Guiding type car coupler with buffering device

Abstract

The invention provides a guide type car coupler with a buffer device. The guide type car coupler is provided with a rear baffle fixedly connected with a car frame through a rear baffle connecting piece. The rear baffle and the front baffle are arranged in parallel in a front-and-back spaced mode, and a rubber spring which horizontally stretches out and draws back is coaxially and fixedly connected between the rear baffle and the front baffle. The front side of the front baffle is fixedly connected with a cam; the front side of the collision iron is fixedly connected with a collision end plate; the collision end plate, the collision iron and the front baffle synchronously and axially stretch and displace along with the front side end of the rubber spring; a linear guide assembly is arranged between the rear baffle and the cam; the linear guide assembly is used for providing linear guide for synchronous axial telescopic displacement of the collision end plate, the collision iron and the front baffle along with the front side end of the rubber spring. The rubber spring with the linear guide assembly is used for buffering longitudinal impact and vibration in the train running process, and the destructive effect is relieved; the guide type car coupler is simple in structure, convenient to manufacture, stable in operation, excellent in vibration absorbing and buffering capacity, economical, practical and safe.

Description

technical field [0001] The invention belongs to the technical field of railway vehicle traction connection buffers, and in particular relates to a guide type coupler with a buffer device. Background technique [0002] The coupler buffer device is an important part of the train, which is used to realize the connection between the locomotive and the vehicle or between the vehicle and the vehicle, and plays the role of transmitting traction and impact to realize the connection between the two trains. [0003] Under the existing technology, due to the limited cushioning effect of the coupler, the longitudinal impact and vibration caused by the collision of the vehicles due to the change of the traction force of the locomotive during the coupling and running of the train or during starting, braking and shunting operations cannot be achieved. Effective absorption will easily cause damage to the car body and loads; at the same time, it will lead to poor running stability of the tra...
