What is the structural principle of the Howola clutch?

The clutch is installed between the engine and the transmission, and is the assembly that is directly connected to the engine in the drive train of the car. Usually the clutch is installed together with the flywheel group of the engine crankshaft, which is the component that cuts off and transmits power between the engine and the drive train of the car. During the entire process from the start of the car to normal driving, the driver can manipulate the clutch as needed to temporarily separate or gradually engage the engine and the drive train to cut off or transfer the power output from the engine to the drive train.

Its function is to make the engine and transmission gradually engaged, so as to ensure a smooth start of the car; Temporarily cut off the connection between the engine and the transmission in order to facilitate gear shifting and reduce shock when shifting; When the car is braking in an emergency, it can play a detaching role to prevent the transmission and other transmission systems from being overloaded, so as to play a certain protective role.

The clutch is similar to a switch, engagement or disconnection of power transmission, the active part of the clutch mechanism and the driven part can be temporarily separated, and can be gradually engaged, and it is possible to rotate relative to each other during the transmission process. There can be no rigid connection between the active part of the clutch and the driven part. Any form of car has a clutch, it's just in a different form.

1] Classification. According to the analysis of the "Prospect of the Analysis Report on Production and Marketing Demand and Investment in China's Clutch Manufacturing Industry", clutches are divided into four types: electromagnetic clutches, magnetic powder clutches, friction clutches and hydraulic clutches

Electromagnetic clutch.

The engagement and disengagement of the clutch are controlled by the on/off power of the coil.

Electromagnetic clutches can be divided into: dry single-plate electromagnetic clutch, dry multi-plate electromagnetic clutch, wet multi-plate electromagnetic clutch, magnetic particle clutch, differential electromagnetic clutch, etc.

The working mode of electromagnetic clutch can be divided into: energized combination and power-off combination.

When the clutch is pressed, the transmission of the engine is disconnected from the wheels, and the power of the engine is not transmitted to the wheels to drive the car; When the clutch is released, the transmission of the engine is connected to the wheels, and the power is transmitted to the wheels, and the car has power. The clutch mainly plays the role of separation between the engine and the wheel transmission.

The electromagnetic clutch is a set of coils, and when it is supplied with power, it will be sucked and sucked, so that the compressor pulley is not idling.

Answer: An electromagnetic clutch is a friction clutch that generates a compressive force from an electromagnetic force. Because it can realize long-distance operation, the control energy is small, it is convenient to realize the automation of machine tools, and at the same time, the action is fast, the structure is simple, and it has also been widely used.

Electromagnetic clutch is also known as electromagnetic coupling. It is an electromagnetic mechanical connector that applies the principle of electromagnetic induction and the friction force between the internal and external friction plates to make the two rotating parts in the mechanical transmission system, and the driven parts can be combined or separated from it under the condition that the active parts do not stop rotating, and it is an automatic electrical appliance. Electromagnetic clutches can be used to control the starting, reversing, speed regulation and braking of machinery.

It has simple structure, fast action, small control energy, and easy long-distance control; Although the volume is small, it can transmit large torque; When used as a brake control, it has the advantage of fast and smooth braking, so electromagnetic clutches are widely used in various processing machine tools and mechanical transmission systems.

The role of the electromagnetic clutch is to transfer the torque (or power) of the actuator from the side of the driving shaft to the side of the driven shaft. It is widely used in various mechanisms (such as transmission mechanisms and various electric mechanisms in machine tools, etc.) to achieve functions such as fast start, braking, forward and reverse rotation or melancholy speed. Electromagnetic clutches are an important component in automatic control systems because they are easy to control from a distance and are much easier to operate than other mechanical, hydraulic or pneumatic clutches.

Electromagnetic clutches are an important component in automatic control systems because they are easy to control from a distance and are much easier to operate than other mechanical, hydraulic or pneumatic clutches.

The working principle of the electromagnetic clutch is an electromagnetic mechanism that uses electromagnetic attraction to form surface friction or mesh, and uses electromagnetic induction to isolate or transmit torque between the driving shaft and the driven shaft. Ordinary clutches need to be pushed by manpower, while electromagnetic clutches are pushed by electromagnetic suction.

Electromagnetic clutches rely on coil energizing and power-off to control engagement and separation. When the coil is energized, the magnetic force is generated to attract the "armature" plate, and the clutch is in a state of engagement, and the "armature" springs back after the coil is powered off, and it is in a state of separation.

After the brake is pressed, the master cylinder generates thrust to push the hydraulic oil against the cylinder, and the piston inside the cylinder begins to move under hydraulic force to push the brake pads.

Clutch master cylinder, sub-cylinder, equivalent to two hydraulic cylinders. There are inlet and outlet pipes on the main pump and only one pipe on the sub-pump. When the clutch is pressed, the pressure of the master cylinder is transmitted to the sub-cylinder, and the sub-pump works, and the disconnect fork disengages the clutch pressure plate and plates from the flywheel, and then you can start shifting.

Release the clutch, the sub-cylinder stops working, the clutch pressure plate and the plate are in contact with the flywheel, the power transmission continues, and the oil of the sub-cylinder flows back into the oil can. When the shift is difficult and the separation is not complete, it is necessary to detect the clutch master cylinder, whether there is oil leakage in the sub-pump, and solve the problem in time to reduce wear. Others should be tested accordingly.

The sub-cylinder is a hydraulically controlled gas-assisted The brake fluid pushes the piston of the sub-cylinder after the master cylinder is pressed, and then the air and liquid push the piston together to disengage the clutch.

Before 09 years, 336 horsepower Howo used ordinary 420, after 09 years, there was a pull clutch B type Pull driven disc is much higher than the middle disc hub of ordinary driven disc Pull driven disc ** high but better quality!

Before '09, the 336 horsepower Howo used a regular 420, and after '09 there was a pull clutch type B.

The middle hub of the pull driven disc is much higher than that of the ordinary driven disc.

The pull driven disc is high but the quality is better!
