control unit as a brake value signal. The brake value sensor is used for determining the incipient braking process, and a backup valve is only deactivated by switching a redundancy valve from an open position to a blocking position if the brake value signal detected by the brake value sensor has reached or exceeded a predefined minimum signal value.

摘要： A pre-filling device for a braking system. The pre-filling device includes a pre-filling channel, a pre-filling pressure being inside the channel when the braking system is in a rest and hydro-boost position, and a mechanical valve configured to be opened following a transition from the rest and hydro-boost position to a working position of the braking system; and a hydraulic valve cooperating with the mechanical valve setting the pre-filling pressure inside the channel. The hydraulic valve includes in a first area, facing the mechanical valve, a hole communicating with the channel, and in a second area, hydraulically isolated from the first area, a preloaded resilient element in a chamber held at atmospheric pressure. The hydraulic valve is configured to be connected or not to be connected, by a reciprocating movement inside the channel, to a hydro-booster device and to keep a predetermined pre-filling pressure upon varying of the hydro-boost pressure.

摘要： A valve device for a pneumatically-operated vehicle brake system can adjust the pneumatic brake pressure that can be fed to a brake in a controlled manner. A first variant of the valve device is configured as a modulator for use in an electronically regulated embodiment of the brake system; and a second variant is configured for use in a pneumatically controlled embodiment of the brake system. However, both variants have pneumatic interfaces and mechanical fastening points that are configured substantially identically with respect to one another to facilitate conversion of the brake system from one such embodiment to another.

摘要： Various examples of a controller, method and system for monitoring a tractor-trailer vehicle train are disclosed. In one example a tractor controller is manually-initiated or a user-initiated tractor controller and includes an electrical control port for receiving an electrical sync signal and an electrical start signal, and a communications port for receiving data. A processing unit of the tractor controller includes control logic and is in communication with the electrical control port. The control logic is capable of receiving a data signal at the communications port which includes a time value and a unique identification which corresponds to the towed vehicle in response to the electrical start signal. At a predetermined response time, the tractor controller determines the position of the towed vehicle in the tractor-trailer vehicle train based on the data received from the towed vehicles.
