Dual-mass flywheel and vehicle

In order to solve the problems that a spring in an existing dual-mass flywheel is large in friction damping and prone to abrasion and fracture, the dual-mass flywheel comprises a main flywheel assembly, a secondary flywheel assembly, a self-lubricating spacer and the spring, a cavity is formed between the main flywheel assembly and the secondary flywheel assembly, and the self-lubricating spacer is arranged in the cavity. The self-lubricating spacer and the spring are located in the cavity, the self-lubricating spacer comprises main body resin and a fiber reinforced material arranged in the main body resin, and the main body resin comprises polyether-ether-ketone and polytetrafluoroethylene. Meanwhile, the invention further discloses a vehicle comprising the dual-mass flywheel. The dual-mass flywheel provided by the invention has good self-lubricating property, greatly reduces friction loss, improves torque transmission efficiency, does not need to add lubricating grease, reduces the cost, also reduces the re
