Abstract
The invention relates to a shock absorption system for a rear axle of an electro-tricycle. The shock absorption system comprises at least two vertical shock absorption springs arranged between the rear axle and a tricycle frame, at least two forward-inclined type dampers connected to the middle of the rear axle and the middle of the tricycle frame, at least two double-arm type adjusting rods connected to the front end of the rear axle and the front end of the tricycle frame, and rear swing arms connected to the back of the rear axle and the back of the tricycle frame. The shock absorption springs, the dampers and the double-arm type adjusting rods are all symmetrically arranged on the two sides of the rear axle respectively. The shock absorption system can relieve up-and-down shock through the dampers and balance jolt in the running process; the stability of the rear axle is enhanced so that the tricycle frame will not shock due to vibration of a motor; the left-and-right swing of the tricycle frame in the running process of the tricycle is limited, the fatigue of passengers is relieved, the passengers can feel more comfortable, and the service life of the electro-tricycle is prolonged.
Description
Technical field
The present invention relates to a kind of damper of vehicle, be specifically related to a kind of electric tricycle rearmost axle shock mitigation system.
Background technology
Electric three-wheel is very universal at present, for people's transportation and the manned convenience that provides, but because electro-tricycle frame is simple in structure, it is also simpler and cruder that its shock absorption device designs, make vehicle in the process of moving, can produce violent vertical tremor and double swerve, the severity of jolting, affect the comfort that people take, and can damage vehicle frame and motor.
Summary of the invention
In order to address the above problem, the invention provides a kind of electric tricycle rearmost axle shock mitigation system, this shock mitigation system can be alleviated concussion up and down by damping spring and damper damping, balance jolting in travelling; Strengthened the stability of back axle, vehicle frame can not rocked because of the vibrations of motor; Limited swinging of vehicle frame in Vehicle Driving Cycle way, alleviated occupant's fatigue, made occupant more comfortable, and increased the service life of electro-tricycle.
The present invention is achieved by the following technical solutions: a kind of electric tricycle rearmost axle shock mitigation system, comprise the vertical damping spring of being located between back axle and vehicle frame, be connected in the FC damper at back axle and vehicle frame middle part, be connected in the double-arm adjust bar of back axle and vehicle frame front end, be connected in the rear arm at back axle and vehicle frame rear portion; Described damping spring, damper and double-arm adjust bar are all at least provided with two, and symmetrical back axle both sides of being located at respectively.
Described damping spring is fixedly supported on back axle by spring perch, and the top of damping spring contacts with the bottom surface of vehicle frame, and described damping spring is better than the elasticity of traditional leaf spring.
The two ends of described damper are hinged with the crossbeam at back axle leading flank and vehicle frame middle part respectively, described damper can slow down the stretching speed of damping spring, when spring stress action and reaction, and the damped device damping of energy, alleviate it and shake up and down, balance jolting in Vehicle Driving Cycle way.
Described double-arm adjust bar comprises a mobile jib and is welded in minute bar at this mobile jib rear portion, and the end of described mobile jib and minute bar is equipped with hinged cover, and the downward-extension frame of the front end of described mobile jib and vehicle frame front portion is hinged; The rear portion of described mobile jib and minute bar are all hinged with the support being welded on back axle, make double-arm adjust bar and back axle form a stable triangular structure, have strengthened the stability of vehicle frame.
Described rear arm tilts to be connected between back axle and vehicle frame, the low side of described rear arm and back axle one end are hinged, high-end and the back axle other end of rear arm is hinged to the rear arm seat of downward-extension, for fixedly back axle and vehicle frame rear portion, makes back axle and vehicle frame stretch and can not swing up and down.The design of described rear arm seat has reduced the connection angle of rear arm and back axle, and when back axle and vehicle frame are flexible up and down, the pendulum of rear arm effect back axle is apart from the shortest.
The invention has the beneficial effects as follows: a kind of electric tricycle rearmost axle shock mitigation system, this shock mitigation system can damped device damping alleviate concussion up and down, balance jolting in travelling; Strengthened the stability of back axle, vehicle frame can not rocked because of the vibrations of motor; Limited swinging of vehicle frame in Vehicle Driving Cycle way, alleviated occupant's fatigue, made occupant more comfortable, and increased the service life of electro-tricycle.
