What is the role of the steering cross shaft?
The role of the steering cross shaft is to achieve the transmission of variable Angle power, which is used for the position that needs to change the direction of the transmission axis, and it is the "joint" part of the universal transmission device of the automobile drive system.
The cross shaft of the direction machine will be broken, the steering wheel will be difficult to return to the position, the steering wheel will shake or run off, the steering wheel will be heavy, the direction machine will be light, the direction machine will leak oil, the direction machine will sound abnormal and other symptoms. The cross shaft is the universal joint, commonly known as ten bytes, the cross shaft is the joint component of the universal transmission device of the automobile drive system, and is one of the key parts of the rigid universal joint of the cross shaft.
The steering machine, also known as the steering device, is the most important part of the car for the steering function. At present, the steering system configured on the automobile can be roughly divided into mechanical steering, mechanical hydraulic power steering, electronic hydraulic power steering system and electric power steering system. Most of the current models are equipped with electronic hydraulic or electric power assist systems, and the mechanical steering gear has been gradually eliminated.
The role of the steering gear is to transform the steering torque and steering Angle from the steering disc appropriately (mainly deceleration and torque increase), and then output to the steering rod mechanism, so that the car steering, so the steering gear is essentially a deceleration transmission device. There are many types of steering gear, such as rack and pinion type, circulating ball type, worm crank finger pin type, power steering gear and so on.
There are two kinds of power steering gear: pneumatic and hydraulic. The hydraulic power steering gear can be divided into three structural types: integral, semi-integral and separated according to the arrangement and connection relationship of the mechanical steering gear, steering power cylinder and steering control valve in the steering gear.
Turn to ten bytes for bad performance
The performance of steering ten bytes broken mainly includes steering wheel return difficulty, steering wheel shake or deviation, steering wheel heavy, direction machine oil leakage, direction machine abnormal sound.
Steering wheel return difficulty: When the car has a difficult steering wheel return phenomenon during the driving process, this may be because the steering system of the car is faulty, possibly the steering ten bytes are damaged.
Steering wheel shake or deviation: If the ten bytes of the direction machine are damaged, the steering wheel shake or deviation may occur in the car.
Heavy steering wheel: ten bytes damaged, the direction machine can not turn, the car will be very heavy to hit the steering wheel.
Direction machine oil leakage: After the car direction machine is damaged by ten bytes, the lubricating oil may leak out from the damage, and the direction machine oil leakage will occur.
Direction machine abnormal sound: When the car turns or turns around, the steering wheel is full of abnormal sound, which is the performance of ten bytes of damage to the direction machine.
These symptoms are obvious signs of steering ten-byte damage, and once these symptoms are found, the steering machine ten-byte should be repaired or replaced in time to avoid further damage and safety hazards.
Cross universal joint removal method
The method of removing the cross universal joint is:
1. Lift the front end of the vehicle with a jack. Place the jack at the front of the frame for stability. Drain transmission fluid to prevent leakage. Fill the transmission plug;
2. Prepare a container for the fluid and disconnect the drain plug of the transmission. Ensure the integrity of the drive shaft assembly by creating reference marks. Remove the mounting clamp or bolt to drive the drive shaft;
3. Remove the drive shaft from the transmission by removing the shackles. Secure the bearing cover with tape for the needle roller bearing to prevent collision. Stabilized in the auxiliary drive shaft. The tape was deleted. Remove the bearing from the yoke through the dismounting ring;
4, use different sizes of sockets and vise provided by the lever to keep the bearing cover away from the yoke. Use the pliers to push the lid onto the assembly. Turn the drive shaft around the vice and repeat the previous process at the other end;
5, will be from the two yoke and drive shaft of the universal joint. Remove all dirt and debris from the entire drive shaft assembly to ensure it is completely clean. Apply a small amount of grease to the replacement cover. Insert the bearing cover part into the yoke and replace the bearing cover;
6. Install the universal joint into the cover. Partially insert opposing caps. Line up the universals and push the cover into place with a press. Insert the buckle. Position the drive shaft. Make sure the yoke is properly aligned with the drive shaft.
