Embodiment Construction

[0037] figure 1 and 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 trans...

Abstract

A fixing device (10) for fixing an electric vehicle (100) in a stationary state. The fixing device has a transmission locking device (20) and a differential locking device (40), wherein the transmission locking device (20) has A transmission lock drive (22) with a transmission lock shaft (24) for driving the transmission locking means (26) between the transmission locking position (GS) and the transmission release position (GF), and the differential locking device ( 40) Having a differential lock drive (42) with a differential lock shaft (44) for driving the differential lock between the differential lock position (DS) and the differential release position (DF) Device (46), wherein in addition the transmission locking shaft (24) and the differential locking shaft (44) are connected to each other in a drive-transmitting manner.

Description

Technical field [0001] The invention relates to a securing device for securing an electric vehicle in a stationary state, a method for securing an electric vehicle in a stationary state, and an electric vehicle having a securing device according to the invention. Background technique [0002] It is known that in electric vehicles, as well as in conventionally driven vehicles, the vehicle must be secured in a stationary state to prevent it from rolling away. In vehicles with a manual paddle shift transmission, this is usually provided by engaging first gear. In this case, the parking brake can also additionally take the form of a handbrake to secure the vehicle at a standstill. In automatic transmissions, a separate transmission lock must be installed, 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, the parking brake often al...
