Problems solved by technology

In a motor vehicle, the installation space for the shift transmission is limited in principle and many additional requirements have to be met, so in terms of the shift mass associated with the transmission elements and the receptacle for transmitting the external actuating force , it is difficult to meet all requirements (especially packaging requirements)

Embodiment Construction

[0020] figure 1 It is a perspective view of a multi-speed shift transmission with a housing 1. The housing 1 has an engine-side end 2 and a driven-side end 3. The housing 1 surrounds the inner cavity of the transmission, and the input shaft, the output shaft, and the countershaft in this embodiment (all covered) are arranged in the inner cavity. These shafts are parallel to each other, and the input shaft and the output shaft are arranged coaxially. These shaft bodies extend from the engine-side end 2 toward the driven-side end 3.

[0021] The input shaft is connected to the engine (not shown) through a clutch, and the output shaft is connected to the driven device 4. A plurality of shift clutches are arranged in the inner cavity, which are used to engage and shift (shift) the gears of the shift transmission. Each shift clutch usually has a sliding sleeve, and shifts through its axial movement.

[0022] It is necessary to use the external operating force acting outside the hous...

Abstract

The invention relates to a transmission for a motor vehicle, comprising multiple gears, a housing (1), an internal space that is surrounded by the housing (1), at least one gear shifting clutch, whichis located in the internal space and via which a gear can be shifted, and a shifting device (10) which functions to direct an external actuation force for shifting, which is acting outside the housing (1), to the gear shifting clutch, wherein the shifting device (10) has at least one internal shifting part located in the internal space, a first introduction element (11a) which engages through a first opening (5) provided in the housing and functions to direct the external actuation force for shifting the gear to the internal shifting part, and a shifting mass (21) arranged outside the housing, which is moved during the shifting of the gear. The invention is characterised in that a connection element (20) that is different from the first introduction element (11a) is provided, with which the shifting mass (21) is connected to the internal shifting part, and the connection element (20) engages into the internal space through a second opening (6) in the housing (1) that is different fromthe first opening.

Description

Technical field [0001] The present invention relates to a shift transmission used in an automobile, wherein the shift transmission includes a plurality of gears, a housing, an inner cavity surrounded by the housing, and at least one switch in the inner cavity for switching A gear shifting clutch and a shifting device for transmitting an external operating force acting outside the housing for switching the gear to the shifting clutch. Background technique [0002] EP 1 686 293 A1 discloses such a shift transmission, for example. The shift device of this transmission has an inner shift member located in the inner cavity of the shift transmission, and a first transmission element for transmitting an external operating force for shifting to the inner shift member. There is also a shift mass (Schaltmasse) arranged outside the housing, which moves during the shift. The inertia of the shifting mass is used to smooth the force peaks that may appear during shifting, that is, during gear...
