Abstract
A shock absorber and turning to and connecting the board to have no loose junction device, adopt the conical surface to connect between link plate of the shock absorber shank and turning to, tighten up and fix with the nut, there is a compensation hole greater than the internal thread bottom diameter at the bottom end of internal diameter of nut, correspond to the tool withdrawal groove on the shock absorber taper shank while assembling; the top end of the shock absorber taper shank is provided with a screw plug, and the outer diameter of the cap head of the screw plug is smaller than or equal to the top diameter of the internal thread of the nut. The utility model overcomes the existing problem that can not auto-lock, easy fracture etc. of connection structure exist has the characteristics of connecting safe and reliable, and the specially adapted steering wheel formula motor tricycle uses.
Description
The utility model relates to the connecting device of self-propelled vehicle front suspension system, particularly bumper and connecting plate.
Bearing circle motor tricycles transport trolley no matter at vehicle modeling still aspect the traveling comfort of driving, all obtained market and the consistent of traffic management system and approved.But the front suspension system design aspect in car load and since bumper with turn to an ideal is not arranged being connected of connecting plate and the practicality scheme, make user, manufacturer and traffic control department produce sense of insecurity.For this problem, in the past few years some producers have successively taked multiple measure, attempt to solve the connectivity problem of bumper and connecting plate, but all still have generation because of the deficiency train operation accident of design aspect.The connecting device of prior art and principal mode have following several:
1. taper shank structural couplings:
(1) cone match, plug screw are tightened and are sealed.
The bumper shank adopts cone, be connected with the taper hole that turns to connecting plate, fix with plug screw, be with " O " shape seal ring at the Gewindefreistiche place of plug screw, assembling back since screw thread to screw power little, plug screw compresses end face and turns to the connecting plate contact surface too small, and also accompanies the interference of round section joint ring in the middle of being, can not satisfy the required pressure of the conical surface after the assembling.
(2) cone match, single nut is tightened.
The bumper shank adopts cone, be connected with the taper hole that turns to connecting plate, single nut screws the back and is equipped with the round section joint ring sealing with plug screw, this device has had progress than above-mentioned connection mode, but weak point is: 1. the screw thread selected for use of single nut is only considered the intensity of screw thread, self-locking performance is poor, and the power that screws is little, can not satisfy conical surface self-locking pressure and shock proof requirement; 2. the requirement of the quality of fit of taper hole and taper shank is too high, and the run-out(of thread) of taper shank does not have relief groove, easily produces the interference of seal face when nut screws.
2. staight shank structural couplings
As shown in Figure 1, be bumper shank in the prior art and the constructional drawing that turns to connecting plate to adopt staight shank to cooperate.It is characterized in that: change staight shank into by above-mentioned taper shank structure.Phenomenon of rupture and various train operation accident still often appear in this kind device in use.
The purpose of this utility model provide a kind of can satisfy self-locking with and the critical bumper of asking with turn to the connecting plate connecting device.
According to above-mentioned purpose, technical solution adopted in the utility model is:
1. bumper shank and turning between connecting plate is selected the good cone match of self-locking property for use, to satisfy the radially static friction force transfer torque of fitting surface, and reciprocal impulsive force and moment of deflection when axially bearing the bumper acting.
2. add major thread and screw power, adopt to add long nut or with two nuts and tight, interference-free when turning to the connecting plate upper surface to tighten when both having guaranteed that lower nut screws, improve the also sigma compactness and the self-locking performance of screw thread again.
3. lower nut internal diameter lower end has the compensation orifice greater than end footpath, with avoid because of the bumper taper shank with turn to the connecting plate taper hole cooperate overproof cause screw not tight.
4. in the connecting thread lower end of bumper shank, that is the cone small end of taper shank and its outside thread intersection, be provided with relief groove, with overcome because of cone match to the too high deficiency of accuracy requirement.
The utility model has the advantages that:
(1) the connecting device self-locking performance is good, loosening phenomenon can not occur;
(2) the plane of weakness modulus is big, intensity height, strained condition ideal;
(3) good manufacturability, the assembling of bumper, use, easy to maintenance.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1. be the connecting device scheme drawing of prior art.
Shank for bumper shown in the figure is that staight shank cooperates with the junction that turns to connecting plate, and single nut screws the back and is equipped with the round section joint ring sealing with plug screw.
Fig. 2 is the scheme drawing of an embodiment of non-loosening connecting device.
Among the figure: 1 for turning to connecting plate, and 2 is bumper shank (taper shank), and 3 is the nut breach, and 4 is relief groove, and 5 is nut, and 6 is round section joint ring, and 7 is plug screw.
In the embodiment of Fig. 2, the bumper shank is that taper shank 2 partly is cone with turning to connecting plate 1 bonded assembly, match with the taper hole on turning to connecting plate 1, cone small end and outside thread intersection have a relief groove 4, and bumper shank 2 is with to turn to connecting plate 1 usefulness nut 5 to tighten fixing, are the structure of two nuts of employing shown in the figure, when reality is used, also can adopt the nut of a lengthening,, a breach 3 that is slightly larger than footpath at the bottom of the nut inner thread be arranged in the lower end of lower nut internal diameter; On the top of bumper shank, a plug screw 7 is arranged, O-ring seals is arranged on the plug screw, the external diameter of plug screw cap head is slightly less than nut inner thread Xiang Jing.
The utility model is applicable to three wheeled motor car.
Claims (2)
1, a kind of bumper and the connecting device that turns to connecting plate, bumper shank (2) is a cone, link to each other with the taper hole that turns to connecting plate (1), both tighten fixing with nut (5), the top of bumper shank (2) seals with plug screw (7), it is characterized in that a compensation orifice greater than the core diameter of thread (3) is arranged under nut (5) internal diameter, the external diameter of plug screw (7) cap head is less than or equal to the footpath, negative thread top of nut (5).
2, bumper as claimed in claim 1 and the connecting device that turns to connecting plate, its special card is that bumper shank (2) cone small end and outside thread intersection have relief groove (4).
