Description

A New Type of Slewing Bearing Steering Wheel

technical field

The invention relates to the technical field of steering wheels, in particular to a novel slewing bearing steering wheel.

Background technique

The first cars were driven with rudders. It transmits the violent vibration generated during the driving of the car to the driver, making it more difficult for him to control the direction. When the engine was changed to be installed in the front of the car, due to the increase in weight, the driver could no longer use the rudder to drive the car. The new design of the steering wheel came into being. It introduced a gear system between the driver and the wheel that was flexible in operation and well isolated from the violent vibrations from the road. Not only that, a good steering wheel system can also bring the driver a feeling of intimacy with the road.

Most of the car GPS screens in the prior art are fixedly installed on the steering wheel or set between the main driver and the co-pilot, and the driver needs to turn his head to see it between the main driver and the co-pilot, so it is easy to see Causing safety hazards, the GPS screen is fixed on the steering wheel and the screen will rotate with the steering wheel when turning, which affects the driver's observation of the screen, which is also dangerous.

There is a Chinese authorized patent: CN205769065U, a steering wheel with a display screen. In this utility model patent, information such as speed and GPS can be displayed in real time during the driving process of the car, so that the driver does not need to turn his head to look at the GPS screen in the middle of the vehicle. It can grasp the vehicle condition at any time. When reversing, the screen automatically switches to the rear camera image, which is convenient for reversing. The left and right corresponding rearview mirror rockers can adjust the angles of the rearview mirrors on both sides without leaving the keyboard. The horn contact allows the driver to just press the thumb, and the direction indicator on the steering wheel indicates the current direction light status at any time, reminding the driver to turn off the direction light at all times to avoid traffic problems. However, in this patent, the screen is fixed on the steering wheel, which is inconvenient to observe during the rotation process, and it is easy to cause safety accidents.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

1-3, a new type of slewing bearing steering wheel includes a support 1, a slewing bearing 14 and a main shaft 100. The support 1 is fixedly connected to the inner ring of the slewing bearing 14, and the outer ring of the slewing bearing 14 is fixedly connected by screws. There is a rotating sleeve 2, the outer wall of the rotating sleeve 2 is fixedly provided with a control panel 3, and the inner wall of the rotating sleeve 2 is fixedly provided with a gear ring 8; the inner ring of the slewing bearing 14 is also fixed with a gear mounting plate 11 by screws , the gear mounting plate 11 is provided with a transmission mechanism, the ring gear 8 is connected with a driven gear 12 through the transmission mechanism, and the driven gear 12 is sleeved on the outside of the main shaft 100; , the top of the pillar 6 is fixed with a cover plate 4 by bolts, and a display screen 5 is installed on the top of the cover plate 4 .

Through the arrangement of the cover plate 4, the display screen 5, the pillar 6, the shield 7, the ring gear 8, the first transmission gear 9, the second transmission gear 10 and the slewing bearing 14, a slewing bearing 14 is added inside the traditional steering wheel, The control panel 3 rotates through the slewing bearing 14, and uses the transmission mechanism to transmit the manipulation of the steering wheel. The inner ring of the slewing bearing can be used to fix the cover plate 4 for installing the screen. When the steering wheel is turned, the display screen 5 will remain fixed. It rotates with the steering wheel to ensure that personnel can observe and avoid the possibility of accidents due to viewing the display.

In this embodiment, the top of the gear mounting and fixing plate 11 is fixed with a blocking cover 7 by screws, and the blocking cover 7 is located outside the transmission mechanism.
