Abstract
A rear portal trailing arm assembly for a vehicle rear suspension that includes a CV joint hub for coupling with a transaxle and a wheel hub for coupling with a rear wheel. A gear transfer case extends rearward from the CV joint hub to an axle case and functions similarly to a rear trailing arm. Forward mounts facilitate coupling the gear transfer case to the chassis such that the trailing arm assembly pivots vertically with respect to the chassis. A rearward mount facilitates coupling a strut with the gear transfer case to control the vertical motion of the rear wheel. Multiple gear assemblies are meshed within the gear transfer case. An axle is coupled with the meshed gear assemblies and housed within the axle case, such that torque applied to the CV joint hub is communicated to the wheel hub.
Claims12
A rear portal trailing arm assembly for a vehicle, comprising:
- a CV joint hub for coupling with a transaxle;
- a gear transfer case having a proximal end and a distal end, the CV joint hub disposed at the proximal end of the gear transfer case,
- an axle case disposed at the distal end of the gear transfer case;
- two or more meshed gear assemblies disposed within the gear transfer case;
- an axle coupled to a first gear of the two or more meshed gear assemblies, the axle housed within the axle case, wherein the CV joint hub is coupled to a second gear of the two or more meshed gear assemblies;
- a wheel hub for coupling with a rear wheel;
- a plurality of forward mounts disposed at the proximal end of the gear transfer case, the plurality of forward mounts are integral with the gear transfer case, the plurality of forward mounts configured to couple to a chassis of the vehicle such that the trailing arm assembly pivots vertically with respect to the chassis;
- and
- a rearward strut mount disposed at the distal end of the gear transfer case, wherein the rearward strut mount is configured to couple to a strut of the vehicle to control a vertical motion of the rear wheel.
A rear portal trailing arm assembly for a vehicle, comprising:
- a trailing arm for coupling a rear wheel with a chassis;
- an inboard case disposed at an end of the trailing arm;
- an outboard case for fastening to the inboard case to enclose an interior cavity;
- a pinion gear assembly disposed in the interior cavity and coupled with a drive axle, the pinion gear assembly is longitudinally aligned along a pinion axis;
- and
- an output gear assembly meshed with the pinion gear assembly and coupled with a wheel hub, the output gear assembly is longitudinally aligned along a hub axis, wherein the pinion axis is disposed at an angle relative to the hub axis, wherein the angle ranges from 1-25 degrees.
