Linearführung

摘要

The invention relates to a linear guide, comprising a carrier body (2) that can be moved along a guide track (1) and a brake device with brake cheeks (3) acting upon the guide track (1) and a piston which is placed in a pressure chamber (5) and can be displaced by a pressure medium of the carrier body (2), whereby the brake device also has a spring (7) acting upon the piston (6). According to the invention, a pressure part is placed on the carrier body (2) which is pressed against one of the brake cheeks (3) located on the guide track (1) by the spring (7) when the piston (6) is not being subjected to the pressure medium. This results in a linear guide whose carrier body can be mechanically and reliably blocked on the guide track in case of emergencies such as pressure medium outage.
