Abstract
An air circulation cover which provides circulation of air between the inner volume and the external environment and the yoke shaft and the sleeve yoke of the cardan shaft, and prevents the ingress of foreign matter into the inner volume. The cover has a ring-shaped main body providing air passage to the center part, a body support member that seats the main body inside the cover assembly housing, a diaphragm mounted in the center section of body support element, air slots providing air passage located on the body of diaphragm, a wide surface filter element, a filter support element and a body outer edge.
Claims3
An air circulation cover mounted on a cover assembly housing located on a sleeve yoke which ensures bi-directional air circulation between an inner volume, which is formed between a yoke shaft and the sleeve yoke during the operation of a cardan shaft while the yoke shaft and the sleeve yoke are carrying out a sliding motion, and the external environment and which prevents the ingress of water and foreign matter arriving from the external environment into the inner volume, characterized by comprising:
- a main body in the form of a ring which provides air passage;
- a body support element with an opening in the center part of the inner diameter edge which is mounted to said main body from the bottom;
- a diaphragm that is integral with the inner diameter edge at the center portion of said body support element and that is a part of the elastomeric main body;
- at least an air slot that can be formed in different geometries and numbers on the body of said diaphragm according to requirement in order to provide the bi directional air passage;
- an outer edge support element which is integral with the outer edge of the body;
- a large surface filter element in the form of a patelliform cylinder, located on the lower part of the body support element;
- a filter support element mounted to the bottom portion in order to fix and support said patelliform filter element;
- at least an air passage channel allowing air passage in the center part of said filter support element, which can be provided in different numbers and geometries.
