Abstract
The invention provides a wet type vehicle brake braking force increasing mechanism and relates to the field of automobile brake manufacturing. A pushing piston and a spring are together mounted in a cylinder body, a spring adjusting plug is arranged at one end of the spring, a large end face of a boosting piston and the front end of the pushing piston are oppositely arranged in the cylinder body, an oil inlet connector is formed in the cylinder body and arranged between the pushing piston and the boosting piston, and the space between the pushing piston and the boosting piston is filled with hydraulic oil. A blocking ring is mounted between the peripheral face of the small end of the boosting piston and the cylinder, a brake friction piece is pressed on the small end face of the boosting piston through an end cover body, a rotary shell is mounted on a shaft through a bearing, an oil inlet connector is arranged between the boosting piston and the blocking ring, and an oil cavity is formed between the boosting piston and the blocking ring. The wet type vehicle brake braking force increasing mechanism effectively achieves increasing of spring pushing force, has the advantages of being small in size, low in weight, stable in brake force, high in reliability and the like, and can be widely applied to normally-closed wet type vehicle brakes.
Description
Technical field
The present invention relates to field of automobile, specifically the enlarging mechanism of a kind of wet type Brake for vehicle braking force (spring force).
Background technique
At present, the normally closed wet type Brake for vehicle of wheel end generally adopts machinery (spring force) to produce braking force, and owing to being subject to the restriction of wheel hub intracavity space size, very limited for the space of mounting spring in break, cannot the large diameter spring of design and installation, the braking torque of wet type Brake for vehicle under this spatial condition is restricted, causes that to manufacture and design the normally closed wet type Brake for vehicle of high pulling torque very difficult, can not promote the use of heavy goods vehicles or big machinery field.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of wet type Brake for vehicle braking force enlarging mechanism, utilization is under same pressure, and the principle that the thrust that piston produces is directly proportional to its active area, to realize spring thrust effective object increasing in fixed space.
For achieving the above object, one end band of the present invention's annular propelling piston is useful on the hole of mounting spring, and propelling piston and spring pack in cylinder body in the lump, and one end of spring is provided with spring adjusting plug; Large end face area is that propelling piston front-end face area n reinforcement piston is doubly ladder-type structure, the large end face of reinforcement piston is relative with the front end of propelling piston to be installed in cylinder body, on cylinder body, between propelling piston and reinforcement piston, be provided with oil-feed interface, between two-piston, fill with hydraulic oil; Back-up ring is contained between the small end outer edge surface and cylinder body of reinforcement piston, brake strip is pressed on the small end face of reinforcement piston with end cover body, roll-shell is contained on axle by bearing, is provided with oil-feed interface between reinforcement piston and back-up ring, between reinforcement piston and back-up ring, forms oil pocket; Between propelling piston, reinforcement piston respectively and between cylinder body, back-up ring and cylinder body and reinforcement piston, be provided with seal ring.
The present invention compared with prior art, by design Hydraulic Double piston in cylinder body, the principle that the thrust that produces of application piston is directly proportional to its active area, utilize the size variation of two-piston end area, realized the increase of spring thrust, solved space little, the problem of spring thrust deficiency, for manufacturing the normally closed wet type Brake for vehicle of high pulling torque, created condition, and, under the condition of identical braking torque, it is little that break has volume, lightweight, braking force is stable, high reliability.Can be widely used in general-utility car, wheeled engineering truck, farm machinery and vehicle, adapt to especially the normally closed wet type Brake for vehicle that explosion-proof, fire prevention, environmental pollution requirement is high, service condition is harsh heavy goods vehicles such as engineering vehicle or big machinery field are used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, propelling piston 3 of the present invention is annular, evenly on end face thereafter all processes porosely, and for mounting spring 2, propelling piston 3 is installed in indent grooved cylinder body 1 together with spring 2, and one end of spring 2 is provided with spring adjusting plug 9; Reinforcement piston 4 is ladder-type structure, the n of the front-end face area that its large end face area is propelling piston 3 doubly, the diameter of bore of diameter of bore and propelling piston 3 is measure-alike, relative being installed in cylinder body 1 of front end of the large end face of reinforcement piston 4 and propelling piston 3, on cylinder body 1, between propelling piston 3 and reinforcement piston 4, be provided with oil-feed interface, between two-piston, fill with hydraulic oil; Back-up ring 5 is installed on the oral area of cylinder body 1, be contained between the small end outer edge surface and cylinder body 1 of reinforcement piston 4, for sealing the cylinder body being formed by cylinder body 1, propelling piston 3, reinforcement piston 4, brake strip 7 use end cover bodies 6 are pressed on the small end face of reinforcement piston 4, roll-shell 8 is contained on axle by bearing, between reinforcement piston 4 and back-up ring 5, be provided with oil-feed interface, between reinforcement piston 4 and back-up ring 5, form oil pocket; Between propelling piston 3, reinforcement piston 4 respectively and between housing 1, back-up ring 5 and housing 1 and reinforcement piston 4, be provided with seal ring.
The running of this boosting mechanism is: pressing brake strip: the end area of supposing propelling piston 3 is s, first in break manufacture, adjust required spring force f, spring force f promotes propelling piston 3 and is moved to the left, in the left end oil pocket of propelling piston 3, produce f/s pressure, under the effect of this pressure, the large end face ns of reinforcement piston 4 produces the thrust of nf, promotes reinforcement piston 4 and is moved to the left pressing brake strip 7, and the n that has realized spring force doubly increases; Brake off: to oiling in the oil pocket between back-up ring 5 and reinforcement piston 4, promote reinforcement piston 4 and move right, corresponding promotion propelling piston 3 Compress Spring 2 that moves to right, realizes absent-mindedness brake strip 7.
