Abstract
In this device, which is particularly, but not exclusively, suitable for transmissions for vehicles, an elastomer protecting gaiter comprises a body connected by a fold to a mounting flange and by another fold to a neck portion. The latter comprises a ring forming a bearing, an arrangement for mounting the neck portion in a support, and a sealing device. The body of the gaiter is preferably rigid.
Claims16
A structure comprising in combination a drive unit having an output shaft, a transmission shaft, an articulation interconnecting the output shaft and the transmission shaft, a support device combined with the unit, a protecting device comprising a gaiter of a deformable material which surrounds the articulation, said gaiter comprising a body surrounding the articulation, a mounting flange extending an end of the body, at least one fold interposed between the body and the flange, an elastomeric neck portion extending an end of the body remote from said mounting flange, means rigidly mounting the flange on the unit, the neck portion having a passageway through which the transmission shaft extends and being combined with the support device so as to be supported by and held longitudinally in position in the support device, a bearing mounted on the transmission shaft and held in the passageway of the neck portion with the elastomeric neck portion interposed between the bearing and the support device and engaging the bearing and the support device so that the bearing is resiliently supported, and sealing means in sealing contact with the transmission shaft and connected to the passageway of the neck portion on a side of the bearing remote from said mounting flange.
An assembly comprising in combination a bearing and a protecting device for an articulation including a shaft, the device comprising a gaiter of a deformable material having a body for surrounding the articulation, a mounting flange extending an end of the body, at least one fold interposed between the body and the flange, an elastomeric neck portion extending an end of the body remote from said mounting flange and having a passageway for receiving said shaft and an outer configuration for mounting the neck portion in a support device so as to be held longitudinally in position by the support device, said bearing being held in position in the neck portion and adapted to act as a bearing for said shaft, and sealing means for cooperation with said shaft and located on a side of the bearing remote from said mounting flange.
