Abstract
The utility model discloses a novel servant brake eccentric shaft structure, including eccentric shaft body (1), rivet (2) and gyro wheel (3), set up on one side of eccentric shaft body (1) base with the open slot of stepping down (4) of gyro wheel (2) looks adaptation, install gyro wheel (3) in open slot of stepping down (4) through rivet (2), and this gyro wheel (3) diameter is greater than the groove depth of open slot of stepping down (4). The utility model discloses a novel servant brake eccentric shaft structure, simple structure changes the sliding friction between eccentric shaft and the shoe block subassembly into rolling friction, and the eccentric shaft rotational resistance is little, and difficult wearing and tearing can add lubricating grease to the recess of stepping down in, avoid friction material to contact lubricating grease, and the eccentric shaft is lubricated effectual, and the braking effect is better.
Description
Technical Field
The utility model relates to a brake ware accessory technical field, concretely relates to novel servant brake eccentric shaft structure.
Background
When the conventional servo brake brakes, the eccentric shaft rotates and forms sliding friction with the shoe block assembly, the eccentric shaft has large rotation resistance, so that the eccentric shaft is easy to wear, and dust generated by grinding between the eccentric shaft and the shoe block assembly is stained on a friction material to cause abnormal braking sound; in addition, the lubricating grease can only be added on the outer surface of the eccentric shaft, and when the brake is braked, the friction material is easy to contact with the lubricating grease, so that the braking effect is influenced. Therefore, it is necessary for those skilled in the art to develop a new eccentric shaft structure of the servant brake.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the deficiencies existing in the prior art, providing a novel servant brake eccentric shaft structure.
In order to achieve the purpose of the utility model, the utility model provides a technical scheme as follows: the utility model provides a novel servant brake eccentric shaft structure, includes eccentric shaft body, rivet and gyro wheel, eccentric shaft body base one side set up with the open slot of stepping down of gyro wheel looks adaptation, install the gyro wheel in the open slot of stepping down through the rivet, and this gyro wheel diameter is greater than the groove depth of the open slot of stepping down.
Based on the technical scheme, compared with the prior art, the utility model have following technical advantage:
the utility model discloses a novel servant brake eccentric shaft structure, simple structure changes the sliding friction between eccentric shaft and the shoe block subassembly into rolling friction, and the eccentric shaft rotational resistance is little, and difficult wearing and tearing can add lubricating grease to the recess of stepping down in, avoid friction material to contact lubricating grease, and the eccentric shaft is lubricated effectual, and the braking effect is better.
Drawings
Fig. 1 is the structure schematic diagram of the novel servant brake eccentric shaft of the present invention.
In the figure: 1. the eccentric shaft body, 2, rivets, 3, rollers and 4 abdicating open slots.
Detailed Description
The invention is further explained below with reference to the drawings and examples.
As shown in fig. 1, a novel servant brake eccentric shaft structure, including eccentric shaft body 1, rivet 2 and gyro wheel 3, set up the open slot of stepping down 4 with 3 looks adaptations of gyro wheel on one side of the base of eccentric shaft body 1, install gyro wheel 3 in the open slot of stepping down 4 through rivet 2, and the 3 diameters of this gyro wheel are greater than the depth of the open slot of stepping down 4 for 3 outer circumferences of gyro wheel always have one section arc to expose the open slot of stepping down 4 outsides, so that when eccentric shaft body 1 rotates, utilize to form rolling friction between gyro wheel 2 and the shoe block subassembly, thereby prop open the shoe block subassembly.
The foregoing is illustrative and explanatory of the invention and is not intended to limit the advantages attainable thereby, and it is within the scope of the present application to practice the invention with simple modifications to the structure and/or one or more of the advantages achieved in some embodiments.
Claims (1)
1.
