Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] refer to figure 1 and figure 2 , a steering device for a wheel-steering semi-trailer in this embodiment includes several axles 1 arranged in parallel in the transverse direction, steering wheel components 2 and a drive system for driving the steering wheel components 2 to turn at both ends of the axles 1.

[0014] The driving system of the present embodiment includes a support base 9 and two steering drive cylinders 3 arranged in parallel. The support base 9 is T-shaped. The support base 9 includes a transverse fixed plate 9.1 and a longitudinal connecting rod 9.2. At both ends of the transverse fixing plate 9.1, one end of the longitudinal connecting rod 9.2 is fixedly arranged in the middle of the transverse fixing plate 9.1, and the other end of the longitudinal connecting rod 9.2 extends to the rear.

Abstract

The invention discloses a semitrailer steering device with steerable wheels. The semitrailer steering device comprises wheel axles, steerable wheel assemblies and a driving system, wherein a mounting base is arranged in the middle of each wheel axle; each mounting base comprises a mounting bottom plate through which a vertical pin shaft penetrates and a mounting top plate through which the vertical pin shaft penetrates; each vertical pin shaft is hinged to a steering base; each steering base comprises a transverse plate and a longitudinal plate, which are integrated into a whole; the middle of each transverse plate and the front part of the corresponding longitudinal plate are hinged to the corresponding vertical pin shaft; two ends of the transverse plate which is close to one side of the driving system are respectively hinged to output ends of steering driving oil cylinders; every two adjacent transverse plates are connected together through a longitudinal pull rod; the longitudinal pull rods are in staggered arrangement; two connecting parts are arranged at the rear edge of each longitudinal plate; each connecting part is connected with the corresponding steerable wheel assembly through a transverse pull rod and a steering arm. When the wheel axles deviate while the semitrailer runs, only the steering driving oil cylinders are controlled so as to align the foremost wheel axle, so that the wheel axles behind the foremost wheel axle can be aligned through the longitudinal pull rods; the semitrailer steering device is suitable for semitrailers which transport wind turbine tower cylinders and run on curved mountain roads.

Description

technical field [0001] The invention relates to the technical field of semi-trailer transmission, in particular to a wheel-steering semi-trailer steering device. Background technique [0002] In recent years, with the rapid development of the wind turbine power generation industry, various special semi-trailers with steering devices that are suitable for driving on curved roads in mountainous areas have emerged as the times require. The structural types of these steering devices mainly include single turntable type (referring to the steering device of ordinary trailers), multi-rod turntable type (referring to the steering device of hydraulic suspension trailers) and the wheel steering type in which each axle of a semi-trailer is driven by a steering drive cylinder. . The height of the cargo platform of the semi-trailer equipped with a single turntable steering device is relatively high; the manufacturing and use costs of a semi-trailer equipped with a multi-tie-rod turntabl...
