Abstract

The invention discloses a bus buffer, which comprises a concave ball pad, a convex ball pad, a pressing rod, a sleeve, a guiding rod, a first spring and a pre-tightening device. The concave ball pad is provided with a concave spherical surface; the convex ball pad is provided with a convex spherical surface matched with the concave spherical surface; the convex ball pad is fixed to the front end of the pressing rod; the sleeve limits a sleeve cavity, a front baffle is arranged at the front end of the sleeve cavity and provided with a first through hole, and a rear baffle is arranged at the rear end of the sleeve cavity and provided with a second through hole; the rear end of the pressing rod stretches into the sleeve cavity through the first through hole, and the pressing rod can slide inthe front-rear direction; the guiding rod slidably penetrates through the second through hole in the front-rear direction, the front end of the guiding rod stretches into the sleeve cavity, and the rear end of the guiding rod is located outside the sleeve cavity; the first spring is located in the sleeve cavity and mounted on the guiding rod, the front end of the first spring is fixed to the guiding rod, thus the rear end of the pressing rod makes contact with the front end of the guiding rod, and the rear end of the first spring is jacked on the front side face of the rear baffle; and the pre-tightening device is connected with the guiding rod to enable the first spring to generate pre-tightening force. According to the bus buffer, multi-directional impact loads of track buses can be buffered and subjected to shock absorption.

Description

technical field [0001] The invention relates to the technical field of rail passenger car buffering, in particular to a passenger car buffer. Background technique [0002] Rail passenger cars such as old cableways and cable cars are in the station building. Waste car tires or simple rubber products are generally installed in the direction of passenger cars entering the station, which constitutes a simple protection device. When the passenger car rushes to the station unexpectedly, using tires or simple rubber products to resist the collision of the passenger car is too simple and irregular, and cannot absorb the large impact and collision of the passenger car, causing personal injury and property loss. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to provide a passenger car buffer, which can buffer and damp the multi-directional...
