Abstract

The invention discloses a displacement compensator, which relates to the technical field of engineering machinery manufacturing; it includes a first oil cylinder, a second oil cylinder, a first check valve and a second check valve; the spring chamber of the first oil cylinder, the The spring chamber of the second oil cylinder and the first one-way valve imported oil and the second check valve's imported oil All communicate with the oil outlet of the brake valve; the non-spring chamber of the first oil cylinder, the non-spring chamber of the second oil cylinder and the non-spring chamber of the first one-way valve Oil outlet and the second check valve's Oil outlet Both are connected with the brake oil cylinder port of the wet brake. The invention can solve the problems of slow response and poor braking sensitivity of the construction machinery braking system.

Description

Technical field [0001] The invention involves the field of construction machinery manufacturing technology; especially a displacement compensator with displacement compensation function and used for construction machinery braking systems. Background technique [0002] The existing construction machinery wet bridge braker has a large displacement, but it is not equipped with a displacement compensator. Therefore, the response is slow during braking, and a larger storage device is required.Especially after the friction piece is worn, the displacement is several times before wearing. In this case, it is slower when making braking, and the number of brakes after the engine is turned off is greatly reduced. Invention content [0003] The purpose of the present invention is to provide a displacement compensator, which can solve the problem of slow response and poor braking sensitivity when braking system braking. [0004] In order to solve the above problems, the technical solution ad...
