Problems solved by technology

[0014] It overcomes the problem that the longest leaf spring is easy to break caused by the unreasonable structure of the leaf spring skateboard seat of the engineering vehicle in use. It is not tight and can reduce wear and impact on the longest 3 pieces of the leaf spring and reduce pressure under off-highway working conditions. and the wear resistance below, thereby prolonging the life of the leaf spring

Embodiment 1

[0066] Example 1 as figure 1 and figure 2 As shown, this kind of non-highway dump truck that reduces wear and improves the service life of the leaf spring includes a car body, a frame, a power system, a transmission system, a car box, tires, and a braking system. Its power system 1 is connected to the On the main frame 8, the steering system 2 is connected to the left front outside of the main frame 8, the suspension system 3 is connected below the main frame 8, the braking system 4 is connected to the inside and outside of the main frame 8, and the lifting system The hydraulic cylinder of 5 is connected to the front end of the subframe 9 and the front plate of the cargo box 6 through the oil cylinder connecting seat, the cargo box 6 is connected to the subframe 9, and the subframe 9 is connected to the main frame through a bracket and a connecting plate 8 above, the cab 7 is connected to the left front of the main frame through brackets. It designs a new type of leaf sprin...

Embodiment 2

[0082] 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, 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 through bolts 2-2, and the other two are connected 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 through bolts 2-...

Embodiment 3

[0083] 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 t...

Abstract

The invention relates to an off-highway dump truck for reducing abrasion and prolonging service life of a plate spring. The off-highway dump truck is characterized in that: a power system of the dump truck is connected on a main frame; a steering system is connected on the left front outer side of the main frame; a suspension system is connected below the main frame; braking systems are connectedon the inner and outer sides of the main frame; a hydraulic cylinder of a lifting system is connected above the front end of a secondary frame and on the front plate of a cargo box through a cylinderconnecting seat, the cargo box is connected above the secondary frame, and the secondary frame is connected above the main frame through a bracket and a connecting plate; a cab is arranged on the left front part of the main frame on single side; the suspension system mainly comprises a front suspension system and a rear suspension system, the rear suspension system is provided with a new-type plate spring sliding plate seat, the seat body of the sliding plate seat has a framework-type structure, two ends of the lower surface of the upper plane of the seat body are downwards raised lower arc surfaces, and the middle of the seat body is a plane; and the upper surface of the lower plane of the seat body is an upwards raised upper arc surface. The invention defines the market of off-highway trucks, determines the technical indexes of the off-highway trucks according to the determined market requirements, and mainly solves a truck ground system in an off-highway state.

Description

technical field [0001] The invention relates to a dump truck used in off-highway working conditions, in particular to a dump truck capable of reducing wear and improving plate performance in short-distance transfer transportation of various open-air mineral materials under off-highway working conditions. spring life for off-highway dump trucks. 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 p...
