Passenger car hinge joint shed

Abstract

The invention discloses a passenger car hinge joint shed which comprises a portal frame, a shed body and an equiangular mechanism, wherein the shed body is connected with the portal frame and provided with a ceiling and an outer shed, and the equiangular mechanism is arranged in the space formed by the ceiling and the outer shed and comprises a slide beam, a tackle, a pull rod and a fixing seat. The tackle slides along the slide beam, two ends of the pull rod are connected on the tackle and the fixing seat respectively, the fixing seat is fixedly connected on a front compartment and a rear compartment of a passenger car, the tackle comprises a support, a mounting plate and pulleys, the mounting plate is fixedly connected on the support, the pulleys are connected on the support, the pull rod is connected on the mounting plate of the tackle, the mounting plate is made of polyurethane materials, and flexible connection capable of buffering torsion is formed between the pull rod and the tackle through the mounting plate. The equiangular mechanism can buffer impact force generated in turning of the passenger car and torsion generated in bumping of the passenger car by the aid of flexible connection, and the service life of the equiangular mechanism can be prolonged.

Description

technical field [0001] The invention relates to the technical field of large passenger cars, in particular to a passenger car hinged shed for connecting front and rear compartments of a large passenger car. Background technique [0002] In the prior art, the transition between the front and rear compartments of a large articulated bus is connected by a hinged shed. Since the shed body of the hinged shed is generally made of soft fabrics such as rubber or artificial leather, the hinged shed also has There are connection mechanisms such as gantry frame and equiangular mechanism to strengthen the strength of the transition part and the reliability of the connection. [0003] However, because the vehicle will form a certain torsion force on the transition part due to the bumping or turning of the vehicle during driving, the connecting mechanism on the transition part in the prior art, such as the equiangular mechanism, is all rigidly connected, such as the pull rod and the pulle...

Problems solved by technology

[0003] However, because the vehicle will form a certain torsion force on the transition part due to the bumping or turning of the vehicle during driving, the connecting mechanism on the transition part in the prior art, such as the equiangular mechanism, is all rigidly connected, such as the pull rod and the pulley in the equiangular mechanism The connection between the pull rod and the fixed seat, etc., the rigidly connected pull rod and the pulley, the fixed seat and other components will inevitably cause fatigue, severe wear and even damage to these parts under long-term torsion, which will affect the service life of the equiangular mechanism.

At the same time, the pulley, the fixed seat and the corner shed frame of the gantry frame in the conventional medium-angle mechanism are all formed by iron materials, which are easy to rust, heavy in weight, and difficult to manufacture.
