Tensioning device having a transport securing concept
First Claim
1. A tensioning device for tensioning a traction mechanism of a traction mechanism drive, the tensioning device comprising:
- a housing;
a piston axially displaceably supported within this housing; and
a transport securing element, the transport securing element, in at least one transport position of the tensioning device, being situated transversely to the piston and in abutment with the piston in the housing in such a way that a displacement of the piston in at least one first axial direction is blocked,the transport securing element including a supporting section, a first web area of the supporting section being in abutment with an end face of the piston in the transport position, and a second web area of the supporting section, the second web area extending axially away from the first web area and axially into a recess of the housing, being supported on the housing at least in a radial direction.

Abstract
A tensioning device (1) for tensioning a traction mechanism of a traction mechanism drive, including a housing (2), a piston (3) that is mounted such that the piston can be displaced in an axial direction inside the housing (2), and a transport securing element (4), which in at least one transport position of the tensioning device (1) is arranged in the housing (2) transversely to the piston (3) and in abutment with the piston (3) such that a displacement of the piston (3) in at least one first axial direction is blocked. The transport securing element (4) is provided with a support portion (5), wherein in the transport position at least one first web area (6) of the support portion (5) is in abutment with one end face (7) of the piston (3), and an additional web area (8) of the support portion (5) extending in an axial direction away from the first web area (6) is supported in the housing (2), at least in a radial direction.
