Double steering rigid suspended car axle assembly

Abstract

The invention relates to a double steering rigid suspended car axle assembly, characterized in that: a vertical axle assembly (4) is hinged with a vertical axle (9), a steering arm (1) is fixed onto the vertical axle (9) and is connected with a shaft (2), which one end is hinged with crankarms (3), a tie rod (6) is hinged between the two crankarms (3), the vertical axle (9) is hinged with the axle (12) via a pin (11). According to the invention, synchronous steering of the vertical axle around the vertical axle assembly, and the swinging of the axle relative to the vertical axle can be achieved based on the swinging of a balance beam around a tripod center. The invention has the following advantages: the steering radius of the car is small, the use is flexible; the force of each axle is the same, that is to say, the force of each tyre is uniform, thereby protecting the road face and keeping the stability of the car loading table; meanwhile, one car can be matched with and used for the other cars.

Description

[0001] Technology fields:

[0002] The present invention relates to transportation equipment and in particular to the use of suspended axles in heavy, large vehicles or mobile platforms. Background technique:

[0003] Ordinary rigid suspension axle assembly (one-line two-axle assembly) is composed of balance beam assembly, axle assembly, tripod assembly, sleeve, pin and other components. Generally, two sets are used as a set, widely used in heavy-duty semi-trailers, and most of the same vehicles are equipped with one set. The tripod assembly is connected with the balance beam of the vehicle. When the vehicle passes on an uneven road, the tires of the four axles can be stressed, that is, the axle assembly can swing horizontally around the balance beam assembly, and the balance beam can swing longitudinally around the tripod, so that the front and rear The axle assembly floats up and down. At the same time, each set of products can hold 16 tires, which increases the contact ar...

Embodiment Construction

[0012] Such as figure 1 , figure 2 As shown, the double steering rigid suspension axle assembly provided by the present invention includes the original balance beam 7 and the connected tripod 8, and the two ends of the balance beam are connected with the vertical shaft assembly 4 respectively, so that the balance beam can swing up and down around the center of the tripod .

[0013] The present invention is characterized in that: each vertical shaft assembly 4 adopts a bearing to movably connect the vertical shaft 9, and each vertical shaft 9 is fixedly connected with a steering arm 1 and a reinforcing arm 1a, and each steering arm 1 and the reinforcing arm 1a are jointly connected with a rotating shaft 2. The upper end of each rotating shaft 2 is hinged to a crank arm 3, and the left and right crank arms 3 are respectively hinged to a pull rod 6 with a pin shaft 5. When the steering arm 1 on one side is powered, the vertical shaft 9 on both sides is driven to rotate synchro...
