Abstract
The utility model relates to a front wheel damping device for tricycle, for avoid the front wheel to break away from the automobile body, improve tricycle front wheel anti-seismic performance design. The structure of the suspension comprises a sleeve and a front wheel shaft, wherein the sleeve is connected with the front wheel in a direction shaft, two ends of the front wheel shaft are connected onto a shaft sleeve through pin shafts, the shaft sleeve is welded on a lower fixing plate of a spring plate, two ends of the spring plate are connected to the lower end parts of front and rear arms of a triangular suspension in a rolling mode through the pin shafts, and the upper ends of the front and rear arms of the suspension are fixedly connected with the upper end. The utility model provides a front wheel axle passes through fixed connection between spring plate and the triangle-shaped suspension, can not appear because of the too big condition that leads to the front wheel axle to break away from the frame of amplitude, consequently, when the tricycle went on the road of pot hole unevenness, can not break away from the condition of automobile body because of the too big front wheel that appears of top, has improved the factor of safety of tricycle when various unevenness's road surface is gone effectively.
Description
Technical field
The utility model relates to a kind of vehicle shock-absorbing device, specifically a kind of three-wheel automobile front wheel shock absorption device.
Background technology
The front-wheel shock absorption device of existing three-wheel vehicle is that the sleeve pipe upper end is set with spring on the axis of orientation that joins with handlebar, and the lower end of last sleeve pipe is stretched in the case in and offseted with the spring that is positioned at the case in bottom, cased lower end installation front-wheel pivot shaft.Because the upper and lower sleeve pipe of this front-wheel shock absorption device like this, when the travels down of road injustice, can cause the separation of upper and lower sleeve pipe for flexibly connecting when amplitude is too big, thereby cause front vehicle wheel to break away from car body, cause major traffic accidents.
The utility model content
The purpose of this utility model just provides a kind of three-wheel automobile front wheel shock absorption device, to increase the anti-seismic performance of front-wheel, avoids front-wheel to break away from car body, improves the travel safety of three-wheel vehicle.
The utility model is achieved in that the front-wheel shock absorption device comprises and front-wheel axis of orientation bonded assembly sleeve pipe and front wheel spindle, the front wheel spindle both ends are connected on the axle sleeve by bearing pin, axle sleeve is welded on the bottom plate of spring plate, the two ends of spring plate are by the bottom of bearing pin cigarette arm before and after the triangle suspension, and the upper end of arm and front fork upper end is affixed before and after the suspension.
When travelling, the triangle suspension that axis of orientation joins by sleeve pipe, with sleeve pipe, the spring plate of triangle suspension lower end drive front wheel spindle control front-wheel steering.When road was uneven, front vehicle wheel rose to scend, and the spring plate affixed with front wheel spindle plays buffer action to the scend of front truck wheel shaft.Adopt this structure, front wheel spindle is captiveed joint by between spring plate and the triangle suspension, can not break away from vehicle frame because of amplitude causes front wheel spindle when excessive, therefore, when three-wheel vehicle travels on potholed road, can be because of a top excessive situation that front-wheel disengaging car body occurs, this has just improved the safety factor of three-wheel vehicle when the road traveling of various injustice effectively.
The utility model can also be realized like this: on the basis of said structure, and affixed bottom girder between the bottom of arm before and after suspension, end face is connected with socket on the upper mounted plate of spring plate, is inserted with rubber block in the socket, and rubber block is vertically relative with the bottom girder middle part.
Adopt this structure, when amplitude was big, the spring plate middle part caused the rubber block upper punch to upper process.Bottom girder following carries out spacing to the rubber block with its vertically relative upper punch, thereby avoided significantly vibration down, and the spring plate that is caused when prominent excessive on the spring plate fractures, thereby further improved the safety in operation of three-wheel vehicle.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this device comprises and front-wheel axis of orientation bonded assembly sleeve pipe 9 and front wheel spindle 2, the front wheel spindle both ends are connected on the axle sleeve 1 by bearing pin 3, axle sleeve 1 is welded on the bottom plate 4 of spring plate 6, the two ends of spring plate 6 are by the bottom of bearing pin cigarette at triangle suspension forearm 8 and postbrachium 10, the connection mode of spring plate 6 and forearm 8 and postbrachium 10 can adopt the spring plate interconnection technique of vehicle rear wheel in the prior art.Wherein, spring plate 6 can rotate around bearing pin with the attaching parts of postbrachium 10, with in the process of moving, adapts to stretching with crooked of bow font spring plate.The upper end of the upper end of forearm 8 and postbrachium 10 and sleeve pipe 9 is affixed.
Affixed bottom girder 7 between the bottom of the forward and backward arm of suspension is connected with socket 12 at the end face of the upper mounted plate 13 of spring plate 6, is inserted with rubber block 11 in the socket 12, and rubber block is vertically relative with bottom girder 7 middle parts.
Be the bending of upper process in the middle part of preferably bottom girder 7 being made, and affixed with the bottom of sleeve pipe 9.Like this, on the one hand, bottom girder 7 can increase the bearing force of forearm 8 and postbrachium 10; On the other hand, can utilize sleeve pipe 9 to increase the impact resistance of bottom girder 7.
Being connected with spacing button 5 on the spring plate 6 of this device, turns up in the both sides of spacing button 5, and has the through hole of cross-under locking piece.The locking piece cross-under is in through hole, spacing padlock is tight, occur to avoid when three-wheel vehicle two trailing wheels are in rugged position, because of front-wheel, departing from the phenomenon that cross travel takes place between each plate face of bow font spring plate that vertical direction caused, thereby further improve the safety in operation of three-wheel vehicle.
