A splined shaft includes splines evenly distributed over the periphery, wherein the splines being spaced apart from each other. At least one portion of the splines are spaced apart by a modified pitch p with respect to the nominal pitch pn of the splines. The ratio of the absolute value of the difference between the modified pitch and the nominal pitch, to the nominal pitch, i.e. |pn−p|/pn, is different from zero, for example between 0.5 and 5%.

A power assembly and a vehicle in the field of driving technologies are provided. The power assembly includes a housing, a first rotating shaft, a second rotating shaft, and a preloaded part. The first rotating shaft is located in the housing by using two bearings, the second rotating shaft is located in the housing by using one bearing, and the second rotating shaft can slide in an axial direction. A first coupling portion is disposed on the first rotating shaft, a second coupling portion is disposed on the second rotating shaft, and the first coupling portion is coupled to the second coupling portion, so that the first rotating shaft and the second rotating shaft rotate synchronously.

A steering column has a housing. A steering spindle jacket is disposed within the housing. An outer steering spindle is disposed within the steering spindle jacket and has a spline hub. An inner spindle is disposed within the outer steering spindle and includes a spline shaft configured to permit axial movement and prevent rotation of the outer steering spindle when the spline hub and the spline shaft are engaged. In a non-stowed state the spline shaft and the spline hub are engaged and in a stowed state the spline shaft and the spline hub are free of engagement. A pin is disposed in the housing engages the spline hub portion in the stowed state and prevents rotation of the outer steering spindle and is free of engagement in the non-stowed state.

Example torque tube assemblies for use with aircraft high lift devices are described herein. An example apparatus includes a spline coupling having a first yoke, a sliding splined shaft having a second yoke and a torque tube having a first end and a second end opposite the first end. A first fitting with a third yoke is coupled to the first end of the torque tube, and a second fitting with a fourth yoke is coupled to the second end of the torque tube. The third yoke is coupled to the first yoke to form a first U-joint, and the fourth yoke is coupled to the second yoke to form a second U-joint. The spline coupling is to be coupled to a first high lift device drive shaft and the sliding splined shaft is to be coupled to a second high lift device drive shaft.

A torque transmission shaft is configured having increased coupling strength between end joints and a cylindrical member to achieve high transmission torque. Misalignment and disengagement of outer collars (connection members) is effectively prevented in the step of press fitting the torque transmission shaft to another component, such as a constant velocity joint. Circlips are fitted in annular grooves formed in the end joints. The circlips abut and lock the outer collars. The outer collars each include a smaller diameter portion, and an end surface of the smaller diameter portion includes a plurality of hollow portions. The hollow portions allow a clearance between a serrated portion and the smaller diameter portion to communicate with the exterior of the outer collar. Air bubbles contained in an adhesive are allowed to escape out of the clearance through the hollow portions, and thus the clearance is filled with the adhesive densely.

A spindle sleeve and washer for adjusting the camber, toe, or thrust angle of a vehicle wheel to a desired predetermined angle which allows for use of existing hub and spindle assembly without permanent modification to the vehicle.

A failsafe multimode clutch assembly positioned in a powertrain of a rotorcraft. The clutch assembly includes a freewheeling having a driving mode in which torque applied to the input race is transferred to the output race and an overrunning mode in which torque applied to the output race is not transferred to the input race. A bypass assembly has an engaged position that couples the input and output races of the freewheeling unit. An actuator assembly uses pressurized lubricating oil to shift the bypass assembly between the engaged position and a disengaged position. A lock assembly enables and disables actuation of the bypass assembly. In the disengaged position, the overrunning mode of the freewheeling unit enables a unidirectional torque transfer mode of the clutch assembly. In the engaged position, the overrunning mode of the freewheeling unit is disabled such that the clutch assembly is configured for bidirectional torque transfer.

A spindle with a mechanism for transferring axial force from an inner drive assembly to an outer drive assembly. The spindle's inner drive shaft is connected to an inner member of a dual-rod pipe by a drive rod having a sliding sleeve. The sleeve is fixed rotationally with the drive shaft, but not axially. When axial force drives the drive rod toward the drive member of the spindle, the sleeve contacts a stop member which is paired to the outer drive assembly. The stop member may be a pair of dowel pins. Axial force is thereby transferred from the inner member to the outer member, allowing such forces to be absorbed by the outer member's larger drive components.

A power transmission shaft comprises a shaft unit interposed between first and second shafts; an engaged portion provided on one end of the second shaft and having an annular stepped part provided between a smaller diameter portion and a larger diameter portion; and an engaging portion provided on one end of the shaft unit and joinable with the engaged portion to rotate together about a common rotation axis, wherein the engaging portion comprises a cylindrical base portion that rotates together with the shaft unit, an elastically shrinkable cylindrical portion that is provided on one axial end of the cylindrical base portion to project toward the engaged portion and catching pawls that are provided by the elastically shrinkable cylindrical portion and latchingly engageable with the annular stepped part when the engaged portion and the engaging portion are coaxially arranged and joined with each other.

The invention relates to a drive unit (10) for a vehicle, comprising an electric machine (12) having a rotor shaft (14) and a transmission (16) having a transmission shaft (18). According to the invention, the rotor shaft (14) and the transmission shaft (18) are interlocking and coupled by means of an interlocking toothing (44), wherein a lubricant channel (46) is formed in the transmission shaft (18), which feeds into an inner space (48) of the rotor shaft (14) at the end facing the rotor shaft (14) in order to provide lubricant for the interlocking toothing (44), wherein the rotor shaft (14) has an end side (50) at the axial end facing the transmission shaft (18), on which end side one or more openings (52) are formed, extending from an inner circumference (54) of the rotor shaft (14) bordering the inner space (48) to the outer circumference (56) thereof, such that the lubricant channel (46) is fluidically connected to the openings (52) via the inner space (48) and the interlocking toothing (44).
