  • Patent number: 8127880
    Abstract: According to the present invention mechanical system for tilting cab of a vehicle, the rotational motion of the detachable handle (12) is transmitted to the worm shaft (14) through the engaging clip (15). The worm shaft (14) rotates the worm (11) which in turn rotates the nut (10). The nut (10) being restrained for translational motion, pushes the screw (9) upward. The screw (9) gets a translational motion and is raised. The clevis joint (8) on the top of the screw (9) forces the link arm (7) upwards. The link arm (7) also rotates about the clevis joint (8) due to the revolute joint. The link arm (7) transmits this motion through the bush (13) and the bush bracket (6) to the suspension bracket (3) of the cab (1). As a result the cab (1) tilts about its transverse axis (5).

    Abstract: A truck has a driver's cab tiltably mounted above a drive train and coupled in an articulated fashion to a bottom chassis by a bearing. The drive train is attached to the chassis, and has a restraint system for the driver's cab. In the case of a head-on collision of the truck with an obstacle at the level of the driver's cab, the restraint system serves to absorb and deflect collision forces at the driver's cab. The restraint system includes a flexible coupling element that establishes a connection, which is resistant to tensile stress counter to the direction of travel, between the driver's cab and a front fixed part of the drive train located underneath it.

  • Patent number: 7975793
    Abstract: A foot pod for use with the operator cab of a construction vehicle is designed to pivot separately from the operator cab. The operator cab may be pivoted toward the rear of the construction vehicle and the foot pod may be pivoted toward the front of the construction vehicle. Pivoting the foot pod toward the front of the vehicle permits ground access to the foot pod and any controls carried thereby. Separately pivoting the foot pod forward is particularly advantageous for cleaning the foot pod or servicing any controls carried by the foot pod. Isolation mounts may be used to dampen vibrations from the chassis to the foot pod and the operator cab.

  • Patent number: 7967372
    Abstract: A cab-side cover 10 is fixed to a cab 1, and a chassis-side cover 13 is fixed to a side member 2. A rear edge portion 7a of a tilt stay 7 is located between a front tire 5 and the side member 2 while the cab 1 is in a non-tilted state. The cab-side cover 10 includes a cab-side front cover portion 12, and the chassis-side cover 13 includes a chassis-side front cover portion 15. The cab-side front cover portion 12 is located at the outer side, in the vehicle-width direction, of the tilt stay 7 and extends further forward than the rear edge portion 7a of the tilt stay 7 while the cab 1 is in the non-tilted state. The chassis-side front cover portion 15 is located at the inner side, in the vehicle-width direction, of the tilt stay 7 and extends further forward and downward than the front lower edge of the cab-side front cover portion 12 while the cab 1 is in the non-tilted state.

  • Patent number: 7946370
    Abstract: A work machine includes a frame supported for movement over the ground, a prime mover for driving movement of the frame, an operator compartment supported on the frame and a cradle coupling the operator compartment to the frame. The cradle is pivotable between an operating position and a service position and includes a biasing mechanism for biasing cradle toward the service position and an isolation mount coupling the operator compartment to the cradle. The isolation mount permits deflection of the operator compartment relative to the cradle along a selected axis. A latch mechanism releasably couples the cradle to the frame and a handle is provided for actuating the latch mechanism. The isolation mount includes a deformable member having a void defining the selected axis. The axis can be aligned with a force exerted on the cradle by the operator compartment to reduce stress on the biasing member.

  • Patent number: 7882914
    Abstract: A vehicle for terrain travel includes a chassis, an operator platform including space for footing, a first isolation mechanism and a second isolation mechanism operably connected between the chassis and the operator platform. The isolation mechanisms are to be placed either below, above or level with the operator platform and at substantially opposite edges of the operator platform. Each isolation mechanism at least partially absorbs motion from the chassis. The isolation mechanisms may be made up of telescopic members, a biasing member or a dampening device. One of the isolation mechanisms may provide pivotal coupling of the operator platform to the chassis and at least partially absorb motion from the chassis.

  • Publication number: 20110017536
    Abstract: According to the present invention mechanical system for tilting cab of a vehicle, the rotational motion of the detachable handle (12) is transmitted to the worm shaft (14) through the engaging clip (15). The worm shaft (14) rotates the worm (11) which in turn rotates the nut (10). The nut (10) being restrained for translational motion, pushes the screw (9) upward. The screw (9) gets a translational motion and is raised. The clevis joint (8) on the top of the screw (9) forces the link arm (7) upwards. The link arm (7) also rotates about the clevis joint (8) due to the revolute joint. The link arm (7) transmits this motion through the bush (13) and the bush bracket (6) to the suspension bracket (3) of the cab (1). As a result the cab (1) tilts about its transverse axis (5).

  • Patent number: 7703568
    Abstract: In a coaxial two-wheeled vehicle, an attitude controller (84) calculates motor torque Tgyr for maintaining a base so that it has a target angle from deviation between base angle command ?ref serving as attitude command and current base angle ?0 calculated by using a gyro sensor (13) and an acceleration sensor (14). On the other hand, at a position proportional controller (86R), a differentiator (88R) and a velocity proportional controller (89R), there is performed PD control with respect to deviation between rotation position command Prefr of a motor rotor (92R) for right wheel and current rotation position ?r of a motor rotor (92R). A current control amplifier (91R) generates motor current on the basis of added value of motor torque which is the control result and estimated load torque T1 calculated by using pressure sensors to drive the motor rotor (92R).

  • Patent number: 7673931
    Abstract: The invention relates to a working vehicle which can improve a workability of a maintenance, inspection and the like with respect to a portion around an engine, and can tilt up a rear hood together with a tilt-up floor. An upper side of an engine (not shown) can be covered in a rear end portion side of a floor (35). A hinge mechanism (38) is arranged between a front end portion of the floor (35) and a rev-frame (25), and the floor (35) can be tilted up via the hinge mechanism (38). A rear hood (32) is coupled by hinge to a first support column (15) of a mounting bracket (4) supporting the floor (35), and is structured so as to be freely opened and closed. It is possible to tilt up the floor (35) in a state of attaching the rear hood (32), by canceling a fixed state of the mounting bracket (4) to a supporting and fixing member such as a counter weight (2) or the like.
