GEARBOX Russian patent published in 2006 - IPC B60K17/08 F16H63/20 

FIELD: automotive industry.

SUBSTANCE: proposed gearbox contains great number of gears forming step up and down stages. Each set is formed by transmission gear fixed on shaft and installed for connection with shaft through sliding gear. Each end outlet mechanism is firmed by end outlet member (101, 102, 103, 104 - which are clutches) and connected with it by shifter fork (105, 106, 107, 108). Shifter forks (105, 106, 107, 108) are arranged on shaft 109 for axial travel. Transmission stages are engaged by connecting sliding gear with carrying shaft by means of end outlet member (101, 102, 103, 104). End outlet mechanism is set into action by end actuating mechanism. Sequence of speed changing is not set in end actuating mechanism. End actuating mechanism contains at least one main actuating member III - shifter pin, which comes into active engagement with end outlet members 101, 102, 103, 104. Possibility of engagement of one transfer stage by means of first end outlet mechanism is provided. And then at least one main actuating member can come into active engagement with other end mechanism without disengagement of stage preliminarily shifted in. Each actuating mechanism contains at least one auxiliary actuating member (113, 116, -thin cams). Description of automobile with such gearbox is provided. Proposed invention provides gearbox in which sequence of speed changing in end actuating mechanism is not set, time of speed changing is considerably reduced and safety is increased.

EFFECT: simple design of gearbox with minimum possible number of parts, ease of control without additional safety precautions.
