Embodiment Construction

[0040] Such as Figure 1 to Figure 4 , Figure 11 to Figure 14As shown, the automobile steering and braking integrated spherical oil-air pump includes a cylinder head 2, a cylinder body 7, a piston 3, a turntable 5, a center pin 4, a main shaft 6, a main shaft support 10, a cylinder block seat 8, etc., and the cylinder head 2 and the cylinder body 7 has a hemispherical inner cavity, the upper end of the cylinder body 7 and the lower end of the cylinder head 2 are connected by B screws 13 to form a spherical inner cavity, the fractal surface of the cylinder body 2 and the cylinder body 7 passes through the diameter of the spherical inner cavity, and the cylinder body 2 and the cylinder body 7. The connection surface is provided with a connection flange and positioned by pins. According to the installation space requirements on the car, the flange part has been given way without affecting the connection reliability; the piston 3 has a spherical top surface, and the spherical top...

Abstract

The invention discloses a vehicle steering and brake integrated spherical oil-and-air pump. When a piston (3) and a rotary table (5) swing around a center pin (4) relatively, a work chamber V1 (1001) and a work chamber V2 (1002) of which the volumes change alternately and a work chamber V3 (1003) and a work chamber V4 (1004) of which the volumes change alternately are formed in a spherical inner cavity; the work chamber V1 (1001) and the work chamber V2 (1002) are used as air pumps, the work chamber V3 (1003) and the work chamber V4 (1004) are used as oil pumps, and seals are arranged among a hydraulic oil circulation system, a compressed air circulation system and a lubrication oil circulation system, so that steering power-assisting hydraulic oil, compressed air and lubrication oil circulate independently. A steering oil pump and a brake air pump are integrated in one spherical pump, the structure of an existing steering and brake system of a diesel engine vehicle is simplified, the cost is reduced, and working efficiency is improved.

Description

technical field [0001] The patent of the invention relates to a spherical oil-gas pump integrated with steering and brake of an automobile. Background technique [0002] At present, for the steering system and braking system of automobiles, some models use two independent oil pumps to control steering and braking respectively, and some models, especially those using diesel engines, use steering oil pumps and brake air pumps respectively; The oil pump and the brake air pump are two independent components that provide power to the steering oil pump and brake air pump through the engine. However, since the steering oil pump and the brake air pump are two independent parts, the production cost is high, the work efficiency is low, the power of the engine is consumed, and the limited space around the gearbox of the diesel engine car is occupied, and the noise generated by the air compressor is used for the brake air pump. And vibrate a lot. [0003] The spherical compressor is a...
