Abstract
The utility model relates to a hydraulic brake clearance adjuster of a loading machine. In the brake clearance adjuster, a shell (5) is fixed on a middle connector (6) by a bolt (10); a spring (4) is fixed on the middle connector (6); a piston (3) is connected with the spring (4); the spring (4) and the piston (3) moves in the shell (5); and a one-way valve (2) is arranged in the shell (5) and is blocked with a screw plug (1). The adjuster is communicated with a drive axle brake piston (8) by a pipeline (7) to form a closed oil cavity. The adjuster leads hydraulic brake to have a fixed time delay, is arranged in a pipeline between a brake valve and a drive axle, and is low in cost and convenient in installation.
Description
Technical field
The utility model relates to a kind of loader hydraulic braking clearance adjuster.
Background technique
At present, loader hydraulic braking mode majority is: when the loader driving needs braking, step on the moving pedal of brake valve braking, high pressure oil exports the brake piston that directly leads in the forward and backward ransaxle by brake valve, brake piston promotes wearing piece, make the wearing piece locking, braked, the parking of driving a vehicle.Because the loader braking is very frequent, in the process of using, the ransaxle braking frictional plate often is worn, and wearing piece wearing and tearing back brake piston stroke increases, and the brake latency time increases, and braking can not keep a regular time to postpone in this system.
Summary of the invention
Make period of braking postpone the problem that increases in the existing loader hydraulic braking after the wearing and tearing of ransaxle braking frictional plate in order to overcome.The invention provides a kind of loader hydraulic braking clearance adjuster, this regulator makes the stroke L of ransaxle brake piston be determined by the oil mass of the stroke S of brake clearance regulator, regulator communicates with the ransaxle brake piston by pipeline, and forms an airtight oil pocket.After the wearing and tearing of ransaxle braking frictional plate, the stroke L of ransaxle brake piston increases, the required oil mass of stroke S of brake clearance regulator also increases, it is big that airtight oil pocket volume becomes, the pressure step-down, brake the one-way valve that fluid opens in the regulator and enter into the piston right side this moment, replenishes the fluid that is lacked.Make the brake latency time constant like this, can provide a regular time to postpone.When the pressure of the oil that flows out when brake valve surpasses the pressure of its setting, one-way valve opens in the regulator, pressure oil is used as braking force.This regulator is installed in the pipeline between brake valve and the ransaxle, and cost is low, and is easy for installation.
The technological scheme that its technical problem that solves the utility model adopts is: in this brake clearance regulator, housing is by being bolted on the intermediate connector, spring is fixed on the intermediate connector, piston is connected with spring, spring and piston move in enclosure interior, one-way valve is installed in enclosure interior, and blocks with plug screw.
In this regulator, housing is by being bolted on the intermediate connector, and spring is fixed on the intermediate connector, and piston is connected with spring, piston side-to-side movement in the stroke S scope that enclosure interior is set, and one-way valve is installed in enclosure interior, and blocks with plug screw.Regulator communicates with the ransaxle brake piston by pipeline, and forms an airtight oil pocket.Retardation pressure oil enters the brake clearance regulator from the A mouth, flows in the direction of arrows, and one the road to piston spring chamber side, also enters into the left side of one-way valve simultaneously.After the wearing and tearing of ransaxle braking frictional plate, it is big that airtight oil pocket volume becomes, the pressure step-down, and the one-way valve that braking fluid is opened in the regulator enters into airtight oil pocket, replenishes the fluid that is lacked, and makes the brake latency time constant.
