Problems solved by technology

[0002] The truck suspension seat in the market now realizes the suspension function through transmission devices such as rolling wires to destroy the balance between the valve and the cam, thereby inflating and deflating the air spring. This adjustment method has a delay in action. time, imprecise, and difficult to achieve stepless adjustment

Embodiment Construction

[0014] see figure 1 , figure 2 , image 3 with Figure 4 As shown, this embodiment is composed of two cam fans 1 and an air valve 2, the two cam fans 2 are sheathed and fixed on the hinge shaft 3, the two cam fans 1 are arranged crosswise, and the air valve 2 is fixed on the lower section of the outer hinge bracket 4 Above, the two cam fans 1 are respectively in contact with the two valve stems 21 of the air valve 2; the surface where the cam fan 1 contacts with the valve stem 21 is an arc surface.

[0015] The working process of the present invention: the two cam fans 1 are respectively in contact with the two valve rods 21 of the air valve 2, and with the relative rotation between the inner hinge bracket 5 and the outer hinge bracket 4, the hinge shaft 3 and the air valve 2 move relatively , the two cam fans 1 control the operation of the air valve 2, and then control the inflation and deflation of the gas spring, and then control the suspension state of the seat. The c...

Abstract

The invention discloses a precisely-adjusted air suspension mechanism integrated valve. The precisely-adjusted air suspension mechanism integrated valve is composed of two cam fans and an air valve. The two cam fans are fixed to a hinge shaft in a sleeving mode, and are arranged in a staggered mode. The air valve is fixed to the lower segment of an outer hinge support, and the two cam fans are in contact with two valve rods of the air valve respectively. The hinge shaft and the air valve relatively move along with relative rotation between an inner hinge support and the outer hinge support. The two cam fans control the air valve to work so that inflation and deflation of an air spring are controlled, and then the suspension state of a seat is controlled. The contact faces of the cam fans and the valve rods are arc-shaped faces, and infinite adjusting can be achieved. Non-delayed precise infinite suspension adjusting can be achieved through opening and closing of an air channel.

Description

technical field [0001] The invention relates to a precisely regulated integrated valve of an air suspension mechanism. Background technique [0002] The truck suspension seat in the market now realizes the suspension function through transmission devices such as rolling wires to destroy the balance between the valve and the cam, thereby inflating and deflating the air spring. This adjustment method has a delay in action. It is imprecise and difficult to achieve stepless adjustment. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a precisely regulated integrated valve for the air suspension mechanism. [0004] The present invention is composed of two cam fans and an air valve, the two cam fans are sleeved and fixed on the hinge shaft, the two cam fans are intersected, the air valve is fixed on the lower section of the outer hinge bracket, and the two cam fans are respectively connected with the The two val...
