A tractor truck is a generally large truck or semi-trailer that is pulled between the front and the trunk by tools. That is to say, the front of the car can break away from the original carriage and tow other carriages. And railway carriages also can break away from their former headstock and be pulled by other headstocks. The front of the vehicle with driving capability is called a tractor truck, and the vehicle without traction and driving capability at the back is called a trailer, and the trailer is towed by the 6x4 tractor truck. Next, let's take a look at the function and maintenance of the tractor truck.
Here is the content list:
l The role of the tractor truck.
l Overhaul of tractor truck.
1. Anti-skid: The tractor truck can prevent the driving wheels from idling when driving on wet and slippery roads such as snow so that the vehicle can start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system of the CNG tractor truck can ensure smooth acceleration performance and prevent the vehicle from laterally moving or drifting due to slipping of the driving wheels.
2. Flexible: the tractor truck makes the car and train have better maneuverability when pulling the car.
3. Reliable work: the tractor truck ensures reliable, convenient, and rapid detachment of the connection between the towing vehicle and the trailer.
4. Stability: The traction force can be smoothly transmitted to the trailer, which has a certain buffering effect on the impact load.
Overhaul of tractor truck.
1. During the first-level maintenance, it is necessary to check the components of the fifth wheel of the tractor truck. In particular, check the wear of the traction pin, traction pin plate, half horizontal shaft, and other parts, and lubricate these parts. Tighten the support bolts and replace the bolts if necessary. Adjust the matching gap between the lock hook and the traction pin. The adjustment method is to adjust through the adjustment screw and lock it through the nut after adjustment.
2. When disassembling the fifth wheel for inspection, pay attention to check whether there are cracks and serious wear on the fifth wheel itself. If there are cracks or severe wear and the fifth wheel is deformed or too thin, replace it with a new one. Check the lock hole, and use the traction pin for matching detection. If the wear exceeds the limit and the fit gap is large, it can be repaired by surfacing welding and machining to the required size. Shackles, lock blocks, and worn rings can also be replaced for repair. Check the fit clearance between the support and the body, if the fit is loose, replace the rubber elastic bushing. Check the locking mechanism, the detachment and connection should be smooth and crisp, and the safety device should be firm and reliable. If there is any abnormality, check the tension spring of the lock hook and the tension spring of the numbering handle. Check the insurance mechanism, if the spring elasticity is weakened, replace it with a new one.
In addition to completing the same items as those of the single-axle fifth wheel, the inspection and maintenance of the double-axle fifth wheel of the 4x2 tractor truck should also pay attention to the following points:
1. Check the monolithic horizontal and vertical axes. If there is deformation and serious wear, it should be welded to the required size, repaired, or replaced with a new one. Ensure that the fifth wheel can flexibly swing horizontally and vertically, and the matching clearance should meet the standard.
2. Check the transverse swivel angle and the cushioning on both sides. If the lateral swing angle is too large, adjust it through the wedge-shaped blocks on both sides. If the buffer spring or rubber block is aging, replace it with a new one.
