Abstract

Master pin adjusting-free device for steering driving axle is composed of an upper master pin, a lower master pin, a bolt, an oil cup, a dish spring, a sliding bearing, a bridge shell, an oscillating bearing, a dust helmet and a steering knuckle. The bridge shell is pressed tightly on the steering knuckle which comprises the upper master pin and the lower master pin through the sliding bearing and a knuckle, the dish spring is arranged between the bridge shell and the upper master pin, an axial gap is eliminated through utilizing pre-tightening force when the dish spring is assembled, the bearing reliability of a steering driving axle is guaranteed, simultaneously, the dish spring reduces damages of impact load to the steering drive bridge as a cushioning link, and the reliability and the service life are improved.

Description

Steering drive axle is exempted from setting device with stub
(1) technical field:
The utility model belongs to the vehicle bridge field, relates to a kind of steering drive axle and exempts from setting device with stub.
(2) background technology:
At present, in the axle components of domestic trac. and construction machinery and equipment, steering drive axle wheel limit rotatable parts are realized turning to by rotating around upper and lower stub, its structure is to utilize upper and lower stub by a pair of oscillating bearing bearing load that is installed on the drive axle housing, but endplay can't be eliminated, and the general method that increases bearing cap shim that adopts is eliminated the gap, makes bearing working reliable, otherwise can accelerate the wearing and tearing and the destruction of bearing, also can produce and impact axle housing.But make when assembling in this way, need adjust by the quantity that increases, subtracts bearing cap shim according to the processing situation of actual part, and also need to readjust after using wearing and tearing, assembly difficulty is big, the inconvenience maintenance.This structure also needs to use bearing in pairs, be rigidly connected simultaneously, does not cushion link, makes the axle housing of steering drive axle bear bigger impact load and vibration, and the life-span reduces.
(3) summary of the invention:
The purpose of this utility model be to provide a kind of good reliability, simple in structure, cost is lower, use is easy to maintenance, the device of the steering drive axle stub that avoids adjusting.
The technical solution of the utility model is: the device of the steering drive axle stub that avoids adjusting comprises: go up stub 1, bolt 2, lubricating cup 4,11, axle housing 7, oscillating bearing 8, dust boot 9, following stub 10, steering swivel 13.The last stub 1 that is provided with oil leab 3 is affixed by bolt 2 and steering swivel 13; Plain bearing 6 places in the axle housing 7; Dish spring 5 places on the axle housing 7, and last stub 1 passes dish spring 5 by steering swivel 13 and places in the plain bearing 6.The following stub 10 that is provided with oil leab 12 is affixed by bolt 2 and steering swivel 13; Oscillating bearing 8 places in the axle housing 7, and dust boot 9 is installed in down between stub 10 and the axle housing 7, and following stub 10 passes dust boot 9 and places in the oscillating bearing 8, and lubricating cup 4 places in the stub 1, and lubricating cup 11 places down in the stub 10.
The beneficial effects of the utility model are: the predetermincd tension that the technical program is ingenious when having utilized the assembling of dish spring, eliminate endplay, guaranteed that by dish spring, plain bearing, oscillating bearing steering drive axle reliably carries, reduced the damage of impact load to steering drive axle, can effectively reduce the complexity that the assembling of drive axle steering yoke bolt structure is adjusted, cost-cutting has improved reliability and service life.
(4) description of drawings:
Fig. 1 exempts from the setting device structural representation for the utility model steering drive axle with stub
(5) specific embodiment:
As shown in Figure 1, steering drive axle is exempted from setting device with stub and is comprised: go up stub 1, bolt 2, lubricating cup 4,11, axle housing 7, oscillating bearing 8, dust boot 9, following stub 10, steering swivel 13.
Plain bearing 6 places in the axle housing 7, and dish spring 5 places on the axle housing 7, and the last stub 1 that is provided with oil leab 3 passes dish spring 5 by steering swivel 13 and places in the plain bearing 6, and last stub 1 is affixed by bolt 2 and steering swivel 13; Oscillating bearing 8 places in the axle housing 7, and dust boot 9 is installed in down between stub 10 and the axle housing 7, and following stub 10 passes dust boot 9 and places in the oscillating bearing 8, and the following stub 10 that is provided with oil leab 12 is affixed by bolt 2 and steering swivel 13.
Owing to compressed dish spring 5 during assembling, endplay is eliminated in the existence of dish spring 5 predetermincd tensions, thereby does not need to adjust the needs that can satisfy carrying.When vehicle travels under good road conditions, the load that steering drive axle is subjected to is passed to steering swivel 13 and following stub 10 by axle housing 7, oscillating bearing 8, is born by tire, but when under vehicle is jolting road conditions, travelling, steering drive axle tire meeting built on stilts, its load can be passed to axle housing 7 by steering swivel 13 and last stub 1 behind dish spring 5, because the dish spring has been eliminated endplay, just can not produce and impact axle housing, as a buffering link, reduce vibration simultaneously, improve the life-span of steering drive axle.
Lubricating cup 4 places in the stub 1, and lubricating cup 11 places down in the stub 10.Regularly in lubricating cup 4 and 11, inject butter and realize plain bearing 6 and oscillating bearing 8 lubricated maintenances.The safeguard function that dust boot 9 is realized oscillating bearing 8.
