Embodiment Construction

[0042] figure 1 A perspective view of a receptacle 1 fastened to a motor vehicle as part of an actuating element of a transmission emergency release device for an automatic transmission of a motor vehicle is shown in perspective. The receptacle for fastening to the motor vehicle comprises a tongue 2 which is bent relative to a fastening section 3 . The fastening section 3 is fixedly connected to the motor vehicle body 4 , which is welded in the exemplary embodiment shown. A free space is formed between the motor vehicle body 4 and the fastening section 3 , into which the actuating element can be inserted. The receptacle 1 fastened to the motor vehicle is of symmetrical design and has in its center a one-sided opening 5 into which an actuating element can be inserted. The opening 5 on one side is designed as a rectangular gap of the tongue 2 .

Abstract

A transmission emergency unlocking means for an automatic transmission which is mechanically blocked when a park stage is engaged, having a manually actuable actuating element for the mechanical deactivation of the park stage, wherein the actuation element has a receptacle (1, 29) fixed with respect to the vehicle and with a force-transmission element and has an actuating lever (9, 25) which, for the deactivation of the park stage, can be inserted into the receptacle (1, 29) fixed with respect to the vehicle in order to deactivate the park stage by means of the force-transmission element.

Description

technical field [0001] The invention relates to a transmission emergency release device for an automatic transmission that is mechanically locked when a park gear is engaged, having a manually actuatable actuating element for mechanically deactivating the park gear . Background technique [0002] Automatic transmissions for motor vehicles have an operating range which is divided into a plurality of different manually preselectable operating gears, which are referred to as driving speed levels. Park (parking position) and neutral positions also belong to the driving speed level. The driving speed level of the automatic transmission is selected by the driver on the control unit, so electrohydraulic adjustment elements are embedded in the automatic transmission. When the park gear is engaged, the automatic transmission is locked mechanically, so that the motor vehicle cannot be towed in the event of a power failure or a failure of the associated electronic control unit. In o...
