Description
Technical field
The invention belongs to the motor-tricycle technical field, specifically, the particularly engine mounting system of motor-tricycle.
Background technology
Driving engine is the propulsion source of motor-tricycle, also is the soruce of vibration of an inherence, the change in torque that causes like the shake of torque ripple, idling, car load starting and speed change etc.The driving engine of motor-tricycle is by suspension system supporting location; Suspension system can effectively be controlled engine vibration and transmit to the chassis; Play separating vibration; Cause the transmission of wheel, suspension system vibration to isolate Uneven road, and isolate the noise transfer that produces because of engine vibration etc. to driving engine.At present; The general-duty suspension system of motor tricycle engine adopts simple 4 arrangement forms; Its 4 are all adopted support, compression coil spring and compression rubber mount etc., relatively poor to the isolation and the locating effect of engine vibration, particularly little for the buffer action of driving engine vertical shake and torque vibration; Cause the vibration of motor-tricycle car load bigger easily, thus the traveling comfort that influence is taken.
Summary of the invention
Technical matters to be solved by this invention is the suspension system of motor tricycle engine that provides a kind of vibration isolating effect good.
Technical scheme of the present invention is following: a kind of suspension system of motor tricycle engine; Comprise vehicle frame left side longeron, vehicle frame right vertical beam, the outstanding journal stirrup in a driving engine left side, the outstanding journal stirrup of engine right, tie-beam, preceding suspending cushion, preceding bearing, back suspending cushion and rear support; Wherein vehicle frame left side longeron and vehicle frame right vertical beam laterally arrange; The left and right outstanding journal stirrup of said driving engine is fixed on the middle part of a tie-beam separately, and the left and right longeron of this tie-beam and vehicle frame parallels, and the rear end of tie-beam is fixed on the suspending cushion of back; This back suspending cushion is installed on the cantilever end of rear support, and the root of rear support and cooresponding chassis side rail fix; On the suspending cushion, this preceding suspending cushion was installed on the top of preceding bearing before the front end of said tie-beam was fixed on, and the bottom of preceding bearing and cooresponding chassis side rail fix.
Adopt above technical scheme; The left and right outstanding journal stirrup of driving engine respectively with engine for motorcycle on cooresponding installation position be connected; Driving engine is by left and right outstanding journal stirrup supporting location, and left and right outstanding journal stirrup is supported by separately tie-beam, and the forward and backward two ends of tie-beam are equipped with suspending cushion; Be connected with bearing on the chassis side rail through suspending cushion, can guarantee that engine installation is firm so on the one hand; On the other hand, suspending cushion plays bumper and absorbing shock, and with the vibration between isolation driving engine and the chassis, and vibration isolating effect is good, has reduced the noise that engine vibration produces, and has improved the travelling comfort of motor-tricycle.
Said rear support is positioned at the plane at the left and right longeron of vehicle frame place, has 40-50 ° angle between the plane at said preceding bearing and the left and right longeron of vehicle frame place.Above structure make suspension system elastic center and driving engine barycenter near, can reduce the vertical shake and the torque vibration of driving engine greatly, further strengthened vibration isolating effect.
Suspending cushion is made up of first top board, first base plate, first rubber bodies and first bolt before said, and wherein the rear portion of first top board bends downwards, forms backplate, and this backplate welds with the front end of tie-beam mutually; Said first base plate is positioned at the below of first top board, connect through first rubber bodies between the two, and the end face of first base plate and preceding bearing fits, by first bolt that wears from top to bottom.More than simple and reliable for structure, fastness good, and vibration isolation is stable secure.
Same reason; Said back suspending cushion is made up of second top board, second base plate, second rubber bodies, second bolt and the 3rd bolt; Wherein second top board is " ∩ " shape; Second bolt and the rear end of tie-beam of the top of this second top board through from the bottom up fixed; In said second top board, second rubber bodies is set, the bottom of this second rubber bodies is coated with " ∪ " shape second base plate, and the bottom of this second base plate fixes through the 3rd bolt that wears from top to bottom and the cantilever end of rear support.
Beneficial effect: the present invention is reasonable in design, simple in structure, enforcement is easy; When guaranteeing that engine installation is firm; Can effectively isolate the vibration between driving engine and the chassis, and reduce the noise that engine vibration produces, improve the travelling comfort of motor-tricycle greatly.
