Problems solved by technology

[0005] However, the coaxial design of the motor rotor itself has no locking function, and the switching of the clutch must be used to enable the second drive rod to switch between the same speed and different speed of the first drive rod. The structure is more complicated and the cost cannot be reduced

Abstract

The invention discloses a steering angle superposed drive device which is applied to a steering system of a vehicle. The steering system comprises a first drive rod and a second drive rod which are arranged toward a first axial interval; a drive device comprises a fixing unit which is connected with the first drive rod and is driven by the first drive rod to rotate, a drive motor and a connection unit; the drive motor comprises a motor body which is arranged on the fixing unit, and a motor rotation shaft which is extended in a second axial direction which is different from a first axial direction and can rotate relative to the motor body; the connection unit is connected with the fixing unit, the motor rotation shaft and the second drive rod respectively and is driven by the motor rotation shaft to drive the second drive rod to rotate; and the motor rotation shaft and the connection unit are arranged in different axial directions, so that the motor rotation shaft has a self-locking function, and the manufacturing is simplified.

Description

technical field [0001] The invention relates to a driving device, in particular to a driving device with steering angle superposition. Background technique [0002] An existing steering angle superimposed driving device, as shown in U.S. Patent No. US 7278512, is used to be connected to a steering system of a vehicle, and the steering system has a first drive rod and a The second driving rod, the first driving rod is used to connect a steering wheel, the second driving rod is used to connect a gear set that drives the wheels to rotate, the driving device includes a first driving member connected to the first driving rod, and a second driving member connected to the second driving rod and driven by the first driving member, the first driving member has a first housing connected to and interlocking with the first driving rod, a A motor rotor arranged coaxially with the first drive rod in a housing, and a clutch connected to the motor rotor, the second drive rod has a connecti...
