Low-floor vehicle body free hinge triangular hinged support and connection mode thereof

Abstract

The invention provides a low-floor vehicle body free hinge triangular hinged support and a connection mode thereof. A triangular-structure installation seat comprises a contact surface connected with a vehicle body, a hinged bulb installation seat connected with a free hinge pull rod, and an oblique supporting edge. The two ends of the contact surface connected with the vehicle body and the hinged bulb installation seat form a triangle, the contact surface connected with the vehicle body is located on the edge of the inner side of the vehicle body, another edge of the triangle is an arc-shaped edge connected with a hinge point which is connected with the contact surface and the triangular support, the arc-shaped edge is located on the outermost edge of the whole support, and the third edge of the triangle is the oblique supporting edge which is located on the inner side of the vehicle body. Through the arc-shaped edge and the oblique supporting edge, the hinge point connected with the free hinge pull rod and the triangular support is located outside the outer side of the portion, corresponding to the triangular support and the vehicle body contact surface, of the vehicle body on the horizontal plane. When a free hinge is subjected to tensile force of the free hinge pull rod during operation, the triangular support and the vehicle body contact surface are integrally in a pressed state, and the stress of the support and the vehicle body contact surface is reduced.

Description

technical field [0001] The invention relates to a vehicle connecting component device and its connection method, in particular to a free hinge support for a hinged connection system between a low-floor vehicle body and a vehicle body and its connection method, which are used to improve the free hinge connection The stability and reliability of the free hinge are reduced, and the free hinge support structure is optimized. The invention belongs to the technical field of vehicle key component manufacturing. Background technique: [0002] At present, low-floor vehicles mostly use hinged devices to connect the car bodies. The hinged devices are arranged at the connecting parts of the two ends of the car body. Generally, the upper and lower hinges are used to restrict the movement of the car body through each hinged device, so that the low-floor vehicle has a good performance. The ability of too small radius curve. The bottom of adjacent cars of low-floor trains generally adopts...

Problems solved by technology

[0010] The purpose of the present invention is to propose a new installation and connection method of the free hinge hinge support and the hinge joint support for the existing low-floor vehicle hinge system. Support, the installation and connection method of the free hinge hinge support and the hinge support improve the performance of the low floor vehicle free hinge hinge by changing the installation connection method and structure of the free hinge hinge system of the low floor vehicle hinge system, and improve the force of the free hinge hinge system situation, and reduce the weight of the free hinge mounting seat, making the structure of the free hinge mounting seat simpler and more reasonable. Under the lighter structure, the service life of the free hinge is improved, and the structure is simple and easy to repair and replace.
