Problems solved by technology

[0004] However, the use of deep grooved rims made of steel was not successful because the space conditions at the drive axle with Ackermann steering did not allow the use of disc brakes (preferably, disc brakes actuated by compressed air)
This is because, compared to multi-part detachable rims, which usually have a flat rim bottom, due to their demountability, sufficient accommodation space for disc brakes, dimensioned according to the conditions of use of the individual vehicle, is within the deep grooved rim made of steel Cannot be used radially, with the added difficulty that conventional 25-inch tires require exceptionally deep grooves to fit

Embodiment Construction

[0018] According to the drawings, the invention relates to a drive axle with Ackermann steering. In this respect, the middle part of the axle (usually comprising the respective different axles) has axle guards at its two ends, the axle guards have an upper guard end 1' and a lower guard end 1", at these ends, The knuckle 2 is arranged steerably about a pivot S predefined by the guard ends 1' and 1", the knuckle shaft 3 of which is integrally connected to the knuckle yoke 3'. The knuckle shaft 3 is configured as a hollow body and accommodates a drive shaft part 4 in the axial center hole, wherein the drive shaft part is connected in the driving direction by a coupling joint 5 to a drive shaft 6 provided in the central shaft part , the connection head is set in the free space between the steering knuckle yoke 3' and the guard ends 1' and 1". The hub device 8 passes through the roller bearing (especially the tapered roller bearing 7) at the steering knuckle shaft 3 is rotatably ...

Abstract

The invention relates to the wheel side of a drive axle with wheel member steering. A drop centre rim, preferably made of steel, is provided on the wheel hub and is combined with a disc brake, which is axially inwardly offset relative to the wheel plane and which preferably has compressed air actuation. The necessary space for the disc brake arrangement is guaranteed by the sufficiently low diameter of the wheel hub in the region of the brake disc and by a comparatively large axial space for the brake system, which is created by an axially narrow design of the wheel hub transmission and a by a new design of the steering knuckle bearing and of the pertaining axle guard.

Description

technical field [0001] The invention relates to a steerable wheel rim for a drive axle of a heavy crane or the like, which has a steering knuckle which is steerably arranged at the axle guard of the central axle part and has a shaft through which the drive shaft part axially penetrates. A passing knuckle shaft, a hub and / or a hub carrier with a hub gear are rotatably supported at the drive shaft part, wherein the hub gear is drivingly connected to the drive shaft part at the input side. Background technique [0002] Axles configured to drive axles and having Ackermann steering for heavy freight vehicles and / or specialty vehicles often have steerable rims of the type originally named. [0003] Such axles are especially used for heavy vehicles, for example, typically for lift trucks with 25 inch tires. In this respect, there has hitherto been a need for multi-part rims which on the one hand can accommodate the typical tires of such vehicles and on the other hand provide suffi...
