Estimating the term…
A vehicle transmission assembly includes a main gear box and an auxiliary or range gear box. An electrical actuation device for effecting changes in the range gear box preferably includes a solenoid actuator associated with each of the range gear members. A switch, which is preferably provided on the shift lever handle, allows the driver of the vehicle to indicate a desire to make a change in the range gear box. The solenoid actuators are responsive to the electrical switch to effect the range shift. The electrical components replace pneumatic components and associated fittings and airlines used with some prior systems. A further feature of this invention is to include a synchronizer protection circuit that disables the solenoid actuators unless prescribed transmission conditions are met.
A vehicle transmission assembly, comprising:
A method of effecting gear changes in a vehicle transmission assembly including a range gear box having a plurality of range gear members and an electrical actuator associated with the range gear members comprising the steps of:
A system for controlling engagement of gear members within a vehicle transmission range box, comprising:
