Truck cooling and noise balance controlling rear regulating fan assembly

Abstract

The invention relates to a truck cooling and noise balance controlling rear regulating fan assembly including a rectangular outer frame, a plurality of regulating fan blades, a first rack, a second rack, a third rack, a fourth rack, a first motor, a second motor and an outer shield; the multiple regulating fan blades are rotatably arranged in the rectangular outer frame; the first motor and the second motor are separately fixed to two sides of the rectangular outer frame; and the first rack and the second rack are arranged at the rectangular outer frame in a relative sliding mode, the third rack and the fourth rack are arranged at the rectangular outer frame in a relative sliding mode, and the outer shield is fixed to the rectangular outer frame. According to the technical scheme, througha first linkage gear, the first rack, the second rack, the third rack and the fourth rack of the motor and a first linkage gear structure of each of the regulating fan blades, real time regulating offan blade opening angle can be realized according to the operating conditions of vehicle noise and cooling to achieve the aims of balancing the vehicle cooling and noise.

Description

technical field [0001] The invention belongs to the technical field of engine heat and noise balance system, in particular to a truck cooling and noise balance control rear regulating fan assembly. Background technique [0002] Usually, in order to solve the noise problem of trucks and reduce noise, the method of arranging sound-absorbing cotton around the engine and cooling system is used to reduce the noise from the crank connecting rod movement mechanism inside the engine and the noise of the cooling system (the noise of the cooling system is mainly generated by the cooling fan; in When the size of the radiator is determined, the method of increasing the fan speed is usually used to improve the heat dissipation effect, the higher the engine coolant temperature is, the higher the fan speed) [0003] Such as figure 1 Shown is a schematic diagram of the conventional state without adding sound-absorbing cotton; figure 2 In order to increase the state diagram of the sound-a...
