Problems solved by technology

[0008]The purpose of the present invention is to propose a A new engine balancing method, which can not only solve the unevenness of the engine crankshaft pulley when the force is applied to one side, but also effectively avoid the engine suspension cushion caused by the uneven force of the engine. Deformation, and deformation of the bracket due to uneven force; it can also prevent the cooling system and intake and exhaust system failures caused by engine displacement to a certain extent

Embodiment 1

[0033] by attaching figure 2 It can be seen that the present invention relates to a method for balancing uneven force on one side of the crankshaft pulley of the engine. A support mechanism is added between the engine and the air conditioner compressor, and the support mechanism is used as a balancing device to use the support force of the support mechanism to balance the air conditioner. The pulley pull on the crankshaft pulley.

[0034] Specifically, adding a supporting mechanism between the engine and the air-conditioning compressor is to connect an engine connecting bracket 1 through bolts 9 on the engine body 8, the structure of the engine connecting bracket 1, the engine connecting bracket 1 and the engine body 8 It belongs to rigid connection; the engine connecting bracket 8 is connected with the right-hand threaded connecting fork 2 through the hinge bolt 10, and the engine connecting bracket 8 can rotate around the hinge bolt 10 here during the movement, so as to eff...

Embodiment 2

[0036] Embodiment 2 has basically the same structure as Embodiment 1. It is a method for balancing the uneven force on one side of the crankshaft pulley of the engine. A support mechanism is added between the engine and the air-conditioning compressor, and the support mechanism is used as a balancing device. The support balances the pull of the A / C pulley on the crankshaft pulley. Only the installation position of the support mechanism is different. The support mechanism is set on the line connecting the two axes of the engine crankshaft pulley and the air conditioner compressor pulley, so that it can play a supporting role more effectively, and the support structure adopted The shortest distance.

[0037] Specifically, the support mechanism added between the engine and the air-conditioning compressor is on the engine body, and a platform is arranged on the line connecting the two axes of the engine crankshaft pulley and the air-conditioning compressor pulley, and a bolt is in...

Embodiment 3

[0039] Embodiment 3 has basically the same structure as Embodiment 1 or 2. It is a method for balancing the uneven force on one side of the crankshaft pulley of the engine. A support mechanism is added between the engine and the air-conditioning compressor, and the support mechanism is used as a balancing device. The supporting force of the mechanism balances the pulling force of the air conditioner pulley on the crankshaft pulley.

[0040] Said adding a supporting mechanism between the engine and the air-conditioning compressor is to set a supporting mechanism next to the connection belt between the engine body crankshaft pulley and the air-conditioning pulley installed on the air-conditioning compressor bearing, so that the engine body crankshaft pulley and the air-conditioning compressor are installed The air-conditioning pulley of the support is in a tensioned state, reducing the deformation of the engine suspension cushion caused by the uneven force on one side of the engi...

Abstract

The invention discloses a method of balancing uneven stress on the single side of a crankshaft pulley of an engine and a device. A supporting mechanism is added between the engine and an air conditioning compressor; and the supporting force of the supporting mechanism is utilized to balance the tension of an air conditioning belt pulley to the crankshaft pulley with the supporting mechanism as a balancing device. According to the method and the device, addition of the supporting mechanism between the engine and the air conditioning compressor is to arrange the supporting mechanism beside a connecting belt between the crankshaft pulley of an engine body and the air conditioning belt pulley installed on a supporting seat of the air conditioning compressor, so that the crankshaft pulley of the engine body and the air conditioning belt pulley installed on the supporting seat of the air conditioning compressor are in a tightening state, and deformation of a suspension cushion of the engine caused by the condition of uneven stress on the single side of the crankshaft pulley of the engine and deformation of a bracket caused by uneven stress are lowered; and through respective connection of the rotatable balancing device formed by a supporting rod with the engine body and a bracket of the air conditioning compressor, the influence of up and down vibration of the engine on the air conditioning compressor can be effectively prevented.

Description

technical field [0001] The invention relates to a method for balancing parts of a passenger car, in particular to a method for balancing an engine. This engine balancing method is used to balance the unevenness of the engine crankshaft pulley when the force is applied on one side, so as to effectively avoid the deformation of the engine mount cushion and the deformation of the bracket (the bracket's Caused by uneven force), and to a certain extent, it can prevent the occurrence of cooling system, intake and exhaust system failures caused by engine displacement, and belongs to the technical field of passenger car manufacturing. [0002] Background technique: [0003] Usually, the power of a traditional air conditioner requires engine input, and the input form is that the engine 101 drives the pulley 103 of the air conditioner compressor through the crankshaft pulley 102 installed on it (such as figure 1 As shown), the crankshaft pulley 103 will be pulled by the right side u...
