Description
Technical Field
The invention relates to a synchronous adjusting mechanism for eccentric bearings of a steering gear, which enables the eccentric bearings at two ends of a rocker shaft of the steering gear to realize synchronous eccentric adjustment and improves assembly efficiency and assembly quality.
Background
At present, most of rocker shafts of commercial vehicle steering gears are of helical tooth structures, steering clearance is adjusted to be axial clearance adjustment, and when the steering gears are adjusted, the rocker shafts are axially moved forwards or backwards by means of adjusting bolts arranged in the axial position direction of the rocker shafts and threaded structures of side covers, and meshing clearance between the rocker shafts and rack piston gear pairs is controlled to achieve the purpose of adjustment, so that mechanical clearance of the whole steering gear mechanism is controlled. The gap adjusting device of the steering gear with the structure is simple, and the gap of the gear pair can be adjusted only by using one inner hexagonal wrench, but the steering gear with the structure cannot realize the output of a speed ratio.
The commercial vehicle steering gear realizing the output of the speed ratio adopts two eccentric bearings to adjust the meshing gap between the rocker shaft and the rack piston, the whole adjustment process needs to ensure the synchronous adjustment of the two eccentric bearings, otherwise, the rocker shaft is easy to wear early in the rotation process, and oil leakage and steering clamping stagnation are caused by the damage of an oil seal; the output force of the steering gear is weakened, the aligning moment is abnormally increased, and the bearing is abnormally damaged and other faults; however, no proper adjusting tool exists at present, and the adjustment is troublesome and long only by manual step-by-step adjustment.
Disclosure of Invention
In order to solve the problem of synchronous adjustment of two eccentric bearings of the existing commercial vehicle steering gear for realizing the output of the speed ratio, the invention provides a synchronous adjustment mechanism of the eccentric bearings of the steering gear, which has the advantages of simple structure and convenient operation, realizes synchronous adjustment of the eccentric bearings and improves the adjustment efficiency.
For this purpose, the technical scheme of the invention is as follows: the synchronous adjusting mechanism of the eccentric bearing of the steering gear comprises a movable sleeve, a movable shaft, a left adjusting arm and a right adjusting arm and is characterized in that: the movable shaft is inserted into the movable sleeve from the right end for sliding fit, a circumferential positioning key device is arranged between the movable shaft and the movable sleeve, a first radial locking hole and a second radial locking hole are respectively arranged on the movable sleeve and the movable shaft, and a gradually tightening 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 positioning clamping pins are fixed on the left adjusting arm and the right adjusting arm.
Further limiting the technical scheme: the left adjusting arm is on the movable sleeve a fixed connection structure: the outer circle of the movable sleeve is fixed with a second positioning key through a second screw, the left adjusting arm is sleeved on the outer circle of the movable sleeve through an inner hole, and a key slot is arranged 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 adjustment arm to the movable sleeve is identical to a fixed connection of the adjustment arm to the movable sleeve. Such a fixing structure is easy to implement.
The beneficial effects of the invention are as follows: when the device is used, firstly, the gradually tightening wedge blocks are taken down, the positioning bayonet locks at the left side and the right side are clamped into the two adjusting holes of the eccentric bearings, the gradually tightening wedge blocks are inserted, the moving sleeve and the moving shaft are tightened inwards, the moving sleeve and the moving shaft are held by hands to integrally rotate, the eccentric bearings at the two sides are ensured to synchronously rotate, and the adjustment can be completed when the eccentric bearings are completely attached; the invention can rapidly realize synchronous adjustment of two eccentric bearings of the steering gear, and the adjustment is rapid, convenient and reliable, thereby improving the adjustment efficiency; the invention has simple structure and easy implementation.
