Abstract

An engine linking bracket for vehicle comprises a bracket body (1) connected with a speed change box and provided with a connection first hole (4) for adapting the speed change box; a second connecting arm (3) which is orthogonal with different face and mounted on the one end of the body (1), with a connection second hole (5) for adapting the cylinder body of the engine; a first connecting arm (2) which is orthogonal with different face and mounted on the other end of the body (1), with a connection third hole (6) for adapting the other surface of the cylinder body of the engine. The body (1) and the first connecting arm (2) and the second connecting arm (3) form holding shape. The linking bracket of holding shape is used to connect the engine and the bottom of the speed change box to make the engine and the speed change box form an entirety, therefore the engine assembly vibration frequency is increased and the resonance point of engine power assembly and entire car is avoided, so that the engine can reduce noise during running up. The invention has features of simple structure and lower cost.

Description

Engine joining-up bracket for automobile
Technical field
The present invention relates to a kind of engine joining-up bracket for automobile, relate in particular to the support that a kind of vehicular engine connects change speed gear box.
Background technology
At present, because vehicular engine in most of the cases uses the punching oil drain pan, in change speed gear box and the driving engine connection procedure, only have change speed gear box top partial sum engine cylinder-body to connect, the change speed gear box bottom is in unsettled.Driving engine and change speed gear box are difficult to become an overall operation.Such fixed form can produce than big bang and noise under vehicular engine high-speed operation state, and has caused car load to produce big noise in the car when running at high speed, and causes the car load noise can't satisfy the traveling comfort requirement.
Summary of the invention
The technical problem to be solved in the present invention is, in order to remedy the weak point that available engine connects support, and provide a kind of simple in structure, connect engine joining-up bracket reliable, good damping result.
The present invention solves the problems of the technologies described above to adopt following technical scheme:
A kind of engine joining-up bracket for automobile comprises the rack body that connects change speed gear box, and the connecting bore of adaptive change speed gear box is arranged on the rack body; Body one end is provided with the connecting arm of antarafacial quadrature, and the connecting bore of adaptive engine cylinder-body is arranged on the arm; It is characterized in that: at the body other end the also connecting arm of antarafacial quadrature is set, the connecting bore of adaptive engine cylinder-body another side is arranged on the connecting arm; Rack body and two connecting arms form embraces the folder shape.
For the ease of adjust error in installation: the hole on the described connecting arm is a waist shaped hole.
Good effect of the present invention is, owing to adopt the connection support of embracing the folder shape, be used to connect vehicular engine body and change speed gear box bottom, make driving engine better be connected as a whole with change speed gear box, improved vehicular engine assembly oscillation frequency, avoid the resonance point of vehicular engine dynamic assembly and car load, make vehicular engine in the high engine speeds operation process, can reach the purpose that reduces noise.The technical scheme of using is simple, and the tapped bore on the existing vehicular engine of utilization is connected with the tapped bore above the change speed gear box, and cost is lower, implements simply, and effect is obvious.
By analyzing and verification experimental verification, before this connection support is not installed, test for the noise that car load is correlated with, raising along with engine speed, noise reaches peak value 94dB in the car load car in the vehicular engine high-speed operation, under the high-speed operation situation, the result of noise can not satisfy the travelling comfort requirement in the car load car.Between vehicular engine and change speed gear box, install and connect support, we are under identical environment and test criteria situation, carried out comparing test for noise in the car load car, the test results that obtains after increasing damping frame has satisfied fully in desired expected value of stage on-test.Under the high engine speeds operating condition, increasing the interior noise of car load car that vibration damping connects support and do not increase damping frame, to have in a big way the pair of falling, noise peak to decrease by 10dB (A) many.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is a D structure scheme drawing of the present invention.
Fig. 2 is a front view of the present invention.
Fig. 3 is a left view of the present invention.
Fig. 4 is a birds-eye view of the present invention.
Among the figure: 1. rack body, 2. first connecting arm, 3. second connecting arm, 4. first hole, 5. second hole, 6. the 3rd hole.
The specific embodiment
Shown in Fig. 1,2,3,4, a kind of engine joining-up bracket for automobile comprises the rack body 1 that connects change speed gear box, and connection first hole 4 of adaptive change speed gear box is arranged on the rack body 1; Body 1 one ends are provided with connection second hole 5 that adaptive engine cylinder-body is arranged on second connecting arm, 3, the second connecting arms 3 of antarafacial quadrature; It is characterized in that: at body 1 other end also first connecting arm 2 of antarafacial quadrature is set, connection the 3rd hole 6 of adaptive engine cylinder-body another side is arranged on the first arm 2; Rack body 1 and first connecting arm 2, second connecting arm 3 form and embrace the folder shape.
For the ease of adjust error in installation: the 3rd hole 6 on described first connecting arm 2 is waist shaped hole.
Installation site and method are as follows:
Two arms that support is stretched are connected with the relevant tapped bore of exhaust side with the air inlet of vehicular engine cylinder body respectively.
