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 steering device for a wheel-steering semi-trailer, which comprises a wheel shaft, a steering wheel and a drive system. A mounting seat is arranged in the middle of the wheel shaft. The pin shaft is hinged with the steering seat. The steering seat includes a horizontal plate and a longitudinal plate with an integrated structure. The middle part of the horizontal plate and the front part of the longitudinal plate are both hinged with the vertical pin shaft. The ends are hinged, and the adjacent transverse plates are connected by longitudinal tie rods. The longitudinal tie rods are arranged in a staggered manner. There are two connecting parts on the rear edge of the longitudinal plates. When the axle of the semi-trailer deviates during operation, you only need to operate the steering drive cylinder to adjust the front axle, and the rear axle will be adjusted accordingly through the longitudinal tie rod, which can better adapt to the bending of the fan tower transported by the semi-trailer Running on mountain road.

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...
