A tank mounted into an enclosure with insulated sides is assembled into an engine compartment of a construction machine. A fan is coupled to the enclosure to draw air through the enclosure to cool a fluid in the tank, such as diesel exhaust fluid. A discharge pipe is used to exhaust the air from the enclosure external to the engine compartment.

A method of mounting a DEF tank in a recess of a frame of a machine, and such a machine is disclosed. The machine may further comprise a first bracket mounted to the frame, the DEF tank, the fuel tank and a plurality of flexible mediums. The DEF tank is disposed in the recess and may be disposed on top of the first bracket. In an embodiment, the DEF tank is expandable. The fuel tank may be disposed inside the recess. A first portion of the plurality of flexible mediums may be sandwiched between the DEF tank and the frame, and a second portion of the plurality of flexible mediums may be sandwiched between the DEF tank and the fuel tank. Each of the plurality of flexible mediums is configured to constrain the DEF tank from movement that is in excess of expansion of the DEF tank.

The present invention relates to a construction machine, said construction machine comprising a brake assembly for braking the machine, as well as an operator platform. The operator platform comprises at least one operator seat with a total of at least two operating positions for a machine operator at opposite ends of the operator platform, and an actuation device for foot actuation of the brake assembly. According to essential aspects of the present invention, the actuation device for the brake assembly comprises a brake beam which extends transversely to the working direction of the construction machine and which can be operated by foot from said two operating positions, and the actuation device further comprises an actuator for the brake beam, which is arranged below the brake beam.

An electric roller (1) includes: a pair of front and rear compaction wheels (a front wheel (R1) and a rear wheel (R2)); a vehicle frame (2) rotatably supporting the compaction wheels; at least one compaction-wheel electric motor (front-wheel electric motor (M1), right rear-wheel electric motor (M2), and left rear-wheel electric motor (R3)) to drive the compaction wheels; at least one compaction-wheel inverter (front-wheel inverter (J1), right rear-wheel inverter (J2), and left rear-wheel inverter (J3)) to control rotation speed of the compaction-wheel electric motor; at least one battery (K) to supply power to the compaction-wheel electric motor and compaction-wheel inverter; and a control unit (3) to output a signal to the compaction-wheel inverter according to a degree of inclination of a forward-backward lever (17), wherein the electric roller (1) has no internal combustion engine and uses only the battery (K) as a power source for the compaction wheels.

A self-propelled earth working machine includes a machine frame, a working apparatus, at least one function apparatus, a drive system including first and second motors, a function transmission and a working transmission. The working transmission is configured to transmit torque between the drive system and the working apparatus. The working transmission connects the first motor and the second motor to the working apparatus for the transmission of torque such that the working apparatus may be driven to perform the earth working movement solely by the first motor or solely by the second motor or jointly by the first and second motors, wherein the working transmission connects the first motor to the working apparatus at a first transmission ratio and connects the second motor to the working apparatus at a second transmission ratio different from the first transmission ratio.

The description discloses an electric drive train of an off-highway vehicle. The drive train comprising: a drive axle; a gearbox connected to the drive axle, where the gearbox comprises a gear train, where the gear train comprises an input gear, an intermediate gear, a PTO output gear, and a disconnect clutch configured to selectively couple the intermediate gear to the drive axle; an electric motor, where the electric motor is mounted on the gearbox in a longitudinal direction of a vehicle and coupled to the input gear; and a PTO device mounted on the gearbox alongside the electric motor and coupled to the PTO output gear. The off-highway vehicle has one or more auxiliary devices driven by the PTO device. The PTO device may drive the auxiliary devices.
