Abstract
The invention discloses a driving front axle for a wheel type mini-excavator, which relates to an excavator mechanism. The driving front axle comprises an axle body, a steering knuckle, a wheel hub, a steering oil cylinder, balance oil cylinders, and a supporting base, and is characterized in that the axle body consists of a speed-down assembly, an axle shell, and a universal joint consisting of two semiaxles and two pins in the steering knuckle; the two balance oil cylinders are fixed on a chassis directly, the middle part of the axle body is provided with the supporting base, and a horizontal shaft is fixed on and extends from the chassis to be sleeved into a supporting base hole in movable fit directly. The driving front axle has the advantages that the front axle of the mini-excavator adopts the driving front axle, the structure is to combine the driving front axle of a vehicle with the front axle of the prior mini-excavator, reasonably simplify the structure, remove the prior cross beam of the mini-excavator, connect the upper side of the balance oil cylinder and the chassis directly, arrange the supporting base on the axle body directly, so that the overall gravity center is lowered, and the stability is good. The driving front axle for the wheel type mini-excavator can run freely on a construction site with worse geological condition.
Description
Technical field:
The present invention relates to excavating machine mechanism.
Background technology:
Bridge construction is the pontic of girder structure before the small-sized wheeled digger at present, steering swivel, wheel hub, turn to oil cylinder, balancing cylinder, the crossbeam of two balancing cylinder upper fixed, supporting base in the middle of the crossbeam is formed, pontic cast steel forms, play with the chassis and be connected supporting role, the chassis has be connected supporting at 2 with driving rear axle, with propons be single point supporting, single point supporting is by fixing one being inserted in the crossbeam middle part with the horizontal shaft running-fit and going up and extend a fixing supporting base hole seat and realize on the chassis, thereby make chassis and front and back bridge form the plane three point support, this top, pontic both sides is provided with two balancing cylinder support platforms, these two platform upper fixed have two balancing cylinders, damping and shock damping action have been played, the pontic both sides are equipped with steering swivel, wheel hub, because the excavating machine operating mode is poor, so steering power can not use the bearing circle rotary machine drive mechanism of car drive front axle, rotate to reach and turn to purpose but promote U type joint shell, turn to required bigger propelling thrust because have only hydraulic coupling to satisfy with oil cylinder.
Because the excavating machine operating mode is poor, is different from automobile and travels on highway, front-wheel is operation on the unfairness building site, the building site geological state may be a mud, and sandy soil class weak soil geology is skidded so front-wheel usually is absorbed in soft melt pit, can't advance or retreat, must could break away from on-the-spot with outer power traction.The propons driving problems causes us and considers, but can not directly use car drive front axle, the universal-joint that car drive front axle is made of the Double half axle double-pin in deceleration assembly, axle housing, the steering swivel, braking hub, intermediate rod are formed, it does not have the supporting-point of excavating machine propons, two side platforms on its propons are to be connected with spring plate, therefore can not former state apply mechanically.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, provide a kind of wheel shovel to drive propons.
The solution of the present invention is: comprise pontic, steering swivel, wheel hub, turn to oil cylinder, balancing cylinder, supporting base form, it is characterized in that pontic is that the universal-joint that the Double half axle double-pin in deceleration assembly, axle housing, the steering swivel constitutes is formed, two balancing cylinders directly are fixed on the chassis, the pontic middle part is provided with supporting base, extends the direct running-fit of horizontal shaft on the chassis and is inserted in the supporting base hole.
Advantage of the present invention is: the mini-excavator propons adopts and drives propons, structure is that car drive front axle is combined and simplification rationally with present mini-excavator propons, the present crossbeam of deletion mini-excavator, the balancing cylinder top directly is connected with the chassis, supporting seat is set directly on the pontic, whole center of gravity descends good stability.Can move freely in the building site that geological state is relatively poor.
Description of drawings:
Fig. 1 is a structural scheme of mechanism of the present invention.
Fig. 2 is a drive mechanism scheme drawing of the present invention.
The specific embodiment:
Structure of the present invention is: comprise pontic, steering swivel, wheel hub, turn to oil cylinder (11), balancing cylinder, supporting base form, it is characterized in that pontic is that the universal-joint (6) that the Double half axle double-pin in deceleration assembly (1), axle housing (2), the steering swivel constitutes is formed, two balancing cylinders directly are fixed on the chassis, the pontic middle part is provided with supporting base, extends the direct running-fit of horizontal shaft on the chassis and is inserted in supporting base hole (12).
The body skin of deceleration assembly, axle housing are that cast steel forms.The body skin of deceleration assembly (1), axle housing also can be the steel plate conjoined structures that steel plate then is welded through punching press, and axle housing (2) forms with the axle housing flange welding disjunctor of steel car system.Steering swivel is by U type joint shell (5) and supporting base (4) bearing pin connection structure, supporting base (4) is fixed on the axle housing flange, U type mouth outwardly, joint shell (5) is fixed on the wheel hub central siphon (10), U type mouth inwardly, two U type mouths connect using bearing pin, and universal-joint (6) structure also is a Double half axle bearing pin running-fit connection structure.
The body skin of deceleration assembly (1), the rounded opening of its front end face, this circular open has annular flange.This annular flange and deceleration assembly (1) bolt together, deceleration assembly (1) is installed in it.
Deceleration assembly (1) is connected with inner shaft by the transmission shaft that is installed in the axle housing (2), inner shaft is connected with outer semiaxis by universal-joint (6) again, universal-joint is that the outer semiaxis other end of double-pin type or three pin-type structure then is connected with wheel hub central siphon (10), and deceleration assembly (1) realizes that by transmission shaft, inner shaft, bearing pin, outer semiaxis, wheel hub wheel hub drives successively.Drg (7) is installed in the brake wheel (8).
Axle housing middle part be provided with the chassis on the hole seat that is inserted in of fixing horizontal shaft running-fit.
Top, axle housing both sides respectively has a platform to be connected with balancing cylinder on the chassis.
It turns to is the U type joint shell realization that is promoted the propons both sides by the steering oil cylinder structure.
Claims (3)
1, drive front axle of small-sized wheeled digger, comprise pontic, steering swivel, wheel hub, turn to oil cylinder (11), balancing cylinder, supporting base form, it is characterized in that pontic is that the universal-joint (6) that the Double half axle double-pin in deceleration assembly (1), axle housing (2), the steering swivel constitutes is formed, two balancing cylinders directly are fixed on the chassis, the pontic middle part is provided with supporting base, extends the direct running-fit of horizontal shaft on the chassis and is inserted in supporting base hole (12).
