Description
Technical field
The utility model belongs to aluminium-alloy piston technical field, is specifically related to a kind of lightweight aluminium-alloy piston.
Background technology
Along with us country's level of the productive forces and the raising of economic and technique level, the standard of living of people have also been obtained raising, and automobile energy consumption is required more and more stricter by country, and the comfortable property of automobile, low oil consumption are more and more subject to people's attention. Car engine machine vibration and the noise brought by vibration have become the problem that in Automobile Motor Design, attention rate improves day by day. In the working cycle of engine, quickly, and speed is very uneven for the movement velocity of piston. At upper bottom dead center position, the speed of piston is zero, and the position and speed in the middle of upper lower dead center reaches the highest. Owing to piston does the motion of high-speed straight-line repeatedly in cylinder, very big mass force must be produced on piston, wrist pin and connecting rod, thus bring periodic vibration, produce noise, affect the ride comfort of people, too increase oil consumption, inadequate energy-conserving and environment-protective.
Practical novel content
The purpose of this utility model is to provide a kind of lightweight aluminium-alloy piston, to solve in above-mentioned background technology the problem proposed.
For achieving the above object, the utility model provides following technical scheme: a kind of lightweight aluminium-alloy piston, comprise piston skirt, piston, coupling shaft and union lever, described internal piston is provided with pistion recess, described pistion recess is provided with titanium alloy stiffening web, described piston skirt is provided with and connects hole, described titanium alloy stiffening web is fixedly connected with pistion recess and piston skirt, described union lever end is provided with union lever termination, described union lever termination and union lever are structure as a whole, it is provided with connecting rod bores in the middle part of described union lever termination, described connecting rod bores is rotationally connected by coupling shaft and connection hole, described union lever is hollow structure, described union lever inside is provided with titanium alloy bar core, described titanium alloy bar core is fixedly connected with union lever.
Preferably, described titanium alloy stiffening web is vertically arranged each other.
Preferably, the internal diameter of described connection hole, connecting rod bores is identical with coupling shaft external diameter.
Preferably, the height of described titanium alloy stiffening web is identical with the height of pistion recess.
Preferably, described union lever termination is circular setting.
Technique effect of the present utility model and advantage: this lightweight aluminium-alloy piston is owing to being provided with pistion recess, it is possible to make the weight saving of piston a lot; Owing to being provided with titanium alloy stiffening web, it is ensured that the intensity of piston reaches requirement; Owing to being provided with titanium alloy bar core, it is possible to accomplish that the diameter of union lever is smaller, reduce the weight of union lever, the intensity that union lever reaches very high can also be ensured simultaneously; The utility model, under ensureing that structural strength meets the requirements of situation, alleviates the weight of structure, it is achieved that lightweight, decreases vibration, it is to increase the comfortable property that people ride, and also reduces oil consumption simultaneously, economizes on resources, economic environmental protection.
