A vehicle radiator air intake screen maintenance system comprising a radiator fan, a fan motor; and a processor operable to control the rotational speed and direction of the radiator fan to: periodically implement a drop cycle whereby a radiator cooling air flow generated by the fan rotating in a forward direction is slowed such debris collected on a radiator air intake screen of the vehicle is caused to fall off due to gravitational force; and periodically implement a full reverse cycle where a rotational direction of the fan is reversed and an expulsion air flow is generated whereby debris collected on vehicle radiator and the air intake screen will be blown off, whereafter reverse rotation of the fan is stopped and the fan is returned to the full forward operating speed and direction.

A method for controlling an air conditioning device of an electrified vehicle includes determining, by a controller, whether an active air flap is closed in response to an operation signal of the active air flap of the electrified vehicle, when an electric compressor provided in an air conditioner of the air conditioning device of the electrified vehicle is operated, when the active air flap is closed, controlling, by the controller, opening of an intake door provided in the air conditioning device to increase an amount of internal circulating air of the air conditioner, and when the amount of the internal circulating air of the air conditioner is increased, decreasing, by the controller, a speed of the electric compressor.

A blower device includes an axial flow fan having blades to blow air, and a fan shroud that includes a cylindrical portion surrounding an outer circumference of the fan at a distance from the outer circumference, and an air guiding portion guiding air drawn by the fan. The fan shroud includes a short end part shorter in distance to the outer circumference of the fan than another part in an outer end portion of the fan shroud, and a protruding end part provided at a position advanced in a rotational direction from the short end part, protruding upstream in a flow of the drawn air more than the fan and protruding outward of the air guiding portion. Accordingly, the blower device which includes the fan shroud capable of reducing rotational noise can be provided.

An assembly for improving aerodynamics of a motor vehicle including a movable member forming an active aerodynamic dam positioned at a front end of the motor vehicle and attached to one end of at least one lever, wherein the at least one lever is connected to a motor that powers movement of the movable member, wherein the motor is operatively connected to at least one sensor configured to provide an input to the motor, the motor with a gear selector disposed within the motor that is configured to move a motor gear from a first gear position to a second gear position, resulting in the movable member being disposed in one of a retracted position, a transition position, and a lowered position, based on the received input.

Two cooling fans acting on different heat exchangers may be driven via parallel circuits from a variable displacement hydraulic pump. At least one of the circuits includes a two position valve operable by a control system to vary the flow resistance of the circuit to share the flow between the two fan motors responsive to the relative heat load on the heat exchangers. The pump displacement is controlled to provide a constant hydraulic output pressure irrespective of the operational state of the or each valve assembly.

The invention provides a single radiator cooling system for use in hybrid electric vehicles, the system comprising a surface in thermal communication with electronics, and subcooled boiling fluid contacting the surface. The invention also provides a single radiator method for simultaneously cooling electronics and an internal combustion engine in a hybrid electric vehicle, the method comprising separating a coolant fluid into a first portion and a second portion; directing the first portion to the electronics and the second portion to the internal combustion engine for a time sufficient to maintain the temperature of the electronics at or below 175° C.; combining the first and second portion to reestablish the coolant fluid; and treating the reestablished coolant fluid to the single radiator for a time sufficient to decrease the temperature of the reestablished coolant fluid to the temperature it had before separation.

A bulldozer according to the present application includes a main frame, and an engine, a hood and an exhaust after-treatment device are provided on the main frame, an air inlet of the exhaust after-treatment device is in communication with an air outlet of a turbine of the engine via a pipeline, and the exhaust after-treatment device is fixed to the hood. In the bulldozer, vibration generated by the engine is transmitted to the main frame through an engine supporting frame or a damping device, and then transmitted from the main frame to the hood, the transmission path of the vibration is long, thus the vibration damping becomes complicated and has a high damping value, and the vibration transmitted to the air cleaner is really small.

The present disclosure provides a holder for holding a tube connector for an in-vehicle component. The holder includes a first arm that has a first engaging portion, a second arm that has a second engaging portion, and a fastener. A proximal portion of the first arm is connected to a proximal portion of the second arm at a connection point. The first arm and the second arm are configured to be flexible toward each other by flexing about the connection point. The first engaging portion and the second engaging portion engage with the tube connector by clamping the tube connector therebetween. The fastener fixes the proximal portion of the first arm and the proximal portion of the second arm to a base while biasing the first arm and the second arm toward each other.

A wheel suspension (1) for a wheel (23) of a vehicle, in particular the rear wheel of a utility vehicle, driven by an electric or pneumatic motor (2), having a swing arm (3) which is mounted pivotably around a pivot axis (7) on the vehicle in a first region (4) and is supported on the vehicle in a second region (8), wherein a third region (10) of the swing arm (3) carries a part of the motor (2) which is rotationally fixed in relation to the swing arm (3) in order to transmit a torque to the wheel using a rotating part of the motor (2).
