Problems solved by technology

However, agricultural tractors are often driven in fields or on country roads, so an excessively large turning radius has a great adverse effect on actual driving.
[0004] In addition, there are many types of tractor engines on the market, and their length and width dimensions, structures, and installation locations are not uniform. The tractor chassis with an integrated design will be difficult to achieve standardization, generalization, and serialization due to different engines. The expansion of production scale and the reduction of manufacturing costs have caused adverse effects

Embodiment Construction

[0027] The preferred specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0028] An articulated tractor chassis such as figure 1 and figure 2 As shown, it includes a front axle 7 and a rear axle 2 for installing wheel axles. The front axle 7 is fixedly connected with the front axle supporting bracket 6, and the rear axle 2 is fixedly connected with the rear axle suspension bracket 3. Between the front axle support bracket 6 and the rear axle suspension bracket 3 is a double-layer hinged connection arranged up and down, that is, the hinged connection is realized by two hinged brackets 4 arranged up and down, and the hinged parts of the two hinged brackets 4 are in the same vertical direction. axis. The left and right sides of the hinged part of the front axle support bracket 6 a...

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 [0001] The invention relates to a tractor chassis, in particular to an articulated tractor chassis. Background technique [0002] Large and medium-sized agricultural tractors generally adopt a front-wheel drive four-wheel tractor head, and the chassis of this tractor head generally adopts an integrated structural design. This chassis has a front axle for installing the front axle and a rear axle for installing the rear axle, and the front axle and the rear axle are connected by an integral support bracket (or called a suspension bracket). The tractor's engine, gearbox, etc. are arranged on the support bracket at the position of the front axle, so as to drive the tractor through the front wheels. The support bracket at the rear axle is generally used to connect the body of the tractor or agricultural implements. [0003] This one-piece tractor chassis requires a larger turning radius when the tractor is turning, and this is more obvious on larger tractors. ...
