Embodiment Construction

[0030] Two embodiments of the invention are shown and described below, simply by way of illustration of two modes of carrying out the invention. The drawings and description are to be regarded as illustrative rather than restrictive.

[0031] The transmission of the present invention now incorporates Figure 1-3 to describe. figure 1 A dependent transmission 10 for a motor vehicle is shown. The transmission includes an input shaft 20 , an output shaft 50 , a first countershaft 30 and a second countershaft 40 . A first drive gear 21 provided at the input shaft 20 is arranged to interact with a first gear 31 arranged on the first countershaft 30 and with a second gear 41 arranged on the second countershaft 40 . The teeth of the gears interact when they fit together, thereby creating torque when rotated. In order to transmit the power / torque provided by the first driving gear 21 to the first gear 31 to the drive wheels of the vehicle, the first countershaft 30 is also provide...

Abstract

The invention relates to a transmission for a motor vehicle, wherein the transmission (10) comprises an input shaft (20) and at least a first and second countershaft (30; 40), and an output shaft (50), wherein the input shaft (20) is provided with a first driving gearwheel (21), which interacts with a first gearwheel (31) arranged upon the first countershaft (30), and a second gearwheel (41) arranged upon the second countershaft (40) wherein the first and second countershaft (30, 40) further is provided with a first and second output gearwheel (32; 42) respectively, which interacts with a common final drive gearwheel (51) arranged upon the output shaft (50). A number of gear teeth (n31) of the first gearwheel (31) is selected such in relation to the number of gear teeth (n21) of the first driving gearwheel (21), that the number of gear teeth (n31) of the first gearwheel (31) can be either reduced or increased with at least one gear tooth, without affecting the number of gears teeth (n21) upon the first driving gearwheel (21), vvhereby the reduction or increase the number of gear teeth (n31) of the first gearwheel (31) is compensated with a profile shift of the gear teeth of the first gearwheel (31).

Description

technical field [0001] The invention relates to a transmission for a motor vehicle and in particular to a transmission with dependent gear steps. The transmission includes an input shaft, at least first and second countershafts, and an output shaft. The input shaft is provided with a first drive gear interacting with a first gear arranged on the first countershaft and a second gear arranged on the second countershaft, and the first countershaft and The second countershaft is also provided with a first output gear and a second output gear, respectively, which interact with a common final drive gear arranged on said output shaft. Background technique [0002] There are several types of transmissions used in vehicles. Transmissions with one input shaft driving either the first countershaft or the second countershaft can have independent or dependent layouts. In a transmission with independent layout, all driven gears on the countershaft are driven by a drive gear on the inpu...
