Novices who drive semi-trailers are not familiar with cars and are not very skilled in operation, so it is estimated that they will encounter many problems. The following is a discussion on how to hang the semi-trailer gear for novices.

Today's semi-trailers generally have two partner gears, 8 gears and 12 gears (Fast gearbox). Steyr Howo 336 is an 8-speed box, plus half and reverse gears are ten gears, which is the so-called 9 forward gears and one reverse gear. The specific hanging method is also very simple, and it can be seen at a glance on the gear lever. In the low-speed position, pull it to the left and pull it back to the first gear, and push it to the left to push it forward to the second gear. Under the action, it will automatically stop in the neutral position of the third and fourth gears), and the direct pull back is the third gear.

Pushing it forward is the fourth gear. After returning to the neutral gear, go to the high-speed neutral position (you can hear the sound of the valve shifting the gear on the gearbox). 4th and 5th gear neutral position), pull back directly is fifth gear, push forward directly is sixth gear, move to the right after neutral, pull back is seventh gear; push forward is eighth gear.

On the basis of the neutral position of the first and second gears in the low-speed gear, lean to the left forcefully. Pull back is reverse gear (R), and push forward is half gear (C). The Auman 9 series uses the Fast 12-speed gearbox, which is simpler to hang (plus R1 and R2 for a total of 14 speeds), which is the same as the old seven-speed gearbox. Push the first gear forward lightly to the right, and pull the second gear slightly backward to the right. In the middle of the neutral position: push forward is the third gear, pull back is the fourth gear, push the left lightly forward for the fifth gear, pull the left lightly backward for the sixth gear, and pull up the gear high-low switching valve (look under the ball head of the gear lever). can be seen).

Repeat the previous action for 7th to 12th gears, leaning hard to the right in neutral position: push forward to reverse gear (R1 in low gear, R2 in high gear). R2 is generally only used when the car is empty, and the speed can reach 40 kilometers per hour.

Empty vehicles can start below 7th gear, and heavy vehicles can start below 3rd gear. Second, it depends on the main car of your semi-trailer. If it has 7 forward gears, it will be the same as a normal bicycle. If the front of the car has 9 forward gears, even if you draw a gear map for you, you will not understand it. Cars with 9 forward gears generally have two gearboxes. When searching for a horizontal gear, air pressure assists to convert the gearbox. It depends on the feel. The common gear is to push forward, and 1357 down is half 2468. 13 and half 24 is a gearbox 5678 is a gearbox.

When you use the reverse 1234 gear, the driving method is the same as the normal car. When you want to hang the 4678 gear, move the gear lever to the right when you are in neutral. When you move to the far right, move it hard to the right. You can hear the sound of exhaling and reverse the other gearbox.
