Abstract

The utility model discloses a front axle shock absorber of an electric quadricycle in the field of quadricycle shock-absorbing devices, which comprises a casing pipe provided with a front axle fixing plate on the side surface thereof, wherein the casing pipe consists of a minor diameter section of the upper part and a major diameter section of the lower part, the upper end of the casing pipe is closed, a expansion pipe is inserted into one end of the major diameter section inside the casing pipe and then inserted into the minor diameter section, the upper end of the expansion pipe is closed, an elastic mechanism is arranged at the upper end of the expansion pipe and the closed end of the casing pipe, a long screw rod penetrates the closed end of the expansion pipe, the center of the elastic mechanism and the closed end of the casing pipe and connects together the expansion pipe and the casing pipe, an abrasion resistant guide bush is arranged between the inner wall of the major diameter section of the casing pipe and the expansion pipe, the lower end of the expansion pipe is connected with a wheel fixing shaft and a steering arm, and a plane bearing is arranged between the lower end of the elastic mechanism and the upper end of the expansion pipe. Through the addition of the plane bearing, the wheel steering moment becomes small, and the wheel steering angle is equal to that of the steering wheel or the handle. The device can be applied to light and mini type electric quadricycles.

Description

Electric four-wheel vehicle propons bumper

Technical field

The utility model relates to a kind of shock absorption device of four-wheeled, particularly the propons bumper of light four-wheel car.

Background technology

In the prior art, the propons bumper of automobile, mainly comprise sleeve pipe, sleeve pipe is made of the path section on top and the big footpath section of bottom, the sleeve pipe upper end closed, be inserted with telescopic pipe from big footpath Duan Yiduan in the sleeve pipe, telescopic pipe is inserted in the path section, the telescopic pipe upper end closed, the telescopic pipe upper end is provided with elastic mechanism with the closed end of sleeve pipe, a long bolt passes the closed end of telescopic pipe, the closed end of elastic mechanism center and sleeve pipe is connected telescopic pipe with sleeve pipe, be provided with the wear-resistant guiding lining between the internal surface of sleeve pipe of big footpath section and the telescopic pipe, the telescopic pipe lower end is connected with wheel anchor shaft and spindle arm, can spur telescopic pipe by spindle arm and rotate, thereby driving the wheel anchor shaft rotates, realize wheel steering, also be provided with the propons adapter plate, whole device can be connected on the vehicle frame by the propons adapter plate in the side of sleeve pipe, because the power-assisted of direction machine and hydraulic efficiency pressure system is arranged, and operator's direction of passage dish drive wheels easily turns to; Telescopic pipe compression spring when running into vibrations is realized damping, avoids jolting.Its weak point is: need the power-assisted of direction machine just can finish during the work of this bumper and turn to, bearing circle can not directly drive spindle arm and realize equal angular turning to, its reason is that the friction force in the steering procedure is big, make turn to very difficult, must could realize turning to smoothly by other mechanisms, the bearing circle rotational angle when turning to be much larger than the steering angle of wheel.

The utility model content

The purpose of this utility model provides a kind of propons bumper of electric four-wheel vehicle, makes bearing circle can drive spindle arm and realizes equal angular turning to.

The purpose of this utility model is achieved in that electric four-wheel vehicle propons bumper, comprise that the side is provided with the sleeve pipe of propons adapter plate, sleeve pipe is made of the path section on top and the big footpath section of bottom, the sleeve pipe upper end closed, be inserted with telescopic pipe from big footpath Duan Yiduan in the sleeve pipe, telescopic pipe is inserted in the path section, the telescopic pipe upper end closed, the telescopic pipe upper end is provided with elastic mechanism with the closed end of sleeve pipe, a long bolt passes the closed end of telescopic pipe, the closed end of elastic mechanism center and sleeve pipe is connected telescopic pipe with sleeve pipe, be provided with the wear-resistant guiding lining between the internal surface of sleeve pipe of big footpath section and the telescopic pipe, the telescopic pipe lower end is connected with wheel anchor shaft and spindle arm; Be provided with surface bearing between elastic mechanism lower end and the telescopic pipe upper end.

During the utility model work, connect by the propons adapter plate and to be fixed on the vehicle frame, wheel is installed on the wheel anchor shaft, and spindle arm is connected with bearing circle or handle, car body can be delivered to ground by surface bearing to ground-surface pressure, when needs turned to, bearing circle or handle drove telescopic pipe by spindle arm and rotate the surface bearing servo-actuated, realize wheel steering smoothly, its steering torque is little, turns to easy and flexible, and the wheel steering angle can equate with bearing circle or handle steering angle; Run into and jolt or when shaking, telescopic pipe can push elastic mechanism and move up and down the position, realize damping, the wear-resistant guiding lining play the guiding role, and makes that telescopic pipe both can up-and-down movement, can conveniently rotate again.Elastic mechanism can be spring, also can be dampings such as hydraulic die cushion, cushion.This device can be used on light-duty, the miniature electric four-wheel vehicle, have simple in structure, turn to advantage easily.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the birds-eye view of Fig. 1.

Wherein, 1 wheel anchor shaft, 2 spindle arms, 3 wear-resistant guiding linings, 4 telescopic pipes, 5 surface bearings, 6 sleeve pipes, 601 big footpath sections, 602 path sections, 7 long bolts, 8 springs, 9 upper head plates, 10 nuts, 11 propons adapter plates.

The specific embodiment

As Fig. 1 and 2, electric four-wheel vehicle propons bumper, comprise that the side is provided with the sleeve pipe 6 of propons adapter plate 11, sleeve pipe 6 is made of the path section 602 on top and the big footpath section 601 of bottom, sleeve pipe 6 upper ends are through upper head plate 9 sealings, be inserted with telescopic pipe 4 from big footpath section 601 1 ends in the sleeve pipe 6, telescopic pipe 4 is inserted in the path section 602, telescopic pipe 4 upper end closeds, the closed end of telescopic pipe 4 upper ends and sleeve pipe 6 is provided with spring 8, a long bolt 7 passes the closed end of telescopic pipe 4, the closed end of spring 8 centers and sleeve pipe 6, the external part of long bolt 7 is connected telescopic pipe 4 through nut 10 with sleeve pipe 6, be provided with wear-resistant guiding lining 3 between sleeve pipe 6 inwalls of big footpath section 601 and the telescopic pipe 4, telescopic pipe 4 lower ends are connected with wheel anchor shaft 1 and spindle arm 2; Be provided with surface bearing 5 between spring 8 lower ends and telescopic pipe 4 upper ends.

During work, connect by propons adapter plate 11 and to be fixed on the vehicle frame, wheel is installed on the wheel anchor shaft 1, and spindle arm 2 is connected with bearing circle or handle, car body can be delivered to ground by surface bearing 5 to ground-surface pressure, when needs turned to, bearing circle or handle drove telescopic pipe 4 by spindle arm 2 and rotate surface bearing 5 servo-actuateds, realize wheel steering smoothly, its steering torque is little, turns to easy and flexible, and the wheel steering angle can equate with bearing circle or handle steering angle; Run into and jolt or when shaking, but telescopic pipe 4 extrusion springs 8 move up and down the position, realize damping, wear-resistant guiding lining 3 play the guiding role, and makes that telescopic pipe 4 both can up-and-down movement, can conveniently rotate again.
