Abstract
The utility model discloses a front suspension system of a mining dump truck. The front suspension system is characterized by being composed of a truck frame (1), a lower traction bar (2), an upper traction bar (3), a front axle (5), a hydro-pneumatic suspension cylinder (7) and a transverse traction bar (8). The front axle (5) is connected with the truck frame (1) through the lower traction bar (2) and the upper traction bar (3), the two ends of the lower traction bar (2) and the two ends of the upper traction bar (3) are connected with the truck frame (1) respectively through first pin shafts (4), and then the front axle (5) can move vertically. The front axle (5) is connected with the truck frame (1) through the transverse traction bar (8) to limit the horizontal movement of the front axle (5). The upper end and the lower end of the hydro-pneumatic suspension cylinder (7) are connected with the truck frame (1) and the front axle (5) respectively through second pin shafts (6). The front suspension system is a non-independent suspension system adopting the hydro-pneumatic suspension cylinder; due to the adoption of the hydro-pneumatic suspension cylinder, bearing capacity is improved, the front suspension failure rate is decreased, and the comfort of the truck is improved.
Description
Technical field:
The utility model relates to mine vehicle technical field, is a kind of front suspension of quarry tipper specifically, is specially adapted to 6 * 4 quarry tippers.
Technical background:
At present, for quarry tipper, steel spring, because of its technology maturation, cheap, is used widely on 6 * 4 quarry tippers.But the load-carrying capacity of steel spring is less, vehicle is restricted toward maximization future development, and in use steel spring fault rate is higher, often there is part, affect the use of vehicle; In addition, be to improve load-carrying capacity, steel spring such as is designed at the stiffness structure more, causes the damping effect of vehicle when zero load poor, affects vehicle riding comfort.
Utility model content:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and the front suspension of quarry tipper is provided, and mainly solves that existing quarry tipper load-carrying capacity is low, fault rate is higher and the problem such as traveling comfort is poor.
The technical solution of the utility model is: a kind of front suspension of quarry tipper, and its special character is that it is comprised of vehicle frame, lower thrust rod, upper thrust rod, propons, pneumatic cylinder, lateral rod; Described propons is connected by lower thrust rod, upper thrust rod with vehicle frame, and lower thrust rod, upper thrust rod two ends connect by the first bearing pin respectively, propons up-and-down movement; Propons is connected by lateral rod with vehicle frame, the side-to-side movement of restriction propons; The upper and lower two ends of pneumatic cylinder are connected with propons with vehicle frame by the second bearing pin respectively.
Compared with the prior art the front suspension of a kind of quarry tipper described in the utility model has following good effect: 1, pneumatic cylinder is applied on 6 * 4 quarry tippers, improves load-carrying capacity, reduce the fault rate of forward mounting; 2, adopt pneumatic cylinder, improve vehicle riding comfort.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Drawing explanation:
1 vehicle frame, 2 lower thrust rods, 3 upper thrust rods, 4 first bearing pins, 5 propons, 6 second bearing pins, 7 pneumatic cylinders, 8 lateral rods.
The specific embodiment:
For Comprehension and Implementation better, below in conjunction with accompanying drawing, provide specific embodiment and describe the utility model in detail, illustrated embodiment, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment 1, referring to Fig. 1, Fig. 2, by lower thrust rod 2, upper thrust rod 3 for designing requirement, propons 5 is connected with vehicle frame 1, lower thrust rod 2, upper thrust rod 3 two ends connect by the first bearing pin 4 respectively, thereby guarantee that propons 5 can up-and-down movement, and keep certain attitude, prevent from turning over bridge; Propons 5 is connected to the side-to-side movement of restriction propons 5 by lateral rod 8 with vehicle frame 1; Pneumatic cylinder is connected with propons 5 with vehicle frame 1 by the second bearing pin 6 respectively at two ends Shang Xia 7, makes propons 5 when up-and-down movement, can subdue vibration by pneumatic cylinder 7; Form a kind of dependent suspension that adopts pneumatic cylinder.
The front suspension of a kind of quarry tipper described in the utility model, during work, by pneumatic cylinder, propons is subject to impacting and passes to vehicle frame, the impact that propons is subject to that decays of the motion of the hydraulic oil by oleo-pneumatic suspension cylinder interior simultaneously, in addition for guaranteeing the relative motion of vehicle frame and propons, by upper lower link, transmit longitudinal force, by lateral connecting rod, transmit transverse force.In addition, the rigidity of pneumatic cylinder is nonlinear, at full load, and the amount of compression of pneumatic cylinder is large, and it is large that rigidity becomes, and can improve vehicle load-carrying capacity; When unloaded, the speed of a motor vehicle is higher, and the amount of compression of pneumatic cylinder is little, and rigidity is little, can improve the traveling comfort of vehicle.
