AI Technical Summary

Technical Problem

In existing propulsion systems, the roller bearings, locking shafts and housings included in the parking brake increase the cost and complexity of the system.

Method used

By installing multiple bearings on the spindle of the system, including the first bearing and the second bearing, it guides the rotation of rotor and lock gears, thereby eliminating one or more dedicated bearing for locking gears.

Benefits of technology

The structure of the propulsion system is simplified, the cost is reduced, and the stability and reliability of the system are ensured through reasonable distribution of the force exerted on the locking gear.

Abstract

The invention relates to a propulsion system (1) for a mobile device, comprising:-a housing (6) defining a motor space (7); -a motor (3) housed in a motor space (7), the motor (3) comprising a stator (22) arranged inside the motor space (7) and a rotor (23) mounted to the main shaft (2) for rotation therewith, the main shaft (2) being guided in rotation about an axis X relative to the housing (6) by a first bearing (24) and a second bearing (25) respectively arranged on both sides of the rotor (23); -a locking gear (50) connected to the main shaft (2) for rotation therewith, the locking gear (50) being adapted and intended to interact with a locking mechanism (51) arranged to assume a locked state in which the locking mechanism (51) interacts with the locking gear (50) to prevent rotation thereof about the axis X, a lock gear (50) is positioned between the first bearing (24) and the second bearing (25).
