Description
Technical field
The present invention relates to counterweight, specifically counterweight after a kind of wheel-tire tractor after trac..
Background technology
Along with China's country labor force transfer, Land Sizeization are managed, to as modern agriculture requisite trac. various aspects of performance, requirements at the higher level are proposed.Counterweight affects one of key that trac. power gives full play to, can improve tractor traction adhesion value, reduce drive wheel and skid, reduce trac. center-of-gravity position simultaneously, improve trac. stability; And the drive wheel rate of skidding can be dropped to rational scope by suitable counterweight, both saves fuel oil, and raises the efficiency, reduce again the wearing and tearing [1] of tire.But counterweight select the impact being subject to many factors, the excessive or too small negative effect [2] all can brought in various degree of counterweight amount.Therefore require that trac. counterweight amount can increase and decrease according to actual needs, and ensure that location is reliable, easy accessibility.The most structure of rear counterweight that current trac. uses is simply by contact surface and the Bolt to position of flat or arc, and shearing stress suffered by bolt is large, and reliability reduces; Or rear counterbalance design is labyrinth, wall thickness marked change stress is concentrated to be increased, and needs processing multiple after casting, and complex procedures cost is high.
Through retrieval, find to disclose a kind of patent No. CN200620081829, wheel type tractor rear wheel counterweight, but this counterweight location is unreliable, and not identical with technical matters to be solved in structure with the application.So do not find constructed open source literature in the art.
Summary of the invention
The object of the present invention is to provide counterweight after a kind of wheel-tire tractor, reasonable in design is simple, and location is reliable, easy accessibility, can select dress Different Weight counterweight as required, meets the different demand of actual job.
In order to reach above-mentioned purpose, present invention employs following technical scheme, counterweight after this wheel-tire tractor, comprise the first clump weight, described first clump weight has centre hole, has 8 bolt positioning holes be uniformly distributed along the circumference at central aperture edge, wherein has 2 symmetrical bolt positioning holes to be semicircle gap shape, for installing spacer, other 6 bolt positioning holes are the circular hole for hold-down bolt.
Described first clump weight lateral surface has 3 grooves be uniformly distributed along the circumference, and the circle centre position of the groove of the first clump weight is provided with tapped bore.
Described first clump weight 150kg.
Also comprise the second clump weight, described second clump weight arranged outside 6 grooves be uniformly distributed along the circumference, and wherein three groove opposites at interval are provided with projection, the groove of corresponding first clump weight of projection on the second clump weight adjacent with the first clump weight, the circle centre position of each groove of the second clump weight is also provided with knock hole.
Described second clump weight is arranged with two facets along outer circumference surface, in order to dodge tire tube valve after assembling.
The knock hole axle center of the tapped bore of the groove of described first clump weight, the groove of the second clump weight is consistent and be fixed together through location by stud, then uses nut tightening.
Described second clump weight 255kg.
Compared to prior art, the present invention has following beneficial effect:
First clump weight has 8 bolt positioning holes be uniformly distributed along the circumference near centre hole, wherein has two of symmetry for semicircle gap, for installing described spacer, increases positioning precision and intensity; Other 6 is circular hole for hold-down bolt.First clump weight has 3 grooves be uniformly distributed along the circumference, and the circle centre position of each described groove is provided with tapped bore, installs when being convenient to assembling multi-disc counterweight.Second clump weight is choosing dress parts, can not fill according to trac. actual job demand, select fill 1 to or choosing fill 2 right.Second clump weight side arranges 6 grooves be uniformly distributed along the circumference, and wherein three groove opposites at interval are provided with certain thickness projection, and the circle centre position of each described groove has bolt positioning hole.Second clump weight is arranged with two facets along outer rim, in order to dodge tire tube valve after assembling.When choosing fills the second clump weight described in a pair, three projections of described second clump weight and three groove fit of described first clump weight realize circumference and locate, and stud one end is fastened in described first clump weight tapped bore, and on the other end, jack panel is fixed; Choosing fill two to described second clump weight time, after first pair of described second clump weight coordinates with described first clump weight, second pair of described second clump weight rotates 180 ° relative to first to described second clump weight, namely second to the projection and first of described second clump weight to three groove fit of described second clump weight opposite without projection, easy to assembly and increase dynamic balance stability; The outer rim plane face of two pairs of described second clump weights overlaps, and ensures to dodge tire tube valve.。
Accompanying drawing explanation
Fig. 1 is counter weight construction schematic diagram after wheel-tire tractor of the present invention.
In figure: 1-first clump weight, 2-stud, 3-second clump weight, 4-nut, 5-spacer.
Detailed description of the invention
Detailed description for the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the present invention.
According to Fig. 1, counterweight after wheel-tire tractor, comprises the first clump weight 1, spacer, the second clump weight 3, stud and nut.First clump weight has 8 bolt positioning holes be uniformly distributed along the circumference near centre hole, wherein has two of symmetry for semicircle gap, for installing described spacer, increases positioning precision and intensity; Other 6 is circular hole for hold-down bolt.First clump weight 1 is connected on trac. wheel hub by above-mentioned knock hole bolt, nut.First clump weight has 3 grooves be uniformly distributed along the circumference, and the circle centre position of each described groove is provided with tapped bore, installs when being convenient to assembling multi-disc counterweight.
