Embodiment approach

[0047] Such as figure 1 figure 2 As shown, the first embodiment is: when the connecting shaft 4 at the upper end of the second universal joint 3 and the lower part of the axial column 7 are connected by folding the fixing frame 5 to realize the separation of the folded part, the second universal joint 3 and the axial column 7's indirect connection. The folding fixing frame 5 is similar to an inverted F shape, the upper end of the inverted F-shaped folding fixing frame 5 is connected to the positioning member 6, and the two lateral ends of the inverted F-shaped folding fixing frame 5 are respectively connected to the axial direction from top to bottom. The lower connection point 73 on the lower part of the column 7 is connected to the shaft 4 . Such as image 3 As shown, the connecting shaft 4 specifically includes a housing 42 , a bearing 43 and a rotating shaft 44 , and the connecting shaft 4 is fixedly connected to the folding fixing frame 5 through the housing 42 . It ...

Abstract

The invention discloses a foldable steering control system. The system comprises a first universal joint, a transmission shaft, a second universal joint, a steering column and a steering wheel which are connected from bottom to top, wherein the lower end of the first universal joint is fixedly connected with an input end of a steering gear, and a folding assembly is connected between the second universal joint and the steering column and comprises a separable folding part, a folding fixing frame and a positioning member connected with the steering column, wherein the separable folding part isarranged between the second universal joint and the steering column, and the folding fixing frame is fixed to the front wall of a cab and movably connected with the steering column. When the steeringcontrol system is folded, the steering column rotates outwards with the lower connecting point of the steering column as a rotating fulcrum, the positioning member moves at the same time, and the folding part is separated. When folding is completed, the positioning member stops moving, and the supporting steering column maintains the folding angle. According to the system, the steering wheel can be folded into an instrument desk, and correspondingly the convenience for a driver to get in or get out of a vehicle is improved. The steering control system can also be combined with the electric power-assisted steering gear for use to achieve unmanned driving, and the scientific and technical performance of the vehicle is improved.

Description

technical field [0001] The invention relates to a vehicle steering control system, in particular to a foldable steering control system, which belongs to the technical field of vehicle mechanical transmission. Background technique [0002] The function of the car steering system is to control the driving direction of the car according to the driver's wishes. Automobile steering system is very important to the driving safety of automobiles. However, in order to make the automobile steering system meet the needs of different drivers for driving adaptability and comfort, the prior art usually swings the steering system up and down by a certain angle, and expands and contracts axially by a certain distance to meet the corresponding requirements. [0003] The Chinese utility model patent with the patent number "201520383972.3" and the patent title: "A Foldable Steering Control System" discloses a foldable steering control system, including a first universal joint, a telescopic sh...
