MCPP, advantages and disadvantages of the mechanical gearbox

Manual gearbox (transmission) - variation of the gearbox, a system designed for step-by-step transmissions, where the transmission selection is performed by the driver manually. The checkpoint ensures the use of the optimal mode of operation of the motor when driving under different conditions. In the manual transmission, this is done with manual gear shift, which have a different gear ratio.

MCPP, how the mechanical gearbox is arranged

MCP consists of such components:

  1. Switching lever.
  2. Switching mechanism steps with locking and locking devices.
  3. Synchronizers.
  4. Secondary, intermediate and primary shafts with gears.
  5. Carter.
  6. Additional shaft.
  7. Reversing gears.

The switching mechanism of the steps is designed to change the gear in the box. It controls the driver from the car's salon with the lever. The locking device, while protects against the simultaneous inclusion of two gears, and the locking device does not allow the transmission spontaneously turns off.

Synchronizers are needed for impact, silent and smooth inclusion of steps, by adjusting the angular velocities of gears that rotate.

Transmission shafts are rapid in bearings that are installed in the crankcase, and are distinguished by the presence of gear sets with a variety of teeth.

Carter contains the main elements and gearbox nodes. It is fixed on the clutch crankcase, which, accordingly, is attached to the motor. Since in the process of the gear gear, the gearbox is subjected to considerable loads, they need a good lubricant. That is why the crankter is flooded with transmission oil half of its volume.

Principle of operation of the mechanical gearbox

When the control lever is in a neutral position, the torque from the motor drive wheels is not transmitted. During the movement of the control lever, a specific plug moves the clutch of the synchronizer. The coupling itself provides synchronization of angular velocities of the corresponding slave and gear.

Next, the gear gear is cloured with a gentle crown of the clutch, which provides the gear lock on the slave shaft. The checkpoint transfers the torque from the "engine" to the drive wheels with the assigned gear ratio.

Transport traffic with reversal provides the appropriate box transfer. The change in the direction of rotation is made due to the intermediate gear of the reverse, which is installed on a separate axis.

Robotic gear shift boxes

The basis of the design of the robotic gearbox is taken by MCPP, more reliable than automatic transmission. It adds special devices that are responsible for clutching and switching steps.

An ordinary mechanic provides clipping and switching the transmission directly by the driver manually, focusing on the situation on the road. In the case of a robotic checkpoint, the developers exclude a motorist from this chain and trust all the actions of automation and computer. With the installation of assets-evacuators, it was possible to automatically switch the RCPP.

The RCPP combined positive moments both mechanics and automaton - ease of repair, fuel efficiency and other with the possibility of movement in authoreme without the use of clutch pedal. In addition, while the possibility of manual control is preserved through the lever or stealless switches for the principle of tiptronic.

It is worth saying that the robot box has several advantages:

  1. High reliability in comparison with the visor and machine gun.
  2. The working volume of the RCP is significantly less than automatic transmission, therefore, the amount of oil used is also less.
  3. The grip of the RCP is characterized by the presence of an increased by thirty percent of the resource.

  4. In fact, all variations of the RCPP have the option of manual switching of steps (the principle of the tiptronic).
  5. Compared by automatic and variator, RCPP is cheaper in repair and production.
  6. RCPP weighs much less than automatic transmission, which makes it possible to install on small transport.

  7. Reducing the fuel consumption under equal conditions in comparison with the use of other types of checkpoints.

However, despite all the advantages, the Robot has several drawbacks:

  1. The RCPP with an electrical servo is distinguished by the presence of a significant switching delay, which reaches two seconds and is capable of calling discomfort with dynamic movement and acceleration.

  2. The absence of the possibility of adapting under the driver's motion manner. When the machine is able to adjust, then the "robot" can support only one manner, which is installed in the control unit as a firmware.

  3. When using a hydraulic drive, a brake fluid under pressure is used, which speeds up the switching procedure by 0.05 seconds. However, the hydraulic drive is much more expensive in the device and increases the energy engine capacity, being a lot of sports cars and prestigious cars.

  4. Excellent pickup trucks, in which the motorist can choose a driving manner (speed increase of motor revolutions).
  5. The ability to apply all the power of the motor and torque (high efficiency of the efficiency).
  6. High acceleration dynamics and fuel economy in comparison with automatic transmission.

Advice of professionals, mechanics or automatic, which is better

4C8B208S-96000000000000000000000000000000000000073868383706341081680136806408618684614112.

It is impossible to say with confidence which gearbox is better - automatic transmission or manual transmission, because both the first and the second box has its advantages and disadvantages. For example, some experienced drivers do not recognize automatic transmission at all, while others do not even imagine how to drive a car on a manual box. The automatic transmission is more convenient for use, and the MCPP is simple and inexpensive in maintenance and repair.
