Abstract
The utility model discloses a kind of compact type that is applied to disk type braker and divide pump assembly, comprise a minute pump case (1), wheelcylinder piston (2), wheel cylinder shoe plate (3), main sliding axle (4), the inwall (8) of minute pump case between described main sliding axle (4) and minute pump case (1) is step-like structure, and the wheel cylinder housing parts (6) of the main sliding axle of described installation maintains an equal level on the same line with the main body (7) of minute pump case.The utility model is conducive to the convenient for assembly of main sliding axle, and it is simple in structure, it is easy to process, and has also reduced cost of production, has also improved break whole work efficiency.
Description
Technical field
The present invention relates to a kind of Brake for vehicle, belong to electric motor car and manufacture field, specifically relate to minute pump assembly (being brake calipers) that a kind of electric motor car break is used.
Background technique
Electric motor car is an emerging vehicle, and its load-carrying and F-Zero are between bicycle and motorcycle, and the main flow of its break is that front and back wheels all adopts drum brake substantially at present, and its braking effect is unsatisfactory.Because drum brake heat dispersion is poor, in braking process, produce amount of heat, very easily cause that brake block temperature raises, friction factor declines, cause heat fade, retardation efficiency declines, insensitivity variation and in braking because excess Temperature produces noise; Once rainwater enters drum brake, can make friction factor decline, cause water fade, and water is difficult, and out water is restorative poor, retardation efficiency declines, and the Security of driving reduces.
This electric motor car break is disk type braker, main pump assembly, minute pump assembly (being brake calipers), brake disc etc., consists of, and its brake disc is exposed in air and high speed rotating, and radiating effect is good, and braking ability is stable; Brake disc is followed wheel and is rotated together, water or mud can be thrown away, so water is restorative better; Greatly improved the Security of driving; Long service life and at when braking noise free, it is convenient to change.The trend of industry development is to substitute drum brake with disc type brake.But the inwall of minute pump case between the main sliding axle of its minute pump assembly and minute pump case assembling has ring shaped slot, and it needs special T-shape milling cutter processing, and milling process is loaded down with trivial details; Its wheel cylinder housing parts (i.e. main slip axis hole) that main sliding axle is installed is compared with the main body of minute pump case, in raised position, has affected the integral installation of break.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of main sliding axle processing compact type simple, convenient for assembly that is conducive to divide pump assembly.
Object of the present invention realizes by following technical solution: compact type divides pump assembly, comprise a minute pump case, wheelcylinder piston, wheel cylinder shoe plate, main sliding axle, the inwall of minute pump case between described main sliding axle and minute pump case is step-like structure, and the wheel cylinder housing parts of the main sliding axle of described installation maintains an equal level on the same line with the main body of minute pump case.
Adopt after the present invention, main sliding axle and the inner wall section between minute pump case of minute pump case are improved to " step-like structure " by former " ring shaped slot ", and its processing mode only need be used a common milling cutter for this reason; The wheel cylinder housing parts of main sliding axle is installed and is compared by former " outwardly convex " and be improved to " maintaining an equal level on the same line " with the main body of minute pump case, so that the design of product and assembling.Therefore, the present invention is conducive to the convenient for assembly of main sliding axle, and it is simple in structure, it is easy to process, and has also reduced cost of production, has also improved the whole work efficiency of break.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and mode of execution, the present invention is described in further detail.
Fig. 1 is the structural representation that compact type of the present invention divides pump assembly.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Fig. 4 is that the C of Fig. 1 is to view.
Embodiment
Known referring to figs. 1 through Fig. 4, the compact type that the present invention is applied in electric motor car divides pump assembly, comprise minute pump case 1, wheelcylinder piston 2, wheel cylinder shoe plate 3, main sliding axle 4, the inwall 8 of minute pump case between described main sliding axle 4 and minute pump case 1 is step-like structure, the main body 7 of the wheel cylinder housing parts 6 of the main sliding axle of described installation (i.e. main slip axis hole) and minute pump case maintains an equal level on the same line D (as shown in Figure 4, remain on same level line, do not have projection not cave in yet, be convenient to product specification and assembling, not acceptor's impact of axis hole of sliding.Under original product state, main slip axis hole outwardly convex is higher, affects product specification and installation).
