摘要： The invention relates to a working machine vehicle (1) provided with a supporting frame (6) and a pivoted load container (5), wherein the vehicle (1) is configured to allow tilting of the load container (5) from a transport position to a tilted position for dumping of a load from the load container (5), wherein the vehicle (1) is provided with a suspension arrangement (20, 120) configured to reduce transfer of vibrations between the frame (6) and the load container (5) when the load container (5) is in its transport position, wherein the suspension arrangement (20, 120) comprises a spring element (11, 115) and a damper element (9, 10, 11, 109, 110, 112, 113), and wherein the vehicle (1) further is provided with at least one hydraulic hoist cylinder (9, 109) connected between the frame (6) and the load container (5) and arranged to lift and tilt the load container (5) to the tilting position for dumping. The hydraulic hoist cylinder (9, 109) forms part of a hydraulic system comprising a container (11, 112) for hydraulic fluid and at least one conduit (10, 110, 113) that connects the hydraulic hoist cylinder (9, 109) with the container (11, 112) so as to form a flow passage for hydraulic fluid between the hydraulic hoist cylinder (9, 109) and the hydraulic container (11, 112), and wherein the flow passage is arranged to exert a flow resistance to a hydraulic fluid flowing through the flow passage so as to dampen an oscillating flow through the flow passage and thereby form the damper element of the suspension arrangement (20, 120).

摘要： The invention relates to a working machine (1, 101, 201) having a first side (3, 203) and a second side (2, 201) arranged opposite to the first side. The working machine comprising a dump body (30, 130, 230) and a working machine frame (20, 120, 220), and at least one tilting actuator (41, 241). The tilting actuator may arrange the working machine in a load dumping state. The working machine further comprises a first propulsion axle (10, 110, 210) arranged in the first side, and a second propulsion axle (10, 210') arranged in the second side, and a first propulsion axle suspension arrangement (50, 150, 250) arranged between the first propulsion axle and the working machine frame; and a second propulsion axle suspension arrangement (250') arranged between the second propulsion axle and the working machine frame. In the load dumping state the second propulsion axle suspension arrangement is stiff.

摘要： The invention relates to a working machine (1, 101, 201) comprising a working machine frame (20, 120, 220), at least one propulsion axle (10, 110, 210) having an elongated main body (11, 111) comprising a first end portion (112), a second end portion (113) and a center portion (111C) arranged between the first and second end portions, each one of the first and the second end portions being adapted to be equipped with a propulsion hub (14, 114) for driving a working machine propulsion means. The elongated main body has a main body length (MBL) extending from the first end portion to the second end portion. The working machine further comprises a linkarm arrangement (15, 115, 215) pivotably connecting the propulsion axle with the working machine frame such that the roll axis (RA1) of the propulsion axle relative the working machine frame is comprised in the linkarm arrangement. At least the portion of the linkarm arrangement comprising the roll axis is positioned above the center portion of the propulsion axle.

摘要： The invention relates to a dump body for a hauler vehicle, and a hauler vehicle adapted for such a body. The invention also relates to an autonomous, and electric or hybrid, working machine being equipped with such a dump body. The working machine comprises a dump body (30) and a working machine frame (20). The dump body comprises at least one guide portion (300) having a guide surface facing downwards and being arranged at the load supporting end portion, the guide portion being configured to transfer the load of the dump body, and the second end portion (3) of the working machine frame comprises at least one guiding plate (120) arranged to receive the at least one guide portion of a dump body, whereby the guide portion and the at least one guiding plate are arranged such that the dump body is guided towards a centred position on the working machine during a pivotal downward movement towards said working machine frame of the working machine.
