Abstract
The utility model discloses a brake bottom plate which comprises a bottom plate body, wherein one end of the bottom plate body is provided with a camshaft mounting hole, two sides inside the camshaft mounting hole are respectively provided with an oil seal, and the oil seals are embedded into the camshaft mounting hole in an interference fit manner; reinforcing ribs are connected to two sides of the outer wall of the camshaft mounting hole. According to the utility model, the oil seal is added on the mounting hole of the camshaft, so that the oil in the mounting hole can not flow out from the inside, the lubricating effect is better and more durable, the problems of jamming, abrasion, abnormal sound and the like caused by the rotation of the camshaft can be effectively prevented, and the problem that the braking effect is influenced by accelerated abrasion of the camshaft is avoided.
Description
Technical Field
The utility model relates to the technical field of brake accessories, in particular to a brake bottom plate.
Background
A brake backing plate (braking plate) is a key part in a brake backing plate assembly, is a supporting part for fixing a brake shoe assembly and assembling a brake drum in an automobile brake, and is the core of the whole automobile brake. The existing bottom plate structure is only provided with an oil seal on the outer side of the bottom plate, and the part inside the brake is still exposed. When the camshaft passes through a road section with a lot of sand and dust, a small amount of impurities such as sand and dust enter the camshaft mounting hole, lubricating oil in the hole is polluted, the lubrication is failed, and the camshaft rotates and is blocked. And oil in the mounting hole can be followed inside and not have the oily seal survey and flow, causes to rotate abnormal sound and the card and dun scheduling problem accelerate wearing and tearing, influences braking effect.
SUMMERY OF THE UTILITY MODEL
The object of the present invention is to provide a brake spider which solves the above mentioned problems.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
a brake spider comprising: the cam shaft mounting hole is formed in one end of the bottom plate body, oil seals are arranged on two sides of the inner portion of the cam shaft mounting hole, and the oil seals are embedded into the cam shaft mounting hole in an interference fit manner; reinforcing ribs are connected to two sides of the outer wall of the camshaft mounting hole.
Further, the oil seal adopts a framework oil seal.
Further, the two ends of the camshaft mounting hole are provided with L-shaped grooves, an oil seal mounting table is embedded into each L-shaped groove, and the oil seal mounting table is abutted to the outer side of the oil seal.
Furthermore, a central mounting hole is formed in the central position of the bottom plate body.
Furthermore, a plurality of connecting through holes are formed in the bottom plate body, and the connecting through holes are arranged around the central mounting hole.
Furthermore, one end of the bottom plate body, which is far away from the camshaft mounting hole, is connected with a flange, and a supporting pin hole is formed in the flange.
Has the advantages that:
according to the utility model, the oil seal is added on the mounting hole of the camshaft, so that the oil in the mounting hole can not flow out from the inside, the lubricating effect is better and more durable, the problems of jamming, abrasion, abnormal sound and the like caused by the rotation of the camshaft can be effectively prevented, and the problem that the braking effect is influenced by accelerated abrasion of the camshaft is avoided.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention discloses a brake spider comprising: the cam shaft mounting structure comprises a bottom plate body 1, wherein one end of the bottom plate body 1 is provided with a cam shaft mounting hole 2, oil seals 3 are arranged on two sides of the inner part of the cam shaft mounting hole 2, and the oil seals 3 are embedded into the cam shaft mounting hole 2 in an interference fit manner; reinforcing ribs 9 are connected to two sides of the outer wall of the camshaft mounting hole 2.
In this embodiment, the oil seal 3 is a skeleton oil seal, and is press-fitted into the camshaft mounting hole 2 of the base plate in an interference fit manner. Like this camshaft mounting hole 2's both sides all have the skeleton oil blanket to seal, prevent that camshaft mounting hole 2 from getting into the dust, and the lubricated time of injection can be maintained for a longer time, the card when more being difficult to take place to rotate pause the phenomenon.
In this embodiment, the both ends of camshaft mounting hole 2 all set up the L shape groove, and the L shape inslot embedding has oil blanket mount table 4, and oil blanket mount table 4 supports and leans on in the outside of oil blanket 3 to the firmness and the stability of oil blanket 3 installations have been improved.
In this embodiment, a central mounting hole 5 is formed in the central position of the bottom plate body 1.
In this embodiment, a plurality of connecting through holes 6 are provided on the bottom plate body 1, and the plurality of connecting through holes 6 are arranged around the central mounting hole 5.
In this embodiment, one end of the bottom plate body 1, which is far away from the camshaft mounting hole 2, is connected with a flange 7, and a support pin hole 8 is formed in the flange 7.
According to the utility model, the oil seal is added on the mounting hole of the camshaft, so that the oil in the mounting hole can not flow out from the inside, the lubricating effect is better and more durable, the problems of jamming, abrasion, abnormal sound and the like caused by the rotation of the camshaft can be effectively prevented, and the problem that the braking effect is influenced by accelerated abrasion of the camshaft is avoided. An oil seal mounting table is milled away from the brake bottom plate, so that the weight is reduced; and can change spare part fast convenient.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
