Abstract
The utility model discloses a pawl pressure adjusting device of a rear brake cylinder. The pawl pressure adjusting device comprises a gap adjusting pawl hinged on the outer wall of a cylinder body, wherein the gap adjusting pawl is matched with an adjusting ratchet wheel; a pressure spring is pressed outside the gap adjusting pawl; the end part of the pressure spring is fixed on the outer wall of the cylinder body by a screw; a locking sheet is arranged between the pressure spring and a screw cap of the screw in a cushioning way; an adjusting sliding groove is arranged on the locking sheet; and the screw can slide along the adjusting sliding groove. The pawl pressure adjusting device can realize the adjustment on the pre-pressure of the gap adjusting pawl, has simple structure and small size, and the car hydraulic brake cylinder adopting the pawl pressure adjusting device is convenient to operate, and easy to mount and use.
Description
Technical field
The utility model relates to brake pump field behind the automobile, relates in particular to a kind of ratchet regulator of rear braking subpump.
Background technique
Brake cylinder is the indispensable part of braking system, and its significant feature is to push brake block, and brake block friction brake drum makes speed of a motor vehicle reduction and static.Step on brake back master cylinder generation thrust hydraulic oil is overwhelmed brake cylinder, under the pressure of pump housing piston, brake oil pipe is extruded oil pipe and makes braking function to each wheel cylinder diffluence.When the releasing of brake plate.Oil outlet in the general braking pump can be closed, and filler opening is opened, and brake oil is back in the general braking pump from each wheel cylinder, gets back to reset condition.Brake cylinder structure in the past, its cylinder body are the structural design that the top directly has filler opening mostly, and this kind structure does not have dust guard, and long-term use lets dust and moisture get into cylinder body easily, causes faults such as seizure of piston and leakage of oil.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content
The purpose of the utility model is to provide a kind of ratchet regulator of rear braking subpump, the adjustment that can realize exchanging crack pawl precompression, the hydraulic vehicle braking wheel cylinder easy to operate, simple in structure, that volume is little, easy mounting is used.
For solving the problems of the technologies described above, the technological scheme of the utility model is following:
The ratchet regulator of rear braking subpump; Include the accent crack pawl that is articulated in outer wall of cylinder block, transfer crack pawl and adjustment ratchet to be complementary, transfer crack pawl external pressure to be equipped with making leaf spring; Screw is passed through on outer wall of cylinder block in the end of making leaf spring; Pad is provided with lock sheet between the nut of said making leaf spring and described screw, has and adjust chute on the lock sheet, and screw can slide along the adjustment chute.
Be provided with pad between described lock sheet and the making leaf spring.
Compared with present technology, the beneficial effect of the utility model is:
The utility model can realize exchanging the adjustment of crack pawl precompression, and is easy to operate, hydraulic vehicle braking wheel cylinder simple in structure, that volume is little, easy mounting is used.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model.
Fig. 2 is the plan view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation:
Referring to accompanying drawing, the ratchet regulator of rear braking subpump includes the accent crack pawl 2 that is articulated in cylinder body 1 outer wall; Transfer crack pawl 2 and adjustment ratchet to be complementary, transfer crack pawl external pressure to be equipped with making leaf spring 3, the end of making leaf spring 3 is fixed on cylinder body 1 outer wall through screw 4; Pad is provided with lock sheet 5 between the nut of making leaf spring 3 and described screw; Have and adjust chute 7 on the lock sheet 5, screw can slide along the adjustment chute, is provided with pad 6 between lock sheet and the making leaf spring.
Claims (2)
1. the ratchet regulator of rear braking subpump; Include the accent crack pawl that is articulated in outer wall of cylinder block, transfer crack pawl and adjustment ratchet to be complementary, transfer crack pawl external pressure to be equipped with making leaf spring; Screw is passed through on outer wall of cylinder block in the end of making leaf spring; It is characterized in that: pad is provided with lock sheet between the nut of said making leaf spring and described screw, has and adjust chute on the lock sheet, and screw can slide along the adjustment chute.
