Embodiment Construction

[0038] The following will address issues such as figure 1 The invention is described in a vehicle in the form of a truck 10 in the form of a truck. The truck 10 should be considered as an example of a vehicle that may include axles and / or kits in accordance with the present invention.

[0039] However, the present invention may be implemented in many different types of components. Merely by way of example, the present invention may be implemented in a vehicle such as a truck, tractor, car, bus, work machine such as a wheel loader, or any other type of construction equipment. However, the invention can also be used for components not related to the vehicle.

[0040] figure 1 The vehicle 10 includes a number of components in which an axle fits over an axle receiver. to this end, figure 2 An embodiment is shown schematically in which the lower control arm 12 is connected to the steering knuckle 14 via a shaft 16 . exist figure 2 In the embodiment shown in , the shaft 16 ...

Abstract

A shaft adapted to be at least partially inserted into an opening (24) of a shaft receiver (14). The shaft (16) has an axial extension in the axial direction (A) and comprises, in the direction in the axial direction towards the end of the shaft, a nominal shaft portion (28) adapted to be at least partially inserted into the opening of the shaft receiver, followed by an intermediate shaft portion (30), followed by a guide shaft portion (32) in which the shaft terminates. The shaft has a central axis (C) extending in the axial direction and located at the center of a cross-section perpendicular to the axial direction of the nominal shaft portion. The central axis extends in a direction from the nominal shaft portion toward the guide shaft portion. The shaft includes a cross-section having a cross-sectional profile (34) in a plane including the central axis, the cross-sectional profile including a nominal shaft portion profile (36) of the nominal shaft portion, an intermediate shaft portion profile (38) of the intermediate shaft portion, and a guide shaft portion profile (40) of the guide shaft portion. The cross-sectional profile includes a radial direction (R) perpendicular to the central axis, where in the radial direction the nominal shaft profile is located at a nominal radial distance (R0) from the central axis.

Description

technical field [0001] The present invention relates to a shaft adapted to be at least partially inserted into an opening of a shaft receiver. Furthermore, the present invention relates to a kit comprising a shaft and a shaft receiver. Furthermore, the present invention relates to a vehicle. Background technique [0002] In many applications, it is desirable to insert the shaft at least partially into the opening of the shaft receiver. In order to obtain a tight fit between the shaft and the shaft receiver, the cross-sectional area of ​​the shaft is generally similar to the cross-sectional area of ​​the opening of the shaft receiver. However, the similarity in cross-sectional area can be associated with challenges when assembling the shaft and shaft receiver, ie when inserting the shaft at least partially into the shaft opening. An example of such a challenge might be the so-called "sticky drawer effect", where the shaft is stuck in the opening before reaching its proper ...
