Technical Field
The invention relates to a synchronous adjusting mechanism for eccentric bearings of a steering gear, which realizes synchronous eccentric adjustment of the eccentric bearings at two ends of a rocker shaft of the steering gear, and improves the assembly efficiency and the assembly and adjustment quality.
Background
At present, most rocker shafts of commercial vehicle steering gears are of helical tooth structures, steering clearance adjustment is axial clearance adjustment and is adjusted by means of adjusting bolts and side cover threaded structures which are installed in the axial position direction of the rocker shafts, during adjustment, adjusting screws of the rocker shafts are rotated to axially advance or retreat the rocker shafts, meshing clearances between the rocker shafts and rack-piston-gear pairs are controlled, and therefore the purpose of adjustment is achieved, and mechanical clearances of the whole set of steering gear mechanisms are controlled. The steering gear clearance adjusting device with the structure is simple, the clearance of the gear pair can be adjusted only by one inner hexagonal wrench, but the steering gear with the structure cannot realize the output of the gear ratio.
The utility model discloses a commercial vehicle steering gear for realizing the output of a gear ratio, which realizes that the gear ratio structure adopts two eccentric bearings to adjust the meshing clearance between a rocker arm shaft and a rack piston, and the whole adjusting process needs to ensure the synchronous adjustment of the two eccentric bearings, otherwise, the rocker arm shaft is easy to generate early wear in the rotating process, and oil leakage and steering clamping stagnation are caused when an oil seal is damaged; the output force of the steering gear is weakened, the aligning moment is increased abnormally, and the bearing is damaged abnormally; however, at present, no proper adjusting tool exists, manual stepwise adjustment is only needed, the adjustment is troublesome, and the adjustment time is long.
Disclosure of Invention
In order to solve the problems of synchronous adjustment of two eccentric bearings of the conventional commercial vehicle steering gear for realizing the output of the gear ratio, the invention provides a synchronous adjustment mechanism for the eccentric bearings of the steering gear, which has the advantages of simple structure and convenience in operation, realizes the synchronous adjustment of the eccentric bearings and improves the adjustment efficiency.
Therefore, the technical scheme of the invention is as follows: synchronous guiding mechanism of steering gear eccentric bearing, including removing cover, removal axle, left adjustment arm, right adjustment arm, its characterized in that: the moving shaft is inserted into the moving sleeve from the right end and is in sliding fit with the moving sleeve, a circumferential positioning key device is arranged between the moving shaft and the moving sleeve, a first radial locking hole and a second radial locking hole are respectively formed in the moving sleeve and the moving shaft, and a gradually-tightened wedge block is inserted into the first radial locking hole and the second radial locking hole;
the left adjusting arm is fixedly connected to the left end of the movable sleeve, the right adjusting arm is fixedly connected to the right end of the movable shaft, and the left adjusting arm and the right adjusting arm are fixedly provided with positioning clamping pins.
The technical scheme is further limited as follows: a fixed connection structure of a left adjusting arm on a moving sleeve: a second positioning key is fixed on the excircle of the moving sleeve through a second screw, the left adjusting arm is sleeved on the excircle of the moving sleeve through an inner hole, and a key groove is formed in the inner hole of the left adjusting arm; the second positioning key is matched with the key groove and locked by the first locking nut; likewise, a non-fixed connection of the right adjusting arm to the moving sleeve is the same as a fixed connection of the adjusting arm to the moving sleeve. Such a fixing structure is easy to implement.
The invention has the beneficial effects that: when the device is used, the gradually-tightened wedge block is firstly taken down, the positioning clamping pins on the left side and the right side are clamped into two adjusting holes of the eccentric bearing, the gradually-tightened wedge block is inserted, the moving sleeve and the moving shaft are inwards tightened, the moving sleeve and the moving shaft are held by hands, the whole body rotates, the synchronous rotation of the eccentric bearings on the two sides is ensured, and the adjustment can be completed when the eccentric bearings are completely attached; by adopting the invention, the synchronous adjustment of the two eccentric bearings of the steering gear can be realized quickly, the adjustment is quick, convenient and reliable, and the adjustment efficiency is improved; the invention has simple structure and easy implementation.
