Multifunctional wet brake for forkman driving bridge

Abstract

The invention relates to a multifunctional wet brake for a forkman driving bridge. The inner side of a left shell of the brake is provided with an isolating ring, and a driving brake piston is positioned at the inner side of the isolating ring and is fixedly connected with the left shell by a bolt of a return spring; a parking brake piston is sheathed at the outer side of the isolating ring, compression springs of the parking brake piston are evenly distributed inside a right shell, and the outer end surface along the axial direction of the compression springs is contacted with a parking diaphragm plate; the inner side of the right shell is provided with more than two grooves along the radial direction, and the parking diaphragm plate and the circumference of the diaphragm plate are respectively and correspondingly provided with more than two convex blocks which are correspondingly positioned inside the two grooves of the right shell; the outer side of the left shell that is corresponding to the driving brake piston and the parking brake piston are respectively provided with an air bleed screw and a brake steel tube interface along the axial direction. The invention has compact structure and easy assembly; a brake steel tube and the air bleed screw are arranged on the side of the brake, so as to not interfere a charging connector; the operation is labor-saving; and the return spring has good return effect and short response time.

Description

technical field [0001] The invention relates to a multifunctional wet brake for a drive axle of a forklift. Background technique [0002] Although the current multi-functional wet brakes can be used for both driving and parking braking, the layout is relatively loose and the size is relatively large; both the air release screw and the brake steel pipe are drawn from the top of the brake, resulting in an increase in the radial size, especially The parking brake steel pipe is led out from the upper side of the brake, which is easy to interfere with the tire inflation nozzle; the outer arrangement of the driving return spring increases the radial size of the brake, and at the same time, the driving spacer is pushed to return the driving brake piston. The effect is not good, and the response time is long; the spacer is connected and fixed with the brake housing through the positioning pin; the hand brake release bolt pulls the spacer through two bolts, which is easy to cause loc...
