1. A driven linear axis comprising:
a housing having a linear rail guide with two profile rails on which a carriage is arranged so as to be linearly movable back and forth with the aid of a transport device;
wherein the carriage has a guide body with two lateral track carriages and a multifunctional interface,
wherein the carriage is guided between the two profile rails with the aid of the two lateral track carriages,
wherein the transport device comprises a belt which circulates in the housing and is guided over two gears, at least one gear being configured as a drive gear,
wherein a drive device is set in the drive gear and configured in the form of a modular drive cartridge engaged in a torque-locking rotational connection with the drive gear,
wherein the drive device has an electric motor device and a gear device;
wherein a shaft arrangement with a hollow shaft as an output shaft is provided between the electric motor device and the gear device, said shaft arrangement being rotatably received on a bearing axis of the drive device, said bearing axis being torque-proof with respect to the housing,
wherein an input side of the gear device is connected to the hollow shaft in a torque-proof manner, and
wherein the drive gear is seated radially outwardly on an output side of the gear device and is coupled to the output side of the gear device in a torque-proof manner.
