Abstract
A joint unit of a control arm of a wheel suspension in a motor vehicle, with a housing (1) and a pivot (2), which is mounted slidingly in the housing by a spheroidal bearing surface (3). The joint unit has a catching device (4) to avoid complete separation of the housing (1) from the pivot (2). The catching device spans over part of the housing (1) in a contactless manner during normal operation. The catching device (4) has at least one flexible catching band or at least one securing strap (4.1, 4.2) with a recess (4.1.1, 4.2.1), into which protrudes a catching pin (1.1, 1.2) of the housing in a contactless manner during normal operation, or at least two securing straps (4.1 and 4.2).
Claims16
A joint unit of a control arm of a wheel suspension in a motor vehicle, the joint unit comprising:
- a housing;
- a pivot with a spheroidal bearing surface, said pivot being mounted slidingly in said housing by means of said spheroidal bearing surface;
- a catching device for avoiding complete separation of said housing from said pivot, which spans over part of said housing during normal operation in a contactless manner said catching device having at least one of
- a flexible catching band,
- a securing strap with a recess (4.1.1, 4.2.1), into which a catching pin of said housing protrudes in a contactless manner during normal operation, and
- two securing straps each having a recess into which an associated catching pin of said housing protrudes in a contactless manner during normal operation.
A motor vehicle wheel suspension control arm joint unit comprising:
- a housing;
- a pivot with a spheroidal bearing surface, said pivot being mounted slidingly in said housing and maintained by said housing in an operative pivoting range;
- a catching device for preventing a separation of said housing from said pivot at a location spaced a distance beyond said operative pivot range, said catching device spanning over part of said housing during operation in said operative pivot range.
