Abstract
The utility model discloses a kind of oil gas master brake cylinder, comprise cylinder assembly and the plunger cylinder assembly that is attached thereto, cylinder assembly comprises cylinder, piston, piston rod and pull back spring, and the plunger cylinder assembly is provided with the oil-feed valve, and this valve is provided with tapered small coil springs.The utility model oil gas master brake cylinder has that good airproof performance, deceleration and stopping performance are reliable, long service life, advantage such as easy to process.
Description
Technical field the utility model relates to the oil gas master brake cylinder that uses in a kind of construction machinery and equipment, the heavy type mining brake system of car.
What employed oil gas master brake cylinder (being commonly called as assistor) adopted in the present domestic engineering truck of background technology, the heavy type mining brake system of car is that oil cylinder is a piston cylinder operator, easy hair fastener in the work, have a strong impact on deceleration and stopping performance, and an aperture that fluid infusion is used as braking liquid is arranged in the cylinder hole.In the braking procedure, this hole can produce damage to the leather cup of motion, thereby has influence on the service life of master cylinder.
Utility model content technical problem to be solved in the utility model is to propose that a kind of good airproof performance, deceleration and stopping performance are reliable, long service life, oil gas master brake cylinder easy to process.
For solving the problems of the technologies described above, the utility model oil gas master brake cylinder comprises cylinder assembly and the plunger cylinder assembly that is attached thereto, described cylinder assembly comprises cylinder, piston, piston rod and pull back spring, described plunger cylinder assembly is provided with the oil-feed valve, and this valve is provided with tapered small coil springs.
Above-mentioned oil gas master brake cylinder is respectively equipped with the guiding wear ring on described piston and the plunger cylinder.
Above-mentioned oil gas master brake cylinder, described cylinder and plunger cylinder partly adopt the extension mode to link together.
Plunger cylinder part of the present utility model has been improved sealing property owing to adopted valve oil-feed structure, has improved reliability of products and service life.Cylinder portion liner wear ring, the leak tightness and the service life of having improved seal ring greatly.Cylinder partly adopts stretching method to be connected with oil cylinder, has improved the bonded assembly reliability, is convenient to assembling again.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
Fig. 1 is the integral structure scheme drawing of the utility model oil gas master brake cylinder.
The specific embodiment as shown in the figure, the utility model oil gas master brake cylinder partly is made up of cylinder portion and plunger cylinder, both link together by stretching method.Cylinder portion comprises cylinder 4, piston 9, piston rod 7 and pull back spring 6.Be respectively equipped with guiding wear ring 8,5 on piston 9 and the plunger cylinder.Plunger cylinder partly is provided with oil-feed valve 2 and tapered pull back spring 1 (small coil springs), and piston rod 7 is simultaneously as the plunger rod of plunger cylinder part, and its outer wall is lined with plunger seal circle 3.
