Abstract
The utility model provides a structure-improved brake pump casing of a motorcycle, which belongs to the technical field of the motorcycle and solves the problems that the brake pump casing in the existing hydromechanical brake has complicated processing technique, unstable product quality, etc. The structure-improved brake pump casing of a motorcycle comprises a body made of plastic, wherein metal inserts are arranged at screw holes in the body; the metal inserts are fixedly connected together with the body; inner holes of the metal inserts are provided with screw threads. Usually, the metal inserts fixedly connected together with the body are arranged at an oil outlet pipe screw hole, a backing mirror screw hole, a fixing seat screw hole and an oil cup cover screw hole on the body. The utility model adopts plastic to make the body of the casing, so the cost of the products is relatively low. At the same time, the plastic casing is formed one step through a mould, so the qualified rate of the products is high, the quality of the products is stable, and the producing process is greatly simplified.
Description
Technical field
The utility model belongs to technical field of motorcycles, particularly a kind of structure-improved to being done on the brake for motorcycle master cylinder.
Background technology
On existing motor bike, hydraulic brake is a kind of widely used drg.Hydraulic brake adopts the structure of brake pump and brake clamp split, and the pressure that utilizes brake pipe transmission brake pump to produce promotes the caliper piston with pressing friction sheet and brake disc, reaches and brakes effect fast and effectively.
In hydraulic brake, the housing of brake pump normally adopts metallic material to make.The advantage of metal shell is the mechanical strength height, but weak point is its processing technology complexity, the quality instability of product, occurs inferior-quality product easily, directly has influence on the safe handling of motor bike; Simultaneously, the cost of product is also higher.
Summary of the invention
The purpose of this utility model is in order to solve the existing above-mentioned weak point of existing motorcycle brake pump case, a kind of structure improved motorcycle brake pump case to be provided, and makes it have that processing technology is simple, cost of product is low, the characteristics of constant product quality.
For achieving the above object, the utility model has adopted following technical proposal: this structure improved motorcycle brake pump case comprises a body that adopts plastics to make, screw place in the body is provided with metal insert, and metal insert and body are fixed together, and has screw thread in the endoporus of metal insert.
Particularly, oil outlet pipe screw place, side mirror screw place, permanent seat screw place, the oil cup cap screw place on body is provided with the metal insert that is fixed together with body usually.
The body that the body that the utility model has adopted plastics to make comes the alternative metals material to make can reduce the cost of product; Simultaneously, the screw place that connects with other part at body is provided with metal insert, connects firmly guaranteeing, makes the technical indexs such as mechanical strength of housing meet the standard-required of brake pump.
Compare with existing metal braking pump case, the utility model is owing to adopted plastics to make enclosure body, and the cost of its product is lower; Simultaneously, plastic casing is by the disposable shaping of mould, so qualification rate height, the steady quality of product.In addition, the technology of producing this product has also been simplified greatly.
Description of drawings
Fig. 1 is the structural representation of the structure improved motorcycle brake pump case that provides of the utility model.
Fig. 2 is to use the generalized section of the motorcycle brake pump of the utility model structure.
Among the figure, 1, body; 2, metal insert; 3, cylinder body; 4, side mirror screw; 5, oil cup cap screw; 6, oil outlet pipe screw; 7, piston; 8, oil cup cap; 9, screw.
The specific embodiment
As depicted in figs. 1 and 2, the body 1 of this structure improved motorcycle brake pump case adopts plastics to make.Screw place in body 1 is provided with metal insert 2.Screw shown in Figure 1 has oil cup cap screw 5, side mirror screw 4 and oil outlet pipe screw 6.When producing, need only these screw place injection moldeds that metal insert 2 directly are positioned over body 1 mould, metal insert 2 and plastic body 1 are fixed together.Have screw thread in the endoporus of metal insert 2.Because body 1 connects with other part by metal insert 2,, has identical mechanical strength with metal body so the intensity of its connection is not subjected to body 1 to adopt the influence of plastics.
As shown in Figure 2, oil cup cap 8 is placed on the body 1, is screwed in the oil cup cap screw 5 by screw 9, and oil cup cap 8 is fixed on the body 1.
As depicted in figs. 1 and 2, in the present embodiment, 1 inner cylinder place also is provided with columnar metal cylinder body 3 at body, and metal cylinder body 3 is connected in the body 1.Because plastics might produce distortion in process of production, cause the variation of size, therefore, can guarantee that its size can not change, and makes the steady quality of product by embed the mode of metal cylinder body 3 at the oil cylinder place.Identical with common brake pump, be provided with piston 7 in the cylinder body 3.
The utility model can be widely used on the various dissimilar motorcycle brake pumps.
