Abstract

The invention relates to a transmission assembly comprising a toothed rack (1) and a gear (2) that is linked with a shaft (4) constituting a control cam and that engages with the toothed rack (1). The inventive transmission assembly is characterized in that a stop (5) is provided on the toothed rack (1) and interacts with a projection (6) of the gear (2) or with the shaft (4). The inventive stop substantially simplifies installation of the transmission assembly.

Claims

1. A transmission assembly, comprising

a rack comprising a stop, and

a gearwheel comprising a projection, the gearwheel connected to a shaft so as to form a control cam and engage the rack such that the stop,

cooperates with the projection or the shaft.

2. The assembly according to claim 1, wherein the projection is formed in the toothing of the gearwheel.

3. The transmission assembly according to claim 1, wherein the rack and the gearwheel are produced as plastic injection moldings.

4. A tachograph comprising:

a rack comprising a stop, and

a gearwheel comprising a projection, the gearwheel connected to a shaft so as to form a control cam and engage the rack such that the stop cooperates with the projection or the shaft, wherein the rack and gearwheel are arranged to control a reading stylus.
