Abstract
The utility model discloses a steering brake clutch for a bulldozer. According to the steering brake clutch for the bulldozer, a plurality of friction sheets are engaged at the periphery of a drive wheel by a gear; polished sheets arranged at intervals from the friction sheets are engaged at the periphery of the drive wheel; the friction sheets and the polished sheets form a friction sheet pair; a piston is pressed at the outer end of the friction sheet pair; a disc spring is arranged between the piston and a driven wheel at the outer side; pin shafts arranged on the driven wheel are provided, and penetrate in through holes in the outer side portions of the circumferences of the polished sheets; elastic washers are installed among the polished sheets, and sleeve the pin shafts. According to the steering brake clutch for the bulldozer, the polished sheets are connected with the driven wheel in a pin shaft-type connection mode, thus simplifying the connection structure, and avoiding the defects of poor manufacturability, difficult manufacturing and high machining cost generated by adopting a gear ring structure for the driven wheel; the friction sheets and the polished sheets are separated by the elastic washers strung on cylindrical pins, thus improving stress uniformity, and increasing elasticity, and then enabling the separation between the friction sheets and the polished sheets to be more rapid and thorough.
Description
Technical field
The utility model relates to clutch, especially a kind of bulldozer steering brake clutch.
Background technique
At present, domestic bulldozer steering brake system adopts wet type, multidisc, friction clutch structure more.This clutch generally comprises driving gear, friction plate, mating plate, driven gear, piston, wavy spring etc.Driving gear and friction plate engagement, mating plate and driven gear engagement.During work, under the active force of spring, compression piston makes friction plate and mating plate laminating, by frictional force, drives outer gear piece to rotate, thereby drives the driven gear being engaged with to rotate, and power is down transmitted; When separated, by hydraulic oil, piston is backed down, under the active force of wavy spring, make friction plate separated with outer gear piece.For larger-size clutch, gear ring size as driven wheel is larger, for large scale gear ring, exist technology capability bad, manufacture difficulty, the problems such as processing cost height, and between mating plate, adopt wavy spring separation also to have junction plane discontinuity, the problem that friction plate and mating plate separating rate are slow.
Summary of the invention
The purpose of this utility model is to provide a kind of bulldozer steering brake clutch, solves original clutch and manufactures the slow problem of difficulty, friction plate and mating plate separating rate.
The purpose of this utility model realizes as follows: driving wheel periphery meshes some friction plates by gear, driving wheel periphery has and the spaced apart mating plate of friction plate, it is secondary that friction plate and mating plate form friction plate, the outer end of friction plate pair is pressed with piston, between piston and outside driven wheel, dish spring is set, has the bearing pin being arranged on driven wheel, bearing pin penetrates in the through hole of mating plate periphery portion, elastic washer is housed between mating plate, and elastic washer is enclosed within on bearing pin.In clutch, between mating plate and driven wheel, adopt bearing pin Placement, clutch in conjunction with time, power is delivered to mating plate through friction plate, then by bearing pin, is delivered to driven wheel.When clutch unclamps, by the elastic washer of installing between mating plate, make friction plate and mating plate rapidly, thoroughly separated.
The utility model adopts pin axle type Placement to connect mating plate and driven wheel, has simplified linkage structure, the shortcoming that avoided driven wheel to adopt the manufacturability of gear ring structure generation bad, to manufacture difficulty, processing cost is high; Adopt the separated friction plate of the elastic washer of string on straight pin and mating plate, improved stressed uniformity, increased elastic force, make friction plate separated with mating plate more rapidly, thoroughly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, driving wheel 1 periphery meshes some friction plates 2 by gear, driving wheel 1 periphery has and the spaced apart mating plate 3 of friction plate 2, friction plate 2 forms friction plate pair with mating plate 3, and the outer end of friction plate pair is pressed with piston 6, between piston 6 and outside driven wheel 8, dish spring 7 is set, there is the bearing pin 5 being arranged on driven wheel 8, bearing pin 5 penetrates in the through hole of mating plate 3 periphery portions, and elastic washer 4 is housed between mating plate 3, and elastic washer 4 is enclosed within on bearing pin 5.During work, under the effect of dish spring 7, clamping piston 6, make friction plate 2 and mating plate 3 laminatings, the power that transmission system transmits passes on driving wheel 1, and driving wheel 1 meshes by gear with friction plate 2, by transmission of power to friction plate 2, under frictional force effect, friction plate 2 drives mating plate 3 to rotate, mating plate 3 is connected with driven wheel 8 by bearing pin 5, thereby drives driven wheel 8 to rotate, by power going down.When separated, under action of hydraulic force, push piston 6 open, under elastic washer 4 effects, make mating plate 3 and friction plate 2 rapidly, thoroughly separated.
Claims (1)
