Abstract
The utility model provides a turn to braking gearbox belongs to farm machinery technical field, the steering gear and the shift fork that set up in the box, its characterized in that steering gear one side sets up the braking spline housing, this braking spline housing outer loop cup joints external friction plate and inner friction piece, still be equipped with the braking seat in the box, this braking seat one side is equipped with the braking cavity, the braking cavity sets up a plurality of alternate breaker slots along its axial direction, external friction plate and inner friction piece that braking spline housing outer loop cup jointed are shen ru brakied inside the cavity, and pass through external friction plate, steering gear is brakied with the chucking locking of breaker slot to the inner friction piece. The utility model discloses increasing braking system in hand agricultural machine box, can applying the brake simultaneously or slow down when turning to, the operator of being convenient for controls turning radius, and the operation is accurate, and boost efficiency more can adapt to farm field environment complicated and changeable.
Description
Technical field
The utility model belongs to technical field of agricultural machinery, is specifically related to a kind of braking in a turn gearbox.
Background technique
China is large agricultural country, and greatly, the cultivated area as the industrial crops such as potato, great Jiang, garlic, shallot on the ground such as Shandong, Henan, Yunnan, northeast has accounted for sizable ratio for grain and victual cultivated area.And plant these industrial crops and need the support energetically of farm machinery to improve operating efficiency, particularly walking type reaping machine or tractor are widely used especially.The braking in a turn gearbox of these walk-behind type agricultural machineries existing all can not retarding braking when changing direction.During owing to turning to, the inertia of hand agricultural machinery is all very large, and bad manipulation, causes radius of turn excessive, and operating efficiency is low, and operation quality also can be subject to certain impact.
Model utility content
For problems of the prior art, the utility model object is the technological scheme providing a kind of braking in a turn gearbox.
A kind of braking in a turn gearbox, comprise the steering gear and shift fork that arrange in casing, it is characterized in that steering gear side arranges brake spline sleeve, this brake spline sleeve outer shroud socket outside friction disc and inner attrition piece, also Brake Block is provided with in casing, this Brake Block side is provided with braking cavity, braking cavity arranges some alternate breaker slots along its axial direction, outside friction disc and the inner attrition piece of the socket of brake spline sleeve outer shroud deeply brake inside cavity, and pass through the clamping locking skid steer gear of outside friction disc, inner attrition piece and breaker slot.
Described braking in a turn gearbox, it is characterized in that described outside friction disc and inner attrition piece interval are arranged, and most internal sheet is outside friction disc with most outer plate, inner attrition piece inner ring is provided with colored tooth and surface is provided with frosted material, this flower tooth and brake spline sleeve sting drive fit, be equipped with lug outside described outside friction disc, lug penetrates breaker slot, makes Brake Block engage outside friction disc.
Described braking in a turn gearbox, is characterized in that the sheet number of described spaced outside friction disc and inner attrition piece is respectively 4 and 3.
Described braking in a turn gearbox, is characterized in that described brake spline sleeve outer shroud is also socketed thrust collar, and first socket thrust collar is socketed outside friction disc and inner attrition piece again, and described shift fork pushing thrust collar is used for jam-packed outside friction disc and inner attrition piece.
Described braking in a turn gearbox, is characterized in that described steering gear is in transmission connection reduction gear.
The utility model increases braking system in walking agricultural machine casing, and can brake when turning to simultaneously or slow down, convenient operation person controls radius of turn, and operation is accurate, and raising efficiency, more can adapt to farm field conditions complicated and changeable.

In figure: 1-reduction gear, 2-shift fork, 3-outside friction disc, 31-lug, 4-inner attrition piece, 41-frosted material, 42-flower tooth, 5-casing, 6-brakes cavity, 7-Brake Block, 8-breaker slot, 9-brake spline sleeve, 10-thrust collar, 11-steering gear.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
A kind of braking in a turn gearbox, comprise the steering gear 11 and shift fork 2 that arrange in casing 5, steering gear 11 side arranges brake spline sleeve 9, this brake spline sleeve 9 outer shroud is first socketed thrust collar 10, be socketed some outside friction discs 3 and inner attrition piece 4 again, Brake Block 7 is also provided with in casing 5, this Brake Block 7 side is provided with braking cavity 6, braking cavity 6 arranges some alternate breaker slots 8 along its axial direction, and the lug 31 be equipped with outside outside friction disc 3 enters along breaker slot 8 and brakes cavity 6 inside together with inner attrition piece 4 and brake spline sleeve 9.Outside friction disc 3 and inner attrition piece 4 interval are arranged, and sheet number is preferably respectively 4 and 3, and most internal sheet and most outer plate are outside friction disc 3, i.e. outside friction disc 3 sandwiched inner attrition piece 4 between any two; Inner attrition piece 4 inner ring is provided with colored tooth 42, and surface is provided with frosted material 41, and this flower tooth 42 stings drive fit with brake spline sleeve 9.
Hand agricultural machine is when turning to, shift fork 2 can be stirred simultaneously, shift fork 2 can promote thrust collar 10, thrust collar 10 will outside friction disc 3, inner attrition piece 4 jam-packed, breaker slot 8 due to Brake Block 7 can pin the lug 31 of outside friction disc 3, outside friction disc 3 is braked, because the frosted material of inner attrition piece 4 41 and outside friction disc 3 touch to produce rub simultaneously, outside friction disc 3 will clamp braking inner attrition piece 4, inner attrition piece 4 inner ring is provided with colored tooth 42 because stung tightly brake spline sleeve 9, so just reach the effect of skid steer gear 11.Described steering gear 11 is in transmission connection reduction gear 1, so just reach this hand agricultural machine when turning to, slows down or the effect of braking simultaneously.
