Four-axis single-hinge hinge type passenger car structure

Abstract

The invention discloses a four-axis single-hinge hinge type passenger car structure and relates to the technical field of passenger car structures. The four-axis single-hinge hinge type passenger car structure is composed of a main car (1) and an auxiliary car (2), wherein the length of the auxiliary car is equal to or slightly smaller than that of the main car. The main car (1) and the auxiliary car (2) are both of double-axle structures, a front axle (3) of the main car is a steering axle, a rear axle (4) of the main car is a driving axle, a front axle (5) of the auxiliary car is a follow-up axle, a rear axle (6) of the auxiliary car is a linkage steering axle, and the main car is connected with the auxiliary car through a traction capstan (8) and a soft shed (9). A deflection angle alpha of a middle point of a wheel shaft of the linkage steering axle of the auxiliary car is in linkage connection with a relative swinging angle beta between the main car and the auxiliary car. The four-axis single-hinge hinge type passenger car structure can ensure the moving tracks of the main car and the auxiliary car to be basically the same, enables drivers to drive easily, simultaneously reduces the width of a steering channel and saves road resources. Additionally, a main car and auxiliary car connection capstan does not bear vertical load, so that working load of the capstan is greatly reduced, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to the field of passenger car structure design, and invents a novel articulated passenger car structure form. technical background [0002] At present, most of the articulated buses operating in China are three-axle articulated buses with rear-mounted engines to achieve front-wheel steering. When traditional articulated buses are used in the BRT system, the turning channel width required is relatively large and takes up more roads. space. For the passenger car structure with the rear engine, it is necessary to use high-cost push-type articulated discs. A new type of four-axle single-hinge articulated bus is proposed according to the traffic situation in our country. Contents of the invention [0003] The present invention provides a four-axle single-hinge articulated bus with small turning channel width, easy driving and low cost. [0004] In conjunction with the accompanying drawings, the description is as follows: [0005]...
