A steering device includes a rotation central portion having a rotation axis Ax of the steering device and a steering unit connected to the rotation central portion. The direction in which the rotation axis of the rotation central portion extends is an axial direction. One of directions perpendicular to the axial direction is a radial direction. A direction perpendicular to the axial direction and the radial direction is a width direction. The steering unit protrudes from the rotation central portion in the radial direction in plan view of the steering device in the axial direction. A maximum width of the steering unit in the width direction is less than or equal to a maximum width of the rotation central portion in the width direction.

A working machine includes a machine body capable of traveling, a working device to be attached to the machine body, a steering handle provided to the machine body and capable of being rotatably operated, an assist grip attached to the steering handle to assist a rotating operation of the steering handle, and an operation tool provided to the assist grip to operate devices provided to the machine body.

The invention relates to a steering device for vehicles, in particular forklifts, for carrying out a steering movement of the drivable vehicle on a surface by manual operation by a vehicle driver, wherein the steering device is attached to or in an armrest of a vehicle seat, wherein the steering device comprises at least one rotatable wheel element which can be at least partially grasped on the circumference by the fingers of a hand of the vehicle driver placed on the steering device and can be rotated about an axis of rotation for a steering movement.

A tiller knob has a top section having a lower periphery with a first plurality of indented segments and a bottom section having an upper periphery with a second plurality of indented segments. When the lower periphery and the upper periphery are mated with one another, the first plurality of indented segments cooperates with the second plurality of indented segments to form separate openings around an outer circumference of the tiller knob. A center section is located between the top section and the bottom section so that outer surfaces of extending segments are exposed through the separate openings. A multi-sectional tiller knob having top and bottom sections formed of a first material and a center section formed of a second material is also disclosed.

A steering wheel spinner is incorporated within an outer steering wheel. The spinner assembly is fashioned as an inner steering wheel secured within the circumference of the outer steering wheel. The inner steering wheel is capable of full 360 rotation relative thereto.

A system for grip-based handwheel compensation includes a net handwheel torque moment determination module that determines a net handwheel torque moment between a left grip and a right grip on a handwheel. The system also includes a filter transition compensation module that applies a filter to smooth transitions in the net handwheel torque moment as a bias compensation. The system further includes a handwheel torque compensation module that determines a grip compensated handwheel torque based on a difference between a sensed handwheel torque and the bias compensation.

A system may include a steering aid device configured to be mounted on a steering wheel of a vehicle having a rim member to aid manipulation of the steering wheel. The aid device may have a hand engagement surface for being engaged by a hand of an operator of the vehicle. The hand engagement surface may have a primary section being substantially planar. The aid device may define a passage for receiving a portion of the steering wheel, and the passage may extend along a passage axis.
