These vehicles integrate advanced technologies in vehicle power control and drive, resulting in advanced technical principles, new technologies, and new structures. The transmission, also known as a gearbox, is a mechanism used to change the speed and torque of the engine. It can change the output and input shaft ratios in fixed or step-by-step fashion. A transmission consists of a speed change mechanism and a control mechanism. Some vehicles also have a power take-off mechanism. Most transmission mechanisms use conventional gears, though some use planetary gears. Conventional gear transmissions typically utilize sliding gears and synchronizers.

As the hot air rises and moves away, when the spring dampers 214 expand and contract to generate heat to heat the surrounding air, the air is driven into the bottom through the air intake filter hole 100. In the box 1, after the spring damper 214 absorbs heat, it rises through the through hole 213 and is then discharged from the bottom box 1 through the air outlet 302, thereby forming a stable heat dissipation airflow, which is convenient for improving the heat dissipation effect of the spring damper 214, reducing the probability that the spring damper 214 will work at too high a temperature for a long time and affect the shock absorption effect, and improving the stability of the installation and fixation of the automobile transmission; wherein, when the guide support bar 202 slides, it drives the threaded rod 207 to slide on the polygonal transmission shaft 2081 through the polygonal hole 2085, so that the threaded rod 207 and the guide support bar 202 can slide synchronously, so that the second hand wheel 2082 can drive the sliding threaded rod 207 to rotate.
