The invention concerns a suspension device for a tracked vehicle, comprising a track assembly (10) at the side of a centre beam (14), comprising a track support beam (20), two wheels (21, 22), several support wheels (23) and an endless track (11) that runs in a plane of rotation (A, A), a first suspension mounting with which the support wheels (23) are suspended at the track support beam (20) in a manner that allows pivoting, a second suspension mounting comprising a combination of a first spring strut (25A) and a first pendulum arm (26A) and a second spring strut (25B) and a second pendulum arm (26B) with which combinations the centre beam (14) of the chassis is spring-damped at a forward and rear end of the track support beam (20). According to the invention, a first pendulum arm (26A) is located in front of the second pendulum (26B), each pendulum arm (26A, 26B) is fixed at its first end in a manner that allows pivoting at a first joint (27, 27) the centre beam (14) of the chassis and at its second end at a second joint (28, 28) at the track support beam (20), each spring strut (25A, 25B) is fixed at one of its ends (30, 30) in a jointed manner at the centre beam (14) of the chassis and at its second end (31, 31) is fixed in a jointed manner at a pendulum arm (26A, 26B), the pendulum arms (26A, 26B) pivot in a plane-parallel manner with the planes of rotation (A, A) of the track (11).

Drive systems of the present disclosure include a drive member and a stationary counter-toothing arranged along a transport path. The drive member has an endless chain for mutual engagement with the counter-toothing to transmit a driving force, and at least one drive pinion for mutual engagement with the chain and for driving the chain. Guide components are provided at the chain. The drive system may further include a guide element for guiding the guide components of the chain.

A work vehicle may include an engine, a drive train driven by the engine, and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further include a temperature sensor configured to sense a track temperature of the at least one track and a vehicle control system configured to receive the track temperature and to determine misalignment of the at least one track based at least in part upon the sensed track temperature.

A track assembly (15) for a track-driven vehicle, whereby the track-carrying beam (15) is arranged to hold a front and a rear wheel (16), one of which is driving, a plurality of carrying wheels about which wheels a continuous track travels, the track-carrying beam (15) is elongated and terminated by a first and a second gable end. The track-carrying beam (15) comprises an integrated compartment (37) and an opening (36) in one (35) of said gables, whereby the compartment (37) communicates with the surroundings via said opening (36), and whereby the opening (36) is arranged to allow for insertion of a transmission device for driving of said driving wheel (16) via the opening (36) in the compartment (37).

A drive arrangement in a vehicle having front and rear ground engaging means and steering means, has a differential transmission, a differential lock, a planetary final drive on each side of the vehicle and a motor acting onto one member of the planetary final drives. The motor is controlled depending on the steering angle such, that it provides for a difference in the drive speed on the left and the right side.

A vehicle including at least one wheel and at least one hub assembly associated with the at least one wheel. The at least one hub assembly includes a hubcap. The hubcap has a transparent body configured for housing a lubricant, a fill port, and at least one continuous indication feature such that a lubricant volume is indicated in any orientation of the hubcap.

The invention relates to a tracked vehicle (11) comprising a vehicle body (30), at least one track assembly (21) and a suspension device (S). Said track assembly (21) is arranged to be supported by said vehicle body (30) by means of said suspension device (S), said track assembly comprising a track support beam (22) for supporting a plurality of road wheels (23, 23a), an endless track (25) being disposed around said road wheels. Said suspension device (S) comprises a bogie arrangement (50) rotatably attached to a fastening point (P0) of said vehicle body (30) about an axis of rotation (Z0) transversal to the longitudinal extension of said track assembly (21) and attached to said track support beam (22) in connection to at least two fastening points (P1, P2) so that the track support beam (22) is allowed to rotate in a rotational plane extending along the longitudinal extension of said track support beam (22) about said axis of rotation.

A standard component of a vehicle equippable with a plurality of wheels or a plurality of track systems for engaging the ground, such as an axle housing or a frame of the vehicle, comprises a connector dedicated to connecting a given one of the track systems to the vehicle and provided during original manufacturing of the standard component of the vehicle. This may facilitate installation of the track systems on the vehicle.

A wall surface suction-type travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The first and second travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the first and second travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular both to a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the first and second travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.
