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 connected on 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 cylinder connecting 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...
