Abstract
An automobile brake regulating arm comprises a shell, wherein a worm wheel and a worm meshed with the worm wheel are arranged inside the shell, a spline hole formed inside one end of the shell is matched with an outer spline of an automobile cam shaft, and the other end of the shell is provided with a sleeve hole. The automobile brake regulating arm is practical in structure, convenient to operate, high in reliability, and reasonable in manufacturing process.
Description
Technical field
The utility model belongs to the auto parts machinery field, relates to a kind of automobile braking adjusting arm.
Background technique
Along with the continuous growth of automobile amount, also increase substantially as the demand of the braking adjusting arm of auto parts and components, at this moment, braking adjusting arm improved becomes a kind of trend.
At present, the structure of automobile braking adjusting arm commonly used comprises a housing, is provided with intermeshing worm gear and worm screw together in housing, and worm gear set is contained on the brake rod set on the automobile, and circumferentially fixing between the two, and brake rod passes the both end sides of housing.The distolateral cover plate that is provided with of housing, cover plate is so that form to be used for holding the enclosed cavity of worm gear and worm screw between housing and the cover plate.
In the vehicle using process, owing to the wearing and tearing of Brake shoe lining or brake drum lose the reasons such as circle, cause brake clearance to increase, cause the time lengthening of braking, on the other hand, because the brake drum of each wheel of vehicle is different from the degree of wear of Brake shoe lining, the brake clearance between each wheel does not wait, cause vehicle when braking, sideslip to occur, bring potential safety hazard to Vehicle Driving Cycle.In order to guarantee that vehicle has best braking effect, require break must keep having between brake shoe and the brake drum normal, a rational minimum clearance.At present, the structural type of braking adjusting arm is a lot, except several structures of comparative maturity, has some to have some problems the manufacturing of structure and technique, for the conversion of new technology has increased difficulty.
Summary of the invention
The utility model provides a kind of automobile braking adjusting arm, and its purpose mainly is to make the structure of automobile brake arm more practical, more convenient to operate, and unfailing performance is higher, and manufacturing process is more reasonable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automobile braking adjusting arm, comprise be equipped with in housing, the housing worm gear and with the worm screw of its engagement, an end of described housing is provided with inner splined hole, this inner splined hole cooperates with external splines on the automobile brake camshaft; The other end of described housing is provided with trepanning.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the profile of tooth height of the spline tooth of described inner splined hole is 0.7mm.
2, in the such scheme, the internal diameter size of described inner splined hole is 77 ± 0.4 mm.
3, in the such scheme, the outside of inner splined hole is provided with lubricated oil hole on the described housing.
4, in the such scheme, the internal diameter size of described trepanning is 30 ± 0.2 mm.
5, in the such scheme, the overall length of described housing is of a size of 187.6 mm.
6, in the such scheme, described inner splined hole and trepanning distance of center circle between the two is 120 ± 0.8 mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is simple in structure, the braking reliability is high, and is easy to operate and cost of production is low, has larger promotional value.
