Summary of the invention
The utility model has overcome the deficiencies in the prior art, the driving propons that a kind of construction machinery and equipment is used has been proposed, described driving propons changes axle housing and adopts welding process, directly adopt the integral type foundry technique, do not need to weld back processing, oversimplify processing technology, thereby reduced productive costs, improved the qualification rate of product; Put on the diff and the power input right side, and design brings great convenience to complete vehicle structure like this, and the driving engine center of gravity can reduce as much as possible, uses the center of gravity of car load to reduce, and also makes things convenient for the driving parts connection and install; Adopt double acting pull bar oil cylinder to turn to, simplified structure so not only, thus also greatly change its road-holding property, install and keep in repair also more convenient and quicker; The wheel reduction gear shell directly casts out the satellite gear erecting frame, installs simple, not fragile; Adopt diesis to turn to jack shaft, transfer torque is big, and safety performance is good; Middle suspension type is installed and is simplified installation form, the convenient installation.
The technical solution of the utility model is: the driving propons that a kind of construction machinery and equipment is used, comprise wheel reduction gear, propons housing, right side in propons housing center is provided with diff, a left duplex center cross semiaxis is set on the left side of described diff, a right duplex center cross semiaxis is set on the right of described diff, both sides at the propons housing are provided with bearing hole, described bearing hole is provided with wheel limit steering swivel, the described limit steering swivel of taking turns connects mutually with wheel reduction gear, is provided with in the middle position of described propons housing and turns to oil cylinder.
Be provided with a steering ball end on the described top of the piston rod of oil cylinder that turns to.
Described steering ball end links to each other with wheel limit steering swivel by a steering track rod.
Below described diff, be provided with power input spider, be provided with power input center cross in the inside of described power input spider.
Described power input center cross is connected with described left duplex cross semiaxis through diff with a driven tooth by a driving tooth.
Described power input center cross is connected with described right duplex cross semiaxis through diff with a driven tooth by a driving tooth.
The rotational angle of wheel limit steering swivel is 45 degree.
The utlity model has following beneficial effect:
1) compact conformation, safety is good;
2) adopt double acting pull bar oil cylinder to turn to, steer ability is good;
3) easy for installation simple, the reliability height.
