  • Patent number: 11673620
    Abstract: A seal assembly for sealing a lubricant space that is formed between a pin, a track shoe pressed-on onto one end of the pin, and a sleeve of a track. The sleeve is pushed onto the pin and is swivelable on the pin. The track further includes at least one second track shoe pressed onto one end of the sleeve. The seal assembly provides a first seal ring for sealing the lubricant space between the sleeve and the first track shoe, and an elastic ring for applying pressure to the first seal ring. The seal assembly further provides a second seal ring for sealing the lubricant space between the sleeve and the first track shoe and/or the pin.

  • Patent number: 11592110
    Abstract: A seal assembly includes an outer annular case disposed within and coupled with a rotatable outer member to be angularly displace about a central axis. An annular flexible seal is disposed within and coupled with the case to angularly displace about the central axis when the outer member rotates about the axis. The flexible seal has elastomeric sealing lip(s) engageable with an outer circumferential surface of the shaft or of a sleeve disposed about the shaft. An annular inner rigid seal is disposed within the outer case and has an inner end coupled with the shaft or the sleeve, the flexible seal being radially displaceable with respect to the inner rigid seal. An outer annular rigid seal is disposed about the inner seal and has an inner end sealing against the inner rigid seal. A biasing member biases the outer rigid seal against the inner rigid seal.
