Description
Technical field
The utility model relates to automobile technical fields, and in particular to a kind of passenger car ventilating retarding disk.
Background technique
The thermal stability of braking system plays a decisive role to the constancy of brake efficiency, and the braking system of overheat will lead to bright
Aobvious heat fading, frictional decrease, braking distance lengthening, generation vapour lock etc..Due to the raising of vehicle weight and maximum speed,
To the thermal stability of braking system, more stringent requirements are proposed.
Vehicle energy is converted to thermal energy when braking, is passed to brake disc, brake or is diffused in air by convection current, whole
The heat of a system is adjusted by brake disc.Massive brake disc has very big thermal capacity, when can receive braking well
The frictional heat of generation avoids making friction block heat fade effect occur due to system overheat, and the material and structure of brake disc are to whole
The temperature of a braking system has a significant impact.In braking process, on the one hand frictional heat energy is braked disk and absorbs storage, another party
Face as the temperature rises, is given out heat by the convection current and surface emissivity of brake disc adjacent components, surface and ventilating duct
It goes.Thermal energy flow into outflow balance the result is that brake disc brake when temperature raising and subsequent cooling.Currently mainly with
Based on the application of straight line ventilating duct brake disc, although which may be implemented the left-right universal of brake disc, but its heat dissipation is cold
But performance and cooling are weaker than curve vent air pipe brake disc.
Chinese patent CN201944154U discloses a kind of improved forced ventilation formula brake disc, the diameter of brake disc inner face
To being equipped with several evenly spaced radial flow deflectors, flow deflector be arranged to be in outward by the center of brake disc divergent shape gradually open form
Flight, brake disc synchronous high-speed rotates when the vehicle is running, and the vortex type vented cavity constituted between flow deflector is by brake disc
The heart forces air draft to circumferencial direction, effectively increases the air mass flow of brake disc inner surface, improves brake disc ventilation and heat shape
Condition, the patent constitute vortex type vented cavity between flow deflector, are forced by the way that radial flow deflector is arranged in brake disc inner face
Air draft improves brake disc ventilation and heat situation, but patent increase flow deflector can bring difficulty, flow deflector to the manufacture of brake disc
It is easy to loosen, and does not disclose the ventilation cavity configuration between flow deflector further.
Utility model content
The purpose of this utility model is exactly to provide a kind of passenger car ventilating retarding disk to solve the above-mentioned problems.
The purpose of this utility model is achieved through the following technical solutions:
A kind of passenger car ventilating retarding disk, including brake disc ontology, the brake disc ontology include disk cap, the first disk
With the second disk, the annular solid between first disk and the second disk is radially provided with several evenly spaced curve ventilations
Road, the curve vent air pipe are gradually opened in the shape of a spiral outward by the center of brake disc ontology, the opening section of the curve vent air pipe
