Embodiment Construction

[0037] figure 1 with figure 2 A fastening device 10 according to the invention is schematically shown. This fixture is provided with two separate drives, the transmission lock drive 22 and the differential lock drive 42 . The transmission locking drive 22 and the differential locking drive 42 are each embodied as either electromechanical or hydraulic actuators. A transmission locking device 20 and a differential locking device 40 are thus formed. With regard to the mode of operation, the two shafts (ie the transmission locking shaft 24 and the differential locking shaft 44 ) are now drivingly connected to one another via corresponding coupling sections 25 and 45 . Redundant operation is achieved by the coupling of the transmission lock drive 22 and the differential lock drive 42 .

[0038] At least one of the two drives 22 and 42 is now activated for the imposition of the stationary situation, ie the locking of the driven wheels. During normal driving operation, the tran...

Abstract

A securing device 10 for securing a stationary state of an electric vehicle 100 includes a gearshift interlock device 20 and a differential interlock device 40. The gearshift interlock device 20 has agearshift interlock drive 22 with a gearshift interlock shaft 24 for driving a gearshift interlock 26 between a gearshift interlock position GS and a gearshift release position GF. The differential interlock device 40 has a differential interlock drive 42 with a differential interlock shaft 44 for driving a differential interlock 46 between a differential interlock position DS and a differentialrelease position DF. The gearshift interlock shaft 24 and the differential interlock shaft 44 are connected to one another in a drive-transmitting fashion.

Description

technical field [0001] The invention relates to a securing device for securing a stationary state of an electric vehicle, a method for securing a stationary state of an electric vehicle, and an electric vehicle having a securing device according to the invention. Background technique [0002] It is known that in electric vehicles and also in normally driven vehicles, the vehicle must be secured against rolling away when stationary. In vehicles with a manual shift transmission, this is usually provided by engaging first gear. In this case, the parking brake can additionally also be secured at rest in the form of a hand brake. In automatic transmissions, a separate transmission lock must be inserted, which is also known in automatic transmissions as the park position with the symbol "P". However, when the vehicle is parked in an inclined parking position, that is to say for example on a slope, it is usually also necessary to additionally use the parking brake as a friction-f...
