Abstract

The invention discloses a fan drive. A centrifugal fan, a fan impeller shaft and an engine output shaft of a small diesel engine are arranged coaxially, the centrifugal fan is fixed on an underframe, a connecting seat is arranged on the outer side of the fan impeller shaft, the centrifugal fan is connected with a bearing seat through hexagonal head bolts I, the bearing seat is connected with the connecting seat, the connecting seat is connected with a supporting seat flange through hexagonal head bolts IV, and the supporting seat flange is connected with the small diesel engine through hexagonal head bolts III; a clutch wheel is fixed on the fan impeller shaft through a flat key I; and a centrifugal clutch is fixed on a shaft sleeve of the output shaft of the small diesel engine through a flat key II. When the engine starts, the revolving speed of the output shaft is low, the clutch is not combined to the clutch wheel, and the engine can start in a no-load manner; and when the fan drive works, the engine is throttled up, the revolving speed is increased, the clutch is automatically combined to the clutch wheel, and transmission torque drives a fan impeller to rotate. The fan drive is reasonable in structure, stable in performance, relatively low in cost and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of transmission devices for vehicles, and in particular relates to a fan transmission device. Background technique [0002] As one of the sanitation equipment, the road sweeper is a new type of efficient cleaning equipment that integrates road cleaning, garbage recycling and transportation. The cleaning effect of the road sweeper depends largely on the selection of the fan. The larger the fan model, the greater the suction and the better the cleaning effect. The greater the air volume of the fan, the greater the power of the engine that needs to be selected. The existing road sweeper involves many parts and has a compact layout. The transmission device is usually positioned at the rear of the propulsion unit in the longitudinal direction and connected to one or more axles to drive the vehicle. [0003] A clutch device is designed in the transmission system in the prior art. For example, the patent name is ...
