Example Embodiment

[0025] see figure 1 , figure 2 , On the base 16 of the test bench, the left flywheel 6 and the right flywheel 4 are connected by the elastic coupling 5 to form a unitized synchronously rotating double inertia flywheel group. The left drive belt 8 and the left driven pulley 9, and the right drive belt 15 and the right driven pulley 13 constitute a power transmission mechanism between the left and right shaft ends of the flywheel set respectively. The double inertia flywheel set is provided by the frequency conversion motor 1. Power source; The transmission AMT is fixedly arranged on the transmission fixture plate 12 of the corresponding model, and the left half shaft 10 and the right half shaft 11 of the transmission are used to simulate the input shaft and output shaft during the shifting process of the transmission.

[0026] like figure 1 As shown, the power transmission mechanism composed of the left drive belt 8 and the left driven pulley 9, as well as the right drive be...

Abstract

The invention discloses a test bed of AMT shifting durability and is characterized in that a left flywheel and a right flywheel are connected into a double-inertia flywheel group with united and synchronous rotation by an elastic shaft joint, a left transmission belt and a left driven belt wheel between a left half shaft and a right half shaft of a gear box as well as a right transmission belt and a right driven belt wheel between the ends of a left shaft and a right shaft of the double-inertia flywheel group respectively form a power transmission mechanism, and the power source of the double-inertia flywheel group is provided by an electric variable-frequency motor. The test bed of AMT shifting durability not only can satisfy functional requirements and truly simulate the AMT shifting process of a whole car, but also has simple mechanical structure, easy assembly and disassembly, easy adjustment, low production and maintenance cost, safety and reliability, and can satisfy the longtime frequent testing requirement of the gear box.

Description

technical field [0001] The invention relates to an automobile test device, more specifically to a test bench mechanical structure for realizing the durability performance test of an AMT (Automated Mechanical Transmission, electronically controlled mechanical automatic transmission) synchronizer. Background technique [0002] Automobile mechanical automatic transmission AMT is an electronically controlled mechanical transmission. It is based on the MT mechanical transmission, canceling the shift handle and clutch pedal, and adding the ASCS automatic shift control system. ASCS is composed of actuators controlled by microcontrollers, and uses electronically controlled hydraulic (pneumatic) or motor mechanisms instead of manpower to control clutch and gear selection mechanisms, so as to realize the automatic transmission function of automobiles. Because of its automatic shift function, AMT can greatly improve the service life of clutches and synchronizers and driving safety, and...
