Embodiment Construction

[0016] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0017] The invention provides a double-wishbone front suspension of a non-highway mining dump truck.

[0018] Such as figure 1 As shown, the device includes an upper tie rod 1, an upper wishbone 2, a pin 3, an oil-pneumatic suspension cylinder 4, a lower wishbone 5, a bearing seat 6, a joint bearing 7 and an oil-pneumatic suspension piston rod 8, and the upper wishbone 2 and the lower wishbone The yoke 5 is respectively hingedly installed on both ends of the oil-air suspension cylinder 4 and is hinged with the vehicle frame. The oil-air suspension piston rod 8 is slidingly connected with the oil-air suspension cylinder 4 through the joint bearing 7. The joint bearing 7 is installed on the bearing seat 6, and the upper pull rod One end of 1 is hinged wit...

Abstract

The invention provides a double-fork-arm type front suspension of an off-highway mining dump truck, and belongs to the technical field of automobiles. The front suspension comprises an upper pull rod,an upper fork arm, a pin, a hydro-pneumatic suspension cylinder barrel, a lower fork arm, a bearing seat, a knuckle bearing and a hydro-pneumatic suspension piston rod, the hydro-pneumatic suspensioncylinder is connected with a frame, the upper fork arm and the lower fork arm are hinged to the two sides of the hydro-pneumatic suspension cylinder barrel, and the hydro-pneumatic suspension pistonrod is in sliding connection with the hydro-pneumatic suspension cylinder barrel. The upper pull rod is hinged to the hydro-pneumatic suspension piston rod and the frame. The double-fork-arm type front suspension for the heavy-duty car is simple in structure, the system can adopt hydro-pneumatic suspension with small diameter and stroke, the suspension has the functions of a main pin, an elastic element and a damping element at the same time, the lateral stability of the car is enhanced, and the space utilization rate of a front axle and the flexibility of a steering system are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a double-wishbone front suspension of an off-highway mining dump truck. Background technique [0002] Off-highway mining dump trucks are mainly used for the mining and stripping of rock and soil materials and the transportation of ores in open-pit mines. The working distance is generally short, the load capacity is large, and the environment is harsh. Therefore, the rigidity, damping, and suspension movement Due to high requirements on mechanical characteristics and reliability, it is necessary to be equipped with a highly integrated and high-performance independent front suspension system. [0003] Large off-highway mining dump trucks all use oil-pneumatic suspension, mainly column suspension type. Not only is the structure simple, the oil-pneumatic suspension of the front wheel also serves as the kingpin, but it also has the following disadvantages: oil-pneumatic suspension...
