Abstract
The utility model relates to a main hydraulic controlling clutch for a bull dozer, which is characterized in that a shaft coupling is connected with the shaft of an outer spline; the shaft is arranged on the casing via a bearing; the other end of the shaft is connected with a connecting plate; a cylinder is arranged on the bearing housing of the gearbox; a piston is arranged at the front part of the cylinder; the cylinder is sealed via a sealing ring and a cavity is formed between the piston and the cylinder; the cavity is communicated with the oil channel of the cylinder; the oil channel is communicated with the inlet and the outlet of a control valve; the other end of the connecting plate is connected with the cylinder and the piston via a dowel pin; a reset spring is arranged between the piston and the connecting plate; the output gear with a plurality of external gears is connected with the power input shaft of gearbox via the spline; a plurality of friction disks are fixed on the external gears of the output gear in a circumferential direction; a plurality of padding plates are arranged between the friction disks at intervals; the connecting plate is mounted on the output gear via the bearing. The utility model has the advantages of guaranteeing smooth joint and complete separation within a short period, simple structure, long service life, weak impulsive force of combination, no need of maintenance and adjustment as well as portable operation.
Description
Technical field:
The utility model relates to a kind of mechanical type bulldozer hydraulic control main clutch, is connected between motor and the gearbox, transmits or cut off the power transmission between the two.
Background technique:
The mechanical type crawler dozer generally adopts the hydraulic booster wet friction clutch at present, uses the toggle hinge bar and uses centrifugal force, applies sufficient pressure to platen, and hinge bar contact contact platen is easy to wear, complex structure, and work has noise.And along with the driven friction disc wear of active, impacting force will reduce sharp, produces serious skidding to cause clutch, in order in use to keep necessary impacting force, must adjust, and has increased the complexity of safeguarding.
Summary of the invention:
The purpose of this utility model provides a kind of bulldozer hydraulic control main clutch, and the impacting force of friction plate necessity is avoided adjusting in guaranteeing to use, and reduces and safeguards.
The purpose of this utility model realizes as follows: this bulldozer hydraulic control main clutch, relate to housing, shaft coupling, axle, land, friction plate, backing plate, output gear, return spring, the gearbox input shaft, the shaft coupling that is connected with engine power is connected with the axle of band external splines, the axle by Bearing Installation on housing, the axle the other end is connected with land, pass through the Bearing Installation cylinder body on the gear-box axle bearing, there is piston the cylinder body front portion, piston and cylinder body form cavity by the sealing of seal ring, this cavity communicates with the oil duct of cylinder body, this oil duct is imported and exported with control valve and is communicated, the land the other end and cylinder body, piston links together by pin, between piston and the land return spring is arranged, the output gear of band external tooth is connected by spline with the gearbox power input shaft, circumferential fixed friction sheet on the external tooth of output gear is separated with backing plate between the friction plate, land by Bearing Installation on output gear.
Its integral installation is in mechanical type bulldozer transfer case housing inside.
The utility model utilizes control valve to control the flow direction and the pressure of hydraulic oil, separates under hydraulic oil and return spring comprehensive function and engages.The combination of main clutch: when the main clutch valve is in binding site, hydraulic oil enters in the main clutch cylinder body by the oil duct of gear-box axle bearing, promote piston advances forward, overcome the spring force of return spring, eliminate the gap between land, friction plate, the backing plate, guarantee enough impacting forces, piston, output gear and land are become one.The power of motor then passes to the gearbox input shaft by shaft coupling, axle, land, piston, output gear, and power transmission is to gearbox.The separation of main clutch: when the main clutch valve when being engaged to the disengaging configuration, hydraulic fluid pressure descends in the main clutch, piston is motion backward under the spring force effect of return spring, friction plate separates with backing plate, the transmission of power of motor is given shaft coupling, axle, land, piston and cylinder body and is made its rotation, and can not be delivered on the input gear, thereby motor to the power of gearbox input shaft is cut off, for gear shift is got ready.
The utility model bulldozer hydraulic control main clutch, not only can guarantee in the short time to engage smooth-going with separate thoroughly, and simple in structure, long service life, joint impact power is little, Maintenance free and adjustment, driver's operation is light.
