Abstract
The invention discloses an oil inlet pipe assembly of an engine in-cylinder brake. The oil inlet pipe assembly is used for being installed on the top of an air cylinder cover. The engine in-cylinder brake comprises an electromagnetic valve. The oil inlet pipe assembly comprises an oil inlet pipe and two pipe support assemblies. The oil inlet pipe is provided with a plurality of connectors. The first connector of the oil inlet pipe is inserted into an oil outlet hole of the air cylinder cover, and the second connector and the third connector of the oil inlet pipe are connected to an oil inlet hole of the electromagnetic valve through oil bolts. The two pipe support assemblies are arranged on the oil inlet pipe. The two pipe support assemblies are installed on a brake shell and a rocking arm shaft through bolts respectively. The portion, between the two pipe support assemblies, of the oil inlet pipe is formed by a hose, and the other portions of the oil inlet pipe are formed by hard pipes. According to the oil inlet pipe assembly of the brake, due to the fact that the soft and hard structure is adopted for the oil inlet pipe of the brake and the two pipe clamp support assemblies are assembled for fixing, vibration of the oil inlet pipe of the brake in the using process is lowered.

Summary of the invention
The object of the present invention is to provide a kind of oil inlet pipe assembly of engine cylinder inner brake, thus overcome the defect that in prior art, easily rupture in oil connection place.
For achieving the above object, the invention provides a kind of oil inlet pipe assembly of engine cylinder inner brake, this oil inlet pipe assembly is for being arranged on the top of cylinder head, described engine cylinder inner brake comprises solenoid valve, wherein this oil inlet pipe assembly comprises: oil inlet pipe, it has multiple joint, first joint of this oil inlet pipe is inserted into the oil outlet of described cylinder head, second joint and the 3rd joint of described oil inlet pipe all passed through the oil inlet hole that oil draining bolt is connected to described solenoid valve, and two pipe holder assemblies, it is arranged on described oil inlet pipe, these two pipe holder assemblies are arranged on brake casing and pitman arm shaft by bolt respectively, oil inlet pipe between wherein said two pipe holder assemblies is made up of flexible pipe, and the oil inlet pipe of remaining part is made up of hard tube.
Preferably, in technique scheme, described first joint straight cutting is entered the oil outlet of described cylinder head and is fixed by oil pipe pressing plate, and utilizes O type circle to seal.
Preferably, in technique scheme, each pipe clamp bracket component comprises gum cover and two pipe clamp supports, and described gum cover is for being inserted in the cylindrical of described oil inlet pipe, described two pipe clamp supports clamp this gum cover up and down, and are stacked on described brake casing by described pipe clamp bracket component by bolt.
Compared with prior art, the present invention has following beneficial effect: according to break oil inlet pipe modular construction advantages of simple of the present invention, adopted by break oil inlet pipe and softly add rigid structure and equipped two pipe clamp bracket components are fixed, reduce the vibration in use of break oil inlet pipe, break oil inlet pipe is avoided to rupture, break oil inlet pipe engine oil pressure is kept within the acceptable range, thus prevents break driven plunger to lose efficacy, ensure the normal use of engine cylinder inside brake function.
