Abstract
In a center bearing and support mechanism for a two-piece propeller shaft, a center bearing surrounded by an insulator is supported at one of axially separated portions thereof on a frame of a vehicle chassis and at the other of the axially separated portions on a vehicle body so that vibrations of the propeller shaft are transferred through two paths to the vehicle body to be counterbalanced.
Claims6
A center bearing and support mechanism comprising:
- a propeller shaft;
- a center bearing mounted on said propeller shaft;
- a frame constituting a vehicle chassis;
- a vehicle body resiliently supported on said frame;
- first support means interposed between said center bearing and said frame for resiliently supporting the former on the latter;
- and
- second support means interposed between said center bearing and said vehicle body for resiliently supporting the former on the latter.
In an automotive vehicle, a combination of a vehicle chassis having a frame, a vehicle body resiliently mounted on said vehicle chassis, a two-piece propeller shaft, a center bearing mounted on said propeller shaft, a resilient member surrounding said center bearing, a first bracket supporting said resilient member upon said frame, and a second bracket supporting said resilient member upon said vehicle body.
A center bearing and support mechanism for a vehicle having a cab and a rear body, comprising:
- a propeller shaft having a center bearing;
- a frame constituting a vehicle chassis, said cab and said rear body both resiliently and independently mounted on said frame;
- a first mount for resiliently supporting said center bearing on said frame;
- and
- a second mount for resiliently supporting said center bearing on said rear body such that the transfer of vibrations from said propeller shaft to said cab is prevented.
