Abstract
Linear actuator comprising a housing () consisting of two parts (), an electric motor () with a motor shaft, a transmission (-) in connection with the motor shaft, a spindle unit in connection with the transmission, where the spindle unit comprises at least a spindle () with a spindle nut () and where the spindle () is equipped with a bearing (), an adjustment element () in connection with the spindle unit. The linear actuator is characterized in that a mounting unit () is embedded in the housing, said mounting unit () has a front and a rear end, and where the motor () is placed on the rear end of the mounting unit () and the spindle () is mounted on the front end of the mounting unit (), and where the transmission (-) is located inside the mounting unit (). In addition to being able to reduce the number of components with this construction, e.g. the activation element (), the front mounting () and the spindle nut () can be moulded as one single plastic unit, it also allows for a slackening of the tolerances as the assembly of the components is considerably simplified, namely only with regard to the mounting unit (). In that connection, the transmission (-) is expediently placed in the mounting unit ().
