Abstract
The utility model discloses a front suspension device for three-wheel vehicles, which is characterized in that the lower end of a steering crank arm (4) provided with a direction column is hinged with a vibration damping swinging arm (3) whose one end is fixedly connected with a front shaft (8), one end of a vibration damper assembly (1) is connected with the front shaft (8), and the other end is connected with a vibration damping supporting seat arranged on the steering crank arm (4) for positioning purpose. The utility model with the advantages of effect increase of the comfort characteristic and the service performance of a complete vehicle and long service life of the vibration damper can be widely used in the field of the front suspension of three-wheel vehicles.
Description
The utility model relates to the front wheels of motor-vehicles suspension gear, specifically a kind of motor tricycle front-end equipment.
At present, domestic motor bike, the front-wheel of three-wheel transporter hang and steering swivel system all adopts two-way cylinder type hydraulic shock absorber, and promptly direction of passage yoke plate, Steering gear, steering handle or bearing circle constitute the vehicle front suspension.There is following shortcoming in this forward mounting structure: the one, and shock absorber is when playing damping of vibrations, also to play the guiding role, because the guidepost of shock absorber is thicker, under the situation of identical stroke, hydraulic pressure amount by damping hole is just little many, make the indicator diagram of shock absorber produce mutation, thereby the desirable effectiveness in vibration suppression of out of reach cause the car load traveling comfort poor.The 2nd, when playing the guiding role, shock absorber will bear moment of flexure, produces bigger static friction force between guidepost and orienting sleeve, makes the guidepost and the aggravation of the wearing and tearing between the orienting sleeve of shock absorber, causes the premature wear of shock absorber, produces leakage of oil, and service life is low.
The purpose of this utility model is under the prerequisite that improves the motor bike design level traveling comfort of car load and in-use performance to be improved, and prolongs the service life of shock absorber.
The utility model is finished as follows:
Positive three-wheel vehicle front-end equipment, comprise vibration damper complement, brake assembly, it is characterized in that the articulated end in the lower end that turns to connecting lever that described positive three-wheel vehicle front-end equipment is equipped with the direction post is connected in the vibration damping swing arm on the front axle, described vibration damper complement one end links to each other with front axle, and the other end is connected the location with the vibration damping holder that turns to connecting lever to be provided with.
Describedly turn to connecting lever and vibration damping swing arm to be hinged with bearing pin.
Turn to connecting lever because original direction yoke plate and direction post be integrated to become, increase a vibration damping swing arm, turning to connecting lever to pass through a bearing pin is connected with the vibration damping swing arm, the vibration damping swing arm with turn to connecting lever with to relatively rotate, like this during Vehicular turn, drive the vibration damping swing arm when direction post rotates around certain rotational, realize turning to.
Preceding wheel assembly is connected with the vibration damping swing arm, can together rotate around bearing pin with the vibration damping swing arm when wheel bounce.
Shock absorber one end links to each other with front axle, the other end is connected with vibration damping holder on turning to connecting lever, when wheel bounce, play damping of vibrations, shock absorber can be freed from directional tagging like this, make it only to rise damping of vibrations, do not play the guiding role, it is poor fundamentally to have solved the car load traveling comfort, the shock absorber easy oil leakage, the shortcoming that service life is poor.
The utility model compared with prior art has the following advantages: the one, and car load traveling comfort and in-use performance effectively improve; The 2nd, shock absorber can improve more than 30% service life; The 3rd, simple in structure, be convenient to make.
Now in conjunction with the accompanying drawings, enumeration embodiment of the present utility model.
Fig. 1 is an integral structure front view of the present utility model, 1 vibration damper complement wherein, and 2 damper springs, 3 vibration damping swing arms, 4 turn to connecting lever.
Fig. 2 is that partial view is looked on the right side of the present utility model, 6 braking hubs wherein, 7 brake assemblys, 8 front axles.
Fig. 3 is the A-A cross section view among Fig. 1, wherein 5 bearing pins.
Positive three-wheel vehicle front-end equipment, comprise vibration damper complement (1), brake assembly (7), the articulated end in the lower end that turns to connecting lever (4) that its main points are to be equipped with in the described positive three-wheel front-end equipment direction post is connected in the vibration damping swing arm (3) on the front axle (8), described vibration damper complement (1) one end links to each other with front axle (8), and the other end is connected the location with the vibration damping holder that turns to connecting lever (4) to be provided with.
Turn to connecting lever (4) and vibration damping swing arm (3) to be hinged with bearing pin (5).
Claims (2)
1, a kind of positive three-wheel vehicle front-end equipment, comprise vibration damper complement (1), brake assembly (7), it is characterized in that the articulated end in the lower end that turns to connecting lever (4) that described positive three-wheel vehicle front-end equipment is equipped with the direction post is connected in the vibration damping swing arm (3) on the front axle (8), described vibration damper complement (1) one end links to each other with front axle (8), and the other end is connected the location with the vibration damping holder that turns to connecting lever (4) to be provided with.
2,, it is characterized in that describedly turning to connecting lever (4) and vibration damping swing arm (3) to be hinged with bearing pin (5) by the described a kind of positive three-wheel vehicle front-end equipment of claim 1.
