The invention discloses an all-wheel steering mechanism of an eight-wheel vehicle. The all-wheel steering mechanism of the eight-wheel vehicle comprises a steering oil cylinder, tie rods are connected to the left side and the right side of the steering oil cylinder respectively, steering connecting rod mechanisms are connected to the upper side and the lower side of each tie rod respectively, each steering connecting rod mechanism comprises a steering large arm and a steering small arm, each steering large arm and each steering small arm are connected through a long pull rod, and each steering large arm and each steering small arm are further connected with wheel steering shafts respectively. The steering oil cylinder pulls the tie rods left or right, the tie rods drive the steering connecting rod mechanisms, and the steering connecting rod mechanisms drive wheels of the vehicle to steer left or right through the wheel steering shafts. According to the all-wheel steering mechanism of the eight-wheel vehicle, the steering mechanism of the eight wheels is designed in an integrated mode, the structure is simple, distribution is easy, the effects that main parameters of the steering mechanisms are adjustable, and all-wheel steering is free of sideslip are achieved, and the problem that the sideslip occurs when a multi-axle vehicle steers and the radius of a turning circle is large are solved effectively.
Description
technical field [0001] The invention belongs to the technical field of vehicle steering mechanisms, and relates to an all-wheel steering mechanism of an eight-wheel vehicle. Background technique [0002] During the steering process of the vehicle, the turning angle relationship of the left and right wheels on the same axle is realized by the steering trapezoidal mechanism on the axle. Therefore, the design of the steering trapezoidal mechanism directly affects the stability of vehicle handling, the safety of operation and the service life of tires. The main task of its design is to ensure that all wheels rotate around the same instantaneous steering center during the steering process of the vehicle and that there is a large enough turning angle to meet the minimum turning radius requirements. The use of all-wheel steering is the best way to solve the problem of large turning radius and steering slippage of multi-axle vehicles. It can reduce the turning radius of the vehicle...
