Abstract
The invention discloses a wind pressure adjuster and a vehicle speed reducer. The wind pressure adjuster comprises a base. The top of the base is provided with a terminal board and a body. The opposite sides of the terminal board and the machine body are connected through a supporting rod. A plurality of normally closed end screws, normally open end screws and common negative end screws are longitudinally arranged on the terminal board in a penetrating manner; the rear end of each normally-closed end screw is provided with a normally-closed end contact screw and a locking screw. The rear end of each normally open end screw is provided with a normally open end contact screw and a locking screw. The front ends of the plurality of normally closed end screws are connected with the normally closed end connecting sheet; the front ends of the plurality of normally open end screws are connected with the normally open end connecting sheet; the machine body comprises a fixed column; a column body inner hole is formed in the fixed column; the fixing column is provided with a plurality of spring tubes; an air inlet, a water drainage hole and a plurality of air outlets which are communicated with the inner hole of the column body are formed in the fixed column; and each air outlet hole is communicated with the inner cavity of one spring tube. The air pressure adjusting precision can be improved, and the pressure value of compressed air entering the speed reducer air cylinder can be accurately controlled.
