Types and structures of Petrol Car accessories steering gear

There are currently many types of Petrol Car, and steering gears of various structural forms are also used in Petrol Car. There is currently one type. Worm crank sales formula. Circulating spherical rack-toothed fan. Recirculating ball crank sales formula. Worm rolling and other forms, while worm rolling is rare, only representative racks and racks are introduced below. Worm crank sales formula.

The gear machine has very high forward efficiency and reverse efficiency. It is a reversible reverser and has a strong ability to automatically return to the forward direction. However, due to the large reverse impact of this form of steering gear, a soft universal joint is usually installed between the driving gear and the steering shaft, or a lateral shock absorber is installed in the front axle to absorb the impact energy and reduce the impact on the driver. injury to personnel.
When the steering gear is behind or is too large, the rack and pinion gap must be adjusted. The adjustment method is: put the wheel on the ground, in the straight driving position, loosen the lock nut, and tighten the adjusting bolt inward until the adjusting bolt touches the pressure block. Check that the steering wheel should be in a gap-engaged state and rotate flexibly. After adjustment, tighten the locking nut.
The recirculating ball steering gear is one of the most widely used structural types at home and abroad because it is easy to operate and has a long service life.
But its reverse efficiency is also very high, and it can easily transmit the impact force of the ground against the steering wheel to the steering wheel. If a Petrol Car is driven regularly on good roads, the above disadvantages will have little impact.
This kind of steering gear is suitable for domestic Geely Car, such as CA1040, CA1092, Beijing BJ1041, Huanghe JN1811C13, etc.
Recirculating spherical steering gear generally has two levels of transmission pairs, the first level is a spiral nut transmission pair, and the second level is a rack and pinion sector transmission or sliding transmission.
