Embodiment Construction

[0023] exist figure 1 A transmission or shift transmission 10 for a motor vehicle is shown in block diagram form without a transmission housing, having an input shaft 14 connectable to a drive (not shown) via a separating clutch 12 and an output shaft 16 .

[0024] Between the shafts 14 , 16 are arranged the intermeshing gearwheels of a gear set for six forward gears 1 to 6 and a reverse gear R. FIG. The floating gears of the gear sets 1 to 6 and of the reverse gear R can be shifted in a known manner by means of a synchronous clutch 18 shown only schematically, and thus can be combined with the corresponding fixed gears on the corresponding other shafts 14 , 16 . connect.

[0025] The two-part input shaft 14 of the transmission 10 is connected to one another via a ring gear stage 20 having a larger diameter ring gear 20a with internal teeth and a spur gear 20b meshing with the ring gear, wherein the bearing The sub-shaft 14a of the spur gear 20b carries the gears of the rang...

Abstract

The invention relates to a change-speed gearbox for motor vehicles, in particular manual gearboxes, having a plurality of forward gears and, optionally, one reverse gear, at least one input shaft, an output shaft and, optionally, a layshaft, between which the idler gears, which can be shifted via synchronous clutches, and the fixed gears of the gearwheel sets are arranged. At least one of the shafts (14; 16; 46) has a two-part design and is mounted in the transmission housing with mutually different axes of rotation, an annular gear stage (20) is functionally provided between the sub-shafts (14a, 14b; 16a, 16b; 46a, 46b) and comprises a internally-toothed annular gear (20a) and an externally-toothed spur gear (20b) that meshes therewith, the sub-shaft (14b; 16b; 46b) which has the larger axial distance (a1) to the other shaft (16; 14; 44) bearing gearwheels of the lower forward gears (1, 2) and, optionally, of the reverse gear (R).

Description

technical field [0001] The invention relates to a transmission for a motor vehicle, in particular a shift transmission, according to the preamble of claim 1 . Background technique [0002] US 1 987 897 discloses a transmission with two forward gears, in which ring gear stages are used to achieve different transmission ratios. In this case, either one gear on the layshaft drives directly to the external ring gear, or the other gear on the layshaft drives to a gear through an axially offset shaft and the gear passes through the The shaft is driven to a spur gear that meshes with the internal teeth of the ring gear. The resulting transmission structure is relatively complex, and a transmission with more than two forward gears and possibly a reverse gear is hardly possible. Contents of the invention [0003] The object of the present invention is to provide a transmission of the mentioned type which, with a relatively simple gear arrangement, in particular allows a widening ...
