Embodiment Construction

[0035] figure 1 and 2 An example of an actuator unit arranged for adjusting a component to be actuated of a manual gearbox is shown. For example, this could be a gear selector fork.

[0036] The actuator unit has a base plate 10 on which a plurality of actuators 12 are arranged. The actuators are arranged in pairs opposite one another and act on a common actuator rod 14 .

[0037] Each actuator is a cylinder housing 16 (see also image 3 ) hydraulic cylinder, the piston 18 is arranged in the cylinder housing 16 . The piston is connected to the actuator rod 14 .

[0038] By applying hydraulic pressure on one side of the piston 18, the actuator rod 14 can be actuated in the desired manner.

[0039] A sensor 20 is provided, which is arranged directly adjacent to the cylinder housing 16, so that information about the position of the piston 18 and thus the actuator rod 14 is available to an electronic control system (not shown here). The sensor 20 may be a Hall sensor that r...

Abstract

The invention relates to an actuator unit for a vehicle gearbox, with a baseplate (10), a plurality of actuators (12) which are mounted on the baseplate (10), a plurality of sensors (20) which are assigned at least to some of the actuators (12), and a flexible printed circuit board (24) on which the sensors (20) are mounted, wherein the flexible printed circuit board (24) is provided with a plurality of latching elements (26) with which it is fixed on the baseplate (10).

Description

technical field [0001] The invention relates to an actuator unit for a vehicle gearbox. Background technique [0002] The actuator unit contains a plurality of actuators with which the components to be actuated (for example a selector lever provided with a selector fork) can be individually adjusted. Shifting of the vehicle gearbox (in the example above, gears can be engaged or disengaged) can thus be performed in a desired manner. [0003] The actuator can be a small hydraulic cylinder with which hydraulic pressure can be converted into a lifting motion. Here the piston is arranged in the actuator and can be adjusted in the cylinder housing of the actuator. [0004] In order to activate the actuator it is advantageous to have information about the position of the piston. For this purpose, it is known to arrange a sensor on the actuator, which generates a position signal which depends on the position of the piston. [0005] The sensor can be a hall sensor and the magnet ...
