Problems solved by technology

Although the cylinder is able to control the movement of the two shifting bushes, the independence of said movements from each other cannot be achieved, since the possible movements are fixedly preset at each point of the cylinder and can only be selectively rotated direction

Embodiment Construction

[0052] figure 1 A schematic diagram of a transmission according to a first embodiment of the invention is shown. The drive shaft 1 carries two hollow shafts 2 , 3 which are equipped with gear wheels 4 , 5 or 6 , 7 . The hollow shafts 2 , 3 can be frictionally coupled to the drive shaft 1 via a friction clutch 8 or 9 respectively. On the two hollow shafts 2 , 3 , shift bushings 10 , 11 are mounted in each case in a rotationally fixed and axially adjustable manner. The shifting bushes 10 , 11 , which rotate with the hollow shafts 2 , 3 , are each surrounded by a ring 12 , which is fixed against rotation relative to the housing (not shown) of the transmission, but can move axially. The ring 12 itself is surrounded by a gear 13 coaxial with the drive shaft 1 . The gear wheel 13 can be pivoted around the ring 12 and engages in a groove of the ring 12 by means of pins 14 . Balls 15 are provided in the bore of the gear wheel 13 . The balls 15 each contact on one side a ramp 16 f...

Abstract

A manual shift transmission is disclosed which includes a shaft, at least one loose wheel carried by the shaft and a gear shift sleeve, which is moveable along the first shaft between a gear position coupling the first loose wheel to the shaft and a neutral position allowing a rotation of the loose wheel against the shaft. A gear shift follower is configured to move the gear shift sleeve along the shaft and acts on the gear shift sleeve. An actuating rod can be shifted in the direction of the shaft for shifting the gear shift follower. The actuating rod carries a clutch body which is adjustable between an active position engaging in a recess of the gear shift follower and a passive position sunk into the first actuating rod.

Description

technical field [0001] The invention relates to a transmission, in particular a transmission with a double clutch as known for example from US 2008 / 0134819 A1. Background technique [0002] The transmission comprises a plurality of pairs of intermeshing gears, wherein at least one gear of each pair is designed as an idler gear or a loose wheel, which can be positively coupled to the shaft supporting it by means of a shifting bush, so that through the associated gear pair A torque flow is established between the drive mechanism and the output mechanism of the transmission. In order to be able to generate several gears in a transmission, several gear pairs and correspondingly usually also several shifting bushes are required, which must be movable independently of one another. The adjusting elements required to drive the movements of the different shifting bushes take up installation space, which makes the transmission as a whole relatively compact.
