A bus, notably an electric bus, includes a structure with a wheel housing; at least two wheels in the wheel housing; a seat; and a suspension system connected to the wheel. The suspension system includes a lower arm pivoting about a lower upper longitudinal pivot axis; an upper arm pivoting about an upper longitudinal pivot axis; a gas actuator joined to the upper arm and to the wheel housing. The wheel housing includes a first, a second and a third longitudinal beam which are respectively joined to the lower arm, the upper arm, and the gas actuator.

A suspension system having a knuckle that rotatably supports a wheel end assembly. The knuckle may include a first platform that may have a toe link mount, a second platform that may have a stabilizer bar mount, a brake torque plate that may facilitate mounting of a brake subsystem, or combinations thereof.

A suspension system having a knuckle carrier. A pivot mechanism may pivotally couple a control arm to the knuckle carrier. The pivot mechanism may include a preload nut that may exert a preload force on a bearing assembly. A platform may be fixedly disposed on the knuckle carrier. The platform may support an air spring and may have an arm that is coupled to a stabilizer bar subassembly.

An electric vehicle may include an electric motor, a suspension system, an inverter configured to control the electric motor based on an inverter signal, and a control system. The control system may be configured to receive data indicative a desired torque and data from the suspension system, and determine the inverter signal based on (a) the operator input data and (b) the data from the suspension system, and direct the determined inverter signal to the inverter.

A bus with a low and thin passenger platform adapted for standing passengers, seat places are foreseen as well. The bus is an articulated bus with two or more units. It includes a passenger compartment, left steering modules and right steering modules. Each of these steering modules includes: a wheel with a rotation axis, a steering knuckle with an upper pivot joint and a lower pivot joint, a steering actuator for pivoting the corresponding steering knuckle about the upper pivot joint and the lower pivot joint. The bus further including a passenger platform delimiting the passenger compartment and transversally joining the left steering module and the right steering module, and the passenger platform being vertically disposed, at least partially, between the rotation axes of the wheels and the lower pivot joints.

An emergency egress system for a multi-passenger vehicle such as a school bus (10) includes a housing (30) that operatively supports a ramp (34) in movable connection therewith. Opening an emergency exit door (18) of the bus causes a housing door (24) to open and the ramp to move outwardly from a retracted position toward an extended position. Opening the emergency exit door also causes the suspension of the bus to be automatically lowered to place the emergency exit opening (16) closer to the ground (166).

The present invention provides an independent rear suspension system for low-floor bus for reducing the distance between the floor and ground, offering easy access for passengers and offering a wide space between the wheel arches.

The invention relates to a method for controlling a flow from a source of pressurized air to an air bag of a pneumatic suspension arrangement in a vehicle. The method comprises obtaining a set of vehicle condition signals comprising at least two vehicle condition signals, each vehicle condition signal being indicative of an individual current condition associated with said vehicle. The method further comprises, on the basis of said set of vehicle condition signals, determining whether or not there is a need to supply the air bag with air from the source of pressurized air. The method further comprises, in response to determining that there is not a need to supply the air bag with air from the source of pressurized air, preventing pressurized air to be fed from said source of pressurized air to said air bag.

The invention relates to a method for determining a parameter indicative of a road capability of a road segment supporting a vehicle. The vehicle comprises a plurality of ground engaging members. The method comprises: for each ground engaging member in a sub-set of the plurality of ground engaging members, setting a contact force between the ground engaging member and the road segment; determining a target global load vector to be imparted to the vehicle, the target global load vector comprising at least a vertical load and an inclining moment, determining contact forces for the ground engaging members of the plurality of ground engaging members which are not in the sub-set such that the contact forces for the plurality of ground engaging members together result in a resulting global load vector, a difference measure between the resulting global load vector and the target global load vector being equal to or lower than a predetermined difference measure threshold, applying the contact force to each ground engaging member of the plurality of ground engaging members, for at least one ground engaging member in the sub-set, determining a parameter indicative of the road capability of the road segment associated with the ground engaging member.

A system for adjusting a height of at least one part of a utility vehicle at at least one predetermined location, the utility vehicle having a position determination device and a height adjustment device to determine a position of the utility vehicle and to change a height of the at least one part of the utility vehicle above a ground surface, including: an interface to receive data that indicate a target height of the at least one part of the utility vehicle at the predetermined location; and a control unit that is couple-able to the position determination device and to the height adjustment device, and is configured, based on a determined position, to prompt the height adjustment device of the utility vehicle to adjust the height of the at least one part of the utility vehicle to the target height. Also described are a related utility vehicle and a method.
