Abstract
The utility model is a double rocking arm type front suspension for motor vehicle, comprising a branch assembly, a base rocking arm and a shock absorbing pressing spring, wherein the lower end of the branch connects via a bolt with the front end of the base rocking arm; the upper end of the shock absorbing pressing spring connects via a pin with the middle part of the branch, the lower end connecting via a pin with the rear end of the base rocking arm; wheel shaft holes of a assembling wheel shaft is positioned at the middle part of the base rocking arm, the number of the wheel shaft holes being at least two. With the full utilization of the lever rule and multi-gravimetric point composition, the front wheel shaft holes are designed between the force point of the lower end of the frame assembly and the force point of the shock absorbing pressing spring, so the gravity of the front wheels of a motor vehicle is jointly borne by the frame assembly and the shock absorbing pressing spring, and according to the fatigue degree of the shock absorbing pressing spring, the front wheels may be positioned in a plurality of wheel shaft holes, making the motor vehicle more stable, more comfortable and more reliable, and also lengthening the useful life of the shock absorbing pressing spring and lowering the service cost of the vehicle.
Description
Technical field
The utility model relates to the front suspension structure of two-wheeled, motor-tricycle.
Background technology
The front suspension that present two-wheeled motor vehicle, motor-tricycle are gone up (comprising positive three-wheel, inclined to one side three-wheel, agricultural motor-tricycle) employing has hydraulic pressure cartridge type and mechanical shock absorption formula structure, the processing of hydraulic pressure cartridge type front suspension is difficult, manufacturing cost is higher, is difficult to use on the motor bike of various class.The mechanical shock absorption formula is used more relatively, it mainly is to be made of bracket assembly, end rocking arm and stage clip or extension spring, general structure be stage clip preceding, support after, the wheel shaft of wheel is installed in whole suspension the place ahead by end rocking arm, also has the wheel of minority structure to be mounted in the rear.This structure causes the motorcycle driving instability of getting up because the wheel installation site has determined the stress balance position of suspension can not digest the jerk power in travelling well, traveling comfort is poor, and stage clip is stressed bigger, and is tired easily, shortened its service life.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, provides a kind of self-propelled vehicle two rocker-arm front suspensions, improves driving stationarity, the traveling comfort of self-propelled vehicle, prolongs the service life of axle spring.
The technical solution of the utility model is as follows:
The two rocker-arm front suspensions of this self-propelled vehicle include connected to ground the pipe assembly in upper end, the rocking arm of a pair of end that links to each other with a pair of arm lower end of a pipe assembly and are connected in the middle part of the pipe assembly and a pair of damping stage clip between the end rocking arm.The front end of the lower end of described arm and end rocking arm is by bolted connection, and the upper end of damping stage clip is connected by bearing pin with the middle part of arm, and the lower end is connected by bearing pin with the rear end of end rocking arm, and the axle hole that wheel shaft is installed is arranged on the middle part of end rocking arm.
The described arm first half is a straight tube, and lower part has twice opposite press-bending of direction, can strengthen its stress performance like this, and end rocking arm is shortened, thereby reduces nose-wheel turn radius, makes to turn to become more flexible.In addition, when the damping stage clip is installed, make itself and arm first half straight tube in alignment, the stressed meeting of stage clip is better like this.
The axle hole at rocking arm middle part of the described end is provided with two at least, and in addition, in rocking arm rear end, the end, the lower position of corresponding damping stage clip point of connection also is provided with an axle hole, is convenient to adjust according to service condition the installation site of wheel shaft.
Described pipe assembly can adopt the symmetric double manifold configuration, is applicable to two-wheeled motor vehicle, and two arms upper end is connected with standpipe on the vehicle frame.In addition, a pipe assembly also can adopt the structure of being made up of the inverted T-shaped standpipe at symmetric double arm and top, is applicable to scooter and fully enclosed motor-tricycle, and the upper end of two arms and inverted T-shaped standpipe are fixed, and become one.
For motor-tricycle, also can connect the foundation ring at the front portion or the rear portion of end rocking arm, to play the equilibrium activity of protection wheel and car load.
The advantage of this structure is as follows: 1, this structure has made full use of the synthetic principle of lever and multiple force, the front-wheel axis hole is designed between the force and damping stage clip force of bracket assembly lower end, so middle axle hole also becomes a fulcrum, the gravity of the front-wheel of self-propelled vehicle is just born jointly by bracket assembly and damping stage clip, structure design is more reasonable, make motor-driven vehicle going more steady, reliability and traveling comfort are better.2, carried out special design to the curved shape of arm and with the annexation of stage clip, arm makes the stress performance of arm and stage clip all better, and end rocking arm is shortened, thereby reduces nose-wheel turn radius, makes to turn to become more flexible.3, because axle hole is provided with a plurality of on end rocking arm, especially the lower position at corresponding damping stage clip point of connection also is provided with an axle hole, be convenient to the degree of fatigue of front-wheel according to the damping stage clip, in a plurality of axle holes, carry out the position adjustment, selection reaches the optimum position of balance between two forces assembles, to guarantee the stability and the traveling comfort of vehicle '.4, the design of a plurality of axle holes in the also corresponding service life that increases the damping stage clip, has reduced the vehicle operation cost.5, simple in structure, be convenient to improve the working accuracy of whole suspension.
