Small trucks have a drive mechanism similar to most other cars with either an automatic drive or a manual drive system with synchronous equipment. Larger trucks are more likely to use manual transmission without synchronous gear, and are lighter in weight, although some synchronous transmission has been adopted in heavy trucks. Asynchronous drive that requires two maneuvers per gear shift can cause damage from repetitive motion. Common North American standards include 10, 13, and 18-speed semi-automatic and semi-automatic transmissions for heavy trucks, and these standards are increasingly popular, for their advantages both in transmission. and engine power.
The trend in Europe is that more and more new trucks are using automatic transmissions. This is partly due to the lawsuits filed by drivers claiming that manual transmission is harmful to their knees.
