Embodiment 1

[0039] Such as figure 1 with figure 2 As shown, this embodiment provides a gradient adjustable steering column. The top of the steering column is connected to the steering wheel through the steering shaft, and the bottom of the steering column is connected to the ball telescopic bushing assembly 10 through the constant velocity universal joint assembly 9 . The ball telescopic bushing assembly 10 is connected to the intermediate shaft 12 through the universal joint assembly 11, the intermediate shaft 12 is connected to the lower universal joint assembly 13 through bolts, the lower universal joint assembly 13 is connected to the steering gear, and the column tube 8 An ignition lock hole 81 and a flange 82 are arranged on the top, the ignition lock hole 81 is connected with the automobile ignition lock, and the flange 82 is connected with a combination switch, a sensor, and a clock spring.

Embodiment 2

[0046] Such as Figure 4 with Figure 5 As shown, this embodiment is further optimized on the basis of Embodiment 1, specifically including a pneumatic delay valve 21, the output end of the pneumatic delay valve 21 is connected to the cylinder 6, and the input end of the pneumatic delay valve 21 is connected to the automobile Air connection.

[0047] The principle of use of the pneumatic delay valve 21: when the driver touches the unlocking button of the pneumatic delay valve 21, the air source of the vehicle will quickly enter the interior of the one-way valve cavity, and the air pressure pushes the inner copper rod valve sleeve. After the spring is compressed, the gas directly Through the air outlet pipe, it directly flows into the booster cylinder 6 at the tail end, pushes the spring to compress, the piston of the cylinder 6 is retracted and unlocked successfully, and the adjustment mechanism can be adjusted freely. After unlocking for a certain period of time, the air va...

Embodiment 3

[0049] Such as Figure 7 , Figure 8 with Figure 12 As shown, this embodiment is further optimized on the basis of Embodiment 2. Specifically, the initial angle between the center line of the column tube 8 and the horizontal plane is 50 degrees, the central angle corresponding to the arc-shaped through groove is 35 degrees, and the long bolt 14 The initial position is located in the middle of the arc-shaped through groove, the length of the chute 18 is 70 cm, and the bottom surface of the contour limiting plate 19 is curved.

[0050] Set the angle between the center line of the column tube 8 and the ground plane to 50 degrees, that is, set the reference man-machine angle to 50 degrees, compared with the 75-80 degrees used in batches of domestic automobile column assemblies and the 65-80 degrees of some commercial vehicles. 70, can reduce the angle between the driver's body and the ground plane, make the driver's reclining angle larger, closer to "lying down" driving, improv...

Abstract

The invention discloses a gradient adjusting steering column and relates to the technical field of vehicle steering control devices. The gradient adjusting steering column comprises an installation support assembly, left and right supporting boards, left and right spring supports, height buffer springs, angle buffer springs, an air cylinder, a balance support and a column pipe. Sliding grooves forthe left and right spring supports to slide are formed in the left and right supporting boards, profile limiting boards are arranged between the installation support assembly and the left and right spring supports and fixedly connected with the installation support assembly, arc-shaped through grooves for long bolts to rotate are formed in the profile limiting boards and the installation supportassembly, and limiting pins used for limiting the rotation angle of the installation support assembly are further arranged at the lower ends of the left and right supporting boards. The gradient adjusting steering column has the beneficial effects that adjustment is convenient to and reliable, and the driver figure application range is wide.

Description

technical field [0001] The present invention relates to the technical field of vehicle steering control devices, and more specifically relates to a gradient-adjustable steering column. Background technique [0002] The driver of the car realizes the change of the direction of the vehicle by manipulating the steering wheel, and the manipulation of the steering wheel is the main control part that cannot be separated from the hand when driving the vehicle. The steering column assembly of an automobile is a crucial safety component in the driving process of the automobile. Its main function is to control the driving direction of the automobile according to the driver's wishes, and at the same time realize four-way adjustable. The mounting bracket body is fixed on the dash panel of the cab body, the top end is connected with the steering wheel, and the tail end is connected with the steering gear. The driver operates the steering wheel, the steering wheel directly transmits the ...
