Problems solved by technology

[0002] In the prior art, there are generally two types of wheel drive modes for heavy vehicles: single-stage bridge and double-stage bridge; the so-called single-stage bridge means that the outer end of the half shaft is directly fixed to the wheel hub, and the half shaft directly drives the wheel hub to rotate, thereby driving the tire to rotate The so-called double-stage bridge means that the sun gear, planetary gear, fixed ring gear and wheel side cover are arranged at the outer end of the half shaft, and the wheel side cover is fixedly connected with the hub. The ring gear drives the side cover to rotate, and the side cover drives the wheel hub to rotate, thereby driving the tire to rotate; single-stage bridges and double-stage bridges have their own advantages, and single-stage bridges are generally suitable for traction and transportation road vehicles, while double-stage bridges are generally Applicable to engineering off-highway vehicles; the wheel-side drive mode determines the use of heavy-duty vehicles, which limits the application range of heavy-duty vehicles. In order to improve the versatility of heavy-duty vehicles, the inventor considers designing a single-stage and double-stage drive mode convertible heavy duty vehicle

Abstract

The invention provides a wheel edge transmission structure of a heavy-duty vehicle. The wheel edge transmission structure of the heavy-duty vehicle is characterized by comprising a half shaft, a wheeledge end cover, a sun wheel, a planetary wheel assembly, a fixed ring gear, a wheel hub, a wheel edge cover and a half shaft sleeve. The wheel edge transmission structure of the heavy-duty vehicle has the technical advantages that the wheel edge driving mode of the heavy-duty vehicle can be switched between two modes, and the versatility of the heavy-duty vehicle is improved.

Description

technical field [0001] The invention relates to a heavy-duty vehicle transmission technology, in particular to a heavy-duty vehicle wheel-side transmission structure. Background technique [0002] In the prior art, there are generally two types of wheel drive modes for heavy vehicles: single-stage bridge and double-stage bridge; the so-called single-stage bridge means that the outer end of the half shaft is directly fixed to the wheel hub, and the half shaft directly drives the wheel hub to rotate, thereby driving the tire to rotate The so-called double-stage bridge means that the sun gear, planetary gear, fixed ring gear and wheel side cover are arranged at the outer end of the half shaft, and the wheel side cover is fixedly connected with the hub. The ring gear drives the side cover to rotate, and the side cover drives the wheel hub to rotate, thereby driving the tire to rotate; single-stage bridges and double-stage bridges have their own advantages, and single-stage bridg...
