Description

Technical Field

[0001] The utility model specifically relates to the technical field of gearboxes, in particular to a test device for simulating frequent slope starts on a test bench for an automobile gearbox. Background Art

[0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or divided manner. It is also called a gearbox. The transmission consists of a speed transmission mechanism and a control mechanism. Some cars also have a power output mechanism. Most transmission mechanisms use ordinary gear transmissions, and some use planetary gear transmissions. Ordinary gear transmission speed change mechanisms generally use sliding gears and synchronizers.

[0003] Traditional transmission simulation start-stop, especially in slope start experiments, usually uses increased friction on the output shaft for testing, which cannot detect slope start output in accordance with the actual situation, resulting in inaccurate monitoring data. For this reason, we provide a vehicle transmission bench simulation frequent slope start test device. By adjusting the angle of the angle adjustment frame, the angle of the transmission belt can be adjusted to simulate the slope of the tilt. Since the transmission will rotate at the same time as the angle adjustment frame, the wheel can also fit the transmission belt, and the detection is more accurate, which effectively compensates for the above problems.
