Technical Field

The invention relates to an engine suspension system used on a motor tricycle, in particular to an engine suspension system which is suitable for mounting a pedal motorcycle stepless speed change engine and a reverse gear on a frame of the motor tricycle by using the pedal motorcycle stepless speed change engine as power.

Background

The known motor tricycle at present, the engine is installed on the engine bracket, the engine bracket is installed on the frame of the motor tricycle by three or four shock-absorbing assembly connections, the engine power is transmitted to the rear axle of the motor tricycle through the transmission shaft via the reverse gear, when the load capacity of the motor tricycle changes or runs on bumpy road surface, the wheel and the rear axle swing in the vertical direction relative to the frame and the engine and the reverse gear, the swing of the two ends of the two universal joints at the two ends of the transmission shaft is buffered, because the angle that the two ends of the universal joint of the transmission shaft can swing is smaller, when the swing angle exceeds a certain limit, the universal joint is excessively worn and damaged, and then the durability and reliability of the motor tricycle are affected, therefore, when the motor tricycle with the structure is designed, the distance between the engine and the rear axle must be ensured to be capable of placing the transmission shaft with enough length, so as to ensure that the swinging angle of the two ends of the universal joint does not exceed the allowable angle when the transmission shaft with enough length swings at the rear axle. The engine used by the traditional motor tricycle is short in longitudinal size and relatively far away from the rear axle of the motor tricycle, and even if the motor tricycle is a small motor tricycle with a short body, the space between the engine and the rear axle is enough for arranging the transmission shaft with proper length. However, when some small motorcycles having a relatively short body use the scooter type continuously variable transmission engine as power, since the scooter type continuously variable transmission engine has a relatively long longitudinal dimension, the distance between the engine and the rear axle is relatively short, and only a transmission shaft having a short length can be used, and an excessively short transmission shaft causes a change in the load capacity of the motor tricycle or a swing angle at both ends of a universal joint of the transmission shaft caused by a vertical swing of wheels and the rear axle when the motor tricycle runs on a bumpy road surface to exceed an allowable limit, resulting in excessive wear and damage of the universal joint.

Disclosure of Invention

The invention provides an engine suspension system used on a motor tricycle, which aims to solve the problems of excessive wear and damage caused by overlarge swinging angle of a universal joint of a transmission shaft due to the fact that the longitudinal dimension of a pedal motorcycle stepless speed change engine is longer and only a transmission shaft with a short length can be used when the motor tricycle adopts the pedal motorcycle stepless speed change engine as power.

The invention adopts the technical scheme that the motor tricycle comprises a frame (1), a pedal motorcycle stepless speed change engine (2), a rear axle (4), a reverse gear (6) and the like. The engine suspension system consists of a cross rod (9), a longitudinal rod (11), a support frame (3) and a support frame (5), wherein two ends of the cross rod (9) are hinged on the support frame (3) on two main beams of a frame (1) through screw rods, a steel pipe (12) at one end of the longitudinal rod (11) is hinged on a connecting plate (10) on the cross rod (9) through the screw rods (14), the other end of the longitudinal rod is hinged on the support frame (5) on a rear axle (4) through the screw rods, a mounting seat (13) is arranged on the longitudinal rod (11), a reverse gear fixing plate is used for fixing a reverse gear (6), a power input shaft of the reverse gear (6) is connected on a final shaft of the stepless speed change engine of the pedal motorcycle, a power output shaft is connected on a power input shaft of a main reduction differential (8) on the rear axle (4) through a transmission shaft (7), a waist mounting hole seat of the stepless speed change engine (2) of the pedal motorcycle is simultaneously hinged on the connecting plate (10) on the cross rod (9) and the longitudinal rod (14) through the screw rods (5) (11) The tail mounting hole seat of the pedal motorcycle stepless speed change engine (2) is hinged on a mounting seat (13) on the longitudinal rod (11) by a screw rod on the steel pipe (12). Or the engine suspension system is composed of a cross rod (15), a longitudinal rod (19), a support frame (3) and a support frame (5), two ends of the cross rod (15) are hinged on the support frame (3) on two main beams of the frame (1) through screw rods (16), one end of the longitudinal rod (19) is fixed on the cross rod (15), the other end of the longitudinal rod is hinged on the support frame (5) on the rear axle (4) through screw rods, a mounting seat (20) is arranged on the longitudinal rod (19), a reverse gear fixing plate is used for fixing a reverse gear (6), a power input shaft of the reverse gear (6) is connected on a final shaft of the pedal motorcycle stepless speed change engine, a power output shaft is connected on a power input shaft of a main reduction differential (8) on the rear axle (4) through a transmission shaft (7), a waist mounting hole seat of the pedal motorcycle stepless speed change engine (2) is hinged on a steel pipe (17) on the cross rod (15) through screw rods (18), the tail mounting hole seat of the pedal motorcycle stepless speed change engine (2) is hinged on a mounting seat (20) on a longitudinal rod (19) by a screw rod.

The invention has the advantages that when the pedal motorcycle stepless speed change engine is adopted as power for the motor tricycle, the engine suspension system provided by the invention can reduce the swing angle of two ends of the universal joint on the transmission shaft caused by the swing of wheels and a rear axle when the motor tricycle is driven on a bumpy road surface or the load capacity of the motor tricycle to an allowable limit, thereby avoiding the excessive abrasion and damage of the transmission shaft and the universal joint.
