Abstract

The invention discloses a flexible flywheel, and relates to the technical field of automobile components. The flexible flywheel comprises a connecting flange, a signal panel, starting teeth and a compressing disk; the compressing disk is connected with the middle of the one side of the signal panel in a pressing manner; the starting teeth are fixed on the other side of the signal panel; the other side of the signal panel opposite to the compressing disk is fixedly connected with the connecting flange; a forward reinforcing rib and a reverse reinforcing rib are arranged on the signal panel; the forward reinforcing rib is bulged towards the compressing disk; material removal holes are distributed at the periphery of the reverse reinforcing rib; 58 signal teeth are distributed on the signal panel; the width of each signal tooth is 5.1mm; and the signal panel and the connecting flange are provided with location holes. With the adoption of the flexible flywheel, switchover between a crankshaft and a hydraulic torque converter in a vehicle can be realized, and the starting performance and the NVH (Noise Vibration and Harshness) comfort of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a flexible flywheel used for connecting a crankshaft and a hydraulic torque converter on an automatic transmission vehicle. Background technique [0002] The automatic transmission model that connects the hydraulic torque converter and the crankshaft through a flexible flywheel has outstanding performance in terms of starting performance and NVH comfort. Due to the low-speed torque-increasing characteristics of the hydraulic torque converter, the vehicle starts and low-speed driving performance is superior, especially in models with turbocharged engines; the deformable characteristics of the flexible flywheel make the engine torque can be smoothly transmitted to the hydraulic converter. The torque converter reduces the torsional vibration transmission of the transmission system and greatly improves the NVH comfort. Contents of the invention [0003] The techni...
