Embodiment Construction

[0033] Attached below Figure 1-4 , The content of the present invention is further detailed as follows:

[0034] The invention is a steering mechanism that can realize that the inner and outer wheel rotation angles conform to the Ackerman rotation angle relationship. It includes a steering motor 1, a deceleration device 2, a rotation reversing device 4, a rotation same direction device 13, a left drive shaft M3, Right drive shaft N12, spindle O5, spindle P14, connecting rod AB6, connecting rod BG7, connecting rod CD8, connecting rod DE9, steering arm EF10 and steering knuckle 11, such as figure 2 Shown.

[0035] Between the steering power source and the spatial linkage mechanism, a plane linkage mechanism is designed. The hinge points A and C are fixedly installed on the frame and rotate around the hinge point A as the road surface changes. When the steering wheel does not rotate, the steering motor 1 does not rotate, that is, when the connecting rod AB6 does not rotate, as the ...

Abstract

The invention discloses a steering mechanism capable of solving the steering problem of a vehicle with a balance rocker arm type chassis. The steering mechanism comprises a steering motor, a speed reduction device, a rotation motion reversing device, a rotation motion homodromous device, a left transmission shaft M, a right transmission shaft N, a mandrel O, a mandrel P, a connecting rod AB, a connecting rod BG, a connecting rod CD, a connecting rod DE, a steering arm EF and knuckles. The steering motor provides steering power, opposite motions in the same size are transmitted to planar connecting rod mechanisms on the two sides after speed reduction through the speed reduction device and then pass through RSSR spatial connecting rod mechanisms, and the ideal Ackerman steer angle relation of steer angles of inner steering wheels and outer steering wheels of the vehicle is achieved. The planar connecting rod mechanisms and the RSSR spatial connecting rod mechanisms are arranged on the wheel edges, so that the chassis space between the steering wheels can be reduced. Steering of left vehicle wheels and right vehicle wheels is achieved through the steering mechanism, and control difficulty is lowered.

Description

【Technical Field】 [0001] The invention relates to a spatial linkage steering mechanism, in particular to a steering mechanism capable of realizing the Ackerman angle relationship, and belongs to the technical field of mechanical engineering. 【Background technique】 [0002] The balanced rocker chassis vehicle can better adapt to the complex terrain of hilly and mountainous areas, and can automatically adapt to the uneven complex ground, realize the attitude adjustment of the whole machine, and reduce the front and rear pitching amplitude of the vehicle body caused by the deflection of the ground to the vehicle body . Because the chassis uses a rocker arm mechanism, while realizing the functions of variable ground clearance and variable attitude, the wheelbase and wheelbase of the vehicle will also change accordingly. The traditional steering trapezoidal mechanism will cause steering interference problems. [0003] At present, in response to these existing problems, commonly used so...
