Mechanical space electric lifting mechanism of dump truck

Abstract

The invention relates to a mechanical space electric lifting mechanism of a dump truck. The mechanism comprises a frame, a hopper, a driving rod, a connecting rod, a speed reducer and a motor, wherein one end of the driving rod is connected with the frame through a first rotation pair, and the other end is connected with the connecting rod through a first spherical pair; the other end of the connecting rod is connected with the front end of the hopper through a second spherical pair; the rear end of the hopper is connected with the frame through a second rotation pair; and the driving rod is driven by the motor through the speed reducer. The mechanism provided by the invention is driven by the motor and transmitted by the connecting rod, can effectively overcome the shortcomings of high processing assembly requirements, short service life, oil leakage, high maintenance cost and the like of the parts of a hydraulic system of a traditional hydraulic dump truck, and has good dynamic and static performance and large working space.

Description

technical field [0001] The invention relates to the field of engineering dump trucks, in particular to a mechanical space electric lifting mechanism for dump trucks. Background technique [0002] A dump truck is a special vehicle that installs a lifting mechanism on the chassis, uses the lifting mechanism to tilt the compartment at a certain angle to unload, and relies on the self-weight of the compartment to reset it. The existing dump trucks are all hydraulic transmission type, which has the advantages of simple structure and large lifting force, but its hydraulic system has the disadvantages of high processing and assembly requirements for hydraulic components, difficult maintenance, high manufacturing cost, etc., and the hydraulic oil is greatly affected by temperature. , The overall efficiency is low, and the leaked hydraulic oil will cause environmental pollution, which seriously restricts the application and promotion of dump trucks. Moreover, due to the limitations ...
