Problems solved by technology

This can lead to unfavorable rolling behavior of the wheel which, in particular with wide tires or double tires, can lead to irregular tire wear (Reifenverschlei β) on the inside of the wheel or on the inner wheel of the double tire, This shortens the life of the tire overall

Embodiment Construction

[0020] exist Figure 4 shows schematically a non-steering rigid axle 1 according to the invention, which is manufactured in such a way that the left and right vehicle wheels 2, 3, which here are respectively formed by double tires, are aligned with the outer wheels The inclination angle (ε>0) is arranged at the rigid axle 1.

[0021] In order to form a positive camber, here, by way of example, the axle 4 of the rigid axle 1 is arched (ie upwards based on the projected plane) such that the wheels of the opposing wheels 2, 3 rotate The axes 5 , 6 intersect each other in the central axle region 7 and accordingly enclose an angle greater than 0° with one another. Alternatively or additionally to this it can be provided (but not shown) that the wheel bearing seat on the side of the rigid axle is machined such that the wheel bearing seat is inclined relative to the horizontal corresponding to the defined camber angle.

[0022] If the vehicle and thus the rigid axle 1 are now loaded...

Abstract

The present invention relates to an axle construction for a vehicle, in particular a commercial vehicle, wherein the construction has an unguided rigid axle (1) for directly or indirectly carrying vehicle wheels (2, 3). According to the invention, the rigid axle (1) is formed such that the vehicle wheels (2, 3) are arranged at a positive camber angle on the rigid axle when the axle (1) is unloaded.

Description

technical field [0001] The invention relates to an axle arrangement for a vehicle, in particular for a commercial vehicle, according to the preamble of claim 1 . Background technique [0002] The use of rigid axles is generally known in connection with commercial vehicles such as trucks or buses. This rigid axle connects the wheels (Rad) of the axle (Achse) and keeps the track (Spur) and camber (Sturz) constant. For this purpose, rigid axles with double tires or very wide single tires are particularly advantageous, since wheel load fluctuations caused by lateral forces are eliminated by means of such double tires or such wide single tires. become relatively small. Specifically, such non-steering (ungelenkt) rigid axles with double tires or wide single tires, as they are used on heavy commercial vehicles, are constructed and machined without camber. In this case, the right and left wheel planes are parallel to one another when there is no load, as is schematically and exem...
