Steering drive module and corresponding vehicle

Abstract

The invention discloses a steering drive module and a corresponding vehicle, and relates to the technical field of trolleybuses. The steering drive module is provided with four wheel bodies, a motor provides driving force for the wheel bodies in a centralized or decentralized mode, a steering controller utilizes a hydraulic actuator to execute a steering instruction, driving and steering are integrated, and thus the vehicle achieves flexible steering of the wheel bodies when meeting the bearing requirement. The invention further discloses a trolleybus provided with the steering drive module, and the trolleybus determines the wheel path and achieves the function of tracking by recognizing ground marks or the direction of front steering wheels.

Description

technical field [0001] The present invention relates to the technical field of trackless buses, in particular to a steering drive module, which is used to realize the integrated control of steering and driving, and also relates to a track train, which adopts the steering drive module to carry out integrated control of driving and steering. , and can also realize the functions of tracking and printing. Background technique [0002] In order to alleviate the problem of urban traffic congestion, trackless buses have gradually entered the public's field of vision. With the continuous development of technology, trackless buses have begun to change from gas to electric to improve environmental performance. [0003] The performance parameters of the current trackless bus are not good. For example, some manufacturers use a single-tire bus, and each tire can realize the steering function independently, but the carrying capacity is insufficient, especially when the body size of the bu...

Problems solved by technology

[0003] The performance parameters of the current trackless bus are not good. For example, some manufacturers use a single-tire bus. Each tire can realize the steering function independently, but the carrying capacity is insufficient, especially when the body size of the bus is long. The carrying capacity is limited, the load-bearing capacity of the axles and tires can only meet the weight of the car body, and it is impossible to free up too much weight to meet the passenger demand, resulting in the failure to meet the vehicle configuration requirements; although some manufacturers adopt twin tires (left and right arrangement structure) The passenger car with two single tires) solves the load-carrying problem, but the wheels of its twin tires do not have the steering function, resulting in the lack of flexibility of the car body during the steering process, which is not suitable for low-floor buses. The inner tires will have strong friction with the ground, and the degree of wear and tear will be greater. The passenger car with twin tires will also narrow the aisle of the car body, and the size of the car body is not good, which will affect the passenger capacity.
