System for preventing accidental disengagement of a gear of the exchange rate

摘要

"System to prevent accidental disengagement of a gear change" the lock system of a bar of reaction, of the type to be applied in a truck (1),The type that includes a powertrain (10, 20, 12, 13) substantially arranged between the girders, a cabin (3) of the type inclined and an exchange (20) type mechanical.Connected to the control lever (15) positioned inside the cabin (3) of the truck (1) by means of a rod (17).Hinged between the control lever (15) and arm (21) of the drive shaft support (22).The stem (17) with a bar (23) articulated on a first end (26) of the reaction bar (25).The second end (27) of the reaction bar is hinged on the body of the exchange (20).The system comprises a locking device (30), able to cause a mechanical interference, and comprises an actuator (40, 40 '), this actuator comprises a retractable pin (45) which intercepts.In the extended position, the movement of the deflection of the reaction bar (25).
