Problems solved by technology

[0005] However, since the working mode of the wet brake is friction braking, the friction lining is worn during the working process. When the friction lining is worn, the stroke of the brake piston increases. In o

Example Embodiment

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] The core of the present invention is to provide a hydraulic gap self-adjusting mechanism, which can adjust the amount of hydraulic oil entering the brake when it is applied between the brake and the brake master cylinder, and compensate the wear gap of the brake, so as to act as the brake friction plate After wear, the brake has the same braking effect every time the worker steps on the same braking position. Another core of the p...

Abstract

The invention discloses a hydraulic clearance self-adjusting mechanism which comprises a shell, a piston, a first one-way valve and a reset spring. One side of the piston and the shell form a first cavity, the other side of the piston and the shell form a second cavity, and the shell is provided with an oil inlet used for enabling the first cavity to communicate with a brake master cylinder and anoil outlet used for enabling the second cavity to communicate with a brake. When the piston moves from an initial position to a closed position, the volume change amount of the second cavity is equalto the oil amount required by braking when a friction plate of the brake is not worn. The first one-way valve is used for being started when the piston moves to the closed position. The reset springis arranged in the shell and used for driving the piston to reset. When the hydraulic clearance self-adjusting mechanism is applied between the brake and the brake master cylinder, the oil amount of hydraulic oil entering the brake can be adjusted, the wear gap of the brake is compensated, and the braking effect of the brake is kept when the travel of a brake pedal is not changed. The invention further discloses a forklift brake system comprising the hydraulic clearance self-adjusting mechanism.

Description

technical field [0001] The invention relates to the technical field of braking devices, and more specifically, to a hydraulic clearance self-adjusting mechanism. In addition, the present invention also relates to a forklift braking system comprising the above-mentioned hydraulic clearance self-adjusting mechanism. Background technique [0002] In vehicle braking systems such as forklifts, wet brakes are widely used. [0003] The wet brakes in the prior art are usually directly connected to the brake master cylinder, that is, when the staff steps on the brake, the brake master cylinder generates hydraulic pressure to push the brake piston to move, so that the brake friction plate and the brake disc are compressed, thereby Obtain the friction resistance torque to realize braking. [0004] It can be understood that the brake of the forklift relies on the brake master cylinder to generate hydraulic brakes. When the staff brakes, they step on the brake pedal, step on the brake ...
