Problems solved by technology

When this kind of vehicle is used on the construction site, due to the poor road conditions on the construction site, the softness and hardness of the road surface on which the vehicle is driving, the large resistance coefficient of the surface road, the high working intensity and severe overloading, the upper thrust rod often breaks, which causes long-term drive axles to move, mid The drive shaft of the rear axle is damaged, and the distribution of the suspension thrust rods cannot meet the requirements of the construction site.
[0006] 4. The traditional balance suspension is a single-leaf spring structure, that is, the middle of the leaf spring is fixed on a balance shaft
The existing problems are loud noise, heavy weight, and poor economical performance of the vehicle
[0008] 6. The traditional connection method of the oil cylinder for engineering vehicles is to directly connect the brackets at both ends of the oil cylinder to the front plate of the cargo box. This connection method has three disadvantages: 1. Drill 12 φ16.5 holes on the front plate of the cargo box. Holes, due to the heavy weight and large area of ​​the front plate of the cargo box, it is very inconvenient to process. Second, because the front plate of the cargo box is easily deformed when the cargo box is loaded, this will directly lead to changes in the installation position of the oil cylinder, making the oil cylinder The service life of the oil cylinder is reduced due to the additional force; third, because the bolts are directly connected to the front plate of the cargo box, the bolt heads are exposed inside the cargo box, and it is difficult to disassemble after being deformed or corroded by the impact of the cargo, which is not convenient for the oil cylinder Repair an

Embodiment 1

[0084] Example 1 as figure 1 with figure 2 As shown, this non-highway dump truck includes a car body, a frame, a power system, a transmission system, a carriage, tires, and a braking system. Its power system 1 is connected to the main frame 8, and the steering system 2 is connected to On the left front outside of the main frame 8, the suspension system 3 is connected below the main frame 8, the brake system 4 is connected to the inside and outside of the main frame 8, and the hydraulic cylinder of the lifting system 5 is connected to the On the front end of the subframe 9 and on the front plate of the cargo box 6, the cargo box 6 is connected to the subframe 9, the subframe 9 is connected to the main frame 8 through a bracket and a connecting plate, and the driver's cab 7 is connected to the main frame 8 through a bracket. Front left of the main frame.

[0085] It is aimed at the special working conditions of the construction site. Its power system matching design adopts a ...

Embodiment 2

[0097] Embodiment 2 is basically the same as Embodiment 1, and the difference is that its suspension is a balance beam suspension such as diagram 2-1 As shown, there are four rubber main springs 2-1 in total, two of which are connected to the two ends of the equalizing beam 2-4 on the left side of the vehicle frame 2-23 by bolts 2-2, and the other two are connected by bolts 2-2 to the The two ends of the equalizing beam 2-4 on the right side of the vehicle frame 2-23, and the bottom of the four rubber main springs 2-1 are respectively connected to the axle housing processing surfaces of the middle axle 2-18 and the rear axle 2-10 through bolts 2-11 The middle part of the balance beam 2-4 is connected to the two ends of the balance shaft 2-16 with rubber bearing 2-19, rubber bearing cover 2-20, and bolt 2-21, and the balance shaft 2-16 is fixed on the balance shaft support 2-14 Among them, the two balance shaft brackets 2-14 are respectively connected to the vehicle frame 2-23...

Embodiment 3

[0098]Embodiment 3 is basically the same as Embodiment 1, and the difference is that its suspension is another kind of suspension structure such as Figure 3-1 As shown, it is the longitudinal distribution diagram of embodiment 3, the upper thrust rod 3-1 and the lower thrust rod 3-13, the middle bridge 3-14 and the support 3-11, and the four balance beams 3-15 pass through the upper thrust rod beam end The connection of support 3-2, upper thrust rod bridge end support 3-4 and lower thrust rod support 3-9 forms two side-by-side four-bar linkages at the front end and rear end of four balance beams 3-15, which can effectively control Longitudinal runout of middle axle 3-14 and rear axle 3-16. The two ends of the four upper thrust rods 3-1 are respectively connected to the upper thrust rod beam end support 3-2 and the upper thrust rod bridge end support 3-4 by two bolts 3-17, and the upper thrust rod beam end support 3-2 is single The limit is connected on four beams 3-15 and th...

Abstract

The invention relates to a method for designing a self-discharging truck for off-highway working conditions, which is characterized in that a power system (1) is connected to a main vehicle frame (8); a steering system (2) is connected to the left front outside of the main vehicle frame (8); a suspension system (3) is connected below the main vehicle frame (8); a braking system (4) is connected to the inside and the outside of the main vehicle frame (8); a hydraulic cylinder of a lifting system (5) is connected to the front end upside of an auxiliary vehicle frame (9) and a front plate of a cargo tank (6) through a cylinder connecting seat; the cargo tank (6) is connected to the upside of the auxiliary vehicle frame (9); the auxiliary vehicle frame (9) is connected to the upside of the main vehicle frame (8) through a bracket and a connecting plate; and a single edge of a cab (7) is arranged at the left front part of the main vehicle frame (8). The method defines a market for off-highway vehicles, determines technical index of the off-highway vehicles according to the determined market demand, simultaneously achieves the design of general layout according to the technical index, and mainly solves a vehicle ground system under an off-highway state.

Description

technical field [0001] The invention relates to a dump truck used in off-highway working conditions, in particular to the design of a dump truck for off-highway that can exert high transportation efficiency in short-distance transfer transportation of various open-air mineral materials under off-highway working conditions method. Background technique [0002] At present, for the specific market of bulk material transportation in domestic water conservancy and electric power construction sites, large-scale open-pit mines and other similar places, the construction site is relatively closed, the construction period is long, the transport materials are relatively stable, and the vehicles are heavily used and updated quickly. Mining vehicles in the engineering category are more suitable, but because of their high purchase and operating costs, project contractors purchase a small amount for qualification certification for bidding needs, and they are rarely used in practice; engine...
