The invention provides a hinge spring type vehicle anti-creeping energy absorption device. The device is mainly composed of a front end anti-creeping structure, a rear end installation structure and amiddle hinge type spring energy absorption structure. The middle hinge type spring energy absorption structure is composed of an inner connecting rod, an outer connecting rod, a pin column and a spiral spring, and comprises five hinge type spring energy absorption basic units from top to bottom, and the torsional rigidity of the spiral spring is sequentially increased. When a vehicle collides ata low speed, the spiral spring generates recoverable elastic torsion to store energy, and the anti-creeping energy absorption device is not damaged; when a vehicle collides at a high speed, the spiralspring generates unrecoverable plastic deformation to absorb energy; and the rigidity of the spiral spring controls the deformation sequence of the energy absorption structure, and the five hinge type spring energy absorption basic units deform in sequence from top to bottom. According to the invention, the technical problems of serious waste, high maintenance cost and unstable energy absorptionsequence of the traditional energy absorption structure for low-speed collision of the railway vehicle can be effectively solved, and the collision resistance of the railway vehicle can be effectivelyimproved.
本发明提供一种铰接弹簧式车辆防爬吸能装置,主要由前端防爬结构、后端安装结构以及中间铰接式弹簧吸能结构组成;中间铰接式弹簧吸能结构由内连杆、外连杆、销柱及螺旋弹簧组成,由上至下包括5个铰接式弹簧吸能基本单元且螺旋弹簧扭转刚度依次增大。车辆低速碰撞时,螺旋弹簧产生可恢复弹性扭转储存能量,防爬吸能装置不发生损坏;车辆高速碰撞时,螺旋弹簧发生不可恢复塑性变形吸收能量;螺旋弹簧刚度控制吸能结构变形次序,从上到下,5个铰接式弹簧吸能基本单元依次变形。通过本发明可以有效得解决轨道车辆低速碰撞传统吸能结构浪费严重、高维修成本以及吸能次序不稳定的技术问题,可以有效提高轨道车辆的耐撞性。
