Abstract
The invention discloses a hinged type tractor chassis, comprising a front axle and a back axle, wherein the front axle is fixedly connected with a front axle supporting bracket, the back axle is fixedly connected with a back axle suspending bracket, and the front axle supporting bracket and the back axle suspending bracket are connected in a hinged manner. Furthermore, the front axle supporting bracket and the back axle suspending bracket are connected in the hinged manner through an upper hinge bracket and a lower hinge bracket, and the hinged parts of the two hinge brackets are coaxial in a vertical direction. The hinged type tractor chassis is narrower in wheel track and small in turning radius and can enable large-medium tractors to better adapt to agricultural fields.
Description
Technical field
The present invention relates to a kind of tractor chassis, particularly a kind of frame-steered tractor chassis.
Background technology
Big-and-middle-sized farm tractor generally all adopts the four-wheel-type trac. headstock of f-w-d, and the structure design of integral type is generally adopted on the chassis of this trac. headstock.Have on this chassis for the propons that front wheel spindle is installed with for the back axle that hind axle is installed, adopt the supporting bracket (or being called suspension holdfast) of integral type to be connected between propons and the back axle.The driving engine of trac., change speed gear box etc. are arranged on the supporting bracket of propons position, so that by the f-w-d trac..The supporting bracket of back axle position generally is used in the wagon box that connects trac. or agricultural machinery and implement etc.
The tractor chassis of this integral type needs bigger turn radius when trac. is turned, on more big trac., this situation is just more obvious.And agricultural trac. all right sailing on field or country lane often, therefore excessive Turning radius has very big adverse effect to actual travel.
In addition, tractor engine model on the market is various, its length and width size, structure and installation site etc. are disunity all, adopt the tractor chassis of integral type design to be difficult to realize normalisation, universalization and seriation because of the difference of driving engine, and then the reduction of the production-scale expansion of trac. and manufacturing cost is caused adverse effect.
Summary of the invention
The present invention is in order to overcome above-mentioned defective of the prior art, a kind of frame-steered tractor chassis to be provided, and its wheelspan is narrower and Turning radius is little, can make large and middle tractor more adapt to agricultural place.
For achieving the above object, the present invention discloses following technical scheme:
A kind of frame-steered tractor chassis comprises propons and back axle, is fixedly connected with the propons supporting bracket on the described propons, is fixedly connected with the back axle suspension holdfast on the described back axle, and is articulated and connected between described propons supporting bracket and the described back axle suspension holdfast.
Further, realize being articulated and connected by two articulated stands of upper and lower settings between described propons supporting bracket and the described back axle suspension holdfast, and the hinge point of these two articulated stands is coaxial at vertical direction.
Further, the hinge point left and right sides of described propons supporting bracket and described back axle suspension holdfast is symmetrically arranged with hydraulic steering cylinder, and the cylinder body of described hydraulic steering cylinder is connected described propons supporting bracket and described back axle suspension holdfast respectively with piston.
Further, described propons supporting bracket is provided with engine bin, and this engine bin is provided with detouchable storehouse cover.
Further, the termination, both sides of described propons and described back axle is equipped with the mounting hole flange.
Further, at least one in described propons and the described back axle is provided with the main bag that slows down.
Further, described propons has been connected braking mechanism with at least one mounting hole flange in its both sides in the described back axle.
Further, described propons has been connected the hub reduction bag with at least one mounting hole flange in its both sides in the described back axle.
Further, also be connected with the farm implements lift system on the described back axle suspension holdfast, it comprises that an end is hinged on connecting rod and the hydraulic actuating cylinder that this connecting rod of control promotes and falls on the described back axle suspension holdfast, the cylinder body of this hydraulic actuating cylinder is connected with described back axle suspension holdfast, and piston rod is connected with described connecting rod.
Compared with prior art, the present invention has following beneficial effect:
1, adopt articulated manner to connect between propons supporting bracket and the back axle suspension holdfast, thereby make tractor chassis when turning to, have higher alerting ability and littler Turning radius, can when design, adopt narrower wheelspan, landform and the road conditions that can adapt to the rural area well, especially bilevel dual articulated structure design can greatly improve hinged intensity and reliability, has very outstanding practicality in the place of rural area complexity and road environment;
2, the symmetrically arranged hydraulic steering cylinder in the hinge point left and right sides of propons supporting bracket and back axle suspension holdfast can make the chassis operate steadily in steering procedure, can also reduce the vibrations that hinge point is subjected to, help to improve running stability and the chassis life-span of trac.;
3, the mounting hole flange that arranges on propons and/or the back axle is convenient to connect parts such as wheel, braking mechanism and hub reduction bag, not only makes loading and unloading become simple, can also improve the functional reliability of connecting portion, improves the stressed distribution character of connecting portion;
4, the main bag that slows down is used for providing deceleration in the transmission of torque of driving engine output during to the wheel shaft of front and back wheel, thereby makes operating steadily of trac.;
5, can a plurality of installing components be set within it according to different engine structures and characteristic in the engine bin, install thereby make the chassis can adapt to different driving engines; Engine bin is provided with detachable storehouse cover, when needs replacing or service engine, open the storehouse cover and just can directly from engine bin, pull down driving engine, avoided the dismounting miscellaneous part, can greatly improve maintenance efficiency, the unnecessary maintenance risk of avoiding the dismounting miscellaneous part to bring simultaneously;
6, by the connecting rod on the farm implements lift system, can make things convenient for being connected of trac. and other agricultural machinery and implement, and the hydraulic actuating cylinder on it both can control link height in order to be connected with different agricultural machinery and implement, can also drive the agricultural machinery and implement lifting that connects on it by connecting rod, thereby satisfy the requirement of different use occasions.
