Problems solved by technology

In the case of a shift force assist device designed for correspondingly high shift dynamics, there is of course the risk that the shift force assist device will be overcontrolled when the selector lever is actuated with less power. and in this way cause internal shocks or vibrations, and / or cause shocks or vibrations on the gear lever

Embodiment Construction

[0026] The shift force assist shown in the drawing has three basic functional units, namely a housing structure 1 , an input unit 2 and an output unit 3 surrounding this input unit 2 . In this case, the input unit 2 and the output unit 3 are movable relative to each other and relative to the housing structure 1 along the axis 4 .

[0027] The housing structure 1 essentially consists of three parts, namely a housing block 5 , a profile tube 6 and a closure cover 7 . In this case, the profile tube 6 is accommodated sealingly between the housing block 5 and the closure cover 7 , for which purpose the end faces of the sealing ring 8 are pressed against the profile tube 6 from both sides.

[0028] The output unit 3 is also constructed in multiple parts by being joined together by the connecting block 9 , the carrier 10 , the pinch tube 11 and the working piston 12 . The connecting block 9 here constitutes the actual output which can be coupled to the selector lever input of the tr...

Abstract

The invention relates to a pneumatic shift force assist device for a transmission comprising a housing structure (1) with a compressed air inlet (24) and a ventilation opening (48), a control rod (17) and an output unit (3) comprising a working piston (12) defining two pneumatic working spaces (14, 15). In this case, a valve device ( 23 ) is functionally provided between the control rod and the output unit, which valve device ( 23 ) leads to a pneumatic follow-up control of the output unit relative to the control rod by corresponding loading of the two pneumatic working spaces. , and the valve device (23) comprises two valve pistons (20, 21), two annular sealing edges (43), two valve slides (30, 31) cooperating with the sealing edges (43) and two Seats (26, 27). At least one of the valve pistons is assigned a throttle slide (51) movable relative thereto, which has a closing edge (58) cooperating with a correspondingly assigned valve seat and delimiting at least one throttle. A flow channel (49), the cross-sectional area of ​​which depends on the relative position of the throttle slide relative to the correspondingly assigned valve piston.

Description

technical field [0001] The invention relates to a pneumatic shift force assist device for a transmission, comprising a housing structure with compressed air inlets and vents, a control rod movable along its axis on the input side, and a control rod parallel to the control rod surrounding the control rod Rod-movable output unit comprising a working piston guided sealingly within a housing structure delimiting two pneumatic working spaces, wherein functionally between the control rod and the output unit and flow-technically A valve arrangement is provided between the compressed air inlet and the pneumatic working space, said valve arrangement being actuated accordingly by the two pneumatic working spaces, resulting in a pneumatically actuated control of the output unit relative to the control rod. Background technique [0002] Pneumatic shift force assist devices of the aforementioned type are used in particular in trucks. For the driver of the vehicle in question, the pneuma...
