Mechanical hydraulic dual-mode-driven chassis of sanitation vehicle

Abstract

The invention discloses a mechanical hydraulic dual-mode-driven chassis of a sanitation vehicle. The chassis comprises a second type chassis body, a controller, a power take-off device, a belt pulley, a belt pulley flange, a variable displacement piston pump, a variable displacement piston pump flange, a transmission shaft, a clutch and a driving motor; the controller controls all units on the chassis through an electric control system; the input end of the power take-off device is connected with an engine of the second type chassis body, the controller controls the power take-off device to be connected and disconnected with the engine of the second type chassis, the belt pulley flange and the variable displacement piston pump flange are arranged at the two output ends of the power take-off device respectively, a special operation device is driven through a belt, the input end of the variable displacement piston pump is connected with the variable displacement piston pump flange, and the driving motor fixed to a rear suspension of the second type chassis body is driven through an oil tube; the driving motor is connected with the transmission shaft through the clutch, and the controller controls union and separation of the clutch; the transmission shaft drives a rear axle from the rear end of the rear axle of the second type chassis. The mechanical hydraulic dual-mode-driven chassis of the sanitation vehicle has the advantages of being easy to operate, low in oil consumption, low in emission and high in space utilization rate.

Description

technical field [0001] The invention relates to a sanitation vehicle chassis, in particular to a sanitation vehicle mechanical hydraulic dual-mode drive chassis. Background technique [0002] At present, urban road cleaning operations have been basically mechanized and completed by road cleaning vehicles. Existing road sweeping vehicle generally adopts second class chassis to refit, and uses double-engine configuration, and chassis engine is used for driving vehicle travel, and secondary engine is used for driving special-purpose operating device operation. The disadvantages of the sanitation vehicle chassis with this structure are: first, a series of actions such as vehicle speed control, gear shifting, auxiliary engine speed control, and special operating device control are all completed by the driver, resulting in driver fatigue; second, the fuel consumption of the dual-engine configuration High emissions, high emissions, and the installation of auxiliary engines takes u...
