Hydraulic multi-plate friction plate brake and clearance compensation device

Hydraulic multi-plate friction plate brake and clearance compensation device 7l · Qa ANZ l = 7.6553 × 105A sampan <jOasCG17.6553 × 10 a x5.3 × 106dt = 』 : '405 .96 . A ) dt <405.96 × 2.3 × 0.001 ≈ 4.94 (mm) of a known brake stroke 3.2mm, brake piston cavity cross-sectional area S = 25190mm, leakage into the brake Q Travel △ = 4.94 / S = 4.94/25190 = 0.0002 (mm). Thus, its braking effect is very small stroke , that meet the design requirements. 4 Conclusion 1) The research design in this paper for multi- chip friction plate brake hydraulic brake, it has a braking torque brake quickly, safe, reliable, compact , etc., for applications that require a large braking torque of the large heavy-duty wheel Type of construction machinery . Mount within 2】 brake films such as manufacturing errors stitch and other reasons, its thickness be biased by the Park compensation device can automatically adjust the brake piston position , do not need to be adjusted pre- set the brake stroke , greatly simplifying the brake words Whole . 3) The process of using the brake , friction wear , relying on clearance compensation, the friction disk space is always asked to keep the best space in the state of the original design can greatly reduce the wear and improve their work life. 4) to lift the brake in the braking or when braking , no matter the size or thickness deviation friction plate friction plate wear the number , by the role of compensation device , or release the brake to brake the same itinerary , ensuring a constant braking time and braking rapidly Safe and reliable . 5) From a comprehensive point of view, research design in this paper Pina drive , excellent performance is a new type of brake. This subject is too technical for the state re- hsiang key components prepared eighty-five scientific and technological projects .
