Multi-joint marshaling vehicle

Abstract

The invention discloses a multi-joint marshaling vehicle which comprises at least three compartments. Two adjacent compartments are hinged, two compartments located at the two ends are each provided with at least two wheel axles, the compartments located at the middle are each provided with at least one wheel axle, all the wheel axles are all connected with an assistance steering device for driving the wheel axles to steer, and the assistance steering device is connected with a steering control unit so that the steering control unit can control all the wheel axles to actively steer through theassistance steering device. When the vehicle runs, when a bend is met, a control instruction can be sent to the assistance steering device through the steering control unit so that the assistance steering device can drive the wheel axles to perform steer motions, active steering of the wheel axles can be achieved, and therefore the multi-joint marshaling vehicle steers stably and reliably, and the vehicle bend traffic ability and comfort level are improved.

Description

technical field [0001] The invention relates to the technical field of bus vehicles, and more specifically, relates to a multi-section marshalling vehicle. Background technique [0002] For second- and third-tier cities that cannot build subways due to input cost constraints, super-long buses with large and medium-capacity will undoubtedly become one of the best solutions to relieve urban traffic pressure. [0003] However, most of the bus vehicles in the prior art are ordinary buses composed of one section or BRT express buses composed of two sections. The vehicle length of marshalling vehicles is long, and there are many curves or roundabouts in the city. Therefore, when passing through curves, the following performance of each wheel is poor, resulting in poor passability of vehicles. Moreover, during the operation of the vehicle, especially at medium and high speeds, there will be a horizontal serpentine running form between a single carriage and different carriages, res...

Problems solved by technology

[0003] However, most of the bus vehicles in the prior art are ordinary buses composed of one section or BRT express buses composed of two sections. The length of the marshalling vehicle is long, and there are many curves or roundabouts in the city. Therefore, when passing through the curve, the following performance of each wheel is poor, resulting in poor passability of the vehicle.

Moreover, during the operation of the vehicle, especially at medium and high speeds, there will be a horizontal serpentine running form between a single carriage and different carriages, resulting in poor comfort and stability of the vehicle, and even in a small Under the steering action, the entire train of vehicles may have an accident of tail flicking and rollover

[0004] Therefore, limited by the steering control system of the existing bus vehicles, there is currently no relevant technical reserve for super-long buses with more than three sections, and there are no relevant design and test standards for ultra-long buses with multiple sections in the automobile and rail transit industries. Therefore, many Sectional marshalling vehicles belong to the technical blank area of ​​the automobile and rail transit industry
