Hinging-type dump truck chassis

Abstract

The invention discloses a hinging-type dump truck chassis. The hinging-type dump truck chassis comprises a steering system, a braking system, a drive system and a driving system, wherein the driving system comprises a truck frame assembly, the truck frame assembly comprises a front truck frame, a hinging body and a rear truck frame, a front axle is arranged below the front truck frame, a middle axle and a rear axle are arranged below the rear truck frame, one end of a left front hydro-pneumatic suspension unit and one end of a right front hydro-pneumatic suspension unit are connected to the upper surfaces of the left side and the right side of the front axle respectively, the other end of the left front hydro-pneumatic suspension unit and the other end of the right front hydro-pneumatic suspension unit are connected with the front truck frame, a right front cross pull rod, a front V rod and a left front cross pull rod are installed between the front truck frame and the front axle, themiddle axle is connected with the rear axle through a left balancing beam and a right balancing beam, a right middle cross pull rod, a middle V rod and a left middle cross pull rod are installed between the rear truck frame and the middle axle, and a right rear cross pull rod, a rear V rod and a left rear cross pull rod are installed between the rear truck frame and the rear axle. The hinging-typedump truck chassis is simple in structure, safe and reliable, and can effectively improve the trafficability and the comfort of the complete machine.

Description

technical field [0001] The invention specifically relates to an articulated dump truck chassis, which belongs to the field of mining machinery. Background technique [0002] Articulated Dump Truck (Articulated Dump Truck) is compared with Rigid Dump Truck (Rigid Dump Truck), which adopts the type of hinged front and rear frames. It is widely used in construction, roads, mines, ports and other engineering fields. Its function is to carry out Transportation operation, transport sand, rock, ore, coal and other materials to the target location. Due to the complexity of the operating conditions of the articulated dump truck, it has been running on potholes, water, bumpy roads, and even non-road conditions for many years, which puts forward higher requirements for the performance of the articulated dump truck chassis. Currently, articulated dump trucks on the market have many problems in the design and matching of chassis components, such as heavy chassis, complex frame structure...

AI Technical Summary

Problems solved by technology

The articulated dump trucks currently on the market have many problems in the design and matching of chassis components, such as heavy chassis, complex frame structure design, poor workmanship, low transmission efficiency, and insufficient suspension comfort.
