3.3.2. Design and operation of the mechanism of transmission

Design of the mechanism of transmission
Fig. 3.73. Design of the mechanism of transmission: 1–coupling of a forward course; 2–unilateral coupling; 3–brake of transfer of a backing and low gear; 4–planetary transfer of a forward course; 5–planetary transfer of a backing; 6–tapes of a brake 2–4; 7–coupling of inclusion of a backing; 8–couplings 3–4


The transmission mechanism (fig. 3.73) consists of three pairs couplings, a brake, a tape brake, unilateral coupling and two pairs unary transfers of planetary type. Planetary transfer changes the transfer relation according to vehicle traffic conditions. In the transmission mechanism, hydraulic pressure is transferred from operating valves or solenoids of switching And, In or With (a rabochy cycle) to couplings and brakes.

Coupling of a forward course.
Transfers a torque from a turbine shaft to a forward solar wheel.
Works in a range of a forward course of the first, second or third transfer.

Couplings 3/4.
Transfers a torque from a turbine shaft to back водилу planetary transfer.
Works in a range of a forward course of the fourth or third transfer.

Coupling of inclusion of a backing.
Transfers a torque from a turbine shaft to a back solar wheel.
Works, when the vehicle moves a backing.

Tapes of a brake 2/4.
Blocks rotation of a drum of a backing and fixes a back solar wheel.
Works in the provision of the second or fourth transfer.

Brake of transfer of a backing and low gear.
Fixes rotation of a forward internal gear wheel.
Works, when the vehicle moves a backing or on the first transfer (l range, the HOLD mode)

Unilateral coupling.
Blocks rotation counter-clockwise a forward internal gear wheel on the first transfer.

Planetary transfer.
Planetary transfer works in transmission at the expense of inclusion / switching off of couplings and/or brakes, will transform a motive power of a shaft of the turbine and transfers it to a leading gear wheel of the main transfer.

NOTE
All directions of rotation are considered from the hydrotransformer.
